The respondents, two individuals and associated companies, were under investigation and later indicted on thousands of counts of fraud and statutory contraventions. In March 2005, the South African Police Service executed search warrants issued under s 21 of the Criminal Procedure Act 51 of 1977 at several premises and seized approximately 400 000 documents. The documents were sealed in boxes pursuant to an agreement between the police and the respondents’ attorney, allowing later identification of privileged material. No privilege was claimed during the searches. Subsequently, an agreed process with an independent advocate identified and returned about 18 000 pages of privileged documents, none of which were read by police. The respondents nonetheless approached the Pretoria High Court, which declared the execution of the warrants unlawful and ordered the return of all seized documents. The Minister of Safety and Security and others appealed to the Supreme Court of Appeal.
