Glencore Operations SA (Pty) Ltd, a coal mining company and holder of mining rights under the Mineral and Petroleum Resources Development Act 28 of 2002, used diesel fuel in various mining-related activities at its Mpumalanga mines between August 2011 and 13 December 2013. Diesel fuel is subject to the fuel levy and Road Accident Fund levy under the Customs and Excise Act 91 of 1964. The Act provides a rebate for diesel used in 'own primary production activities in mining' under s 75(1A) read with Item 670.04 and Note 6(f)(iii) of Part 3 of Schedule 6. Glencore claimed refunds of diesel levies for this period. The Commissioner for SARS disallowed part of the claims, contending that the diesel was used in secondary mining activities, not qualifying primary production. Glencore appealed to the Gauteng Division of the High Court, which upheld its appeal and set aside the Commissioner’s determination. SARS then appealed to the Supreme Court of Appeal.
