Statutory appeal bars writ interference where no exceptional circumstances, jurisdictional defect, or prima facie vires issue is shown.

An efficacious statutory appeal under the CGST Act ordinarily bars direct writ intervention, and the Court reiterated that bypassing the appellate remedy is justified only in exceptional circumstances. It also accepted that GST intelligence officers may be assigned functions as proper officers for inquiry and adjudication, so the jurisdictional objections to summons and proceedings failed. The challenge to the Circulars and related vires arguments was rejected because no strong prima facie case for constitutional or delegated-legislation interference was shown. The result was that the writ court declined interference and left the petitioners to pursue the statutory appellate remedy.

Issues: (i) Whether the writ petition was maintainable in view of the statutory remedy of appeal under section 107 of the CGST Act, 2017 and the absence of exceptional circumstances; (ii) whether the challenge to the jurisdiction of the adjudicating and investigating officers was sustainable; (iii) whether the challenge to the Circulars and related vires objections disclosed any prima facie ground warranting writ interference.

Issue (i): Whether the writ petition was maintainable in view of the statutory remedy of appeal under section 107 of the CGST Act, 2017 and the absence of exceptional circumstances.

Analysis: The petitioners had an efficacious statutory appeal against the adjudication order, yet approached the writ court directly. The Court noted that interference in writ jurisdiction despite an alternative remedy is confined to exceptional cases and that no such exceptional circumstance was made out. The proceedings had also been preceded by investigation, seizure, notice, reply and hearing, and the impugned order was reasoned.

Conclusion: The writ petition was not maintainable on this ground and the Court declined to bypass the statutory appellate remedy.

Issue (ii): Whether the challenge to the jurisdiction of the adjudicating and investigating officers was sustainable.

Analysis: The Court accepted the view that officers of the GST intelligence set-up could be assigned functions as proper officers for the purposes of inquiry and adjudication under the Act. Reliance was placed on prior decisions holding that notifications and circulars validly empowered such officers to issue summons and initiate proceedings, and the objections based on parallel authority or lack of proper officer status were found without substance.

Conclusion: The jurisdictional challenge failed and was rejected.

Issue (iii): Whether the challenge to the Circulars and related vires objections disclosed any prima facie ground warranting writ interference.

Analysis: The Court held that a challenge to vires must be made at the earliest point of time and must disclose a strong prima facie case. On the facts, the petitioners failed to show any such case, especially in view of the investigation materials and the settled principles governing scrutiny of constitutional and delegated-legislation challenges. The Circulars were not found vulnerable on the record before the Court.

Conclusion: The vires challenge did not warrant interference and was rejected.

Final Conclusion: The Court declined to exercise writ jurisdiction, leaving the petitioners to pursue the statutory appellate remedy against the adjudication order.

Ratio Decidendi: Where an efficacious statutory appeal is available and no exceptional circumstance or prima facie jurisdictional or vires infirmity is shown, the writ court should not interfere with a reasoned GST adjudication order.
