Legal history Study Guide

📖 Core Concepts Legal history – the study of how law changes over time and why; it sits inside the broader sweep of social history. Historiographical shift – early jurists merely recorded statutes; 20th‑century scholars view legal institutions as complex systems of rules, actors, and symbols. Casuistic law – “if … then …” conditional statements, the logical form of the earliest codes (Ur‑Nammu, Hammurabi). Civil‑law tradition – codified statutes (e.g., Napoleonic Code, German BGB) that aim for completeness and logical organization. Common‑law tradition – law grows from judicial decisions (precedent) rather than exhaustive statutes. Key ancient traditions – Sumerian code (22nd c BC), Babylonian Code of Hammurabi (1760 BC), Greek distinctions (thémis, nómos, díkē). Roman law – foundation of many modern systems; key features: lay iudex, Justinian’s Corpus Juris Civilis (6th c AD). Islamic law – legal system rooted in religious doctrine; classical period produced major jurisprudential institutions. Modern convergence – EU law blends codified treaties with Court of Justice precedent, illustrating civil‑law ↔ common‑law interaction. --- 📌 Must Remember Ur‑Nammu – first extant code, ca. 22nd c BC, casuistic style. Codex Hammurabi – stone‑displayed Babylonian law, 1760 BC. Greek law terms – thémis (divine), nómos (human decree), díkē (custom). Justinian’s Corpus Juris Civilis – reduced Roman law to 1/20 of prior material (6th c AD). Henry II’s Assize of Clarendon (1166) – created royal courts & jury trials; ended trial‑by‑combat. Louis IX (1223) – imported canon‑law inquisitorial procedures into French royal courts. Napoleonic Code (1804) & German BGB (1900) – model civil‑law codes worldwide. U.S. common‑law foundation – derived from English common law; Louisiana = civil‑law exception. EU legal duality – treaties (codified) + ECJ precedent (case law). --- 🔄 Key Processes Early codification (casuistic) Identify recurring disputes → formulate “if X then Y” rule → inscribe on stone/tablet. Roman legal evolution iudex (lay adjudicator) → professional jurists → Justinian’s systematic codification → transmission to medieval scholars (Bologna). Common‑law formation (England) Royal judges record decisions → develop stare decisis (binding precedent) → expand through case law. Civil‑law codification Draft comprehensive code → systematic arrangement (persons, property, obligations) → legislative enactment → periodic revision. Modern EU integration Adopt treaty text → ECJ interprets → precedent shapes future treaty application → gradual convergence with civil‑law reasoning. --- 🔍 Key Comparisons Civil law vs. Common law Source: codified statutes vs. judicial precedent. Role of judges: apply code literally vs. create law through interpretation. Divine law (Greek thémis) vs. Human decree (nómos) Origin: gods/ cosmic order vs. human legislative authority. Roman iudex vs. Modern judge Status: layperson selected ad hoc vs. professional, trained magistrate. Islamic law vs. Confucian legal tradition Basis: religious doctrine vs. moral conduct and social harmony. --- ⚠️ Common Misunderstandings “Civil law has no case law.” – Civil courts still rely on jurisprudence for interpretation. “Common law equals only England/USA.” – Many former colonies (e.g., Malaysia, Singapore) retain common‑law foundations. “Justinian erased all earlier Roman law.” – He reduced and organized it; many concepts survived. “Islamic law is monolithic.” – Diverse schools (Hanafi, Shafi‘i, etc.) and local customs shape practice. “African customary law is static.” – It adapts continuously to social change. --- 🧠 Mental Models / Intuition Layered cake model – Legal systems are built in layers: ancient customs → codified statutes → judicial interpretation → modern reforms. If‑then tree – Early codes resemble decision trees; think of each “if” as a branch leading to a prescribed “then.” Roadmap of convergence – Picture EU law as a hybrid car: the engine (treaties) runs on fuel (codified rules) while the GPS (ECJ precedent) directs the route. --- 🚩 Exceptions & Edge Cases Louisiana – Civil‑law system within a predominantly common‑law nation (U.S.). Soviet socialist law in early PRC – Emphasized administrative control over private‑law rights. Sharia introduction in India – Co‑existed with Hindu and British common law; not uniformly applied. EU law – Treaties codified, but ECJ precedent creates a common‑law‑like dynamic. --- 📍 When to Use Which Answering a “source of law” question – Cite statutes for civil‑law jurisdictions; cite case law for common‑law jurisdictions. Analyzing a historical legal reform – Use the “centralization → decentralization” pattern (e.g., Charlemagne vs. post‑Roman folk‑right). Comparing legal traditions – Apply the “origin of authority” test: religious doctrine (Islamic), moral philosophy (Confucian), legislative act (civil). Choosing a precedent vs. code – If the problem references statutory language or a civil‑law jurisdiction → start with the code; if it references case citations or common‑law jurisdiction → begin with precedent. --- 👀 Patterns to Recognize Casuistic “if‑then” language → signals ancient code (Ur‑Nammu, Hammurabi). Centralized legal reform → later fragmentation → Charlemagne’s law → feudal customary law. Legal transplantation → Japan’s import of French/German codes; British common law in former colonies. Hybrid legal environments → EU law, Louisiana, modern China (civil code + socialist influence). --- 🗂️ Exam Traps Distractor: “All Asian legal systems are common law.” – Wrong; Japan adopted civil codes, India shifted from Hindu/Islamic to common law under British rule. Distractor: “The Assize of Clarendon abolished juries.” – Actually introduced juries and reduced trial‑by‑combat. Distractor: “Louis IX made all French law inquisitorial.” – He extended canon‑law procedures only to royal courts, not the whole system. Distractor: “EU law is purely codified.” – Treaties are codified, but ECJ case law creates a precedent‑driven dimension. Distractor: “Justinian eliminated all earlier Roman statutes.” – He compiled and reduced them, preserving many core principles. ---
