48As regards, second, the fact that the contested act makes no reference to the legal basis on which it is adopted, it must be observed, at the outset, that an indication of the legal basis is essential in the light of the principle of the allocation of powers enshrined in Article 5(2) TEU, according to which the European Union must act within the limits of the competences conferred on it by the Member States in the Treaties to attain the objectives set out in the Treaties with respect to both the internal action and international action of the European Union (see, to that effect, Opinion 2/94 (Accession of the Community to the ECHR) of 28 March 1996, EU:C:1996:140, paragraph 24, and judgment of 1 October 2009, Commission v Council, C‑370/07, EU:C:2009:590, paragraph 46).
