尽管法律并非数学学科，但许多法律规则遵循逻辑结构，可归纳为便于记忆的方程、清单和原则。本速查手册将 GCSE Eduqas 法律大纲的核心概念提炼为“公式”，帮助你构建复习体系，精准应对考试题目。
1. The Criminal Liability Equation | 刑事责任方程式
simple equation: Actus Reus + Mens Rea + Absence of a valid defence = Criminal liability.
刑法的基础可用一个简单方程表示：犯罪行为 + 犯罪意图 + 无有效辩护理由 = 刑事责任。
Actus reus refers to the guilty act. It can consist of conduct, a consequence, or a state of affairs. The prosecution must prove the defendant committed a voluntary act, or in exceptional cases, an omission where a duty to act exists.
犯罪行为指过错行为。它可由作为、结果或事态构成。控方必须证明被告实施了自愿行为，或在例外情形下，存在作为义务而不作为。
Mens rea is the guilty mind. The main levels are intention (direct or oblique) and recklessness. Intention means it was the defendant's aim or purpose, or the outcome was virtually certain and the defendant appreciated this. Recklessness means the defendant foresaw a risk of the prohibited consequence and unreasonably took that risk.
犯罪意图是过错心理。主要层级包括故意（直接或间接）和轻率。故意指被告的目的或意图，或后果几乎确定发生且被告明知此点。轻率指被告预见到禁止结果的风险，却不合理地冒了该风险。
The absence of a valid defence completes the equation. Even if actus reus and mens rea are present, a successful defence such as self-defence, duress or insanity will result in acquittal.
无有效辩护理由使方程完整。即使存在犯罪行为和犯罪意图，若自卫、胁迫或精神错乱等辩护成功，仍会导致无罪判决。
2. Actus Reus Components | 犯罪行为构成要素
Actus reus can be broken down into: Conduct + Circumstances + Consequence. Each element must be proved by the prosecution.
犯罪行为可分解为：行为 + 情节 + 结果。每一项均须由控方证明。
Conduct is the physical act or omission of the defendant. For example, in assault, the conduct is causing the victim to apprehend immediate unlawful force.
行为指被告的身体作为或不作为。例如，在威胁攻击罪中，行为是使受害人担心即将遭受非法暴力。
Circumstances are the surrounding facts that make the act unlawful. In theft, the property must belong to another. In criminal damage, the property must belong to another and be damaged without lawful excuse.
情节是使行为违法的事实背景。盗窃罪中财物须属于他人；刑事毁坏罪中财物须属于他人且无合法理由加以毁坏。
Consequence is the result required by the definition of the offence. For murder, the consequence is the death of a human being. Causation links the conduct to the consequence: factual causation ('but for' test) and legal causation (the defendant's act was a substantial and operating cause of the result).
结果是犯罪定义所要求的后果。谋杀罪的结果是他人死亡。因果关系将行为与结果连接起来：事实因果关系（“若无则不”测试）和法律因果关系（被告行为是结果的实质且有效原因）。
3. Levels of Mens Rea | 犯罪意图的等级
ion (oblique) → Recklessness → Gross negligence → Strict liability (no mens rea required).
犯罪意图按可责性从高到低排列：直接故意 → 间接故意 → 轻率 → 重大过失 → 严格责任（无需犯罪意图）。
Direct intention is when the defendant acts with the aim or purpose of bringing about a prohibited consequence. It is the highest form of fault.
直接故意指被告以实现禁止结果为目的或目标而行事。这是最高形式的过错。
Oblique intention applies when the consequence was not the defendant's aim, but it was a virtually certain outcome of their actions and the defendant appreciated this virtual certainty.
间接故意适用于结果并非被告目标，但该结果是其行为的几乎确定后果，且被告对此心知肚明。
Recklessness is where the defendant foresaw a risk of the consequence occurring and in the circumstances known to them, it was unreasonable to take that risk. This is the standard for many non-fatal offences and criminal damage.
轻率指被告预见到结果发生的风险，且在当时已知情况下冒该风险是不合理的。这是许多非致命犯罪和刑事毁坏的标准。
Strict liability offences require no proof of mens rea as to one or more elements of the actus reus. These are mainly regulatory crimes, such as selling alcohol to a minor.
严格责任犯罪无需证明犯罪行为中一项或多项要素的犯罪意图。这些主要是监管类犯罪，如向未成年人售酒。
4. Non-Fatal Offences Quick Formulae | 非致命犯罪速查公式
Memorise these equations for the main non-fatal offences against the person:
请记住以下针对人身的非致命犯罪主要方程：
hend immediate unlawful force + Intention or recklessness as to causing such apprehension.
威胁攻击 = 使受害人担心即将遭受直接非法暴力 + 故意或轻率地造成该担心理由。
iction of unlawful force on V + Intention or recklessness as to inflicting unlawful force.
殴打 = 对受害人施加非法暴力 + 故意或轻率地施加非法暴力。
of actual bodily harm (any hurt or injury calculated to interfere with health or comfort).
威胁攻击或殴打致实际身体伤害 (ABH) = 威胁攻击或殴打 + 造成实际身体伤害（任何足以影响健康或舒适的伤痛）。
ful wounding or infliction of GBH + Malice (intention or recklessness as to some harm, albeit not serious harm).
恶意伤害或造成严重身体伤害 (GBH) 第20条 = 非法伤害或造成严重身体伤害 + 恶意（故意或轻率地造成一些伤害，即使并非严重伤害）。
ic intention to cause GBH or resist/prevent lawful arrest. This is the most serious non-fatal offence.
意图造成严重身体伤害的伤害或重伤第18条 = 伤害或造成严重身体伤害 + 特定意图造成严重身体伤害或抗拒/阻止合法逮捕。这是最严重的非致命犯罪。
5. Homicide Offences Formulae | 杀人犯罪公式
Murder = Unlawful killing of a reasonable person under the Queen's peace + Malice aforethought (intention to kill or cause GBH).
谋杀 = 在女王治下非法杀害具有合理人格者 + 恶意预谋（意图杀人或造成严重身体伤害）。
l + Qualifying trigger (fear of serious violence or things said/done of extremely grave character causing a justifiable sense of being seriously wronged) + A person of the defendant's sex and age with a normal degree of tolerance would have acted in the same way.
失控杀人（谋杀的部分辩护，可减为非预谋杀人罪） = 被告失去自控 + 合格触发事由（担心严重暴力，或所说所做之事性质极其严重，使人合情合理感到深受冤屈） + 一个与被告同性别、同年龄且具备正常容忍度的人也会如此行动。
mental functioning arising from a recognised medical condition + Substantially impaired defendant' rm rational judgement, or exercise self-control + Provides an explanation for the killing.
减轻责任（谋杀部分辩护）= 由公认医学状况引起的精神功能异常 + 实质上损害了被告理解行为性质、形成理性判断或行使自控力的能力 + 为此杀人提供解释。
onal unlawful act (crime) + The act was dangerous on an objective test + The act caused the victim's death. No mens rea as to death is required.
非法行为非预谋杀人 = 故意不法行为（犯罪） + 该行为在客观上具有危险性 + 该行为导致受害人死亡。无需对死亡有犯罪意图。
6. General Defences Cheat Sheet | 一般辩护速查表
force + Level of force used was reasonable in the circumstances as the defendant believed them to be.
辩护可表示为否定责任的条件：自卫 = 真诚相信有必要使用武力 + 在当时被告人所相信的情境下使用的武力程度合理。
serious injury + Threat made to the defendant or a person for whom they reasonably regard themselves as responsible + The threat caused the defendant to commit the offence + A sober person of reasonable firmness sharing the defendant's characteristics would have responded in the same way.
胁迫辩护 = 死亡或严重伤害威胁 + 威胁针对被告人或其合理认为负有责任的人 + 该威胁导致被告人犯罪 + 一个与被告人具有相同特征、有合理坚定性的清醒人士也会做出同样反应。
Insanity (M' m disease of the mind + The defendant did not know the nature and quality of the act, or if they did, they did not know it was wrong.
精神错乱（麦克纳顿规则）= 因精神疾病导致理性缺陷 + 被告不知行为性质和本质，或即使知道，也不知行为是错误的。
Intoxication – voluntary intoxication can negate specific intent but not basic intent; involuntary intoxication can be a defence if it renders the defendant unable to form mens rea.
醉态——自愿醉态可否定特定意图，但不能否定基本意图；非自愿醉态若使被告无法形成犯罪意图，则可构成辩护。
7. Tort of Negligence Formula | 疏忽侵权公式
hat duty + Causation + Damage. All four elements must be satisfied for a successful claim.
疏忽侵权 = 注意义务 + 违反该义务 + 因果关系 + 损害。四项要素全部满足方可成功索赔。
Duty of care is established using the Caparo three-part test: (1) Was the damage or injury reasonably foreseeable? (2) Was there a relationship of sufficient proximity between claimant and defendant? (3) Is it fair, just and reasonable in all the circumstances to impose a duty of care?
注意义务通过 Caparo 三阶段测试确立：(1) 损害或伤害是否合理可预见？(2) 原告与被告之间是否有足够邻近关系？(3) 在所有情形下，施加注意义务是否公平、公正且合理？
Breach occurs when the defendant falls below the standard of the reasonable person. The court will consider factors such as the likelihood of harm, the seriousness of potential harm, the cost and practicality of taking precautions, and any social utility of the defendant's conduct.
当被告的行为低于合理人标准时，即为义务违反。法庭将考量损害发生的可能性、潜在损害的严重性、采取预防措施的成本和可行性以及被告行为的社会效益等因素。
Causation requires proof of both factual causation (the 'but for' test) and legal causation (the damage was not too remote – it must be of a reasonably foreseeable type). A new intervening act may break the chain of causation.
因果关系需同时证明事实因果关系（“若无则不”测试）和法律因果关系（损害并非过于遥远——须属合理可预见类型）。新的介入行为可中断因果关系链。
8. Trespass to the Person Formulae | 侵害人身侵权公式
t by the defendant that causes the claimant to reasonably apprehend an imminent battery + The claimant need not suffer physical injury.
威胁攻击（侵权法）= 被告故意行为使原告合理担心即将遭受直接殴打 + 原告无需遭受身体伤害。
ional application of unlawful force to the claimant without consent or other lawful justification. Hostility is not required.
殴打（侵权法）= 未经同意或其他合法理由，直接且故意向原告施加非法暴力。无需存在敌意。
False imprisonment = Complete restraint of the claimant' estriction is not sufficient. The claimant need not be aware of the restraint at the time.
错误拘禁 = 被告无合法权限完全限制原告行动自由。限制须为完全限制；部分限制不构成。原告被限制时不必知悉。
9. Contract Formation Formula | 合同成立公式
Consideration + Intention to create legal relations + Capacity. Each element must be present at the moment of formation.
有效合同 = 要约 + 承诺 + 对价 + 建立法律关系的意图 + 缔约能力。成立时每项要素均须具备。
An offer is an expression of willingness to contract on specific terms, made with the intention that it will become binding upon acceptance. It must be distinguished from an invitation to treat, which is an invitation to negotiate (e.g., goods displayed on a shelf).
要约是表明愿意按特定条款订约的表示，且意在一经承诺即受约束。须与要约邀请区分，后者是邀请谈判（例如货架陈列商品）。
Acceptance must be an unconditional agreement to all terms of the offer. It must generally be communicated to the offeror, although the postal rule may apply where acceptance is effective upon posting.
承诺必须是对所有要约条款的无条件同意。通常须传达至要约人，但邮寄规则可能适用，即承诺在投邮时即生效。
Consideration is something of value given by each party. It can be an act, a forbearance, or a promise. It must be sufficient but need not be adequate. Past consideration is not valid consideration.
对价是各方给予的有价值事物。可以是作为、不作为或一项允诺。对价必须充分但不必相当。过去对价非有效对价。
Intention to create legal relations is presumed in commercial agreements and rebutted in social or domestic arrangements, unless evidence shows otherwise.
建立法律关系的意图在商业协议中推定存在，在社交或家庭安排中推定不存在，除非有相反证据。
10. Contract Terms and Breach Quick Reference | 合同条款与违约速查
Terms of a contract can be expressed or implied. Express terms are explicitly agreed; implied terms are read into the contract by statute (e.g., Sale of Goods Act) or by the courts to give business efficacy.
合同条款可以是明示或默示的。明示条款是明确约定的；默示条款由成文法（如货物销售法）或法院为赋予商业效力而添加。
t of the contract. Breach of a condition entitles the innocent party to repudiate the contract and claim damages.
条件条款 = 触及合同根基的条款。违反条件条款使无过错方有权终止合同并索赔。
ral to the main purpose. Breach of a warranty entitles the innocent party to damages only, not repudiation.
保证条款 = 较次要的条款，附属于主要目的。违反保证条款仅使无过错方有权索赔，无权终止合同。
Innominate term approach – the court looks at the effect of the breach. If it substantially deprives the innocent party of the whole benefit, it is treated as a condition; otherwise, it is treated as a warranty.
中间条款认定法——法庭考察违约后果。若实质上剥夺了无过错方的全部利益，则作条件条款处理；否则作保证条款处理。
Remedies for breach: Damages aim to put the claimant in the position they would have been in had the contract been performed. Equitable remedies such as specific performance and injunction are available at the court's discretion.
违约救济：损害赔偿旨在使原告处于合同如被履行本应处的境地。衡平法救济如强制履行和禁制令由法院酌情授予。
11. Damages Calculation Principles | 损害赔偿计算原则
ges (non-monetary losses) + Special damages (quantifiable monetary losses). The aim is restitutio in integrum – to restore the claimant to their pre-tort or pre-breach position.
补偿性损害赔偿 = 一般损害赔偿（非金钱损失）+ 特殊损害赔偿（可量化的金钱损失）。目标是 restitutio in integrum——使原告恢复至侵权前或违约前状态。
In tort, general damages include pain, suffering and loss of amenity (PSLA). Special damages cover lost earnings, medical expenses and other financial losses incurred up to the trial date.
在侵权中，一般损害赔偿包括疼痛、痛苦和生活乐趣丧失 (PSLA)。特殊损害赔偿涵盖截至审判日期已产生的收入损失、医疗费用和其他财务损失。
In contract, the claimant can recover loss of bargain (expectation loss) and reliance loss, but must take reasonable steps to mitigate their loss. Remote loss that was not within the reasonable contemplation of the parties is not recoverable.
在合同中，原告可追讨交易损失（期待利益损失）和信赖损失，但必须采取合理措施减损。当事人合理考虑范围之外的遥远损失不可追偿。
Contributory negligence reduces the claimant's damages by the percentage their own fault contributed to the injury. In contract, the principle also applies under the Law Reform (Contributory Negligence) Act 1945 where there is concurrent liability in tort.
共同过失按原告自身过错对伤害的促成比例扣减损害赔偿。在合同中，若存在侵权法上的并存责任，该原则也依 1945 年法律改革（共同过失）法令适用。
12. Sentencing and Mitigation Factors | 量刑与减轻因素
When passing sentence, the court considers: Aggravating factors – previous convictions, offence committed on bail, use of a weapon, targeting a vulnerable victim. Mitigating factors – genuine remorse, early guilty plea, minor role in the offence, personal circumstances.
法庭量刑时考虑：加重因素——前科、保释期间犯罪、使用武器、针对弱势受害者。减轻因素——真诚悔过、及早认罪、在犯罪中起次要作用、个人情况。
A guilty plea can reduce the sentence. The earlier the plea, the greater the reduction: maximum reduction is usually one-third if pleaded at the first reasonable opportunity.
认罪可减轻刑罚。认罪越早，减幅越大：若在最早合理时机认罪，通常可获最多三分之一减让。
The aims of sentencing are: punishment of offenders, reduction of crime (including by deterrence), reform and rehabilitation of offenders, protection of the public, and reparation to victims.
量刑目的包括：惩罚罪犯、减少犯罪（含威慑）、改造和更生罪犯、保护公众以及向受害者作出补偿。
For adult offenders, custodial sentences, community orders and fines may be imposed. For youths, referral orders, youth rehabilitation orders and detention are the main options.
对成年罪犯，可处监禁刑、社区令和罚金。对青少年，主要选项为转介令、青少年更生令和羁留。
