1. Sources of Law: Legislation and Delegated Legislation | 法律渊源：立法与授权立法
Legislation refers to laws made by Parliament, known as Acts of Parliament or statutes. Primary legislation is debated, passed, and given royal assent. Delegated legislation is law made by other bodies under authority granted by a parent Act, including Orders in Council, Statutory Instruments, and by-laws. Statutory Instruments are widely used to update complex technical details without a full new Act. Critics argue this reduces parliamentary control, but controls exist through judicial review and the negative/affirmative resolution procedures.
立法指由议会制定的法律，即议会法令或成文法。一级立法经过辩论、通过并获得御准。授权立法是其他机构依据母法授权制定的法律，包括枢密院令、行政立法性文件和地方法规。行政立法性文件被广泛用于更新复杂的技术细节而无需通过新的完整法令。批评者认为这削弱了议会控制，但通过司法审查以及消极/积极决议程序仍存在制约。
Key terminology: Statute – a written law passed by Parliament. Delegated legislation – law made by non-parliamentary authorities. Parent Act – the enabling Act that delegates power. Ultra vires – beyond the powers; when a delegated legislation exceeds the authority granted, it can be declared void by the courts. Memory aid: Think of 'statute' as static law from Parliament, while delegated legislation 'delegates' detail work, like a manager handing off tasks.
关键术语：Statute（成文法）——议会通过的书面法律。Delegated legislation（授权立法）——非议会机构制定的法律。Parent Act（母法）——授予权力的授权法令。Ultra vires（越权）——超出权力范围；当授权立法超越授权时，法院可宣告其无效。记忆法：把 statute 想象成议会制定的“静态”法律，而 delegated legislation 则是“授权”他人处理细节，如同经理分配任务。
2. Criminal Law: Actus Reus – The Guilty Act | 刑法：犯罪行为
Actus reus is the physical element of a crime. It can consist of an act, an omission, or a state of affairs. An omission is only criminal when a legal duty to act exists, such as a contractual duty (Pittwood), a duty arising from a special relationship (Gibbins and Proctor), or the voluntary assumption of responsibility (Stone and Dobinson). The act must be voluntary; automatism may negate actus reus. Causation is part of actus reus: the prosecution must prove that the defendant's conduct was both the factual and legal cause of the result.
Actus reus 是犯罪的客观要素，可以是作为、不作为或特定状态。不作为只有在存在法律上的作为义务时才构成犯罪，例如合同义务（Pittwood 案）、特殊关系产生的义务（Gibbins and Proctor 案）或自愿承担的责任（Stone and Dobinson 案）。行为必须是自愿的；无意识行为（automatism）可能否定犯罪行为的存在。因果关系是犯罪行为的一部分：控方必须证明被告的行为既是结果的因果事实原因，也是法律原因。
Key terms: Conduct crime – focus on the prohibited behaviour regardless of result (e.g., perjury). Result crime – requires a particular outcome (e.g., murder). Factual causation – 'but for' the defendant's act, would the harm have occurred? Legal causation – more than minimal, operative, and substantially contributing cause. Remember: actus reus = 'act' or omission that the law condemns.
关键术语：Conduct crime（行为犯）——指关注禁止行为本身，不论结果（如伪证罪）。Result crime（结果犯）——需要特定结果的发生（如谋杀）。Factual causation（事实因果关系）——“若无”被告的行为，损害是否会发生？Legal causation（法律因果关系）——行为必须是重要的作用，具有操作性和实质性。记住：actus reus = 法律谴责的“作为”或不作为。
3. Criminal Law: Mens Rea – The Guilty Mind | 刑法：犯罪意图
Mens rea is the mental element of a crime. The main types are intention, recklessness, negligence, and knowledge. Direct intention means the defendant desired the result. Oblique intention applies where the result was virtually certain to occur and the defendant appreciated this (Woollin). Recklessness is the taking of an unjustified risk; the test for criminal damage is subjective: was the defendant aware of the risk and unreasonably took it anyway (Cunningham). Negligence uses a purely objective standard, comparing the defendant's conduct to that of a reasonable person.
Mens rea 是犯罪的主观要素，主要类型包括意图、轻率、过失和明知。直接意图指被告希望结果发生。间接意图适用于结果几乎肯定会发生且被告意识到这一点（Woollin 案）。轻率是冒不合理之风险；刑事毁坏中的检验标准是主观的：被告是否意识到该风险并不合理地继续行动（Cunningham 案）。过失则采用纯粹的客观标准，将被告行为与理性人进行比较。
Memory tip: 'Mens rea' sounds like 'mental reasoning'. For oblique intention, imagine a virtual certainty. For recklessness, think 'reckless = risk-aware.' with the mnemonic DIRK: Direct intent, Indirect (oblique) intent, Recklessness, Knowledge.
记忆技巧：'Mens rea' 发音近似'mental reasoning'。间接意图可想象“几乎必然发生”。轻率就是“意识到风险却仍冒险”。可用 DIRK 助记四种意图：直接、间接、轻率（Recklessness）、明知（Knowledge）。
4. Strict Liability Offences | 严格责任罪行
Strict liability crimes require no mens rea for at least some elements of the actus reus. The prosecution only needs to prove the physical act. These offences are usually regulatory or public welfare matters, such as food safety, pollution, or traffic violations. The key case is Callow v Tillstone, where a butcher was convicted of selling unsafe meat even though he had taken reasonable care. The courts presume mens rea is required unless the statute clearly indicates otherwise, looking at the wording. The defence of due diligence is sometimes available if expressly provided.
严格责任罪行至少在犯罪行为的某些要素上不需要犯罪意图。控方只需证明物理行为成立。这些犯罪通常是监管类或公共福利事务，如食品安全、污染或交通违法。关键案例是 Callow v Tillstone，屠夫尽管已尽合理注意，仍被判出售不安全肉品罪名成立。法院通常推定需要犯罪意图，除非法律条文明确表明相反立场，具体参照法律措辞。如果法律明文规定，有时可援引尽职抗辩。
Key terminology: Absolute liability – even rarer, with no defence at all, not even due diligence. Regulatory offence – an offence not truly criminal in the traditional sense but enforced by a government body. Presumption of mens rea – starting point in statutory interpretation. Mnemonic: 'Strict' means strict about the act, not the mind.
关键术语：Absolute liability（绝对责任）——更为罕见，完全没有任何抗辩，甚至没有尽职抗辩。Regulatory offence（监管犯罪）——非传统意义上的真正犯罪，由政府机构执行。Presumption of mens rea（犯罪意图推定）——法律解释中的起点。助记：'Strict（严格）'意味着对行为严格，而非对主观心态。
5. Non-Fatal Offences Against the Person | 非致命人身伤害罪行
These offences are divided into assault, battery, actual bodily harm (ABH, s.47 OAPA 1861), and grievous bodily harm (GBH, s.20 and s.18). Assault and battery are common law offences. Assault is causing the victim to apprehend immediate unlawful force; words alone or silent phone calls can suffice (Ireland). Battery is the actual application of unlawful force. ABH requires 'some injury' affecting health or comfort, which can include psychiatric harm. GBH under s.20 is malicious wounding or infliction of grievous bodily harm, requiring Cunningham recklessness; s.18 GBH requires intention to cause GBH and carries a life sentence.
这些罪行分为殴打（assault）、殴打（battery）、实际身体伤害（ABH, 1861年人身侵害法第47条）和重伤害（GBH, 第20条和第18条）。Assault 和 battery 是普通法罪行。Assault 使受害者立即担忧即将遭受非法暴力；仅言语或沉默电话亦可构成（Ireland案）。Battery 是实际实施非法暴力。ABH 需要“某种伤害”影响健康或舒适，可包括精神伤害。第20条项下的GBH是恶意伤人致重伤害，需要 Cunningham轻率；第18条项下GBH要求具有造成重伤害的意图，最高可判终身监禁。
Memory aid: Use the ladder of force: bottom – assault (scared); next – battery (touched); then ABH (hurt); then GBH s.20 (serious harm, reckless); top – s.18 (serious harm, intentional). For the Latin, 'assault' = 'to spring at', 'battery' = 'to beat'.
记忆技巧：使用暴力阶梯：底层——assault（使惊惧）；下一层——battery（触碰）；进而 ABH（造成伤害）；GBH 第20条（严重伤害，轻率）；顶层——第18条（严重伤害，故意）。拉丁词源：'assault' 原意为“扑向”，'battery' 为“殴击”。
6. Tort Law: Negligence – Duty, Breach, Damage | 侵权法：过失——义务、违反、损害
Negligence is the most important tort in the English legal system. To establish liability, the claimant must prove three elements: a duty of care, a breach of that duty, and damage caused by the breach. The modern test for duty of care comes from Caparo Industries v Dickman: foreseeability of damage, proximity between the parties, and that it is fair, just and reasonable to impose a duty. This is applied incrementally by analogy to existing categories. The standard of care is that of the reasonable person (Blyth v Birmingham Waterworks). Professional standards are measured by the Bolam test: a professional is not negligent if they acted in accordance with a responsible body of professional opinion.
过失侵权是英国法律体系中最重要的侵权类型。原告必须证明三要素：注意义务、违反义务和由此造成的损害。近代注意义务的检验标准来源于 Caparo Industries v Dickman 案：损害的可预见性、双方之间的密切关系、以及施加义务是否公平、公正且合理。该标准通过与现有类别类比逐步发展。注意标准是理性人的标准（Blyth v Birmingham Waterworks案）。专业标准以 Bolam 检验为准：专业人士若依据一个负责的专业机构意见行事，则不属于过失。
Vocabulary: Foreseeability – whether a reasonable person would have anticipated harm. Proximity – not merely physical, but a legal closeness of relationship. Causation – factual 'but for' and legal (remoteness). Remoteness – damage must not be too remote; the test from The Wagon Mound is whether the type of damage was reasonably foreseeable.
词汇：Foreseeability（可预见性）——理性人是否会预见损害。Proximity（密切关系）——不限于物理距离，而是法律上的关系紧密程度。Causation（因果关系）——事实因果“若无则不”和法律因果（遥远性）。Remoteness（遥远性）——损害不可过于遥远；检验标准源于 The Wagon Mound，即损害类型是否可合理预见。
7. Duty of Care and Breach: Detailed Application | 注意义务与违反：详细应用
Duty of care can be established by existing precedent, such as driver-pedestrian, doctor-patient, or manufacturer-consumer (Donoghue v Stevenson). In novel situations, the Caparo test applies. Once a duty is established, breach is judged by the objective standard: the defendant must act as a reasonable person. Factors influencing the standard include the magnitude of risk (Bolton v Stone), the social value of the activity (Watt v Hertfordshire), the cost of precautions (Latimer v AEC), and common practice. Special standards apply to children and professionals.
注意义务可通过现有先例确立，如驾驶员与行人、医生与患者、制造商与消费者（Donoghue v Stevenson 案）。在新情况下，适用 Caparo 检验。一旦确立义务，违反以客观标准评判：被告须像理性人那样行事。影响标准的因素包括风险大小（Bolton v Stone案）、活动的社会价值（Watt v Hertfordshire案）、预防措施的成本（Latimer v AEC案）以及惯例。对儿童和专业人士适用特殊标准。
Key terms: Reasonable person – the ordinary prudent individual. Professional standard – Bolam test, refined by Bolitho: the body of opinion must be logical and defensible. Risk factors – probability of injury, seriousness of potential harm, social utility. Remember: 'Breach' is failing to act like the reasonable person; it's the 'bad behaviour' in negligence.
关键术语：Reasonable person（理性人）——普通谨慎个人。Professional standard（专业标准）——Bolam检验，经Bolitho完善：专业意见须符合逻辑且能经辩驳。Risk factors（风险因素）——伤害可能性、潜在后果严重性、社会效用。记住：'Breach' 就是未能像理性人那样行为；是过失侵权中的“过错行为”。
8. Contract Law: Offer and Acceptance | 合同法：要约与承诺
An agreement is formed when an offer is accepted. An offer is an expression of willingness to contract on specific terms made with the intention that it will become binding upon acceptance. Not invitations to treat – such as goods on display (Fisher v Bell) or advertisements (Partridge v Crittenden). An offer can be terminated by revocation (must be communicated), rejection, lapse, or counter-offer. Acceptance must mirror the offer (the 'mirror image rule'), be communicated (except the postal rule), and be made while the offer is still open. The postal rule (Adams v Lindsell) states that acceptance takes effect when posted, not when received.
当要约被承诺时，协议即成立。要约是依特定条款达成合同的意愿表示，且具有一旦被承诺即受约束的意图。并非邀请要约——如货架展示的商品（Fisher v Bell 案）或广告（Partridge v Crittenden 案）。要约可因撤回（必须送达）、拒绝、逾期或反要约而终止。承诺必须与要约完全一致（“镜像规则”），必须送达（除非邮政规则），且须在要约有效期内作出。邮政规则（Adams v Lindsell 案）指明，承诺于投寄时而非收到时生效。
Terminology to master: Invitation to treat – an indication of willingness to negotiate, not an offer. Unilateral offer – accepted by performance (Carlill v Carbolic Smoke Ball). Revocation – cancellation, effective upon reasonable communication. Postal rule – acceptance by post is effective on posting. Memory trick: 'Offer' is like a 'specific proposal' on the table; an 'invitation to treat' is just 'window shopping'.
必须掌握的术语：Invitation to treat（要约邀请）——表明愿意谈判的意愿，非要约。Unilateral offer（单方要约）——通过履行行为接受（Carlill v Carbolic Smoke Ball案）。Revocation（撤回）——撤销，于合理送达时生效。Postal rule（邮政规则）——邮寄承诺于投寄时生效。记忆技巧：'Offer' 如同摆在桌上的“具体提议”；'invitation to treat' 只是“橱窗浏览”。
9. Contract Law: Consideration | 合同法：对价
Consideration is the 'price' paid for the promise. It must move from the promisee but need not move to the promisor. It must be sufficient but need not be adequate; that is, it must have value in the eyes of the law, but the court does not compare economic adequacy. Past consideration is not good consideration unless the act was done at the promisor's request and payment was understood to be due (Lampleigh v Braithwait). Performance of an existing duty owed to a third party can be consideration (Scotson v Pegg). Part payment of a debt generally cannot satisfy the whole debt (Pinnel's case), but there are exceptions: payment by a different means, or the doctrine of promissory estoppel.
对价是为获得允诺而支付的“价格”。它必须由受诺人提供，但不必须流向立诺人。必须充分但不必等价；即须具有法律认可的价值，但法院不比较经济等价性。过去的对价一般不是有效对价，除非该行为是应立诺人要求、且付款意图已被理解（Lampleigh v Braithwait案）。履行对第三方的既存义务可构成对价（Scotson v Pegg案）。部分清偿债务通常不能解除全部债务（Pinnel案），但有例外：以不同方式支付，或援引允诺禁止反言原则。
Important terms: Sufficient consideration – something of value in law. Adequate consideration – equal in economic terms (not required). Past consideration – an act before the promise, generally invalid. Promissory estoppel – topped from going back on it (Central London Property Trust v High Trees House). Mnemonic: 'Consideration = the court wants some value, not equal value.'
重要术语：Sufficient consideration（充分对价）——法律上有价值之物。Adequate consideration（等价对价）——经济上等值（不必须）。Past consideration（过去对价）——允诺之前的行为，通常无效。Promissory estoppel（允诺禁止反言）——若受诺人因信赖允诺而改变立场，立诺人不得反悔（Central London Property Trust v High Trees House案）。助记：'Consideration = 法庭要的是“有”价值，而非“等”价值。
10. Judicial Precedent: Ratio Decidendi and Obiter Dicta | 司法先例：判决理由与附带意见
Judicial precedent operates under the doctrine of stare decisis – to stand by decisions. The binding part of a judgment is the ratio decidendi, the legal reason for the decision. Statements made 'by the way' are obiter dicta, which are persuasive but not binding. Courts higher in the hierarchy bind lower courts. The Supreme Court binds all below and since 1966 may overrule its own previous decisions (Practice Statement). The Court of Appeal is bound by its own decisions with limited exceptions (Young v Bristol Aeroplane). Distinguishing allows a court to avoid an awkward precedent by finding material facts different.
司法先例遵循 stare decisis 原则——遵循已决案件。判决中有约束力的部分是 ratio decidendi，即判决的法律理由。顺便发表的意见是 obiter dicta，具有说服力但不具约束力。法院等级中上级法院约束下级法院。最高法院约束所有下级法院，且自1966年起可推翻自身先前判决（Practice Statement）。上诉法院受自身先前判决约束，但有有限的例外（Young v Bristol Aeroplane案）。区分（distinguishing）允许法院通过判定案件事实存在重要差异来避开对已存棘手先例的遵循。
Terminology: Binding precedent – must be followed. Persuasive precedent – may be followed, e.g., obiter from a higher court, dissenting judgments, decisions from other jurisdictions. Overruling – a higher court declares a previous decision wrong in law. Reversing – a higher court changes the decision on appeal in the same case. Distinguishing – pointing out material differences to avoid following precedent. Memory: 'Ratio' = 'reason' for the decision; 'obiter' = 'oh, by the way'.
术语：Binding precedent（约束先例）——必须遵守。Persuasive precedent（说服性先例）——可参考，如上级法院的附带意见、异议判决、其他法域判例。Overruling（推翻）——上级法院宣布先前判决错误。Reversing（改判）——上级法院在上诉案中变更同一案件的判决。Distinguishing（区分）——指出重要事实差异，避开先例。记忆：'Ratio' = 判决的“理由”；'obiter' = “噢，顺便说说”。
11. Statutory Interpretation: Literal to Purposive Approaches | 法律解释：文义到目的性方法
Judges interpret statutes using several rules. The literal rule gives words their plain, ordinary meaning even if it leads to absurdity (Whitely v Chappell). The golden rule allows the court to modify the literal meaning to avoid an absurd result, either narrowly (choose between meanings) or broadly (R v Allen). The mischief rule (Heydon's case) looks at the 'mischief' the statute aimed to cure and interprets to suppress that mischief. The modern purposive approach looks at the overall purpose of the legislation, influenced by European law, and gives the judge greater freedom to interpret in line with Parliament's intent (Pepper v Hart).
法官使用多种规则来解释法律。文义规则按词语的普通平实含义解释，即使可能导致荒谬（Whitely v Chappell案）。黄金规则允许法院为避免荒谬结果而调整文义，分为狭义（在多个含义中选择）或广义（R v Allen案）。不道规则（Heydon案）旨在探寻法律所要弥补的“漏洞”，并以此防范来解释。现代的目的性解释法关注立法的整体目的，受欧洲法影响，给予法官更大的自由以符合议会意图的方式解释（Pepper v Hart 案）。
Aids to interpretation: intrinsic aids are inside the Act itself, such as long title, preamble, definition sections. Extrinsic aids are outside, e.g., dictionaries, previous Acts, Law Commission reports, and Hansard (Pepper v Hart). Ejusdem generis – where general words follow specific words, the general words are limited to the same class. Expressio unius est exclusio alterius – the mention of one thing excludes others. Noscitur a sociis – a word is known by its company.
解释辅助工具：内部辅助材料在法令本身中，如长标题、序言、定义条文。外部辅助材料在外，如字典、先前法令、法律委员会报告及《国会议事录》（Pepper v Hart）。Ejusdem generis（同类规则）——当概括性词汇跟随特定词汇时，概括性词汇被限制在同一类别。Expressio unius est exclusio alterius（明示其一即排斥其他）——提到某一事物即排斥其他。Noscitur a sociis（依上下文定含义）——词义由上下文确定。
