Abstract: | There are several reasons why to write about European Constitution, more precisely about the Treaty of Lisbon (founding treaties) of the European Union (EU), the case – law of the Court of Justice of the EU (CJEU), and national constitutions of the Member states of the EU. One of the most important is that the analysis of the EU’s constitutional development, it’s current constitutional concept, as well as the future of its constitutionalization process, should contribute to our knowledge of the Union itself. This is necessary today when the integration of the Republic of North Macedonia into the EU has already reached the point where a decision was made by the European Council to start accession negotiations, and the commencement of the negotiation process is expected. Apprehension of the constitutional framework according to which the Union functions can make things easier for many participants in these negotiations : politicians, member of various institutions, legal and other experts expected to take part in the process etc. Legal, economics, political and other studies of European integration at our faculties of law should be acquainted with the basic characteristics of the EU, as a community based on common values and law, as a political and legal community and a single space of freedom, security, and justice. |
