📚 Year 8 Edexcel Law: Formulas and Principles Quick Reference | Year 8 Edexcel 法律：公式定理速查手册
This quick reference guide breaks down the key legal principles you need for Year 8 Edexcel Law into simple 'formulas'. By remembering these equations, you can easily recall the essential elements of crimes, defences, and legal concepts that form the foundation of criminal law.
本速查手册将Year 8 Edexcel法律课程的核心法律原则分解为简单的“公式”。通过记住这些等式，你可以轻松回忆犯罪、抗辩理由的基本要素以及构成刑法基础的法律概念。
1. The Crime Formula | 犯罪公式
In criminal law, to establish guilt, the prosecution must prove beyond reasonable doubt that the defendant committed a guilty act (actus reus) with a guilty mind (mens rea) and that no defence applies.
在刑法中，要确定有罪，控方必须排除合理怀疑地证明被告人实施了犯罪行为（actus reus）且具有犯罪意图（mens rea），并且没有有效的抗辩理由。
Crime = Actus Reus + Mens Rea − Defence
Actus reus means the 'guilty act'. It can be a positive action (e.g., hitting someone) or, in some cases, a failure to act (omission) where there is a legal duty.
犯罪行为（actus reus）意为“有罪的行为”。它可以是积极行为（例如，殴打他人），或在某些情况下，当存在法律义务时的不作为（omission）。
Mens rea means the 'guilty mind'. The level of mens rea required varies by crime: intention, recklessness, or sometimes negligence.
犯罪意图（mens rea）意为“有罪的心理”。犯罪意图的要求因罪行而异：可能是故意、轻率，有时是疏忽。
2. Actus Reus Elements | 犯罪行为要素
Actus reus is not just the act itself; for many crimes it includes three components: conduct, circumstances, and consequences.
犯罪行为不仅仅是行为本身；对许多犯罪而言，它包括三个组成部分：行为、情节和后果。
Actus Reus = Conduct + Circumstances + Consequence (where relevant)
Conduct: the physical movement or omission. Circumstances: the surrounding facts that make the act criminal (e.g., taking property 'belonging to another' in theft). Consequence: the result caused by the conduct (e.g., death in murder).
行为：身体动作或不作为。情节：使该行为构成犯罪的周围事实（例如，盗窃中“属于他人的”财产）。后果：行为所导致的结果（例如，谋杀中的死亡）。
For a result crime like murder, causation must be proved. The prosecution must show both factual causation (the 'but for' test) and legal causation (the defendant's act was a substantial and operating cause of the result).
对于谋杀等结果犯，必须证明因果关系。控方必须证明事实因果关系（“若无则不”检验）和法律因果关系（被告的行为是结果的实质性和有效原因）。
3. Mens Rea Types | 犯罪意图类型
Mens rea is the mental element of an offence. The key levels are intention, recklessness, and sometimes negligence. Remember the hierarchy.
犯罪意图是罪行的心理要素。主要层次为故意、轻率和有时是疏忽。记住这个层级。
| Mens Rea Type | 犯罪意图类型 | Definition | 定义 |
|---|---|---|---|
| Direct Intention | 直接故意 | Defendant aims to bring about a particular consequence. | 被告旨在实现特定后果。 |
| Oblique Intention | 间接故意 | Consequence is virtually certain and defendant foresaw it as virtually certain. | 后果几乎是确定的，且被告预见其为几乎确定。 |
| Recklessness | 轻率 | Defendant foresaw a risk of the consequence and unreasonably took that risk. | 被告预见到风险，且不合理地冒了这个风险。 |
Some lesser offences require only negligence, meaning the defendant's conduct fell below the standard of a reasonable person, even without awareness of the risk.
一些较轻的罪行仅要求疏忽，即被告的行为低于合理人的标准，即使没有意识到风险。
4. Causation Formula | 因果关系公式
In result crimes, the defendant's act must cause the prohibited consequence. The formula has two parts.
在结果犯中，被告的行为必须造成被禁止的后果。该公式有两部分。
Causation = Factual Causation + Legal Causation
Factual causation uses the 'but for' test: but for the defendant's conduct, would the result have happened? If the answer is 'no', factual causation is established.
事实因果关系运用“若无则不”检验：若无被告的行为，结果会发生吗？如果答案是“否”，则事实因果关系成立。
Legal causation requires that the defendant's act was a substantial and operating cause of the result. There must be no novus actus interveniens (new intervening act) that breaks the chain of causation.
法律因果关系要求被告的行为是结果的实质性和有效原因。不得有新介入行为（novus actus interveniens）打破因果关系链。
5. Theft Formula | 盗窃公式
Theft is defined in s.1 of the Theft Act 1968. It can be broken down into five elements that must all be present.
盗窃由《1968年盗窃法》第1条定义。它可以分解为必须全部满足的五个要素。
shonest Appropriation + Property + Belonging to Another + Intention to Permanently Deprive
Appropriation: assuming the rights of the owner (e.g., taking, selling, destroying). Must be dishonest according to the standards of ordinary decent people, and the defendant must realize it was dishonest by those standards (Ghosh test).
侵占：行使所有者的权利（如取走、出售、毁坏）。必须按照普通正派人的标准不诚实，且被告必须意识到按照那些标准是不诚实的（Ghosh检验标准）。
Property includes money, personal items, intangible property, but not wild plants or knowledge. Belonging to another means the property is owned, possessed, or controlled by someone else. Intention to permanently deprive: must intend to treat the property as their own to dispose of regardless of the owner's rights.
财产包括金钱、个人物品、无形财产，但不包括野生植物或知识。属于他人是指财产由他人拥有、占有或控制。永久性剥夺
