A case can be withdrawn or agreed at any stage, however if it remains unresolved, a case can only be concluded by a tribunal hearing.
Gall achos gael ei dynnu’n ôl neu ei gytuno arno ar unrhyw adeg, fodd bynnag, os bydd yn parhau heb ei benderfynu, dim ond drwy wrandawiad tribiwnlys y gellir penderfynu ar achos.
