This ground does not apply where the individual has received an immunity from prosecution letter in connection with the conduct (or has been granted similar immunity outside of the UK).
Nid yw'r rheswm hwn yn berthnasol os yw'r unigolyn wedi derbyn llythyr sy'n ei eithrio rhag cael ei erlyn mewn cysylltiad â'r ymddygiad (neu os yw wedi'i eithrio mewn ffordd debyg y tu allan i'r DU).
