Summary of Classification of Law

## Introduction Legal classification helps students see how different areas of law relate and how rules are organised. There is no single perfect system, but useful classifications give a clear overview of major divisions such as international vs national law and substantive vs procedural law. > **Definition:** Legal classification is the organisation of legal rules into categories that reflect their source, purpose, or function within a legal system. ## 1. International law vs National law ### What is International Law? > **Definition:** International law consists of rules that govern relations between independent states and other international actors, often created by treaties, conventions, or customary practice. - Created by treaties (bilateral or multilateral) and customary international law - Applies between states and sometimes to international organisations and individuals (in limited contexts) - Examples: treaties on human rights, laws of war, trade agreements Practical example: Two states negotiate a bilateral trade treaty that sets tariffs and dispute-resolution rules. That treaty becomes an international legal commitment between them. Did you know that section 39(1) of the South African Constitution requires courts to consider international law when interpreting the Bill of Rights? This makes international law a formal interpretive tool in national constitutional adjudication. > **Why this matters in practice:** Courts may rely on international law to interpret domestic rights and obligations; international agreements can influence national legislation. ### What is National (Domestic) Law? > **Definition:** National law is the body of rules that applies and is enforced within a particular state. - Governs individuals, organisations and the state within a country - Includes constitutions, statutes, regulations, common law and customary law - Example: criminal codes, contract law, property law as enforced by national courts ## 2. Substantive Law vs Procedural Law ### Substantive Law (Material Law) > **Definition:** Substantive law defines rights, duties and the substantive content of legal rules (what conduct is regulated and what consequences follow). - Determines what conduct amounts to an offence (e.g., elements of theft) or what rights exist (e.g., ownership of property) - Examples: elements of a crime, rules for acquiring ownership of a motor vehicle, contract formation rules Practical example: Substantive law tells you that taking someone else's car without consent is theft and sets out the required elements to prove that offence. ### Procedural Law (Formal Law) > **Definition:** Procedural law prescribes the process and steps by which substantive rights and duties are enforced in courts and other forums. - Governs how cases are started, how evidence is admitted, how trials are conducted, bail procedures and appeal routes - Examples: criminal procedure, civil procedure, rules on service of process Practical example: Procedural law tells prosecutors how to lay charges, the accused’s right to bail, and how trials must be conducted so that the substantive prohibition (theft) can be enforced fairly. Did you know that without procedural rules to resolve disputes people are more likely to use force or self-help to enforce rights, which undermines the rule of law? ### How substantive and procedural law work together - Substantive law defines the legal claim; procedural law explains how to bring and decide the claim - Both are necessary: substantive rules without procedure cannot be enforced; procedure without substantive content serves no legal purpose ## 3. Divisions of Procedural Law | Area | Focus | Examples | |---|---:|---| | Criminal Procedure | How suspects are prosecuted and tried | Charging, bail, plea, trial process, sentencing | | Civil Procedure | How civil disputes are resolved in courts | Service of summons, pleadings, evidence rules, remedies | Bullet points for criminal procedu
