It is worth outlining briefly the logic behind the selection of the Articles of the Treaty of Nice which, through the Bill, are to be made part of domestic law and to explain the basis on which the decisions were made. Article 1 of the Treaty of Nice amends aspects of the Treaty on European Union. Measures adopted under that treaty in the foreign policy and justice and home affairs areas differ from directives, regulations and decisions adopted under the Community treaties in the mainstream social and economic sectors. The major difference is that they do not have direct legal effect. The obligations created are essentially intergovernmental.
