The Competition Commission initiated a complaint against various steel producers and merchants alleging cartel conduct in contravention of s 4(1)(b) of the Competition Act 89 of 1998. Scaw South Africa applied for and was granted conditional leniency under the Commission’s Corporate Leniency Policy (CLP). Following the Commission’s referral of a complaint to the Competition Tribunal, ArcelorMittal South Africa Ltd (AMSA) and Cape Gate (Pty) Ltd sought access to documents in the Commission’s possession, including Scaw’s marker and leniency applications and related documents, relying on Competition Commission Rules, High Court Rule 35(12), and PAJA. The Commission refused disclosure, claiming the documents were restricted information under CC Rule 14(1)(e) read with s 37(1)(b) of PAIA. The Tribunal dismissed the applications, and AMSA and Cape Gate appealed (and AMSA also sought review) to the Competition Appeal Court.
