Vagueness in a show-cause notice and failure to disclose...

Vagueness in a show-cause notice and failure to disclose material particulars violated natural justice: cancellation of GST registration must rest on objective satisfaction of jurisdictional facts and independent quasi-judicial reasoning, not on investigative dictation. A non-speaking order repeating investigative allegations without identifying tax periods, invoices, suppliers or quantification is invalid. Consequently the impugned notices and cancellation orders were set aside and the petitioner's registration restored; the authority may, if advised, issue a fresh detailed show-cause notice specifying precise allegations, periods, invoices, suppliers and quantification and afford a reasonable hearing.
