Qualified majority rules ... As from 1 November 2014

Acts shall be adopted if there are at least 255 votes in favour representing a majority of the members where, under the Treaties, they must be adopted on a proposal from the Commission. In other cases decisions shall be adopted if there are at least 255 votes in favour representing at least two thirds of the
members.
A member of the European Council or the Council may request that, where an act is adopted by the European Council or the Council by a qualified majority, a check is made to ensure that the Member States comprising the qualified majority represent at least 62 % of the total population of the Union. If that proves not to be the case, the act shall not be adopted.
