Failure to file returns for a continuous period of six months...

Failure to file returns for a continuous period of six months led to cancellation of GST registration. Cancellation order did not specify reasons for retrospective cancellation from registration date, violating principles of natural justice. Proper officer's power to cancel registration from a date cannot be arbitrary, must be informed by reason. Impugned order set aside, matter remanded to Appellate Authority to decide afresh on merits after providing opportunity of hearing, uninfluenced by delay question.
