欢迎阅读 Year 10 剑桥 IGCSE 法律核心复习指南。本文凝练了从法律规则的性质、英国法的渊源到刑法、侵权法和合同法基础等核心主题。理解这些构建模块对于考试成功以及加深对法律在社会中如何运作的认识至关重要。
1. The Nature of Law | 法律的性质
Law can be defined as a set of rules created by the state that are enforceable through the courts. These rules are backed by sanctions, such as fines, imprisonment or compensation orders, which distinguish legal rules from social rules and moral norms. Social rules, like queuing or table manners, are not enforceable by the state, whereas a breach of a legal rule leads to state-imposed consequences.
法律可以被定义为一套由国家制定、可通过法院强制执行的规则。这些规则以制裁（如罚款、监禁或赔偿令）为后盾，这使得法律规则区别于社会规则和道德规范。社会规则（如排队或餐桌礼仪）不由国家强制执行，而违反法律规则则会导致国家施加的后果。
Law and morality often overlap but are not identical. Some laws are based on widely held moral values, such as the prohibition of murder, but other laws (e.g. parking regulations) are morally neutral. Justice, in a legal sense, is the aim of achieving fair treatment and a proportionate response to wrongdoing. Theories of justice include corrective justice, which focuses on restoring balance, and distributive justice, which concerns the fair allocation of resources.
法律与道德常有交叉但并不等同。有些法律基于广泛持有的道德价值观，例如禁止谋杀，但其他法律（如停车规定）在道德上是中性的。从法律意义上讲，正义是追求公正对待和相称地应对不法行为的目标。正义理论包括矫正正义（侧重于恢复平衡）和分配正义（涉及资源的公平分配）。
2. Sources of Law | 法律的渊源
Statute law, or legislation, is the most important source of law today. It is made by Parliament, which consists of the House of Commons, the House of Lords and the Monarch. Acts of Parliament are supreme and can override any other source. For example, the Offences Against the Person Act 1861 is a key statute in criminal law.
成文法（或称制定法）是当今最重要的法律渊源。它由议会制定，议会的构成包括下议院、上议院和君主。议会立法具有最高效力，可推翻任何其他渊源。例如，《1861 年侵害人身罪法》是刑法中的一部关键成文法。
Common law, also known as case law or judge-made law, is law developed by judges through the decisions of courts. The doctrine of judicial precedent (stare decisis) ensures consistency: courts must follow the rulings of higher courts in similar cases. Common law originated from the customs applied by royal judges after the Norman Conquest and remains a vital source in areas like contract and tort.
普通法（也称判例法或法官造法）是法官通过法院判决发展出的法律。遵循先例原则（stare decisis）确保了一致性：法院必须遵循上级法院在类似案件中的裁决。普通法起源于诺曼征服后王室法官适用的习惯，至今在合同、侵权等领域仍是一个重要渊源。
Equity developed historically to mitigate the rigidity of common law. It creates remedies such as injunctions and specific performance, which are discretionary and only available where common law damages are inadequate. Delegated legislation, made by bodies to which Parliament has delegated power (e.g. government ministers, local authorities), allows detailed rules to be created efficiently, though it is subject to judicial review.
衡平法的发展是为了缓解普通法的僵化。它创设了诸如禁制令和强制履行等补救措施，这些补救是自由裁量的，仅在普通法损害赔偿不足时才能适用。授权立法则由议会授予权力的机构（例如政府大臣、地方当局）制定，可高效创建细则，但须接受司法审查。
3. The Court System | 法院体系
The English legal system distinguishes between criminal courts and civil courts. Criminal courts deal with offences against the state. Magistrates’ Court tries summary offences (e.g. minor assaults, driving offences) and some either-way offences, with appeals going to the Crown Court. The Crown Court hears serious indictable offences (e.g. murder, rape) before a judge and jury. Appeals from the Crown Court go to the Court of Appeal (Criminal Division).
英国法律体系区分刑事法院和民事法院。刑事法院审理针对国家的犯罪。治安法院审理简易罪（如轻微攻击、交通违法）和一些两可罪，上诉向刑事法院提出。刑事法院在法官和陪审团面前审理严重可起诉罪（如谋杀、强奸）。对刑事法院的判决可向（刑事分庭的）上诉法院上诉。
Civil courts resolve disputes between individuals or organisations. The County Court handles small claims and simple civil cases. The High Court has three divisions: Queen’s Bench Division (contract, tort), Chancery Division (equity, trusts, company law) and Family Division. Appeals typically go to the Court of Appeal (Civil Division) and ultimately to the Supreme Court, which is the final court of appeal for all UK cases.
民事法院解决个人或组织之间的纠纷。郡法院处理小额索赔和简单民事案件。高等法院分三个分庭：王座分庭（合同、侵权）、大法官分庭（衡平、信托、公司法）和家事分庭。上诉通常向（民事分庭的）上诉法院提出，最终可上诉至最高法院，后者是英国所有案件的终审法院。
4. Legal Personnel | 法律从业人员
Judges preside over courts and tribunals, ensuring the law is applied fairly. Superior judges include the Justices of the Supreme Court, Lord Justices of Appeal and High Court judges. Inferior judges include circuit judges (Crown and County Court), district judges and magistrates. Judicial independence and security of tenure are essential constitutional safeguards.
法官主持法院和法庭，确保法律得到公正适用。高级法官包括最高法院大法官、上诉法院上诉庭大法官和高等法院法官。下级法官包括巡回法官（刑事法院和郡法院）、地区法官和治安法官。司法独立和职位保障是重要的宪法保障。
Juries are used in less than 1% of criminal trials but are central to serious cases in the Crown Court. The jury of 12 randomly selected individuals decides questions of fact and returns a verdict of guilty or not guilty. In civil cases, juries are rare. Magistrates are unpaid lay members of the community who sit in the Magistrates’ Court, advised on law by a legal adviser. Solicitors provide initial advice and can represent clients in lower courts, while barristers are specialist advocates who present cases in higher courts.
陪审团只在不足1%的刑事审判中使用，但在刑事法院的重大案件中处于核心地位。由12名随机挑选的个人组成的陪审团决定事实问题，并作出有罪或无罪的裁决。在民事案件中，陪审团非常罕见。治安法官是无薪的社区非专业成员，在治安法院审理案件，由法律顾问提供法律建议。事务律师提供初步咨询，可在下级法院代理客户；出庭律师则是专业讼辩律师，在更高级别的法院出庭陈述。
5. Criminal Law: General Principles | 刑法：基本原则
To establish a criminal offence, the prosecution must usually prove both the actus reus (guilty act) and the mens rea (guilty mind). Actus reus includes all elements of the crime other than the defendant’s state of mind, such as conduct, circumstances and consequences. It must be voluntary; an act done while sleepwalking or under a reflex is not an actus reus.
要证明一项刑事犯罪，检方通常必须证明犯罪行为（actus reus）和犯罪意图（mens rea）两者。犯罪行为包括除被告心理状态以外的所有犯罪要素，如行为、情节和后果。它必须是自愿的；在梦游或反射作用下实施的行为不构成犯罪行为。
Mens rea is the mental element. The main types are intention (direct and oblique), recklessness (knowing there is a risk and taking it unjustifiably) and, for some crimes, negligence or knowledge. Strict liability offences require no mens rea for at least one element; they are typically regulatory offences where protecting the public is paramount, such as selling food beyond its use-by date.
犯罪意图属于心理要素。主要类型包括故意（直接故意和间接故意）、轻率（明知有风险而不合理地甘冒风险）以及对某些犯罪而言的疏忽或明知。严格责任犯罪至少有一个要素不要求犯罪意图；这类犯罪通常是保护公众至上的监管性犯罪，例如出售超出保质期的食品。
Causation links the defendant’s conduct to the result. In consequence crimes (e.g. murder, ABH), the prosecution must establish factual causation (the ‘but for’ test) and legal causation, where the defendant’s act must be a substantial and operating cause of the harm, and there must be no intervening act (novus actus interveniens) that breaks the chain of causation.
因果关系将被告的行为与结果连接起来。在结果犯（如谋杀、实际身体伤害）中，检方必须确立事实因果关系（“若无则不”检验标准）和法律因果关系，即被告的行为必须是伤害的实质性和起作用的成因，且不得有中断因果链的介入行为（novus actus interveniens）。
6. Non-fatal Offences against the Person | 非致命人身犯罪
The main non-fatal offences are assault, battery, assault occasioning actual bodily harm (ABH), malicious wounding or inflicting grievous bodily harm (GBH under s.20) and wounding or causing GBH with intent (s.18 OAPA 1861). Assault is any act that causes the victim to apprehend immediate unlawful personal violence; no touching is required. Battery is the actual application of unlawful force on another person.
主要的非致命犯罪包括：企图伤害、殴击、企图伤害致实际身体伤害（ABH）、恶意伤人致重伤（第20条重伤罪）以及意图重伤伤人（第18条《1861年侵害人身罪法》重伤罪）。企图伤害是指任何使受害人担心即将遭受非法人身暴力的行为；无需接触。殴击则是实际对他人施加非法武力。
ABH (s.47) requires assault or battery that causes actual bodily harm, meaning any hurt or injury calculated to interfere with the health or comfort of the victim, such as cuts, bruises or psychiatric harm. The mens rea for s.47 is the same as for the original assault or battery. GBH under s.20 requires a wound (breaking of both layers of the skin) or really serious bodily harm; the mens rea is ‘malice’, meaning intention or recklessness as to some harm. The more serious s.18 requires proof of intent to cause GBH or to resist lawful arrest; it carries a maximum of life imprisonment.
第47条实际身体伤害罪要求企图伤害或殴击行为造成了实际身体伤害，意指任何旨在干扰受害人健康或舒适程度的伤痛或伤害，如割伤、淤伤或精神损害。第47条的犯罪意图与原企图伤害或殴击的意图相同。第20条重伤罪要求造成伤口（皮肤两层破裂）或真正严重的身体伤害；犯罪意图为“恶意”，即对造成某种伤害具有故意或轻率。更严重的第18条要求证明具有造成重伤或抗拒合法逮捕的意图；最高可判终身监禁。
7. Criminal Defences | 刑事辩护
Self-defence is a complete defence if the defendant used force that was genuinely believed to be necessary and the degree of force was reasonable in the circumstances. The law recognises that a person in danger cannot weigh the exact measure of force. Intoxication can be a defence to crimes of specific intent (e.g. s.18 GBH) if the intoxication was involuntary. Voluntary intoxication is no defence unless it negates the mens rea for a specific intent crime; it does not assist where the intoxication itself provides the recklessness (e.g. in s.20 GBH).
如果被告真诚地相信使用武力是必要的，且在当时情况下武力程度是合理的，自卫是一项完全的辩护理由。法律承认身处危险中的人无法精准地权衡武力分寸。醉酒对于特定故意犯罪（如第18条重伤罪），若属非自愿醉酒可成为辩护理由。自愿醉酒不能作为辩护理由，除非它否定了特定故意犯罪的犯罪意图；若醉酒本身已构成轻率（如第20条重伤罪），则无助于辩护。
Consent may be a defence to minor offences like battery in sports or surgery, provided the consent is informed and the act falls within the boundaries of public policy. Duress arises when the defendant is forced to commit a crime under threat of death or serious violence. It is not available for murder or certain treason offences. Automatism negates the actus reus and is a complete defence if the defendant’s act was involuntary due to an external factor, such as being hit by a stone.
同意可能成为对体育或外科手术中轻微殴击等犯罪的辩护理由，前提是同意是知情的且行为未超出公共政策的边界。胁迫指被告在死亡或严重暴力的威胁下被迫犯罪。该辩护不适用于谋杀或某些叛国罪。自动症否定了犯罪行为，若被告的行为因外部因素（如被石头击中）而非自愿，则是一项完全的辩护理由。
8. Tort Law: Negligence | 侵权法：过失
The tort of negligence imposes a duty not to cause foreseeable harm to others. To succeed in a negligence claim, the claimant must prove three elements: the defendant owed a duty of care, the defendant breached that duty, and the breach caused damage that is not too remote.
过失侵权行为规定了不对他人造成可预见损害的义务。要成功主张过失索赔，原告须证明三个要素：被告负有注意义务、被告违反了该义务，且该违反应行为导致了并非过于遥远的损害。
The existence of a duty of care is assessed using the Caparo test (from Caparo Industries plc v Dickman): (1) harm was reasonably foreseeable, (2) there was sufficient proximity between the parties, and (3) it is fair, just and reasonable to impose a duty. The classic example is the neighbour principle from Donoghue v Stevenson, where the manufacturer owed a duty to the consumer. Breach is judged by the standard of the reasonable person, with special standards for professionals and children.
注意义务的存在与否使用 Caparo 测试（源于 Caparo Industries plc v Dickman 案）加以评估：（1）损害是合理可预见的，（2）当事人之间存在足够的近邻关系，（3）施加注意义务是公平、公正且合理的。经典实例是 Donoghue v Stevenson 案中的邻人原则，该案中制造商对消费者负有义务。违反义务按合理人的标准评判，专业人员和儿童有特殊标准。
Causation in negligence follows the ‘but for’ test, and the damage must not be too remote; the rule from The Wagon Mound states that only damage of a kind that was reasonably foreseeable is recoverable. The claimant must also prove that damage was suffered, such as personal injury, property damage or psychiatric harm (with additional control mechanisms for psychiatric injury).
过失中的因果关系遵循“若无则不”检验标准，且损害不可过于遥远；源于 The Wagon Mound 案的规则指出，只有合理可预见类型的损害才可获赔偿。原告还必须证明已遭受损害，例如人身伤害、财产损害或精神损害（精神伤害有额外的控制机制）。
9. Other Torts | 其他侵权行为
Occupiers’ liability concerns the duty owed by those who control premises to entrants who are injured due to the state of the premises. Under the Occupiers’ Liability Act 1957, a common duty of care is owed to lawful visitors: to see that the visitor is reasonably safe in using the premises for the permitted purpose. Under the Occupiers’ Liability Act 1984, a limited duty is owed even to trespassers if the occupier is aware of a danger and the risk is one they may reasonably protect against.
占有人责任涉及场所控制者对该场所状况造成的伤害向进入者所负的义务。根据《1957年占有人责任法》，对合法访问者负有一般注意义务：需确保访问者在以允许的目的使用该场所时是合理安全的。根据《1984年占有人责任法》，若占有人知晓危险且该风险是其可能被合理期待应予防范的，即使对侵入者也负有限度的责任。
Private nuisance is an unlawful interference with a person’s use or enjoyment of land. It typically involves noise, smells, smoke or vibrations. The court balances the competing interests of neighbours, considering factors such as the locality (a rural area tolerates more farming smells), duration and sensitivity of the claimant. An actionable nuisance must be substantial and unreasonable. The main remedy is damages or an injunction.
私人妨扰是对个人使用或享用土地的非非法干涉。通常涉及噪音、气味、烟雾或振动。法院平衡邻里的相互竞争利益，考虑的因素包括地域性（农村地区对农业气味容忍度更高）、持续时间和原告的敏感性等。可起诉的妨扰必须是实质性且不合理的。主要救济是损害赔偿或禁制令。
10. Contract Formation | 合同成立
A valid contract requires offer, acceptance, consideration, intention to create legal relations and capacity. An offer is a definite promise to be bound on specific terms, which is distinguished from an invitation to treat (e.g. goods on a shelf are not offers but invitations for customers to make an offer: Pharmaceutical Society v Boots). Acceptance must be an unconditional agreement to all the terms of the offer and must be communicated; the postal rule is an exception, where acceptance by post takes effect when the letter is posted.
一个有效的合同需具备要约、承诺、对价、建立法律关系的意图以及行为能力。要约是按特定条件受约束的明确许诺，区别于要约邀请（例如货架上的商品并非要约，而是邀请顾客提出要约：Pharmaceutical Society v Boots 案）。承诺必须是对要约全部条款的无条件同意，且必须传达；邮寄规则是例外，以邮寄方式作出的承诺在信件投邮时即生效。
Consideration is the price of the promise, something of value given by each party. It must be sufficient but need not be adequate (courts do not generally assess the economic adequacy of consideration). Past consideration is not valid, except for certain circumstances under the doctrine of promissory estoppel. Intention to create legal relations is presumed in commercial agreements but not in social or domestic arrangements, though the presumption can be rebutted.
对价是允诺的代价，即每一方提供的有价值之物。它必须充分但不必对等（法院一般不评估对价的经济对等性）。过去的对价无效，除符合允诺禁止反言原则的某些情形外。建立法律关系的意图在商业协议中推定存在，但在社交或家庭安排中则否，不过该推定可被推翻。
11. Contractual Terms and Discharge | 合同条款与解除
Contractual terms may be express (stated by the parties) or implied by statute, custom or the courts. The Sale of Goods Act 1979 implies terms about satisfactory quality and fitness for purpose. Terms are classified as conditions, warranties or innominate terms. Breach of a condition allows the innocent party to terminate the contract and claim damages; breach of a warranty only entitles them to damages. Innominate terms are assessed by the consequences of breach.
合同条款可以是明示的（由当事人说明）或由法规、习惯或法院默示的。《1979年货物销售法》默示了关于满意质量和适用目的的条款。条款分为条件、保证或中间条款。违反条件允准无辜方解除合同并索赔损害赔偿；违反保证仅使其有权获得损害赔偿。中间条款依违约后果评估其效果。
Contracts can be discharged by performance, breach, agreement or frustration. Discharge by performance occurs when both parties have fulfilled all their obligations. Frustration applies when an unforeseeable event makes performance impossible, illegal or radically different from what was agreed, and neither party is at fault. Remedies for breach of contract include damages (aimed at putting the claimant in the position they would have been in had the contract been performed), specific performance and injunctions in equity.
合同可因履行、违约、协议或受挫而解除。因履行解除发生在双方均已履行所有义务时。合同受挫适用于不可预见事件使得履行不可能、非法或根本不同于约定的情形，且双方均无过错。违约救济包括损害赔偿（旨在使原告处于合同若被履行其本应处于的地位）、强制履行以及衡平法上的禁制令。
12. Human Rights Law | 人权法
The Human Rights Act 1998 incorporated the European Convention on Human Rights (ECHR) into UK law. It allows individuals to bring claims in UK courts for breaches of Convention rights, rather than having to go to the European Court of Human Rights in Strasbourg. Key rights include the right to life (Article 2), the prohibition of torture (Article 3), the right to a fair trial (Article 6) and the right to respect for private and family life (Article 8).
《1998年人权法》将《欧洲人权公约》纳入了英国法。它允许个人在英国法院就公约权利的侵犯提起诉讼，而无需诉诸位于斯特拉斯堡的欧洲人权法院。关键权利包括生命权（第2条）、禁止酷刑（第3条）、公正审判权（第6条）以及尊重私人和家庭生活的权利（第8条）。
Courts must interpret legislation compatibly with Convention rights so far as possible. If incompatible, higher courts can issue a declaration of incompatibility, which does not automatically invalidate the statute but pressures Parliament to amend it. This preserves the sovereignty of Parliament while protecting fundamental rights in everyday legal disputes.
法院须尽可能以与公约权利相兼容的方式解释立法。若无法兼容，较高级别的法院可发布不相容声明，该声明不会自动使制定法无效，但会对议会施加修改压力。此举在维护议会主权的同时，在日常法律争议中保护基本权利。
