The Commissioner for Customs and Excise claimed payment of customs duties from Standard General Insurance Company Limited, which had stood surety for a licensed clearing agent, Gem Shipping, under deferment arrangements in terms of the Customs and Excise Act 91 of 1964. Gem Shipping failed to pay duties that became due on 14 February 1993 and was later liquidated. The Commissioner demanded payment from Standard General under two suretyships (R10 000 and R50 000 respectively). Summons was issued in June 1995. Standard General raised a special plea relying on s 99(5) of the Customs Act, which provides that liability ceases after two years from when it was incurred. The Commissioner argued that the running of prescription was delayed by lodging a claim against Gem Shipping’s insolvent estate in terms of the Prescription Act.
