Rydym wedi cael ar ddeall bod Llywodraeth y DU yn dymuno trafod â ni, ac â'r Gweinyddiaethau Datganoledig eraill, i weld a oes modd inni gyflawni'r un canlyniadau drwy drafod a chytuno yn hytrach na deddfwriaeth unochrog. Fodd bynnag, nid oes dim yn nhestun y Bil na'r dogfennau ategol sy'n adlewyrchu hyn.
We have been given signals that the UK government wishes to negotiate with ourselves and the other Devolved Administrations to see if we can achieve the same results by discussion and agreement rather than by unilateral legislation. However, there is nothing in the text of the bill or the supporting documentation that reflects this.
