Cyflwynwyd y Bil er mwyn gwella’r prosesau democrataidd mewn perthynas â llywodraeth leol, a gweithrediad y Comisiwn Ffiniau Llywodraeth Leol i Gymru yn benodol. Gwneir hynny mewn ymateb i ganfyddiadau Adolygiad Mathias o broses adolygiadau etholiadol y Comisiwn, a gyhoeddwyd ym mis Mehefin 2011.
The Bill has been introduced to improve democratic processes concerning local government, in particular the operation of the Local Government Boundary Commission for Wales. This is in response to the findings of the Mathias Review of the Commission’s electoral review process, which was published in June 2011.
