The Himachal Pradesh High Court has quashed a Goods and Services Tax (GST) show cause notice issued against a manufacturer, holding that the notice was unsustainable because it directly conflicted with an earlier Advance Ruling that had already attained finality between the parties.

The Bench of Justice Vivek Singh Thakur and Justice Ranjan Sharma has observed that  once the Advance Ruling had attained finality between the parties, there was “nothing required to be adjudicated” on the same issue and the notice had to be treated as “non-est.”

The dispute arose after the Additional Director of the DGGI issued a show cause notice dated February 14, 2025, demanding payment under Section 73(8) of the Central Goods and Services Tax (CGST) Act along with corresponding provisions of the State GST law. The notice directed the petitioner to pay the demanded amount within 30 days and warned that failure to respond could result in ex parte proceedings.

The notice also required the petitioner to submit evidence in support of its defence and indicate whether it sought a personal hearing before adjudication.

Instead of filing a reply before the adjudicating authority, the petitioner approached the High Court contending that the issue had already been conclusively settled through an Advance Ruling dated April 11, 2022, which had never been challenged by the GST authorities.

The earlier Advance Ruling concerned the classification of “Roof Mounted AC Package Units” manufactured specifically for Indian Railways as per designs and layouts provided by the Railway Design and Standards Organisation (RDSO).

The Authority for Advance Ruling had held that the products would fall under Chapter 86.07 of the GST Tariff because they were manufactured exclusively for Indian Railways and supplied nowhere else.

The ruling further clarified that it would remain valid unless declared void under Section 104(1) of the CGST Act.

The department argued that the petitioner should first have responded to the show cause notice and then availed the appellate remedy available under the CGST Act if any adverse order was passed.

The department maintained that the writ petition was premature and that the statutory adjudication mechanism should not have been bypassed.

Rejecting the department’s objections, the High Court observed that the Advance Ruling had neither been challenged nor questioned before any forum and had therefore attained finality. The Bench held that such rulings are binding on the authorities.

The Court noted that although parties are generally directed to respond to show cause notices and pursue statutory remedies, the present matter was different because the notice itself lacked any legal foundation in view of the binding Advance Ruling.

The Bench observed that compelling the petitioner to undergo adjudication proceedings despite the settled legal position would serve no purpose.

Invoking its powers under Article 226 of the Constitution, the High Court held that the case was fit for judicial interference and accordingly quashed the show cause notice dated February 14, 2025.

The writ petition was allowed and disposed of along with pending applications, if any.
