A Bill is a draft law. Once a Bill has been considered and passed by the Senedd and given Royal Assent by the Monarch, it becomes an ‘Act of Senedd Cymru’. The Senedd is able to pass Acts on any matters that are not reserved to the UK Parliament by the Government of Wales Act 2006 (as amended by the Wales Act 2017).

A Members’ Bill is a Bill introduced by an individual Member of the Senedd. Members’ Bills are distinct from Bills (introduced by the Welsh Government), Committee Bills (introduced by a committee) and Commission Bills (introduced by the Senedd Commission).

Legislative Consent

When the UK Parliament wishes to legislate on a subject matter which has already been devolved to the Senedd, convention requires it to receive the consent of the Senedd before it may pass the legislation in question. Such consent is given by the Senedd through Legislative Consent Motions (LCMs).
