Any Member wishing to propose a Bill must apply to be included in a ballot which is held by the Presiding Officer.
A Member who is successful in the ballot may then table a motion asking the Senedd to agree that they can introduce a Bill to give effect to the proposal included in the explanatory statement tabled with the motion. If that motion is agreed, the Member has 13 months in which he or she may formally introduce a Bill.
Once introduced, a Member Bill is subject to the same scrutiny process as other Bills.
