The Competition Commission initiated a complaint in January 2009 alleging that four firms supplying mining roof bolts—RSC Ekusasa, Duraset, DSI and Videx—had engaged in cartel conduct between 2004 and 2008, involving customer allocation, market sharing and collusive tendering. RSC received corporate leniency and Duraset settled with the Commission. The Commission referred the complaint to the Competition Tribunal in 2010. Evidence was led mainly through former executives of RSC and Duraset. The Tribunal rejected the existence of an overarching cartel agreement, found several alleged incidents time-barred under section 67(1) of the Competition Act 89 of 1998, but held that a 2005 Amplats reverse auction involved a continuing prohibited practice not time-barred. Videx was found liable for that incident alone and fined. Videx appealed against the finding and penalty, while the Commission cross-appealed, contending that an overarching agreement existed and that additional incidents should have been adjudicated.
