A school that is subject to intervention by a local authority or Welsh Ministers cannot request to leave a federation unless those persons have firstly given their consent.
Os yw'r ysgol yn ddarostyngedig i ymyriad gan Weinidogion Cymru neu gan awdurdod lleol, ni chaiff wneud cais am gael gadael ffederasiwn oni fydd y personau hynny wedi cydsynio ymlaen llaw.
