De Kock NO v Van Rooyen and Others

The respondent, Thomas Frederick van Rooyen, was convicted in the Pretoria Regional Court in 1997 of housebreaking with intent to steal and theft, and sentenced to six years’ imprisonment. The presiding regional magistrate, Mr Michiel de Kock, had retired and was re‑appointed in an acting capacity under a contract that could be terminated by the State on 14 days’ notice. Van Rooyen instituted review proceedings in the Pretoria High Court, contending that the magistrate’s insecure, contract-based appointment compromised judicial independence and rendered the trial a nullity. The High Court agreed and set aside the conviction and sentence as null and void. The Director of Public Prosecutions, the Minister of Justice and Constitutional Development, and the magistrate appealed to the Supreme Court of Appeal.

The appeal was upheld. The order of the High Court declaring the criminal proceedings null and void was set aside, and the review application was dismissed.

The case clarifies the effect of suspended declarations of constitutional invalidity on past and pending criminal proceedings. It reinforces that unconstitutional defects in judicial appointments do not automatically invalidate prior decisions where the Constitutional Court has limited or suspended the retrospective effect of invalidity. The judgment also strongly affirms the obligation of lower courts to apply Constitutional Court decisions fully, including their remedial aspects, thereby promoting certainty and coherence in South African constitutional jurisprudence.
