The appellants, acting through a trust, sought permission from SANRAL to construct and operate a filling station and rest facility alongside the N12 national road. Negotiations commenced in 2016 under a SANRAL policy that levied 0.5% on petroleum sales and 1% on other sales. After all requirements were met and a draft agreement was issued in January 2021, SANRAL introduced substantially increased levies (2.5% and 6%) based on a newly adopted 2021 policy aligned with its Horizon 2030 strategy. The policy was applied retrospectively to the appellants’ pending agreement. The appellants contended that the policy was adopted without proper publication, gazetting, or public participation as required by the SANRAL Act, and that the increased levies rendered the project commercially unviable. They sought judicial review of SANRAL’s decision. The High Court dismissed the review, holding that SANRAL acted as a contracting party. The appellants appealed to the Supreme Court of Appeal.
