M/S ARMOUR SECURITY (INDIA) LTD. V. COMMISSIONER, CGST, DELHI EAST COMMISSIONERATE & ANR 2025 INSC 982:

DATE: 14/08/2025

COURT: Supreme Court of India

BENCH: Justice J.B. Pardiwala and Justice R. Mahadevan

FACTS:

The case arose from a Special Leave Petition (SLP) challenging the judgment of the Delhi High Court dated 07.02.2025 in W\.P.(C) No. 1082 of 2025, whereby the High Court dismissed a writ petition filed by the petitioner company. The petitioner, a public limited company engaged in providing security services and registered under the GST Act, had earlier received a show cause notice dated 18.11.2024 under Section 73 of the CGST Act for the tax period April 2020–March 2021, demanding Rs. 1.24 crore on grounds of under-declared turnover and excess ITC claims. Subsequently, on 16.01.2025, the GST authorities conducted a search under Section 67(2) at the petitioner’s premises, seizing electronic gadgets and documents, and issued summons under Section 70 to the directors of the company to produce relevant documents.

On 23.01.2025, another summons under Section 70 was issued to one of the directors for producing documents, to which the petitioner responded by highlighting that it was already under investigation by another authority (Respondent No. 2) on similar issues, including ITC from cancelled suppliers, and requested release of seized material. Aggrieved, the petitioner filed a writ before the Delhi High Court contending that Respondent No. 1 lacked jurisdiction in view of Section 6(2)(b) of the CGST Act, as another authority was already investigating. The High Court dismissed the writ, holding that Section 6(2)(b) does not bar search or investigation, since summons are only for information gathering and not equivalent to assessment proceedings under Sections 73 or 74 of the Act.

ISSUES:

The primary issue before the Supreme Court was whether, under the CGST Act, parallel or overlapping inquiries, investigations, or proceedings can be initiated by different tax authorities (Central or State) against the same assessee in respect of the same subject matter, and if such duplication violates the statutory scheme and principles of fairness.

JUDGEMENT WITH REASONING:

The Court held that once the subject matter crystallizes through a show cause notice issued by one authority, no other tax authority can assume jurisdiction over the same matter. Any subsequent show cause notice covering an already-noticed liability must be quashed. To prevent duplication and conflict, the Court laid down detailed guidelines governing how authorities should coordinate when inquiries overlap. The SLP was accordingly disposed of.

The Court reasoned that the CGST Act envisages a regime of cross-empowerment between Central and State authorities, making it essential that one authority’s proceedings inure to the benefit of all. Once a show cause notice is issued, the subject matter stands crystallized, and further action by another authority would create prejudice, harassment, and inefficiency, undermining the legislative intent of the GST framework. The Court emphasized that officers exercising power must communicate across jurisdictions to ensure coordination and avoid duplication, since the Act vests authority in “proper officers” to issue orders binding upon the taxpayer.

Further, the Court highlighted the need for safeguards: taxpayers must initially comply with summons or notices, but if they find that a parallel inquiry is ongoing, they must inform the subsequent authority. Thereafter, it becomes the duty of both authorities to verify and decide who should proceed, failing which the authority that initiated action first will retain jurisdiction. This approach balances the taxpayer’s right against overlapping proceedings with the government’s need to conduct thorough investigations. Finally, the Court stressed that effective IT infrastructure and real-time data sharing between Central and State departments is vital to prevent duplication, minimize hardship, and uphold cooperative federalism within the GST regime.

ANALYSIS:

This case is significant as it addresses the long-standing ambiguity in the GST framework regarding parallel jurisdiction of Central and State tax authorities. By holding that once a show cause notice is issued, the “subject matter” stands crystallized, the Supreme Court has clarified that duplication of proceedings by multiple authorities is impermissible. The Court’s guidelines establish a procedural balance: taxpayers are required to initially comply with summons, but they are also protected from harassment caused by overlapping inquiries. This ruling thus strengthens procedural fairness under the GST regime while ensuring that tax administration does not devolve into conflicting actions by different wings of the Department.

At the same time, the judgment underscores the legislative intent of cooperative federalism embedded in the GST Act. By directing authorities to communicate and share intelligence, the Court recognized the necessity of cross-empowerment while preventing its misuse. The emphasis on developing robust IT infrastructure and real-time data sharing reflects the Court’s concern with both systemic efficiency and taxpayer rights. In essence, the judgment harmonizes revenue interests with safeguards against arbitrary exercise of power, and it lays down a practical framework that can guide future tax investigations across jurisdictions.
