Although not a judicial precedent, the Act is significant in South African public administration law because it strengthens ethical controls over public employees, especially by broadening the prohibition on doing business with organs of state and creating a post-procurement cooling-off restriction. It also deepens integration across spheres of government by regulating transfers between the public service and municipalities, formalises the National School of Government as a national department, and centralises oversight over remuneration disparities and service conditions with financial implications. The amendments are important for governance, anti-corruption, labour relations in the public sector, and intergovernmental administration.
