Antitrust, which is also known in some jurisdictions as Competition Regulations, is generally perceived as a technical subject that is not easily understood. In developing countries, there is a paucity of antitrust legislation which accounts for the in effective application of deregulation policies which in effect inhibits designs to protect the consumer, promote free trade and commerce, and prevent unwholesome and unethical trade practices. In the United States of America and the European Union, antitrust legislation is fortified and the utilitarian values seemingly obvious in the telecomm sector. Unlike the USA and the EU models of regulation which are anchored on the antitrust model, the Nigerian regulatory framework is not based on competition rules. Nigeria has not given the antitrust law model of regulation a priority despite its pursuit of economic liberalization, through privatization of government-owned commercial enterprises and deregulation policies. This work sets out to X-ray the Nigerian antitrust models vis-à-vis the United States of America. The goal is to sort out those desirable features that can be domesticated in the Nigerian economy for effective and efficient telecommunications regulations for enhanced consumer protection.
