REASONS FOR VERDICT
M M
N 1. The defendant pleads not guilty to one charge of possession N
of child pornography, contrary to section 3(3) of the Prevention of Child
O O
Pornography Ordinance 1 (charge 1), and one charge of possession of
P apparatus for radiocommunications without a licence, contrary to section P
8(1)(b) and section 20(a) of the Telecommunications Ordinance,2 (charge
Q Q
2).

Introduction
C C
2. In summary on the evening of the 29th January 2014 the
D police executed a search warrant at Flat D, 9/F, Lok Moon Mansion, 29- D
31 Queen’s Road East in Wan Chai, where the defendant resided together
E E
with his parents and younger sister.
F F
3. The police seized from the defendant’s bedroom a white
G G
desktop computer (“the computer”) and three radio-transceivers.
H Subsequent forensic examination of the computer by DSPC 23344 of the H
Technology Crime Division revealed that sixteen video files and thirteen
I I
photo files suspected to be child pornography were stored on the
J computer. Ten of the video files and four of the photo files are the J
subject of charge 1. The photo files were originally referred to in the
K K
charge as four photo images. This was later amended to read four still
L films. I will in my verdict refer to these as photo files the term used by L
DSPC 23344.
M M
N 4. The three radio-transceivers were examined by Mr Lau Yat N
Fan, an assistant inspector of communications with the Communications
O O
Authority, who found them to be apparatus for radiocommunications, for
P which a licence is required. P
Q Evidence Q
R R
5. The prosecution called three witnesses referred to in the
S opening, namely: PC 4440 (PW2), who seized the computer and the three S
radio-transceivers and drew a sketch of the flat (exhibit P9); DSPC 23344
T T
(PW4) and Mr Lau Yat Fan (PW6).

6. Facts have been admitted pursuant to section 65C of the
C Criminal Procedure Ordinance3 (exhibits P8, P8A, P8B & P8C). I will C
refer to the admitted facts as I review the evidence.
D D
7. The defendant elected to give evidence. No witnesses were
E E
called on his behalf. Admitted in evidence is that the defendant has no
F criminal convictions.4 I direct myself as to good character in accordance F
with the decision in HKSAR v Tang Siu Man5.
G G
H 8. In reaching my verdict I remind myself of the burden and H
standard of proof and that the burden is on the prosecution throughout.
I I
The defendant has to prove nothing. I direct myself that I must be sure of
J the defendant’s guilt on each charge, each charge being considered J
separately. On the other hand if the court thinks that the defence
K K
evidence pointing to innocence is true or may be true, it would follow that
L the defence has raised sufficient doubt in the prosecution case and the L
defendant entitled to be acquitted.
M M
N 9. I remind myself that when drawing inferences from the N
evidence the inference must be the only reasonable inference to draw
O O
from the proved facts. If from the facts proved there is a reasonable
P inference to draw against the defendant as well as one in his favour the P
adverse inference cannot be drawn.
Q Q
10. I have carefully considered all the evidence and the written
R R
submissions of Mr Tracy and Mr Boyton. I have in court expressed in

B B
very strong terms, more than once, my view as to Mr Tracy’s submission
C on charge 1. I do not propose to repeat those criticisms here. C
D Charge 1 - Possession of child pornography D
E E
11. On a charge under section 3(3) of the Ordinance the
F prosecution must prove beyond reasonable doubt that the defendant was F
in possession of the child pornography. This involves the prosecution
G G
proving that the defendant had control of and knowledge of the existence
H of the video files and photo files on the computer but not that the H
defendant knew they were child pornography (see HKSAR v Justin Yves
I I
Herbonnet6; Atkins v DPP 7 and McMurdo v HM Advocate8).
J J
12. Save that the computer was found in the defendant’s
K K
bedroom the prosecution opening does not say on what evidence the
L
prosecution rely upon to prove that the defendant was aware of the video L
files and photo files on the computer. The opening simply states the
M M
seizing of the computer and the finding of the child pornography on the
N computer. N

13. When asked by the court what evidence the prosecution will
C seek to adduce with regards to knowledge Mr Tracy recognizing that C
knowledge was the issue in the case stated that the court would be asked
D D
to infer knowledge from the circumstances of the finding of the computer;
E the admissions to be made by the defendant that he was the owner and in E
possession of the computer on the material day; and the evidence of
F F
DSPC 23344.
G G
14. The defence case in summary is that the defendant was not
H aware that the video files and the photo files were on his computer. The H
defendant says that he believed there was a virus on the computer and
I I
therefore the child pornography may have been downloaded by the virus.
J J
The defendant also says that the computer was used by his parents,
K
younger sister and her boyfriend and anyone else who visited the home. K
The defence contend therefore that the defendant was not in exclusive
L L
control of the computer and thereby implying other users of the computer
M
may have downloaded the child pornography without the knowledge of M
the defendant.
N N
15. If the defendant was not aware that the video files and the
O O
photo files were on his computer is true or may be true the defendant is
P entitled to be acquitted (see Atkins v DPP). 9 If the prosecution prove P
beyond reasonable doubt that the defendant was in possession of the child
Q Q
pornography the defendant may rely on any of the statutory defences set
R out in section 4 of the Ordinance. R

16. By saying he was not aware of the child pornography on his

that he had not seen the child pornography and did not know nor suspect
D D
it to be child pornography.10
E E
Prosecution evidence
F F
17. I now turn to consider the evidence. The principal evidence
G G
adduced by the prosecution is that of DSPC 23344 Tsang Nung Keung.
H DSPC 23344 retired in June this year. In my verdict I will refer to Mr H
Tsang as DSPC 23344. Three statements of DSPC 23344 have been read
I I
pursuant to section 65B of the Criminal Procedure Ordinance11 (exhibits
J P10, P11 & P12) and adopted as part of his evidence-in-chief. J
K K
18. There was no challenge to the expertise of DSPC 23344.
L
DSPC 23344 had worked in the Technology Crime Division since L
September 2005 and held various qualifications in computing. I was
M M
satisfied DSPC 23344 was able to give expert evidence on computer
N forensic examination. N
O 19. DSPC 23344 examined the hard disc of the computer and O
found the child pornography subject of the charge. In evidence DSPC
P P
23344 said he conducted the examination with the forensic programme
Q Encase. After examining the hard disc DSPC 23344 restored the hard Q
disc contents to one “Western Digital” external USB hard disc, exhibit P5.

This is referred to in the admitted facts as a disc cloned from the hard

D 20. In order that the court could fully understand all aspects of D
the expert evidence this necessitated lengthy questioning by the court
E E
both during and at the end of the evidence of DSPC 23344 including
F asking DSPC 23344 to demonstrate how the user of the computer could F
access the video files and the photo files.
G G
H 21. Unless otherwise stated I accept the expert evidence of H
DSPC 23344. I do not propose to set out here a detailed summary of the
I I
expert evidence. I will refer to the relevant parts when reviewing the
J evidence. J
K K
Finding of the child pornography
L L
22. The finding of the child pornography on the computer has
M not been challenged and can therefore be briefly stated. DSPC 23344 M
found on the hard disc of the computer sixteen video files of suspected
N N
child pornography and thirteen photo files of suspected child
O pornography and personal photographs of suspect (see paragraph 5 of O
both the first and second statements of DSPC 23344, exhibits P10 & P11).
P P
Q 23. The video files and photo files are listed in Annex A to both Q
the statements (marked exhibits P10A and P11A with the agreed
R R
translations at P10B and P11E). Admitted in evidence is which of the
S video files and photo files are the ten video files and the four photo files S

particularised in the charge.13 Also admitted is that these ten video files
C and four photo files are child pornography.14 C
D 24. From exhibit P5 a photograph album (exhibit P6) has been D
produced showing the image of each of the four photo files and a screen
E E
15
capture from each of the ten video files.
F F
25. I am satisfied so I am sure that child pornography was found
G G
on the computer. The finding of the child pornography on the computer
H is not sufficient to prove the defendant was in possession of that child H
pornography. As stated earlier the prosecution must prove the defendant
I I
had control of and knowledge of the video files and the photo files on the
J computer. J
K K
26. In determining whether the defendant was aware of the video
L
files and the photo files on the computer, the location where the video L
files and photo files were found; whether the files were ever viewed and
M M
how to access the files are relevant matters for consideration.
N N
Location of the child pornography
O O
27. The evidence of DSPC 23344 was that all the video files
P P
including the ten child pornography video files were found in C drive,

files were also found in the same folder. These are nos. 13, 14, 15, 16, 18
C & 20 of Annex A to the first statement of which nos. 13, 15, 16 & 20 are C
17
the 4 photo files subject of the charge.
D D
28. A first reading of paragraph 5 (ix) of DSPC 23344’s first
E E
statement (exhibit P10) gives the impression that suspected child
F pornography was found together with personal photographs of the suspect. F
The remaining seven photo files do not contain any child pornography or
G G
suspected child pornography. They are in different locations and are all
H personal photographs. The fact they were not found together with H
suspected child pornography should have been made clear at the
I I
beginning of the trial.
J J
Has the child pornography been viewed?

29. Annex A to both the first and second statements of DSPC L

23344 shows the time the video files and the photo files were last

accessed; created and last written together with the hash value of the files.
N These terms are explained by DSPC 23344 under the heading “Remark” N
19
after paragraph 9 in his second statement.
O O
30. From this data it can be seen that the ten video files were
P P
created between the 27 September and the 29 October 2008 except one
Q which was created on the 28 July 2009. The files were last written on the Q
same day they were created save for one which was last written the

September 2008 and last written and last accessed on the same day they
D D
were created.
E E
20
31. The Last Accessed Timestamp was disabled. DSPC 23344
F explained in court that because the Last Accessed Timestamp was F
disabled the last access time will not be changed if the video file is
G G
opened unless the video file is also saved at the same time. The last
H access times shown in Annexes A may not therefore be the last time the H
files were viewed.
I I
J 32. This is not however the only evidence that the video files J
were viewed. As part of his examination DSPC 23344 was specifically
K K
tasked to see whether the files had been opened by the computer user.21
L L
33. DSPC 23344 found sixteen Windows shortcut files which
M M
were linked to ten video files. The presence of the shortcut files show
N that the files had been opened by a video playing program. 22 Seven video N
files were opened by Real Player and three by another video playing
O O
program. In evidence DSPC 23344 said that he could not see which
P video playing program was opened to play these three video files. P
Q 34. Annex B1-B3 to the second statement lists out the ten video Q
files to which the sixteen shortcut files are linked alongside the time the
R R
shortcut files were last accessed; created and last written together with the

hash value of the shortcut files. 23 Except for video files 3 & 6 the

D 35. From this data it can be seen the shortcut files linked to the D
child pornography video files were created at various times between 28
E E
September 2008 and the 24 April 2013. The shortcut files were last
F accessed and last written on the same days between 1 June 2012 and the F
24 April 2013 except one shortcut link which was last accessed and last
G G
written on the 7 October 2008. DSPC 23344 explained in evidence that
H the disabling of the Last Accessed Timestamp did not affect the last H
access time of the shortcut files. The last access times shown in Annex
I I
B1-B3 are therefore the last times the files were viewed.
J J
Access to the child pornography
K K
L
36. The prosecution did not ask DSPC 23344 to demonstrate L
how the child pornography could be accessed, whether by following the
M M
full path or a shortcut. In order to fully understand DSPC 23344’s
N evidence I therefore asked DSPC 23344 where the child pornography was N
located and to demonstrate how a user of the computer would access the
O O
child pornography. DSPC 23344 first demonstrated how to access the
P files in “Download” from the full path: P
C\Users\user\Downloads\Foxy\Download and the shortcut files from the
Q Q
path C\Users\user\AppData\Roaming\Microsoft\Windows\Recent.

B B
37. In the Foxy folder there are two folders “Download” and
C “Temp”. When DSPC 23344 opened the folder “Download” the screen C
showed a list of 181 files. The names of all the suspected child
D D
pornography files could be seen, all of which DSPC 23344 believed had
E been downloaded through the Foxy application because they were in the E
folder under Foxy. In the folder “Recent” there are 150 files, including
F F
the shortcut files linked to the child pornography files. Again the names
G of all the suspected child pornography files could be seen. G
H 38. These two demonstrations were made by using the H
programme Encase Law Enforcement and not from the simulation of the
I I
computer (exhibit P5). The remainder of the demonstrations were from
J J
the simulation of the computer.25
K K
39. DSPC 23344 next demonstrated how to access the files by
L using the shortcut files as seen in Annex D to his second statement.26 L
Although DSPC 23344 said there was only one short cut file shown on
M M
Annex D both parties accept that there are in fact three shown, two of
N which are linked to the child pornography video files. 27 Access is by N
clicking the start menu on the simulation of the computer’s user home
O O
screen/desktop then documents (D) which opens up the box seen in
P 25 P
The fact that DSPC 23344 used two different ways to access what was on the computer became
apparent during the defendant’s evidence when I asked to be provided with the clone, exhibit P5
Q or a copy, so that I could repeat the demonstrations. Put simply from what the court was provided Q
I was unable to access 181 files from the full path C\Users\user\Downloads\Foxy\Download. By
using the simulation of the computer only 179 files could be accessed the display of which was
R different from that seen when DSPC 23344 used the programme Encase Law Enforcement. To R
try and ensure that the court was able to access the same as what DSPC 23344 demonstrated in
court this necessitated a number of adjournments. Finally after closing submissions had been
S S
adjourned twice the matter was fully explained with the provision of photographs “E”. I then
repeated in court all the demonstrations performed by DSPC 23344.

D 40. DSPC 23344 demonstrated access to all the files by right D
clicking the start menu on the simulation of the computer’s user home
E E
screen/desktop then file manager (X) from which the full path:
F C\Users\user\Downloads\Foxy\Download is reached. The “download” F
folder is opened showing the names of 179 files together with images of
G G
the photo files including the names of the child pornography files and the
H images of the four photo files as depicted in the photographs, exhibit P6. H
I I
41. DSPC 23344 also demonstrated an alternative way to access
J the files which had no shortcut file. This was by clicking “user” located J
on the top line of the box containing the shortcut files in Annex D. From
K K
the “user” folder the files can be accessed by following the path
L Downloads\Foxy\Download. Direct access to the “user” folder can also L
be made by clicking the “user” icon which is located in the top right
M M
hand corner of the home screen page/desktop (seen on Annex D). The

including the names of the child pornography files and the images of the
O O
four photo files as depicted in the photographs, exhibit P6.
P P
Real Player
Q Q
42. DSPC 23344 also demonstrated how to access the files
R R
directly from Real Player. Real Player is accessed by clicking the start
S menu on the simulation of the computer’s user home screen/desktop then S
programmes from where the Real Player programme can be opened. By
T T
clicking file (F) the box seen in Annex C is opened. No. 5 in the box is a

A A
B B
shortcut file which points directly to the video file entitled: “Rape
C Primary School Student”. This is one of the suspected child pornography C
video files found by DSPC 23344 but is not one of the ten video files
D D
subject of the charge.
E E
43. DSPC 23344 described the other suspected child
F pornography files not shown in Annex C as “hidden” and which needed F
to be looked for. Access is by clicking open (O) or Ctrl+O seen at the top
G G
of the box in Annex C then Browse (B). The path
H C\Users\user\Downloads\Foxy\Download is reached and the “download” H
folder opened. The names of the 179 files, including the names of the
I I
child pornography files and the images of the four photo files as depicted
J J
in the photographs, exhibit P6 are again shown.
K K
44. In cross-examination DSPC 23344 disagreed with Mr
L Boyton that a file can be opened and a shortcut created without the video L
being played. I therefore asked DSPC 23344 to demonstrate the playing
M M
of a video. DSPC 23344 selected one of the child pornography video
N files from the Foxy “download” folder. 28 By double clicking on the N
name of the file the video was automatically played by Real Player.
O O
DSPC 23344 then showed that shortcuts of the video file had been
P created which replaced shortcuts in both Annex C and Annex D. Earlier P
in evidence DSPC 23344 had explained that the number of shortcuts that
Q Q
could be shown in the box in Annex D was limited to fifteen.

C C
45. All the files having been found in the download folder of
D Foxy, mention should be made here of Foxy. Foxy is a peer to peer file D
sharing application which enables the user to share files stored on his
E E
computer with other Foxy users and to look for files shared by other Foxy
F users.29 During cross-examination DSPC 23344 confirmed that Foxy was F
installed on the computer however he did not check whether Foxy was
G G
working properly.
H H
“Files to be downloaded automatically is not an option for Foxy users”
I I
46. One of the tasks of DSPC 23344 was to see whether the
J J
Foxy application downloads files to the computer automatically without
K
the user’s knowledge.30 DSPC 23344 explained in evidence that the user K
L
had to select which files he wanted downloaded, including child L
pornography files, because files will not be downloaded automatically by
M M
Foxy.
N N
47. During further cross-examination arising from questions
O asked by the court Mr Boyton asked DSPC 23344 whether Foxy had a O
record of searches. DSPC 23344 replied there was and demonstrated this
P P
by accessing the Foxy programme direct from the Foxy icon seen on the

48. A photograph showing the search history was taken later and
C is attached to the written submission of Mr Boyton. The search history C
lists the key words used to search for a file from other Foxy users. DSPC
D D
23344 confirmed that in the search history there was no record of
E searches for child pornography. In further re-examination DSPC 23344 E
said that this search history can be cleared by clicking on the last line of
F F
the search history. To be noted here is that this is not a history of files
G viewed as subsequently submitted by Mr Boyton.32 G
H 49. DSPC 23344 also explained how to search for a file from H
other Foxy users.33 If the key words of the search resulted in any “hits” a
I I
list of files would appear. By selecting a file this would be downloaded
J J
onto Foxy. By clicking on the download icon (a globe) the name of the
K
file selected could be seen and the percentage of the file that had been K
downloaded. This was later photographed during the defendant’s
L L
evidence and marked “C”. DSPC 23344 disagreed with Mr Boyton that
M
the video file could be played at the same time as the file was being M
downloaded.
N N
50. Notwithstanding the child pornography files were all found
O O
in the download folder of Foxy the prosecution did not adduce in
P evidence whether the files could be accessed and viewed directly from P
Foxy without the need to go through C drive or the shortcuts. At the end
Q Q
of the questioning by Mr Boyton DSPC 23344 confirmed that the files

“Billy” would sometimes, until around 2014, stay overnight.
H H
I 54. Between 2005 and 2013 the defendant worked as a tour I
guide which required him to travel overseas. During this time the
J J
defendant would spend about one week per month in Hong Kong.
K K
55. The defendant bought the computer about 8-9 years ago for
L L
his own use and for use by his family members. On one occasion when
M
the defendant returned home from a tour he saw Billy playing on the M
computer. In cross-examination the defendant said this was between
N N
2008 and 2009. Anybody who came to the home could also play on the
O computer. O
P 56. Initially the computer was placed in the living room for P
everyone to use and was connected to a monitor and a router. The router
Q Q
was also connected to a modem in his younger sister’s bedroom to enable
R access to the internet. The defendant did not create any specific user R
accounts and no password was required to use the computer. The
S S
computer could therefore be turned on and used by anybody.

57. After purchasing the computer the defendant began to
C observe various problems, which in court have been described as C
breaking down; lost control; not working properly and malfunctioning.
D D
The defendant believing the computer had contracted some virus
E purchased the anti-virus software NOD 32 (exhibit D5) which he installed E
on the computer. In cross-examination the defendant said that it was
F F
around 2009 that he believed the computer had a virus.
G G
58. The installation of NOD 32 did not however solve the
H computer problems which in fact became worse. Family members told H
the defendant that sometimes they “lost control” of the computer.35
I I
J 59. Due to the need to go overseas the defendant seldom used J
the computer. When he did the defendant used the programme WinAmp
K K
to play videos. The defendant also used Foxy to look for videos as did
L his family members and Billy. The defendant said he rarely used the L
Windows shortcuts to look for videos and never used Real Player.

and the court to demonstrate how he accessed video files on the computer.

61. Around 2013 the computer was out of order and the
C defendant without consulting his family members placed the computer in C
his bedroom without any wires or cables attached. When Mr Boyton
D D
drew to the defendant’s attention that according to the data sheet prepared
E by DPC 4384,38 that the 25 April 2013 was the last time the computer E
was accessed, the defendant said this was approximately the time the
F F
computer was out of order. The computer was placed in the defendant’s
G bedroom because his family members used to put all things in his G
bedroom, including a “Hello Kitty” doll and clothes belonging to his
H H
parents as shown in photographs 12, 22 & 25, exhibit P7.
I I
62. After re-examination when the court referred to this evidence
J J
the defendant said he did not put the computer in his bedroom. The
K
defendant explained that because he was often out of Hong Kong his K
family members used his room as if it was a storage room. In 2013
L L
because the computer malfunctioned his family members said to him,
M
“How about we just put it in your room first or for the time being?” M
N 63. The defendant did not throw away the computer because he N
said he had some photographs and information on the computer from his
O O
previous tours. No replacement computer was bought for the family to
P use although the defendant had earlier bought a notebook computer for P
use in his work.

66. The evidence of DSPC 23344 is that sixteen Windows
I shortcut files were found linked to ten suspected child pornography video I
files. Seven of the video files were believed to have been opened by Real
J J
39
Player, six of which are child pornography.
K K
67. The defendant testified that he never used Real Player and
L L
that when experiencing problems with the computer Real Player would
M automatically pop-up. The defendant described two situations when Real M
Player popped up. First ‘subtitles’ would appear which the defendant
N N
could not read. In this situation the defendant said all he could do was
O click “OK”. O
P P
68. The second situation was that Real Player would freeze
Q saying that there was no response from the programme. As a result the Q
defendant would manually shut down Real Player by pressing
R R
alt/ctrl/delete and then switch off the computer. Later in evidence the
S defendant said that he manually shut down Real Player when the Real S
Player window popped up as shown in photograph, exhibit D6.

C police dramas the defendant replied he had watched one episode of C
“Cadre police on duty.” The defendant explained that his sister had told
D D
him that he could access the video from Foxy downloads. On drawing to
E the attention of the defendant that Annex D to the second statement of E
DSPC 23344 showed shortcut links to “Cadre police on duty” having
F F
been opened in Real Player, the defendant replied that Real Player was
G not working. 40 G
H 70. I have no hesitation in rejecting the defendant’s evidence that H
Real Player was not working. As already described DSPC 23344
I I
demonstrated in court the playing of one child pornography video by Real
J J
Player.41 If the demonstration given by DSPC 23344 is repeated nine of
K
the ten child pornography video files can be played on Real Player. K
Further as can be seen from Annex B to the second statement of DSPC
L L
23344,42 the video files were last accessed on Real Player in 2008, 2012
M
and 2013, showing that Real Player had been working for that period of M
time.

from the internet. In evidence-in-chief the defendant explained that after
Q Q
a video had been downloaded by Foxy he would open the video directly
R from the download section of Foxy shown in photograph “C”. The R
defendant said he did not look anywhere else for Foxy videos.

C how he accessed Foxy. The defendant demonstrated by first clicking on C
the Foxy icon seen on the toolbar on the simulation of the computer’s
D D
user home screen/desktop which opens the home page of Foxy. The
E home page of Foxy is shown in photograph “B”. E
F 73. To view a video file downloaded by Foxy the defendant F
would click on the download icon (a globe) on the home screen of Foxy.
G G
This opens a box showing a list of files downloaded by Foxy. The
H defendant said he downloaded these files. This is when photograph “C” H
was taken.
I I
J 74. All the files shown in photograph “C” are music files. When J
this was drawn to the attention of the defendant he repeated that when he
K K
downloaded videos he would view the video from the download icon.
L The defendant however was unable to say in which location the videos he L
had viewed were.
M M
N 75. All the videos can be found by clicking on the box “View N
downloaded folders”, which is seen above the list of files in photograph

O O
“C”. This opens the “download” folder of Foxy as shown in photograph
P “D”. The names of 179 files can be seen together with images of the P
photo files including the names of the child pornography files and the
Q Q
images of the four photo files as depicted in the photographs, exhibit P6.
R At my request a table was prepared setting out which of the 179 files are R
the child pornography files. This is annexed to the written submission of

DSPC 23344 demonstrated access to the files from the simulation of the

D 76. When the court asked the defendant if he ever browsed any D
files from “View downloaded folders” the defendant replied he did not
E E
and said that the files he wanted to view were in the box shown in
F photograph “C”. When asked how he viewed videos (the box showing F
only music files), the defendant replied that initially there were MTV
G G
video files shown in the box but he did not know why they were not there
H now. H
I I
77. The download folder of Foxy was then opened by clicking
J on “View downloaded folders”. The defendant agreed that pornographic J
images were shown. When asked if he had anything to say about what
K K
was shown the defendant replied that there were MTV video files and a
L lot of MP3 (music) files which belonged to him. When asked by the L
court if he wished to say anything as to why music videos and MP3 files
M M
belonging to him were found in the same folder as pornographic files the
N defendant replied “I have no idea”. N
O O
78. In re-examination the defendant said this was the first time
P he had seen what is shown in photograph “D” and that after he had P
watched a video he did not pay any more attention to the video. The
Q Q
defendant said that he only knew how to find a video from the download
R icon and that initially there would be a record of the video file he had R
viewed in the box seen in photograph “C”. When Mr Boyton asked how
S S
he would find a file no longer shown in the box the defendant replied that

D Q. So you make a fresh internet search, is that right? D
E E
A. Yes, because I don’t know how to click those buttons.
F F
79. I have no hesitation in rejecting the defendant’s evidence that
G he only accessed files, whether music or video, from clicking the G
download icon. I do not find credible the defendant never browsed any
H H
files from “View downloaded folders” which is on the very same page
I that the defendant says he accessed the download icon and made a search. I
Nor do I find credible that the defendant would do a fresh search if he
J J
wanted to play a video again because he did not know how to click the
K K
other buttons.
L L
80. I remind myself that the rejection of the defendant’s
M evidence is not determinative of the issues in the case. The defendant has M
to prove nothing. A case in which defence evidence is called and is not

beyond reasonable doubt.

I check whether there was any password to use the computer and said there I
was only one user account “User”, which was created by Microsoft and
J J

password protected. Anyone with access to the computer could therefore
L
use the computer by simply turning on the computer. L
M 87. As noted earlier the defendant said that his parents; younger M
sister and her boyfriend used the computer and that anyone who visited

their home could also use the computer.49 I find inherently improbable

88. Specifically regarding the father, in cross-examination the
C defendant said that his father was not very familiar with computers and C
that he was only a beginner, having started in 2011. In answer to the
D D
court, the defendant said he was not clear about whether his father used
E the computer prior to 2011. Also in answer to the court, the defendant E
said that his mother first started using the computer between 2008 and
F F
2009 before the problems with the computer started.
G G
89. On this evidence the father cannot have been responsible for
H downloading the child pornography in 2008 and 2009. Further I find H
inherently improbable that if the parents used the computer they would
I I
download child pornography on the computer used by their son, let alone
J J
leave the child pornography on the computer. Equally I find inherently
K
improbable that if the children used the same computer as their parents, K
they would download child pornography on the computer, let alone leave
L L
the child pornography on the computer for their parents to see. I reject
M
that the parents downloaded the child pornography. M
N 90. Similarly I find inherently improbable that if the boyfriend N
used the computer he would download child pornography on the
O O
computer used by his girlfriend. I reject the boyfriend downloaded the
P child pornography. I reject a visitor to the flat used the computer and P
secretly downloaded child pornography without anyone knowing.
Q Q
R 91. In answer to the court, the defendant said his younger sister R
had used the computer from the time the computer was purchased. There
S S
is some evidence in support that the sister had at some stage used the
T computer. When the computer was set up for the defendant to T
demonstrate how he accessed files on the computer, a series of pop-ups
U U
V V

A A
B B
were seen. One of these was Windows Live Messenger and is shown in
C photograph, exhibit D7. C
D 92. The defendant testified that the email address shown on the D
pop-up is that of his younger sister Leung Wing Yan. Notwithstanding
E E
the younger sister may have used the computer at some stage I find
F inherently improbable that she would download child pornography on the F
computer used by her brother and leave the child pornography on the
G G
computer for him to see unless she knew her brother also wished to view
H the pornography. H
I I
93. The only inference to draw from the finding of the child
J pornography on the computer owned by the defendant and found in his J
bedroom is that he was the only user of the computer after the child
K K
pornography was first downloaded on to the computer. I reject that
L anyone else was using the computer after that time. L
M M
94. If I am wrong and cannot reject that others may have used
N the computer and downloaded the child pornography the question to ask N
is does this stop the inference being drawn that the defendant was in
O O
possession of the child pornography?
P P
95. The prosecution do not have to show, as Mr Boyton submits,
Q that the defendant had exclusive control. In the Scottish case of Harris v Q
HM Advocate50, the defendant sought to incriminate his girlfriend for the
R R
presence of indecent photographs of children found on his computer. The

Similarly in HKSAR v Justin Yves Herbonnet Line J held that the fact
D D
others may have access to the computer did not stop the inference running.
E E
96. Therefore even if other family members used the computer
F and downloaded the child pornography I am nevertheless satisfied for the F
reasons set out earlier, in particular that the files had been on the
G G
computer since 2008 and 2009; were easily accessible from Foxy and that
H the names of the child pornography files and the images of the four photo H
files can be seen when accessing the files from Foxy, a programme which
I I
the defendant admits he used, that the only inference to draw is that the

defendant was aware of the files on his computer and was in control of

them. K

observe problems with the computer, variously described as breaking

system which was 2-3 years before he began to observe problems with

out after logging on; Real Player automatically popping up; the computer
E E
automatically connecting to the internet; and the speed of the computer
F getting slower and slower. F
G G
100. At the end of the first day the defendant gave evidence, I
H directed that the computer be set up the following morning. After cross- H
examination, Mr Boyton applied for leave to ask further questions about
I I
various pop-ups seen on the simulation of the computer’s user home
J screen/desktop when turning on the computer. J
K K
101. The defendant explained that when he experienced problems
L
with the computer he would see these pop-ups. Photographs were taken L
of the pop-ups and marked exhibits D6 & D7. When asked questions by
M M
the court a warning from Windows Security Centre popped up. This was
N photographed and marked “A”. N
O 102. Believing the computer had contracted a virus, the defendant O
purchased the antivirus software programme NOD 32 (exhibit D5) which
P P
he installed on the computer. Although in cross-examination the
Q defendant was unable to point to anything on the simulation of the Q
computer’s user home screen/desktop to show NOD 32 was installed,
R R
there is no doubt that NOD 32 was installed. In answer to the court, the
S defendant demonstrated by clicking on the start menu and going to S
programmes that NOD 32 was found by going to the programme Eset.
T T
Further during the demonstrations by the defendant, pop-ups were seen
U U
V V
33
A A
B B
which also clearly showed NOD 32 was installed. These pop-ups were
C not however photographed. C
D 103. After installation of NOD 32, warnings like exhibit D4 D
would automatically pop-up. When asked by Mr Boyton what he would
E E
do when a warning popped up, the defendant described three situations.
F First, the defendant would follow the direction of the warning and scan F
the computer to look for any virus or malicious programme. In cross-
G G
examination the defendant said that if any virus or malicious programme
H was found, these would be “quarantined”. When asked by the court what H
he understood by “quarantined”, the defendant replied just like going to
I I
hospital and then went on to say that when malicious software was found,
J J
he would opt to remove the file and not treat the file.
K K
104. Second, when browsing the internet, the user would be asked
L whether he wanted to continue or shut down the web page. Third, when L
using Foxy, the user would be informed that Foxy was trying to connect
M M
to the internet.
N N
105. The installation of NOD 32 did not however solve the
O O
computer problems which in fact became worse. Family members told
P the defendant that sometimes they “lost control” of the computer. When P
asked by the court whether there was anything that happened which
Q Q
resulted in the computer no longer being used, the defendant replied that
R when he last used the computer, he was unable to open the user home R
screen/desktop. The defendant said that if he remembered correctly he

last used the computer in the winter prior to April 2013.

C C
106. In cross-examination PC 4440 (PW2) agreed when he seized
D the computer that the computer was not turned on and was not connected D
to any cable or equipment. According to the data sheet prepared by DPC
E E
54
4384, the last time the computer was used was the 25 April 2013, which
F was about nine months prior to PC 4440 seizing the computer. F
G G
107. The fact the computer was not turned on and was not
H connected to any cable or equipment when seized from the defendant’s H
bedroom is consistent with the defendant’s evidence that he experienced
I I
problems with the computer, which led to him no longer using the
J computer. Nevertheless I have no hesitation in rejecting the defendant’s J
evidence that by April 2013 the computer was out of control and that
K K
when he last used the computer in the winter prior to April 2013, he could
L not access the user home screen/desktop. I do not find this evidence L
credible.

P working. Further all the child pornography files, which had been created P
in 2008 and 2009, had last been viewed between 2008 and 2013. Two

109. The submission that the child pornography files may have
C been downloaded by a virus is, in my view, nothing more than C
speculation. In cross-examination after DSPC 23344 agreed that he did
D D
not investigate whether there was any virus on the computer, Mr Boyton
E asked DSPC 23344 whether he checked to see if there were any “pop-up E
windows” as a result of malicious software. DSPC 23344 replied that
F F
this will not happen. I reject the appearance of the pop-up windows was
G because of a virus. G
H 110. Contrary to the written submission of Mr Boyton, at no time H
was it ever put or suggested to DSPC 23344 that the child pornography

found in the Foxy download folder was or may have been downloaded by
J
a virus.56 Apart from asking whether “pop-up windows” were as a result J
K
of malicious software, what Mr Boyton did was to show DSPC 23344 K
two information sheets prepared by the Information Technology Service
L L
Centre of The Chinese University of Hong Kong.
M M
111. DSPC 23344 was first referred to “Risks in Peer-to-Peer File
N Sharing” (exhibit D2). DSPC 23344 agreed the risks of file sharing set N
out in paragraph 2 A) and B) including that peer to peer software users
O O
can easily contract computer viruses and the software may also contain
P viruses and worms which prevent the computer from functioning properly. P
DSPC 23344 agreed that this would include slowing down of the
Q Q
computer and that freezing of the computer can occur. DSPC 23344
R again disagreed pop-up menus would appear because of a virus. R

§3 of Mr Boyton’s supplemental written submission.

A A
B B
112. The second paper was “Know more about Foxy” (exhibit
C D3). DSPC 23344 was referred to part IV, paragraph 3, “Infection of C
virus or worm”. DSPC 23344 agreed with the statement that if the
D D
computer was affected by virus or worm, the Foxy settings could be
E changed without notice to the user. E
F 113. DSPC 23344 had not heard of the two viruses mentioned in F
this part. With regard to the two effects of the virus PE_POLIP A, DSPC
G G
23344 agreed that the virus may consume a large amount of system
H resources and cause the computer to become noticeably sluggish. DSPC H
23344 said that it may be the case the virus may install malicious
I I
software to disable the security system, modify system files and install
J J
additional malware.
K K
114. The agreement by DSPC 23344 to these statements amounts
L to no more than agreeing the effects of a virus or a worm on the operation L
of a computer. The defendant’s belief that there was a virus is no more
M M
than a belief. I find that there is no evidence before the court that there
N was or may have been a virus on the computer. N
O O
115. Even if there was a virus on the computer there must be
P evidence before the court that the downloading of the child pornography P
was or may have been because of a virus. There is no evidence before the
Q Q
court that the child pornography was or may have been downloaded by a
R virus. I reject the submission the child pornography may have been R
downloaded by a virus.
S S
116. If I am wrong and cannot rule out that the child pornography
T T
may have been downloaded by a virus, the question to be asked again is,
U U
V V
37
A A
B B
does this stop the inference being drawn that the defendant was in
C possession of the child pornography? In my view the answer is also no. C
Even if the child pornography was downloaded by a virus I am
D D
nevertheless satisfied for the reasons set out earlier, in particular that the
E files were easily accessible from Foxy and that the names of the child E
pornography files and the images of the four photo files can be seen when
F F
accessing the files from Foxy, a programme which the defendant admits
G he used, that the only inference to draw is that the defendant was aware of G
the files on his computer and was in control of them.
H H
117. Having carefully considered all the evidence I find I am
I I
satisfied so that I am sure that the prosecution have proved beyond
J J
reasonable doubt the defendant was in possession of the child
K
pornography, the defendant having control of and knowledge of the K
existence of the video files and photo files on the computer.
L L
Statutory defence
M M
N 118. The prosecution having proved beyond reasonable doubt that N
the defendant was in possession of the child pornography, it is open for
O O
the defendant to rely on any of the defences in section 4(3) of the
P Ordinance. By saying he was not aware of the existence of the child P
pornography on the computer the defendant relies on the statutory
Q Q
defence in section 4(3)(c) of the Ordinance that he had not seen the child
R pornography and did not know nor suspect it to be child pornography. R
S 119. A defendant is taken to establish any fact that needs to be S
established for the purpose of a defence under subsection (3)(c) if (a)
T T
sufficient evidence is adduced to raise an issue with respect to the fact;
U U
V V
38
A A
B B
and (b) the contrary is not proved by the prosecution beyond reasonable
C doubt. C
D 120. In HKSAR v. Ng Po On57 Ribeiro PJ explained the nature of D
an evidential burden. He stated:58
E E
F
“An evidential burden stands in contrast to a reverse F
persuasive burden. It does not require the accused to establish
anything as a matter of proof. An evidential burden arises
G where the defendant wishes to put in issue some matter that is G
potentially exculpatory while the prosecution continues to bear
the persuasive burden throughout. In such cases, there must be
H H
evidence supporting such exculpatory matter which is
sufficiently substantial that it raises a reasonable doubt as to the
I defendant’s guilt. Unless such reasonable doubt is removed, the I
prosecution fails to prove its case. If, on the other hand, the
accused fails to adduce or point to any evidence on the relevant
J issue or if the evidence adduced is rejected or is not sufficiently J
substantial to raise a reasonable doubt, the potentially
K exculpatory matter places no obstacle in the way of the K
prosecution proving its case beyond reasonable doubt. An
evidential burden, functioning in this manner, is wholly
L consistent with the presumption of innocence.” L
M 121. Later in the judgment Ribeiro PJ went on to add:59 M
N “It must be emphasised that an evidential burden is not N
something nominal or illusory. It requires the defendant to
adduce or otherwise be able to rely on evidence which is
O sufficiently substantial to raise a reasonable doubt which the O
prosecution must negative if he is to be convicted.”
P P
In R v Lambert, Lord Hope of Craighead put this point as
follows:
Q Q
“If the evidential burden were to be so slight as to make no
R difference – if it were to be enough, for example, for the accused R
merely to mention the defence without adducing any evidence –
important practical considerations would suggest that in the

39
A A
B general interest of the community the burden would have to be a B
persuasive one. But an evidential burden is not to be thought of
C as a burden which is illusory. What the accused must do is put C
evidence before the court which, if believed, could be taken by a
reasonable jury to support his defence.” 60
D D
122. This passage was also quoted in HKSAR v Hung Chan Wa.61
E E
Stock JA giving the judgment of the court said that the burden may be
F discharged regardless of the quarter from which the evidence derives but F
is not discharged by the mere mouthing of words by an accused.
G G
H
123. Having rejected the defendant’s evidence that he was not H
aware of the existence of the child pornography I find that the defendant
I I
has failed to adduce sufficient evidence to raise an issue with respect to
J the fact that he had not seen the child pornography and did not know nor J
suspect it to be child pornography. Even on the defendant’s evidence that
K K
he believed the child pornography may have been downloaded by a virus
L and that family members also used the computer, I find that the defendant L
has failed to adduce sufficiently substantial evidence that raises a
M M
reasonable doubt that he had not seen the child pornography and did not
N know nor suspect it to be child pornography. N
O 124. Although the prosecution are not required to prove the O
defendant had viewed the child pornography, I have nevertheless
P P
considered whether the defendant viewed the child pornography. I am
Q Q
satisfied so I am sure on the evidence, in particular that the child
R
pornography had been on the computer since 2008 and 2009; was easily R

S It is a defence to possession of indecent photographs of a child contrary to section 160A of the S
Criminal Justice Act 1988 and section 52A of the Civic Government (Scotland) Act 1982 for the

T photograph and did not know, nor had any cause to suspect, it to be indecent. T

accessible from Foxy, a programme which the defendant admits he used,
C and the inherent improbability of other family members using the C
computer unless they too wanted to view the child pornography, that the
D D
only inference to draw is that the defendant did view the child
E pornography. E
F 125. In reaching my verdict I have carefully considered F
everything said by Mr Boyton both individually and collectively,
G G
including that none of the defendant’s personal files, photographs or
H documents were found in the same folder as the child pornography; 62 no H
files were deleted;63 and only a small quantity of pornography was found
I I
on the computer. Nothing said by Mr Boyton causes me to doubt the
J J
findings I have made. I am satisfied so I am sure there are no material
K
and significant discrepancies, improbabilities or omissions in the K
evidence, which cause me to doubt the findings I have made.
L L
126. I am satisfied so I am sure the prosecution have proved all
M M
the elements of charge 1 beyond reasonable doubt. The defendant is
N convicted of charge 1. N

in the defendant’s bedroom.64 The prosecution submit that the offence
C being one of strict liability the defendant has no defence to the charge.65 C
D 128. The defence case is that no licence was required because the D
radio-transceivers were not working. In addition the defence say that in
E E
2011 two of the radio-transceivers had been seized by the police and
F subsequently returned to the defendant. By returning the radio- F
transceivers the defendant believed that he would not be prosecuted for
G G
possessing them.
H H
Were the three radio-transceivers working?
I I
129. The three radio-transceivers were examined by Mr Lau Yat
J J
Fan, an assistant inspector of communications with the Communications
K K
Authority. There was no challenge to the expertise of Mr Lau who held a
L
higher diploma, a bachelor degree and a Master of Science in electrical L
engineering. Mr Lau had worked for the Authority since 1998 and had
M M
examined suspected radio apparatus for over seven years. I was satisfied
N Mr Lau was able to give expert evidence relating to the examination of N
apparatus for radiocommunications.
O O
130. Mr Lau testified that in layman terms the three radio-
P P
transceivers were walkie-talkies. All three were operable and worked
Q normally and were able to transmit and receive broadcast words. In Q
answer to the court Mr Lau said that the three radio-transceivers were
R R
apparatus for transmission by radio waves.

131. In cross-examination Mr Lau disagreed that when he
C received all three radio-transceivers they did not have batteries. Mr Lau C
said exhibit P4 had a battery and pointed out to the court the battery
D D
which was attached to the bottom of the radio-transceiver. Mr Lau
E confirmed that he was asked to examine a total of four radio-transceivers E
one of which he did not classify as communications apparatus because
F F
the radio-transceiver was not working. Mr Lau disagreed P2, P3 and P4
G were also not functioning. G
H Defence evidence H
I I
132. In summary the defendant testified that the three radio-
J transceivers were purchased for photo taking during war games. Two J
were purchased from Yahoo (exhibits P2 & P3) and one from Apliu
K K
Street in Sham Shui Po (exhibit P4). The defendant had never used the
L three radio-transceivers and had no idea if they were functional or not. L
M M
133. Two of the three radio-transceivers (exhibits P2 & P3) had
N been seized by the police in 2011 and later returned to the defendant as N
evidenced by the “Receipt of Property Return” (exhibit D1). The police
O O
told the defendant that they had been examined by an expert and that
P there was no problem with them. The defendant accordingly felt that P
there was no problem with him possessing the radio-transceivers and that
Q Q
he would not be prosecuted for possessing them.
R R
Consideration of the evidence
S S
134. I have no hesitation in rejecting the defendant’s evidence that
T T
he had never used the three radio-transceivers and had no idea if they
U U
V V
43
A A
B B
were functional or not. I do not find this evidence credible. In cross-
C examination when put he knew they were in fact radio transmitters the C
defendant agreed and added, for the first time, that he knew they were not
D D
functional when he bought them.
E E
135. When the court clarified with the defendant his evidence as
F to whether he knew the radio-transceivers were functional, the defendant F
replied that when he bought the radio-transceivers he really did not know
G G
whether they were functional or not. When asked why he said in cross-
H examination he knew they were not functional the defendant replied he H
was told by the seller that they were not functional.
I I
J 136. I accept the expert evidence of Mr Lau. Mr Lau examined J
four radio-transceivers one of which he found was not working. I am
K K
satisfied that if any of the three radio-transceivers were not working Mr
L Lau would also have said they were not working. L
M M
137. I am satisfied so I am sure that the three radio-transceivers
N fall within the definition in the Ordinance of radiocommunications N
transmitting apparatus for which a licence is required.

Strict liability
P P
Q 138. At the commencement of the trial Mr Tracy said the offence Q
was not one of strict liability. However, in closing submission Mr Tracy,
R R
relying on the decision in HKSAR v Uniglobe Telecom (Far East)
S Ltd,66submits the offence is one of strict liability. 67 Mr Boyton’s position S

U U
V V
44
A A
B B
from the beginning has been that the offence, being a licensing matter, is
C one of strict liability. C
D 139. The Court of Appeal in Uniglobe held that the offences of D
maintaining a means of telecommunication without a licence and using
E E
radio communication apparatus without a licence were offences of strict
F liability. On appeal to the Court of Final Appeal the court in dismissing F
an appeal against conviction for maintaining a means of
G G
telecommunication without a licence confirmed that the offence was one
H of strict liability.68 In allowing the appeal against conviction for using H
radio communication apparatus without a licence the Court of Final
I I
Appeal did not consider whether the offence was also one of strict
J J
liability.
K K
140. Using radio communication apparatus without a licence is an
L offence contrary to section 8(1)(b) of the Telecommunications Ordinance, L
the same subsection under which the defendant is charged with
M M
possessing radiocommunication apparatus without a licence.
N N
141. The Court of Appeal did not consider whether the offence of
O O
possession was also one of strict liability. Whether an offence is one of
P strict liability is to be determined in accordance with the principles P
established in Hin Lin Yee & another v HKSAR,69 and Kulemesin Yuriy &
Q Q
another v HKSAR.70 As both parties agree the offence is one of strict
R liability I have not been addressed on this issue and therefore which of R
the five alternatives apply to possession.

A A
B B
142. In the circumstances I proceed on the same basis as the Court
C of Final Appeal in Uniglobe, that the offence is one of strict liability in C
that the prosecution do not have to prove guilty knowledge, but that it is a
D D
defence for the accused to prove, on a balance of probabilities, that he
E honestly held upon reasonable grounds, a belief in the existence of facts E
which, if true, would make his conduct innocent.71
F F
143. I have grave reservations that the police, when returning the
G G
two radio-transceivers, would have told the defendant that they had been
H examined by an expert and that there was no problem with them. From H
the “Receipt of Property Return” the officers returning the property were
I I
from the Property Office and not officers involved in the investigation
J J
arising from the seizure of the radio-transceivers.
K K
144. The fact remains, however, that the prosecution have not
L sought to adduce any evidence in rebuttal as to what the defendant was L
told; why the radio-transceivers were seized in the first place and the
M M
reason for their return. Whatever the defendant was told I am satisfied,
N on the evidence, that by returning the radio-transceivers the defendant N
honestly held upon reasonable grounds that he would not be prosecuted.
O O
This belief in my view also extends to the possession of the third radio-
P transceiver. P
Q Q
145. The defendant is acquitted of charge 2.

N 1. The defendant pleads not guilty to one charge of possession N
of child pornography, contrary to section 3(3) of the Prevention of Child
O O
Pornography Ordinance 1 (charge 1), and one charge of possession of
P apparatus for radiocommunications without a licence, contrary to section P

Introduction
C C
2. In summary on the evening of the 29th January 2014 the
D police executed a search warrant at Flat D, 9/F, Lok Moon Mansion, 29- D
31 Queen’s Road East in Wan Chai, where the defendant resided together
E E
with his parents and younger sister.
F F
3. The police seized from the defendant’s bedroom a white
G G
desktop computer (“the computer”) and three radio-transceivers.
H Subsequent forensic examination of the computer by DSPC 23344 of the H
Technology Crime Division revealed that sixteen video files and thirteen
I I
photo files suspected to be child pornography were stored on the
J computer. Ten of the video files and four of the photo files are the J
subject of charge 1. The photo files were originally referred to in the
K K
charge as four photo images. This was later amended to read four still
L films. I will in my verdict refer to these as photo files the term used by L
DSPC 23344.
M M
N 4. The three radio-transceivers were examined by Mr Lau Yat N
Fan, an assistant inspector of communications with the Communications
O O
Authority, who found them to be apparatus for radiocommunications, for
P which a licence is required. P
Q Evidence Q
R R
5. The prosecution called three witnesses referred to in the
S opening, namely: PC 4440 (PW2), who seized the computer and the three S
radio-transceivers and drew a sketch of the flat (exhibit P9); DSPC 23344
T T
(PW4) and Mr Lau Yat Fan (PW6).

6. Facts have been admitted pursuant to section 65C of the
C Criminal Procedure Ordinance3 (exhibits P8, P8A, P8B & P8C). I will C
refer to the admitted facts as I review the evidence.
D D
7. The defendant elected to give evidence. No witnesses were
E E
called on his behalf. Admitted in evidence is that the defendant has no
F criminal convictions.4 I direct myself as to good character in accordance F
with the decision in HKSAR v Tang Siu Man5.
G G
H 8. In reaching my verdict I remind myself of the burden and H
standard of proof and that the burden is on the prosecution throughout.
I I
The defendant has to prove nothing. I direct myself that I must be sure of
J the defendant’s guilt on each charge, each charge being considered J
separately. On the other hand if the court thinks that the defence
K K
evidence pointing to innocence is true or may be true, it would follow that
L the defence has raised sufficient doubt in the prosecution case and the L
defendant entitled to be acquitted.
M M
N 9. I remind myself that when drawing inferences from the N
evidence the inference must be the only reasonable inference to draw
O O
from the proved facts. If from the facts proved there is a reasonable
P inference to draw against the defendant as well as one in his favour the P
adverse inference cannot be drawn.

B B
very strong terms, more than once, my view as to Mr Tracy’s submission
C on charge 1. I do not propose to repeat those criticisms here. C
D Charge 1 - Possession of child pornography D
E E
11. On a charge under section 3(3) of the Ordinance the
F prosecution must prove beyond reasonable doubt that the defendant was F
in possession of the child pornography. This involves the prosecution
G G
proving that the defendant had control of and knowledge of the existence
H of the video files and photo files on the computer but not that the H
defendant knew they were child pornography (see HKSAR v Justin Yves
I I
Herbonnet6; Atkins v DPP 7 and McMurdo v HM Advocate8).
J J
12. Save that the computer was found in the defendant’s
K K
bedroom the prosecution opening does not say on what evidence the
L
prosecution rely upon to prove that the defendant was aware of the video L
files and photo files on the computer. The opening simply states the
M M
seizing of the computer and the finding of the child pornography on the
N computer. N

13. When asked by the court what evidence the prosecution will
C seek to adduce with regards to knowledge Mr Tracy recognizing that C
knowledge was the issue in the case stated that the court would be asked
D D
to infer knowledge from the circumstances of the finding of the computer;
E the admissions to be made by the defendant that he was the owner and in E
possession of the computer on the material day; and the evidence of
F F
DSPC 23344.
G G
14. The defence case in summary is that the defendant was not
H aware that the video files and the photo files were on his computer. The H
defendant says that he believed there was a virus on the computer and
I I
therefore the child pornography may have been downloaded by the virus.
J J
The defendant also says that the computer was used by his parents,
K
younger sister and her boyfriend and anyone else who visited the home. K
The defence contend therefore that the defendant was not in exclusive
L L
control of the computer and thereby implying other users of the computer
M
may have downloaded the child pornography without the knowledge of M
the defendant.
N N
15. If the defendant was not aware that the video files and the
O O
photo files were on his computer is true or may be true the defendant is
P entitled to be acquitted (see Atkins v DPP). 9 If the prosecution prove P
beyond reasonable doubt that the defendant was in possession of the child
Q Q
pornography the defendant may rely on any of the statutory defences set
R out in section 4 of the Ordinance. R

it to be child pornography.10

Prosecution evidence
F F
17. I now turn to consider the evidence. The principal evidence
G G
adduced by the prosecution is that of DSPC 23344 Tsang Nung Keung.
H DSPC 23344 retired in June this year. In my verdict I will refer to Mr H
Tsang as DSPC 23344. Three statements of DSPC 23344 have been read
I I
pursuant to section 65B of the Criminal Procedure Ordinance11 (exhibits
J P10, P11 & P12) and adopted as part of his evidence-in-chief. J
K K
18. There was no challenge to the expertise of DSPC 23344.
L
DSPC 23344 had worked in the Technology Crime Division since L
September 2005 and held various qualifications in computing. I was
M M
satisfied DSPC 23344 was able to give expert evidence on computer
N forensic examination. N
O 19. DSPC 23344 examined the hard disc of the computer and O
found the child pornography subject of the charge. In evidence DSPC
P P
23344 said he conducted the examination with the forensic programme
Q Encase. After examining the hard disc DSPC 23344 restored the hard Q
disc contents to one “Western Digital” external USB hard disc, exhibit P5.

E E
both during and at the end of the evidence of DSPC 23344 including
F asking DSPC 23344 to demonstrate how the user of the computer could F

H 21. Unless otherwise stated I accept the expert evidence of H
DSPC 23344. I do not propose to set out here a detailed summary of the

expert evidence. I will refer to the relevant parts when reviewing the
J evidence. J
K K
Finding of the child pornography
L L
22. The finding of the child pornography on the computer has
M not been challenged and can therefore be briefly stated. DSPC 23344 M
found on the hard disc of the computer sixteen video files of suspected
N N
child pornography and thirteen photo files of suspected child
O pornography and personal photographs of suspect (see paragraph 5 of O
both the first and second statements of DSPC 23344, exhibits P10 & P11).

25. I am satisfied so I am sure that child pornography was found
G G
on the computer. The finding of the child pornography on the computer
H is not sufficient to prove the defendant was in possession of that child H
pornography. As stated earlier the prosecution must prove the defendant
I I
had control of and knowledge of the video files and the photo files on the
J computer. J
K K
26. In determining whether the defendant was aware of the video
L
files and the photo files on the computer, the location where the video L
files and photo files were found; whether the files were ever viewed and
M M
how to access the files are relevant matters for consideration.

28. A first reading of paragraph 5 (ix) of DSPC 23344’s first
E E
statement (exhibit P10) gives the impression that suspected child
F pornography was found together with personal photographs of the suspect. F
The remaining seven photo files do not contain any child pornography or
G G
suspected child pornography. They are in different locations and are all
H personal photographs. The fact they were not found together with H
suspected child pornography should have been made clear at the
I I
beginning of the trial.

31. The Last Accessed Timestamp was disabled. DSPC 23344
F explained in court that because the Last Accessed Timestamp was F
disabled the last access time will not be changed if the video file is
G G
opened unless the video file is also saved at the same time. The last
H access times shown in Annexes A may not therefore be the last time the H
files were viewed.
I I
J 32. This is not however the only evidence that the video files J
were viewed. As part of his examination DSPC 23344 was specifically
K K
tasked to see whether the files had been opened by the computer user.21
L L
33. DSPC 23344 found sixteen Windows shortcut files which
M M
were linked to ten video files. The presence of the shortcut files show
N that the files had been opened by a video playing program. 22 Seven video N
files were opened by Real Player and three by another video playing
O O
program. In evidence DSPC 23344 said that he could not see which
P video playing program was opened to play these three video files. P

child pornography video files were created at various times between 28
E E
September 2008 and the 24 April 2013. The shortcut files were last
F accessed and last written on the same days between 1 June 2012 and the F
24 April 2013 except one shortcut link which was last accessed and last
G G
written on the 7 October 2008. DSPC 23344 explained in evidence that
H the disabling of the Last Accessed Timestamp did not affect the last H
access time of the shortcut files. The last access times shown in Annex
I I
B1-B3 are therefore the last times the files were viewed.

Access to the child pornography
K K
L
36. The prosecution did not ask DSPC 23344 to demonstrate L
how the child pornography could be accessed, whether by following the
M M
full path or a shortcut. In order to fully understand DSPC 23344’s
N evidence I therefore asked DSPC 23344 where the child pornography was N
located and to demonstrate how a user of the computer would access the
O O
child pornography. DSPC 23344 first demonstrated how to access the
P files in “Download” from the full path: P
C\Users\user\Downloads\Foxy\Download and the shortcut files from the
Q Q
path C\Users\user\AppData\Roaming\Microsoft\Windows\Recent.

37. In the Foxy folder there are two folders “Download” and
C “Temp”. When DSPC 23344 opened the folder “Download” the screen C
showed a list of 181 files. The names of all the suspected child
D D
pornography files could be seen, all of which DSPC 23344 believed had
E been downloaded through the Foxy application because they were in the E
folder under Foxy. In the folder “Recent” there are 150 files, including
F F
the shortcut files linked to the child pornography files. Again the names
G of all the suspected child pornography files could be seen. G
H 38. These two demonstrations were made by using the H
programme Encase Law Enforcement and not from the simulation of the
I I
computer (exhibit P5). The remainder of the demonstrations were from
J J
the simulation of the computer.25
K K
39. DSPC 23344 next demonstrated how to access the files by
L using the shortcut files as seen in Annex D to his second statement.26 L
Although DSPC 23344 said there was only one short cut file shown on
M M
Annex D both parties accept that there are in fact three shown, two of
N which are linked to the child pornography video files. 27 Access is by N
clicking the start menu on the simulation of the computer’s user home
O O
screen/desktop then documents (D) which opens up the box seen in
P 25 P
The fact that DSPC 23344 used two different ways to access what was on the computer became
apparent during the defendant’s evidence when I asked to be provided with the clone, exhibit P5
Q or a copy, so that I could repeat the demonstrations. Put simply from what the court was provided Q
I was unable to access 181 files from the full path C\Users\user\Downloads\Foxy\Download. By
using the simulation of the computer only 179 files could be accessed the display of which was
R different from that seen when DSPC 23344 used the programme Encase Law Enforcement. To R
try and ensure that the court was able to access the same as what DSPC 23344 demonstrated in
court this necessitated a number of adjournments. Finally after closing submissions had been
S S
adjourned twice the matter was fully explained with the provision of photographs “E”. I then
repeated in court all the demonstrations performed by DSPC 23344.

clicking the start menu on the simulation of the computer’s user home
E E
screen/desktop then file manager (X) from which the full path:
F C\Users\user\Downloads\Foxy\Download is reached. The “download” F
folder is opened showing the names of 179 files together with images of
G G
the photo files including the names of the child pornography files and the
H images of the four photo files as depicted in the photographs, exhibit P6. H
I I
41. DSPC 23344 also demonstrated an alternative way to access
J the files which had no shortcut file. This was by clicking “user” located J
on the top line of the box containing the shortcut files in Annex D. From
K K
the “user” folder the files can be accessed by following the path
L Downloads\Foxy\Download. Direct access to the “user” folder can also L
be made by clicking the “user” icon which is located in the top right
M M

including the names of the child pornography files and the images of the

four photo files as depicted in the photographs, exhibit P6.

Real Player
Q Q
42. DSPC 23344 also demonstrated how to access the files
R R
directly from Real Player. Real Player is accessed by clicking the start
S menu on the simulation of the computer’s user home screen/desktop then S
programmes from where the Real Player programme can be opened. By
T T
clicking file (F) the box seen in Annex C is opened. No. 5 in the box is a

A A
B B
shortcut file which points directly to the video file entitled: “Rape
C Primary School Student”. This is one of the suspected child pornography C
video files found by DSPC 23344 but is not one of the ten video files
D D
subject of the charge.
E E
43. DSPC 23344 described the other suspected child
F pornography files not shown in Annex C as “hidden” and which needed F
to be looked for. Access is by clicking open (O) or Ctrl+O seen at the top
G G
of the box in Annex C then Browse (B). The path
H C\Users\user\Downloads\Foxy\Download is reached and the “download” H
folder opened. The names of the 179 files, including the names of the
I I
child pornography files and the images of the four photo files as depicted
J J
in the photographs, exhibit P6 are again shown.
K K
44. In cross-examination DSPC 23344 disagreed with Mr
L Boyton that a file can be opened and a shortcut created without the video L
being played. I therefore asked DSPC 23344 to demonstrate the playing
M M
of a video. DSPC 23344 selected one of the child pornography video
N files from the Foxy “download” folder. 28 By double clicking on the N
name of the file the video was automatically played by Real Player.
O O
DSPC 23344 then showed that shortcuts of the video file had been
P created which replaced shortcuts in both Annex C and Annex D. Earlier P
in evidence DSPC 23344 had explained that the number of shortcuts that

could be shown in the box in Annex D was limited to fifteen.

45. All the files having been found in the download folder of
D Foxy, mention should be made here of Foxy. Foxy is a peer to peer file D
sharing application which enables the user to share files stored on his
E E
computer with other Foxy users and to look for files shared by other Foxy
F users.29 During cross-examination DSPC 23344 confirmed that Foxy was F
installed on the computer however he did not check whether Foxy was
G G
working properly.
H H
“Files to be downloaded automatically is not an option for Foxy users”
I I
46. One of the tasks of DSPC 23344 was to see whether the
J J
Foxy application downloads files to the computer automatically without
K
the user’s knowledge.30 DSPC 23344 explained in evidence that the user K
L
had to select which files he wanted downloaded, including child L
pornography files, because files will not be downloaded automatically by
M M
Foxy.
N N
47. During further cross-examination arising from questions
O asked by the court Mr Boyton asked DSPC 23344 whether Foxy had a O
record of searches. DSPC 23344 replied there was and demonstrated this
P P
by accessing the Foxy programme direct from the Foxy icon seen on the

48. A photograph showing the search history was taken later and
C is attached to the written submission of Mr Boyton. The search history C
lists the key words used to search for a file from other Foxy users. DSPC
D D
23344 confirmed that in the search history there was no record of
E searches for child pornography. In further re-examination DSPC 23344 E
said that this search history can be cleared by clicking on the last line of
F F
the search history. To be noted here is that this is not a history of files
G viewed as subsequently submitted by Mr Boyton.32 G
H 49. DSPC 23344 also explained how to search for a file from H
other Foxy users.33 If the key words of the search resulted in any “hits” a
I I
list of files would appear. By selecting a file this would be downloaded
J J
onto Foxy. By clicking on the download icon (a globe) the name of the
K
file selected could be seen and the percentage of the file that had been K
downloaded. This was later photographed during the defendant’s
L L
evidence and marked “C”. DSPC 23344 disagreed with Mr Boyton that
M
the video file could be played at the same time as the file was being M
downloaded.
N N
50. Notwithstanding the child pornography files were all found
O O
in the download folder of Foxy the prosecution did not adduce in
P evidence whether the files could be accessed and viewed directly from P
Foxy without the need to go through C drive or the shortcuts. At the end
Q Q
of the questioning by Mr Boyton DSPC 23344 confirmed that the files

53. In summary the defendant testified that he lived at home
G with his parents and younger sister, Leung Wing Yan, whose boyfriend G
“Billy” would sometimes, until around 2014, stay overnight.
H H
I 54. Between 2005 and 2013 the defendant worked as a tour I
guide which required him to travel overseas. During this time the
J J
defendant would spend about one week per month in Hong Kong.
K K
55. The defendant bought the computer about 8-9 years ago for
L L
his own use and for use by his family members. On one occasion when
M
the defendant returned home from a tour he saw Billy playing on the M
computer. In cross-examination the defendant said this was between
N N
2008 and 2009. Anybody who came to the home could also play on the
O computer. O
P 56. Initially the computer was placed in the living room for P
everyone to use and was connected to a monitor and a router. The router
Q Q
was also connected to a modem in his younger sister’s bedroom to enable
R access to the internet. The defendant did not create any specific user R
accounts and no password was required to use the computer. The
S S
computer could therefore be turned on and used by anybody.

C observe various problems, which in court have been described as C
breaking down; lost control; not working properly and malfunctioning.
D D
The defendant believing the computer had contracted some virus
E purchased the anti-virus software NOD 32 (exhibit D5) which he installed E
on the computer. In cross-examination the defendant said that it was
F F
around 2009 that he believed the computer had a virus.
G G
58. The installation of NOD 32 did not however solve the
H computer problems which in fact became worse. Family members told H
the defendant that sometimes they “lost control” of the computer.35
I I
J 59. Due to the need to go overseas the defendant seldom used J
the computer. When he did the defendant used the programme WinAmp
K K
to play videos. The defendant also used Foxy to look for videos as did
L his family members and Billy. The defendant said he rarely used the L
Windows shortcuts to look for videos and never used Real Player.

61. Around 2013 the computer was out of order and the
C defendant without consulting his family members placed the computer in C
his bedroom without any wires or cables attached. When Mr Boyton
D D
drew to the defendant’s attention that according to the data sheet prepared
E by DPC 4384,38 that the 25 April 2013 was the last time the computer E
was accessed, the defendant said this was approximately the time the
F F
computer was out of order. The computer was placed in the defendant’s
G bedroom because his family members used to put all things in his G
bedroom, including a “Hello Kitty” doll and clothes belonging to his
H H
parents as shown in photographs 12, 22 & 25, exhibit P7.
I I
62. After re-examination when the court referred to this evidence
J J
the defendant said he did not put the computer in his bedroom. The
K
defendant explained that because he was often out of Hong Kong his K
family members used his room as if it was a storage room. In 2013
L L
because the computer malfunctioned his family members said to him,
M
“How about we just put it in your room first or for the time being?” M
N 63. The defendant did not throw away the computer because he N
said he had some photographs and information on the computer from his
O O
previous tours. No replacement computer was bought for the family to
P use although the defendant had earlier bought a notebook computer for P
use in his work.

F and Foxy. F
G G
Real Player
H H
66. The evidence of DSPC 23344 is that sixteen Windows
I shortcut files were found linked to ten suspected child pornography video I
files. Seven of the video files were believed to have been opened by Real
J J
39
Player, six of which are child pornography.
K K
67. The defendant testified that he never used Real Player and
L L
that when experiencing problems with the computer Real Player would
M automatically pop-up. The defendant described two situations when Real M
Player popped up. First ‘subtitles’ would appear which the defendant
N N
could not read. In this situation the defendant said all he could do was
O click “OK”. O
P P
68. The second situation was that Real Player would freeze
Q saying that there was no response from the programme. As a result the Q
defendant would manually shut down Real Player by pressing
R R
alt/ctrl/delete and then switch off the computer. Later in evidence the
S defendant said that he manually shut down Real Player when the Real S
Player window popped up as shown in photograph, exhibit D6.

C police dramas the defendant replied he had watched one episode of C
“Cadre police on duty.” The defendant explained that his sister had told

him that he could access the video from Foxy downloads. On drawing to
E the attention of the defendant that Annex D to the second statement of E
DSPC 23344 showed shortcut links to “Cadre police on duty” having
F F
been opened in Real Player, the defendant replied that Real Player was
G not working. 40 G
H 70. I have no hesitation in rejecting the defendant’s evidence that H
Real Player was not working. As already described DSPC 23344
I I
demonstrated in court the playing of one child pornography video by Real
J J
Player.41 If the demonstration given by DSPC 23344 is repeated nine of
K
the ten child pornography video files can be played on Real Player. K
Further as can be seen from Annex B to the second statement of DSPC
L L
23344,42 the video files were last accessed on Real Player in 2008, 2012
M
and 2013, showing that Real Player had been working for that period of M
time.

the Foxy icon seen on the toolbar on the simulation of the computer’s

user home screen/desktop which opens the home page of Foxy. The
E home page of Foxy is shown in photograph “B”. E
F 73. To view a video file downloaded by Foxy the defendant F
would click on the download icon (a globe) on the home screen of Foxy.

J 74. All the files shown in photograph “C” are music files. When J
this was drawn to the attention of the defendant he repeated that when he
K K

L The defendant however was unable to say in which location the videos he L
had viewed were.

files from “View downloaded folders” the defendant replied he did not
E E
and said that the files he wanted to view were in the box shown in
F photograph “C”. When asked how he viewed videos (the box showing F
only music files), the defendant replied that initially there were MTV
G G
video files shown in the box but he did not know why they were not there
H now. H
I I
77. The download folder of Foxy was then opened by clicking
J on “View downloaded folders”. The defendant agreed that pornographic J
images were shown. When asked if he had anything to say about what
K K
was shown the defendant replied that there were MTV video files and a
L lot of MP3 (music) files which belonged to him. When asked by the L
court if he wished to say anything as to why music videos and MP3 files
M M
belonging to him were found in the same folder as pornographic files the
N defendant replied “I have no idea”. N
O O
78. In re-examination the defendant said this was the first time
P he had seen what is shown in photograph “D” and that after he had P
watched a video he did not pay any more attention to the video. The
Q Q
defendant said that he only knew how to find a video from the download
R icon and that initially there would be a record of the video file he had R
viewed in the box seen in photograph “C”. When Mr Boyton asked how
S S
he would find a file no longer shown in the box the defendant replied that

D Q. So you make a fresh internet search, is that right? D
E E
A. Yes, because I don’t know how to click those buttons.
F F
79. I have no hesitation in rejecting the defendant’s evidence that
G he only accessed files, whether music or video, from clicking the G
download icon. I do not find credible the defendant never browsed any
H H
files from “View downloaded folders” which is on the very same page
I that the defendant says he accessed the download icon and made a search. I
Nor do I find credible that the defendant would do a fresh search if he
J J
wanted to play a video again because he did not know how to click the
K K
other buttons.
L L
80. I remind myself that the rejection of the defendant’s
M evidence is not determinative of the issues in the case. The defendant has M
to prove nothing. A case in which defence evidence is called and is not
N N
believed is no different from one in which no evidence is called. In either

beyond reasonable doubt.

I check whether there was any password to use the computer and said there I
was only one user account “User”, which was created by Microsoft and

use the computer by simply turning on the computer. L
M 87. As noted earlier the defendant said that his parents; younger M

88. Specifically regarding the father, in cross-examination the
C defendant said that his father was not very familiar with computers and C
that he was only a beginner, having started in 2011. In answer to the
D D
court, the defendant said he was not clear about whether his father used
E the computer prior to 2011. Also in answer to the court, the defendant E
said that his mother first started using the computer between 2008 and
F F
2009 before the problems with the computer started.
G G
89. On this evidence the father cannot have been responsible for
H downloading the child pornography in 2008 and 2009. Further I find H
inherently improbable that if the parents used the computer they would
I I
download child pornography on the computer used by their son, let alone
J J
leave the child pornography on the computer. Equally I find inherently
K
improbable that if the children used the same computer as their parents, K
they would download child pornography on the computer, let alone leave
L L
the child pornography on the computer for their parents to see. I reject
M
that the parents downloaded the child pornography. M
N 90. Similarly I find inherently improbable that if the boyfriend N
used the computer he would download child pornography on the
O O
computer used by his girlfriend. I reject the boyfriend downloaded the
P child pornography. I reject a visitor to the flat used the computer and P
secretly downloaded child pornography without anyone knowing.
Q Q
R 91. In answer to the court, the defendant said his younger sister R
had used the computer from the time the computer was purchased. There
S S
is some evidence in support that the sister had at some stage used the
T computer. When the computer was set up for the defendant to T
demonstrate how he accessed files on the computer, a series of pop-ups
U U
V V
30
A A
B B
were seen. One of these was Windows Live Messenger and is shown in
C photograph, exhibit D7. C
D 92. The defendant testified that the email address shown on the D
pop-up is that of his younger sister Leung Wing Yan. Notwithstanding
E E
the younger sister may have used the computer at some stage I find
F inherently improbable that she would download child pornography on the F
computer used by her brother and leave the child pornography on the
G G
computer for him to see unless she knew her brother also wished to view
H the pornography. H
I I
93. The only inference to draw from the finding of the child
J pornography on the computer owned by the defendant and found in his J
bedroom is that he was the only user of the computer after the child
K K
pornography was first downloaded on to the computer. I reject that
L anyone else was using the computer after that time. L
M M
94. If I am wrong and cannot reject that others may have used
N the computer and downloaded the child pornography the question to ask N
is does this stop the inference being drawn that the defendant was in
O O
possession of the child pornography?
P P
95. The prosecution do not have to show, as Mr Boyton submits,
Q that the defendant had exclusive control. In the Scottish case of Harris v Q
HM Advocate50, the defendant sought to incriminate his girlfriend for the
R R
presence of indecent photographs of children found on his computer. The

Similarly in HKSAR v Justin Yves Herbonnet Line J held that the fact

others may have access to the computer did not stop the inference running.
E E
96. Therefore even if other family members used the computer
F and downloaded the child pornography I am nevertheless satisfied for the F
reasons set out earlier, in particular that the files had been on the
G G
computer since 2008 and 2009; were easily accessible from Foxy and that
H the names of the child pornography files and the images of the four photo H
files can be seen when accessing the files from Foxy, a programme which

the defendant admits he used, that the only inference to draw is that the

defendant was aware of the files on his computer and was in control of

them. K

M M
97. Mr Boyton submits that the court cannot rule out the

O 98. As noted earlier, around 2009 the defendant began to O
observe problems with the computer, variously described as breaking

started, the defendant replied that in 2006 he reinstalled the Windows

system which was 2-3 years before he began to observe problems with
C the computer. C
D 99. The problems included the computer automatically logging D
out after logging on; Real Player automatically popping up; the computer
E E
automatically connecting to the internet; and the speed of the computer
F getting slower and slower. F
G G
100. At the end of the first day the defendant gave evidence, I
H directed that the computer be set up the following morning. After cross- H
examination, Mr Boyton applied for leave to ask further questions about
I I
various pop-ups seen on the simulation of the computer’s user home
J screen/desktop when turning on the computer. J
K K
101. The defendant explained that when he experienced problems
L
with the computer he would see these pop-ups. Photographs were taken L
of the pop-ups and marked exhibits D6 & D7. When asked questions by
M M
the court a warning from Windows Security Centre popped up. This was
N photographed and marked “A”. N
O 102. Believing the computer had contracted a virus, the defendant O
purchased the antivirus software programme NOD 32 (exhibit D5) which
P P
he installed on the computer. Although in cross-examination the
Q defendant was unable to point to anything on the simulation of the Q
computer’s user home screen/desktop to show NOD 32 was installed,
R R
there is no doubt that NOD 32 was installed. In answer to the court, the
S defendant demonstrated by clicking on the start menu and going to S
programmes that NOD 32 was found by going to the programme Eset.
T T
Further during the demonstrations by the defendant, pop-ups were seen
U U
V V
33
A A
B B
which also clearly showed NOD 32 was installed. These pop-ups were
C not however photographed. C
D 103. After installation of NOD 32, warnings like exhibit D4 D
would automatically pop-up. When asked by Mr Boyton what he would
E E
do when a warning popped up, the defendant described three situations.
F First, the defendant would follow the direction of the warning and scan F
the computer to look for any virus or malicious programme. In cross-
G G
examination the defendant said that if any virus or malicious programme
H was found, these would be “quarantined”. When asked by the court what H
he understood by “quarantined”, the defendant replied just like going to
I I
hospital and then went on to say that when malicious software was found,
J J
he would opt to remove the file and not treat the file.
K K
104. Second, when browsing the internet, the user would be asked
L whether he wanted to continue or shut down the web page. Third, when L
using Foxy, the user would be informed that Foxy was trying to connect
M M
to the internet.
N N
105. The installation of NOD 32 did not however solve the
O O
computer problems which in fact became worse. Family members told
P the defendant that sometimes they “lost control” of the computer. When P
asked by the court whether there was anything that happened which
Q Q
resulted in the computer no longer being used, the defendant replied that
R when he last used the computer, he was unable to open the user home R
screen/desktop. The defendant said that if he remembered correctly he
S S
last used the computer in the winter prior to April 2013.

Discussion
C C
106. In cross-examination PC 4440 (PW2) agreed when he seized
D the computer that the computer was not turned on and was not connected D
to any cable or equipment. According to the data sheet prepared by DPC
E E
54
4384, the last time the computer was used was the 25 April 2013, which
F was about nine months prior to PC 4440 seizing the computer. F
G G
107. The fact the computer was not turned on and was not
H connected to any cable or equipment when seized from the defendant’s H
bedroom is consistent with the defendant’s evidence that he experienced
I I
problems with the computer, which led to him no longer using the
J computer. Nevertheless I have no hesitation in rejecting the defendant’s J
evidence that by April 2013 the computer was out of control and that
K K
when he last used the computer in the winter prior to April 2013, he could
L not access the user home screen/desktop. I do not find this evidence L
credible.
M M
N 108. Although in answer to the court DSPC 23344 said that he did N
not check whether the computer was working DSPC 23344 was able to
O O
demonstrate from the simulation of the computer that the computer was
P working. Further all the child pornography files, which had been created P
in 2008 and 2009, had last been viewed between 2008 and 2013. Two

109. The submission that the child pornography files may have
C been downloaded by a virus is, in my view, nothing more than C
speculation. In cross-examination after DSPC 23344 agreed that he did
D D
not investigate whether there was any virus on the computer, Mr Boyton
E asked DSPC 23344 whether he checked to see if there were any “pop-up E
windows” as a result of malicious software. DSPC 23344 replied that
F F
this will not happen. I reject the appearance of the pop-up windows was
G because of a virus. G
H 110. Contrary to the written submission of Mr Boyton, at no time H
was it ever put or suggested to DSPC 23344 that the child pornography
I I
found in the Foxy download folder was or may have been downloaded by
J
a virus.56 Apart from asking whether “pop-up windows” were as a result J
K
of malicious software, what Mr Boyton did was to show DSPC 23344 K
two information sheets prepared by the Information Technology Service
L L
Centre of The Chinese University of Hong Kong.
M M
111. DSPC 23344 was first referred to “Risks in Peer-to-Peer File
N Sharing” (exhibit D2). DSPC 23344 agreed the risks of file sharing set N
out in paragraph 2 A) and B) including that peer to peer software users
O O
can easily contract computer viruses and the software may also contain
P viruses and worms which prevent the computer from functioning properly. P
DSPC 23344 agreed that this would include slowing down of the
Q Q
computer and that freezing of the computer can occur. DSPC 23344
R again disagreed pop-up menus would appear because of a virus. R

B B
112. The second paper was “Know more about Foxy” (exhibit
C D3). DSPC 23344 was referred to part IV, paragraph 3, “Infection of C
virus or worm”. DSPC 23344 agreed with the statement that if the
D D
computer was affected by virus or worm, the Foxy settings could be
E changed without notice to the user. E
F 113. DSPC 23344 had not heard of the two viruses mentioned in F
this part. With regard to the two effects of the virus PE_POLIP A, DSPC
G G
23344 agreed that the virus may consume a large amount of system
H resources and cause the computer to become noticeably sluggish. DSPC H
23344 said that it may be the case the virus may install malicious
I I
software to disable the security system, modify system files and install
J J
additional malware.
K K
114. The agreement by DSPC 23344 to these statements amounts
L to no more than agreeing the effects of a virus or a worm on the operation L
of a computer. The defendant’s belief that there was a virus is no more
M M
than a belief. I find that there is no evidence before the court that there
N was or may have been a virus on the computer. N
O O
115. Even if there was a virus on the computer there must be
P evidence before the court that the downloading of the child pornography P
was or may have been because of a virus. There is no evidence before the
Q Q
court that the child pornography was or may have been downloaded by a
R virus. I reject the submission the child pornography may have been R
downloaded by a virus.
S S
116. If I am wrong and cannot rule out that the child pornography
T T
may have been downloaded by a virus, the question to be asked again is,
U U
V V
37
A A
B B
does this stop the inference being drawn that the defendant was in
C possession of the child pornography? In my view the answer is also no. C
Even if the child pornography was downloaded by a virus I am
D D
nevertheless satisfied for the reasons set out earlier, in particular that the
E files were easily accessible from Foxy and that the names of the child E
pornography files and the images of the four photo files can be seen when
F F
accessing the files from Foxy, a programme which the defendant admits
G he used, that the only inference to draw is that the defendant was aware of G
the files on his computer and was in control of them.
H H
117. Having carefully considered all the evidence I find I am
I I
satisfied so that I am sure that the prosecution have proved beyond
J J
reasonable doubt the defendant was in possession of the child
K
pornography, the defendant having control of and knowledge of the K
existence of the video files and photo files on the computer.
L L
Statutory defence
M M
N 118. The prosecution having proved beyond reasonable doubt that N
the defendant was in possession of the child pornography, it is open for
O O
the defendant to rely on any of the defences in section 4(3) of the
P Ordinance. By saying he was not aware of the existence of the child P
pornography on the computer the defendant relies on the statutory
Q Q
defence in section 4(3)(c) of the Ordinance that he had not seen the child
R pornography and did not know nor suspect it to be child pornography. R
S 119. A defendant is taken to establish any fact that needs to be S
established for the purpose of a defence under subsection (3)(c) if (a)
T T
sufficient evidence is adduced to raise an issue with respect to the fact;
U U
V V
38
A A
B B
and (b) the contrary is not proved by the prosecution beyond reasonable
C doubt. C
D 120. In HKSAR v. Ng Po On57 Ribeiro PJ explained the nature of D
an evidential burden. He stated:58
E E
F
“An evidential burden stands in contrast to a reverse F
persuasive burden. It does not require the accused to establish
anything as a matter of proof. An evidential burden arises
G where the defendant wishes to put in issue some matter that is G
potentially exculpatory while the prosecution continues to bear
the persuasive burden throughout. In such cases, there must be
H H
evidence supporting such exculpatory matter which is
sufficiently substantial that it raises a reasonable doubt as to the
I defendant’s guilt. Unless such reasonable doubt is removed, the I
prosecution fails to prove its case. If, on the other hand, the
accused fails to adduce or point to any evidence on the relevant
J issue or if the evidence adduced is rejected or is not sufficiently J
substantial to raise a reasonable doubt, the potentially
K exculpatory matter places no obstacle in the way of the K
prosecution proving its case beyond reasonable doubt. An
evidential burden, functioning in this manner, is wholly
L consistent with the presumption of innocence.” L
M 121. Later in the judgment Ribeiro PJ went on to add:59 M
N “It must be emphasised that an evidential burden is not N
something nominal or illusory. It requires the defendant to
adduce or otherwise be able to rely on evidence which is
O sufficiently substantial to raise a reasonable doubt which the O
prosecution must negative if he is to be convicted.”
P P
In R v Lambert, Lord Hope of Craighead put this point as
follows:
Q Q
“If the evidential burden were to be so slight as to make no
R difference – if it were to be enough, for example, for the accused R
merely to mention the defence without adducing any evidence –
important practical considerations would suggest that in the

39
A A
B general interest of the community the burden would have to be a B
persuasive one. But an evidential burden is not to be thought of
C as a burden which is illusory. What the accused must do is put C
evidence before the court which, if believed, could be taken by a
reasonable jury to support his defence.” 60
D D
122. This passage was also quoted in HKSAR v Hung Chan Wa.61
E E
Stock JA giving the judgment of the court said that the burden may be
F discharged regardless of the quarter from which the evidence derives but F
is not discharged by the mere mouthing of words by an accused.
G G
H
123. Having rejected the defendant’s evidence that he was not H
aware of the existence of the child pornography I find that the defendant
I I
has failed to adduce sufficient evidence to raise an issue with respect to
J the fact that he had not seen the child pornography and did not know nor J
suspect it to be child pornography. Even on the defendant’s evidence that
K K
he believed the child pornography may have been downloaded by a virus
L and that family members also used the computer, I find that the defendant L
has failed to adduce sufficiently substantial evidence that raises a
M M
reasonable doubt that he had not seen the child pornography and did not
N know nor suspect it to be child pornography. N
O 124. Although the prosecution are not required to prove the O
defendant had viewed the child pornography, I have nevertheless
P P
considered whether the defendant viewed the child pornography. I am
Q Q
satisfied so I am sure on the evidence, in particular that the child
R

C and the inherent improbability of other family members using the C

E pornography. E
F 125. In reaching my verdict I have carefully considered F
everything said by Mr Boyton both individually and collectively,
G G
including that none of the defendant’s personal files, photographs or
H documents were found in the same folder as the child pornography; 62 no H
files were deleted;63 and only a small quantity of pornography was found
I I
on the computer. Nothing said by Mr Boyton causes me to doubt the
J J
findings I have made. I am satisfied so I am sure there are no material
K
and significant discrepancies, improbabilities or omissions in the K
evidence, which cause me to doubt the findings I have made.

K K
Authority. There was no challenge to the expertise of Mr Lau who held a
L
higher diploma, a bachelor degree and a Master of Science in electrical L
engineering. Mr Lau had worked for the Authority since 1998 and had
M M
examined suspected radio apparatus for over seven years. I was satisfied
N Mr Lau was able to give expert evidence relating to the examination of N
apparatus for radiocommunications.
O O
130. Mr Lau testified that in layman terms the three radio-
P P
transceivers were walkie-talkies. All three were operable and worked
Q normally and were able to transmit and receive broadcast words. In Q
answer to the court Mr Lau said that the three radio-transceivers were
R R
apparatus for transmission by radio waves.

131. In cross-examination Mr Lau disagreed that when he
C received all three radio-transceivers they did not have batteries. Mr Lau C
said exhibit P4 had a battery and pointed out to the court the battery
D D
which was attached to the bottom of the radio-transceiver. Mr Lau
E confirmed that he was asked to examine a total of four radio-transceivers E
one of which he did not classify as communications apparatus because
F F
the radio-transceiver was not working. Mr Lau disagreed P2, P3 and P4
G were also not functioning. G
H Defence evidence H
I I
132. In summary the defendant testified that the three radio-
J transceivers were purchased for photo taking during war games. Two J
were purchased from Yahoo (exhibits P2 & P3) and one from Apliu
K K
Street in Sham Shui Po (exhibit P4). The defendant had never used the
L three radio-transceivers and had no idea if they were functional or not. L
M M
133. Two of the three radio-transceivers (exhibits P2 & P3) had
N been seized by the police in 2011 and later returned to the defendant as N
evidenced by the “Receipt of Property Return” (exhibit D1). The police
O O
told the defendant that they had been examined by an expert and that
P there was no problem with them. The defendant accordingly felt that P
there was no problem with him possessing the radio-transceivers and that
Q Q
he would not be prosecuted for possessing them.

he had never used the three radio-transceivers and had no idea if they

were functional or not. I do not find this evidence credible. In cross-
C examination when put he knew they were in fact radio transmitters the C
defendant agreed and added, for the first time, that he knew they were not
D D
functional when he bought them.
E E
135. When the court clarified with the defendant his evidence as
F to whether he knew the radio-transceivers were functional, the defendant F
replied that when he bought the radio-transceivers he really did not know
G G
whether they were functional or not. When asked why he said in cross-
H examination he knew they were not functional the defendant replied he H
was told by the seller that they were not functional.
I I
J 136. I accept the expert evidence of Mr Lau. Mr Lau examined J
four radio-transceivers one of which he found was not working. I am
K K
satisfied that if any of the three radio-transceivers were not working Mr
L Lau would also have said they were not working. L
M M
137. I am satisfied so I am sure that the three radio-transceivers
N fall within the definition in the Ordinance of radiocommunications N
transmitting apparatus for which a licence is required.

Strict liability
P P
Q 138. At the commencement of the trial Mr Tracy said the offence Q
was not one of strict liability. However, in closing submission Mr Tracy,
R R
relying on the decision in HKSAR v Uniglobe Telecom (Far East)
S Ltd,66submits the offence is one of strict liability. 67 Mr Boyton’s position S

B B
from the beginning has been that the offence, being a licensing matter, is
C one of strict liability. C
D 139. The Court of Appeal in Uniglobe held that the offences of D
maintaining a means of telecommunication without a licence and using
E E
radio communication apparatus without a licence were offences of strict
F liability. On appeal to the Court of Final Appeal the court in dismissing F
an appeal against conviction for maintaining a means of
G G
telecommunication without a licence confirmed that the offence was one
H of strict liability.68 In allowing the appeal against conviction for using H
radio communication apparatus without a licence the Court of Final
I I
Appeal did not consider whether the offence was also one of strict
J J
liability.
K K
140. Using radio communication apparatus without a licence is an
L offence contrary to section 8(1)(b) of the Telecommunications Ordinance, L
the same subsection under which the defendant is charged with
M M
possessing radiocommunication apparatus without a licence.
N N
141. The Court of Appeal did not consider whether the offence of
O O
possession was also one of strict liability. Whether an offence is one of
P strict liability is to be determined in accordance with the principles P
established in Hin Lin Yee & another v HKSAR,69 and Kulemesin Yuriy &
Q Q
another v HKSAR.70 As both parties agree the offence is one of strict
R liability I have not been addressed on this issue and therefore which of R
the five alternatives apply to possession.

B B
142. In the circumstances I proceed on the same basis as the Court
C of Final Appeal in Uniglobe, that the offence is one of strict liability in C
that the prosecution do not have to prove guilty knowledge, but that it is a
D D
defence for the accused to prove, on a balance of probabilities, that he
E honestly held upon reasonable grounds, a belief in the existence of facts E
which, if true, would make his conduct innocent.71
F F
143. I have grave reservations that the police, when returning the
G G
two radio-transceivers, would have told the defendant that they had been
H examined by an expert and that there was no problem with them. From H
the “Receipt of Property Return” the officers returning the property were
I I
from the Property Office and not officers involved in the investigation
J J
arising from the seizure of the radio-transceivers.
K K
144. The fact remains, however, that the prosecution have not
L sought to adduce any evidence in rebuttal as to what the defendant was L
told; why the radio-transceivers were seized in the first place and the
M M
reason for their return. Whatever the defendant was told I am satisfied,
N on the evidence, that by returning the radio-transceivers the defendant N
honestly held upon reasonable grounds that he would not be prosecuted.
O O
This belief in my view also extends to the possession of the third radio-
P transceiver. P
Q Q
145. The defendant is acquitted of charge 2.
