Status of European collective self-defense in the international law and order

Abstract

By the entry into force of the Lisbon Treaty, the obligation of the collective self-defense of the meber states has been laid dawn in the basic document of the European Union. Although the need for a European collective self-defense already appeared some time ago, phrasing it at EU level was hindered by many circumstances. The author of this article intends to introduce the system of the collective self-defense in the international law, as well as to present anomalies related to the possible use of the EU collective self-defense clause.
