Summary of South African Constitutional Law: Core Principles
South African Constitutional Law: Core Principles Explained
Introduction
The South African Constitution is the supreme law that structures government, limits state power, and embeds core values that guide the country. This study material explains the role and function of constitutional law in South Africa, contrasts the pre-1994 legal landscape with post-1994 constitutional supremacy, and unpacks key constitutional principles such as cooperative government, separation of powers, checks and balances, rule of law, democracy, and transformative constitutionalism. It also summarizes the Chapter 9 institutions that strengthen democracy.
Definition: Constitutional law is the body of legal rules, doctrines and practices that govern the operation of the state, determine which institutions have governing powers, delimit state powers and contain the supreme law of the country.
1. The importance and function of constitutional law in South Africa
- Constitutional law gives the framework for how public power is organised and exercised.
- It sets values that guide interpretation and governance, notably dignity, equality and freedom.
- It regulates the structure and functioning of the State, including which institutions have authority and how powers are shared between them.
- It contains the Bill of Rights and places obligations on the state to respect, protect and fulfil constitutional duties.
- It is the supreme law: any law or conduct inconsistent with the Constitution is invalid.
Practical example: A minister’s policy that exceeds statutory authority can be declared invalid by a court because it conflicts with constitutional allocations of executive power.
2. South African legal landscape before 1994: Parliamentary supremacy
Definition: Parliamentary supremacy (sovereignty) is the doctrine that Parliament is the ultimate legal authority and may make or change any law, including the constitution.
- Under parliamentary supremacy:
- Parliament was sovereign and could make or amend any law.
- The written constitution was often a procedural text setting out state structure but did not trump ordinary legislation.
- Courts could not invalidate Acts of Parliament on constitutional grounds in the way they can now.
Practical example: Pre-1994, the legislature could pass laws limiting rights or changing governance arrangements without being subject to constitutional review by the courts.
3. Parliamentary supremacy vs Constitutional supremacy
| Feature | Parliamentary supremacy | Constitutional supremacy |
|---|---|---|
| Source of ultimate authority | Parliament | Constitution |
| Can courts invalidate legislation? | Generally no | Yes, if inconsistent with the Constitution |
| Amending the constitution | Parliament alone (often) | Subject to constitutional entrenchment and amendment procedures |
| Protection of rights | Limited by Parliament | Rights are enforced and protected by judiciary |
- Under constitutional supremacy the Constitution is the highest source of authority; all statutes and executive actions must comply with it.
- South Africa’s post-1994 Constitution embraces constitutional supremacy and judicial review.
4. Cooperative government
Definition: Cooperative government is a constitutional principle requiring all spheres of government and state organs to work together in mutual trust and good faith.
- Found in Chapter 3 of the Constitution.
- Requires intergovernmental co-operation and non-intrusion into the geographic, functional or institutional integrity of another sphere of government.
- Promotes coordination in policy, service delivery and resource use.
Practical example: A provincial
