The Rajasthan High Court has set aside a GST demand of ₹3.13 lakh after finding that the underlying show-cause notice and adjudication order were neither digitally nor physically signed. 

The Bench of  Justice Arun Monga and Justice Ashutosh Kumar held that authentication of GST notices and orders is a mandatory statutory requirement under Rule 26(3) of the CGST Rules, 2017, and that mere electronic generation or a system-generated reference number cannot substitute for a valid signature.

The petitioner had challenged a show-cause notice dated June 13, 2024, and the consequential order dated October 15, 2024, passed under Section 74 of the CGST Act, 2017. The order had confirmed GST demand of ₹3,13,894, along with interest of ₹4,26,002 and an equivalent penalty of ₹3,13,894.

The proceedings originated from an allegation that Mayur Timber had wrongly availed Input Tax Credit (ITC) amounting to ₹3,13,894 without actual receipt of the underlying goods. An electronic FORM GST DRC-01, described as an unsigned summary of the show-cause notice, was uploaded on the GST portal along with the notice dated June 13, 2024.

The adjudicating authority subsequently passed an order on October 15, 2024, confirming the tax demand, interest and penalty. According to the petitioner, however, the order was not served manually or in hard copy and was uploaded on the GST portal under the “Additional Notices and Orders” section rather than the regular “Notices and Orders” section.

The petitioner maintained that it did not become aware of the order until August 2025, when recovery proceedings were initiated against its bank account.

The issue came to a head when the department issued FORM GST DRC-13 under Section 79(1)(c) of the CGST Act on August 20, 2025, to the petitioner’s bank. The bank was directed to recover ₹9,00,820 from the taxpayer’s account.

The petitioner was informed about the pending GST demand by its banker on August 21, 2025. On checking the GST portal, the taxpayer found the impugned order under the “Additional Notices and Orders” heading. The bank account was subsequently provisionally attached, although the authority later released it after the petitioner submitted an affidavit seeking release.

The petitioner approached the High Court, primarily alleging violation of natural justice and denial of an effective opportunity of personal hearing.

The petitioner argued that the entire adjudication was fundamentally defective because the show-cause notice itself was unsigned. It was contended that an unsigned notice lacked legal sanctity and could not form the foundation for a valid adjudication order.

The petitioner further submitted that the order travelled beyond the show-cause notice by confirming interest of ₹4,26,002 and penalty of ₹3,13,894, raising an issue under Section 75(7) of the CGST Act. It was also argued that the mandatory requirement of personal hearing under Section 75(4) had not been complied with.

The petitioner disputed the allegation of wrongful ITC availment and asserted that the goods had actually been received and that ITC had been claimed against valid tax invoices. The petitioner sought setting aside of the proceedings and fresh adjudication in accordance with law.

The department opposed the writ petition, arguing that the show-cause notice and order had been duly uploaded on the common GST portal. According to the department, uploading documents electronically constituted a recognised mode of service under Section 169(1)(d) of the CGST Act.

The department also argued that a registered taxpayer was expected to remain vigilant and regularly access the GST portal. It contended that the documents carried system-generated reference numbers and were generated electronically through the portal, and therefore their authenticity could not be questioned merely because a visible signature was absent.

The revenue further raised the objection that the taxpayer had an effective alternative remedy of appeal under Section 107 of the CGST Act.

The High Court identified the central issue as whether a show-cause notice and adjudication order that bear neither a digital signature nor a physical signature could legally be sustained.

On examination of the documents, the Bench found that the show-cause notice, reminder and impugned order were all devoid of both digital and physical signatures. Although each document carried a reference number generated when it was created, the Court noted that the absence of a signature was conspicuous.

The Court then examined Rule 26(3) of the CGST Rules, 2017. The provision requires notices, certificates and orders covered by the rule to be issued electronically by the proper officer and authenticated through a digital signature certificate, e-signature under the Information Technology Act, 2000, or another mode of signature or verification notified by the Board.

The Bench held that Rule 26(3) is couched in mandatory language. The use of the word “shall”, according to the Court, leaves no room for treating authentication as an optional or dispensable formality.

The Court drew an important distinction between issuance and authentication. Merely generating a document electronically on the GST portal may satisfy the requirement of electronic issuance, but it does not, by itself, satisfy the separate requirement of authentication through a prescribed signature or verification mechanism.

The ruling therefore makes clear that a system-generated GST document cannot automatically acquire legal validity merely because it appears on the electronic tax portal.

The High Court placed particular emphasis on the purpose behind the signature requirement in an electronic tax administration system.

The Bench observed that GST is fundamentally a paperless regime in which documents are created, transmitted and received electronically. In such an environment, a digital signature performs the function traditionally performed by a physical signature.

According to the Court, the rule-making authority replaced the physical signature with digital authentication but did not eliminate the requirement of authentication itself. The signature requirement is therefore not merely a procedural technicality; it is the mechanism through which an electronic document acquires legal existence and binding character.

The Court identified three principal functions of authentication: establishing the authenticity of the document, fixing accountability on the officer responsible for its contents, and providing a safeguard against arbitrary action by demonstrating application of mind by the competent authority.

The revenue’s argument that system-generated reference numbers sufficiently authenticated the documents was expressly rejected.

The Court explained that a reference number or document identification number serves a different purpose. It allows a document to be tracked and catalogued within the electronic system and may indicate when it was created. It does not establish that the proper officer authenticated the document.

The Bench summed up the distinction by observing that “tracking is not authentication.” A reference number, therefore, cannot replace the signature required under Rule 26(3).

The Court went further and held that the absence of a digital or physical signature was not a curable procedural irregularity.

According to the Bench, a show-cause notice or adjudication order that is neither digitally nor physically signed cannot be treated as a valid notice or order in the eyes of law. The defect goes to the root of the proceedings and affects the very authority to proceed against the taxpayer. Consequently, proceedings founded on such documents cannot survive.

This finding forms the central legal takeaway from the judgment and underscores the importance of statutory authentication in GST proceedings.

The Court identified an additional infirmity concerning the manner in which the documents were communicated.

The unsigned notice and order had been uploaded under the “Additional Notices and Orders” heading rather than the regular “Notices and Orders” section. The taxpayer claimed that it remained unaware of the proceedings and discovered the demand only after its banker informed it about the attachment and recovery action.

The Court found that the absence of an authenticated and properly communicated notice appeared to have contributed to confusion regarding the date fixed for personal hearing. The petitioner consequently remained unrepresented when the matter was taken up.

The Bench held that this amounted to denial of the effective hearing contemplated under Section 75(4) of the CGST Act.

The department had argued that the taxpayer should have pursued the statutory appeal under Section 107 rather than invoking writ jurisdiction.

The High Court, however, held that the existence of an alternative remedy does not prevent exercise of writ jurisdiction where principles of natural justice have been violated. In the present case, the Court found that the defects relating to authentication and hearing justified intervention under Article 226 jurisdiction.

The Rajasthan High Court set aside the impugned show-cause notice. As a consequence, the adjudication order dated October 15, 2024, and the subsequent FORM GST DRC-13 recovery notice dated August 20, 2025, were also set aside.

The Court did not adjudicate the substantive merits of the alleged wrongful ITC claim. It granted liberty to the department to initiate proceedings afresh by issuing a duly authenticated show-cause notice and passing a fresh order after providing the taxpayer an effective opportunity of hearing in accordance with law.

The Court expressly clarified that its observations should not be treated as an opinion on the merits of the GST demand and left all substantive issues open for determination by the competent authority.
