In contrast to other joint committee arrangements, CJCs are independent corporate bodies which can employ staff, hold assets and budgets, and undertake functions.
Yn wahanol i drefniadau cyd-bwyllgorau eraill, mae CBCau yn gyrff corfforedig annibynnol sy’n gallu cyflogi staff, dal asedau a chyllidebau, a chyflawni swyddogaethau.
