The submission by a Member State of instruments of Community law covered by the EC and EAEC Treaties to a judicial forum other than the Court, such as an arbitral tribunal established pursuant to Annex VII to the United Nations Convention on the Law of the Sea, for purposes of their interpretation and application in the context of proceedings seeking a declaration that another Member State had breached the provisions of those instruments is at variance with the obligation imposed on Member States by Articles 292 EC and 193 EA to respect the exclusive nature of the Court’s jurisdiction to resolve disputes concerning the interpretation and application of provisions of Community law, in particular by having recourse to the procedures set out respectively in Articles 227 EC and 142 EA for the purpose of obtaining a declaration that another Member State has breached those provisions. Furthermore, in those circumstances, the institution and pursuit of proceedings before the arbitral tribunal involve a manifest risk that the jurisdictional order laid down in the Treaties and, consequently, the autonomy of the Community legal system may be adversely affected.
