The objective of the Treaty of Rome has not only been to create a Common Market within which there would be a free circulation of goods, services, persons and capital. Article 2 of the Treaty sets the target of ‘establishing a Common Market and progressively approximating the economic policies of member states …’.[ 1 ] Nevertheless, in the Treaty itself there is a clear contrast between those Articles devoted to the elimination of trade barriers and those devoted to the development of common economic policies. Rather precise timetables are set for the elimination of tariffs and other obstacles to trade, while the Articles on the subject of common policies do not seem to express anything more than a fairly vague agreement about general objectives. Justifiably enough, the Treaty of Rome has been described as a Traité-cadre.[ 2 ]
