📚 GCSE CIE Law: Formulae and Principles Quick Reference Handbook | GCSE CIE 法律：公式定理速查手册

In legal study, there are no mathematical equations, but there are rigorous rules, tests and principles that function much like formulae: combine the right elements and a legal result follows. This handbook presents core legal 'formulae' across criminal, tort and contract law for GCSE CIE Law students, offering a clear digest of the building blocks required to establish liability, defences or contractual obligations. Each section gives an English explanation followed by a Chinese translation, ensuring you grasp both the legal terminology and its meaning.

法律学习中虽然没有数学公式，但存在着严格的规则、检验标准和原则，它们就像公式一样：只要组合正确的要素，就会产生相应的法律后果。本手册为 GCSE CIE 法律学生梳理了刑法、侵权法和合同法中的核心法律“公式”，清晰地概括了确立责任、抗辩或合同义务所需的基本构件。每小节先以英文解释，再以中文对应，帮助你既掌握法律术语，也理解其含义。

1. The Core Criminal Formula: Actus Reus + Mens Rea = Crime | 核心刑法公式：犯罪行为 + 犯罪心态 = 犯罪

To establish guilt for most criminal offences, the prosecution must prove both the actus reus (guilty act) and the mens rea (guilty mind). The actus reus can be an act, an omission where there is a duty to act, or a state of affairs. The mens rea is the mental element, such as intention, recklessness or negligence, required for the specific offence. Both must coincide in time – the mens rea must exist at the moment the actus reus is committed. For example, in a charge of assault, the actus reus is causing another to apprehend immediate unlawful violence, and the mens rea is intention or recklessness as to causing such apprehension.

要确立大多数刑事罪行的责任，控方必须同时证明犯罪行为（actus reus）和犯罪心态（mens rea）。犯罪行为可以是一种作为、在有作为义务时的不作为，或是一种状态。犯罪心态是具体罪行所要求的心理要素，如故意、轻率或疏忽。两者必须在时间上同时存在——犯罪心态必须存在于犯罪行为发生的瞬间。例如，对袭击罪的指控中，犯罪行为是使他人感知到即将遭受非法暴力，犯罪心态是对造成此种感知的故意或轻率。

2. Murder: Intention to Kill or Cause GBH | 谋杀：故意杀人或造成重伤

The formula for murder is: unlawful killing of a human being under the Queen's peace with malice aforethought. Malice aforethought means an intention to kill or an intention to cause grievous bodily harm (GBH). Intention can be direct or oblique – where death or GBH was a virtually certain consequence of the defendant's actions and the defendant appreciated that fact. The victim must be a reasonable creature in being (a living human). A conviction for murder carries a mandatory life sentence.

谋杀的公式是：在王权和平期内，具有恶意预谋地非法杀人。恶意预谋指具有杀人的故意或造成严重身体伤害的故意。故意可以是直接的，也可以是间接的——当死亡或重伤是被告行为的几乎必然结果，且被告认识到这一事实时。受害者必须是活生生的人。谋杀罪一旦成立，判处强制性终身监禁。

3. Theft: Dishonest Appropriation of Property Belonging to Another with Intention to Permanently Deprive | 盗窃：不诚实地据为己有属于他人的财产，并具有永久剥夺的意图

The Theft Act 1968 defines theft using five elements: appropriation, property, belonging to another, dishonesty, and intention to permanently deprive. Appropriation is any assumption of the rights of an owner. Property includes money and all other property, real or personal, including things in action and other intangible property. The property must belong to another person. Dishonesty is judged by the standards of ordinary decent people, with certain statutory exceptions (e.g., belief in legal right to deprive). The intention to permanently deprive means treating the property as one's own to dispose of regardless of the owner's rights. All five elements must be satisfied simultaneously.

《1968年盗窃法》用五个要素定义了盗窃罪：占用、财产、属于他人、不诚实，以及永久剥夺的意图。占用是指任何行使所有者权利的行为。财产包括金钱和所有其他财产，无论是不动产还是个人财产，包括诉讼中的物和其他无形财产。该财产必须属于他人所有。不诚实按照普通诚实人的标准判断，但存在某些法定的例外情形（如相信有法律上的剥夺权利）。永久剥夺的意图是指不顾所有者的权利，将财产当作自己的财产加以处置。以上五个要素必须同时满足。

4. Involuntary Manslaughter: Unlawful and Dangerous Act or Gross Negligence | 非自愿过失杀人：非法和危险的行为或重大过失

Involuntary manslaughter covers killings where the defendant did not intend to kill or cause GBH, but liability still arises. Two main routes exist: unlawful and dangerous act manslaughter, and gross negligence manslaughter. The formula for the first is: the defendant intentionally committed an unlawful act that was objectively dangerous and caused death. Dangerous means a reasonable person would recognise a risk of some harm. For gross negligence manslaughter, the defendant owed a duty of care to the victim, breached that duty in a way that involved a risk of death, and the breach was so grossly negligent as to amount to a crime.

非自愿过失杀人涵盖被告并无杀人或造成重伤意图但仍需承担责任的杀人行为。主要有两条路径：非法及危险行为过失杀人和重大过失杀人。第一种的公式是：被告故意实施了一个客观上危险的非法行为，并且该行为导致了死亡。危险是指一个理性人会认识到存在某种伤害风险。对于重大过失杀人，被告对被害人负有注意义务，以涉及死亡风险的方式违反了该义务，并且违反程度极其严重，足以构成犯罪。

5. The Duty of Care in Negligence: The Caparo Three-Stage Test | 疏忽侵权中的注意义务：Caparo三步验证

To establish a duty of care in negligence, the courts apply the Caparo test from Caparo Industries v Dickman (1990): (1) was the damage reasonably foreseeable? (2) was there a relationship of proximity between claimant and defendant? (3) is it fair, just and reasonable to impose a duty? All three questions must be answered affirmatively. Additionally, existing precedent for similar situations will heavily influence the court. Once duty is established, breach of duty (falling below the standard of the reasonable person) and causation of damage must be proven to complete the tort.

要在疏忽侵权中确立注意义务，法院适用Caparo Industries v Dickman (1990) 案确立的验证标准：（1）损害是否可合理预见？（2）原告与被告之间是否存在密切关联性？（3）施加义务是否公平、公正且合理？三个问题都必须得到肯定的回答。此外，类似情形下已有的先例将对法院产生重大影响。一旦义务确立，还须证明对该义务的违反（低于理性人的标准）以及因此造成了损害，才能完成侵权责任的认定。

6. Breach of Duty: The Reasonable Person Standard | 义务违反：理性人标准

Once a duty of care exists, the claimant must show that the defendant breached that duty. The test is objective: did the defendant act as a reasonable person would have done in the circumstances? The law does not expect perfection, but ordinary prudence. Special standards apply to professionals (the Bolam test – acting in accordance with a responsible body of professional opinion), learners (they are judged by the standards of a competent qualified person), and children (compared to reasonable children of the same age). Risk factors include the likelihood of harm, the seriousness of potential injury, the social utility of the defendant's conduct, and the cost and practicality of taking precautions.

注意义务一旦存在，原告必须证明被告违反了该义务。判断标准是客观的：被告的行为是否像一个理性人在同等情形下会做的那样？法律并不要求完美，只要求通常的谨慎。对专业人员适用特殊标准（Bolam检验——按照一个负责任的行业意见群体行事），对学习者（按合格从业者的标准判断），以及对儿童（与同龄理性儿童相比较）。风险因素包括伤害发生的可能性、潜在伤害的严重程度、被告行为的社会效用，以及采取预防措施的成本和可行性。

7. Causation in Negligence: Factual and Legal Cause | 疏忽侵权的因果关系：事实原因与法律原因

Even with a duty and breach, liability requires causation. Factual causation uses the 'but for' test: but for the defendant's breach, would the claimant have suffered the loss? If yes, the breach is not the factual cause. Legal causation requires that the damage is not too remote – the kind of damage must be reasonably foreseeable (the Wagon Mound rule). An intervening act (novus actus interveniens) may break the chain of causation if it is a free, voluntary and informed act of a third party or the claimant, or an unforeseeable natural event.

即便有义务和违反，责任还需因果关系。事实因果关系采用“若非”检验标准：若非被告的违反义务行为，原告是否会遭受该损失？如果仍会，则该违反行为并非事实原因。法律因果关系要求损害不能过于遥远——损害的类型必须是可合理预见的（Wagon Mound案规则）。介入行为（新介入行为）如果是第三方或原告自由、自愿且知情的行为，或是不可预见的自然事件，则可以中断因果链条。

8. Vicarious Liability: Employee in the Course of Employment | 替代责任：雇员在雇佣期间的行为

An employer can be vicariously liable for torts committed by an employee. The formula has two stages: (1) was the wrongdoer an employee (a contract of service, not an independent contractor)? (2) was the tort committed in the course of employment? The modern 'close connection' test asks whether the employee's wrongful conduct was so closely connected with his employment that it would be fair and just to hold the employer liable. Acts done during working hours can still be outside the course of employment if they are an independent 'frolic of his own'.

雇主可能为雇员实施的侵权行为承担替代责任。这一公式分为两步：（1）侵权人是否为雇员（存在雇佣合同，而非独立承包商）？（2）侵权行为是否发生在雇佣过程中？现代的“密切关联”检验标准问的是：雇员的不法行为是否与其雇佣关系如此紧密相连，以至于让雇主承担责任是公平公正的。在工作时间内的行为，如果属于独立的“个人嬉戏”，也可能被认为超出雇佣过程。

9. Occupiers' Liability: The Common Duty of Care | 占有人责任：一般注意义务

Under the Occupiers' Liability Act 1957, an occupier of premises owes a common duty of care to all lawful visitors. The duty is to take such care as is reasonable to see that the visitor will be reasonably safe in using the premises for the purpose for which they are invited. The occupier must be prepared for children to be less careful than adults, and may expect that a person in the exercise of a calling will appreciate and guard against special risks. Warnings may discharge the duty if they enable the visitor to be reasonably safe. For trespassers, the 1984 Act imposes a lower duty, arising only if the occupier is aware of the danger and the trespasser, and the risk is one against which the occupier may reasonably be expected to offer protection.

根据《1957年占有人责任法》，场所占有人对所有的合法访客负有一般注意义务。该义务是采取合理注意，确保访客在为受邀请目的而使用场所时获得合理安全。占有人必须预见儿童会比成年人更不小心，且可以期待某一行业的从业者能够认识到并防范特别风险。警告若能使得访客合理安全，即可免除义务。对于侵入者，《1984年法》规定了较低的义务，仅在占有人知晓危险和侵入者的存在，且该风险是合理期待占有人应提供保护的情况下，义务才会产生。

10. The Formation of a Contract: Offer + Acceptance + Consideration + Intention | 合同的成立：要约 + 承诺 + 对价 + 意图

A legally binding contract is formed when one party makes an offer, the other communicates an unconditional acceptance, consideration (something of value) passes between them, and both intend to create legal relations. An offer must be distinguished from an invitation to treat (e.g., display of goods). Acceptance must mirror the offer and be communicated. Consideration must be sufficient but need not be adequate – it is the price for which the promise is bought. The intention to create legal relations is presumed in commercial agreements and rebutted in social and domestic arrangements.

当一方发出要约，另一方传达无条件承诺，双方之间有对价（有价物）交换，并且双方均具有创设法律关系的意图时，一份具有法律约束力的合同便告成立。要约必须与要约邀请（如商品陈列）区别开来。承诺必须与要约完全一致，并传达给要约人。对价必须是充分的，但不必是等值的——它是换取允诺的代价。在商业协议中推定具有创设法律关系的意图，而在社交和家庭安排中这一推定可以被推翻。

11. Defences in Tort: Consent and Illegality | 侵权中的抗辩：同意与非法性

The formula for a successful defence of consent (volenti non fit injuria) is that the claimant freely, with full knowledge, consented to the risk of harm. This can be express (a signed waiver) or implied (a sports participant accepts ordinary risks). The defence of illegality (ex turpi causa) prevents a claimant from recovering compensation if their loss is inextricably linked to their own illegal or immoral act. Courts will refuse to assist when the claim requires reliance on the claimant's own wrongdoing.

成功主张同意抗辩（即自愿者不受损害）的公式是：原告在充分知情的情况下，自愿同意承担伤害风险。同意可以是明示的（签署的免责书）或默示的（体育运动员接受常见风险）。非法性抗辩（基于不体面事由）禁止原告在损失与自身非法或不道德行为密不可分时获得赔偿。当主张必须依赖原告自身的不法行为时，法院将拒绝提供协助。

12. Defences in Criminal Law: Self-Defence and Duress | 刑法抗辩：自卫与胁迫

Self-defence (including defence of another and prevention of crime) requires that the force used was necessary and reasonable in the circumstances as the defendant honestly believed them to be. The defendant's belief does not have to be reasonable, but the more unreasonable it is, the less likely the jury will accept it was honestly held. The force must be proportionate – not grossly disproportionate. Duress by threats is available for many offences (not murder or attempted murder) where the defendant committed the crime because of a threat of death or serious injury to themselves or another, and a reasonable person sharing the defendant's characteristics would have responded in the same way.

自卫（包括防卫他人和预防犯罪）要求所使用的武力，在被告真诚相信的情境下，是必要且合理的。被告的相信不要求是合理的，但越不合理，陪审团就越不可能接受其是真诚持有的。武力必须是相称的——不得严重失当。胁迫抗辩（以威胁为由）适用于许多犯罪（但不包括谋杀或谋杀未遂），条件是被吿是因为遭受到对自己或他人的死亡或严重伤害威胁而实施犯罪，且一个具有被吿相同特征的理性人也会作出同样的反应。
