漏水責任與違章建築？申索駁回

### 案件基本資料 - 案件名稱：LOKE YUEN JEAN TAK ALICE v WONG KIT YING and PHILIPPE NEVEU - 法院：高等法院原訟法庭 (Court of First Instance, CFI) - 法官：Hon Marlene Ng J - 判決日期：2019年8月1日 ### 案情摘要 原告是Flat GE的業主，聲稱自2006年11月至2012年3月期間，Flat GE因樓上Flat 1E的漏水而遭受損失和損害。Flat 1E的業主是第一被告，第二被告及其家人則為Flat 1E的租客。原告指控漏水構成滋擾，且被告知情或應知情但未有制止，或因被告疏忽所致。被告否認責任，並聲稱漏水是因原告的違章建築（UBWs）及Flat GE的排水系統改動所致，且原告未能妥善維護物業。第一被告亦向第二被告及第三方提出彌償申索，指控他們違反租約或疏忽。 ### 核心法律爭議 本案的核心法律爭議在於：(1) Flat GE的漏水是否源自Flat 1E，以及被告是否對此負有法律責任（包括滋擾或疏忽）；(2) 若被告有責任，漏水是否由原告的違章建築或其排水系統改動所致，從而構成共同過失或中斷因果關係；(3) 若被告有責任，第一被告與第二被告之間應如何分攤責任；(4) 原告所申索的損害賠償金額是否合理且有充分證據支持。 ### 判決理由 法庭裁定，漏水問題的根本原因在於Flat GE的違章建築（Yard / Light Well Structures）的防水功能失效。即使Flat 1E的排水管有缺陷，若Flat GE的屋頂防水功能良好，漏水也不會進入Flat GE內部。法庭認為，原告未能排除雨水及其他非源自Flat 1E的水源作為漏水原因，且Flat GE屋頂的缺陷是導致損害的真正有效原因，構成中斷因果關係（novus actus interveniens）。因此，即使Flat 1E的排水管有缺陷，被告亦不應承擔責任。此外，法庭認為第二被告已採取合理行動處理投訴，並無疏忽。 ### 引用案例與條文 本案引用了多個關於滋擾（nuisance）和疏忽（negligence）的法律原則，包括： - Sedleigh-Denfield v O'Callagan & ors [1940] AC 880：確立了佔用人對持續滋擾的責任，即在知情或應知情的情況下未能採取合理措施終止滋擾。 - Leakey & ors v National Trust for Places of Historic Interest or Natural Beauty [1980] 1 QB 485：進一步闡釋了佔用人對持續滋擾的責任範圍，包括對潛在缺陷的責任。 - 張秀玲及吳炳漢對鄭禮莊 CACV268/98：本地權威案例，解釋了滋擾中「知情」的兩種情況：實際知情或在合理謹慎下應知情。 - The Wagon Mound (No 2) [1967] 1 AC 617：確立了滋擾責任需要可預見性。 - Goldman v Hargrave & ors [1967] 1 AC 645：闡明了佔用人減輕滋擾的「衡量責任」（measured duty），需考慮所有情況。 - Spencer v Wincanton Holdings Ltd [2010] PIQR P8：討論了中斷因果關係（novus actus interveniens）的「公平性」原則。 - Carslogie SS Co Ltd v Royal Norwegian Government [1952] AC 292：關於非侵權事件對因果關係的影響。 - Lo Yuk Sui v Fubon Bank (Hong Kong) Limited formerly known as International Bank of Asia Limited CACV47/2017：關於合約條款默示的測試。 ### 裁決與命令 原告對第一被告和第二被告的申索被駁回。第一被告對第二被告的彌償申索以及第二被告對第一被告的彌償申索均被駁回。第一被告對第三方（TP1和TP2）的申索亦被駁回。原告須支付第一被告和第二被告在主訴訟中的訟費。第一被告須支付第二被告在彌償訴訟中的訟費，但原告須彌償第一被告該筆訟費。第一被告須支付第三方在第三方訴訟中的訟費。 ### 判決啟示 本案強調了在漏水糾紛中，原告必須證明被告的行為是導致損害的有效原因，而非僅僅是「若非如此則不會發生」（but for）的原因。法庭明確指出，若受影響物業自身的結構缺陷（例如防水失效的屋頂）是導致漏水進入內部的真正原因，則即使樓上物業有缺陷，樓上業主也可能不負責任，因為這構成中斷因果關係。此外，法庭對專家證人的專業操守和證據可靠性提出了嚴格要求，特別是在證據收集和測試程序方面。 --- ### 免責聲明 本摘要由人工智能自動生成，內容可能存在錯誤或遺漏，僅供參考，不構成法律意見。如需法律建議，請諮詢合資格律師。### Case Details - Case Name: LOKE YUEN JEAN TAK ALICE v WONG KIT YING and PHILIPPE NEVEU - Court: Court of First Instance (CFI) - Judge: Hon Marlene Ng J - Date of Judgment: 1 August 2019 ### Factual Background The Plaintiff, owner of Flat GE, claimed for loss and damages due to water leakages from Flat 1E (located directly above Flat GE) between November 2006 and March 2012. The 1st Defendant owned Flat 1E, and the 2nd Defendant and his family were tenants. The Plaintiff alleged the leakages constituted a nuisance that the Defendants knew or ought to have known about but permitted to continue, and/or were caused by the Defendants' negligence. The Defendants denied liability, asserting the leakages were caused or contributed to by the Plaintiff's unauthorized building works (UBWs) and alterations to Flat GE's drainage system, and her failure to maintain the property. The 1st Defendant also sought indemnity from the 2nd Defendant and 2nd Third Party for breach of tenancy or negligence. ### Key Legal Issues The core legal issues in dispute were: (1) whether the water leakages in Flat GE originated from Flat 1E, and if the Defendants were legally liable for nuisance or negligence; (2) if liable, whether the leakages were caused by the Plaintiff's UBWs or drainage alterations, constituting contributory negligence or a novus actus interveniens; (3) if liable, how liability should be apportioned between the 1st and 2nd Defendants; and (4) whether the Plaintiff's claimed damages were reasonable and sufficiently proven. ### Ratio Decidendi The Court found that the fundamental cause of the water leakages was the defective waterproofing of Flat GE's unauthorized building works (Yard / Light Well Structures). Even if Flat 1E's drainage pipes were defective, water would not have entered Flat GE if its roof waterproofing was sound. The Court held that the Plaintiff failed to exclude rainwater and other non-Flat 1E sources as causes of leakage, and that the defects in Flat GE's rooftops constituted the real and effective cause of the damage, acting as a novus actus interveniens. Therefore, the Defendants were not liable, even if Flat 1E's pipes were defective. Furthermore, the 2nd Defendant was found to have acted reasonably in addressing complaints and was not negligent. ### Key Precedents & Statutes This case cited several legal principles concerning nuisance and negligence, including: - Sedleigh-Denfield v O'Callagan & ors [1940] AC 880: Established the liability of an occupier for continuing a nuisance if, with knowledge or presumed knowledge, they fail to take reasonable steps to abate it. - Leakey & ors v National Trust for Places of Historic Interest or Natural Beauty [1980] 1 QB 485: Further elaborated on the scope of an occupier's duty regarding continuing nuisances, including latent defects. - 張秀玲及吳炳漢對鄭禮莊 CACV268/98: A local authority clarifying 'knowledge' in nuisance as either actual or presumed under reasonable diligence. - The Wagon Mound (No 2) [1967] 1 AC 617: Affirmed foreseeability as a requirement for liability in nuisance. - Goldman v Hargrave & ors [1967] 1 AC 645: Defined the 'measured duty' of an occupier to abate a nuisance, considering all circumstances. - Spencer v Wincanton Holdings Ltd [2010] PIQR P8: Discussed the 'fairness' principle in determining a novus actus interveniens. - Carslogie SS Co Ltd v Royal Norwegian Government [1952] AC 292: On the impact of non-tortious events on causation. - Lo Yuk Sui v Fubon Bank (Hong Kong) Limited formerly known as International Bank of Asia Limited CACV47/2017: On the test for implied contractual terms. ### Decision & Orders The Plaintiff's claims against the 1st Defendant and 2nd Defendant were dismissed. The 1st Defendant's contribution claim against the 2nd Defendant and the 2nd Defendant's contribution claim against the 1st Defendant were both dismissed. The 1st Defendant's third-party claim against TP1 and TP2 was also dismissed. The Plaintiff was ordered to pay the 1st and 2nd Defendants' costs for the Main Proceedings. The 1st Defendant was ordered to pay the 2nd Defendant's costs for the contribution proceedings, with the Plaintiff indemnifying the 1st Defendant for these costs. The 1st Defendant was ordered to pay the Third Parties' costs for the Third Party Proceedings. ### Key Takeaways This case highlights that in water leakage disputes, a plaintiff must prove the defendant's actions were the effective cause of damage, not merely a 'but for' cause. The court clarified that if structural defects in the affected property (e.g., failed roof waterproofing) are the true cause of water ingress, the upstairs owner may not be liable, as this constitutes a novus actus interveniens. Furthermore, the judgment underscores strict requirements for expert witness professionalism and evidence reliability, particularly regarding evidence collection and testing procedures. --- ### Disclaimer This summary is AI-generated and may contain errors or omissions.
