Airports Company South Africa SOC Ltd (ACSA), an organ of state, issued a Request for Bids (RFB) in September 2017 inviting bids for ten-year car rental concessions at nine airports. The RFB contained pre-qualification and evaluation criteria, including mandatory transformation and B-BBEE requirements, and a preferential scoring system. Imperial Group Ltd, a large car rental company, submitted a bid under reservation and challenged the lawfulness of the RFB, contending that several provisions contravened s 217 of the Constitution and the statutory procurement framework (including the Preferential Procurement Policy Framework Act and B-BBEE legislation). Imperial argued that the pre-qualification criteria would automatically disqualify it at the first stage. The High Court reviewed and set aside the RFB as unlawful and invalid. ACSA appealed to the Supreme Court of Appeal, arguing that the review was premature and that s 217 did not apply because the RFB involved granting concessions and generating revenue rather than state expenditure.
