Following an investigation into the flexible polyurethane foam market, the Competition Commission referred complaints to the Competition Tribunal alleging horizontal restrictive practices. The first complaint alleged that Loungefoam, Vitafoam and/or Gommagomma fixed selling prices of foam and jointly fixed purchase prices of chemicals (the 'chemical cartel'), contrary to section 4(1)(b)(i) of the Competition Act 89 of 1998. The second complaint alleged market division between Feltex, on the one hand, and Loungefoam and Vitafoam, on the other, contrary to section 4(1)(b)(ii). During preparation for the Tribunal proceedings, the Commission sought to amend its founding affidavit to implicate Feltex in the chemical cartel and to introduce allegations of collusion between companies in the Steinhoff group and the KAP group. The Commission further sought to rely on section 4(5)(b) to attach liability for any administrative penalty to Steinhoff International Holdings Ltd and Steinhoff Africa Holdings (Pty) Ltd, and to join Steinhoff Africa as a party. The Tribunal granted the amendments and joinder. Feltex and the Steinhoff companies appealed and, in the alternative, brought review proceedings challenging the Tribunal’s decisions.
