Minister for Safety and Security v Van der Merwe and Others

SARS and the SAPS investigated the respondents for suspected tax offences, VAT fraud and money laundering. Search and seizure warrants were issued under sections 20 and 21 of the Criminal Procedure Act 51 of 1977 for various residential and business premises linked to the respondents. Although the supporting affidavits detailed the suspected offences, the warrants themselves did not specify the offences or the nature of the investigation. The respondents challenged the validity of the Cape Town warrants in the High Court, arguing that the omission rendered them invalid and that the magistrates had failed to apply their minds. The High Court and later the Supreme Court of Appeal set aside the warrants on the basis that failure to specify the offence breached the intelligibility requirement. The Minister sought leave to appeal to the Constitutional Court.

Leave to appeal was granted. The Constitutional Court overturned the reasoning that omission of the offence automatically invalidates a warrant, and clarified the proper test for validity based on intelligibility. The appeal succeeded to the extent that the strict offence-specification requirement was rejected.

This case authoritatively clarified South African law on the validity of search and seizure warrants under the Criminal Procedure Act. It resolved more than a century of uncertainty by confirming that intelligibility, not formalistic offence-specification, is the constitutional standard. The judgment balances effective law enforcement with constitutional protections of privacy and dignity.
