ON 16 May 2017, the Court of Justice of the European Union (CJEU) delivered its Opinion 2/15 concerning the competence of the EU to conclude the Free Trade Agreement with Singapore (EUSFTA) (ECLI:EU:C:2017:376). The Opinion was requested by the Commission which argued, with the support of the European Parliament (EP), that the EU had exclusive competence to conclude the EUSFTA. The Council and 25 of the Member States countered that the EUSFTA should be concluded as a mixed agreement – that is, by the EU and each of its members – because some of its provisions fell under the shared competence of the organisation or the competence of the Member States alone.
