1. Actus Reus & Omissions | 犯罪行为与不作为
The actus reus is the external element of a crime – a voluntary act (or qualifying omission) that causes harm. The conduct must be willed; an involuntary act, such as a reflex or spasm, does not satisfy actus reus (Hill v Baxter).
犯罪行为是犯罪的外部要件——造成伤害的自愿行为（或符合条件的不作为）。行为必须是意志支配的；诸如反射或痉挛等非自愿行为不满足犯罪行为要件（Hill v Baxter 案）。
An omission will only incur liability where the defendant is under a legal duty to act. Such a duty can arise from statute (e.g. Road Traffic Act), a contract (R v Pittwood), a special relationship (R v Gibbins and Proctor – parents who starved child), voluntary assumption of responsibility (R v Stone and Dobinson), or creation of a dangerous situation (R v Miller – failing to put out a fire one started).
只有在被告负有法律行为义务时，不作为才会产生责任。这种义务可源于制定法（如《道路交通法》）、合同（R v Pittwood 案）、特殊关系（R v Gibbins and Proctor 案——父母饿死孩子）、自愿承担责任（R v Stone and Dobinson 案）或制造了危险局面（R v Miller 案——未扑灭自己引发的火）。
2. Mens Rea: Intention & Recklessness | 犯意：故意与轻率
Mens rea is the mental element. Direct intent exists where the consequence is the defendant’s aim or purpose (R v Mohan). Oblique intent applies where the result is a virtual certainty and the defendant appreciates this (R v Woollin). The jury is entitled to find intention only where death or serious harm was a virtual certainty and the defendant foresaw it as such.
犯意是主观心理要件。直接故意指结果系被告之目的或意图（R v Mohan 案）。间接故意适用于结果几乎是必然发生且被告认识到这一点的情形（R v Woollin 案）。仅当死亡或严重伤害几乎是必然的并且被告如此预见时，陪审团才有权认定存在故意。
Recklessness in criminal law means the defendant foresees an unjustified risk and goes on to take it (R v Cunningham – subjective test). This contrasts with objective recklessness, which was abolished for most offences by R v G and another. For criminal damage, the test is now fully subjective.
刑法中的轻率指被告预见到不正当的风险却仍然采取该行为（R v Cunningham 案——主观标准）。这与客观轻率不同，后者已通过 R v G and another 案在多数犯罪中被废除。对于刑事损坏罪，现在完全采用主观标准。
3. Causation in Criminal Law | 刑法中的因果关系
To establish liability, the prosecution must show both factual and legal causation. Factual causation is determined by the ‘but for’ test: but for the defendant’s conduct, would the result have occurred? (R v White). Legal causation requires that the defendant’s act be the substantial and operating cause of the result (R v Smith).
要确立责任，控方须证明事实因果关系与法律因果关系。事实因果采用“若无则不”标准：若无被告的行为，结果是否会发生？（R v White 案）。法律因果要求被告的行为是结果的实质性且有效的致因（R v Smith 案）。
An intervening act (novus actus interveniens) may break the chain of causation. Acts of a third party will only break it if they are free, deliberate and informed (R v Pagett). Medical negligence will rarely break the chain unless it is so potent as to render the original wound merely a setting (R v Cheshire). The thin skull rule instructs that the defendant must take the victim as found (R v Blaue).
介入行为（novus actus interveniens）可能中断因果关系链。第三方的行为仅在自由、蓄意且知情的情况下才中断因果链（R v Pagett 案）。医疗过失极少中断因果链，除非它如此有力，以致初始伤害仅为背景（R v Cheshire 案）。“薄头骨规则”要求被告必须接受受害人的原有状况（R v Blaue 案）。
4. Strict Liability | 严格责任
Strict liability offences require no mens rea for at least one element of the actus reus. Liability is imposed simply on proof of the prohibited conduct. These are usually regulatory or quasi-criminal offences (e.g. food safety, pollution) where Parliament intended to dispense with a mental requirement (Gammon Ltd v Attorney-General of Hong Kong).
严格责任犯罪不要求对犯罪行为的至少一项要素存在犯意。只需证明被禁止的行为即可施加责任。这类犯罪通常是监管性或准刑事犯罪（如食品安全、污染），且议会意图免除主观要件（Gammon Ltd v Attorney-General of Hong Kong 案）。
To determine if an offence is strict liability, courts presume mens rea is required unless statute clearly excludes it; consider the gravity of punishment and the social danger addressed (Sweet v Parsley). Common examples include selling alcohol to a minor and driving without insurance.
在判断某犯罪是否为严格责任时，法院推定要求犯意，除非制定法明确排除；并考虑惩罚严厉性及所针对的社会危害（Sweet v Parsley 案）。常见例子包括向未成年人售酒、无保险驾驶。
5. Murder & Partial Defences | 谋杀与部分抗辩
Murder is the unlawful killing of a human being with malice aforethought, express or implied (R v Moloney). Malice aforethought means an intention to kill or cause grievous bodily harm. Partial defences reduce murder to voluntary manslaughter: diminished responsibility and loss of control.
谋杀是带有明示或默示恶意的非法杀人（R v Moloney 案）。恶意预谋指意图杀人或造成严重身体伤害。部分抗辩可将谋杀降为自愿非预谋杀人：减轻责任和丧失控制。
Diminished responsibility (s.2 Homicide Act 1957, amended by s.52 Coroners and Justice Act 2009) requires an abnormality of mental functioning arising from a recognised medical condition, which substantially impaired the defendant’s ability to understand the nature of the conduct, form a rational judgment, or exercise self‑control (R v Byrne).
减轻责任（《1957年凶杀法》第2条，经《2009年死因裁判与司法法》第52条修订）要求存在因公认医学状况引发的精神功能异常，并严重削弱被告理解行为性质、形成理性判断或自我控制的能力（R v Byrne 案）。
Loss of control (s.54‑55 Coroners and Justice Act 2009) applies where the defendant killed as a result of a loss of self‑control caused by a qualifying trigger (fear of serious violence or things said/done constituting circumstances of an extremely grave character) and a person of the same age and sex with a normal degree of tolerance would have reacted similarly (R v Clinton).
丧失控制（《2009年死因裁判与司法法》第54‑55条）适用于被告因符合资格的触发因素（对严重暴力的恐惧，或所言之事物构成极为严重的状况）引发丧失自我控制而杀人，且同龄同性别具备正常容忍度的人会有类似反应（R v Clinton 案）。
6. Non-Fatal Offences Against the Person | 非致命侵犯人身罪
Assault and battery are distinct common law offences. Assault is causing the victim to apprehend immediate unlawful force (R v Ireland). Battery is the actual application of unlawful force, however slight (Collins v Wilcock). Both require intention or recklessness (R v Venna).
暴行与殴打是不同的普通法犯罪。暴行是使受害人担忧即将遭受非法暴力（R v Ireland 案）。殴打是实际施加非法暴力，无论多么轻微（Collins v Wilcock 案）。二者均要求故意或轻率（R v Venna 案）。
Offences under the Offences Against the Person Act 1861: s.47 assault occasioning actual bodily harm (ABH) – any hurt or injury calculated to interfere with health or comfort (R v Miller). S.20 malicious wounding or inflicting grievous bodily harm (GBH) – must be a serious harm, with foresight of some harm (R v Savage; R v Parmenter). S.18 wounding or causing GBH with intent – specific intent to cause GBH or resist arrest (R v Belfon).
《1861年侵犯人身罪法》下的犯罪：第47条暴行致实际身体伤害（ABH）——任何旨在干扰健康或舒适的伤害（R v Miller 案）。第20条恶意伤人致严重身体伤害（GBH）——须为严重伤害，且预见到某些伤害（R v Savage; R v Parmenter 案）。第18条蓄意伤人致严重身体伤害——具体意图造成严重身体伤害或抗拒逮捕（R v Belfon 案）。
7. Negligence: Duty of Care | 过失侵权：注意义务
Negligence requires a duty of care, breach of that duty, and resultant damage. The modern approach to duty stems from Caparo Industries plc v Dickman: foreseeability of harm, proximity between the parties, and whether it is fair, just and reasonable to impose a duty. An incremental approach is favoured (Robinson v Chief Constable of West Yorkshire Police).
过失侵权要求存在注意义务、违反该义务及由此造成的损害。注意义务的现代判断源自 Caparo Industries plc v Dickman 案：损害的可预见性、当事人之间的近邻性，以及施加义务是否公平、公正与合理。倾向于采用渐进方式（Robinson v Chief Constable of West Yorkshire Police 案）。
Established categories include road users (Nettleship v Weston), doctor–patient (Bolam v Friern Hospital Management Committee), employer–employee (Wilsons & Clyde Coal Co v English), and manufacturer–consumer (Donoghue v Stevenson – the ‘neighbour principle’). Courts also impose duties on public bodies subject to policy considerations.
已确立的类别包括道路使用者（Nettleship v Weston）、医患关系（Bolam v Friern Hospital Management Committee）、雇主与雇员（Wilsons & Clyde Coal Co v English）及制造商与消费者（Donoghue v Stevenson——“邻人原则”）。法院也基于政策考量对公共机构施加义务。
8. Negligence: Breach of Duty & Damage | 过失侵权：违反义务与损害
Breach is assessed by the standard of the reasonable person in the defendant’s position (Blyth v Birmingham Waterworks). The reasonable person is not a perfect person: the standard is objective. Professionals must act in accordance with a responsible body of professional opinion (Bolam test, refined by Bolitho v City and Hackney HA, requiring that the opinion be logical).
违反义务以处于被告位置的理性人标准来评判（Blyth v Birmingham Waterworks 案）。理性人并非完美之人：标准是客观的。专业人员的行为须符合负责的专业意见体（Bolam 标准，经 Bolitho v City and Hackney HA 案完善，要求该意见须具逻辑性）。
The damage must be caused by the breach and not be too remote. Causation in tort applies the ‘but for’ test (Barnett v Chelsea and Kensington Hospital Management Committee). Remoteness is governed by The Wagon Mound No 1: the kind of damage must have been reasonably foreseeable. The thin skull rule also applies (Smith v Leech Brain).
损害须由违反义务造成且不能过于遥远。侵权因果关系采用“若无则不”标准（Barnett v Chelsea and Kensington Hospital Management Committee 案）。遥远性由 The Wagon Mound No 1 案规范：损害种类必须是可以合理预见的。薄头骨规则同样适用（Smith v Leech Brain 案）。
9. Occupiers’ Liability | 占用人责任
Occupiers of premises owe a common duty of care to lawful visitors (Occupiers’ Liability Act 1957). The duty is to take such care as is reasonably necessary to ensure the visitor will be reasonably safe (s.2(2)). Children are owed a higher standard (s.2(3)(a); Glasgow Corp v Taylor), and tradesmen are expected to guard against risks peculiar to their trade (s.2(3)(b); Roles v Nathan).
场所占用人对合法访客负普通注意义务（《1957年占用人责任法》）。该义务要求采取合理必要的注意，确保访客合理安全（第2(2)条）。对儿童负有更高标准（第2(3)(a)条；Glasgow Corp v Taylor 案），而工匠应防范自己行业的特殊风险（第2(3)(b)条；Roles v Nathan 案）。
The Occupiers’ Liability Act 1984 imposes a limited duty towards trespassers. The occupier owes a duty if aware of the danger and has reasonable grounds to believe a trespasser may come into the vicinity, and the risk is one against which he may reasonably be expected to offer some protection (s.1(3); Ratcliff v McConnell). The duty is to take reasonable care to see that the trespasser does not suffer injury (s.1(4)).
《1984年占用人责任法》对非法侵入者施加有限义务。占有人在意识到危险并有合理理由相信侵入者可能进入附近、且该风险属于可合理期待其提供一些保护的情形下负有义务（第1(3)条；Ratcliff v McConnell 案）。该义务为采取合理注意避免侵入者受伤害（第1(4)条）。
10. General Defences: Consent & Self-Defence | 一般抗辩：同意与自卫
Consent can be a defence to non‑fatal offences. The victim’s consent must be true, informed, and freely given (R v Olugboja). Consent is no defence to bodily harm unless the activity falls within a recognised category (e.g. sports, surgery, rough horseplay) as set out in R v Brown and R v Wilson. Public policy limits the scope of consent.
同意可作为非致命犯罪的抗辩。受害人的同意须真实、知情且自愿（R v Olugboja 案）。除非活动属于公认类别（如体育运动、手术、粗野玩闹），同意不能作为身体伤害的抗辩，此原则由 R v Brown 和 R v Wilson 案确立。公共政策限制了同意的适用范围。
Self‑defence, defence of another and prevention of crime are governed by common law and s.76 Criminal Justice and Immigration Act 2008. The force used must be reasonable in the circumstances as the defendant genuinely believed them to be (R v Gladstone Williams). Whether force is proportionate is assessed objectively, allowing for the fact that a person acting in the heat of the moment cannot weigh to a nicety the exact measure of necessary action (s.76(7); R v Palmer).
自卫、防卫他人及预防犯罪由普通法和《2008年刑事司法与移民法》第76条规范。所使用的武力须在被告真诚相信的情境下是合理的（R v Gladstone Williams 案）。武力是否相称须客观评估，但允许考虑到在激愤之下行动的人无法精确衡量必要行动的精确尺度（第76(7)条；R v Palmer 案）。
