Rhoddwyd y gorau i waith y Comisiwn dros dro yn sgil cyhoeddi adroddiad Mathias, sef adolygiad annibynnol o’r materion ansawdd ac amserlennu a oedd yn gysylltiedig â rhaglen y Comisiwn o adolygiadau etholiadol. O ganlyniad i adolygiad Mathias, a’r camau a ddeilliodd o hwnnw, nid oedd yn bosibl cwblhau’r adolygiad o drefniadau etholiadol Ynys Môn mewn pryd.
The Commission’s work was suspended following publication of the Mathias report - an independent review of the timetabling and quality issues associated with the electoral review programme by the Commission. As a result of the Mathias review and its resultant actions the deadline for completing the review of Anglesey’s electoral arrangements could not be adhered to.
