Y Diweddaraf sydd Ar Gael (diwygiedig):Y fersiwn ddiweddaraf sydd ar gael o’r ddeddfwriaeth yn cynnwys newidiadau a wnaed gan ddeddfwriaeth ddilynol ac wedi eu gweithredu gan ein tîm golygyddol. Gellir gweld y newidiadau nad ydym wedi eu gweithredu i’r testun eto yn yr ardal ‘Newidiadau i Ddeddfwriaeth’.
Gwreiddiol (Fel y’i Deddfwyd neu y’i Gwnaed): Mae'r wreiddiol fersiwn y ddeddfwriaeth fel ag yr oedd pan gafodd ei deddfu neu eu gwneud. Ni wnaed unrhyw newidiadau i’r testun.
Mae Memoranda Esboniadol yn nodi datganiad byr o ddiben Offeryn Statudol ac yn rhoi gwybodaeth am ei amcan polisi a goblygiadau polisi. Maent yn ceisio gwneud yr Offeryn Statudol yn hygyrch i ddarllenwyr nad oes ganddynt gymhwyster cyfreithiol, ac maent yn cyd-fynd ag unrhyw Offeryn Statudol neu Offeryn Statudol Drafft a gyflwynwyd ger bron y Senedd o Fehefin 2004 ymlaen.
