1. Criminal Liability Formula | 刑事责任基本公式
At the heart of almost every crime stands the same building‑block equation. The prosecution must prove beyond reasonable doubt that the defendant completed the actus reus and possessed the requisite mens rea at the same moment, and that no defence applies.
几乎所有犯罪的核心都是同一个构成公式。控方必须排除合理怀疑地证明被告在行为时同时具备犯罪行为和犯罪意图，且不存在任何抗辩事由。
Actus Reus + Mens Rea − Valid Defence = Guilt
犯罪行为 + 犯罪意图 − 有效抗辩 = 有罪
The actus reus can be a positive act, an omission (where a legal duty exists, such as a contract, a special relationship, or the assumption of care), or a state of affairs. Mens rea ranges from intention and recklessness to dishonesty and negligence, depending on the specific offence.
犯罪行为可以是积极行为、不作为（当存在法律义务如合同、特殊关系或自愿承担照顾责任时）或特定状态。犯罪意图从意图、轻率到不诚实、过失不等，视具体罪名而定。
Coincidence of actus reus and mens rea is essential; the courts may stretch a continuing act (Fagan v MPC) or treat a series of acts as a single transaction (Thabo Meli v R) to secure a conviction.
犯罪行为与犯罪意图必须同时发生；法院可能通过认定持续性行为（Fagan 案）或将一系列行为视为单一交易（Thabo Meli 案）来确保定罪。
2. Murder: Actus Reus & Mens Rea | 谋杀罪的客观与主观要件
Murder is a common‑law offence carrying a mandatory life sentence. Its classical definition comes from Lord Coke: the unlawful killing of a reasonable creature in being under the Queen’s peace with malice aforethought.
谋杀是普通法上的犯罪，须判处终身监禁。其经典定义源自柯克大法官：在王国内非法杀死一个具有理性的生命体，且具有预谋恶意。
Unlawful Killing + Human Being + Queen’s Peace + Malice Aforethought = Murder
非法杀人 + 人类 + 王国和平 + 预谋恶意 = 谋杀
Malice aforethought means an intention to kill or an intention to cause grievous bodily harm (Vickers; Cunningham). It does not require pre‑planning. A victim is a ‘reasonable creature in being’ once they are fully expelled from the mother’s body and have an independent circulation (AG’s Ref (No 3 of 1994)).
预谋恶意指意图杀人或意图造成严重身体伤害（Vickers 案；Cunningham 案），无需事先计划。“具有理性的生命体”指胎儿完全脱离母体并获得独立血液循环之后（1994年第3号检察总长参考案）。
Factual causation ‘but for’ (White) and legal causation (substantial and operative cause, Smith) must be established. An intervening act (novus actus interveniens) will break the chain only if it is free, deliberate and informed.
必须确立事实因果关系“若非”标准（White 案）和法律因果关系（实质且起作用的致因，Smith 案）。仅当介入行为是自由、有意且知情的，才会中断因果链条。
3. Voluntary Manslaughter: Partial Defences | 非自愿误杀：部分抗辩
Where the elements of murder are present but a partial defence succeeds, the charge is reduced to voluntary manslaughter. The two main partial defences under the Coroners and Justice Act 2009 are loss of control and diminished responsibility.
当谋杀要件成立但部分抗辩成功时，指控降为自愿误杀。依据《2009年死因裁判官与司法法》，两项主要的部分抗辩是失控和减轻责任。
AR + MR − (Loss of Control or Diminished Responsibility) = Voluntary Manslaughter
犯罪行为 + 犯罪意图 − (失控或减轻责任) = 自愿误杀
For loss of control (s.54–55): D must have lost self‑control because of a qualifying trigger (fear of serious violence, or things said/done that constituted circumstances of an extremely grave character and caused D to have a justifiable sense of being seriously wronged). A person of D’s age and sex, with a normal degree of tolerance and self‑restraint, might have reacted similarly. Sexual infidelity alone is not a trigger.
失控抗辩（第54-55条）：被告必须因法定触发事件失去自我控制——恐惧严重暴力，或者有关言行性质极其严重且导致被告产生合理的被严重冤枉感。一个与被告同年龄、同性别的、具有正常容忍度和自我克制力的人在同样情况下可能做出类似反应。单纯的性不忠不构成触发事件。
Diminished responsibility (s.2 Homicide Act 1957 as amended): D must suffer from an abnormality of mental functioning arising from a recognised medical condition, which substantially impaired his ability to understand the nature of his conduct, form a rational judgment, or exercise self‑control, and provides an explanation for the killing.
减轻责任（《1957年杀人罪法》第2条修订版）：被告须因公认的医学状况导致精神功能异常，该异常实质上削弱其理解行为性质、形成理性判断或行使自我控制的能力，并且为杀人行为提供了解释。
4. Involuntary Manslaughter: Unlawful Act & Gross Negligence | 非自愿误杀：非法行为与重大过失
Involuntary manslaughter captures killings where the defendant lacked the mens rea for murder but still caused death with sufficient fault. The two routes are unlawful act manslaughter (constructive manslaughter) and gross negligence manslaughter.
非自愿误杀涵盖被告缺乏谋杀意图但仍因充分过错导致死亡的情形。两条路径为非法行为误杀（推定误杀）和重大过失误杀。
Unlawful act + Dangerous + Causes death = UAM
非法行为 + 危险性 + 造成死亡 = 非法行为误杀
The unlawful act must be a crime (Lamb), objectively dangerous in the sense that a sober and reasonable person would recognise the risk of some harm (Church), and must cause death (Goodfellow). It need not be directed at the victim.
非法行为必须是犯罪（Lamb 案），在清醒的合理人看来具有导致某种伤害的危险性（Church 案），并且实际导致死亡（Goodfellow 案）。该行为无需针对被害人。
Duty of care + Breach + Gross negligence + Causes death = GNM
注意义务 + 违反 + 重大过失 + 造成死亡 = 重大过失误杀
Gross negligence manslaughter (Adomako) requires an existing duty of care, a breach of that duty which caused death, and a finding that the breach was so gross as to amount to a crime – a jury question of whether the conduct was truly exceptionally bad.
重大过失误杀（Adomako 案）要求存在注意义务、违反义务并造成死亡，且该违反行为极其严重，足以构成犯罪——这是一个由陪审团判断的行为是否确实异常恶劣的问题。
5. Non‑Fatal Offences Against the Person | 非致命人身侵害犯罪
The Offences Against the Person Act 1861 (OAPA 1861) creates a hierarchy of assault‑based crimes. Memorising their definitions as simple equations helps organise answer plans.
《1861年人身侵害罪法》建立了以袭击为基础的犯罪层级。将其定义记忆为简单的等式有助于组织答题思路。
Apprehension of immediate unlawful force + Intention/recklessness = Assault
对即时非法暴力的恐惧 + 意图/轻率 = 普通威胁
Application of unlawful force + Intention/recklessness = Battery
实施非法暴力 + 意图/轻率 = 普通殴打
Assault and battery are statutory offences under s.39 Criminal Justice Act 1988, punishable by up to six months’ imprisonment. Any touching without consent suffices for battery (Collins v Wilcock).
威胁与殴打属于《1988年刑事司法法》第39条规定的法定罪行，最高可判处六个月监禁。任何未经同意的触碰即构成殴打（Collins v Wilcock 案）。
Assault/battery + Occasioning actual bodily harm + Intention/recklessness (as to assault/battery) = s.47 ABH
威胁/殴打 + 造成实际身体伤害 + 对威胁/殴打的意图/轻率 = 第47条实际身体伤害
ABH includes any hurt or injury calculated to interfere with health or comfort (Miller); psychiatric harm can suffice if a recognised clinical condition. For s.20 malicious wounding or inflicting GBH, the defendant must intend some harm or be reckless as to some harm, and the result is wounding (break of both dermis) or really serious harm.
实际身体伤害包括任何旨在干扰健康或舒适的疼痛或损伤（Miller 案）；可识别的精神疾病也可构成。对于第20条恶意伤人或造成严重身体伤害，被告须意图造成某些伤害或轻率地造成某些伤害，而结果是割伤（真皮断裂）或真正严重的伤害。
Wounding/causing GBH + Intention to cause GBH or resist arrest = s.18 GBH with intent
伤害/造成严重身体伤害 + 意图造成严重身体伤害或拒捕 = 第18条蓄意严重身体伤害
6. Property Offences: Theft, Robbery, Burglary | 财产犯罪：盗窃、抢劫、入室盗窃
The Theft Act 1968 defines theft and its aggravated cousins. The five‑part definition of theft acts as the foundation of all property dishonesty offences.
《1968年盗窃罪法》定义了盗窃及其加重犯罪。盗窃的五要件定义是所有财产不诚实犯罪的基础。
Appropriation + Property + Belonging to another + Dishonesty + Intention to permanently deprive = Theft
据为己有 + 财产 + 属于他人 + 不诚实 + 永久剥夺意图 = 盗窃
Appropriation (s.3) is any assumption of the rights of an owner; even a later assumption after honest acquisition can be theft (Hinks). Dishonesty is now assessed by the Ivey test: what was the defendant’s actual knowledge/belief as to the facts, and was the conduct dishonest by the objective standards of ordinary decent people? The Ghosh direction is no longer good law.
据为己有（第3条）指任何行使所有者权利的行为；即使在诚实取得后再次行使权利也可构成盗窃（Hinks 案）。不诚实现采用 Ivey 标准：考察被告对事实的实际认知或信念，并以普通正派人客观标准判断该行为是否不诚实。Ghosh 标准已不再适用。
Theft + Force or threat of force immediately before or at the time of stealing = Robbery (s.8)
盗窃 + 在盗窃之前或当时使用暴力或暴力威胁 = 抢劫（第8条）
Burglary under s.9(1)(a) requires entry as a trespasser into a building or part of a building with intent to commit theft, GBH or unlawful damage. Under s.9(1)(b), having entered as a trespasser, the defendant actually commits (or attempts) theft or GBH. Conditional intent suffices.
入室盗窃第9(1)(a)条：以侵入者身份进入建筑物或其一部分，意图实施盗窃、严重身体伤害或非法损毁。第9(1)(b)条：以侵入者身份进入后，实际实施（或意图）盗窃或严重身体伤害。附条件的意图即可满足。
7. Negligence: Duty of Care – The Caparo Tripartite Test | 过失侵权：注意义务的 Caparo 三步检验
In tort law, negligence transforms careless conduct into liability only when a duty of care exists. The modern general test was established in Caparo Industries plc v Dickman.
在侵权法中，只有存在注意义务时，疏忽行为才会转化为责任。现代通用检验标准确立于 Caparo Industries plc v Dickman 案。
Foreseeability + Proximity + Fair, just and reasonable = Duty of Care
可预见性 + 近邻关系 + 公平、公正且合理 = 注意义务
Foreseeability asks whether the claimant was a foreseeable victim of the defendant’s carelessness. Proximity may be physical, relational, or causal. The third limb ensures that imposing a duty aligns with policy considerations and does not open the floodgates to indeterminate claims.
可预见性考察原告是否是被告疏忽行为可预见的受害人。近邻关系可以是物理的、关系的或因果的。第三步确保施加义务符合政策考量，不会打开不确定索赔的闸门。
Established duty situations (e.g., road users, doctor‑patient) require no Caparo analysis. For novel situations, courts apply the three‑stage test incrementally and by analogy with precedents (Robinson v Chief Constable of West Yorkshire Police).
已有的注意义务情境（如道路使用者、医患关系）无需进行 Caparo 分析。在新情境下，法院以渐进和类比先例的方式适用三阶段检验（Robinson 案）。
8. Breach of Duty, Causation & Remoteness | 违反注意义务、因果关系与损害遥远性
Once a duty exists, the claimant must prove the defendant fell below the standard of the reasonable person. The classic test is: did the defendant do something a reasonable person would not have done, or omit to do something a reasonable person would have done (Blyth v Birmingham Waterworks)?
一旦注意义务存在，原告必须证明被告的行为低于合理人的标准。经典检验是：被告是否做了合理人不会做的事，或没做合理人会做的事（Blyth 案）？
Special standards apply: professionals are judged by the ordinary competent practitioner in that field (Bolam; modified by Bolitho), children by the reasonable child of comparable age (Mullin v Richards), and learners by the standard of the competent, experienced person (Nettleship v Weston).
特殊标准适用：专业人员按其领域内普通胜任的执业者标准判断（Bolam 案，经 Bolitho 修正），儿童以同龄合理儿童为标准（Mullin 案），学员以胜任且有经验者的标准判断（Nettleship 案）。
‘But for’ cause + Legal cause (more than minimal) + No effective intervening act = Causation
“若非”致因 + 法律致因（超出微小） + 无有效介入行为 = 因果关系成立
Remoteness of damage is governed by the Wagon Mound test: the defendant is liable only for damage of a type that was reasonably foreseeable, though the extent need not be foreseen. The ‘egg‑shell skull’ rule means a defendant takes the claimant as found, even if unforeseeable pre‑existing conditions worsen the harm.
损害遥远性遵循 Wagon Mound 标准：被告仅对可合理预见的那类损害负责，但损害程度无需预见。“蛋壳头骨”规则意味着被告须按原告的现有状况承担责任，即使不可预见的原有状况加重了伤害。
9. Occupiers’ Liability: Visitors & Trespassers | 占用人责任：访客与入侵者
Two statutes govern the duty owed by occupiers of premises. The Occupiers’ Liability Act 1957 protects lawful visitors, while the Occupiers’ Liability Act 1984 extends limited protection to trespassers.
两项制定法规管占用人对场所使用者的义务。《1957年占用人责任法》保护合法访客，《1984年占用人责任法》给予入侵者有限保护。
OLA 1957 (visitors): Occupier + Common duty of care + Reasonable care in all circumstances
1957年法（访客）：占用人 + 普通注意义务 + 在所有情形下采取合理注意
The occupier (someone with sufficient control) must see that the visitor is reasonably safe for the purposes of their visit (s.2(2)). A warning may discharge the duty unless it falls short. Skilled visitors can be expected to guard against special risks reasonably incidental to their calling (s.2(3)(b)). Children must be protected with a higher degree of care because they are less careful (s.2(3)(a) – Glasgow Corp v Taylor).
占用人（具有足够控制权的人）必须保证访客为其访问目的而处于合理安全状态（第2(2)条）。警告可以解除义务，除非不够充分。熟练专业人士应自行防范其职业范围内通常附带的风险（第2(3)(b)条）。儿童需受到更高程度的保护，因为他们不够谨慎（第2(3)(a)条 – Glasgow Corp 案）。
OLA 1984 (trespassers): Occupier + Aware of danger + Aware of risk of presence + Reasonable to protect = Limited Duty
1984年法（入侵者）：占用人 + 知晓危险 + 知晓他人可能身处附近 + 合理要求提供保护 = 有限义务
Under the 1984 Act the occupier must have reasonable grounds to believe the danger exists and that a trespasser may come into the vicinity, and the risk must be one against which the occupier should reasonably offer protection (s.1(3)). The duty may be discharged by warnings or discouragement (s.1(5)).
依1984年法，占用人必须有合理理由相信危险存在且有入侵者可能进入附近，并且该风险属于应合理提供保护的风险（第1(3)条）。通过警告或阻止可解除该义务（第1(5)条）。
10. Vicarious Liability & Tort Defences | 替代责任与侵权抗辩
Vicarious liability makes an employer strictly liable for torts committed by an employee in the course of employment. The modern test looks at whether the relationship is akin to employment and whether the wrongful conduct was closely connected to it.
替代责任使雇主对雇员在雇佣过程中实施的侵权行为承担严格责任。现代检验标准考察该关系是否类似于雇佣关系，以及不法行为是否与之紧密关联。
Relationship akin to employment + Tort + Close connection = Vicarious Liability
类似雇佣关系 + 侵权行为 + 紧密关联性 = 替代责任
The Supreme Court in Cox v Ministry of Justice identified five non‑exhaustive criteria: the employer’s activity likely to cause harm, the tortfeasor’s activity integrated into the employer’s organisation, and the enterprise creating the risk. Even deliberate criminal acts can be ‘in the course of employment’ if there is a sufficiently close connection (Mohamud v WM Morrison Supermarkets).
最高法院在 Cox 案中提出五项非穷尽标准：雇主活动可能造成伤害、侵权人的活动已融入雇主组织，以及企业创造了风险。即使是故意犯罪行为，只要与雇佣有足够紧密的关联，也可认定为“在雇佣过程中”（Mohamud 案）。
Key tort defences also function as ‘subtractions’ from liability. Volenti non fit injuria (consent) is a complete defence where the claimant freely and fully accepted the risk. Illegality (ex turpi causa) bars claims founded on the claimant’s own illegal act. Contributory negligence reduces damages proportionately where the claimant’s own carelessness contributed to the damage (Law Reform (Contributory Negligence) Act 1945).
关键侵权抗辩也充当责任的“减法”。自愿接受风险（volenti）是当原告自由且完全接受风险时的完全抗辩。违法性（ex turpi causa）禁止基于原告自身非法行为的索赔。共同过失（《1945年法律改革（共同过失）法》）在原告自身疏忽对损害有贡献时按比例减少赔偿额。
11. Human Rights: Key Articles & Limitations | 人权：关键条款与限制
The Human Rights Act 1998 incorporates the European Convention on Human Rights into domestic law. Articles can be categorised as absolute, limited or qualified, which determines whether a public authority can lawfully interfere.
《1998年人权法》将《欧洲人权公约》纳入国内法。条款可分为绝对权利、有限权利和受限权利，这决定了公共机构是否可以合法干涉。
Article 2 – Right to life: Absolute (with limited exceptions defining when state‑caused death is justified)
第2条 – 生命权：绝对权利（但特定情形下国家造成的死亡可被正当化）
Article 3 – Prohibition of torture, inhuman/degrading treatment: Absolute
第3条 – 禁止酷刑、不人道或有辱人格的待遇：绝对权利
Article 5 – Right to liberty and security: Limited (exhaustive list of permitted detentions)
第5条 – 自由与安全权：有限权利（详尽的允许拘留清单）
Articles 8, 9, 10, 11 – Qualified rights: Interference lawful if prescribed by law, for a legitimate aim, and necessary in a democratic society
第8、9、10、11条 – 受限权利：干涉合法须满足法律规定、具有合法目的且为民主社会所必需
Article 8 (private and family life) and Article 10 (freedom of expression) are frequently balanced in case law. The proportionality test asks whether the restriction corresponds to a pressing social need and is proportionate to the aim pursued. Remember that s.2 HRA 1998 requires UK courts to ‘take into account’ Strasbourg jurisprudence, and s.3 imposes an interpretative duty to read legislation compatibly as far as possible.
