During the 2007 national public service strike, members of the Police and Prisons Civil Rights Union (POPCRU), including employees of the South African Police Service (SAPS), intended to participate in strike action. SAPS employees fall into two categories: members appointed under the South African Police Service Act 68 of 1995 (SAPS Act), and non-member personnel employed under the Public Service Act 103 of 1994 (PSA) who perform support functions. SAPS approached the Labour Court to interdict POPCRU members from striking, contending that all SAPS employees render an essential service under the Labour Relations Act 66 of 1995 (LRA) and are therefore prohibited from striking. The Labour Court, and subsequently the Labour Appeal Court, held that only SAPS members (as defined in the SAPS Act) are engaged in an essential service, and that PSA-employed non-members are not. SAPS sought leave to appeal to the Constitutional Court.
