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 mabwysiadwyd gan yr UE): Mae'r wreiddiol version of the legislation as it stood when it was first adopted in the EU. No changes have been applied to the text.

Pwynt Penodol mewn Amser: This becomes available after navigating to view revised legislation as it stood at a certain point in time via Advanced Features > Show Timeline of Changes or via a point in time advanced search.

Llinell Amser Newidiadau

Mae’r llinell amser yma yn dangos y fersiynau gwahanol a gymerwyd o EUR-Lex yn ogystal ag unrhyw fersiynau dilynol a grëwyd ar ôl y diwrnod ymadael o ganlyniad i newidiadau a wnaed gan ddeddfwriaeth y Deyrnas Unedig.

Cymerir dyddiadau fersiynau’r UE o ddyddiadau’r dogfennau ar EUR-Lex ac efallai na fyddant yn cyfateb â’r adeg pan ddaeth y newidiadau i rym ar gyfer y ddogfen.

Ar gyfer unrhyw fersiynau a grëwyd ar ôl y diwrnod ymadael o ganlyniad i newidiadau a wnaed gan ddeddfwriaeth y Deyrnas Unedig, bydd y dyddiad yn cyd-fynd â’r dyddiad cynharaf y daeth y newid (e.e. ychwanegiad, diddymiad neu gyfnewidiad) a weithredwyd i rym. Am ragor o wybodaeth gweler ein canllaw i ddeddfwriaeth ddiwygiedig ar Ddeall Deddfwriaeth.
