Himachal Pradesh High Court Strikes Down GST Show Cause Notice Contradicting Unchallenged Advance Ruling

Case Overview

Case Name: Amit Engineers Vs Union of India & Ors.
Court: Himachal Pradesh High Court
Subject Matter: Quashing of Show Cause Notice issued contrary to a binding Advance Ruling under the CGST Act, 2017

Background of the Dispute

The assessee, Amit Engineers, approached the Himachal Pradesh High Court challenging a show cause notice dated 14.02.2025 issued by the Additional Director, Directorate General of Goods and Service Tax Intelligence, Chandigarh (respondent No. 2).

The impugned notice directed the assessee to either:

  1. Pay the demanded amount within thirty (30) days from the date of service of the notice under Section 73(8) of the CGST Act, 2017 read with corresponding provisions of the SGST Act — upon which, proceedings relating to such GST would be deemed concluded as per Section 73(8) of the CGST Act read with respective sections of the IGST Act and SGST Act; or
  2. Submit a written reply along with all supporting documentary evidence intended to be relied upon in defence, while also indicating whether a personal hearing before the adjudicating authority was desired.

The notice further warned that in the event no reply was received within thirty days of receipt, or if the assessee failed to appear for personal hearing when the matter was scheduled, the case would be decided ex parte solely on the basis of the evidence available on record.

Why the Assessee Approached the High Court Directly

Rather than filing a reply to the show cause notice, the assessee chose to invoke the jurisdiction of the High Court under Article 226 of the Constitution of India. The primary ground for this approach was the existence of a valid and binding Advance Ruling dated 11.04.2022, which had classified the assessee's product under a specific GST tariff chapter.

The assessee's contention was straightforward: since the Advance Ruling had never been contested, challenged, or set aside by the department before any forum, it had attained finality and remained binding on the authorities. In such circumstances, the issuance of a show cause notice contrary to that ruling was inherently unsustainable.
