(24)Since only institutions of the Union may establish the resolution policy of the Union and since a margin of discretion remains in the adoption of each specific resolution scheme, it is necessary to provide for the adequate involvement of the Council and the Commission, as institutions which may exercise implementing powers, in accordance with Article 291 TFEU. The assessment of the discretionary aspects of the resolution decisions taken by the Board should be exercised by the Commission. Given the considerable impact of the resolution decisions on the financial stability of Member States and on the Union as such, as well as on the fiscal sovereignty of Member States, it is important that implementing power to take certain decisions relating to resolution be conferred on the Council. It should therefore be for the Council, on a proposal from the Commission, to exercise effective control on the assessment by the Board of the existence of a public interest and to assess any material change to the amount of the Fund to be used in a specific resolution action. Moreover, the Commission should be empowered to adopt delegated acts to specify further criteria or conditions to be taken into account by the Board in the exercise of its different powers. Such a conferral of resolution tasks should not in any way hamper the functioning of the internal market for financial services. EBA should therefore maintain its role and retain its existing powers and tasks: it should develop and contribute to the consistent application of the Union legislation applicable to all Member States and enhance convergence of resolution practices across the Union as a whole.
