1. Judicial Precedent (Stare Decisis) | 司法判例（遵循先例）
The doctrine of precedent requires courts to follow previous decisions where the material facts and legal issues are similar, ensuring consistency and fairness. A binding precedent is created when the ratio decidendi – the legal reason for the decision – comes from a higher court in the same hierarchy.
判例原则要求法院在案件关键事实与法律争议类似时遵循既往判决，以此保障一致性与公平性。当判决理由（ratio decidendi）来自同一法院等级系统中的上级法院时，即构成具有约束力的判例。
Key Latin maxim: Stare decisis et non quieta movere – to stand by decisions and not disturb settled points.
核心拉丁法谚：遵循先例，不扰乱已确立的要点。
Ratio decidendi → binding | Ratio decidendi → 约束力
Obiter dicta → persuasive only | Obiter dicta → 仅具说服力
The Supreme Court (formerly the House of Lords) is generally bound by its own previous decisions, but may depart "when it appears right to do so" under the Practice Statement 1966. The Court of Appeal is bound by its own decisions, subject to the three exceptions in Young v Bristol Aeroplane Co Ltd (1944): conflicting decisions, decisions made per incuriam, and decisions that are effectively overruled by the Supreme Court.
最高法院（前身为上议院）通常受自身先前判决的约束，但根据1966年实务声明，在"看来正确时"可以偏离。上诉法院受自身判决约束，但存在Young v Bristol Aeroplane Co Ltd (1944)案确立的三个例外：相互冲突的判决、因疏忽作出的判决，以及实际上已被最高法院推翻的判决。
- Original precedent: A point of law is decided for the first time (e.g., Donoghue v Stevenson on the neighbour principle).
- 原始判例：首次就某个法律点作出判决（如Donoghue v Stevenson案中的邻人原则）。
- Distinguishing: Judges avoid an otherwise binding precedent by finding the material facts significantly different.
- 区别：法官通过认定案件关键事实明显不同，从而避开本应具有约束力的判例。
2. Statutory Interpretation Rules | 成文法解释规则
When the meaning of a statute is unclear, judges apply interpretation rules to ascertain Parliament's intention. The three main traditional rules are the literal rule, the golden rule, and the mischief rule. Modern courts also use the purposive approach, which looks at the broader purpose of the legislation.
当成文法含义不明确时，法官运用解释规则来确定立法意图。三大传统规则为字面规则、黄金规则和弊端规则。现代法院还采用目的解释法，审视立法的更广泛目的。
| Literal rule (字面规则)：Words given ordinary dictionary meaning even if result is absurd – Whitely v Chappell (1868); Fisher v Bell (1961). |
| Golden rule (黄金规则)：Narrow approach: choose between possible meanings to avoid absurdity – R v Allen (1872). Wide approach: modify words to avoid a repugnant result – Re Sigsworth (1935). |
| Mischief rule (弊端规则)：Examine the common law before the Act, identify the problem the Act was designed to remedy – Heydon’s Case (1584); Smith v Hughes (1960). |
| Purposive approach (目的解释)：Focus on the legislative purpose, often using Hansard under Pepper v Hart (1993) – Jones v Tower Boot Co (1997). |
Internal (intrinsic) aids: the statute itself – long title, preamble, interpretation sections. External (extrinsic) aids: dictionaries, previous Acts, Law Commission reports, Hansard.
内部辅助资料：法规本身 – 长标题、序言、解释性条款。外部辅助资料：字典、先前立法、法律委员会报告、英国议会议事录。
3. Hierarchy of Courts & Appeals | 法院等级与上诉
The English court system is structured in a clear hierarchy, crucial for understanding which decisions bind which courts. Criminal courts and civil courts form two main streams, both feeding into the Supreme Court.
英格兰法院体系具有清晰的等级结构，这对理解哪些判决约束哪些法院至关重要。刑事法院和民事法院构成两大主线，最终都通向最高法院。
Supreme Court (formerly HoL) ↑ | 最高法院（原上议院）↑
Court of Appeal (Criminal Division / Civil Division) ↑ | 上诉法院（刑事庭/民事庭）↑
High Court (QBD, Chancery, Family) ↑ | 高等法院（王座庭、大法官庭、家事庭）↑
Crown Court / County Court ↑ | 刑事法院/郡法院 ↑
Magistrates’ Court / First-tier Tribunals | 治安法院/初级审裁处
In criminal cases, appeals from the Magistrates’ Court go to the Crown Court (full rehearing) or by way of case stated to the Queen’s Bench Division on a point of law. From the Crown Court, appeal lies to the Court of Appeal Criminal Division, and finally to the Supreme Court on a point of law of general public importance.
刑事案件中，从治安法院的上诉途径为刑事法院（全面重审）或就法律问题通过案件呈述方式上诉至王座庭。从刑事法院可上诉至上诉法院刑事庭，最后就具有普遍公共重要性的法律问题上诉至最高法院。
4. Criminal Liability: Actus Reus & Mens Rea | 刑事责任：犯罪行为与犯罪意图
Every criminal offence requires an actus reus (guilty act) and mens rea (guilty mind) unless the offence is one of strict liability. Both must coincide in time for liability to arise.
除严格责任犯罪外，每项刑事犯罪均须具备犯罪行为（actus reus）和犯罪意图（mens rea），且二者必须在时间上一致，才产生刑事责任。
Actus reus components: conduct (an act or, exceptionally, an omission where a duty exists – R v Pittwood), circumstances (e.g., absence of consent in theft), and result (causation). Factual causation uses the "but for" test (R v White). Legal causation requires the defendant’s act to be a substantial and operating cause (R v Smith; R v Cheshire). The chain of causation may be broken by an intervening act of a third party or an unforeseeable natural event.
犯罪行为的构成：行为（作为，或在存在义务时的罕见不作为 – R v Pittwood案）、状态（如盗窃中缺乏同意）以及结果（因果关系）。事实因果关系采用"若非"测试（R v White案）。法律因果关系要求被告的行为是实质性和起作用的致因（R v Smith案；R v Cheshire案）。因果关系链条可能因第三方的介入行为或不可预见的自然事件而中断。
Mens rea types: intention (direct: aim/purpose; oblique: consequence virtually certain and defendant foresaw it – R v Woollin), recklessness (foresight of an unjustifiable risk – subjective Cunningham test), negligence (falling below the standard of the reasonable person, used mainly in tort, but gross negligence manslaughter is an exception), and transferred malice (R v Latimer; R v Pembliton).
犯罪意图类型：故意（直接故意：目标/目的；间接故意：后果几乎确定且被告预见到 – R v Woollin案），轻率（预见到不合理风险 – 主观Cunningham检验标准），疏忽（未达到合理人的标准，主要用于侵权法，但重大疏忽过失杀人属例外），以及恶意转移（R v Latimer案；R v Pembliton案）。
Strict liability offences require no proof of mens rea for at least one element (e.g., driving whilst disqualified – R v Williams, food safety offences – Callow v Tillstone).
严格责任犯罪至少对某一要素无需证明犯罪意图（如被取消驾驶资格期间驾车 – R v Williams案，食品安全犯罪 – Callow v Tillstone案）。
5. Non-Fatal Offences Against the Person | 针对人身的非致命犯罪
The principal non-fatal offences under the Offences Against the Person Act 1861 and common law are assault, battery, assault occasioning actual bodily harm (ABH – s.47), malicious wounding or inflicting grievous bodily harm (GBH – s.20), and wounding or causing GBH with intent (s.18).
根据《1861年侵害人身法》和普通法，主要非致命犯罪包括威胁（assault）、殴打（battery）、威胁致实际身体伤害（ABH – 第47条）、恶意伤人/造成严重身体伤害（GBH – 第20条），以及故意伤人/造成严重身体伤害（第18条）。
| Offence | Actus reus | Mens rea | Key case |
| Assault | 威胁 | Causing V to apprehend immediate unlawful force | Intention or recklessness | Logdon v DPP (1976) |
| Battery | 殴打 | Application of unlawful force, even slight touching | Intention or recklessness | Collins v Wilcock (1984) |
| ABH s.47 | Assault or battery resulting in actual bodily harm (more than transient or trifling – R v Chan-Fook) | Intention or recklessness as to the assault/battery (no need to foresee ABH – R v Savage) | R v Miller (1954) |
| GBH s.20 | Wounding (break both layers of skin) or inflicting GBH (really serious harm – DPP v Smith) | Intention or recklessness as to some harm (R v Mowatt) | R v Cunningham (1957) |
| GBH s.18 | Wounding or causing GBH | Intention to cause GBH or resist/prevent arrest (R v Belfon) | R v Morrison (1998) |
6. Defences in Criminal Law | 刑事辩护理由
A defence either negates an element of the offence or provides a justification/excuse. Key general defences for AS Level include consent, self-defence, duress, and intoxication (voluntary and involuntary).
辩护理由或者否定犯罪的某一构成要素，或者提供正当理由/宽宥事由。AS阶段的主要一般辩护理由包括同意、自卫、胁迫以及醉酒（自愿与非自愿）。
Consent: Valid consent may negate the actus reus of assault/battery. Consent must be genuine, informed, and the person must have capacity. Consent cannot be a defence to actual bodily harm or more serious injury unless the activity falls within a recognized public interest exception (e.g., sports, surgery, rough horseplay – R v Aitken; R v Brown).
同意：有效同意可否定威胁/殴打的犯罪行为。同意须真实、知情且当事人具备同意能力。除非行为属于公认的公共利益例外（如体育、手术、粗暴玩笑 – R v Aitken案；R v Brown案），否则同意不能作为实际身体伤害或更严重伤害的辩护理由。
Self-defence: A person may use reasonable force to protect themselves, another person, or property. The force must be necessary (subjective question) and proportionate (objectively reasonable in the circumstances as the defendant honestly believed them to be – R v Owino; s.76 Criminal Justice and Immigration Act 2008). Pre-emptive strikes are allowed (Beckford v R).
自卫：个人可使用合理武力保护自身、他人或财产。武力必须是必要的（主观问题）且程度相当（在被告人真实相信的情形下客观合理 – R v Owino案；2008年刑事司法与移民法第76条）。允许先发制人的攻击（Beckford v R案）。
Duress: The defendant was forced to commit a crime due to a threat of death or serious injury. Duress is unavailable for murder (R v Howe), attempted murder, and where the defendant voluntarily joined a criminal gang that might put them under compulsion (R v Hasan).
胁迫：被告人因面临死亡或严重伤害的威胁而被迫实施犯罪。胁迫不适用于谋杀（R v Howe案）、谋杀未遂，以及被告人自愿加入可能对其施压的犯罪团伙的情形（R v Hasan案）。
Intoxication: Voluntary intoxication (by alcohol or dangerous drugs) is a defence only to crimes of specific intent (e.g., s.18 GBH, murder) if it prevented the defendant from forming the required intent (DPP v Majewski). It is not a defence to basic intent crimes (e.g., s.20, s.47, battery), where getting drunk is deemed reckless. Involuntary intoxication (slipped a drug) may be a defence to any crime if it negates mens rea (R v Kingston).
醉酒：自愿醉酒（因酒精或危险药物）仅在特定故意犯罪（如第18条严重身体伤害、谋杀）中，若导致被告人无法形成所需故意，可作辩护（DPP v Majewski案）。对于基本故意犯罪（如第20条、第47条、殴打），醉酒不被采纳为辩护理由，因醉酒本身即被视为轻率。非自愿醉酒（被暗中下药）若否定了犯罪意图，可作为任何犯罪的辩护理由（R v Kingston案）。
7. Tort Law: Negligence – Duty, Breach, Damage | 侵权法：过失 – 义务、违反、损害
A successful negligence claim requires the claimant to prove three elements on the balance of probabilities: a duty of care, breach of that duty, and damage caused by the breach (causation and remoteness).
成功的过失侵权索赔要求原告在盖然性权衡的基础上证明三个要素：注意义务、违反该义务，以及由违反义务导致的损害（因果关系与遥远性）。
Duty of care: Neighbour principle → Caparo three-stage test
注意义务：邻人原则 → Caparo三阶段测试
The Caparo test asks: (1) Was the harm reasonably foreseeable? (2) Was there proximity between the parties? (3) Is it fair, just and reasonable to impose a duty? (Caparo Industries plc v Dickman [1990]).
Caparo测试问：(1) 损害是否合理可预见？(2) 当事人之间是否存在邻近关系？(3) 施加义务是否公平、公正且合理？（Caparo Industries plc v Dickman [1990]案）。
Breach of duty: The defendant must meet the standard of the reasonable person in their position (Blyth v Birmingham Waterworks). Factors include: likelihood of harm (Bolton v Stone), seriousness of harm (Paris v Stepney BC), cost of precautions (Latimer v AEC), and social utility (Watt v Hertfordshire CC). Special standards apply to professionals (Bolam test, modified by Bolitho) and learners (Nettleship v Weston).
违反义务：被告须达到处于其地位的合理人的标准（Blyth v Birmingham Waterworks案）。考量因素包括：损害发生的可能性（Bolton v Stone案）、损害的严重性（Paris v Stepney BC案）、预防措施的成本（Latimer v AEC案）以及社会效用（Watt v Hertfordshire CC案）。专业人员（Bolam测试，经Bolitho案修正）和学习者（Nettleship v Weston案）适用特殊标准。
Damage (causation): Factual causation uses the "but for" test (Barnett v Chelsea & Kensington Hospital). Legal causation requires the damage to be a reasonably foreseeable consequence (Wagon Mound No 1). The chain of causation can be broken by a novus actus interveniens. The thin skull rule (eggshell skull rule) ensures the defendant takes their victim as they find them (Smith v Leech Brain & Co).
损害（因果关系）：事实因果关系采用"若非"测试（Barnett v Chelsea & Kensington Hospital案）。法律因果关系要求损害是合理可预见的后果（Wagon Mound No 1案）。因果关系链条可因新的介入行为而中断。薄颅规则（蛋壳脑袋规则）要求被告按受害人的实际情况承受责任（Smith v Leech Brain & Co案）。
8. Occupiers’ Liability | 占有人责任
Occupiers' liability deals with the duty owed by the occupier of premises to persons who enter those premises. Two statutes apply: the Occupiers' Liability Act 1957 covers lawful visitors; the 1984 Act covers trespassers.
占有人责任处理的是房屋占有人对进入该房屋的人所负的义务。两部制定法分而适用：《1957年占有人责任法令》适用于合法访客；《1984年法令》适用于侵入者。
1957 Act (visitors): The occupier owes a common duty of care to see that the visitor is reasonably safe in using the premises for the purposes for which they are invited (s.2(2)). An occupier is a person with sufficient control over the premises (Wheat v E Lacon & Co). Visitors lose their status if they exceed their permission. Special provisions apply to children (Glasgow Corp v Taylor), and to persons exercising a calling (Roles v Nathan). Warnings and independent contractors are relevant to discharging the duty (s.2(4); Haseldine v Daw).
1957年法令（访客）：占有人对访客负有普通注意义务，确保访客在为其被邀请的目的使用房屋时合理安全（第2条第2款）。占有人是指对房屋拥有足够控制权的人（Wheat v E Lacon & Co案）。访客若超越许可范围，则丧失访客身份。对儿童（Glasgow Corp v Taylor案）和执行职业任务者（Roles v Nathan案）有特别条款。警告和独立承包人与义务的履行相关（第2条第4款；Haseldine v Daw案）。
1984 Act (trespassers): An occupier owes a limited duty to persons other than visitors if they are aware of the danger, know a trespasser may come into the vicinity, and the risk is one against which it is reasonable to offer some protection (s.1(3)). The duty is to take such care as is reasonable to see that the trespasser does not suffer injury on the premises (s.1(4)). Warnings may suffice to discharge the duty (s.1(5)). Key case: Ratcliff v McConnell (diving into shallow pool at night – no duty).
1984年法令（侵入者）：若占有人知悉危险、知道侵入者可能进入附近、且该风险属于合理提供某些保护的情形（第1条第3款），则占有人对非访客负有有限义务。义务内容为采取合理的注意，确保侵入者不在房屋内遭受伤害（第1条第4款）。警告可能足以履行义务（第1条第5款）。关键案例：Ratcliff v McConnell案（夜间跳入浅水池 – 不负义务）。
9. Contract Law: Offer & Acceptance | 合同法：要约与承诺
A binding contract is formed when there is an offer, acceptance, consideration, intention to create legal relations, and sufficient certainty. Offer and acceptance determine the existence and terms of an agreement.
当存在要约、承诺、对价、建立法律关系的意图以及足够的确定性时，便形成具有约束力的合同。要约与承诺决定协议是否成立及协议条款。
Offer: expression of willingness to contract on specified terms, made with the intention that it is to become binding as soon as it is accepted (Storer v Manchester City Council).
要约：表示愿意按特定条款签订合同，且意图一经承诺即受约束的意思表示（Storer v Manchester City Council案）。
An invitation to treat is an invitation to negotiate, not an offer (Fisher v Bell; Pharmaceutical Society v Boots; Partridge v Crittenden). Advertisements are generally invitations to treat, unless they amount to a unilateral offer (Carlill v Carbolic Smoke Ball Co).
要约邀请是邀请洽谈，而非要约（Fisher v Bell案；Pharmaceutical Society v Boots案；Partridge v Crittenden案）。广告通常为要约邀请，除非构成单方允诺（Carlill v Carbolic Smoke Ball Co案）。
Acceptance: A final and unqualified expression of assent to the terms of the offer. The general rule is that acceptance must be communicated to the offeror (Entores v Miles Far East Corp). Silence cannot constitute acceptance (Felthouse v Bindley). The postal rule: where acceptance by post is reasonable, acceptance is effective at the moment the letter is posted (Adams v Lindsell), but this rule can be ousted by the offeror.
承诺：对要约条款的最终且无条件的同意表示。一般规则是承诺须传达至要约人（Entores v Miles Far East Corp案）。沉默不能构成承诺（Felthouse v Bindley案）。邮寄规则：若以邮寄承诺为合理方式，则承诺在信件投邮瞬间生效（Adams v Lindsell案），但此规则可被要约人排除。
An offer may be terminated by revocation (must be communicated – Byrne v Van Tienhoven), rejection/counter-offer (Hyde v Wrench), lapse of time, death, or failure of a condition precedent.
要约可因撤销（须传达 – Byrne v Van Tienhoven案）、拒绝/反要约（Hyde v Wrench案）、逾期、死亡或先决条件未成就而终止。
10. Contract Law: Consideration | 合同法：对价
Consideration is the price for which the promise of the other is bought. It must be sufficient but need not be adequate. Rules of consideration are essential to determine enforceability of agreements.
对价是一方购买另一方允诺的代价。对价必须充分但无须相当。对价规则对判断协议的可执行性至关重要。
- Past consideration is not good consideration (Re McArdle); exception: prior request and implied understanding of payment (Lampleigh v Braithwait).
- 过去的对价不是有效对价（Re McArdle案）；例外：事先请求且隐含有偿理解（Lampleigh v Braithwait案）。
- Performance of an existing duty owed to a third party can be good consideration (Scotson v Pegg).
- 履行对第三人的现有义务可构成有效对价（Scotson v Pegg案）。
- Part payment of a debt: the rule in Pinnel’s Case – payment of a smaller sum on the due date is not satisfaction of a larger debt, unless there is some fresh element (e.g., early payment, different place, or addition of a chattel). The equitable doctrine of promissory estoppel can prevent a creditor going back on their promise to accept less where it would be inequitable (High Trees Case; but a "shield, not a sword").
- 部分债务清偿：Pinnel案规则 – 在到期日支付较少金额不构成对较大债务的清偿，除非存在某些新因素（如提前付款、不同地点或附加动产）。衡平法上的允诺禁反言可以阻止债权人在显失公平时违背接受较少清偿的诺言（High Trees案；但仅用作"盾牌"，非"矛"）。
Consideration must move from the promisee, but need not move to the promisor (Tweddle v Atkinson).
对价须由受允诺人提供，但不必向允诺人提供（Tweddle v Atkinson案）。
11. Legal Personnel: Judges, Barristers, Solicitors | 法律职业：法官、大律师、事务律师
England and Wales has a divided legal profession. Barristers have rights of audience in all courts and tend to specialise in advocacy and specialist legal advice. Solicitors provide direct client services, often as the first point of contact, and can appear in lower courts; some now qualify as solicitor advocates with extended rights of audience.
英格兰与威尔士的法律职业分为两支。大律师在所有法院均享有出庭发言权，通常专攻辩护与专家法律意见。事务律师提供直接的客户服务，常作为第一接触点，可在下级法院出庭；部分事务律师现取得事务律师出庭代言人资格，获得扩大的出庭发言权。
Judges: Appointment to judicial office is governed by the Judicial Appointments Commission, based on merit and good character. The hierarchy includes Justices of the Supreme Court, Lord Justices of Appeal, High Court Judges, Circuit Judges, District Judges, and Magistrates (lay justices). Under the Constitutional Reform Act 2005, the Lord Chancellor’s role was reformed, separating the judiciary from the legislature. Superior judges have security of tenure and immunity from suit for their judicial functions.
法官：司法职位的任命由司法任命委员会根据品德才能进行。等级包括最高法院法官、上诉法院大法官、高等法院法官、巡回法官、地区法官及治安法官（非专业法官）。根据2005年宪法改革法，大法官的角色得以改革，司法权与立法权分离。上级法官享有职位保障和司法职务豁免权。
Legal education: Typically, a qualifying law degree (or conversion course) followed by the Bar Training Course (for barristers) and pupillage, or the Solicitors Qualifying Examination (SQE) route and qualifying work experience. The Legal Services Act 2007 liberalised the market, allowing alternative business structures.
法律教育：通常先获得合格法律学位（或转换课程），随后完成律师培训课程（大律师）及实习，或通过事务律师资格考试路线和合格工作经验。2007年法律服务法开放了市场，允许替代性商业结构。
12. Civil Case Tracks & ADR | 民事诉讼途径与替代性争端解决
The Civil Procedure Rules (CPR) introduced a case management system with three tracks, allocating cases based on value and complexity. This ensures proportionate allocation of court resources.
《民事诉讼规则》引入了一套以三个途径为核心的案件管理制度，根据案件标的额和复杂程度分配案件，确保司法资源比例得当。
| Track (途径) | Typical value (典型标的额) | Features (特征) |
| Small claims (小额索赔) | Up to £10,000 (personal injury & housing disrepair: £1,000) | Informal, district judges, limited costs recovery, encourages self-representation. |
| Fast track (快速途径) | £10,000 – £25,000 | Trial within 30 weeks, standard directions, fixed costs, emphasis on streamlined procedure. |
| Multi-track (多轨途径) | Over £25,000 or complex | Flexible case management, tailored directions, possible High Court, broader disclosure. |
Alternative Dispute Resolution (ADR): Methods include negotiation, mediation (neutral third party facilitates agreement – not binding), conciliation (mediator suggests terms), arbitration (binding decision by an arbitrator under the Arbitration Act 1996), and early neutral evaluation. Courts actively encourage ADR through pre-action protocols and costs sanctions for unreasonable refusal to engage in ADR (Halsey v Milton Keynes General NHS Trust). ADR can be cheaper, quicker, and more private, but is not suitable if an injunction or precedent is required.
替代性争端解决方式：方法包括协商、调解（中立第三方促进达成协议 – 不具约束力）、调停（调解员提出条款建议）、仲裁（根据1996年仲裁法由仲裁员作出的具约束力裁决）以及早期中立评估。法院通过诉前议定书和对不合理拒绝参与替代性争端解决施加费用制裁，积极鼓励此类方式（Halsey v Milton Keynes General NHS Trust案）。替代性争端解决更便宜、更快、更私密，但如需禁制令或确立先例则不适合。
