1. The Criminal Liability Formula | 刑事责任公式
In Scots criminal law, establishing guilt typically requires two elements: the guilty act (actus reus) and the guilty mind (mens rea). These must coincide in time and be proven beyond reasonable doubt. A third element – the absence of a valid defence – confirms liability. Thus, the fundamental criminal equation is:
Actus Reus + Mens Rea – Defence = Criminal Liability
在苏格兰刑法中，确立罪名通常需要两个要件：犯罪行为（actus reus）和犯罪意图（mens rea）。二者须在时间上同时存在，且须经排除合理怀疑证明。第三个要素——不存在有效抗辩——最终确认责任。因此，基本的刑事公式为：
犯罪行为 + 犯罪意图 - 抗辩 = 刑事责任
Actus reus includes both actions and, in some cases, omissions where a duty of care exists. Mens rea ranges from intention to recklessness. Common defences include self-defence, mental disorder, and duress.
犯罪行为既包括积极作为，在某些存在照管义务的情况下也包括不作为。犯罪意图从故意到轻率不等。常见抗辩包括正当防卫、精神障碍和胁迫。
2. Negligence Formula (Civil Law) | 过失责任公式（民法）
To succeed in a claim for negligence under Scots delict law, the pursuer must establish four elements: a duty of care owed by the defender, a breach of that duty, a causal link between the breach and the harm, and actual damage or loss. This can be expressed as:
Duty + Breach + Causation + Damage = Negligence
根据苏格兰侵权法，原告要成功提起过失诉讼必须确立四项要素：被告负有注意义务、被告违反了该义务、违反行为与损害之间存在因果关系，以及实际损害或损失。可表示为：
注意义务 + 违反义务 + 因果关系 + 损害 = 过失责任
The court uses the tripartite test: foreseeability of harm, proximity between parties, and whether it is fair, just and reasonable to impose a duty.
法院采用三部分检验标准：损害的可预见性、当事人之间的近邻关系，以及施加义务是否公平、正当、合理。
3. Contract Formation Equation | 合同成立公式
A legally binding contract in Scots law requires four ingredients: offer, acceptance, consideration, and an intention to create legal relations. Without any one of these, the agreement may be unenforceable. The equation reads:
Offer + Acceptance + Consideration + Intention = Contract
苏格兰法律下，一份具有法律约束力的合同需要四个要素：要约、承诺、对价以及设立法律关系的意图。缺少任何一个，协议都可能无法执行。公式为：
要约 + 承诺 + 对价 + 设立法律关系的意图 = 合同
An offer must be distinguished from an invitation to treat, such as goods displayed on a shelf, which is merely an invitation for customers to make an offer.
要约必须与要约邀请区分开，例如货架上的商品陈列仅属于要约邀请，邀请顾客提出要约。
4. Murder vs Culpable Homicide Formula | 谋杀与过失杀人公式
In Scots law, murder is committed when a person unlawfully kills another human being with malice aforethought – either an intention to kill or wicked recklessness. Culpable homicide covers unlawful killings without such wicked intent. The rough formula:
Unlawful Killing + Human Being + Malice Aforethought = Murder
Unlawful Killing + Human Being – Malice Aforethought = Culpable Homicide
苏格兰法律中，构成谋杀须非法杀害他人，并且具有恶意预谋——即杀人意图或邪恶的轻率。过失杀人则指没有这种邪恶意图的非法杀害行为。粗略公式为：
非法杀害 + 被害人 + 恶意预谋 = 谋杀
非法杀害 + 被害人 - 恶意预谋 = 过失杀人
5. Theft and Dishonesty Formula | 盗窃与不诚实行为公式
Theft under Scots common law is the dishonest appropriation of property belonging to another with the intention to permanently deprive the owner of that property. The equation captures this:
:Dishonest Appropriation + Property + Belonging to Another + Intention to Permanently Deprive = Theft
苏格兰普通法下的盗窃是指以永久剥夺所有者为目的，不诚实地侵占他人财产。该公式概括如下：
不诚实侵占 + 财产 + 归属他人 + 永久剥夺的意图 = 盗窃
Robbery adds the element of violence or threat of violence to theft. Embezzlement involves property lawfully in possession but then dishonestly used.
抢劫则在盗窃基础上增加了暴力或暴力威胁。侵占则是指合法占有的财产被不诚实使用。
6. Defences “Equation” | 抗辩“公式”
Even when actus reus and mens rea are present, criminal liability may be negated by a valid defence. Common defences include: self-defence (proportionate response to imminent attack), mental disorder (proving the accused did not appreciate the nature or wrongfulness of the act), duress (threat of death or serious harm), and necessity (choosing the lesser evil). The effect is:
Criminal Liability – Valid Defence = Acquittal
即使存在犯罪行为和犯罪意图，有效抗辩也可能排除刑事责任。常见抗辩包括：正当防卫（对迫近攻击的相称反应）、精神障碍（证明被告人未认识到行为性质或非法性）、胁迫（面临死亡或严重伤害的威胁）和紧急避险（两害相权取其轻）。其效果为：
刑事责任 - 有效抗辩 = 无罪释放
7. Burden and Standard of Proof | 举证责任与证明标准
The golden rule of evidence law is that “he who asserts must prove.” In criminal cases, the prosecution bears the legal burden of proving all elements of the offence. The standard is beyond reasonable doubt. In civil cases, the party making the claim must prove their case on the balance of probabilities. This can be summarised:
Prosecution (Criminal) → Prove All Elements Beyond Reasonable Doubt
Pursuer (Civil) → Prove Case on Balance of Probabilities
证据法的金科玉律是“谁主张、谁举证”。刑事案件中，控方承担证明犯罪所有要素的法定责任，证明标准是排除合理怀疑。民事案件中，索赔方必须依据优势证据标准证明其主张。可概括为：
控方（刑事）→ 就所有要素证明至排除合理怀疑
原告（民事）→ 以优势证据标准证明其案件
There are exceptions, such as the defence of diminished responsibility where the accused may have an evidential burden to raise the issue.
存在例外，如减轻责任抗辩，被告人可能负有提出争点的举证负担。
8. Statutory Interpretation Rules | 法律解释规则
When courts interpret statutes, they apply a set of “rules” – better seen as approaches. The Literal Rule gives words their ordinary dictionary meaning, even if the outcome seems harsh. The Golden Rule modifies this to avoid absurd results. The Mischief Rule looks at the gap or “mischief” the statute was designed to remedy and interprets accordingly. A simple formula:
Literal → Golden (if absurd) → Mischief (if parliament’s purpose clear)
法院解释成文法时，会运用一系列“规则”——更确切地说是方法。文义规则按词语的普通字典含义解释，即使结果显得严苛。黄金规则在避免荒谬结果时对文义规则作出变通。弊端规则审查法律旨在填补的漏洞或“弊端”，并依此解释。简易公式：
文义规则 → 黄金规则（如结果荒谬）→ 弊端规则（如议会意图明确）
The purposive approach, heavily influenced by EU law, goes further by seeking the overall purpose of the legislation.
受欧盟法重大影响的目的是以探求立法总体目的的解释方法。
9. Key Legal Maxims (Formula-Like Principles) | 核心法律格言（公式化原则）
Legal maxims are concise expressions of fundamental principles. Some operate as formulas:
“Ignorantia juris non excusat” = Ignorance of the law is no defence.
“Actus non facit reum nisi mens sit rea” = An act does not make a person guilty unless the mind is also guilty.
“Nemo dat quod non habet” = No one can give what they do not have (property law).
“Res ipsa loquitur” = The thing speaks for itself (used in negligence).
法律格言是对基本原则的精炼表达。一些格言如同公式：
“不知法不免责”= 不知晓法律不能成为抗辩理由。
“无犯意则无犯人”= 仅有行为不足以定罪，必须同时具有犯意。
“不能给付自己没有的东西”= 无人能转让自己不享有的权利（财产法）。
“事实自证”= 事情本身说明问题（用于过失诉讼）。
10. Judicial Precedent Equation | 司法先例公式
The doctrine of stare decisis means courts must follow higher courts’ rulings when the facts are similar. The ratio decidendi (reason for decision) is binding; obiter dicta (remarks by the way) are persuasive only. A simplified hierarchy:
rt (UK) → Court of Session (Inner House) → Sheriff Appeal Court → Sheriff Court (Scotland)
The equation: Binding Precedent = Higher Court Decision + Identical Material Facts
遵循先例原则意味着，当下级法院面对相似事实时，必须遵从上级法院的裁决。判决理由具有约束力；附带意见仅具说服力。苏格兰的简化层级为：
英国最高法院 → 高等民事法院（内庭）→ 郡上诉法院 → 郡法院
公式：约束性先例 = 上级法院判决 + 相同关键事实
11. Rights of Arrested Persons Formula | 被捕者权利公式
Under Scots law, upon arrest a person must be informed promptly of: the reason for arrest, the right to remain silent (though adverse inferences may be drawn in some situations), and the right to access a solicitor. The caution reads: “You do not have to say anything, but it may harm your defence if you do not mention when questioned something you later rely on in court.” The simplified rights package:
Arrest = Right to Reason + Right to Silence (with caution) + Right to a Solicitor
苏格兰法律规定，逮捕时必须即时告知被捕者：逮捕理由、有权保持沉默（但在某些情况下可能因沉默受到不利推断），以及有权聘请律师。警告词为：“你不必说任何话，但如果在被询问时未提及你此后在法庭上依赖的事项，这可能会损害你的辩护。”简化的权利包为：
逮捕 = 获知理由权 + 沉默权（附警告） + 律师权
12. The Law-Making Formula | 立法公式
In the Scottish legal system, law comes from multiple sources: legislation (Acts of the UK and Scottish Parliaments), common law (judge-made law through precedent), and European/human rights law. Devolution allows the Scottish Parliament to legislate on devolved matters. A basic hierarchy:
Primary Legislation > Secondary Legislation > Judicial Precedent (subject to compatibility with the Scotland Act 1998 and the Human Rights Act 1998).
在苏格兰法律体系中，法律来源包括多个方面：立法（英国议会和苏格兰议会的制定法）、普通法（通过先例形成的法官造法）以及欧洲/人权法。权力下放允许苏格兰议会在权力下放事项上立法。基本层级为：
一级立法 > 二级授权立法 > 司法先例（须符合《1998年苏格兰法》及《1998年人权法》）。
