The provisions in this section must only be used for modification of contracts during their term and not to circumvent the regulations when a contract ends and a new one needs to be awarded.
Dim ond i addasu contractau yn ystod eu cyfnod, ac nid i osgoi’r rheoliadau pan ddaw contract i ben a bod angen dyfarnu un newydd, y caniateir defnyddio’r darpariaethau yn yr adran hon.
