In Wales, an Act of the National Assembly for Wales (Welsh: Deddf Cynulliad Cenedlaethol Cymru) (informally, an Act of the Assembly) is primary legislation that can be made by the National Assembly for Wales under part 4 of the Government of Wales Act 2006. The power to make Acts of the Assembly was conferred on the assembly following the 2011 elections as a commencement order had been passed in the assembly by simple majority prior to dissolution. The activation of part 4 legislative powers was as a result of a "yes" vote in the 2011 referendum held in Wales. When the power to make Acts of the Assembly commenced, the assembly lost the ability to make Measures under part 3 of the 2006 Act. Existing Measures will remain as law unless repealed.
