Cyhoeddwyd adroddiad y Tribiwnlys "Ar Goll mewn Gofal" ym mis Chwefror 2000 a wnaeth 72 o argymhellion sydd wedi bod yn sylfaen ar gyfer gwella gwasanaethau plant yng Nghymru dros y degawd diwethaf.

The Tribunal’s Report “Lost in Care” was published in February 2000 and made 72 recommendations which have provided the foundation on which we have driven improvements to children’s services in Wales over the last decade. Sir Ronald’s report was revolutionary.  It was the catalyst for transformation of services to looked after children through;the establishment of a Children Commissioner,the Children First Programme;the regulation of care settings and the workforce now enshrined in the Care Standards Act 2000;the broader protection of children and strengthening of their voice through arrangements for advocacy and whistle-blowing.
