Ar wahân i’r mater hwnnw, ar 9 Rhagfyr, cyhoeddodd Neil O'Brien AS, yr Is-ysgrifennydd Gwladol Seneddol dros Ffyniant Bro, yr Undeb a'r Cyfansoddiad Ddatganiad Ysgrifenedig Gweinidogol i Senedd y DU ar ddefnyddio adran 12 o Ddeddf yr Undeb Ewropeaidd (Ymadael). Roedd y datganiad hwn yn nodi, o ganlyniad i'r cynnydd a wnaed i sefydlu Fframweithiau Cyffredin mewn cydweithrediad â'r llywodraethau datganoledig, fod Llywodraeth y DU yn bwriadu diddymu adran 12 (y "pŵer rhewi") drwy ddefnyddio'r pŵer galluogi a nodir yn adran 12(9) o'r Ddeddf. Rydym yn croesawu'r diddymiad hwn a'r ffaith nad yw'r “pŵer rhewi” erioed wedi'i arfer.
Separately, on 9 December the Minister for Levelling Up, The Union and Constitution, Neil O’Brien MP, issued a Written Ministerial Statement to the UK Parliament on the use of section 12 of the EU (Withdrawal) Act. This stated that, as a result of the progress that had been made to establish Common Frameworks in collaboration with the Devolved Governments, the UK Government intended to repeal section 12 (the “freezing power”) through the use of the enabling power set out in section 12(9) of the Act. We welcome this repeal and the fact that the freezing power has never been exercised.
