1. Criminal Liability Formula | 刑事责任公式
The fundamental equation of crime:
Guilt = Actus Reus (AR) + Mens Rea (MR) - Defence
Actus reus is the guilty act — the physical element, which can be an act, omission (where a duty exists), or a state of affairs. Mens rea is the guilty mind — the mental element, such as intention, recklessness, or negligence. For a conviction, the prosecution must prove both AR and MR beyond reasonable doubt, and the defendant must have no valid defence (e.g., self‑defence, insanity). If any element is missing, the equation fails and liability is not established. This foundational formula underpins all criminal offences, from murder to theft.
犯罪行为（actus reus）是犯罪客观要素——可以是作为、不作为（当存在义务时）或特定状态。犯罪意图（mens rea）是主观要素，如故意、轻率或过失。定罪需控方排除合理怀疑地证明 AR 与 MR 并存，且被告不存在有效抗辩（如自我防卫、精神错乱）。任一要素缺失，等式即不成立，刑事责任无法确立。这一基础公式支撑着从谋杀到盗窃的所有刑事犯罪。
The formula also explains strict liability offences, where MR is not required for at least one element of the AR. Here the equation simplifies to AR + no defence, shifting focus onto the act alone. Key case: Sweet v Parsley (1970) — presumption of MR unless statute clearly excludes it.
该公式也解释了严格责任犯罪——犯罪行为的至少一个要素无需证明犯罪意图。此时公式简化为 AR + 无抗辩，重点落在行为本身。关键判例：Sweet v Parsley (1970) 确立，除非法条明确排除，否则推定需要犯意。
2. Murder | 谋杀罪公式
= Unlawful Killing of a Human Being + Malice Aforethought (Intention to Kill or Cause GBH)
Murder is a common law offence. The actus reus requires the unlawful killing of a reasonable person in being under the Queen's (now King's) peace. The mens rea is malice aforethought, which means an intention to kill or to cause grievous bodily harm (GBH). This is a specific intent offence: recklessness is not enough. The defendant must have a direct or oblique intention — where death or GBH was a virtual certainty and the defendant appreciated that fact (R v Woollin 1999). Life imprisonment is the mandatory sentence upon conviction.
谋杀是普通法犯罪。犯罪行为要求非法杀害一个有理性的人（在国王治下）。犯意为恶意预谋，即具有杀人或造成严重身体伤害（GBH）的故意。这是特定故意犯罪：轻率不足以构成。被告须有直接或间接故意——即死亡或 GBH 是实质上确定的结果且被告认识到该事实（R v Woollin 1999）。定罪后强制判处终身监禁。
3. Voluntary Manslaughter: Loss of Control & Diminished Responsibility | 自愿非预谋杀人：失控与减轻责任
Voluntary Manslaughter = Murder – Partial Defence (Loss of Control or Diminished Responsibility)
Voluntary manslaughter arises when a defendant would be liable for murder but successfully raises a partial defence, reducing the conviction from murder to manslaughter. The two key partial defences under the Coroners and Justice Act 2009 are loss of control and diminished responsibility.
自愿非预谋杀人指被告本应构成谋杀，但成功主张部分抗辩，将定罪从谋杀减为非预谋杀。根据2009年《验尸官与司法法》，两个关键部分抗辩是失控与减轻责任。
Loss of Control Formula: (1) D lost self‑control due to a qualifying trigger (fear of serious violence; things said/done of extremely grave character giving justifiable sense of being seriously wronged; or combination). (2) A person of D’s sex and age, with normal tolerance and in the same circumstances, might have reacted similarly (R v Clinton 2012). Sexual infidelity alone is excluded as a trigger, but can be considered alongside other factors.
失控公式：(1) 被告因适格触发因素（对严重暴力的恐惧；性质极其严重且使被告产生合理严重委屈感的事由；或两者结合）而失控。(2) 与被告同性别、同龄、具有正常容忍度且处于相同情境的人可能作出类似反应（R v Clinton 2012）。仅性不忠被排除为触发因素，但可结合其他因素考量。
Diminished Responsibility Formula: (1) Abnormality of mental functioning arising from a recognised medical condition. (2) Which substantially impaired D’s ability to understand the nature of their conduct, form a rational judgment, or exercise self‑control. (3) And provides an explanation for the killing. The burden of proof lies on D on the balance of probabilities (R v Byrne 1960, R v Golds 2016).
减轻责任公式：(1) 因被认可的医疗状况导致精神功能异常。(2) 该异常实质性损害了被告理解自身行为性质、形成理性判断或行使自控的能力。(3) 并为杀人行为提供解释。举证责任在被告，标准是或然性权衡（R v Byrne 1960, R v Golds 2016）。
4. Involuntary Manslaughter: Unlawful Act & Gross Negligence | 非自愿非预谋杀人：非法行为与重大过失
Unlawful Act Manslaughter = Unlawful Act + Dangerous (Risk of Some Harm) + Causes Death
Also known as constructive manslaughter, this formula requires a base criminal offence (not negligence or omission). The act must be objectively dangerous — a sober and reasonable person would recognise the risk of some physical harm (R v Church 1966). The act must cause death; the defendant need not foresee death or serious harm. No additional mens rea for the death is required, as MR for the base offence suffices. Example: a punch causing victim to fall and fatally hit head qualifies if the punch was unlawful and dangerous.
又称推定非预谋杀，此公式要求存在基础刑事犯罪（非过失或不作为）。该行为必须在客观上具有危险性——清醒的理性人会认识到存在某些身体伤害的风险（R v Church 1966）。行为须导致死亡；被告无需预见死亡或严重伤害。对死亡无需额外犯意，基础犯罪的犯意足矣。例如一拳击打致被害人摔倒并致命撞击头部，若拳击非法且危险，即构成。
ence Manslaughter = Duty of Care + Breach Causing Risk of Death + Gross Negligence + Death
The defendant must owe a duty of care (ordinary tort negligence principles, R v Adomako 1994). The breach must create a risk of death — not merely of harm. The negligence must be 'gross', meaning so severe as to be criminal, going beyond mere civil carelessness and showing disregard for life and safety (R v Bateman 1925). The breach must cause death. Medical professionals, employers, and even family members may be liable under this formula.
被告须负有注意义务（依据一般侵权过失原则，R v Adomako 1994）。违反义务须造成死亡风险——而不仅是伤害风险。过失须“重大”，即严重至构成刑事，超越单纯民事疏忽，显示对生命与安全的漠视（R v Bateman 1925）。违反行为须导致死亡。医护人员、雇主乃至家庭成员均可依此公式承担责任。
5. Non‑Fatal Offences: Assault, Battery, ABH, GBH | 非致命犯罪：恐吓、殴打、实际身体伤害、严重身体伤害
ult = Intentional/Reckless Act Causing V to Apprehend Immediate Unlawful Personal Violence
Assault is a summary offence. No physical contact is needed; words can suffice (R v Ireland 1997 — silent phone calls). The victim must apprehend immediate force, though ‘immediacy’ is interpreted broadly. Mens rea is intention or subjective recklessness. Fear is not required — just the expectation of force.
恐吓是即决犯罪，无需身体接触；言语可构成（R v Ireland 1997 — 无声电话）。被害人须担忧即将受侵害，但“即将”作广义解释。犯意为故意或主观轻率。恐惧并非要件——仅需预想到侵害。
Battery = Intentionally/Recklessly Applying Unlawful Force to V
Battery involves the slightest touching without consent, even via an object. Force must be direct or indirect (e.g., setting a trap). It can be reckless. Everyday jostling not included (implied consent). Cole v Turner (1704) — the least touching in anger is battery.
殴打涉及未经同意的轻微碰触，即便通过物体。力量须直接或间接（如设陷阱）。可出于轻率。日常碰撞不在其中（默示同意）。Cole v Turner (1704) — 愤怒中的极轻微碰触即构成殴打。
Assault Occasioning ABH = Assault or Battery + Actual Bodily Harm
Section 47 Offences Against the Person Act 1861. ABH means harm that is more than transient or trifling, including psychiatric injury (R v Miller 1954). Causation required. MR is the same as for the underlying assault or battery — no need to intend or foresee ABH.
1861年《人身犯罪法》第47条。ABH指超出一时或微不足道的伤害，包括精神伤害（R v Miller 1954）。需因果关系。犯意与基础恐吓或殴打相同——无需故意或预见ABH。
/Inflicting GBH (s.20) = Unlawful Wounding or GBH + Intention/Recklessness as to Some Harm
GBH means 'really serious harm' (DPP v Smith 1961). Wounding requires a break in the continuity of the whole skin. MR is intention or recklessness as to some harm, not necessarily serious. Section 20 carries up to 5 years imprisonment.
GBH指“真正严重伤害”（DPP v Smith 1961）。创伤需全层皮肤断裂。犯意为对某些伤害的故意或轻率，不要求严重。第20条最高刑期5年。
g/Causing GBH with Intent (s.18) = s.20 AR + Specific Intent to Cause GBH or Resist Arrest
The most serious non‑fatal offence. AR same as s.20 — wounding or GBH. MR is specific intention to cause GBH, or intent to resist/prevent lawful arrest AND causing GBH recklessly. Maximum life imprisonment.
最严重的非致命犯罪。犯罪行为同第20条——创伤或GBH。犯意为造成GBH的特定故意，或意图抗拒/阻止合法逮捕且轻率造成GBH。最高可判终身监禁。
6. Property Offences: Theft, Robbery, Burglary | 财产犯罪：盗窃、抢劫、入室盗窃
onest Appropriation of Property Belonging to Another with Intention to Permanently Deprive
Theft Act 1968, s.1–6. All five elements must be proven. Appropriation includes assuming any rights of the owner, even with consent if later found dishonest (R v Gomez 1993). Property includes money, things in action, intangible property. Belonging to another is widely construed. Dishonesty is judged by the Ivey v Genting (2017) test: (1) What was D’s actual knowledge or belief as to the facts? (2) Was D’s conduct dishonest by the standards of ordinary decent people? No need for D to realise the dishonesty. Intent to permanently deprive includes treating the thing as one’s own regardless of owner’s rights.
1968年《盗窃法》第1-6条。五要素须全部证明。侵占包括行使所有者的任何权利，即便有同意但后被认定不诚实（R v Gomez 1993）。财产包括金钱、权利动产、无形财产。属于他人作广义解释。不诚实性依Ivey v Genting (2017)标准判断：(1) 被告对事实的实际认知或信念？(2) 按普通正直人的标准，被告行为是否不诚实？无需被告自认不诚实。永久剥夺意图包括不顾所有者权利将物视为己有。
Robbery = Theft + Force or Threat of Force Immediately Before or at the Time of Stealing
Theft Act 1968, s.8. If no theft is completed, no robbery — thus all theft elements are required. The force or threat must be used in order to steal. Force on anyone, not just the property holder. Timing is crucial: force must be immediately before or at the time of stealing.
1968年《盗窃法》第8条。若未完成盗窃，则无抢劫——因此盗窃全部要件均需满足。武力或威胁须为实施盗窃而使用。可针对任何人，非仅财物持有者。时机关键：武力须在盗窃前夕或同时。
Burglary = Entry into a Building/Trespass + with Intent/Mens Rea Specified in s.9
Burglary under s.9 has two variants. s.9(1)(a): Entry as trespasser with intent to commit theft, GBH, or criminal damage. s.9(1)(b): Entry as trespasser and then actually commits (or attempts) theft or GBH. Entry must be effective and substantial (R v Brown 1985), though any body part suffices. Building includes inhabited vehicles or vessels, and even large containers. Must know or be reckless as to trespass.
第9条入室盗窃有两种形态。s.9(1)(a)：以非法侵入者身份进入且有意图实施盗窃、GBH或刑事毁坏。s.9(1)(b)：以侵入者身份进入并随后实际实施（或企图）盗窃或GBH。进入须有效且实质性（R v Brown 1985），但任何身体部分即足。建筑物包括有人居住的车辆或船只，甚至大型货柜。须对侵入知情或轻率。
7. Negligence: The Tort Formula | 过失侵权公式
Negligence = Duty of Care + Breach of Duty + Causation (Factual & Legal) + Damage
Established in Donoghue v Stevenson (1932), the modern duty of care uses the Caparo v Dickman (1990) three‑part test: (1) Reasonable foreseeability of harm to this claimant; (2) Proximity of relationship (including physical, circumstantial, or causal proximity); (3) Fair, just and reasonable to impose a duty. Once duty exists, breach is assessed by the objective standard of the reasonable person (Blyth v Birmingham Waterworks 1856), adjusted for special characteristics (e.g., children, professionals). Professionals are judged by the standard of their profession (Bolam v Friern HMC 1957), modified by Bolitho. Factual causation asks 'but for' the breach, would the damage have occurred? (Barnett v Chelsea Hospital). Legal causation considers whether the damage is too remote — the type of damage must be reasonably foreseeable (The Wagon Mound (No 1)). Any intervening act may break the chain. Damage must be a recognised loss (personal injury, property damage, psychiatric harm under certain conditions).
确立于 Donoghue v Stevenson (1932)，现代注意义务依 Caparo v Dickman (1990) 三步检验：(1) 对该权利人伤害的可合理预见性；(2) 关系邻近性（身体、情势或因果邻近）；(3) 施加义务公平、公正与合理。义务成立后，违反以客观理性人标准判断（Blyth v Birmingham Waterworks 1856），并根据特殊特征调整（如儿童、专业人士）。专业人士适用同行标准（Bolam v Friern HMC 1957），经 Bolitho 修正。事实因果采“若非”检验——若无违反，损害是否仍会发生？（Barnett v Chelsea Hospital）。法律因果考量损害是否过于遥远——损害类型须可合理预见（The Wagon Mound (No 1)）。任何介入行为可中断因果关系链。损害须为法律承认的损失（人身伤害、财产损害、特定条件下的精神伤害）。
8. Occupiers’ Liability | 占用人责任公式
ity Act 1957 (Visitors) = Occupier + Visitor + Common Duty of Care + Breach Causing Damage
An occupier is someone who has sufficient control over premises (Wheat v Lacon 1966). Visitors are those with express or implied permission, including invitees and licensees. The common duty is to 'take such care as in all the circumstances is reasonable to see that the visitor will be reasonably safe in using the premises for the purpose for which he is invited' (s.2(2)). Special regard for children who may be less careful, and for tradesmen exercising their calling. Warnings can discharge the duty if adequate. Independent contractors: occupier must ensure reasonable care in their work, unless it is technical and reasonable to entrust to a specialist. Defences include volenti and contributory negligence.
占用人指对场所具有足够控制力者（Wheat v Lacon 1966）。访客为有明示或默示许可者，包括受邀人和被许可人。一般义务是“在所有情况下采取合理注意确保访客为其被邀请的目的使用场所时合理安全”（s.2(2)）。特别考虑儿童可能较不谨慎，以及从业者行使职业。警告若足够可解除义务。独立承包人：占用人须合理注意其工作，除非工作技术性强且交于专家合理。抗辩包括自愿承担风险与共同过失。
respasser + Aware of Danger + Risk of Injury on Premises + Failure to Take Reasonable Care
A duty is owed only if the occupier is aware of the danger (or has reasonable grounds to believe it exists); knows or has reasonable grounds to believe a trespasser might come into the vicinity; and the risk is one against which, in all the circumstances, the occupier may reasonably be expected to offer some protection. The duty is to take such care as is reasonable to see that the trespasser does not suffer injury on the premises by reason of the danger concerned. Warnings may suffice. No liability for property damage towards trespassers. This is a lesser duty than that owed to visitors.
仅在以下情形负有义务：占用人知悉危险（或有合理理由相信其存在）；明知或有合理理由相信侵入者可能进入该区域；且依全部情势，合理期待占用人提供某些保护。义务是采取合理注意确保侵入者不因该危险而在场所内受伤。警告可能足够。对侵入者的财产损害不负责任。此义务低于对访客的义务。
9. Private Nuisance | 私人妨害公式
Private Nuisance = Unreasonable Interference with C's Use or Enjoyment of Land + Resulting Damage
Private nuisance protects an occupier’s interest in the beneficial use of land. The interference must be unreasonable, judged by factors including: duration, frequency, locality, sensitivity of claimant, malice of defendant, and public benefit (Sturges v Bridgman 1879, Christie v Davey 1893). Physical damage to property is easier to establish than personal discomfort. The claimant must have a proprietary interest in the land (Malone v Laskey 1907). Defences include prescription (20 years continuous lawful activity), and statutory authority. Coming to the nuisance is no defence.
私人妨害保护占用人对土地有益使用的权益。干涉必须不合理，判断需考量：时长、频率、地点特性、权利人敏感性、被告恶意及公共利益（Sturges v Bridgman 1879, Christie v Davey 1893）。财产的物质损害比人身不舒适更易成立。原告须对土地拥有财产权益（Malone v Laskey 1907）。抗辩包括时效（20年持续合法活动）和法定授权。主动接近妨害不构成抗辩。
10. The Rule of Law & Judicial Review Formula | 法治与司法审查公式
f Law ≈ No Arbitrary Power + Legal Certainty + Equality Before the Law + Access to Justice
Dicey’s core principles (modified today) underpin the UK constitution: no one can be punished except for a breach of law; everyone is subject to the ordinary law administered by ordinary courts; and constitutional rights derive from judicial decisions. While modern critiques highlight Parliamentary sovereignty tensions, the formula remains a benchmark for justice. Judicial review ensures public bodies act lawfully, rationally, fairly, and compatibly with human rights.
戴西的核心原则（经现代修正）构成英国宪法基础：非经法律违犯，无人可受惩罚；人人受普通法院执行的普通法律管辖；宪法权利来源于司法判决。尽管现代批评指出与议会主权的张力，该公式仍是正义标尺。司法审查确保公共机构合法、理性、公平且符合人权地行事。
11. Statutory Interpretation Formula | 成文法解释公式
Construction = Word Meaning + Context + Purpose + Presumptions + External Aids
Judges deploy rules and aids. Literal rule gives words their plain, ordinary meaning (Fisher v Bell 1961). Golden rule allows departure from literal meaning to avoid absurdity (R v Allen 1872, Re Sigsworth 1935). Mischief rule examines the defect the statute was intended to remedy (Heydon’s Case 1584). Purposive approach looks at the broader purpose of the legislation, especially post‑EU law and Human Rights Act 1998 contexts (Pepper v Hart 1993 permits reference to Hansard). Presumptions include against alteration of common law, against retrospective effect, and in favour of compliance with international treaties.
法官适用规则与辅助手段。文义规则赋予词语通常平义（Fisher v Bell 1961）。黄金规则允许偏离文义以避免荒谬（R v Allen 1872, Re Sigsworth 1935）。弊端规则探究成文法旨在弥补的缺陷（Heydon’s Case 1584）。目的解释法关注立法的更广泛目的，尤在后欧盟法与1998年《人权法》背景下（Pepper v Hart 1993 允许参考议会议事录）。推定包括不改变普通法、不溯及既往及遵守国际条约。
12. Judicial Precedent Formula | 司法先例公式
Binding Precedent = Ratio Decidendi + Material Facts + Court Hierarchy
The ratio decidendi is the legal principle which forms the basis of the decision — the reason for deciding. Only decisions of superior courts bind lower courts. The Supreme Court binds all below but may depart from its own precedent under the 1966 Practice Statement. The Court of Appeal is bound by its own decisions unless an exception applies (Young v Bristol Aeroplane 1944). Persuasive precedent includes obiter dicta, decisions of lower courts, and foreign judgments. Distinguishing on material facts allows courts to avoid an otherwise binding precedent. Overruling removes a precedent; reversing changes the decision on appeal.
判决理由（ratio decidendi）是构成判决基础的法律原则——裁决的理由。只有上级法院的判决约束下级法院。最高法院约束所有下级，但依1966年实践声明可背离自身先例。上诉法院受自身判决约束，除非存在例外（Young v Bristol Aeroplane 1944）。有说服力的先例包括附带意见、下级法院判决及外国判决。对关键事实的区分允许法院避开本应约束的先例。推翻（overruling）消灭先例；改判（reversing）指上诉时改变决定。
