In a landmark decision on 17 September 2026 the Constitutional Court of South Africa declared the Public Procurement Act (PPA) unconstitutional in its entirety. The ruling stemmed from consolidated cases brought by the Premier of the Western Cape, the City of Cape Town, and civil-society organisations that argued the Bill's public-participation process was defective.
The Court's judgment, written by Justice Nuku, held that Parliament failed to comply with the Constitution's public-participation provisions (Sections 59(1)(a) and 72(1)(a)). The Court found that the legislative process was hurried: stakeholders received only a short notice period, limited time to prepare written comments, and brief public hearings. The Court rejected the argument that a summary of submissions by the Treasury could substitute for genuine parliamentary scrutiny.
Legally, the decision affirms that public participation is a substantive constitutional requirement, not a mere formality. It means that any future legislation must provide adequate time, clear communication, and genuine consideration of public input, or risk being struck down. For the procurement sector, the ruling invalidates a law that had been expected to overhaul how the state buys goods and services, potentially affecting all public-sector contracts.
The judgment will force Parliament to revise the PPA to meet constitutional standards and may open the door for other legislation that failed to satisfy the participation criteria to be challenged. The ruling underscores the role of the courts in safeguarding democratic accountability and ensuring that the public has a real voice in law-making.
