The Relationship Between Member State Liability in Damages for Breach of the European Union Law and State Responsibility for Breach of International Law

Abstract

This article analyses that state responsibility in international law is contractual liability, as a state infringes its obligations to another state (states), stemming out of international law. Member State liability in damages to a private party for breach of European Union law is, contrarily, non-contractual liability to a private party. Having analysed the elements of internationally wrongful act, it is stated that the elements of internationally wrongful act can be used to determine the elements of breach of the European Union law. Thus if an international court declares that a state committed an internationally wrongful act, it would be possible to maintain that the elements of breach of the European Union law are met as well. The author of this article notes that it is very important to identify a particular state institution, which has infringed the European Union or international law, as not attributing to the state the acts of the state institution under the European Union or international law, there should be no possibility to apply state liability in damages to a private party for breach of the European Union law or state responsibility in international law – the state can be liable only for acts of its institutions. This article also analyses the cases where application of both Member State’s liability in damages to a private party for breach of the European Union law and state responsibility in international could be possible. In such case a private party can suffer damages if a Member State breaches an international agreement, concluded by the European Union, imposing particular obligations on that Member State. Therefore, it is ascertained that a private party should not have to prove the second condition of liability – sufficient seriousness of the breach1 – if an international court foremost states that a Member State commited an internationally wrongful act – breached its obligation arising out of an international agreement entered into by the European Union. Such an infringement would be considered to be as sufficiently serious per se.
