Natural Justice in GST Adjudication: The Right to Access Relied-Upon Documents vs. Claims of Confidentiality
Introduction: A Fundamental Tension in Tax Proceedings
One of the most pressing concerns emerging from GST adjudication practice today is the selective withholding of documents by revenue authorities — documents that form the very foundation of show cause notices and demand orders. Increasingly, adjudicating officers invoke broad justifications such as "national security," "ongoing investigation confidentiality," or simply "sensitivity" to deny assessees access to materials relied upon against them.
This practice strikes at the heart of fair adjudication. When an assessee is required to respond to serious allegations of tax evasion without having seen the underlying evidence, the entire proceeding is reduced to a formality — a predetermined exercise masquerading as due process. The Supreme Court of India, in V.K. Singh Vs Central Bureau of Investigation & Anr. (2026 INSC 614), has offered crucial guidance on exactly this tension, making it abundantly clear that blanket denial of relied-upon documents — even in matters involving the Official Secrets Act, 1923 — is constitutionally impermissible.
This article examines the principles of natural justice as applicable to GST proceedings, the judicial precedents reinforcing document access rights, and the practical framework that must be followed when genuine confidentiality concerns arise.
The Constitutional and Statutory Basis for Document Access
Audi Alteram Partem: More Than a Latin Phrase
The principle of audi alteram partem — that no person shall be condemned without being heard — is not merely a procedural courtesy. It is a constitutional mandate embedded in Articles 14 and 21 of the Constitution of India. In the context of quasi-judicial proceedings under the GST framework, this principle demands that every piece of material used against an assessee must be disclosed to that assessee, with a genuine opportunity to inspect, challenge, and rebut such material.
Under the Goods and Services Tax regime, proceedings are initiated through a Show Cause Notice (SCN). The SCN typically draws upon investigation reports, statements of third parties, transaction data, and inter-departmental communications. If the assessee is denied access to these foundational documents, the opportunity to respond becomes illusory. A reply drafted in the absence of underlying evidence is inherently incomplete and disadvantaged — not because the assessee lacks merit, but because the assessee has been kept in the dark.
The right to a fair hearing is not satisfied merely by allowing the assessee to submit a written response. It requires that the response be an informed one, based on full disclosure of all adverse material.
The Statutory Mandate Under Criminal Procedure: A Parallel That Cannot Be Ignored
While GST adjudication is a quasi-judicial civil proceeding, the principles governing document access in criminal trials provide an important benchmark — and in fact, the Supreme Court's reasoning in criminal matters has consistently been applied to revenue and administrative adjudications.
Section 207 of the Code of Criminal Procedure, 1973 (CrPC) provides that in proceedings instituted on a police report, the Magistrate shall, without delay, furnish to the accused, free of charge:
- The police report
- The First Information Report recorded under
Section 154 - Statements recorded under
Section 161(3)of all witnesses the prosecution proposes to examine - Confessions and statements recorded under
Section 164 - Any other document or relevant extract forwarded to the Magistrate with the charge sheet under
Section 173(5)
The proviso permits the Magistrate to allow inspection of voluminous documents rather than furnishing physical copies — but this is an exception, not a route for wholesale denial.
The Supreme Court in V.K. Singh Vs Central Bureau of Investigation & Anr. interpreted this provision as follows:
