📚 Year 11 Eduqas Law: Quick Reference Guide to Legal Formulas and Principles | 法律公式定理速查手册
Law may not contain mathematical equations, but it is built upon precise legal 'formulas' that determine guilt, liability and rights. This quick reference guide translates the core principles of the Year 11 Eduqas Law specification into memorable rule‑based statements, helping you master criminal law, tort and contract through the logic of legal formulas.
法律也许没有数学方程式，但它建立在精确的法律“公式”之上，这些公式决定了罪责、责任与权利。这份速查手册将 Year 11 Eduqas 法律课程的核心原则转化为便于记忆的规则性陈述，帮助你通过法律公式的逻辑掌握刑法、侵权法和合同法。
1. The Criminal Liability Formula | 刑事责任公式
The foundation of almost every criminal offence can be expressed as: Actus Reus (guilty act) + Mens Rea (guilty mind) – any valid defence = Criminal Liability. Both elements must be present at the same time for a conviction.
几乎所有刑事犯罪的基础都可以表示为：犯罪行为 + 犯罪意图 – 任何有效辩护理由 = 刑事责任。两者必须同时存在才能定罪。
This formula applies to the majority of offences under English law. For instance, in theft the actus reus is the appropriation of property belonging to another, and the mens rea is dishonesty with the intention to permanently deprive.
这一公式适用于英格兰法律中的大多数犯罪。例如，在盗窃罪中，犯罪行为是挪用他人财产，犯罪意图是不诚实地意图永久剥夺。
2. Breaking Down Actus Reus | 犯罪行为分解公式
Actus reus can be an act, an omission or a state of affairs. The standard formula is: tary conduct (or recognised omission) + causation of a prohibited consequence = Actus Reus. Omissions only count where a legal duty exists.
犯罪行为可以是一种作为、不作为或状态。标准公式为：自愿行为（或法院认可的不作为）+ 造成法律禁止的后果 = 犯罪行为。不作为仅在存在法律义务时才构成犯罪行为。
Legal duties arise from statute (e.g. duty to stop at a red light), contract (Pittwood), a special relationship (parent and child, Gibbins & Proctor), voluntary assumption of care (Stone & Dobinson), or creation of a dangerous situation (Miller).
法律义务源于成文法（如红灯停车义务）、合同（Pittwood 案）、特殊关系（父母与子女，Gibbins & Proctor 案）、自愿承担照护责任（Stone & Dobinson 案）或制造危险情形（Miller 案）。
3. Types of Mens Rea | 犯罪意图类型公式
The hierarchy of mens rea can be ordered from highest to lowest culpability: Intention (direct or oblique) → Recklessness → Negligence. Some offences require specific intent, while others can be satisfied by recklessness.
犯罪意图的层级可按可责难性从高到低排列：意图（直接或间接）→ 轻率（鲁莽）→ 过失。某些犯罪要求特定意图，而其他犯罪可通过轻率满足。
Direct intention means it was the defendant's aim or purpose to bring about the consequence (Mohan). Oblique intention applies when the consequence was a virtual certainty and the defendant appreciated that (Woollin). Recklessness is taking an unjustified risk that a reasonable person would not take.
直接意图指后果是被告的目的或目标（Mohan 案）。间接意图适用于后果是几乎确然发生且被告认识到这一点的情形（Woollin 案）。轻率是指承担了一个有理性的普通人不会承担的、不合理风险。
4. The Causation Formula | 因果关系公式
To establish actus reus in result crimes, the prosecution must prove: Factual causation (the 'but for' test) + Legal causation (substantial and operative cause) = Causation. Both must be satisfied.
在结果犯中确立犯罪行为，控方必须证明：事实因果关系（“若无则不”检验）+ 法律因果关系（实质且有效的致因）= 因果关系。两者都必须满足。
Factual causation uses the 'but for' test: but for the defendant's conduct, would the result have occurred? (White). Legal causation requires that the defendant's act was a substantial and operative cause of the harm, more than a minimal contribution (Smith).
事实因果关系采用“若无则不”检验：若无被告的行为，该结果是否会发生？（White 案）。法律因果关系要求被告的行为是损害的一个实质且有效的致因，超出微小贡献（Smith 案）。
Intervening acts may break the chain of causation if they are free, deliberate and informed (voluntary acts of the victim or third parties) or abnormal natural events. However, medical negligence very rarely breaks the chain (Cheshire).
介入行为如果是自由、自愿且知情的（被害人或第三方的自愿行为）或异常自然事件，可能中断因果关系链。然而，医疗过失极少中断因果关系链（Cheshire 案）。
5. Strict Liability Offences | 严格责任定理
Strict liability simplifies the criminal formula to: Actus Reus alone (no need to prove mens rea for at least one element) = Liability. This means the defendant can be convicted even if they had no blameworthy mind.
严格责任将刑事责任公式简化为：仅有犯罪行为（对于至少一个要素无需证明犯罪意图）= 责任。这意味着即使被告没有可责难的心态也可能被定罪。
Common strict liability offences include regulatory crimes such as selling alcohol to underage persons, food safety breaches and driving over the speed limit. Even due diligence is not always a defence unless provided by statute.
常见的严格责任犯罪包括监管类犯罪，如向未成年人售酒、违反食品安全规定和超速驾驶。即使是尽到应尽努力也并非总能作为辩护理由，除非成文法有明确规定。
6. Non‑Fatal Offences Against the Person | 人身非致命犯罪公式
The hierarchy of non‑fatal offences can be structured as increasing degrees of harm and intent: force) → ABH (actual bodily harm) → GBH (grievous bodily harm) with intent or recklessness.
人身非致命犯罪的层级可根据伤害程度和意图程度的增加来构建：恐吓（使他人担心立即遭受武力）→ 殴击（施加非法武力）→ 导致实际身体伤害的殴击 → 蓄意或轻率造成严重身体伤害。
Assault and battery are defined under common law and are charged under s.39 Criminal Justice Act 1988. Assault requires causing the victim to apprehend imminent unlawful force (Lamb). Battery requires the intentional or reckless application of unlawful force (Collins v Wilcock).
恐吓和殴击由普通法界定，根据《1988 年刑事司法法令》第 39 条起诉。恐吓要求造成被害人担心即将遭受非法武力（Lamb 案）。殴击要求故意或轻率地施加非法武力（Collins v Wilcock 案）。
Section 47 ABH requires assault or battery that occasions (causes) actual bodily harm, defined as hurt or damage that is more than transient (Miller). Section 18 and 20 GBH involve serious harm, with s.18 requiring specific intent to cause grievous bodily harm or resist arrest.
第 47 条的实际身体伤害要求有造成实际身体伤害的恐吓或殴击，该伤害被界定为超过短暂程度的创伤或损害（Miller 案）。第 18 条和第 20 条的严重身体伤害涉及严重伤害，其中第 18 条要求具有造成严重身体伤害或拒捕的特定意图。
7. Property Offences: The Theft Formula | 财产犯罪：盗窃公式
Theft under s.1 Theft Act 1968 can be broken down as: propriation of property belonging to another with intention to permanently deprive = Theft. All five elements must be proven simultaneously.
根据《1968 年盗窃法》第 1 条，盗窃可以分解为：不诚实地挪用他人财产，意图永久剥夺 = 盗窃。全部五个要素必须同时被证明。
'Dishonesty' is tested through s.2 and the Ivey test: was what the defendant did dishonest according to the standards of ordinary decent people, and did the defendant appreciate that? Sections 3-6 define appropriation, property, belonging to another and intention to permanently deprive.
“不诚实”通过第 2 条和 Ivey 检验确定：被告的行为根据普通正直人士的标准是否不诚实，以及被告是否意识到这一点？第 3 至 6 条界定了挪用、财产、属于他人和意图永久剥夺。
8. The Tort of Negligence Formula | 过失侵权公式
In the law of tort, the negligence formula is: + Breach of that duty + Damage caused by the breach (causation) = Liability in Negligence. The claimant must also prove the damage is not too remote.
在侵权法中，过失侵权公式为：注意义务 + 违反该义务 + 因违反义务造成的损害（因果关系）= 过失侵权责任。原告还必须证明损害并非过远。
A duty of care owes to a neighbour – those closely and directly affected by the defendant's acts (Donoghue v Stevenson). Breach of duty occurs when the defendant falls below the standard of the reasonable person (Blyth v Birmingham Waterworks). The risk factors from the case of Bolton v Stone help determine breach.
注意义务存在于对邻人——即那些密切且直接受到被告行为影响的人（Donoghue v Stevenson 案）。当被告的行为低于理性人标准时即构成义务违反（Blyth v Birmingham Waterworks 案）。Bolton v Stone 案中的风险因素有助于判断是否违反义务。
9. The Tort of Private Nuisance | 私人妨害侵权公式
Private nuisance can be expressed as: Unlawful interference with another's use or enjoyment of land + unreasonableness = Liability in Private Nuisance. It is a tort that protects interests in land.
私人妨害可以表示为：非法干涉他人对土地的使用或享用 + 不合理性 = 私人妨害侵权责任。这是一个保护土地权益的侵权类型。
The court considers factors such as the character of the neighbourhood (Sturges v Bridgman), duration, sensitivity of the claimant and malice. An act that is reasonable in one area may be a nuisance in another. The damage must be reasonably foreseeable.
法院考量社区特征（Sturges v Bridgman 案）、持续时间、原告的敏感程度和恶意等因素。在某一区域合理的行为在另一区域可能构成妨害。损害必须是合理可预见的。
10. Contract Formation Essentials | 合同成立要素公式
A legally binding contract forms through: ceptance + Consideration + Intention to create legal relations + Capacity = Valid Contract. Missing any one element usually prevents formation.
一份具有法律约束力的合同通过以下要素成立：要约 + 承诺 + 对价 + 创立法律关系的意图 + 行为能力 = 有效合同。缺少任一要素通常阻止合同成立。
An offer must be clear (Gibson v Manchester City Council), and acceptance must be communicated and unconditional. The postal rule states acceptance by post takes effect when the letter is posted (Adams v Lindsell). Consideration is something of value exchanged between the parties, though it need not be adequate.
要约必须明确（Gibson v Manchester City Council 案），承诺必须传达且无条件。邮寄规则规定以信件作出的承诺在投邮时生效（Adams v Lindsell 案）。对价是双方之间交换的有价值之物，但不必足够充分。
11. The Hierarchy of Legal Sources | 法律渊源层级定理
The legal system operates under a doctrinal formula: Statute law (Parliamentary sovereignty) prevails over all other sources of law. Where statute and common law conflict, statute wins. Judicial precedent is binding under the practice of stare decisis but can be overridden by legislation.
法律体系依据一项教义性定理运行：成文法（议会主权）优于所有其他法律渊源。当成文法与普通法冲突时，成文法优先。司法先例在遵循先例原则下具有约束力，但可以被立法推翻。
The Human Rights Act 1998 requires courts to interpret legislation compatibly with the European Convention on Human Rights, adding a layer of rights‑based scrutiny to all laws. Delegated legislation, although created by ministers, must stay within the parent Act's scope.
《1998 年人权法》要求法院以符合《欧洲人权公约》的方式解释立法，为所有法律增加了基于权利的审查。委任立法虽由部长制定，但必须在其母法范围内。
12. The Rules of Statutory Interpretation | 法律解释规则定理
When interpreting statutes, judges use four main 'rules' that act as interpretive formulas: ok at the gap the Act intended to fill) → Purposive approach (interpret to achieve the Act's purpose).
在解释成文法时，法官运用四个主要的“规则”作为解释公式：字面规则（按通常含义）→ 黄金规则（为避免荒谬结果而修改含义）→ 缺陷规则（探究该法所欲填补的法律漏洞）→ 目的解释方法（为实现该法的目的而解释）。
The literal rule was applied in Whitely v Chappell, where the defendant was acquitted because a dead person was not 'entitled to vote'. The golden rule altered the literal meaning in Adler v George to avoid an absurdity. The mischief rule was famously used in Smith v Hughes to extend the Misrepresentation Act's protection.
字面规则在 Whitely v Chappell 案中得到适用，被告因死者不属于“有权投票之人”而被判无罪。黄金规则在 Adler v George 案中修改了字面含义以避免荒谬结果。缺陷规则在 Smith v Hughes 案中被用于扩大《虚假陈述法》的保护范围。
