Consumer law is an innovative branch of law that started to develop in the second half of the 20th century. The establishment and evolution of consumer law represents the outcome of political willingness to develop and promote the rights and interests of consumers as fundamentally important players in the market. Consumers need a particular regime of protection due to their status as weaker parties in relations with traders. Consumer policy represents the outcome, but is also an instrument, of the foundations of the market and society that have been redefined by material changes. As a consequence, many countries worldwide have adopted diverse forms of national regulatory frameworks for the protection of consumers. However, the process of defining and drafting consumer law and policy has never been exclusively limited to national frontiers. International and regional subjects have traditionally played an important role, which has given more prominence to consumer protection. Today, the regionalisation and internationalisation of consumer law and policy are increasing. Consumer law is increasingly becoming a supranational phenomenon. There are two aspects to this phenomenon: the regional perspective and the international perspective.
