📚 Year 11 AQA Law: Quick Reference Handbook of Formulas and Theorems | Year 11 AQA 法律：公式定理速查手册

In AQA GCSE Law, you are not asked to memorise mathematical equations, but rather a series of legal 'formulas' that help you deconstruct criminal and civil liability. Each legal rule can be expressed as a combination of essential elements (actus reus, mens rea, duty, breach, causation, and defences). This quick reference handbook transforms key legal principles into structured formulas and theorems, giving you a powerful toolkit for exam success. Keep these formulas at your fingertips as you revise for Paper 1 and Paper 2, and remember that each component must be fully defined and supported by case law.

在AQA GCSE法律课程中，你不需要记忆数学方程式，而是要掌握一系列法律“公式”，用于分解刑事责任与民事责任。每一条法律规则都可以表达为基本要件（犯罪行为、犯罪心理、注意义务、违反义务、损害、因果关系和抗辩理由）的组合。这份速查手册将关键法律原则转化为结构化的公式与定理，为你提供考试成功的强大工具箱。复习试卷一和试卷二时，请将这些公式熟记于心，并牢记每个组成部分都需要给出完整定义，并以判例法加以佐证。

1. The Murder Formula | 谋杀罪公式

Murder is the most serious homicide offence. The basic formula is: Murder = Unlawful Killing + Intent to Kill or Cause GBH – Valid Defence. The actus reus requires the unlawful killing of a reasonable creature in being under the King's Peace. The victim must be a human being who was alive and breathing independently (AG's Reference No. 3 of 1994). The mens rea is an intention to kill or cause grievous bodily harm (GBH). Direct intent (aim or purpose) and oblique intent (virtual certainty as in R v Woollin) both satisfy this element. Partial defences such as diminished responsibility or loss of control may reduce murder to voluntary manslaughter.

谋杀是最严重的杀人罪。基本公式为：谋杀 = 非法杀人 + 意图杀人或造成重伤 – 有效抗辩。犯罪行为要求是在国王治下非法杀害一个有理性的人。被害人必须是在独立存活和呼吸的人（AG's Reference No. 3 of 1994）。犯罪心理是意图杀人或造成重伤。直接故意（目的或目标）和间接故意（如R v Woollin案中的近乎必然）都满足这一要件。减免责任或失控等部分抗辩可将谋杀减轻为自愿非预谋杀人。

Actus Reus (unlawful killing of a human) + Mens Rea (intention to kill or cause GBH) – Diminished Responsibility/Loss of Control = Voluntary Manslaughter

犯罪行为（非法杀人）+ 犯罪心理（意图杀人或致重伤）– 减免责任/失控 = 自愿非预谋杀人

2. The Theft Formula | 盗窃罪公式

The Theft Act 1968, s.1 defines theft. The formula can be written as: priation + Property + Belonging to Another + Dishonesty + Intention to Permanently Deprive. Appropriation means any assumption of the rights of an owner (R v Morris). Property includes money, personal items, and intangible property. The property must belong to another; you cannot steal your own property unless another has a proprietary interest (R v Turner No.2). Dishonesty is judged by the common standard of ordinary decent people (Ivey v Genting Casinos), and the defendant must intend never to return the property (permanent deprivation). If any element is missing, no theft.

《1968年盗窃法》第1条定义了盗窃罪。公式可以写作：盗窃 = 侵占 + 财产 + 属于他人 + 不诚实 + 意图永久剥夺。侵占指任何行使所有权人权利的行为（R v Morris）。财产包括货币、个人物品及无形财产。该财产必须属于他人；你不能盗窃自己的财产，除非他人对该财产也享有权益（R v Turner No.2）。不诚实应根据普通正直人士的通常标准进行判断（Ivey v Genting Casinos），被告人还必须具有永不归还财产的意图（永久剥夺）。若缺少任一要件，盗窃罪不成立。

roperty + Belonging to Another) + s.2(1) Dishonesty + s.6 Intention to Permanently Deprive

盗窃 = 1968年盗窃法第1条（侵占 + 财产 + 属于他人）+ 第2条第1款不诚实 + 第6条意图永久剥夺

3. The Assault and Battery Formulas | 恐吓与殴打公式

Assault and battery are separate common law offences. The formula for assault is: Assault = Act Causing Apprehension of Immediate Unlawful Force + Intention or Recklessness. No physical contact is required; words or silent phone calls can suffice (R v Ireland). Battery requires unlawful physical contact: Battery = Application of Unlawful Force + Intention or Recklessness. The force need not be hostile; any unwanted touching may qualify (Collins v Wilcock). For both, recklessness means the defendant foresaw the risk of the prohibited result and took it (R v Cunningham subjective test). Assault occasioning actual bodily harm (ABH) under s.47 OAPA 1861 uses the formula: Assault + Battery + Occasioning + ABH.

恐吓与殴打是两种不同的普通法犯罪。恐吓的公式是：恐吓 = 引起对即时非法暴力的忧虑的行为 + 故意或轻率。无需发生身体接触；言语或沉默电话亦可满足（R v Ireland）。殴打则要求非法身体接触：殴打 = 施加非法暴力 + 故意或轻率。暴力无须具有敌意；任何不情愿的触碰都可能构成殴打（Collins v Wilcock）。对两者而言，轻率是指被告人预见到被禁止结果的风险并甘冒该风险（R v Cunningham主观标准）。《1861年侵害人身罪法》第47条规定的恐吓致实际身体伤害（ABH）的公式为：恐吓 + 殴打 + 导致 + 实际身体伤害。

s.47 ABH = Common Assault + Battery + 'Occasioning' + Actual Bodily Harm (Miller)

第47条实际身体伤害 = 普通恐吓 + 殴打 + “导致” + 实际身体伤害（Miller案）

4. The Negligence Formula | 过失侵权公式

The tort of negligence is built on a neat formula: Negligence = Duty of Care + Breach of Duty + Damage + Causation. First, establish a duty of care using the Caparo three-part test: foreseeable harm, proximity, and whether it is fair, just and reasonable to impose a duty (Caparo Industries v Dickman). Next, breach of duty is measured by the objective standard of the reasonable person (Blyth v Birmingham Waterworks); special standards apply for professionals (Bolam test) and children (Mullin v Richards). The claimant must then prove that the breach caused the damage, both in fact ('but for' test, Barnett v Chelsea & Kensington Hospital) and in law (damage not too remote, The Wagon Mound). Finally, the type of damage must be recognised (personal injury, property damage, psychiatric harm in some cases).

过失侵权建立在一条简洁的公式之上：过失 = 注意义务 + 违反义务 + 损害 + 因果关系。首先，用Caparo三阶检验确定注意义务：可预见的损害、紧密关联性，以及施加义务是否公平、公正和合理（Caparo Industries v Dickman）。其次，违反义务以客观的理性人标准衡量（Blyth v Birmingham Waterworks）；对专业人士（Bolam检验）和儿童（Mullin v Richards）适用特别标准。接着，索赔人必须证明违反义务导致了损害，包括事实上（“若非”检验，Barnett v Chelsea & Kensington Hospital）和法律上（损害不能过于遥远，The Wagon Mound）。最后，损害类型必须是可获承认的（人身伤害、财产损失，某些情形下的精神损害）。

Negligence Liability = (Duty: Caparo) + (Breach: Reasonable Person) + (Factual Causation: 'But for') + (Legal Causation: Not Too Remote) + Recognised Damage

过失责任 = （义务：Caparo） + （违反：理性人） + （事实因果关系：“若非”） + （法律因果关系：不遥远） + 可承认的损害

5. The Occupiers' Liability Formula | 占有人责任公式

Under the Occupiers' Liability Act 1957, lawful visitors are owed a common duty of care. The formula is: Occupier's Liability = Occupier + Premises + Visitor + Common Duty Breach + Damage. An occupier is anyone with sufficient control over the premises (Wheat v E Lacon). The common duty of care requires the occupier to take reasonable steps to see that the visitor is reasonably safe (OLA 1957, s.2(2)). Special care is owed to children (Glasgow Corp v Taylor) and persons exercising their trade (roles v Nathan). Warning signs may discharge the duty if adequate. Under the OLA 1984, reduced protection applies to trespassers, with a triple test: awareness of danger, knowledge of likely presence, and a failure to take reasonable steps.

按照《1957年占有人责任法》，合法访客享有一般注意义务。公式为：占有人责任 = 占有人 + 场所 + 访客 + 违反一般注意义务 + 损害。占有人指对场所拥有足够控制权的任何人（Wheat v E Lacon）。一般注意义务要求占有人采取合理措施确保访客合理安全（1957年占有人责任法第2条第2款）。对儿童（Glasgow Corp v Taylor）和从事本行业工作的人（roles v Nathan）应给予特殊照顾。警示标志若足够充分，可免除义务。按照《1984年占有人责任法》，侵入者受到较低程度保护，适用三重检验：知晓危险、知晓侵入者可能出现、未采取合理措施。

itor Safety; OLA 1984: Duty = (Awareness of Danger + Likely Presence + No Reasonable Care)

1957年法：义务 = （控制 + 场所）× 为访客安全采取合理措施；1984年法：义务 = （知晓危险 + 可能出现 + 未合理谨慎）

6. The Contract Formation Formula | 合同成立公式

A contract is formed when the core elements align: Contract = Offer + Acceptance + Consideration + Intention to Create Legal Relations. An offer is a definite promise to be bound on specific terms, distinguished from an invitation to treat (Fisher v Bell). Acceptance must mirror the offer exactly, be communicated (except for postal rule, Adams v Lindsell), and be made while the offer is still alive. Consideration is the 'price of the promise'; it must be sufficient but need not be adequate (Thomas v Thomas), and past consideration is not valid (Re McArdle). The parties must intend legal consequences; for social and domestic arrangements there is a presumption against legal intent (Balfour v Balfour), while commercial agreements carry a strong presumption for intent (Esso Petroleum v Commissioners of Customs and Excise).

合同在核心要件齐备时成立：合同 = 要约 + 承诺 + 对价 + 建立法律关系的意图。要约是有意受特定条款约束的明确允诺，须与要约邀请相区别（Fisher v Bell）。承诺必须与要约完全一致、必须作出传达（邮政规则除外，Adams v Lindsell），且须在要约有效存续期间作出。对价是“承诺的代价”；必须充分但无需对等（Thomas v Thomas），过去的对价无效（Re McArdle）。双方须意图产生法律后果；对于社交及家庭安排，存在法律意图不成立的推定（Balfour v Balfour），而商业协议则强烈推定存在法律意图（Esso Petroleum v Commissioners of Customs and Excise）。

s) + Acceptance (unconditional mirror) + Consideration (sufficient, not past) + Intention (rebuttable presumptions)

广告 / Sponsored

有约束力的合同 = 要约（条款明确） + 承诺（无条件镜像） + 对价（充分、非过去） + 意图（可反驳的推定）

7. The Criminal Defences: Self-Defence and Insanity Formulas | 刑事抗辩：自卫与精神错乱公式

Even if the actus reus and mens rea are present, a defendant may escape liability through a valid defence. Self-defence (including defence of property) uses a two-part formula: Self-Defence = Honest Belief of Need + Reasonable Force. The force must be necessary (subjective test, R v Gladstone Williams) and proportionate (objective test, Palmer v The Queen). Excessive force can defeat the defence. Insanity is governed by the M'Naghten Rules: ct of Reason + Caused by Disease of the Mind + Did Not Know Nature/Quality or Wrongfulness. If successful, the verdict is 'not guilty by reason of insanity'. Automatism is a related defence where external factors cause involuntary action (Hill v Baxter).

即便存在犯罪行为和犯罪心理，被告人仍可凭借有效抗辩免于承担责任。自卫（包括防卫财产）采用两阶公式：自卫 = 诚实地相信有必要 + 合理武力。武力须为必要（主观标准，R v Gladstone Williams）且比例相称（客观标准，Palmer v The Queen）。过度武力将使抗辩失效。精神错乱受M'Naghten规则调整：精神错乱 = 理性缺陷 + 由精神疾病引起 + 不知行为性质/质量或错误性。若抗辩成功，裁决为“因精神错乱无罪”。自动化是关联抗辩，由外部因素导致不由自主的行为（Hill v Baxter）。

Full Defence = (Subjective Belief + Objective Proportionality) OR (M'Naghten Defect + Disease + Cognition Failure)

完整抗辩 = （主观信念 + 客观比例性）或 （M'Naghten理性缺陷 + 疾病 + 认知障碍）

8. The Non-Fatal Offences Formula Map | 非致命罪公式地图

Section 47, 20, and 18 offences under the Offences Against the Person Act 1861 build upward from common assault. Use the table to memorise:

《1861年侵害人身罪法》第47、20、18条犯罪从普通恐吓/殴打层层递进。可借助下表记忆：

Offence	Formula	Mens Rea
s.47 ABH	Assault + Occasioning + ABH	Intention or recklessness as to common assault (Savage)
s.20 GBH	Wounding or Inflicting GBH	Intention or recklessness as to some harm (Mowatt)
s.18 GBH with Intent	Wounding or Causing GBH + Ulterior Intent	Specific intent to seriously harm (or resist arrest)

For s.47 the formula is simpler: assault or battery causing ABH, with the mens rea of the underlying common assault. For s.20, inflict grievous bodily harm or wound; recklessness as to some harm suffices. s.18 requires proof of a specific intention to cause serious harm. GBH means 'really serious harm' (DPP v Smith). A wound requires a break in the continuity of the whole skin (Moriarty v Brookes).

第47条的公式更简单：恐吓或殴打导致实际身体伤害，其犯罪心理就是底层普通恐吓/殴打的犯意。第20条需造成重伤或创伤；对产生某些伤害持轻率心态即可。第18条要求证明造成严重伤害的特定故意。重伤意为“真正严重的伤害”（DPP v Smith）。创伤要求皮肤全层的连续性被打破（Moriarty v Brookes）。

s.20 = Malicious Wounding/GBH + MR as to some harm; s.18 = Wounding/GBH + Specific Intent

第47条 = 普通恐吓（行为+犯意）+ 结果（实际身体伤害）；第20条 = 恶意创伤/重伤 + 对某些伤害的犯意；第18条 = 创伤/重伤 + 特定故意

9. The Sentencing and Remedies Theorems | 量刑与救济定理

In criminal law, sentencing factors follow a logical theorem: Sentence = Harm Culpability × Aggravating Factors – Mitigating Factors. Aggravating factors include previous convictions, use of a weapon, vulnerability of the victim. Mitigating factors include age, remorse, early guilty plea. In civil law, remedies are primarily damages, calculated as: Damages = Loss (Pecuniary + Non-Pecuniary) – Contributory Negligence %. Special damages cover quantifiable financial losses up to trial; general damages cover future losses and non-financial harm (pain and suffering). Injunctions are discretionary equitable remedies granted where damages are inadequate. The theorem for contributory negligence reduces damages by the percentage the claimant is at fault (Law Reform (Contributory Negligence) Act 1945, Sayers v Harlow UDC).

刑法中，量刑因素遵循一条逻辑定理：刑罚 = 危害应受遣责性 × 加重因素 – 减轻因素。加重因素包括前科、使用武器、被害人脆弱性。减轻因素包括年龄、悔罪、早期认罪。民事法中，救济主要是损害赔偿，计算公式为：损害赔偿 = 损失（金钱 + 非金钱）– 共同过失百分比。特殊损害赔偿涵盖审前可量化的财务损失；一般损害赔偿涵盖未来损失及非经济损害（疼痛与痛苦）。禁制令是在损害赔偿不充分时裁量授予的衡平法救济。共同过失定理将按索赔人自身过错百分比削减赔偿金额（《1945年法律改革（共同过失）法》，Sayers v Harlow UDC）。

Final Sentence ∝ (Culpability × Harm) + Aggravators – Mitigators; Final Damages = Full Loss – (Loss × Claimant's Fault %)

最终刑罚 ∝ （应受遣责性 × 危害）+ 加重因素 – 减轻因素；最终损害赔偿 = 全部损失 –（损失 × 索赔人过错百分比）

10. The Statutory Interpretation Rules | 制定法解释规则

Judges apply 'formulas' when interpreting statutes. The Literal Rule: Literal Meaning = Ordinary Dictionary Meaning + Parliament's Intention Irrelevant (Whitely v Chappell). The Golden Rule: Golden Meaning = Literal Meaning (unless absurd) → Modified Meaning (R v Allen, Re Sigsworth). The Mischief Rule: Mischief Meaning = Gap in Law + Parliament's Intended Remedy (Smith v Hughes). Purposive approach goes further, asking what Parliament intended to achieve (Pepper v Hart). These interpretative theorems allow the courts to resolve ambiguity, though they often lead to contradictory results depending on the approach adopted.

法官在解释制定法时运用“公式”。字面规则：字面含义 = 普通字典含义 + 议会意图无关（Whitely v Chappell）。黄金规则：黄金含义 = 字面含义（除非荒谬）→ 修正后的含义（R v Allen, Re Sigsworth）。弊端规则：弊端含义 = 法律漏洞 + 议会意图的补救（Smith v Hughes）。目的解释法更进一步，追问议会意欲达成什么目标（Pepper v Hart）。这些解释定理使法院得以解决模糊性，但采取不同方法常导致相互矛盾的结果。

void Absurdity) → (Mischief: Identify Defect + Remedy) → (Purposive: Parliamentary Intent)

解释 = （字面措辞）→ （黄金：避免荒谬）→ （弊端：识别缺陷 + 补救）→ （目的：议会意图）

11. The Doctrine of Precedent Stare Decisis | 遵循先例原则

The hierarchical theorem of case law can be expressed as: g as: Binding Precedent = (Higher Court Decision × Material Facts Identical) → Lower Court Must Follow. For a precedent to bind, the ratio decidendi (the legal reasoning) must be identified and the material facts must be sufficiently similar. Obiter dicta are persuasive but not binding. The Supreme Court (formerly House of Lords) binds all lower courts, though it can depart from its own previous decisions under the 1966 Practice Statement. The Court of Appeal is bound by its own decisions subject to exceptions in Young v Bristol Aeroplane Co Ltd. The High Court binds inferior courts but not itself. This hierarchical formula ensures consistency and predictability in the common law.

判例法的层级定理可表示为：有约束力的先例 = （上级法院判决 × 关键事实相同）→ 下级法院必须遵循。要使先例产生约束力，必须识别判决理由（ratio decidendi），并且关键事实须足够类似。附带意见（obiter dicta）具有说服力但不具约束力。最高法院（原上议院）约束所有下级法院，尽管它可依据1966年实践声明偏离自身先前的判决。上诉法院受自身判决约束，但存在Young v Bristol Aeroplane Co Ltd案所设定的例外。高等法院约束下级法院但不受自身约束。这一层级公式确保了普通法的一致性与可预见性。

Stare Decisis: Ratio Decidendi (Material Facts) × Court Hierarchy = Binding Precedent

遵循先例：判决理由（关键事实） × 法院层级 = 有约束力的先例

12. The Rylands v Fletcher Strict Liability Formula | Rylands v Fletcher严格责任公式

The tort of private nuisance is fault-based, but Rylands v Fletcher (1868) introduces a strict liability formula: ity = Bringing onto Land + Thing Likely to Do Mischief + Escape + Non-Natural Use + Damage. The defendant must accumulate on his land a thing that, if it escapes, is likely to cause damage. There must be an actual escape (Read v J Lyons & Co Ltd). The use of the land must be non-natural, judged at the time (Rickards v Lothian). Defences to Rylands include act of a stranger, default of the claimant, statutory authority, and act of God. If all elements are proved without a defence, the defendant is liable even without proof of fault.

私人妨害侵权以过错为基础，但Rylands v Fletcher（1868）创设了严格责任公式：严格责任 = 带入土地 + 溢出后可能造成损害之物 + 逃逸 + 非自然使用 + 损害。被告须在其土地上积聚一旦逃逸便可能造成损害之物。必须发生实际逃逸（Read v J Lyons & Co Ltd）。土地的使用须为非自然的，应依当时标准判断（Rickards v Lothian）。Rylands规则的抗辩包括：陌生人行为、索赔人自身过失、法定权限和天灾。若所有要件经证明成立且无抗辩事由，被告即便无过错亦须承担责任。

ation + Dangerous Thing + Escape + Non-Natural Use) → Strict Liability, Defences Permitted

Rylands责任 = （积聚 + 危险物 + 逃逸 + 非自然使用）→ 严格责任，允许抗辩
