The applicant, a registered company importing luxury motor vehicles, placed imported vehicles in its bonded warehouse pending sale. Customs duty and VAT were calculated at the port of entry but payment was deferred until removal from the warehouse. The dispute arose from the introduction of SI 80A of 2007 on 5 April 2007, which required importers to pay duty in foreign currency for luxury items. The applicant imported motor vehicles in three categories: (a) before 5 April 2007, (b) before 6 September 2007, and (c) imported before 6 September 2007 but warehoused on or after that date. The initial duty calculations used an exchange rate of Z$250 to US$1, but the rate changed to Z$30,000 to US$1 on 6 September 2007. When the applicant sought to remove vehicles from the warehouse, the respondent required payment at the exchange rate prevailing at importation, while the applicant argued the rate at removal should apply. The case was complicated by the introduction of multi-currency use in February 2009 and demonetization of the Zimbabwe dollar.
