For Year 11 students preparing for the CAIE IGCSE Law examination, a clear and structured revision of the key topics is essential. This guide consolidates the core knowledge areas spanning the English legal system, criminal law, tort, contract, and human rights, all designed to build confidence and exam readiness.
对于备战 CAIE IGCSE 法律考试的 11 年级学生而言，清晰且结构化地复习关键主题至关重要。本指南系统梳理了涵盖英国法律体系、刑法、侵权法、合同法及人权法的核心知识点，旨在帮助同学们建立信心并为考试做好充分准备。
1. The Nature of Law and Legal Systems | 法律的本质与法律体系
Law can be defined as a set of rules created by the state to regulate behaviour, maintain order, and deliver justice. It is distinct from moral rules because it is enforceable through the courts and carries formal sanctions.
法律可被定义为一套由国家制定的规则，旨在规范行为、维护秩序并实现正义。它区别于道德规则，因为法律可通过法院强制执行并伴有正式的制裁。
Legal systems are broadly divided into public law and private law. Public law governs the relationship between the state and individuals (including constitutional, administrative, and criminal law), while private law deals with disputes between individuals or businesses, such as contract and tort law.
法律体系大致分为公法和私法。公法调整国家与个人之间的关系（包括宪法、行政法和刑法），而私法则处理个人或企业之间的纠纷，例如合同法和侵权法。
Criminal law involves the state prosecuting an individual for conduct harmful to society, with the aim of punishment. Civil law, by contrast, enables individuals to seek remedies, typically damages, from another party for a wrong suffered.
刑法涉及国家对危害社会的个人行为提起公诉，目的在于惩罚。相比之下，民法则使个人能够就所遭受的侵害向另一方寻求补救，通常是损害赔偿金。
2. Sources of English Law | 英国法律渊源
The primary sources of law in England and Wales are Acts of Parliament (statute law), common law, and retained EU law. Parliament is sovereign and can pass statutes on any subject; these override other sources in the event of conflict.
英格兰和威尔士的主要法律渊源包括议会法案（成文法）、普通法以及被保留的欧盟法律。议会拥有主权，可以通过任何事项的成文法；一旦发生冲突，成文法优先于其他渊源。
Delegated legislation, such as statutory instruments and by-laws, is made by government ministers or local authorities under powers granted by Parliament. It allows detailed rules to be created without a full Act, but it must remain within the scope of the enabling Act.
授权立法（如行政规章和地方规章）由政府部长或地方当局根据议会授予的权力制定。它允许在不通过完整法案的情况下制定详细规则，但必须在其授权法案的范围内。
Common law, or case law, is developed by judges through the doctrine of judicial precedent. Equity developed historically to provide fairer remedies where common law was too rigid, and its principles (such as trusts and injunctions) continue to operate alongside common law rules.
普通法（判例法）是法官通过司法先例制度发展而来的。衡平法在历史上发展起来，以在普通法过于僵化时提供更公平的救济，其原则（如信托和禁制令）与普通法规则并存运行。
3. The Court Hierarchy and Judicial Precedent | 法院等级与司法先例
The English court hierarchy consists of the Supreme Court (formerly the House of Lords) at the top, followed by the Court of Appeal, the High Court, and the Crown Court, with magistrates' courts and county courts at the bottom. Higher court decisions bind lower courts.
英国法院等级由顶端的最高法院（前身为上议院）开始，接着是上诉法院、高等法院和刑事法院，基层则是治安法院和郡法院。上级法院的判决对下级法院具有约束力。
The doctrine of precedent requires courts to follow the ratio decidendi (the legal reason for the decision) of previous cases from a higher court in the same hierarchy. Obiter dicta (comments made 'by the way') are not binding but may be persuasive.
先例原则要求法院遵循同一等级体系中上级法院先前案件中的判决理由（作出判决的法律依据）。附言（'顺便提及'的评论）不具有约束力，但可能具有说服力。
Judges may distinguish a previous case if they find the material facts are sufficiently different, or overrule it if they are in a higher court. This flexibility allows the common law to adapt while maintaining consistency.
法官若认为案件的关键事实与先例存在充分不同，可以作出区别；如果是上级法院，还可以推翻先例。这种灵活性使普通法在保持一致性的同时能够适应变化。
4. Criminal Law: General Principles | 刑法：一般原则
A crime is a conduct prohibited by the state, prosecuted in criminal courts, and punishable by a fine, imprisonment, or other sanctions. The burden of proof lies on the prosecution to prove the defendant's guilt beyond reasonable doubt.
犯罪是被国家禁止的行为，在刑事法院提起诉讼，并可处以罚款、监禁或其他制裁。举证责任在于控方，必须证明被告人有罪，证明标准达到排除合理怀疑。
The principle of the presumption of innocence means a defendant is considered innocent until proven guilty. Most crimes require proof of both a guilty act (actus reus) and a guilty mind (mens rea), except for strict liability offences.
无罪推定原则意味着被告在被证实有罪之前被视为清白。大多数犯罪要求同时证明犯罪行为（actus reus）和犯罪意图（mens rea），但严格责任犯罪除外。
5. Elements of a Crime: Actus Reus & Mens Rea | 犯罪构成：犯罪行为与犯罪意图
Actus reus refers to the external physical element of a crime. It may consist of an act, a failure to act (omission) where a duty exists, or a state of affairs. The act must be voluntary, and for result crimes, causation must be established.
犯罪行为（actus reus）指的是犯罪的外部客观要件。它可以是一种行为、有义务时的失职（不作为）或特定状态。该行为必须是自愿的；对于结果犯，还必须证明因果关系。
Causation requires both factual causation (the 'but for' test) and legal causation (the act must be the substantial and operating cause of the harm). An intervening act may break the chain of causation if it is unforeseeable and renders the original act no longer a significant cause.
因果关系既要求事实上的因果关系（'若无则不'检验），也要求法律上的因果关系（该行为必须是损害的重大且运行中的原因）。若介入行为不可预见且使得原行为不再是重大原因，可能中断因果关系链条。
Mens rea is the mental element: the defendant's state of mind at the time of the act. The main forms are intention (direct or oblique), recklessness, and negligence. For some offences, such as murder, only intention suffices; for others, recklessness is enough.
犯罪意图（mens rea）是主观要件：被告在行为时的心理状态。主要形式包括故意（直接或间接）、轻率和过失。对于某些犯罪（如谋杀），只有故意才足够；对于其他犯罪，轻率也可构成。
6. Homicide and Non-Fatal Offences | 杀人罪与非致命人身侵害
Murder is the unlawful killing of a human being under the Queen's peace with malice aforethought, which means an intention to kill or cause grievous bodily harm. It carries a mandatory life sentence.
谋杀是在女王治下非法杀害他人并具有恶意预谋，即意图杀人或造成严重身体伤害。谋杀罪须判处终身监禁。
Voluntary manslaughter arises when the defendant would be guilty of murder but a partial defence applies, such as diminished responsibility or loss of control. Involuntary manslaughter covers killings where no intention exists but there is gross negligence or an unlawful and dangerous act.
有罪过失杀人适用于被告本可构成谋杀，但因存在部分抗辩事由（如减轻责任或失控）而降格。无过失杀人则涵盖无杀人故意，但存在重大过失或非法且危险行为的杀人情形。
Non-fatal offences against the person include assault (causing another to apprehend immediate violence), battery (applying unlawful force), actual bodily harm (ABH, under s.47 OAPA 1861), and grievous bodily harm (GBH, under s.20 and s.18 OAPA 1861). Each requires different levels of mens rea.
非致命人身侵害包括袭击（使他人恐惧即时的暴力）、殴击（施加非法暴力）、实际身体伤害（ABH，根据1861年《人身犯罪法》第47条）和严重身体伤害（GBH，根据该法第20条和第18条）。各罪对犯罪意图的要求有所不同。
7. Property Offences: Theft and Robbery | 财产犯罪：盗窃与抢劫
Theft is defined under the Theft Act 1968 as the dishonest appropriation of property belonging to another with the intention to permanently deprive the owner of it. All five elements—dishonesty, appropriation, property, belonging to another, and intention to permanently deprive—must be present.
根据1968年《盗窃法》，盗窃是怀着永久剥夺他人财产的意图，不诚实地侵占属于他人的财产。必须同时具备五个要素：不诚实、侵占、财产、属于他人以及永久剥夺的意图。
Robbery is aggravated theft: the defendant steals and immediately before or at the time uses force or seeks to put the victim in fear of force. If no theft is completed, there can be no robbery, but an assault or attempted theft may still be charged.
抢劫是加重的盗窃：被告盗窃，并在临盗窃前或盗窃时使用暴力，或试图使受害者恐惧暴力。如果盗窃未完成，则无法构成抢劫，但仍可能被控袭击或盗窃未遂。
8. Defences in Criminal Law | 刑法抗辩事由
Defences can be complete (leading to acquittal) or partial (reducing murder to manslaughter). Key complete defences include self-defence, duress, necessity, insanity, and automatism. Consent may operate as a defence to non-fatal offences in certain circumstances, such as sports or medical treatment.
抗辩事由可以是完全的（导致无罪开释）或部分的（将谋杀降格为过失杀人）。主要的完全抗辩事由包括自我防卫、胁迫、紧急避险、精神错乱和自动症。同意可在特定情况下（如体育比赛或医疗）作为非致命侵害的抗辩。
Self-defence is available where the defendant uses reasonable force to protect themselves or another, or to prevent a crime. The force must be proportionate to the threat as the defendant honestly believed it to be. Duress applies where the defendant is forced to commit a crime by threats of death or serious injury, but it is not available for murder.
自我防卫适用于被告使用合理武力保护自身或他人，或防止犯罪的情形。武力必须与被告诚实地相信的威胁成比例。胁迫适用于被告因死亡或严重伤害威胁而被迫犯罪，但胁迫不得用于谋杀罪抗辩。
Insanity, based on M'Naghten rules, requires that at the time of the act the defendant was suffering from a defect of reason arising from a disease of the mind, so that they did not know the nature and quality of the act or did not know it was wrong. Automatism is a denial of voluntary control due to an external factor, like a blow or medication, and is a complete defence.
基于姆纳坦规则，精神错乱要求在行为时被告因精神疾病导致理性缺陷，以致不理解行为的性质和特性，或不理解行为是错误的。自动症是因外部因素（如打击或药物）而失去自主控制，属完全抗辩事由，可否定自愿性。
9. Tort Law: Negligence and Nuisance | 侵权法：过失与妨扰
The tort of negligence provides a remedy for harm caused by a breach of a duty of care owed by the defendant to the claimant. To succeed, the claimant must prove that a duty of care existed, that duty was breached, and the breach caused damage which is not too remote.
过失侵权为被告违反其对原告所负的注意义务而造成的损害提供救济。原告须证明存在注意义务、该义务被违反、违反行为导致了损害，且损害并非过于间接，方可胜诉。
The modern duty of care test comes from Caparo v Dickman: the harm must be reasonably foreseeable, there must be proximity between the parties, and it must be fair, just and reasonable to impose a duty. Breach is assessed by the reasonable person standard, and by considering risk factors such as likelihood of harm, seriousness, cost of prevention, and the social utility of the defendant's conduct.
现代注意义务检验来自 Caparo v Dickman 案：损害必须可以合理预见，当事人之间必须存在接近性，且施加义务是公平、公正和合理的。违反义务则依据理性人的标准，并考量风险因素，如损害发生的可能性、严重性、预防成本以及被告行为的社会效益。
Private nuisance protects a person's use and enjoyment of their land from unreasonable interference, such as noise, smoke, or smells. The interference must be substantial and unreasonable; the court balances the competing interests of both sides. Public nuisance is a broader concept that affects the comfort or safety of a class of Her Majesty's subjects and may be both a tort and a crime.
私人妨扰保护个人使用和享用其土地不受不合理干涉，如噪音、烟尘或气味。干涉必须是实质性的且不合理的；法院会平衡双方利益。公共妨扰是一个更广泛的概念，影响陛下臣民某一群体的舒适或安全，可同时构成侵权和犯罪。
10. Contract Law: Offer, Acceptance, and Consideration | 合同法：要约、承诺与对价
A contract is a legally enforceable agreement. Its essential elements are offer, acceptance, consideration, intention to create legal relations, and sufficient certainty of terms. The absence of any element may result in no contract or a void agreement.
合同是具有法律强制执行力的协议。其基本要素包括要约、承诺、对价、建立法律关系的意图以及条款的足够确定性。缺少任一要素可能导致合同不成立或协议无效。
An offer is a clear expression of willingness to be bound by stated terms. It must be distinguished from an invitation to treat, which is merely an invitation to negotiate, such as goods displayed in a shop (Fisher v Bell). Acceptance must be a mirror image of the offer and communicated to the offeror, either expressly or by conduct, except where the postal rule applies.
要约是明确表示愿意接受所述条款约束。必须区分要约邀请，后者仅是谈判的邀请，例如商店陈列的商品（Fisher v Bell 案）。承诺必须是对要约的镜像回应，并传达给要约人，除非适用邮政规则，可通过明示或行为方式传达。
Consideration is something of value exchanged between the parties. It must move from the promisee but need not be adequate; it must be sufficient. Past consideration is generally not good consideration. The intention to create legal relations is presumed in commercial agreements but rebuttable, while in social or domestic agreements it is presumed not to exist unless evidence shows otherwise.
对价是当事人之间交换的有价值之物。对价必须来自受诺人，但无需充分（经济等价），只需足够即可。过去的对价通常不构成有效对价。在商业协议中推定具有建立法律关系的意图（可被推翻），而在社交或家庭协议中则推定不存在，除非证据表明相反。
11. Human Rights and Judicial Review | 人权与司法审查
The Human Rights Act 1998 incorporates the rights and freedoms set out in the European Convention on Human Rights into UK domestic law. It requires public authorities to act compatibly with Convention rights, unless primary legislation prevents it, and enables individuals to bring a claim in UK courts for a breach.
1998年《人权法》将《欧洲人权公约》所载权利和自由纳入英国国内法。它要求公共机构以符合公约权利的方式行事（除非基本立法不允许），并允许个人在英国法院就侵权行为提起诉讼。
Key Convention rights include the right to life (Art.2), prohibition of torture (Art.3), right to liberty and security (Art.5), right to a fair trial (Art.6), right to respect for private and family life (Art.8), freedom of expression (Art.10), and freedom of assembly (Art.11). Courts can issue a declaration of incompatibility if a statute cannot be read compatibly, prompting Parliament to amend the law.
主要的公约权利包括：生命权（第2条）、禁止酷刑（第3条）、自由和安全权（第5条）、公平审判权（第6条）、尊重私人和家庭生活的权利（第8条）、言论自由（第10条）及集会自由（第11条）。如果成文法无法被解读为与权利相容，法院可发出不相容宣告，从而促使议会修改法律。
Judicial review is a procedure by which the High Court examines the lawfulness of decisions made by public bodies. Grounds include illegality (acting beyond power), irrationality (Wednesbury unreasonableness), and procedural impropriety (breach of natural justice). It is concerned with the decision-making process, not the merits of the decision.
司法审查是高等法院审查公共机构决定合法性的程序。审查理由包括：不合法（越权行为）、不合理（Wednesbury 意义上的不合理）以及程序不当（违反自然正义）。它关注的是决策过程，而非决定本身的优劣。
12. Exam Skills and Key Concepts Review | 考试技巧与核心概念回顾
Success in CAIE IGCSE Law requires more than knowing the law. You must demonstrate the ability to identify the relevant legal issues from a factual scenario, state the applicable rules clearly, apply the law to the facts, and reach a reasoned conclusion—often remembered by the IRAC structure (Issue, Rule, Application, Conclusion).
CAIE IGCSE 法律考试的成功不仅取决于法律知识。你必须展现从事实场景中识别相关法律问题、清晰陈述适用规则、将法律应用于事实并得出有推理的结论的能力——这常被概括为 IRAC 结构（问题、规则、应用、结论）。
Use a case name only when it illustrates a legal principle effectively. Do not recount full case facts unless necessary for distinguishing or explaining. Focus on the key ratio and ensure your analysis is precise and well-structured.
仅在案例能有效说明法律原则时使用案名。除非有必要进行区分或解释，否则不要复述完整的案例事实。聚焦关键判决理由，确保分析精准且结构良好。
Manage your time carefully across both knowledge-based questions and scenario-based problem questions. For problem questions, always identify the parties, the possible offences or claims, and then methodically work through the elements, considering any defences or remedies. Practice under timed conditions to build fluency.
在知识简答题和情境应用问题之间合理分配时间。对于问题解决题，始终先识别当事人，列出可能成立的犯罪或索赔，然后有条理地逐一分析构成要件，并考量任何抗辩事由或救济。在限时条件下练习以提升答题流畅度。
