This research comprises of two parts. The first part analyses the most important issues of the principle of Member State's liability in damages for the breach of European Union law: legal basis of the principle, requirements for liability and, lastly, recent developments in the case law of the Court of Justice of the European Union. The principle of Member State's liability in damages and the requirements of liability are being further developed by the Court in its modern jurisprudence.

The author also examines that the state liability is being recognised both in EU and international law.
