1. The Nature and Purpose of Law | 法律的性质与目的
Law is a set of rules created by the state to regulate behaviour in society. It is enforceable through sanctions such as fines, imprisonment, or compensation. Unlike moral or social norms, legal rules are binding on all members of a community and are applied by courts in a systematic way.
法律是由国家制定的、用于规范社会行为的一整套规则。它通过罚款、监禁或赔偿等制裁措施加以执行。与道德或社会规范不同，法律规定对全体社会成员具有约束力，并由法院以系统化的方式加以适用。
The main purposes of law include maintaining order, protecting individual rights and freedoms, resolving disputes, and promoting social justice. Without a legal framework, societies would struggle to achieve predictability and fairness.
法律的主要目的包括维护秩序、保护个人权利与自由、解决纠纷以及促进社会正义。缺少法律框架，社会将难以实现可预见性和公平。
- Order and stability: laws deter harmful conduct. / 秩序与稳定：法律对有害行为产生威慑作用。
- Protecting rights: the law shields citizens from abuse of power. / 保护权利：法律防止公民遭受权力滥用之害。
- Dispute resolution: courts provide a neutral forum for settling conflicts. / 解决争议：法院提供中立的争议解决平台。
- Social change: legislation can drive improvements, such as equality acts. / 社会变革：立法能够推动进步，例如平等法案。
2. Sources of Law: Legislation and Precedent | 法律渊源：立法与判例
In the English legal system, law comes from two principal sources: Parliament-made statute law and judge-made common law. Statute law, also known as legislation, is created through Acts of Parliament and takes precedence over other sources. Delegated legislation, such as statutory instruments, is made by bodies given authority by an Act of Parliament.
在英格兰法律体系中，法律有两个主要渊源：议会制定的成文法与法官造的普通法。成文法，即立法，通过议会法案产生，且效力优先于其他渊源。授权立法，如法定文件，由议会法案授予权力的机构制定。
Common law, or case law, develops through the doctrine of precedent (stare decisis). Judges in higher courts set binding principles that lower courts must follow in similar cases. The Supreme Court replaced the House of Lords as the highest court in 2009. Its decisions bind all courts below.
普通法，或称判例法，通过遵循先例的原则发展而来。上级法院的法官确立有约束力的原则，下级法院在类似案件中必须遵循。最高法院于2009年取代上议院成为最高司法机构，其判决对所有下级法院具有约束力。
| Source / 渊源 | Description / 描述 |
| Primary legislation / 初级立法 | Acts of Parliament, supreme law. / 议会法案，最高法律。 |
| Secondary legislation / 授权立法 | Rules made by ministers under an Act. / 部长依据法案制定的规则。 |
| Judicial precedent / 司法先例 | Binding rulings from higher courts. / 上级法院具有约束力的裁决。 |
| European law (retained) / 保留的欧盟法 | Some EU-derived laws still apply post-Brexit. / 部分源自欧盟的法律在脱欧后仍适用。 |
3. The Criminal Justice System | 刑事司法体系
A criminal offence is an act prohibited by the state that carries a punishment. The burden of proof lies on the prosecution, and the standard of proof is ‘beyond reasonable doubt’. The aim of criminal law is to punish wrongdoing, deter crime, rehabilitate offenders, and protect the public.
刑事犯罪是国家禁止并处以刑罚的行为。举证责任在控方，证明标准为”超出合理怀疑”。刑法的目的是惩罚不当行为、威慑犯罪、改造罪犯并保护公众。
Crimes are categorised by seriousness: summary offences (less serious, tried in Magistrates’ Court), indictable offences (serious, heard in Crown Court), and either-way offences (can be tried in either court). The police and Crown Prosecution Service (CPS) investigate and bring charges.
犯罪按严重程度分为：简易罪（较轻，由治安法院审理）、可诉罪（严重，由皇家刑事法院审理）和两可罪（可选择任一法院审理）。警方与皇家检察署负责调查并提出指控。
- Summary: e.g., minor traffic offences. / 简易罪：如轻微交通违法。
- Indictable: e.g., murder, rape. / 可诉罪：如谋杀、强奸。
- Either-way: e.g., theft, burglary. / 两可罪：如盗窃、入室行窃。
4. Principles of Criminal Liability | 刑事责任原则
To establish criminal liability, the prosecution must usually prove both the actus reus (guilty act) and the mens rea (guilty mind). Actus reus can be a positive act, an omission where there is a duty to act, or a state of affairs. Mens rea refers to the mental element, such as intention, recklessness, or gross negligence.
要确立刑事责任，控方通常必须同时证明犯罪行为（actus reus）与犯罪意图（mens rea）。犯罪行为可以是积极行为、负有作为义务下的不作为，以及一种特定状态。犯罪意图指精神要素，如蓄意、轻率或严重疏忽。
Strict liability offences are exceptions: they require only the actus reus, with no need to prove mens rea. Common examples include food hygiene regulations and some driving offences. These are justified by the need to protect public safety.
严格责任犯罪属于例外情况：只需具备犯罪行为，无需证明犯罪意图。常见例子包括食品卫生规定和某些驾驶犯罪，其正当性在于保护公众安全的需要。
5. Key Criminal Offences | 关键刑事罪名
Non-fatal offences against the person include assault (causing fear of immediate violence), battery (unlawful physical contact), actual bodily harm (ABH under s.47 OAPA 1861), and grievous bodily harm (GBH under s.18 and s.20). The level of harm and the defendant’s intention determine the charge.
非致命人身侵害包括恐吓（使他人担心即将遭受暴力）、殴打（非法身体接触）、实际身体伤害（根据1861年《侵害人身罪法》第47条）和严重身体伤害（根据第18条和第20条）。伤害程度与被告意图决定指控。
Property offences cover theft (dishonest appropriation of property belonging to another with intent to permanently deprive), robbery (theft using force or threat of force), and burglary (entering a building as a trespasser with intent to steal, inflict GBH, or cause damage).
财产犯罪包括盗窃（不诚实地将他人的财产据为己有，并具有永久剥夺的意图）、抢劫（使用暴力或暴力威胁实施盗窃）和入室行窃（作为侵入者进入建筑物，意图盗窃、造成严重身体伤害或造成损害）。
| Offence / 罪名 | Actus Reus / 犯罪行为 | Mens Rea / 犯罪意图 |
| Theft / 盗窃 | Appropriation of property / 占有财产 | Dishonesty, intent to deprive / 不诚实、意图剥夺 |
| Robbery / 抢劫 | Theft + force/threat / 盗窃+暴力/威胁 | Mens rea of theft + intent to use force / 盗窃意图+使用暴力意图 |
| Burglary s.9(1) / 入室行窃 9(1) | Entry as trespasser / 侵入者进入 | Intent to steal, inflict GBH, or damage / 意图盗窃、造成严重伤害或损坏 |
6. Defences in Criminal Law | 刑事辩护理由
Even when the elements of an offence are present, a defendant may raise a full or partial defence. Self-defence is a full defence if the force used was reasonable and necessary. The defendant’s belief in the need for force is judged subjectively, but the reasonableness of the force is assessed objectively.
即便犯罪构成要件成立，被告仍可提出完全或部分辩护理由。自卫是一种完全辩护，条件为使用的武力是合理且必要的。被告是否相信自己需要采取武力属主观判断，但武力是否合理则进行客观评估。
Duress (threats forcing the defendant to commit a crime) is not available for murder or attempted murder. Intoxication may negate mens rea for crimes of specific intent if it was involuntary, but voluntary intoxication rarely provides an excuse. Insanity and automatism are defences based on the defendant’s mental state or lack of control.
被胁迫抗辩不适用于谋杀或谋杀未遂。非自愿醉酒可能否定特定意图犯罪的犯罪意图，但自愿醉酒极少构成免责理由。精神错乱和自动症是基于被告精神状态或缺乏控制能力的辩护。
- Self-defence: reasonable, necessary force. / 自卫：合理、必要的武力。
- Duress: threat of death or serious injury. / 被胁迫：以死亡或严重伤害相威胁。
- Insanity: defect of reason from disease of the mind. / 精神错乱：因精神疾病导致理性缺陷。
- Automatism: external factor causes involuntary act. / 自动症：外部因素导致的不自主行为。
7. Tort Law: The Duty of Care | 侵权法：注意义务
Tort law deals with civil wrongs that cause harm or loss to another. The most common tort is negligence, which requires the claimant to prove that the defendant owed them a duty of care, breached that duty, and caused foreseeable damage. The ‘neighbour principle’ from Donoghue v Stevenson established that we must take reasonable care to avoid acts that could foreseeably injure others.
侵权法处理对他人造成伤害或损失的民事过错。最常见的侵权行为是过失侵权，原告须证明被告对其负有注意义务、违反了该义务并造成了可预见的损害。Donoghue v Stevenson 案确立的”邻人原则”指出，我们必须尽合理注意，避免可预见会伤害他人的行为。
The Caparo three-part test refines the duty of care: foreseeability of harm, proximity between the parties, and whether it is fair, just and reasonable to impose a duty. Breach occurs when the defendant fails to meet the standard of a reasonable person, and causation is proved using the ‘but for’ test and the concept of remoteness of damage.
Caparo 三阶段检验法细化了注意义务：损害的可预见性、双方当事人之间的密切关系，以及施加义务是否公平、公正且合理。当被告未能达到合理人的标准时即构成违反义务，因果关系通过”若非”检验和损害的隔远性概念加以证明。
8. Contract Law: Formation and Breach | 合同法：合同的成立与违约
A legally binding contract requires an offer, acceptance, consideration, and an intention to create legal relations. An offer is a clear statement of terms on which the offeror is willing to be bound. Invitations to treat, such as goods on a shelf, are not offers but invitations to negotiate.
一份具有法律约束力的合同需要具备要约、承诺、对价和建立法律关系的意图。要约是对条款的明确陈述，表明要约人愿意受其约束。要约邀请，如货架上的商品，不是要约而是邀请谈判。
Acceptance must be communicated and mirror the terms of the offer. Consideration is the price paid for the promise, though it need not be adequate. Breach of contract occurs when a party fails to perform their obligations, entitling the innocent party to remedies such as damages, specific performance, or injunction.
承诺必须通知对方且与要约条款一致。对价是为换取允诺而付出的代价，但无须对等。当一方未能履行其义务时即构成违约，无辜方有权获得损害赔偿、特定履行或禁制令等救济。
| Element / 要素 | Key rule / 关键规则 |
| Offer / 要约 | Distinguished from invitation to treat e.g., Pharmaceutical Society v Boots. / 区别于要约邀请，如 Pharmaceutical Society v Boots 案。 |
| Acceptance / 承诺 | Must be communicated; silence is not acceptance (Felthouse v Bindley). / 必须通知；沉默不构成承诺（Felthouse v Bindley 案）。 |
| Consideration / 对价 | Must move from promisee, need not be adequate (Thomas v Thomas). / 须由受诺人提供，无须对等（Thomas v Thomas 案）。 |
9. Human Rights and the Law | 人权与法律
The Human Rights Act 1998 incorporated the European Convention on Human Rights into UK law. It obliges public authorities to act compatibly with Convention rights, including the right to life (Article 2), freedom from torture (Article 3), the right to a fair trial (Article 6), and respect for private and family life (Article 8).
1998年《人权法令》将《欧洲人权公约》纳入英国法律。该法要求公共机构以符合公约权利的方式行事，这些权利包括生命权（第2条）、免受酷刑（第3条）、获得公正审判的权利（第6条）以及尊重私人和家庭生活的权利（第8条）。
Courts cannot strike down primary legislation that conflicts with Convention rights, but they can issue a declaration of incompatibility under s.4. This places political pressure on Parliament to amend the law. Rights are qualified, meaning they can be limited to protect national security, public safety, or the rights of others, provided the restriction is proportionate.
法院不能推翻与公约权利相冲突的初级立法，但可根据第4条发出不一致宣告，从而对议会施加修改法律的政治压力。权利是有限制的，即可为保护国家安全、公共安全或他人权利而加以限制，但此类限制必须符合比例原则。
- Absolute rights: e.g., Article 3, never limited. / 绝对权利：如第3条，不可限制。
- Limited rights: e.g., Article 5, limited in defined circumstances. / 有限权利：如第5条，在特定情况下可被限制。
- Qualified rights: e.g., Articles 8-11, balanced against public interest. / 受限权利：如第8–11条，须与公共利益平衡。
10. The Courts and Legal Personnel | 法院与法律人员
The court structure in England and Wales separates criminal and civil matters. Magistrates’ Courts try summary offences and commit serious cases to the Crown Court. The Crown Court deals with indictable offences and appeals from Magistrates. In civil cases, the County Court handles small claims and fast-track matters, while the High Court deals with complex cases.
英格兰和威尔士的法院架构将刑事与民事案件分开。治安法院审理简易罪，并将严重案件移送刑事法院。刑事法院处理可诉罪及治安法院的上诉。在民事案件中，郡法院负责小额索赔和快速审理案件，高等法院则处理复杂案件。
Legal professionals include solicitors, who provide initial advice and instruct barristers; barristers, who specialise in advocacy in higher courts; and judges, who preside over proceedings. Lay people also play a vital role: magistrates hear most criminal cases without legal qualifications, while juries decide guilt in serious Crown Court trials.
法律专业人士包括提供初步咨询并指示出庭律师的事务律师；专长于在更高级法院进行辩护的出庭律师；以及主持诉讼程序的法官。非法律专业人士也发挥着关键作用：治安法官在不要求法律资格的情况下审理大多数刑事案件，而陪审团则在严重的刑事法院审判中决定是否有罪。
An independent judiciary and the separation of powers ensure that judges can apply the law without political interference. Judicial appointments are made by the Judicial Appointments Commission, based on merit.
独立的司法机构和权力分立确保法官能够不受政治干预地适用法律。司法任命由司法任命委员会根据能力进行。
