GST appellate procedure requires a hearing before disposal,...

GST appellate procedure requires a hearing before disposal, including where limitation, signatory authority or pre-deposit is disputed. Delay may be condoned on sufficient cause within the further statutory period; no separate affidavit is prescribed. A company's authorised signatory may validate an appeal under a general power of attorney, and deficient proof of authority is curable. In interest-only appeals, alternative computations do not constitute an admitted liability, and statutory pre-deposit is confined to tax in dispute. Interest on differential GST runs from invoice-based tax liability despite customer non-reimbursement; cum-tax valuation applies only where the stated value includes tax. Interest demands for delayed GSTR-3B payments must account for documented interest already paid through reasoned adjudication.
