1. Criminal Liability Equation | 刑事责任公式
lity. Actus reus comprises conduct, circumstances, and consequences, while mens rea refers to the mental element such as intention or recklessness.
刑事责任的基本公式为：犯罪行为 + 犯罪意图 + 无辩护理由 = 刑事责任。犯罪行为包括行为、状态和结果，而犯罪意图指故意或轻率等主观要素。
The actus reus must be voluntary, as confirmed in Hill v Baxter (1958). Automatism can negate the actus reus if the defendant's actions were wholly beyond their control.
犯罪行为必须是自愿的，正如 Hill v Baxter（1958）案所确认。若被告行为完全超出其控制，自动化症可否定犯罪行为。
Mens rea varies by offence. Direct intent (aim or purpose) is the highest form, while oblique intent (foresight of virtual certainty) applies where the consequence was not the aim but was almost certain, as in R v Woollin (1999).
犯罪意图因罪行而异。直接故意（目的或目标）是最高形式，而间接故意（预见到事实上必然发生的结果）适用于结果并非目的但几乎必然发生的情形，如 R v Woollin（1999）案。
Recklessness involves taking an unjustifiable risk of which the defendant was aware. For most non-fatal offences, subjective recklessness applies (R v Cunningham [1957]), meaning the defendant must have foreseen the risk and unreasonably taken it.
轻率指被告意识到不正当风险却仍冒险。大多数非致命人身罪适用主观轻率（R v Cunningham [1957]），即被告必须预见到该风险且不合理地冒险。
2. Causation Formula | 因果关系公式
sation: Factual Causation + Legal Causation = Causation in Law. Factual causation uses 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 [1910]).
若犯罪行为需要结果，控方必须证明因果关系：事实因果关系 + 法律因果关系 = 法律上的因果关系。事实因果关系采用“若非”检验：“若非被告行为，结果会发生吗？”若答案为否，事实因果关系即成立（R v White [1910]）。
Legal causation requires the defendant's act to be an operating and substantial cause of the result. R v Smith (1959) affirmed the act need not be the sole cause but must contribute more than minimally. The chain of causation can be broken by a novus actus interveniens, but only if it is free, deliberate, and informed (R v Kennedy (No 2) [2007]).
法律因果关系要求被告行为是结果的有效且实质原因。R v Smith（1959）案确认行为不必是唯一原因，但须超出极小贡献。因果关系链条可被新的介入行为打断，但仅当该行为是自由、故意且知情的（R v Kennedy (No 2) [2007]）。
Medical negligence will not break the chain unless it is so potent as to render the original wound merely part of the history (R v Cheshire [1991]). The thin skull rule means the defendant must take their victim as they find them (R v Blaue [1975]).
医疗过失不会打断链条，除非其极其强大，使原伤害成为历史背景的一部分（R v Cheshire [1991]）。薄头盖骨规则意味着被告必须接受受害人的原有状态（R v Blaue [1975]）。
3. Non-Fatal Offences Structure | 非致命人身罪的构成
nlawful force + intention or recklessness as to that force. The force need not be hostile, as held in Faulkner v Talbot (1981).
普通袭击 = 使受害人恐惧即将遭受非法暴力的行为 + 对此恐惧的故意或轻率。殴击 = 非法暴力的施加 + 对此暴力的故意或轻率。暴力不必须具有敌意，参见 Faulkner v Talbot（1981）。
al bodily harm = assault or battery + actual bodily harm (more than transient or trifling, R v Donovan [1934]). The mens rea is the same as the underlying assault or battery; no additional mens rea for the harm is required.
《1861 年侵犯人身罪法》第 47 条：袭击致实际身体伤害 = 普通袭击或殴击 + 实际身体伤害（超越短暂或轻微，R v Donovan [1934]）。犯罪意图与基础袭击或殴击相同；无需对伤害有额外犯意。
g grievous bodily harm = wound (break in both layers of skin) or GBH (really serious harm, DPP v Smith [1961]) + 'maliciously' meaning intention or subjective recklessness as to some harm. 'Inflict' includes psychiatric injury (R v Burstow [1997]).
第 20 条：恶意伤害或造成严重身体伤害 = 创伤（皮肤两层均破损）或 GBH（真正严重的伤害，DPP v Smith [1961]）+ “恶意”指对某种伤害有故意或主观轻率。“造成”包括精神伤害（R v Burstow [1997]）。
o cause GBH (or intention to resist arrest with recklessness as to causing GBH). It is a specific intent offence and carries a maximum of life imprisonment.
第 18 条：意图致严重身体伤害的创伤或 GBH = 创伤或 GBH + 造成 GBH 的故意（或抗拒逮捕的故意并对造成 GBH 轻率）。属特定故意罪行，最高可判终身监禁。
4. Murder Formula and Voluntary Manslaughter | 谋杀公式与自愿性过失杀人
Murder = unlawful killing of a reasonable creature in being under the King's peace + with malice aforethought (intention to kill or cause grievous bodily harm). The 'GBH rule' from R v Cunningham [1982] makes murder a constructive malice crime as to harm intended, not death.
谋杀 = 在王国和平之下对活着的人的非法杀害 + 具有预怀恶意（故意杀人或故意造成严重身体伤害）。R v Cunningham [1982] 案的“GBH 规则”使谋杀成为一个对伤害（而非死亡）具有推定恶意的犯罪。
Voluntary manslaughter arises where the defendant satisfies the actus reus and mens rea of murder but successfully pleads a partial defence. The three main partial defences are: loss of control, diminished responsibility, and suicide pact (rare).
自愿性过失杀人适用于被告满足谋杀的犯罪行为和犯意但成功提出部分辩护的情形。三个主要部分辩护是：失去控制、减轻责任和自杀协定（罕见）。
Loss of Control (Coroners and Justice Act 2009, s.54-55): defendant's act resulted from a loss of self-control, the loss had a qualifying trigger (fear of serious violence or things said/done of an extremely grave character or a combination), and a person of the defendant's sex and age with a normal degree of tolerance and self-restraint might have acted similarly.
失去控制（《2009 年验尸官与司法法》第 54-55 条）：被告行为源于失去自控，该失控具有适格触发因素（恐惧严重暴力、具有极为严重性质的事言或行为，或二者结合），且与被告同性别、同年龄且具有正常程度的宽容和自制的常人可能作出类似反应。
Diminished Responsibility (Homicide Act 1957, s.2 as amended by the 2009 Act): defendant suffered from an abnormality of mental functioning arising from a recognised medical condition, which substantially impaired their ability to understand the nature of their conduct, form a rational judgment, or exercise self-control, and it provides an explanation for the killing.
减轻责任（《1957 年杀人罪法》第 2 条经 2009 年法修正）：被告因公认医疗状况导致心理功能异常，该异常严重削弱其理解行为性质、作出理性判断或行使自控的能力，并解释了杀人行为。
5. Theft Law Formula | 盗窃罪公式
stly appropriating property belonging to another with the intention of permanently depriving the other of it. Each element must be satisfied simultaneously.
盗窃（《1968 年盗窃罪法》第 1 条）= 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财产的意图。每个要素必须同时满足。
'Appropriation' (s.3) includes any assumption of the rights of an owner, even if the victim consents, provided the consent was obtained by deception (R v Gomez [1993]). The case of R v Hinks [2001] confirmed that appropriation can occur where a gift is obtained, provided it is dishonest.
“据为己有”（第 3 条）包括任何行使所有人权利的行为，即使受害人同意，只要该同意系通过欺骗获得（R v Gomez [1993]）。R v Hinks [2001] 案确认，若获取礼物不诚实，即使礼物表面有效转移，亦可构成据为己有。
'Property' (s.4) includes money, real property, personal property, things in action, and other intangible property. Land can be stolen only in limited circumstances. Wild creatures are generally not property unless tamed or kept in captivity.
“财产”（第 4 条）包括金钱、不动产、动产、无形财产和其他无体物。土地仅能在有限情形下被盗。一般野生生物不属于财产，除非被驯化或圈养。
'Belonging to another' (s.5) covers any person having possession or control or a proprietary right or interest. Importantly, s.5(3) states that property received under an obligation to deal with it in a particular way belongs to the giver if that obligation is not discharged.
“属于他人”（第 5 条）涵盖任何拥有、控制或享有所有权或权益的人。重要的是第 5(3) 条指出，若收到财产时有义务以特定方式处理，则未履行义务时该财产仍属于给予者。
'Dishonesty' is now assessed under the Ivey v Genting Casinos [2017] test: what was the defendant's actual state of knowledge or belief as to the facts? In that context, was their conduct dishonest by the standards of ordinary decent people? S.2 provides three situations where appropriation is not dishonest.
“不诚实”现依 Ivey v Genting Casinos [2017] 检验标准确定：被告对事实的实际认知或信念如何？在该情境下，按普通正派人士的标准其行为是否不诚实？第 2 条规定三种不构成不诚实的情形。
'Intention to permanently deprive' (s.6): borrowing or lending may amount to such intention if it is for a period and in circumstances making it equivalent to an outright taking. Conditional intention, e.g., 'If there is something worth stealing', is insufficient for theft but may support attempted theft.
“永久剥夺意图”（第 6 条）：若借用或借出的期限和情况使其等同于完全取走，则可构成该意图。附条件意图，如“若里面有值得偷的东西”，不足以构成盗窃，但可支持企图盗窃。
6. Negligence Duty of Care Formula | 过失注意义务公式
To establish negligence, a claimant must prove: Duty of Care + Breach of Duty + Causation of Damage + Remoteness of Damage. The modern test for duty in novel situations derives from Caparo Industries plc v Dickman [1990]: foreseeability of harm, proximity between the parties, and that it is fair, just and reasonable to impose a duty.
要证明过失成立，索赔人须证明：注意义务 + 违反义务 + 因果关系的损害 + 损害的远隔性。在新类型情形中，注意义务的现代检验源自 Caparo Industries plc v Dickman [1990]：损害可预见性、当事方之间的近邻关系，以及课以义务公平、公正且合理。
Established duty situations include: doctor-patient, employer-employee, road users to one another, occupier-visitor (now governed by the Occupiers' Liability Act 1957). The policy considerations behind Caparo allow courts to decline to impose a duty, e.g., police in investigating crime (Hill v Chief Constable of West Yorkshire [1989]).
已确立的义务情形包括：医患关系、雇主-雇员、道路使用者之间、占用人-访客（现由《1957 年占用人责任法》管辖）。Caparo 所蕴含的政策考量允许法院拒绝课予义务，例如警方调查犯罪（Hill v Chief Constable of West Yorkshire [1989]）。
7. Breach of Duty and Standard of Care | 违反义务与注意标准
Breach occurs where the defendant fails to meet the standard of the reasonable person. The 'reasonable person' test (Blyth v Birmingham Waterworks [1856]) is objective. Special standards apply: child defendants are judged against the reasonable child of the same age (Mullin v Richards [1998]); professionals against the standard of the ordinary competent practitioner in that field (Bolam v Friern Hospital Management Committee [1957]).
当被告未达到合理人的标准时即构成违反。合理人检验（Blyth v Birmingham Waterworks [1856]）是客观的。特殊标准适用：儿童被告以同龄合理儿童为标准（Mullin v Richards [1998]）；专业人士以该领域普通胜任从业者的标准为准（Bolam v Friern Hospital Management Committee [1957]）。
To determine breach, the court weighs four main factors: likelihood of harm, seriousness of potential harm, cost of taking precautions, and social utility of the defendant's activity (Watt v Hertfordshire County Council [1954]). This is essentially a cost-benefit formula.
法院判断是否违反时考量四个主要因素：损害发生的可能性、潜在损害的严重性、采取预防措施的成本，以及被告活动的社会效用（Watt v Hertfordshire County Council [1954]）。这本质上是一个成本-收益公式。
Res ipsa loquitur ('the thing speaks for itself') shifts the evidential burden where the cause of the accident is unknown, the defendant had control, and in the ordinary course of things the accident would not have happened without negligence (Scott v London and St Katherine Docks Co [1865]).
事实自证（“事情不言自明”）在事故原因不明、被告具有控制力且按通常情形若无过失事故不会发生时转移证据负担（Scott v London and St Katherine Docks Co [1865]）。
8. Contract Formation Formula | 合同成立公式
A binding contract requires: Offer + Acceptance + Consideration + Intention to Create Legal Relations. The offer must be a clear statement of terms, distinguishable from an invitation to treat (Pharmaceutical Society of Great Britain v Boots Cash Chemists [1953]).
一个具有约束力的合同需要：要约 + 承诺 + 对价 + 创制法律关系的意图。要约必须是明确的条件陈述，可与要约邀请相区分（Pharmaceutical Society of Great Britain v Boots Cash Chemists [1953]）。
Acceptance must mirror the terms of the offer (the 'mirror image rule') and be communicated. The postal rule (Adams v Lindsell [1818]) states acceptance by post is effective upon posting, provided it was reasonable to use the post. This does not apply to instantaneous methods of communication.
承诺必须镜像要约条件（“镜像规则”）并进行传达。邮寄规则（Adams v Lindsell [1818]）规定，以邮寄方式承诺在投邮时即生效，前提是使用邮寄方式合理。该规则不适用于即时通讯方式。
Consideration must be something of value in the eyes of the law, moving from the promisee, but need not be adequate (Thomas v Thomas [1842]). Past consideration is not good consideration unless an earlier request and implied promise exist (Lampleigh v Brathwait [1615]). Performance of an existing contractual duty owed to a third party can be good consideration (Scotson v Pegg [1861]).
对价必须在法律眼中具有价值，由受诺人提供，但无需足够（Thomas v Thomas [1842]）。过去的对价不是有效对价，除非此前存在请求和默示允诺（Lampleigh v Brathwait [1615]）。履行对第三人负有的现有合同义务可构成有效对价（Scotson v Pegg [1861]）。
Intention to create legal relations is presumed in commercial agreements but rebuttable. In social or domestic agreements, the presumption is against legal relations unless evidence of intention exists (Jones v Padavatton [1969]). These presumptions can be displaced by clear language.
创制法律关系的意图在商业协议中可被推定，但可反驳。在社会或家庭协议中，推定不具法律关系，除非有意图证据（Jones v Padavatton [1969]）。这些推定可通过清晰措辞被推翻。
9. Judicial Precedent Hierarchy | 司法先例层级
The doctrine of precedent (stare decisis) requires courts to follow decisions of higher courts in similar cases. The Supreme Court (formerly the House of Lords) binds all lower courts but may depart from its own previous decisions under the Practice Statement 1966 when it appears right to do so.
先例原则（遵循先例）要求法院在类似案件中遵循上级法院的判决。最高法院（原上议院）约束所有下级法院，但可依 1966 年实践声明在认为适当的情形下偏离其先前的判决。
The Court of Appeal (Civil Division) is bound by the Supreme Court and normally by its own previous decisions, subject to the exceptions in Young v Bristol Aeroplane Co Ltd [1944]: conflicting decisions, decisions made per incuriam, or where a decision is impliedly overruled by the higher court. The Criminal Division applies similar rules but with flexibility to prevent injustice.
上诉法院（民事庭）受最高法院及其自身先前判决的约束，但存在 Young v Bristol Aeroplane Co Ltd [1944] 案所定例外：判决相互冲突、因缺乏注意而作出的判决，或判决被上级法院默示推翻。刑事庭适用类似规则，但为防止不公更具灵活性。
The ratio decidendi of a case is the legal principle necessary for the decision and forms the binding precedent. Obiter dicta are statements made 'by the way' and are persuasive only, though high court obiter can carry significant weight.
案件的判决理由是作出决定所必需的法律原则，构成具约束力的先例。附论是“附带”陈述，仅具说服效力，但高等法院的附论可能具有重大分量。
10. Statutory Interpretation Tools | 法规解释工具
Courts interpret statutes using three main rules: the literal rule (follow the ordinary dictionary meaning, e.g., Whitely v Chappell [1868]), the golden rule (modify the literal meaning to avoid absurdity, e.g., R v Allen [1872]), and the mischief rule (look at the gap the statute aimed to fill, Smith v Hughes [1960]).
法院运用三个主要规则解释法规：文义规则（遵循普通词典含义，如 Whitely v Chappell [1868]），黄金规则（为避免荒谬而修改文义，如 R v Allen [1872]），以及弊端规则（考察制定法旨在填补的漏洞，Smith v Hughes [1960]）。
The purposive approach, influenced by EU law and the Human Rights Act 1998, gives effect to the overall purpose of the legislation. Section 3 HRA 1998 requires courts to read and give effect to legislation in a way compatible with Convention rights, so far as it is possible to do so.
受欧盟法及 1998 年人权法影响的立法目的解释方法，力求实现立法的整体目的。1998 年人权法第 3 条要求法院在尽可能的范围内以符合公约权利的方式解释并适用立法。
Internal aids (within the statute itself) include the long title, preamble, short title, and any interpretation section. External aids include dictionaries, previous legislation, Hansard (parliamentary debates, under Pepper v Hart [1993]), and Law Commission reports.
内部辅助资料（制定法内部）包括长标题、序言、短标题及任何解释条款。外部辅助资料包括词典、先前立法、议会辩论记录（依 Pepper v Hart [1993]）及法律委员会报告。
11. Human Rights Balancing Formula | 人权平衡公式
Articles under the European Convention on Human Rights often follow a structured formula. For example, Article 8 (right to respect for private and family life) involves a two-stage test: (1) Is there an interference with the right? (2) If so, is that interference 'in accordance with the law', pursuing a legitimate aim, and 'necessary in a democratic society' (proportionate)?
《欧洲人权公约》条款通常遵循结构化公式。例如第 8 条（私人和家庭生活受尊重权）涉及两阶段检验：（1）是否存在对权利的干预？（2）若是，该干预是否“依法”，追求合法目的，且为“民主社会所需”（相称）？
Qualified rights like Article 9, 10, and 11 share this proportionality framework. The courts must strike a fair balance between the individual's rights and the general interest of the community. Bank Mellat [2013] UKSC set out a four-part proportionality test: the objective must be sufficiently important, the measure must be rationally connected to it, a less intrusive alternative must be considered, and overall a fair balance must be struck.
诸如第 9、10 和 11 条等有限制条款的权利均适用此相称性框架。法院必须在个人权利与共同体的普遍利益之间实现公平平衡。Bank Mellat [2013] UKSC 提出了四部分相称性检验：目标必须足够重要，措施必须与之具有理性关联，必须考虑侵入性更小的替代方案，且总体上必须实现公平平衡。
12. Defences Quick-Reference | 辩护理由速查
In criminal law, general defences can be full (leading to acquittal) or partial (reducing murder to manslaughter). Self-defence combines common law and statutory elements (Criminal Justice and Immigration Act 2008). The formula: honest belief in the need to defend + reasonable force in the circumstances as the defendant believed them to be. Pre-emptive strikes can be permitted if genuine belief exists.
在刑法中，一般辩护理由可以是完全的（导致无罪）或部分的（将谋杀减为过失杀人）。自卫结合了普通法和成文法要素（2008 年刑事司法与移民法）。公式为：真诚地相信有必要防卫 + 在被告所相信的情形下使用合理武力。若存在真诚相信，先发制人的打击可被允许。
Insanity (M'Naghten Rules) is a full defence based on a defect of reason arising from a disease of the mind causing the defendant not to know the nature and quality of the act, or not to know that it was wrong. It leads to a special verdict of 'not guilty by reason of insanity'.
精神失常（M'Naghten 规则）是完全辩护理由，其基于因精神疾病导致的理性缺陷，致使被告不知行为性质，或不知行为是错误的。该辩护导致“因精神失常无罪”的特别裁决。
Duress by threats is a full defence to all crimes except murder and attempted murder, and possibly treason. The test: defendant was impelled to commit a crime because they reasonably feared death or serious injury, and a sober person of reasonable firmness sharing the defendant's characteristics would have acted similarly (R v Graham [1982]).
胁迫之威胁是对除谋杀和企图谋杀（可能包括叛国罪）之外所有罪行的完全辩护。检验为：被告因合理担心死亡或严重伤害而被迫犯罪，且一个具有合理坚定性的清醒者，共享被告特征，亦会作出同样反应（R v Graham [1982]）。
