Mr Sithembiso Siphelele Mkhize was employed as a warder by the Department of Correctional Services. In January 2008 he was dismissed after a disciplinary enquiry for allegedly bringing dagga into a prison. The dismissal was upheld as procedurally and substantively fair by an arbitrator of the General Public Services Sectoral Bargaining Council. Mr Mkhize’s review application to the Labour Court was dismissed, and the Labour Appeal Court refused leave to appeal. On further appeal to the Supreme Court of Appeal, Mr Mkhize sought to introduce new evidence in the form of an affidavit by a fellow warder, Mr Gilbert Sibiya, who admitted that he had falsely implicated Mr Mkhize out of personal animosity and that a prisoner had planted the dagga. This evidence had not been available during the arbitration or review proceedings.
