(85)The Commission has stated in its Communication of 28 November 2012 on a Blueprint for a deep and genuine economic and monetary union that Article 127(6) TFEU could be amended to make the ordinary legislative procedure applicable and to eliminate some of the legal constraints it currently places on the design of the SSM (e.g. enshrine a direct and irrevocable opt-in by Member States whose currency is not the euro to the SSM, beyond the model of ‘close cooperation’, grant Member States whose currency is not the euro participating in the SSM fully equal rights in the ECB’s decision-making, and go even further in the internal separation of decision-making on monetary policy and on supervision). It has also stated that a specific point to be addressed would be to strengthen democratic accountability over the ECB insofar as it acts as a banking supervisor. It is recalled that TEU provides that proposals for treaty change may be submitted by the Government of any Member State, the European Parliament, or the Commission, and may relate to any aspect of the Treaties.
