Gall cael cofnod troseddol yn gynnar mewn bywyd lesteirio potensial person ifanc a golygu na all achub ar gyfleoedd gwaith a chyfleoedd eraill.  Yng Nghymru, rydym wedi ymdrin â chyfiawnder ieuenctid ar sail Confensiwn y Cenhedloedd Unedig ar Hawliau'r Plentyn (CCUHP) ers iddo gael ei fabwysiadu'n ffurfiol gan Weinidogion Cymru yn 2004. Mae ffocws y dull hwn o weithio yn hynod berthnasol i blant a phobl ifanc sy'n troseddu am ei fod yn canolbwyntio ar anghenion y person ifanc yn hytrach na'i ymddygiad.
The acquisition of a criminal record early in life can stifle the potential of a young person, denying them access to areas of employment and other opportunities. Our approach to youth justice in Wales has been underpinned by the United Nations Convention on the Rights of the Child (UNCRC) since it was formally adopted by Welsh Ministers in 2004. The focus of this approach is particularly relevant to children and young people who offend because it concentrates on the needs of the young person rather than their behaviour.
