The standstill period must end before a contract is awarded and a confirmation of the decision is published (or before returning to an earlier step in the process or abandoning a process).
I fod yn gymhwysol, rhaid i dir y trafodiad fod o fewn safle treth arbennig ar yr adeg pan fo’r contract yn cael ei gwblhau, neu cyn hynny pan fo'r contract wedi'i "gyflawni'n sylweddol".
