Roedd Llywodraeth Cymru’n dibynnu ar Adran yr Amgylchedd, Bwyd a Materion Gwledig (Defra) i gyflwyno rhai diwygiadau canlyniadol i ddeddfwriaeth y Deyrnas Unedig wrth gyflwyno eu Rheoliadau diwygiedig.  Dyna’r ffordd arferol o ymdrin â materion fel hyn a hyd at ddoe, roedden ni’n disgwyl i’r diwygiadau cysylltiedig hynny gael eu gwneud.  Fodd bynnag, cefais wybod bod Defra wedi gosod eu Rheoliadau a’u tynnu’n ôl ar unwaith.  Nid wyf wedi cael gwybod y rheswm dros hyn ac rwyf wedi ysgrifennu at y Gwir Anrhydeddus Owen Patterson AS, yr Ysgrifennydd Gwladol dros yr Amgylchedd, Bwyd a Materion Gwledig, yn mynegi fy mhryderon ynghylch yr hyn y maen nhw wedi’i wneud.
The Welsh Government were relying on the Department for Environment, Food  and Rural Affairs (Defra) to bring forward some consequential amendments to UK legislation via the introduction of their updated Regulations.   This is a normal business approach and, until yesterday, we fully expected those linked amendments to be made.   However, I was informed that Defra had laid and immediately revoked their Regulations yesterday – I have not been informed of the reason behind their decision and have written to the Rt Hon Owen Patterson MP, Secretary of State for Environment, Food and Rural Affairs, to express my concern regarding their actions.
