Walter Eleazar Cyril and Letisha Cyril were charged in a pending criminal trial with multiple counts of fraud and contraventions of the Customs and Excise Act 91 of 1964, arising from the alleged unlawful diversion of cigarettes without payment of duty or VAT. Evidence against them was obtained during a search of a bonded warehouse conducted by SARS under provisions of the Customs and Excise Act later declared unconstitutional in Gaertner v Minister of Finance. Although the Constitutional Court suspended the declaration of invalidity and ordered it not to operate retrospectively, the Cyrils challenged the admissibility of the evidence. After a trial-within-a-trial, the magistrate ruled the evidence admissible. While the criminal trial was still pending, the Cyrils launched a High Court review application to set aside that ruling. SARS, as complainant in the criminal case, applied for and was granted leave to intervene in the review application. The Cyrils appealed to the Supreme Court of Appeal against the High Court’s order granting SARS leave to intervene.
