Mae’r Llys Apêl, drwy Orchymyn dyddiedig 23 Mehefin, wedi rhoi caniatâd i apelio yn erbyn penderfyniad y Llys Adrannol, gan nodi bod rhesymau cryf dros wrando ar yr apêl hon yn y Llys Apêl. Nodwyd hefyd fod yr achos yn codi materion pwysig o ran egwyddor ynglŷn â’r berthynas gyfansoddiadol rhwng y Senedd a Senedd y DU.
The Court of Appeal, by Order dated 23 June, has granted permission to appeal the Divisional Court’s decision, noting there are compelling reasons for this appeal to be heard by the Court of Appeal and that the case raises important issues of principle going to the constitutional relationship between the Senedd and the Parliament of the UK.
