The late Mr Nicolaas Petrus Gouws owned Portion 9 of the farm Driefontein 338, Middelburg, and held an unused old order mineral right for coal prior to the commencement of the Mineral and Petroleum Resources Development Act 28 of 2002 (MPRDA). Shortly before expiry of the transitional period, he applied for conversion of his unused old order right to a new order prospecting right. A competing prospecting application was lodged by Magnificent Mile Trading 30 (Pty) Ltd. Mr Gouws died after lodging his application but before it was decided. Due to serious administrative errors, the Department of Mineral Resources granted a prospecting right to Mr Gouws in respect of the wrong property and later attempted to amend and rectify that grant. Further prospecting rights were registered in favour of his widow and executor. Magnificent Mile’s application for a mining right was refused because of the purported prospecting right held by the Gouws estate. Magnificent Mile successfully reviewed and set aside several of these decisions in the High Court, which also substituted a refusal of Mr Gouws’ prospecting application and granted Magnificent Mile a mining right. The executor of the Gouws estate appealed to the Supreme Court of Appeal.
