The relationship between the constitutional norms and the European Union law is interpreted differently, as there are several doctrinal conceptions and different case law solutions. A trend of thought affirms the supremacy of the Constitution, including over the European Union law, even though it accepts the priority of application of the latter, in its binding rules, over all the other rules of domestic law, and other trend affirms the priority of the unconditional application of all the provisions of the European Union law over all the norms of the domestic law, including over the constitutional norms. There are European constitutional jurisdictions which have established that they have the competence to conduct the control over the constitutionality of the European Union law, integrated into the domestic legal order, by virtue of the principle of supremacy of the Basic Law. In this study we analyze the interferences between the principle of priority of the European Union law and the principle of supremacy of the Constitution with reference to the doctrine and the relevant case law in the matter.
Key words: principle of priority of the European Union law; principle of supremacy of the Constitution; obligativity of the legal norms of the European Union; control of the constitutionality of the legal acts of the European Union integrated into the domestic law; compliance of the domestic law with the European Union law.
