Mae’r OS hefyd yn gwneud cywiriadau technegol i Ddeddf Crwneriaid a Chyfiawnder 2009 a Deddf Crwneriaid (Gogledd Iwerddon) 1959, ond gan nad oedd modd i’r diwygiadau hyn gael eu gwneud gan Weinidogion Cymru (gan eu bod y tu allan i’r cymhwysedd datganoledig) nid oes angen cymeradwyaeth ar eu cyfer.
The SI also makes technical corrections to the Coroners and Justice Act 2009 and the Coroners Act (Northern Ireland) 1959, but since these amendments could not be made by the Welsh Ministers (as they are outside devolved competence) they do not require approval.
