Formalito (Pty) Ltd, a licensed arms dealer, imported firearms and ammunition into South Africa. SARS received information that Formalito had under-declared the value of imported goods by using incorrect tariff codes on bills of entry between 1998 and 2000, resulting in an underpayment of customs duty, ad valorem duty and VAT amounting to R696 652.95. SARS demanded payment of the underpaid duties and imposed an additional amount in lieu of forfeiture under s 88(2)(a) of the Customs and Excise Act, ultimately fixing this penalty at 50% of the value of the goods (R1 896 456). Formalito successfully reviewed these decisions in the High Court, which set aside both the duty claim and the forfeiture. SARS appealed to the Supreme Court of Appeal.
