Canfu adroddiad interim y comisiwn, a gyhoeddwyd fis Rhagfyr 2022, fod problemau sylweddol o ran y ffordd y mae Cymru'n cael ei llywodraethu o fewn yr Undeb ac nad yw parhau â'r sefyllfa bresennol yn opsiwn ymarferol ar gyfer sicrhau sefydlogrwydd a ffyniant. Nododd dri llwybr cyfansoddiadol amgen i Gymru – annibyniaeth, system ffederal ac atgyfnerthu datganoli.
In its interim report, published in December 2022, the commission found significant problems with the way Wales is governed within the Union and that the ‘status quo’ is not a viable or secure foundation for stability and prosperity for Wales. It set out 3 alternative constitutional routes for Wales. These were independence, a federal system and enhancing devolution.
