Passerelle clause

A passerelle clause is a clause in treaties of the European Union that allows the alteration of a legislative procedure without a formal amendment of the treaties. The use of a passerelle clause required unanimity of all member states although member states with opt-outs and those not participating in an area under enhanced cooperation may not have a vote. Unlike formal treaty revision their use does not require national ratification. Passerelle is French for a 'small bridge'.
