- Gwreiddiol (Fel y’i mabwysiadwyd gan yr UE)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Mae unrhyw newidiadau sydd wedi cael eu gwneud yn barod gan y tîm yn ymddangos yn y cynnwys a chyfeirir atynt gydag anodiadau.Ar ôl y diwrnod ymadael bydd tair fersiwn o’r ddeddfwriaeth yma i’w gwirio at ddibenion gwahanol. Y fersiwn legislation.gov.uk yw’r fersiwn sy’n weithredol yn y Deyrnas Unedig. Y Fersiwn UE sydd ar EUR-lex ar hyn o bryd yw’r fersiwn sy’n weithredol yn yr UE h.y. efallai y bydd arnoch angen y fersiwn hon os byddwch yn gweithredu busnes yn yr UE. EUR-Lex Y fersiwn yn yr archif ar y we yw’r fersiwn swyddogol o’r ddeddfwriaeth fel yr oedd ar y diwrnod ymadael cyn cael ei chyhoeddi ar legislation.gov.uk ac unrhyw newidiadau ac effeithiau a weithredwyd yn y Deyrnas Unedig wedyn. Mae’r archif ar y we hefyd yn cynnwys cyfraith achos a ffurfiau mewn ieithoedd eraill o EUR-Lex. The EU Exit Web Archive legislation_originated_from_EU_p3
This is the revised version from EUR-Lex dated 01/05/2019. There are no timeline of changes available for treaties, instead, previous dated versions from EUR-Lex (as pdf) can be accessed via the More Resources menu.

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.
Rhychwant ddaearyddol: Indicates the geographical area that this provision applies to. For further information see ‘Frequently Asked Questions’.

Gallwch wneud defnydd o ddogfennau atodol hanfodol a gwybodaeth ar gyfer yr eitem ddeddfwriaeth o’r tab hwn. Yn ddibynnol ar yr eitem ddeddfwriaeth sydd i’w gweld, gallai hyn gynnwys:
This timeline shows the different points in time where a change occurred. The dates will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force. The first date in the timeline will usually be the earliest date when the provision came into force. In some cases the first date is 01/02/1991 (or for Northern Ireland legislation 01/01/2006). This date is our basedate. No versions before this date are available. For further information see the Editorial Practice Guide and Glossary under Help.
