The EU Commission has proposed that treaties and very important constitutional decisions might be amended by a new decision-making method located somewhere between qualified majority voting and unanimity.
They propose that five-sixths of the Member States shall be able to approve a change. Member States that fail to approve such changes will then be excluded from membership. A superqualified majority may also be 90%, or another figure above the 71.26 % that defines a qualified majority at present.
The Constitution proposes that a super qualified majority shall be composed of 72% of the Member States comprising, 65% of the EU-population. The super qualified majority will be used when the Council or the European Council is taking a decision not proposed by the Commission or the Foreign Minister.
