The Premier of the Western Cape challenged the constitutional validity of certain provisions of the Public Service Laws Amendment Act 86 of 1998, which amended the Public Service Act 103 of 1994. The amendments formed part of a national legislative scheme restructuring the public service by redefining provincial departments, altering reporting lines, and reallocating administrative powers between provincial Directors-General, heads of departments, provincial Executives, the President, and the Minister for Public Service and Administration. The Western Cape government contended that these changes impermissibly infringed provincial executive authority and autonomy by prescribing how provincial administrations must be structured. The dispute, being between organs of state in the national and provincial spheres concerning constitutional powers, fell within the exclusive jurisdiction of the Constitutional Court.
