Gujarat High Court Quashes GST Orders Based on AI-Generated Case Law, Orders Fresh Proceedings

The Gujarat High Court has quashed GST registration-cancellation and appellate proceedings against Faiz Enterprise after finding that the State Tax Officer had relied on artificial-intelligence-generated case law that either did not exist in the form cited or did not deal with the issue. A Division Bench of Justice A.S. Supehia and Justice Vaibhavi D. Nanavati delivered the judgment dated 20 August 2026 in R/Special Civil Application No. 10123 of 2026 (Neutral Citation 2026:GUJHC:53490-DB). The court also directed that the Gujarat State Tax Department's new instructions on AI use in quasi-judicial work be followed strictly, and said that any violation would amount to contempt of court.

The GST orders under challenge

The petitioner, Faiz Enterprise through its proprietor Mahetar Mahir Farukbhai, challenged proceedings taken by the State Tax Officer, Unit-67, Surat. The judgment records the following sequence:

• Show-cause notice dated 30 October 2025
• Order cancelling GST registration dated 15 December 2025
• Order rejecting the revocation application, dated 10 March 2026 and issued on 23 March 2026
• Appellate order dated 25 May 2026, with the consequential GST APL-04 dated 26 May 2026

Before the High Court, the taxpayer pointed out that the judgments cited in the tax order did not support the propositions for which they had been used. The judgment refers to three authorities whose citation and ratio did not match what the order attributed to them: State of Gujarat v. Aarbee Structures Pvt. Ltd., 2024 (4) TMI 951; M/s. Sri Vinayaga Agencies v. Assistant Commissioner, 2023 (5) TMI 106; and Jyoti Tar Products Pvt. Ltd. v. Deputy Commissioner, 2024 (7) TMI 512.

What happened at the 13 August hearing

In its oral order dated 13 August 2026, the Bench noted the submission of the petitioner's advocate that the officer had relied on case laws which "do not even remotely deal with the issue", and observed that the impugned order appeared to have been passed "by placing reliance exclusively on the AI generated case laws". It asked the Assistant Government Pleader to take instructions, warned that it would otherwise seek the presence of the officer who passed the order, and listed the matter on 20 August 2026 at the top of the board.

On 20 August, the court was told that the officer, a probationary officer, had tendered an unconditional apology for citing judgments generated through AI and had since attended a training programme on AI use. The State also placed on record administrative instructions dated 18 August 2026 issued by the Additional Commissioner of State Tax (Admin), Gujarat State, to all Joint Commissioners.

The five safeguards in the 18 August 2026 instructions

The Bench incorporated these instructions in its judgment. In substance, they require:

1. Independent verification: any case law, statutory provision, rule, circular or notification identified through AI must be verified from primary official sources before it is used in an order.
2. Accurate citation and current status: officers must confirm the citation and relevance of a higher-forum judgment, reproduce the relevant extract, check the authenticity of the source and confirm the judgment has not been overruled. If an AI tool paraphrases a ratio, the officer must locate the original paragraph and reproduce it verbatim before relying on it.
3. Taxpayer's authorities: judgments cited by the taxpayer must be considered and discussed, and reasons recorded if a judgment is found not applicable.
4. Human oversight: use of AI, open-source or other technological tools in adjudication must be accompanied by appropriate human oversight, as such tools are not always reliable.
5. Independent reasoning: the order must record the officer's own application of mind; AI output may assist reasoning but cannot substitute it.

The instructions add that failure to follow them, including passing orders based on unverified AI content, will amount to misconduct and may attract disciplinary action.

Orders quashed and fresh proceedings allowed

The High Court quashed and set aside the show-cause notice of 30 October 2025, the cancellation order of 15 December 2025, the revocation-rejection order of 10 March 2026, the appellate order of 25 May 2026 and the GST APL-04 of 26 May 2026. The respondent authority is to issue a fresh notice, consider the petitioner's reply and defence, and pass a reasoned order in accordance with law. All rights and contentions of both sides are left open.

The Bench directed that the 18 August 2026 instructions "shall be scrupulously followed, and any violation of the instructions would amount to contempt of this Court".

What this means for GST practitioners

• Check every citation in an adverse order. Match the case name, TMI or other citation, court and the quoted paragraph against the original judgment. A mismatch is a strong ground in appeal or writ.
• Put your own authorities on record. Instruction (iii) requires officers in Gujarat to discuss judgments cited by the taxpayer and give reasons for rejecting them. An order that ignores them is open to challenge.
• Use the Gujarat instructions as a benchmark. They bind State GST officers in Gujarat, but the principles of verification and independent reasoning are useful when reviewing orders from any authority.
• Apply the same discipline to your own drafts. Replies, appeals and petitions prepared with AI tools should be checked against primary sources before filing.

The ruling does not bar AI in tax administration. It fixes responsibility on the human officer: AI may assist research, but every authority relied on must be verified and the reasoning must be the officer's own.
