Competition Commission of South Africa v Interaction Market Services Holdings (Pty) Ltd

The Competition Commission referred a complaint to the Competition Tribunal alleging that Interaction Market Services Holdings (Pty) Ltd (IMSA) and other fresh produce market agents contravened section 4(1)(b)(i) of the Competition Act 89 of 1998 by agreeing, alternatively engaging in a concerted practice, to fix base commission rates charged to farmers for selling fresh fruit and vegetables across South Africa. IMSA is a voluntary association whose members allegedly enforced uniform commission caps, including a maximum 9.5% commission. After the Tribunal upheld a first exception and ordered supplementation of the referral, the Commission filed a supplementary affidavit. IMSA raised a second exception, contending that the Commission still failed to plead with sufficient precision, particularly regarding the existence of an agreement or concerted practice, market definition, geographic markets, value chain, and anti-competitive effects. The Tribunal upheld the second exception and ordered further particulars. The Commission appealed to the Competition Appeal Court.

The appeal was upheld; the Competition Tribunal’s decision and order upholding the second exception were set aside; the respondent was directed to file its answering affidavit within 10 days; no order as to costs was made.

The case clarifies pleading standards in cartel prosecutions under section 4(1)(b) of the Competition Act and reinforces that such offences are per se, requiring no pleading or proof of anti-competitive effects. It affirms the flexible, inquisitorial nature of Competition Tribunal proceedings and limits the scope of exceptions that would otherwise impose High Court–style pleading requirements on the Commission. The judgment protects the Commission’s ability to prosecute cartel conduct effectively without premature evidentiary burdens.
