Stabilization and association treaties in the law of the European Union
The European Communities did not cease to exist after the foundation of the European Union by the Treaty of Mastricht in 1992. In fact, they act as pillars on which the European Union stands, together with the Police and Judicial Cooperation in Criminal Matters and Common Foreign and Security Policy. The European Union does not have the status of a legal entity or a capacity to enter into treaties with third countries or international organization. In both foreign and domestic proceedings it relies upon the institutions and instruments of the European Communities. The European Communities are autonomous in relation to the European Union and act in accordance with the rules contained in the foundation Treaties, which, however, make a constituent part of the Treaty on European Union. The foundation Treaties of the European Communities provide for a possibility for the Communities to enter into international treaties with third countries or international organizations. Stabilization and Association Treaties belong to the category of Association Treaties defined in Article 310 of the Treaty on European Union. Considering that these treaties regulate certain fields which belong to competence of the member states, the member states are usually parties to these treaties along with the European Communities. International treaties entered into between the European Communities and third countries are binding upon the Community institutions and upon member states. International treaties entered in this way are considered a part of Community law. Member states are bound to recognize such effects to these treaties as are provided in the Community law itself.
