The Competition Commission referred a complaint alleging collusive tendering under section 4(1)(b)(iii) of the Competition Act 89 of 1998 arising from a tender issued by Airports Company of South Africa (ACSA) for retail space at OR Tambo International Airport. Tourvest, an established airport curio retailer, and Siyazisiza Trust, a non-profit rural craft supplier, collaborated in relation to Opportunity 3 of the tender. The Trust lacked the capacity and mandatory requirements to bid independently and relied on Tourvest’s expertise, infrastructure and management under a disclosed memorandum of understanding (MoU). Both Tourvest and the Trust submitted bids with identical rental figures, expressly disclosed their relationship, and Tourvest submitted its own bid as a fallback in case the Trust was disqualified. The Trust’s bid was eliminated at the outset for failure to meet mandatory administrative requirements. Despite this, ACSA later disqualified all Tourvest bids alleging collusion. The Competition Tribunal found both parties guilty of collusive tendering and imposed an administrative penalty on Tourvest. Tourvest appealed to the Competition Appeal Court.
