📚 Year 7 AQA Law: Formula & Theorem Quick-Reference Handbook | Year 7 AQA 法律：公式定理速查手册

Just as scientists use equations to explain the physical world, legal scholars use structured principles – formulas and theorems – to understand rights, duties and justice. This handbook collects the essential legal formulas you will encounter in your Year 7 AQA Law studies. Each ‘formula’ breaks down a rule into its key elements, helping you build a clear mental model of how the law works. Memorising these frameworks will make your analysis faster and more accurate.

就像科学家用方程式解释物理世界一样，法学家用结构化的原则——公式与定理——来理解权利、义务和正义。本手册收集了你在 Year 7 AQA 法律课程中会接触到的核心法律公式。每个“公式”都将一条规则拆解成关键要素，帮助你建立清晰的法律思维模型。记住这些框架会让你的分析更迅速、更准确。

1. Crime Formula: Actus Reus + Mens Rea – Defences | 犯罪公式：犯罪行为 + 犯罪意图 — 抗辩理由

In criminal law, most offences can be expressed as a simple equation. A person is guilty of a crime when they carry out a prohibited act (actus reus) with a guilty mind (mens rea) and have no valid defence.

在刑法中，大多数犯罪都可以用一个简单的等式表示。当一个人实施了被禁止的行为（犯罪行为），同时具有犯罪的意图（犯罪意图），而且没有任何有效抗辩时，他就有罪。

Criminal Liability = Actus Reus + Mens Rea − Defence

Actus reus can be an act, a failure to act (omission) or a state of affairs. Mens rea refers to the mental element, such as intention, recklessness or negligence. If either element is missing, the equation is incomplete and the accused may be acquitted. Common defences include self-defence, insanity and duress.

犯罪行为可以是作为、不作为（疏忽）或某种状态。犯罪意图指的是心理因素，比如故意、轻率或过失。如果其中任何一个要素缺失，等式就不成立，被告人可能会被无罪释放。常见的抗辩理由包括自我防卫、精神错乱和胁迫。

2. Theft Formula: Dishonesty + Appropriation + Property + Intention to Permanently Deprive | 盗窃公式：不诚实 + 占有 + 财产 + 永久剥夺的意图

Theft is defined under the Theft Act 1968. To prove theft, five elements must all be established. The formula helps you check each ingredient methodically.

盗窃的定义依据《1968年盗窃法》。要证明盗窃成立，必须同时满足五个要素。这个公式帮助你系统性地逐一检验。

Theft = Dishonest Appropriation of Property Belonging to Another + Intention of Permanently Depriving

Dishonesty is judged by the standards of ordinary decent people. Appropriation means assuming the rights of the owner, such as taking, using or selling the item. Property includes money, personal belongings and intangible property. The final element is the intention to permanently deprive the owner of it; borrowing without intent to keep is not theft.

不诚实根据普通正直人士的标准判定。占有是指行使所有者的权利，比如拿走、使用或出售物品。财产包括金钱、个人财物和无形财产。最后一个要素是意图永久性地剥夺所有者的财产；只是借用而没有占为己有的意图不构成盗窃。

3. Assault and Battery: Core Building Blocks of Non-Fatal Offences | 袭击与殴打：非致命犯罪的核心构建模块

Assault and battery are two distinct common law offences that often appear together. Each has its own formula. Understanding the difference between them is fundamental.

袭击和殴打是两个不同的普通法犯罪，经常同时出现。它们各自有自己的公式。理解二者的区别是基本功。

Assault = Intentionally or Recklessly Causing Another to Apprehend Immediate Unlawful Force

Battery = Intentionally or Recklessly Applying Unlawful Force to Another

For assault, the victim must expect that force is about to be used; physical contact is not required. For battery, actual touching – even a slight push – completes the offence. The mens rea for both is intention or subjective recklessness.

对于袭击，被害人必须预料到即将遭受暴力；实际身体接触并非必需。对于殴打，实际的触碰——哪怕是轻轻一推——就构成犯罪。两者的犯罪意图都是故意或者主观轻率。

4. Negligence Formula: Duty + Breach + Damage + Causation | 过失侵权公式：义务 + 违反 + 损害 + 因果关系

In the civil tort of negligence, a claimant must prove four elements to win compensation. This formula is the backbone of most accident claims, from road collisions to medical errors.

在民事过失侵权中，索赔人必须证明四个要素才能获得赔偿。这个公式是大多数事故索赔的支柱，从交通事故到医疗事故都适用。

Negligence = Duty of Care + Breach of Duty + Damage + Causation

First, the defendant must owe the claimant a duty of care (neighbour principle from Donoghue v Stevenson). Second, the defendant must have fallen below the standard of care expected of a reasonable person. Third, the claimant must have suffered actual harm or loss. Fourth, the breach must be both factually and legally the cause of the damage.

首先，被告必须对原告负有注意义务（源自 Donoghue v Stevenson 案的邻人原则）。其次，被告的行为必须低于理性人的注意标准。第三，原告必须遭受了实际伤害或损失。第四，这种违反行为必须在事实上和法律上都是损害的原因。

5. Contract Formation: Offer + Acceptance + Consideration + Intention | 合同成立：要约 + 承诺 + 对价 + 意图

A binding contract does not appear out of nowhere; it is constructed from these four pillars. Missing one piece means there is no enforceable agreement.

一份有约束力的合同并非凭空产生；它由这四根支柱构成。缺少任何一项都意味着不存在可强制执行的协议。

Valid Contract = Offer + Acceptance + Consideration + Intention to Create Legal Relations

An offer is a clear statement of willingness to be bound on stated terms. Acceptance must mirror the offer and be communicated. Consideration is something of value exchanged between the parties. Intention is presumed in commercial contexts but must be shown in social and domestic agreements.

要约是明确表示愿意在所述条款上受约束的声明。承诺必须与要约一致并被传达。对价是双方之间的价值交换。意图在商业场合中被推定存在，但在社交和家庭协议中必须加以证明。

6. Contract Terms: Express and Implied Terms | 合同条款：明示与默示条款

Once a contract exists, its content is shaped by terms. This formula distinguishes the sources of those rules.

一旦合同成立，其内容由条款塑造。这个公式区分了这些规则的来源。

Contractual Obligations = Express Terms + Implied Terms

Express terms are those explicitly agreed by the parties, whether spoken or written. Implied terms are inserted by courts or statute to make the contract workable, such as the Sales of Goods Act requirement that goods be of satisfactory quality. Breach of either type can lead to remedies like damages.

明示条款是双方明确同意的内容，无论是口头还是书面。默示条款是由法院或法律植入以使合同可行的内容，比如《货物买卖法》要求货物质量令人满意。违反任何一种条款都可能导致损害赔偿等救济。

7. Tort of Trespass to Land: Direct Entry Without Permission | 土地侵权：未经许可的直接侵入

Trespass to land protects the right to exclusive possession of property. The formula is straightforward but strict.

土地侵权保护了对财产的排他性占有权。公式直接且严格。

Trespass to Land = Direct + Intentional + Interference with Another’s Land + Without Lawful Justification

The interference must be direct, such as walking onto land or throwing objects. It must be voluntary and intentional, though the defendant need not know they are trespassing. The claimant need only prove they have a better right to possession; damage is not required. A lawful excuse, such as a warrant, negates the tort.

这种干扰必须是直接的，比如走入土地或投掷物体。行为必须是自愿和有意的，尽管被告不一定知道自己在侵入。原告只需证明自己有更优的占有权即可；不必证明损害。合法的免责理由，如搜查令，会使侵权不成立。

8. Judicial Precedent: Ratio Decidendi + Obiter Dicta | 司法先例：判决理由 + 附带意见

In the English legal system, precedents create law through judgments. This formula helps you extract the binding and persuasive parts of a case.

在英格兰法律体系中，先例通过判决创造法律。这个公式帮助你从案例中提取具有约束力和说服力的部分。

Precedent = Ratio Decidendi (Binding) + Obiter Dicta (Persuasive)

Ratio decidendi is the legal reason for the decision; it binds lower courts in future similar cases under the doctrine of stare decisis. Obiter dicta are judicial statements made in passing, not essential to the outcome; they are not binding but may influence later cases, especially when delivered by senior judges. Distinguishing cases and overruling are key techniques for avoiding precedent.

判决理由是裁决的法律依据；根据遵循先例原则，它对下级法院将来的类似案件具有约束力。附带意见是法官的附带陈述，对结果无关紧要；它们不具有约束力，但可能影响后来的案件，尤其是由高级法官发表时。区分案例和推翻先例是规避先例的关键技术。

9. Statutory Interpretation Rules: Literal, Golden and Mischief | 制定法解释规则：字面规则、黄金规则和填补损害规则

Judges follow set approaches when interpreting acts of Parliament. This trio of rules can be seen as a decision-making formula for finding Parliament’s true intention.

法官在解释议会立法时遵循一套方法。这三种规则可以看作用于寻找议会真实意图的决策公式。

Interpretation Approach = Literal Rule → (if absurd) Golden Rule → Mischief Rule (Purpose)

The literal rule gives words their ordinary, dictionary meaning. If that leads to an absurd result, the golden rule allows the court to choose an alternative meaning that avoids the absurdity. The mischief rule looks back to the gap in the law that the statute intended to fill, examining the purpose of the legislation. The purposive approach is a modern extension favoured by European and human rights law.

字面规则赋予词语通常的字典含义。如果这导致荒谬的结果，黄金规则允许法院选择另一种含义以避免荒谬。填补损害规则回溯到该法律旨在填补的法律漏洞，审查立法的目的。目的解释法是现代普遍采用的延伸方法，受到欧洲法和人权法的青睐。

10. Defence Formula: Self-Defence = Honest Belief + Reasonable Force | 抗辩公式：自我防卫 = 真诚信念 + 合理武力

Self-defence is a complete defence in both criminal and civil law. This two-part test decides whether a person’s violent response to a threat is lawful.

自我防卫在刑法和民法中都是一项完全的抗辩。这个两步测试决定了一个人对威胁作出的暴力回应是否合法。

Self-Defence = Honest Belief of Threat + Reasonable Degree of Force

The defendant must genuinely believe that force is necessary to defend themselves or another. This belief is judged subjectively. The amount of force used must be objectively reasonable in the circumstances as the defendant believed them to be. Excessive force will break the formula and the defence fails. Intoxication by choice cannot support a mistaken belief.

被告人必须真诚地相信使用武力是为了防卫自己或他人所必要的。这种信念是主观判断的。使用的武力程度必须在被告人所认为的情形下客观上合理。过度的武力会打破这个公式，导致抗辩失败。自愿醉酒不能成为错误信念的依据。

11. Sentencing Goals: Retribution, Deterrence, Rehabilitation, Protection | 量刑目标：报应、威慑、改造、保护

When a court passes sentence, it must balance several purposes. This formula captures the aims of sentencing under section 57 of the Sentencing Act 2020.

当法院宣判刑罚时，必须平衡多个目的。这个公式概括了《2020年量刑法》第57条下的量刑目标。

Sentence Aims = Retribution + Deterrence + Rehabilitation + Public Protection + Reparation

Retribution is the punishment of offenders to reflect society’s disapproval. Deterrence aims to discourage the offender and others from committing crimes. Rehabilitation helps offenders change their behaviour. Protection of the public removes dangerous individuals from society. Reparation encourages offenders to make amends to victims.

报应是指惩罚犯罪人，以反映社会的不赞同。威慑旨在使犯罪人和他人不敢犯罪。改造帮助犯罪人改变行为。保护公众是将危险人物从社会中移除。赔偿鼓励犯罪人对被害人进行弥补。

12. Proportionality in Human Rights: Legitimate Aim + Necessity + Balancing | 人权比例性：合法目的 + 必要 + 平衡

In human rights law, the state may sometimes restrict a right, but only if the interference is proportionate. This formula is used by courts when applying the Human Rights Act 1998.

在人权法中，国家有时可以限制一项权利，但前提是该干预是适度的。法院在适用《1998年人权法》时使用这个公式。

Proportionate Interference = Legitimate Aim + Rational Connection + Necessary + Fair Balance

The measure must pursue a legitimate aim, such as national security or public safety. There must be a rational connection between the measure and that aim. The interference must be no more than necessary to achieve it, and the severity of the restriction must be balanced against the importance of the right. If any stage fails, the interference is unlawful.

该措施必须追求合法的目的，比如国家安全或公共安全。措施与目的之间必须有合理的联系。干预不得超过实现该目的所必需的程度，而且限制的严厉程度必须与权利的重要性相平衡。如果任何阶段不成立，干预就是非法的。
