Pine Glow Investments (Pty) Ltd (Pine Glow) held a site licence for a Caltex filling station in Acornhoek, Mpumalanga. Erf 6 Highveld Technopark Investments (Pty) Ltd (Erf 6) and NAD Property Income Fund (Pty) Ltd (NAD) applied to the Controller of Petroleum Products (the Controller) for retail and site licences for a competing filling station. Pine Glow objected, and the Controller initially refused the applications on 9 November 2018. Erf 6 and NAD appealed to the Minister of Energy in terms of s 12A of the Petroleum Products Act 120 of 1977. On 12 December 2019, the Minister upheld the appeal, set aside the Controller's refusal, and referred the applications back to the Controller for re-evaluation with additional information submitted during the appeal. Following investigations, visits, and obtaining further information, the Controller approved the applications and issued the licences on 12 November 2020. Pine Glow brought a review application to set aside both the Minister's decision and the Controller's decision. Before the court of first instance, Pine Glow abandoned its challenge to the Minister's decision. Both the Mpumalanga High Court and the full court dismissed Pine Glow's review, with the full court finding that Pine Glow had failed to exhaust its internal remedy of appealing to the Minister against the Controller's decision.
