1. What Is Law? | 什么是法律？
Law is a system of rules created and enforced by the state to regulate behaviour within society. Its primary purposes are to maintain order, protect individual rights, resolve disputes, and deliver justice.
法律是由国家制定并强制实施的一套规则体系，用于规范社会行为。其主要目的是维护秩序、保护个人权利、解决纠纷和伸张正义。
Fundamental formula: A valid law must have a recognised source (Parliament or courts) and be enforceable by state institutions such as the police and courts.
基本公式： 一项有效的法律必须具有公认的来源（议会或法院），并能由国家机构（如警察和法院）强制执行。
2. Sources of Law: Parliament and the Courts | 法律渊源：议会与法院
English law comes from two main sources. Statute law is made by Parliament in the form of Acts. Common law is developed by judges through decisions in individual cases, which then become precedents for future courts.
英国法律有两个主要来源。成文法由议会以法令形式制定。普通法由法官在个案判决中发展而来，这些判决成为未来法院审判的先例。
The relationship can be expressed by the 'source equation':
English Law = Statute Law (Acts of Parliament) + Common Law (Judicial Precedent)
这种关系可以用“渊源等式”来表示：
英国法律 = 成文法（议会法令） + 普通法（司法先例）
Acts of Parliament are the supreme form of law; if statute and common law conflict, statute prevails under the doctrine of parliamentary sovereignty.
议会法令是最高的法律形式；如果成文法与普通法产生冲突，根据议会主权原则，成文法优先。
3. The Criminal Law Equation: Actus Reus + Mens Rea | 刑法等式：犯罪行为 + 犯罪意图
To establish most criminal offences, the prosecution must prove two essential elements beyond a reasonable doubt. The physical element, or guilty act, is called actus reus. The mental element, or guilty mind, is called mens rea.
要证明大多数刑事犯罪，控方必须在排除合理怀疑的程度上证明两个基本要素。物理要素，即犯罪行为，称为actus reus；心理要素，即犯罪意图，称为mens rea。
Criminal Offence = Actus Reus + Mens Rea
刑事犯罪 = 犯罪行为 + 犯罪意图
For example, in a charge of theft, the actus reus is the dishonest appropriation of property belonging to another. The mens rea is the intention to permanently deprive the owner of it. If either element is missing, the defendant cannot be convicted of that offence.
例如，在盗窃指控中，犯罪行为是不诚实地占有他人财产，犯罪意图是永久剥夺物主财产的意图。如果缺少其中任何一个要素，被告就不能被判定犯有该罪行。
4. Strict Liability: Crimes Without Mens Rea | 严格责任：无需犯罪意图的犯罪
Some offences do not require proof of mens rea for at least part of the act. These are known as strict liability offences, where doing the prohibited act alone is enough to establish guilt, regardless of intention.
有些犯罪至少对部分行为不要求证明犯罪意图。这类犯罪被称为严格责任犯罪，只要实施了被禁止的行为就足以定罪，无论意图如何。
Strict Liability Offence = Actus Reus (no Mens Rea needed)
严格责任犯罪 = 犯罪行为（无需犯罪意图）
Common examples include many regulatory offences, such as selling alcohol to a person under 18, or speeding. The law places a duty on individuals to ensure they comply, making it easier to protect the public.
常见的例子包括许多监管性犯罪，例如向未满18岁者出售酒精饮品或超速驾驶。法律要求个人有责任确保合规，从而更有效地保护公众。
5. Causation in Criminal Law | 刑法中的因果关系
When a crime requires a specific result, such as murder or grievous bodily harm, the prosecution must prove that the defendant's act was both the factual and legal cause of that result. This is the causation requirement.
当犯罪要求特定结果时，例如谋杀或严重身体伤害，控方必须证明被告的行为既是该结果的事实原因，也是法律原因。这就是因果关系要件。
Liability = Actus Reus + Causation (Factual & Legal) + Mens Rea
责任 = 犯罪行为 + 因果关系（事实与法律） + 犯罪意图
Factual causation uses the 'but for' test: but for the defendant's actions, would the harm have occurred? Legal causation asks whether the defendant's act was a substantial and operating cause of the harm.
事实因果关系采用“若无则不”检验：如果没有被告的行为，损害会发生吗？法律因果关系则考察被告的行为是否为损害的重大且有效的原因。
6. Tort Law: The Negligence Formula | 侵权法：过失侵权公式
In civil law, the tort of negligence allows a claimant to seek compensation when they have suffered injury or loss due to another's carelessness. Three core elements must be proved on the balance of probabilities.
在民法中，过失侵权允许原告在因他人粗心大意而遭受伤害或损失时寻求赔偿。必须按盖然性权衡证明三个核心要素。
Negligence = Duty of Care + Breach of Duty + Damage (Causation)
过失 = 注意义务 + 违反义务 + 损害（因果关系）
First, the defendant must owe a duty of care to the claimant. The 'neighbour principle' from Donoghue v Stevenson (1932) states that you must take reasonable care to avoid acts or omissions which you can reasonably foresee would injure your neighbour.
首先，被告必须对原告负有注意义务。Donoghue v Stevenson (1932) 案中的“邻人原则”指出，你必须采取合理注意，避免可以合理预见会伤害邻人的作为或不作为。
Second, the defendant must breach that duty by falling below the standard of a reasonable person. Third, the breach must cause the damage, both factually and legally.
其次，被告的行为必须低于合理人的标准，从而违反该义务。第三，这种违反必须导致损害，包括事实和法律上的因果关系。
7. Contract Law: The Agreement Formula | 合同法：协议公式
In contract law, a binding agreement is formed when one party makes a definite offer and the other party communicates an unconditional acceptance. This meeting of minds is the foundation of every contract.
在合同法中，当一方发出确定的要约，另一方传达无条件的承诺时，便形成了有约束力的协议。这种合意是每一份合同的基础。
Contract = Offer + Acceptance + Consideration + Intention to Create Legal Relations
合同 = 要约 + 承诺 + 对价 + 建立法律关系的意图
An offer can be made to one person or to the whole world, as in Carlill v Carbolic Smoke Ball Co (1893). Acceptance must mirror the offer exactly; otherwise, it is a counter-offer which destroys the original offer. Consideration means something of value must be exchanged, and both parties must intend to be legally bound.
要约可以向一人或向全世界发出，如Carlill v Carbolic Smoke Ball Co (1893) 案所示。承诺必须与要约完全对应；否则即为反要约，使原要约失效。对价指必须交换有价值之物，且双方均有意受法律约束。
8. The Court Hierarchy | 法院等级体系
The English court system is structured in a clear hierarchy. Understanding this structure helps to see how appeals work and which courts create binding precedents for others.
英国法院体系具有清晰的等级结构。理解这一结构有助于了解上诉如何运作，以及哪些法院为其他法院创设有约束力的先例。
Hierarchy of courts (criminal and civil combined in simplified form):
简化后的法院等级（刑事与民事合并）：
| Level | Courts |
|---|---|
| Supreme (highest) | Supreme Court of the United Kingdom |
| Senior appellate | Court of Appeal (Civil & Criminal Divisions) |
| Middle tier | High Court (Queen's Bench, Chancery, Family); Crown Court (criminal trials) |
| Lower tier | Magistrates' Court (criminal/family), County Court (civil), Tribunals |
Courts are bound by decisions of higher courts in the same hierarchy under the doctrine of stare decisis (let the decision stand). This ensures consistency and fairness in the common law.
根据“遵循先例”原则，同级或下级法院受上级法院判决的约束。这确保了普通法的一致性和公平性。
9. Judicial Precedent: Ratio Decidendi and Obiter Dicta | 司法先例：判决理由与附带意见
Not every part of a judge's decision is binding on future courts. Only the legal principle necessary for reaching the outcome is binding; this is the ratio decidendi. Other remarks are obiter dicta (things said by the way) and are persuasive only.
法官判决中并非所有部分都对未来的法院具有约束力。只有为达成判决结果所必需的法律原则才具有约束力，这被称为“判决理由”。其他评论是“附带意见”，仅具说服力。
Binding Precedent = Ratio Decidendi (the legal reasoning core)
约束性先例 = 判决理由（法律推理核心）
When judges wish to depart from an inconvenient precedent, they may use the power to distinguish cases by finding a material difference in facts, or higher courts can overrule a lower court's decision. The Supreme Court can depart from its own past decisions under the 1966 Practice Statement.
当法官希望偏离不便适用的先例时，可以通过找出事实上的重大差异来“区分案件”，或者上级法院可以推翻下级法院的判决。根据1966年实务声明，最高法院可以偏离自己过去的决定。
10. The Role of the Jury in Criminal Trials | 陪审团在刑事审判中的作用
In the Crown Court, serious criminal cases are tried by a judge and a jury of 12 members of the public. The jury's job is to decide the facts and reach a verdict of guilty or not guilty based on the evidence presented.
在刑事法院，严重的刑事案件由一名法官和12名公众组成的陪审团审理。陪审团的工作是根据呈堂的证据判定事实，作出有罪或无罪的裁决。
Trial = Judge (law) + Jury (facts) → Verdict
审判 = 法官（法律） + 陪审团（事实） → 裁决
The judge directs the jury on the relevant law and sums up the evidence, but the jury's verdict must be unanimous or, in some circumstances, a majority of at least 10 out of 12. Juries are vital in placing community values at the heart of justice.
法官就相关法律对陪审团作出指示并总结证据，但陪审团的裁决必须一致，或在某些情况下至少达到10比2的多数。陪审团在将社区价值观置于司法核心方面至关重要。
11. Age of Criminal Responsibility | 刑事责任年龄
Not everyone can be held liable for a criminal offence. The law sets a minimum age below which a child is considered incapable of committing a crime, regardless of the act. In England and Wales, the age of criminal responsibility is 10 years old.
并非所有人都能被追究刑事责任。法律规定了最低年龄，低于该年龄的儿童被认为不具备犯罪能力，无论其行为如何。在英格兰和威尔士，刑事责任年龄为10岁。
If Age < 10 → Incapable of Crime (doli incapax)
如果年龄 < 10 → 无犯罪能力（不能为恶）
Before the Crime and Disorder Act 1998, there was a rebuttable presumption that children aged 10 to 13 were doli incapax (incapable of evil), but this was abolished. Now, those aged 10 and over are treated as potentially fully criminally responsible, though they are tried in the youth court for most offences.
在1998年《犯罪与骚乱法》之前，有一个可反驳的推定，即10至13岁的儿童“不能为恶”，但该推定已被废除。现在，10岁及以上者被视为可能负有完全刑事责任，但大多数罪行在少年法庭审理。
12. Fundamental Legal Maxims | 基本法律格言
Several Latin maxims act as guiding formulas across many areas of law. They express foundational principles of fairness, proof and justice that underpin legal reasoning.
若干拉丁格言的作用如同贯穿许多法律领域的指导公式。它们表达了公平、证明和正义的根本原则，支撑着法律推理。
- Ei incumbit probatio qui dicit, non qui negat - The burden of proof lies upon him who affirms, not upon him who denies. (The prosecution or claimant must prove their case.)
- 举证责任在于主张者，而非否认者。（控方或原告必须证明其案件。）
- Ignorantia juris non excusat - Ignorance of the law is no excuse. Every person is presumed to know the law.
- 不知法不免责。每个人都被推定知晓法律。
- Nemo dat quod non habet - No one can give what they do not have. (You cannot transfer a better title than you possess.)
- 无人能给出自己没有之物。（你不能转让比你拥有的更优的所有权。）
- Audi alteram partem - Hear the other side. Both parties must be given a fair opportunity to present their case.
- 听取另一方意见。双方都必须获得公平机会陈述己方案情。
These maxims help lawyers and judges ensure that procedure and substance remain aligned with the rule of law.
这些格言有助于律师和法官确保程序与实体内容符合法治。
