Abstract

The main subject of the present research is the enforcement of the European Union law in the domestic legal order. This topic was chosen considering the Treaty of Lisbon amending the Treaty on the European Union and the Treaty establishing the European Community and especially its declaration No. 17 on primacy of EU law. This article will explain the meaning of primacy of the European Union law and the resulting problems in some EU Member States, as well as possible solutions to tackle the problems. The primacy of the European Union law over the national law was recognised as one of the constitutive principles of the European Union. The article includes relevant provisions of the Lisbon Treaty that deal with the rules concerning the legal requirements of the primacy of the European Union law in the EU primary law. The European Court of Justice has developed the meaning of the principle of primacy, which means that the European Union law should take precedence over national law (even over constitutional provisions) and should there be any conflicts between EU law and national law, every national court is obliged to apply the law of the European Union. The main issue of this article is analysing the principle of primacy of the European Union law over the Lithuanian law
