Comisiynwyd Comisiwn y Gyfraith Cymru a Lloegr gan Lywodraeth Cymru i gwblhau adolygiad manwl o’r maes sylweddol a chymhleth hwn o’r gyfraith, gyda’r nod o symleiddio a chydgrynhoi’r ddeddfwriaeth. Er mwyn llywio’r adolygiad, fe aeth Comisiwn y Gyfraith ati i gynnal dau ymarferiad ymgynghori cyhoeddus. Gofynnwyd am safbwyntiau ar ei bapur cwmpasu (Mehefin 2016), a oedd yn cyflwyno ei safbwyntiau amodol, ac ar ei bapur ymgynghori sylweddol (Tachwedd 2017), a oedd yn cynnwys ei gynigion manwl.
The Law Commission for England and Wales was commissioned by the Welsh Government to undertake a detailed review of this substantial and complex area of law, with the aim of simplifying and consolidating the legislation. In order to inform their review, the Law Commission undertook two public consultation exercises. Views were sought on their scoping paper (June 2016), which set out their provisional views, and on their substantial consultation paper (November 2017) setting out their detailed proposals.
