The appellants were long-term prisoners convicted of serious violent crimes and serving lengthy sentences in Pretoria Maximum Prison. On 13 November 1997 they were classified as A‑category prisoners, entitling them to substantial privileges. Without prior notice or an opportunity to be heard, they were transferred on 27 November 1997 to the C‑Max (Closed Maximum Security Unit), a special maximum‑security section with significantly harsher conditions and far fewer privileges. The transfer decision was taken by a deputy director acting under delegated authority, on the basis that the appellants posed a high escape risk due to alleged prior escape attempts. Four days after the transfer, the decision‑maker visited them and informed them of the reason for the transfer. The appellants challenged the lawfulness of the transfer, arguing that the decision was procedurally unfair because the audi alteram partem rule had not been observed.
