European Union – Legal basis of regulation. The Court of Justice of the European Union granted the application by the European Parliament for: (i) annulment of Council Decision 2011/640/CFSP (the contested decision); and (ii) the maintenance of the effects of that decision. The Court decided that by failing to inform the European Parliament at all stages of the negotiations and of the conclusion of the EU-Mauritius Agreement, the Council had infringed art 218(10) on the Treaty of the Functioning of the European Union.
