Opinion 2/15 of the Court of Justice of the European Union on EU-Singapore Free Trade Agreement is important since it determines the EU competence and conclusion procedure of similar new generation trade agreements. This paper aims to analyse the effects of the Opinion 2/15 on EU's competence to conclude international agreements, conclusion of similar agreements and Modernisation of the Customs Union between Turkey and the EU. It is concluded that Court's broad interpretation of the EU's exclusive competence strengthens EU's external power legally, through providing the opportunity to ratify international agreements alone; but it creates new ambiguities about the EU's competence on investments. Regarding to the Customs Union, inclusion of the subjects of the revision negotiations to the EU's exclusive competences, is evaluated as a positive development in terms of legal certainty.
