Cyhoeddwyd adroddiad yr ymchwiliad barnwrol eang i gam-drin plant yng Ngogledd Cymru, dan gadeiryddiaeth Syr Ronald Waterhouse, yn y flwyddyn 2000. “Ar Goll Mewn Gofal” oedd ei deitl, ond caiff ei adnabod yn aml fel Adroddiad Waterhouse. Fe’i comisiynwyd (cyn dyddiau datganoli) gan Ysgrifennydd Gwladol Cymru ar y pryd, sef y Gwir Anrhydeddus William Hague, a’i gyflwyno i’r Gwir Anrhydeddus Paul Murphy, fel yr Ysgrifennydd Gwladol yn 2000. Roedd yn cynnwys argymhellion helaeth ar gyfer amddiffyn plant yn well, ac aeth Llywodraeth Cymru ymlaen i roi amryw o’r argymhellion hyn ar waith. Mae’r Prif Weinidog wedi cyhoeddi ymchwiliad i edrych i ba raddau y cyflawnodd Adroddiad Waterhouse yr hyn yr oedd i fod i’w wneud. O ystyried mai Llywodraeth y DU a gomisiynodd Adroddiad Waterhouse ac mai i Lywodraeth y DU y’i cyflwynwyd, a bod yr ymholiadau yn ymdrin â materion sydd heb eu datganoli yn ogystal â materion datganoledig, mae’n ymddangos bod y cam hwn yn gwbl briodol.
The report of the extensive judicial inquiry chaired by Sir Ronald Waterhouse into child abuse in North Wales – entitled “Lost in Care” often known as the Waterhouse Report - was published in 2000.  It was commissioned (before devolution began) by the then Secretary of State for Wales, the Rt. Hon. William Hague, and reported to the Rt. Hon. Paul Murphy, as Secretary of State, in 2000.  It made extensive recommendations for improving child protection, many of which were subsequently implemented by the Welsh Government.   The Prime Minister has announced an inquiry to examine the extent to which the Waterhouse Report did what it was supposed to do.  Given that Waterhouse was commissioned by the UK Government and reported to the UK Government, and that lines of enquiry cover non-devolved as well as devolved issues, this action seems entirely appropriate.
