Separation of Powers
Introduction
The separation of powers is a foundational principle of the South African constitutional order. The Constitution of the Republic of South Africa, 1996, establishes three branches of government: the legislature (Parliament and provincial legislatures), the executive (the President, Cabinet, and provincial executives), and the judiciary (the courts). While the Constitution does not expressly use the term “separation of powers,” the principle is implicit in its structure and has been affirmed by the Constitutional Court.
Constitutional Framework
The Constitution establishes the three branches of government in separate chapters. Chapter 4 establishes Parliament, Chapter 5 establishes the President and the National Executive, Chapter 6 establishes the provinces, Chapter 7 establishes local government, and Chapter 8 establishes the courts and the administration of justice. Each branch has distinct powers and functions, but the Constitution also provides for checks and balances.
The Legislature
Parliament consists of the National Assembly and the National Council of Provinces (NCOP). The National Assembly is elected by proportional representation and is responsible for passing legislation, scrutinising the executive, and holding the President accountable. The NCOP represents the provinces and participates in the legislative process.
The Executive
The President is the Head of State and Head of the National Executive, elected by the National Assembly from among its members. The President appoints the Deputy President and Ministers from among the members of the National Assembly. The executive is responsible for implementing legislation, developing policy, and conducting the administration of the state.
The Judiciary
The judiciary is independent, subject only to the Constitution and the law. Courts have the power to review the constitutionality of legislation and executive conduct. The Constitutional Court is the highest court in all constitutional matters and has the power to declare legislation invalid.
Checks and Balances
The Constitution provides for checks and balances among the three branches. The legislature may hold the executive accountable through questions, oversight committees, and impeachment (section 89). The executive may refer bills back to Parliament or to the Constitutional Court for a decision on constitutionality. The judiciary may review legislation and executive conduct for constitutional compliance.
Judicial Application
The Constitutional Court has addressed the separation of powers in several important cases. In Executive Council of the Western Cape Legislature v President of the RSA 1995 (4) SA 877 (CC), the Court held that the separation of powers requires that each branch respect the functional independence of the others. In South African Association of Personal Injury Lawyers v Heath 2001 (1) SA 883 (CC), the Court set limits on the delegation of judicial power.
Conclusion
The separation of powers is a central feature of South African constitutionalism, ensuring that power is distributed and checked. The Constitution’s careful allocation of powers among the three branches, combined with robust checks and balances, reflects a commitment to preventing the abuse of power and protecting democratic governance.
