Law Study Guide

📖 Core Concepts Law – A set of rules created and enforced by governmental or societal institutions to regulate behavior. Public vs. Private Law – Public law governs the state‑society relationship (constitutional, administrative, criminal). Private law governs relationships between individuals (contracts, torts, property). Legal Systems – Broadly classified as civil law (codified statutes), common law (judge‑made precedent), and religious law (e.g., Sharia). Legal Positivism vs. Natural Law – Positivism: law is “is” (rules of a sovereign) independent of morality. Natural law: law reflects immutable moral principles. Separation of Powers – Division of authority among legislature, executive, and judiciary to prevent concentration of power. Doctrine of Precedent (Stare Decisis) – In common law, lower courts must follow higher‑court decisions. Criminal Liability Elements – Actus reus (guilty act) + mens rea (guilty mind). Strict‑liability crimes need only actus reus. Contract Formation (Common‑law) – Offer, acceptance, consideration, and intention to create legal relations. Negligence (Tort) – Duty of care, breach, causation, damages (Donoghue v Stevenson). Trust – Legal ownership held by trustees; beneficial ownership held by beneficiaries; fiduciary duties apply. --- 📌 Must Remember Hart’s definition: law = “system of rules”. Austin’s command theory: law = command of a sovereign backed by sanctions. Kelsen’s Grundnorm: a basic norm that gives legitimacy to the legal order. Stare decisis → stability & predictability in common law. Rechtsstaat – Everyone, including the government, is subject to the law. Actus reus + mens rea → crime (unless strict liability). Consideration → essential for enforceable common‑law contracts; not required in civil‑law contracts. Four elements of negligence: duty, breach, causation, harm. International law sources: treaties, customary law, general principles, judicial decisions. Max Weber: state holds monopoly on legitimate force; legal rationality = rule by abstract norms. --- 🔄 Key Processes Legislative Process (Bicameral) Draft → First reading → Committee → Second reading → Amendments → Third reading → Vote in each house → Passage → Royal/Presidential assent. Judicial Precedent Creation (Common Law) Fact pattern → Application of existing rule → Reasoned judgment → Publication → Becomes binding precedent (stare decisis). Statutory Interpretation (Four Methods) Linguistic → plain meaning. Teleological → purpose/goal. Systemic → fit within whole legal system. Apply golden rule (avoid absurdity) or mischief rule (cure the problem the statute intended). Criminal Procedure (Investigation → Trial) Investigation (police) → Arrest → Charging (prosecutor) → Pre‑trial motions → Jury trial (facts) → Verdict → Sentencing. --- 🔍 Key Comparisons Civil Law vs. Common Law – Codified statutes vs. judge‑made precedent. Natural Law vs. Legal Positivism – Morality‑based vs. rule‑based, sovereign authority. Public Law vs. Private Law – State‑centered vs. individual‑centered. Consideration (Common Law) vs. No Consideration (Civil Law) – Must be present vs. not required. Strict Liability vs. Mens Rea Crimes – Liability without fault vs. requires guilty mind. --- ⚠️ Common Misunderstandings “All laws are moral” – Confuses natural law with legal positivism; many statutes are neutral to morality. “Precedent can be ignored in civil law” – Civil‑law judges may consult prior decisions for guidance, but they are not binding. “Mens rea is always required” – Strict‑liability offences waive the mens rea element. “Consideration equals fairness” – Consideration is a formal requirement, not a substantive fairness test. “International law is enforced like domestic law” – It relies on state consent; enforcement mechanisms are limited. --- 🧠 Mental Models / Intuition Law as a “traffic system” – Rules (signs) guide behavior; enforcement (police) ensures compliance; courts are the “accident investigators” interpreting signals when disputes arise. “Layers of authority” – Think of the state as a layered cake: Constitution (top), statutes, regulations, case law (bottom). Each layer must be consistent with the one above. “Precedent as a river” – Water (law) flows downstream; upstream decisions shape the current flow, but a major “dam” (legislative amendment) can reroute it. --- 🚩 Exceptions & Edge Cases Statutory exceptions – Mis‑statement of law, retroactive provisions, or explicit derogations from general rules. Equity overrides – In common law, equitable remedies (e.g., injunctions) can supersede strict legal rights when fairness demands. Diplomatic immunity – International law exception to criminal jurisdiction. Non‑justiciable political questions – Courts may decline to rule on matters deemed “political” (e.g., certain foreign policy decisions). --- 📍 When to Use Which Interpretation Method: Use linguistic when the text is clear. Switch to teleological if plain meaning leads to absurd results. Apply systemic for ambiguous provisions that must fit the broader legal framework. Choosing Legal System Analysis: For contract disputes in Europe → focus on civil‑law codifications. For tort claims in the U.S. → rely on common‑law precedent and the duty of care test. When to invoke International Law: When a dispute involves state‑to‑state relations, human rights, or cross‑border crimes and there is an applicable treaty or customary rule. --- 👀 Patterns to Recognize “Duty → Breach → Causation → Damage” pattern signals a negligence claim. “Statute + Purpose + Context” pattern signals the need for teleological interpretation. “Sovereign command + sanction” phrasing points to Austin’s command theory (positivist analysis). “Codified sections + no precedent cited” indicates a civil‑law jurisdiction. --- 🗂️ Exam Traps Distractor: “All legal systems treat precedent the same.” – Wrong; civil law does not bind future cases to past decisions. Near‑miss: “Consideration is required for any enforceable contract.” – Only true in common‑law systems; civil law does not require it. Misleading choice: “Strict liability always requires proof of negligence.” – Contradicts the definition of strict liability. Trap: “International law can be enforced by any national court without consent.” – Incorrect; enforcement depends on state consent and treaty mechanisms. Red herring: “The executive creates law.” – The executive proposes and enforces; only the legislature enacts statutes (except common‑law judge‑made law).
