The matter concerned proposed mergers involving major banks and insurance companies, including Standard Bank Investment Corporation, Liberty Life, Nedcor and Old Mutual. The Competition Commission asserted jurisdiction under the Competition Act 89 of 1998 to investigate and control the mergers as large mergers. The appellants contended that the mergers were excluded from the Competition Act’s application by section 3(1)(d), on the basis that the transactions were subject to regulation and approval under sector-specific legislation, notably the Banks Act and the Long-term Insurance Act, by designated regulatory authorities.
