📚 Year 9 Edexcel Law: Formula & Principles Quick Reference | 九年级爱德思法律：公式与原理速查手册
In law, understanding the building blocks of liability is essential. Unlike maths, where you apply formulas with numbers, law uses 'formulas' made of legal elements that must be proven for a claim or offence to succeed. This quick reference handbook sets out the key principles, tests and element checklists for the topics covered in Year 9 Edexcel Law. Each section presents the legal principle as a memorable formula, followed by clear explanations in both English and Chinese.
在法律中，理解责任的构成要素至关重要。与数学中运用数字公式不同，法律使用的是由法律要素组成的“公式”，这些要素必须得到证明，请求或罪名才能成立。本速查手册列出了九年级爱德思法律课程所涉及的关键原理、检验标准和要素清单。每一节都将法律原则呈现为一个易记的公式，随后用中英双语提供清晰解释。
1. The Crime Formula | 犯罪构成公式
A criminal offence generally requires two things: a guilty act and a guilty mind. This is expressed as: Actus Reus + Mens Rea = Crime (subject to any defence). Actus reus can be an act, an omission (where there is a duty to act), or a state of affairs. Mens rea refers to the mental element, such as intention, recklessness, or negligence. The prosecution must prove both elements beyond reasonable doubt, unless it is a strict liability offence, where no mens rea is needed.
刑事犯罪通常需要两样东西：犯罪行为和犯罪意图。可表示为：犯罪行为 + 犯罪意图 = 犯罪（在不存在抗辩的情况下）。犯罪行为可以是作为、不作为（当存在作为义务时）或特定状态。犯罪意图指主观要素，例如故意、轻率或疏忽。除非是严格责任犯罪（不需要犯罪意图），否则控方必须排除合理怀疑地证明两个要素。
2. Theft (s. 1 Theft Act 1968) | 盗窃罪（1968年《盗窃法》第1条）
Theft is defined as the dishonest appropriation of property belonging to another with the intention of permanently depriving the other of it. The formula is: + Property + Belonging to Another + Dishonesty + Intention to Permanently Deprive = Theft. Even if you later return the item, the intention at the time of appropriation determines liability. The test for dishonesty is the Ivey test: was what the defendant did dishonest according to the standards of ordinary reasonable people?
盗窃罪的定义是，不诚实地将属于他人的财产据为己有，并具有永久剥夺他人对财产的意图。公式为：占用 + 财产 + 属于他人 + 不诚实 + 永久剥夺的意图 = 盗窃罪。即使后来归还了物品，定罪与否取决于占用时的意图。不诚实的检验标准是Ivey标准：根据普通合理人的标准，被告的行为是否不诚实？
3. Assault Formula | 袭击罪公式
An assault occurs when the defendant intentionally or recklessly causes the victim to apprehend immediate unlawful force. No physical contact is needed – the victim must simply believe that harm is about to occur. The formula: Defendant's Act + Victim's Reasonable Apprehension of Immediate Force + Intention or Recklessness = Assault. Words alone can be enough, and silence can also suffice if it creates fear. Conditional threats may also qualify.
当被告故意或轻率地使受害者担心即将遭受非法暴力时，即构成袭击罪。不需要身体接触——受害者只需相信伤害即将发生。公式为：被告的行为 + 受害者对即将到来的暴力的合理恐惧 + 故意或轻率 = 袭击罪。仅凭言语可能就足够，沉默如果造成恐惧也可构成。附条件的威胁也可能符合。
4. Battery Formula | 殴打罪公式
Battery is the actual infliction of unlawful force on another person. Unlike assault, physical contact must occur, even if very slight. The formula: ation of Unlawful Force + Direct or Indirect Contact + Intention or Recklessness = Battery. Touching someone’s clothing or spitting can be battery. Everyday jostling in a crowded place is not battery if it is considered impliedly consented to.
殴打罪是实际对他人施加非法暴力。与袭击罪不同，必须发生身体接触，哪怕非常轻微。公式为：非法暴力的施加 + 直接或间接接触 + 故意或轻率 = 殴打罪。触碰到某人的衣物或吐口水都可能构成殴打。在拥挤场所的日常推搡，如果被视为默示同意的，则不构成殴打。
5. Negligence (Tort) | 过失侵权
Negligence is the tort most commonly used to claim damages for accidental injury. The claimant must prove four elements: Duty of Care + Breach of Duty + Causation + Damage = Negligence. The duty is established using the Caparo three-part test: foreseeability of damage, proximity, and whether it is fair, just and reasonable to impose a duty. Breach is judged by the standard of the reasonable person. Causation requires both factual causation (the 'but for' test) and legal causation (the damage must not be too remote).
过失侵权是最常用于就意外伤害索赔的侵权行为。原告必须证明四个要素：注意义务 + 违反义务 + 因果关系 + 损害 = 过失侵权。注意义务通过Caparo三部分检验法确定：损害的可预见性、关联性，以及施加义务是否公平、公正和合理。违反义务以合理人标准判断。因果关系既需要事实因果关系（“若非”检验），也需要法律因果关系（损害不能过于遥远）。
6. Contract Formation | 合同订立公式
A valid contract requires: Offer + Acceptance + Consideration + Intention to Create Legal Relations = Contract. An offer must be clear and communicated, while acceptance must match the offer exactly (the mirror image rule) and be communicated effectively (though the postal rule can make acceptance effective on posting). Consideration is the value exchanged – something of value in the eyes of the law. In commercial agreements, intention to create legal relations is presumed; in social/domestic arrangements, it is not.
有效合同需要：要约 + 承诺 + 对价 + 建立法律关系的意图 = 合同。要约必须明确并传达，承诺必须完全符合要约（镜像规则）并有效传达（虽然投邮规则可使得承诺在投递时生效）。对价是交换的价值——法律眼中具有价值的东西。在商业协议中，推定具有建立法律关系的意图；在社会/家庭安排中，则不作此推定。
7. Capacity to Contract | 缔约能力公式
Certain persons may lack full capacity to be bound by a contract. The checking sequence is: If (Minor or Mental Incapacity or Intoxication) then Contract may be Voidable or Unenforceable. Minors (under 18) are generally bound only by contracts for necessaries (goods suitable to their station in life and actual needs) and beneficial contracts of service. Adults lacking mental capacity or who are intoxicated may avoid a contract if the other party knew of their incapacity.
某些人可能缺乏受合同完全约束的能力。审核顺序是：如果（未成年人 或 精神上无行为能力 或 醉酒），则合同可能可撤销或不可执行。未成年人（未满18岁）通常只受必需品合同（适合其生活地位和实际需要的物品）和有益的服务合同的约束。缺乏精神能力的成年人或醉酒者，若对方知晓其无能力，可撤销合同。
8. Misrepresentation in Contract | 合同中的虚假陈述
A misrepresentation is a false statement of fact that induces a party to enter a contract. The formula for a claim is: t of is: False Statement of Fact + Addressed to Claimant + Induces Contract + Loss = Actionable Misrepresentation. It can be fraudulent (made knowingly or recklessly), negligent, or innocent. The remedy may be rescission (setting the contract aside) and/or damages, depending on the type.
虚假陈述是指诱使一方订立合同的虚假事实陈述。提出请求的公式为：虚假事实陈述 + 向原告作出 + 诱使订立合同 + 损失 = 可起诉的虚假陈述。它可以是欺诈性的（明知或轻率地做出）、疏忽性的或无意的。根据类型不同，救济可能是撤销合同和/或损害赔偿。
9. Sentencing Factors | 量刑因素速查
When deciding a sentence, courts weigh aggravating and mitigating factors. The sentencing equation: Base Offence Severity + Aggravating Factors – Mitigating Factors = Sentence. Aggravating factors include previous convictions, use of a weapon, or targeting a vulnerable victim. Mitigating factors include a guilty plea (which can reduce the sentence by up to one-third), remorse, or a minor role in the offence. The aim is a proportionate sentence.
法院在决定刑罚时会权衡加重因素和减轻因素。量刑公式：基本罪行严重程度 + 加重因素 – 减轻因素 = 刑罚。加重因素包括前科、使用武器或针对易受伤害的受害者。减轻因素包括认罪（可减少刑期最多三分之一）、悔恨或在犯罪中起次要作用。目标是相称的刑罚。
10. Damages in Tort | 侵权赔偿公式
The basic rule for compensatory damages is to put the claimant back in the position they would have been in had the tort not occurred. ntifiable financial losses) + General Damages (future losses, pain and suffering, loss of amenity). Special damages cover loss of earnings to trial date, medical expenses, and property damage. General damages are assessed by the judge using tariff-like guidelines for personal injury. The aim is full compensation, not punishment.
补偿性损害赔偿的基本规则是使原告恢复到侵权行为未发生时的状态。赔偿 = 特别损害赔偿（可量化的经济损失）+ 一般损害赔偿（未来损失、痛苦和折磨、生活乐趣的丧失）。特别损害赔偿覆盖截至审判日的收入损失、医疗费和财产损害。一般损害赔偿由法官根据类似价目表的指引评估人身伤害。目标是充分补偿，而非惩罚。
11. Quick Reference Table of Key Legal Tests | 关键法律检验标准速查表
Below is a summary of the most frequently used tests across Year 9 topics:
以下是九年级主题中最常用的检验标准汇总：
| Legal Test / 法律检验 | Area / 领域 | Explanation / 说明 |
|---|---|---|
| Ivey Dishonesty Test | Theft / 盗窃 | What was D's actual knowledge/belief? Was the conduct dishonest by the standards of ordinary reasonable people? / 被告的实际认知/信念是什么？根据普通合理人的标准，行为是否不诚实？ |
| Caparo Three-Part Test | Negligence (duty) / 过失（义务） | Foreseeability, proximity, fair/just/reasonable. / 可预见性、关联性、公平/公正/合理。 |
| 'But For' Test | Causation / 因果关系 | But for the defendant's breach, would the damage have occurred? / 若非被告的违反义务，损害会发生吗？ |
| Reasonable Person Standard | Breach of duty / 违反义务 | Did D act as a reasonable person would? / 被告的行为是否像一个合理人那样？ |
| Mirror Image Rule | Contract acceptance / 合同承诺 | Acceptance must match the offer exactly; a counter-offer kills the original offer. / 承诺必须完全匹配要约；反要约消灭原要约。 |
12. Using Formulas in Exam Answers | 在考试答案中运用公式
When tackling problem questions, state the relevant legal 'formula' first, then apply each element to the facts. For instance, for a theft problem, write: 'Under s.1 Theft Act 1968, theft is the dishonest appropriation of property belonging to another with intention to permanently deprive. Here, the defendant appropriated the handbag by taking it. The property belonged to V...' This structured approach shows the examiner you know the law and can apply it precisely.
在处理问题类题目时，先陈述相关的法律“公式”，然后将每个要素应用于事实。例如，对于盗窃问题，写：“根据1968年《盗窃法》第1条，盗窃是指不诚实地将属于他人的财产据为己有，并具有永久剥夺的意图。在此，被告通过拿取占用了手提包。该财产属于受害者V……”这种结构化的答题方法向考官展示你了解法律并能准确运用。
