本速查手册汇总了剑桥IGCSE法律大纲中的核心法律原则与规则。法律并非依赖数学公式，而是通过结构化的法律检验标准、格言和定义来运作。每个条目都以易记的“公式”或框架呈现，帮助您精准、高效地回溯刑法、侵权法、合同法以及人权法中的关键概念组成要素。
1. The Legal System: Fundamental Maxims | 法律体系：根本格言
Law operates on foundational maxims that guide judicial reasoning and the application of justice. These Latin phrases encapsulate centuries of legal thought and are frequently referenced to underpin arguments in court.
法律运作依赖根本性格言，这些格言指导着司法推理与正义的实现。这些拉丁短语凝聚了数百年的法律思想精华，常被引用来支撑法庭辩论。
| Maxim / 格言 | Meaning / 含义 |
|---|---|
| Actus non facit reum nisi mens sit rea | The act is not guilty unless the mind is guilty. / 行为本身不构成犯罪，除非具有犯罪心理。 |
| Ignorantia juris non excusat | Ignorance of the law is no excuse. / 不知法不免责。 |
| Stare decisis | To stand by things decided; the doctrine of precedent. / 遵循先例；先例原则。 |
| Obiter dicta | Things said by the way; non-binding judicial remarks. / 附带意见；不具约束力的法官附带评论。 |
| Ratio decidendi | The reason for the decision; the binding part of a judgment. / 判决理由；判决中具有约束力的部分。 |
2. Criminal Liability Formula | 刑事责任构成公式
To secure a conviction in criminal law, the prosecution must prove beyond reasonable doubt the coexistence of the guilty act and the guilty mind, alongside the absence of any valid defence. This dual requirement ensures that only blameworthy conduct is punished.
在刑法中，要成功定罪，控方必须排除合理怀疑地证明犯罪行为与犯罪心理同时存在，且不存在任何有效抗辩。这一双重要件确保只有应受谴责的行为才会受到惩罚。
Crime = Actus Reus (AR) + Mens Rea (MR) + (− Defences)
犯罪 = 犯罪行为 (AR) + 犯罪心理 (MR) + (− 抗辩事由)
| Element / 要素 | Description / 描述 |
|---|---|
| Actus Reus (AR) | The guilty act, omission (where a duty exists), or state of affairs. Must be voluntary. / 犯罪行为、不作为（存在义务时）或特定状态。必须出于自愿。 |
| Mens Rea (MR) | The guilty mind: intention (direct or oblique), recklessness (Cunningham subjective test), or negligence. / 犯罪心理：意图（直接或间接）、轻率（Cunningham主观标准）或过失。 |
| Causation | Factual: 'But for' test (White). Legal: Operating and substantial cause, more than minimal (Smith), no novus actus interveniens. / 事实因果：“若非”检验（White案）。法律因果：持续且实质的原因，超越微量（Smith案），无新介入行为。 |
3. Mens Rea Sub-Types | 犯罪心理细分类型
The precise level of fault required varies by offence. Distinguishing between direct intention, oblique intention, and recklessness is critical for accurately applying the law to facts, as each carries a different threshold of culpability.
不同罪行要求的过错程度各有不同。区分直接意图、间接意图和轻率对于将法律准确适用于事实至关重要，因为每一种都对应不同的罪责门槛。
| Mental State / 心理状态 | Definition / Test | 定义 / 标准 |
|---|---|
| Direct Intention / 直接意图 | D's aim, purpose, or desire to bring about a result (Mohan). / 被告的目标、目的或期望达成某一结果（Mohan案）。 |
| Oblique Intention / 间接意图 | (i) Result was a virtually certain consequence of D's act, and (ii) D appreciated this was so (Woollin). / (i) 结果是被告行为几乎必然发生的后果，且 (ii) 被告意识到这一点（Woollin案）。 |
| Recklessness / 轻率 | D foresaw a risk of the prohibited consequence occurring and unreasonably took that risk (Cunningham). / 被告预见会发生被禁止后果的风险，且不合理地仍然冒此风险（Cunningham案）。 |
| Transferred Malice | MR directed at one person can transfer to the actual unintended victim for the same type of offence (Latimer). / 针对一人的犯意可转移至同一类罪行的实际非预期受害人（Latimer案）。 |
4. Non-Fatal Offences Structure | 非致命侵害人身罪框架
Non-fatal offences against the person are hierarchically structured based on the level of harm caused and the associated mens rea. The ladder rises from simple assault to causing grievous bodily harm with intent, and precisely matching the actus reus and mens rea is vital.
非致命侵害人身罪依据造成的伤害程度及相应的犯罪心理形成层级结构。从简单的殴打罪到故意造成严重身体伤害罪，这一阶梯式上升；精准匹配犯罪行为与犯罪心理至关重要。
| Offence / 罪行 | Actus Reus (AR) | Mens Rea (MR) |
|---|---|
| Assault / 企图殴打 | Causing V to apprehend immediate unlawful force. / 使受害人感知即将遭受立即非法暴力。 |
| Battery / 殴打 | Infliction of unlawful force on V. / 对受害人施加非法暴力。 |
| s.47 ABH / 实际身体伤害 | Assault or battery causing actual bodily harm (hurt/injury beyond transient). MR: same as assault/battery (Savage; Parmenter). / 殴打或企图殴打造成实际身体伤害。MR：与殴打/企图殴打相同。 |
| s.20 GBH / 恶意伤害 | Unlawfully wounding or inflicting grievous bodily harm (really serious harm). MR: some foresight of some harm (recklessness, Cunningham). / 非法致伤或造成严重身体伤害。MR：预见会有某种伤害（轻率，Cunningham标准）。 |
| s.18 GBH with Intent | Wounding or causing GBH with intent to do GBH or resist/prevent lawful arrest. MR: specific intent. / 故意致伤或造成严重身体伤害，并带有造成GBH的意图。MR：特定意图。 |
5. Property Offences: Theft & Robbery | 财产犯罪：盗窃与抢劫
Theft is defined by statute and requires a careful dissection of its five core elements. Burglary and robbery are aggravated forms of theft, each adding further physical or locational elements that increase culpability and punishment.
盗窃由成文法定义，需仔细剖析其五个核心要素。入室盗窃与抢劫是盗窃的加重形式，各自增加了提升罪责与刑罚的身体或地点要素。
roperty belonging to another with the intention of permanently depriving the other of it (s.1 Theft Act 1968)
盗窃 = 被告不诚实地占有属于他人的财产，并有永久剥夺他人财产的意图（1968年《盗窃法》第1条）
| Element / 要素 | Key Case / Test | 关键案例 / 标准 |
|---|---|
| Appropriation / 占有 | Any assumption of the rights of an owner (Morris; Gomez). Can occur even with consent. / 任何行使物主权利的行为。即使有物主同意也能发生。 |
| Property / 财产 | Money, real, personal, things in action, other intangible property. Excludes wild plants, confidential info. / 金钱、不动产、动产、诉讼上的财产、其他无形财产。不包括野生植物、机密信息。 |

| Dishonesty / 不诚实 | (i) Actual state of D's knowledge as to the facts; (ii) was D's conduct dishonest by the standards of ordinary decent people? (Ivey). / (i) 被告对事实的实际认知状态；(ii) 按普通正派人的标准，被告行为是否不诚实？(Ivey案)。 |
| Intention to Permanently Deprive | Treating the thing as one's own regardless of the other's rights (Lloyd). Borrowing may suffice if value is taken. / 将财物视为己有而不顾他人权利（Lloyd案）。如果获取了财物价值，借用也能构成此意图。 |
r threat of force) immediately before or at the time of stealing, in order to steal (s.8).
抢劫 = 盗窃 + 在盗窃过程中及为了盗窃，立即或在当时使用暴力（或威胁使用暴力）（第8条）。
6. Tort Law: Negligence Formula | 侵权法：过失侵权公式
Negligence forms the backbone of tort law, providing a remedy for harm caused by careless conduct. To succeed, a claimant must establish each sequential element, building from the duty of care through to damage that is not too remote.
过失侵权是侵权法的支柱，为因疏忽行为造成的损害提供救济。原告必须依次证明每一个要素，从注意义务逐步推进到并非太过遥远而不可预见的损害。
ce = Duty of Care + Breach of Duty + Causation (Factual & Legal) + Damage (Not Too Remote)
过失侵权 = 注意义务 + 违反义务 + 因果关系（事实与法律） + 损害（非太遥远）
| Element / 要素 | Key Test / 关键标准 |
|---|---|
| Duty of Care / 注意义务 | Neighbour principle (Donoghue v Stevenson): reasonable foreseeability of harm to someone in C's class; proximity; fair, just and reasonable to impose duty (Caparo). / 邻人原则（Donoghue v Stevenson案）：可合理预见会对原告同类人造成损害；关联性；施加义务公平、公正且合理（Caparo案）。 |
| Breach of Duty | D fell below the standard of the reasonable person (Blyth). Factors: probability of harm, seriousness of risk, cost of precautions, social utility (Bolton). / 被告行为低于合理人的标准（Blyth案）。考量因素：损害概率、风险严重性、预防成本、社会效用（Bolton案）。 |
| Causation / 因果关系 | Factual: 'But for' test (Barnett). Legal: novus actus interveniens, multiple causes. / 事实因果：“若非”检验（Barnett案）。法律因果：新介入行为、多重原因。 |
| Remoteness / 损害的遥远性 | Damage must be of a type that was reasonably foreseeable (The Wagon Mound). Take victim as you find them (thin skull rule). / 损害必须属于可合理预见的类型（Wagon Mound案）。接受受害人的既有体质（薄颅骨规则）。 |
7. Occupiers' Liability Quick Tests | 占有人责任快速检验标准
Occupiers' liability statutes create specific duties owed to visitors and trespassers respectively. The 1957 Act provides robust protection to lawful visitors, while the 1984 Act offers a more limited, though important, duty to those who would historically have had no remedy.
占有人责任成文法分别为来访者与侵入者设定了具体的义务。1957年法律为合法来访者提供强有力保护，而1984年法律则为历史上无法获得救济的群体规定了较为有限但仍属重要的义务。
| Statute / 法律 | Key Formula / 核心公式 |
|---|---|
| OLA 1957 (Visitors / 来访者) | Occupier owes a 'common duty of care' to see that the visitor is reasonably safe in using the premises for the purpose for which they were invited. / 占有人负有“通常注意义务”，确保来访者在被邀请目的范围内使用场所时合理安全。 |
| OLA 1984 (Trespassers / 侵入者) | Duty arises if: (i) occupier is aware of the danger/has reasonable grounds to believe it exists; (ii) knows/has reasonable grounds to believe someone might come into the vicinity; (iii) the risk is one against which they may reasonably be expected to offer some protection (Tomlinson). / 义务产生条件：(i) 占有人知悉危险或有合理理由相信其存在；(ii) 知道或有合理理由相信有人可能进入附近；(iii) 该风险属于可合理期待他们提供某种保护的风险（Tomlinson案）。 |
8. Contract Formation: The Agreement Formula | 合同成立：协议公式
A binding contract requires an agreement supported by consideration and an intention to create legal relations. The process of offer and acceptance is analysed objectively, and the courts look for a meeting of the minds evidenced by conduct and communication.
一个有约束力的合同需要以对价支持并有创设法律关系意图的协议。要约与承诺的过程依客观标准分析，法院寻找通过行为与沟通所证明的意思表示一致。
ract = Offer + Acceptance + Consideration + Intention to Create Legal Relations + Capacity
合同 = 要约 + 承诺 + 对价 + 创设法律关系意图 + 行为能力
| Element / 要素 | Key Rule / 核心规则 |
|---|---|
| Offer / 要约 | A clear statement of terms on which the offeror is willing to be bound, distinguished from an invitation to treat (Fisher v Bell; Partridge v Crittenden). / 明确陈述要约人愿意据此受约束的条款，区别于要约邀请（Fisher v Bell案；Partridge v Crittenden案）。 |
| Acceptance / 承诺 | Unconditional agreement to all terms of the offer; generally must be communicated (Felthouse). Postal rule: acceptance effective on posting (Adams v Lindsell). / 对要约所有条款无条件同意；通常必须传达（Felthouse案）。投邮规则：承诺于投邮时生效（Adams v Lindsell案）。 |
| Consideration / 对价 | Something of value given by each party. Must be sufficient but need not be adequate; must not be past (Re McArdle). Performance of an existing duty is generally not good consideration (Stilk v Myrick). / 各方给出的有价值之物。必须充分但不必等价；不得是过去的对价（Re McArdle案）。履行现有义务通常不构成有效对价（Stilk v Myrick案）。 |
| Intention / 意图 | Social/domestic: presumed no intention (Balfour). Commercial: presumed intention (Edwards v Skyways). Rebuttable by evidence. / 社交/家庭关系：推定无意图（Balfour案）。商业关系：推定有意图（Edwards v Skyways案）。均可通过证据推翻。 |
9. Contractual Terms vs Representations | 合同条款与陈述对比
Not everything said during negotiations becomes a term of the contract. The distinction determines whether a remedy lies in breach of contract or misrepresentation, each carrying different consequences and measures of damages.
谈判中所说的一切并非都会成为合同条款。这一区分决定救济途径是违约还是虚假陈述，各自带来不同的结果与损害赔偿计算方式。
| Category / 类别 | Definition & Test | 定义与标准 |
|---|---|
| Condition / 条件条款 | A major term going to the root of the contract; breach entitles the innocent party to terminate and claim damages (Poussard). / 触及合同根基的主要条款；违反时无过错方可终止合同并索赔（Poussard案）。 |
| Warranty / 保证条款 | A minor, subsidiary term; breach gives right to damages only, not termination (Bettini). / 次要、附属条款；违反时仅能索赔，不可终止合同（Bettini案）。 |
| Innominate Term | Look at the consequences of the breach: if it deprives the injured party of substantially the whole benefit, treated as a condition (Hong Kong Fir). / 看违约后果：若剥夺了受损方实质上全部合同利益，则视同条件条款处理（Hong Kong Fir案）。 |
10. Human Rights: Core Articles Quick Reference | 人权：核心条款速查
The European Convention on Human Rights (ECHR), incorporated into UK law via the Human Rights Act 1998, provides a catalogue of protected rights. Understanding the structure of absolute, limited, and qualified rights is essential for analysing whether an interference is lawful.
《欧洲人权公约》(ECHR) 通过1998年《人权法》被纳入英国法律，提供了一个受保护权利的清单。理解绝对权利、有限权利与附条件权利的结构，对于分析一项干预是否合法至关重要。

Proportionality Test for Qualified Rights: The interference must be (i) prescribed by law, (ii) pursue a legitimate aim, and (iii) be necessary in a democratic society (proportionate).
附条件权利的相称性检验： 干预必须 (i) 为法律所规定，(ii) 追求一项正当目的，且 (iii) 在民主社会中属必要（相称）。
11. Criminal Defences Quick Reference | 刑事抗辩事由速查
Even where the actus reus and mens rea are present, a defendant may avoid liability by raising a recognised defence. Some defences result in a complete acquittal, while others reduce liability from murder to voluntary manslaughter.
即便存在犯罪行为与犯罪心理，被告仍可通过提出公认的抗辩事由避免责任。有些抗辩导致完全无罪释放，而另一些则将责任从谋杀减轻为自愿误杀。
| Defence / 抗辩 | Core Test / 核心标准 | Effect / 效果 |
|---|---|---|
| Insanity / 精神错乱 | M'Naghten Rules: defect of reason from disease of the mind causing D not to know the nature/quality of the act or that it was wrong. / M'Naghten规则：因精神疾病导致理性缺陷，使被告不知行为性质/特征或不知其为错误。 | Special verdict: 'not guilty by reason of insanity'. / 特殊裁断：“因精神错乱而无罪”。 |
