Where registration had already been cancelled, adjudication could continue only on physical service of the show cause notice because the taxpayer could not be expected to access the Common Portal; service merely by electronic upload was therefore inadequate.

The HC accordingly set aside the adjudication order and remitted the matter for fresh adjudication after physical service of notice, supply of relied-upon documents, and grant of due hearing.
