Cafodd cais Llywodraeth Cymru am ganiatâd ei wrthod gan y Llys Adrannol, ar y sail ei fod yn rhy gynnar. Ni ffurfiodd y Llys farn ar sylwedd y cais. Cyflwynwyd apêl yn dilyn hyn.
The Welsh Government’s application for permission was refused by the Divisional Court, on the ground that it was premature. The Court did not form a view on the substance of the claim. An appeal was subsequently submitted.
