Any person may lodge a complaint against anticompetitive conduct with the Commission, at no charge. Chapter 2 of the Competition Act sets out what anticompetitive conduct is. In particular, the Act prohibits restrictive horizontal practices, restrictive vertical practices, abuse of dominance and price discrimination engaged in by a dominant firm. Restrictive horizontal practices refer to anticompetitive conduct carried out by competing firms, while restrictive vertical practices are those conducted by firms in a customer/supplier relationship with each other. Abuse of dominance, including price discrimination, refers to unilateral conduct engaged in by a dominant firm in a defined market. Section 6 and 7 of the Competition Act define the requirements for such dominance.
