Nod y Bil yw creu Senedd fodern, sy’n gallu cynrychioli pobl Cymru’n well. Bydd ganddi fwy o allu i graffu, llunio cyfreithiau, a dwyn y llywodraeth i gyfrif. Mae hefyd yn rhoi argymhellion y Pwyllgor Diben Arbennig ar Ddiwygio’r Senedd ar waith. Cefnogwyd yr argymhellion hyn gan y mwyafrif o Aelodau’r Senedd ym mis Mehefin 2022.
The Bill aims to create a modern Senedd, better able to represent people in Wales, with increased capacity to scrutinise, make laws, and hold the government to account. It also realises the recommendations made by the Special Purpose Committee on Senedd Reform, which were endorsed by a majority of Senedd Members in June 2022.
