1. Actus Reus & Mens Rea: The Crime Formula | 犯罪行为与犯罪意图：犯罪公式
Criminal Liability = Actus Reus + Mens Rea − Valid Defence
Almost all crimes require proof of two core elements: the guilty act (actus reus) and the guilty mind (mens rea). The prosecution must show that the defendant voluntarily committed the prohibited act or omission while possessing the relevant mental state, such as intention or recklessness. If a full defence applies, liability is negated even if both elements are present.
几乎所有犯罪都需要证明两个核心要素：犯罪行为（actus reus）和犯罪意图（mens rea）。控方必须证明被告自愿实施了被禁止的行为或不作为，并且具备相关的心理状态，例如故意或轻率。即使两种要素都存在，只要有完整的辩护理由成立，刑事责任也会被否定。
The actus reus can include conduct, consequences, or a state of affairs. Mens rea varies by offence – murder requires intention to kill or cause GBH, while many non-fatal offences accept recklessness. The Latin maxim "actus non facit reum nisi mens sit rea" – the act does not make a person guilty unless the mind is also guilty – underpins this fundamental formula.
犯罪行为可以包括具体行为、造成的后果或者某种状态。犯罪意图因犯罪类型而异——谋杀要求有杀人或造成严重身体伤害的故意，而许多非致命犯罪接受轻率的主观心态。拉丁法律格言“actus non facit reum nisi mens sit rea”（行为本身不构成犯罪，除非具有犯罪心理）正是这一基本公式的基石。
2. Causation: The 'But For' and Legal Cause Tests | 因果关系：“若无则不”与法律原因检验
Causation = Factual Causation (But For) + Legal Causation (Operating & Substantial)
When a crime requires a result (e.g., murder, ABH), the prosecution must prove that the defendant's act both factually and legally caused the harm. Factual causation is established using the "but for" test: but for the defendant's conduct, would the result have occurred? If the answer is no, factual causation is satisfied (R v White).
当犯罪要求造成特定结果时（如谋杀、实际身体伤害），控方必须证明被告的行为既在事实上又在法律上造成了伤害。事实因果关系通过“若无则不”检验确定：如果没有被告的行为，结果还会发生吗？如果答案是否定的，事实因果关系即成立（R v White案）。
Legal causation requires that the defendant's act was a more than minimal cause (substantial) and remained the 'operating' cause. A new intervening act (novus actus interveniens) may break the chain of causation, relieving the defendant of liability – but only if it is unforeseeable. The thin skull rule says a defendant must take the victim as they find them (R v Blaue).
法律因果关系要求被告的行为既是实质性的（不仅仅是微小的原因），而且是持续在起作用的“原因”。一个新的介入行为（novus actus interveniens）可能打断因果关系链条，使被告不再承担责任——但这只在介入行为不可预见时才会发生。“薄头骨”规则规定，被告必须接受受害人的现有身体状况（R v Blaue案）。
3. Non-Fatal Offences: Assault, Battery, ABH, GBH | 非致命犯罪：企图伤害、殴打、实际身体伤害与严重身体伤害
Non-Fatal Offence Grid: Actus Reus + Mens Rea (Intention / Recklessness)
The four main non-fatal offences form a ladder of severity. Assault requires causing the victim to apprehend immediate unlawful force (R v Ireland – silent phone calls). Battery requires the actual infliction of unlawful force, however slight. Both are summary offences with relatively low maximum sentences.
四种主要的非致命犯罪构成一个严重程度由低到高的阶梯。企图伤害（Assault）要求致使受害人担心即将遭受非法暴力（R v Ireland案——沉默的电话）。殴打（Battery）要求实际施加非法暴力，无论多么轻微。两者都属于简易罪，最高刑期相对较低。
Assault occasioning actual bodily harm (ABH) under s.47 OAPA 1861 requires proof of assault or battery that causes "actual bodily harm". The harm can be physical or psychiatric (R v Chan-Fook). The mens rea is intention or recklessness as to the assault/battery – no need to intend the harm. GBH under s.20 (wounding/inflicting) requires "really serious harm" and mens rea of some foresight of physical harm. The most serious, s.18 GBH with intent, demands proof of intention to cause GBH or resist/prevent arrest.
根据1861年《侵害人身罪法》第47条，造成实际身体伤害的企图伤害罪（ABH）要求证明存在企图伤害或殴打行为，并导致“实际身体伤害”。伤害可以是对身体或精神的（R v Chan-Fook案）。犯罪意图是对企图伤害或殴打行为存在故意或轻率——无需意图造成该伤害。第20条下的重伤罪（伤害/造成）要求“真正严重的伤害”，犯罪意图是对身体伤害有一定预见。最严重的第18条故意重伤罪则要求证明有造成严重身体伤害的故意，或者为抗拒或阻止合法逮捕而故意造成伤害。
4. Property Offences: Theft and Robbery | 财产犯罪：盗窃与抢劫
onest Appropriation of Property Belonging to Another with Intention to Permanently Deprive
Under the Theft Act 1968, theft is defined by five elements. The actus reus is appropriation (any assumption of the owner's rights), of property (including money, tangible items, and intangible property), belonging to another. The mens rea is dishonesty and intention permanently to deprive.
根据1968年《盗窃法》，盗窃罪由五个要素界定。犯罪行为是“侵占”（任何行使所有者权利的行为）、侵占的是“财产”（包括金钱、有体物和无体财产）、且财产“属于他人”。犯罪意图包括“不诚实”和“永久性剥夺的意图”。
For dishonesty, the test established in Ivey v Genting Casinos (2017) looks first at the defendant's actual state of knowledge or belief as to the facts, and then asks whether the conduct was dishonest by the standards of ordinary decent people. Previously, the two-stage Ghosh test was used, but Ivey is now the authority. Robbery is theft aggravated by the use or threat of force immediately before or at the time of stealing, to put the victim in fear (s.8 Theft Act 1968).
就“不诚实”而言，Ivey v Genting Casinos (2017)案确立的检验标准首先考察被告对事实的实际认识或信念状态，然后询问根据普通正直人士的标准该行为是否不诚实。此前曾使用两阶段的Ghosh检验标准，但Ivey案现在是权威判例。抢劫罪是盗窃罪的加重形态，要求在盗窃即将发生前或盗窃时使用暴力，或威胁使用暴力以使受害人产生恐惧（1968年《盗窃法》第8条）。
5. General Defences in Criminal Law | 刑法中的一般辩护理由
No Liability = Defence Successful (Self-Defence, Duress, Insanity, Automatism)
A defendant may avoid conviction even if the elements of an offence are proved by raising a full defence. Self-defence (and defence of another/prevention of crime) allows reasonable force in the circumstances genuinely believed by the defendant (R v Gladstone Williams). The force must be necessary and proportionate.
即使犯罪要素得到证明，被告也可能通过提出完全辩护理由避免定罪。自我防卫（以及防卫他人/预防犯罪）允许在被告真诚相信的情况下使用合理武力（R v Gladstone Williams案）。武力必须是必要的且相称的。
Duress of threats applies where the defendant commits a crime because they were threatened with death or serious injury and a reasonable person would have acted similarly. Duress is not a defence to murder (R v Howe). The defence of insanity (M'Naghten Rules) requires proof of a defect of reason from a disease of the mind, so that the defendant did not know the nature and quality of the act or that it was wrong. Automatism covers involuntary acts caused by an external factor, such as a physical reflex or hypoglycaemia.
受胁迫的紧急避险适用于被告因受到死亡或严重伤害的威胁而犯罪，并且一个理性人在同样情况下也会如此行为的情况。胁迫不能作为谋杀的辩护理由（R v Howe案）。精神失常辩护（M'Naghten规则）要求证明被告因精神疾病导致理性缺损，以致于不知道行为的性质和错误性。自动症则涵盖由外部因素引起的非自愿行为，如生理反射或低血糖状态。
6. Tort of Negligence: The Neighbour Principle | 过失侵权：邻人原则
Negligence = Duty of Care + Breach of Duty + Damage (Causation & Remoteness)
In civil law, a person harmed by another's carelessness may claim damages under the tort of negligence. The claimant must prove three core elements. First, the defendant owed them a duty of care. The modern test comes from Caparo v Dickman: foreseeability of damage, proximity, and whether it is fair, just and reasonable to impose a duty.
在民法中，因他人疏忽而遭受损害的人可以根据过失侵权索赔损害赔偿。索赔人必须证明三个核心要素。首先，被告对他们负有注意义务。现代检验标准源自Caparo v Dickman案：损害的可预见性、亲近关系，以及施加注意义务是否公平、公正和合理。
Second, the defendant breached that duty by failing to act as a reasonable person would. The standard is objective, but factors like the magnitude of risk, cost of precautions, and social utility of the activity are weighed (Bolton v Stone). Third, the breach must cause the damage: factual causation (but for) and legal causation (remoteness – the damage must not be too remote a consequence). The Wagon Mound test asks whether the type of damage was reasonably foreseeable.
其次，被告因未能像一个理性人那样行事而违反了该注意义务。判断标准是客观的，但需要权衡风险的大小、采取预防措施的成本以及活动的社会效用等因素（Bolton v Stone案）。第三，违反义务必须导致了损害：事实因果关系（若无则不）和法律因果关系（损害的遥远性——损害不得是过于遥远的后果）。Wagon Mound案检验标准询问的是损害的类型是否可合理预见。
7. Contract Law: Offer, Acceptance, and Consideration | 合同法：要约、承诺与对价
inding Contract = Offer + Acceptance + Consideration + Intention to Create Legal Relations
A contract is a legally enforceable agreement. The first requirement is a clear offer – an expression of willingness to contract on specified terms, made with the intention that it shall become binding on acceptance. An invitation to treat, such as goods on a shelf (Pharmaceutical Society v Boots), is not an offer but an invitation for the customer to make an offer.
合同是具有法律强制执行力的协议。第一个要件是明确的要约——即基于特定条款订立合同的意愿表示，并意图一经承诺即受其约束。要约邀请，例如货架上陈列的商品（Pharmaceutical Society v Boots案），并非要约，而是邀请顾客发出要约。
Acceptance must be communicated and unconditional, mirroring the terms of the offer. The postal rule states that acceptance by post is effective upon posting (Adams v Lindsell), though modern electronic communications are governed by different rules. Consideration is the 'price' of the promise – something of value moving from the promisee, though it need not be adequate (Chappell & Co v Nestle). The intention to create legal relations is presumed in commercial agreements and denied in social/domestic settings unless rebutted.
承诺必须被传达且无条件，并就要约条款达成一致。邮寄规则规定，通过邮寄方式作出的承诺在投邮时即生效（Adams v Lindsell案），尽管现代电子通信适用不同的规则。对价是允诺的“价格”——由受允诺人提供的具有价值之物，但不要求对价是等价的（Chappell & Co v Nestle案）。创设法律关系的意图在商业协议中推定存在，而在社交或家庭场合中推定不存在，除非有相反证据推翻。
8. The Doctrine of Precedent and Statutory Interpretation | 先例原则与法律解释
Precedent = Ratio Decidendi (Binding) + Obiter Dicta (Persuasive)
The English legal system operates on the doctrine of judicial precedent (stare decisis). When a court decides a case, its legal reasoning produces a ratio decidendi – the legal principle necessary for the decision – which binds future lower courts in similar cases. Any remarks 'by the way' (obiter dicta) are not binding but may be highly persuasive (as in Hedley Byrne v Heller).
英国法律体系遵循司法先例原则（遵循先例）。法院在裁决案件时，其法律推理会产生“判决理由”（ratio decidendi）——对判决必要的法律原则——对未来类似案件中下级法院具有约束力。任何附带意见（obiter dicta）不具有约束力，但可能具有很强的说服力（如Hedley Byrne v Heller案）。
Alongside precedent, judges often need to interpret statutes. The four main rules are: the literal rule (words given their plain, ordinary meaning – R v Harris); the golden rule (avoiding absurd results by choosing between possible meanings – Adler v George); the mischief rule (examining the gap in the common law the statute was meant to remedy – Smith v Hughes); and the purposive approach (looking at the overall purpose of the Act – Pepper v Hart).
除了先例外，法官经常需要解释制定法。四种主要规则是：字面规则（按照词语的平实普通含义解释——R v Harris案）；黄金规则（在可能的含义中进行选择以避免荒谬结果——Adler v George案）；弊害规则（考察该制定法旨在弥补的普通法漏洞——Smith v Hughes案）；以及目的性解释方法（考察该立法的整体目的——Pepper v Hart案）。

10. Legal Maxims and Latin Terms | 法律格言与拉丁语速查
Many legal principles are encapsulated in short Latin phrases that function like 'formula names'. Knowing them will make your essays more precise and academic. Below are the most frequently encountered maxims for Eduqas law students.
许多法律原则被浓缩成简洁的拉丁短语，就像“公式名称”一样。掌握它们能让你的论文更精确、更具学术性。以下是 Eduqas 法律学生最常遇到的格言。
- Actus non facit reum nisi mens sit rea: The act is not guilty unless the mind is guilty.
- Novus actus interveniens: A new intervening act breaking the chain of causation.
- Stare decisis: To stand by things decided – the foundation of judicial precedent.
- Ratio decidendi: The reason for the decision; the binding part of a judgment.
- Obiter dicta: Things said by the way; persuasive but not binding.
- Mens rea: Guilty mind; the mental element of a crime.
- Actus reus: The guilty act or conduct element of a crime.
- Volenti non fit injuria: To a willing person, no injury is done – a defence in tort.
Memorising these maxims allows you to name the legal concept instantly when you spot an issue in an exam problem. For instance, invoking novus actus interveniens when a third party's unforeseeable conduct breaks the chain of causation adds sophistication to your analysis.
记住这些格言，你就能在考试中发现问题时立刻说出法律概念的名称。例如，当第三方的不可预见行为打断了因果关系链时，引用novus actus interveniens可以为你的分析增添深度。
