The President of the Republic of South Africa and Others v United Democratic Movement

South Africa's electoral system is based on proportional representation at national, provincial, and local government levels. The interim Constitution (Act 200 of 1993) contained anti-defection provisions requiring members of the National Assembly and provincial legislatures to vacate their seats if they ceased to be members of the party that nominated them. The 1996 Constitution did not contain such anti-defection provisions in its main text, but Schedule 6 (transitional provisions) maintained the anti-defection provisions until the second election under the new Constitution. On 19 June 2002, the President signed into law four Acts of Parliament that suspended the anti-defection provisions during specified "window periods" to allow members to defect from their parties without losing their seats. The United Democratic Movement (UDM), a political party represented in the National Assembly and some provincial legislatures and municipal councils, challenged the constitutionality of this legislation. On 20 June 2002, at 19h00, the UDM brought an urgent application in the Cape High Court seeking to suspend the commencement of the four Acts. Nel J granted an interim order suspending commencement pending a Full Court hearing. On 24 June 2002, the Full Court granted an order suspending the commencement and/or operation of the legislation pending a Constitutional Court application by 27 June 2002. Neither court provided reasons for their orders. The government appellants opposed the relief and appealed to the Constitutional Court, arguing the High Court lacked jurisdiction to suspend Acts of Parliament.

• Whether the High Court has jurisdiction to grant interim relief suspending the commencement or operation of Acts of Parliament
• Whether the High Court's jurisdiction differs when the impugned legislation is a constitutional amendment
• Whether the interests of justice required the grant of interim relief in this case
• The proper interpretation of sections 80, 122, 167(4), 167(5), and 172(2) of the Constitution regarding exclusive jurisdiction of the Constitutional Court
• The balance between legislative supremacy within a constitutional framework and judicial authority to protect constitutional rights
• Whether interim relief should have been tailored to be less invasive of legislative functions

The appeal was upheld and the order of the High Court was set aside. Each party was ordered to pay its own costs.

The binding legal principles established are: (1) It is unnecessary to decide definitively whether a High Court has jurisdiction to grant interim relief suspending the operation of national or provincial legislation; (2) A High Court does have jurisdiction to grant interim relief designed to maintain the status quo or prevent violation of constitutional rights where legislation alleged to be unconstitutional, through itself or through feared actions, might cause irreparable harm of a serious nature; (3) Such interim relief should only be granted where strictly necessary in the interests of justice, applying the constitutional standard in sections 80(3) and 122(3); (4) In determining the interests of justice, courts must balance the interests of the person seeking relief against the interests of others who might be affected; (5) Interim relief should be strictly tailored to interfere as little as possible with the operation of legislation, especially where it relates to constitutional amendments; (6) An applicant for such relief must demonstrate manifest prejudice or prejudice established on the facts; (7) No court may consider the constitutionality of a bill before the National Assembly or provincial legislature except as provided in sections 79 and 121 of the Constitution.

The Court made several important obiter observations: (1) The Court noted that the question whether the High Court has power to grant interim relief to prevent a constitutional amendment from coming into operation (section 167(4)(d)) or where Parliament or the President has failed to fulfill a constitutional obligation (section 167(4)(e)) gives rise to special constitutional considerations that need not be decided in this case; (2) The Court observed that the omission from the 1996 Constitution of a provision equivalent to section 101(7) of the interim Constitution (which expressly permitted High Courts to grant interdicts suspending Acts of Parliament) is relevant to interpreting the High Court's jurisdiction; (3) The Court commented that the Constitutional Court is not designed to act in matters of extreme urgency, noting its composition of eleven members, quorum requirements of eight, and recess periods when members disperse to distant homes, making it difficult to convene at very short notice; (4) The Court emphasized that having regard to the importance of the legislature in a democracy and the deference to which it is entitled, courts should not interfere with legislative will unless absolutely necessary to avoid likely irreparable harm; (5) The Court noted that where legislation amends the Constitution and has achieved special support required by the Constitution, courts should be even more cautious not to thwart the legislative will except in extreme cases; (6) The Court observed that the purpose of provisions conferring exclusive jurisdiction on the Constitutional Court for certain matters is "to preserve the comity between the judicial branch of government, on the one hand, and the legislative and executive branches of government, on the other, by ensuring that only the highest Court in constitutional matters intrudes into the domains of the principal legislative and executive organs of State" (citing SARFU).

This case is significant in South African constitutional law as it clarifies the jurisdiction of the High Court to grant interim relief in matters where the Constitutional Court has exclusive jurisdiction, particularly regarding challenges to Acts of Parliament and constitutional amendments. The judgment establishes important principles regarding the separation of powers and the relationship between the judiciary and the legislature in South Africa's constitutional democracy. It confirms that while courts must uphold constitutional supremacy, they must also respect the special democratic mandate of the legislature and only interfere with legislation when strictly necessary to prevent irreparable harm. The case provides guidance on when and how interim relief may be granted against legislation, requiring applicants to demonstrate manifest prejudice and courts to tailor relief to be minimally invasive. The judgment balances constitutional values of legislative accountability and responsiveness with judicial authority to protect constitutional rights. It also addresses the practical challenges of the Constitutional Court's structure and recess periods, acknowledging the need for accessible interim relief mechanisms while maintaining appropriate deference to the legislature.
