Goodyear South Africa (Pty) Ltd is one of several tyre manufacturers accused by the Competition Commission of participating in a cartel between 1999 and 2007 to fix tyre prices, in contravention of section 4(1)(b)(i) of the Competition Act 89 of 1998. The matter, initiated following a complaint in 2006, has been subject to prolonged litigation and interlocutory disputes. At a pre-hearing conference in December 2021 before the Competition Tribunal, Goodyear sought to introduce an economist’s expert report to support its defence that its price increases were unilateral and driven by raw material costs. The presiding Tribunal member, sitting alone, issued a written directive refusing to admit the expert report as an expert witness statement. Goodyear appealed this directive to the Competition Appeal Court.
