Mae’r Mesur wedi gosod dyletswydd ar Weinidogion i roi sylw dyledus i’r CCUHP a’i Brotocolau Dewisol wrth wneud penderfyniadau ynghylch deddfwriaeth a pholisïau arfaethedig a phan fyddwn yn adolygu deddfwriaeth a pholisïau cyfredol. Daeth cam cyntaf y sylw dyledus i rym ar 1 Mai 2012.
The Measure has placed a duty on Ministers to have due regard to the UNCRC and its Optional Protocols when making decisions about proposed legislation and policies and when we review  existing legislation and policies. The first stage application of due regard came into force on 1 May 2012.
