The second appellant arrived at Johannesburg International Airport from overseas carrying 77 kg of jewellery belonging to the third appellant. He intended to travel later the same day to Namibia to offer the jewellery for sale. After receiving permission from a passport control officer to leave the transit area to meet his father, he passed through the green 'nothing to declare' customs channel without declaring the jewellery. Shortly thereafter, the police detained him and seized the jewellery under the Customs and Excise Act 91 of 1964. The following day, additional jewellery was seized from the business premises of the first appellant. The appellants sought the return of the seized goods, contending that the jewellery was not liable to forfeiture.
