The Gujarat High Court has delivered an important ruling on the responsible use of Artificial Intelligence in tax adjudication, quashing GST cancellation and appellate proceedings after finding that the State Tax Officer had relied on AI-generated case laws, including non-existent and irrelevant judicial authorities.
AI-Generated Case Laws Cannot Replace Independent Legal Reasoning
In a significant judgment dated 20 August 2026, the Gujarat High Court intervened in GST proceedings against Faiz Enterprise, holding that a quasi-judicial order cannot be sustained when the adjudicating authority relies exclusively on unverified AI-generated legal authorities without independently examining their authenticity, relevance and applicability.
The Division Bench comprising Justice A.S. Supehia and Justice Vaibhavi D. Nanavati dealt with the serious consequences of using Artificial Intelligence in judicial and quasi-judicial decision-making without adequate verification.
The Court observed that the impugned order appeared to have been passed by the State Tax Officer by placing reliance exclusively on AI-generated case laws.
The issue came to light when Faiz Enterprise challenged the proceedings and pointed out that one of the judgments relied upon by the officer did not exist. Other authorities cited in the order were also found to contain incorrect citations or legal propositions that were irrelevant to the dispute.
State Tax Officer Admits Use of Artificial Intelligence
Following the Court’s intervention, the State Tax Officer submitted an affidavit tendering an unconditional apology.
The officer admitted that the judicial authorities referred to in the impugned order had been identified using Artificial Intelligence and that the material generated through AI included non-existent and irrelevant judgments.
The officer also explained that he was a probationary officer and had subsequently undergone training relating to the use of AI in drafting adjudication and appellate orders.
The case highlights a critical legal principle: AI can assist legal research, but it cannot replace the independent application of mind required from a statutory or quasi-judicial authority.
Gujarat Tax Department Issues AI Verification Safeguards
An important development following the proceedings was the issuance of detailed instructions by the Additional Commissioner of State Tax regarding the use of Artificial Intelligence by adjudicating and quasi-judicial authorities.
The instructions require officers to independently verify every legal proposition, case law, statutory provision, rule, circular and notification identified through AI before incorporating it into an official order.
Verification must be undertaken from primary and official legal sources.
The safeguards also require officers to:
- Verify the authenticity of every judgment cited in an order.
- Check the current legal status of the judgment.
- Confirm that the cited decision is relevant to the issue under consideration.
- Reproduce the original paragraph where AI has paraphrased the ratio of a judgment.
- Consider judicial authorities cited by the taxpayer.
- Exercise human oversight over AI-generated material.
- Independently apply legal reasoning before reaching a conclusion.
The instructions make it clear that AI-generated material may assist an officer in the reasoning process, but AI output cannot substitute the officer’s own legal analysis and application of mind.
High Court Warns of Contempt Consequences
The Gujarat High Court directed strict compliance with the instructions issued on 18 August 2026.
The Court specifically observed that the instructions incorporated into its order must be followed scrupulously and warned that violation of those safeguards would amount to contempt of court.
This observation assumes considerable importance as government departments and quasi-judicial authorities increasingly use AI-based tools for legal research, drafting and administrative work.
The judgment therefore establishes an important safeguard: technology may support legal decision-making, but responsibility for the correctness of an official order remains with the human authority passing it.
GST Proceedings Against Faiz Enterprise Quashed
Apart from addressing the AI-related issue, the High Court also dealt with the underlying GST dispute.
The Department agreed to reconsider the matter and issue a fresh show cause notice. Consequently, the Court quashed the:
- Show cause notice dated 30 October 2025;
- GST cancellation order dated 15 December 2025;
- Order rejecting the application for revocation;
- Appellate order dated 25 May 2026; and
- Consequential GST APL-04.
The Department was directed to commence fresh proceedings, consider the defence and submissions of Faiz Enterprise and pass a fresh, reasoned order in accordance with law.
Key Takeaway for GST Officers and Taxpayers
The ruling sends a strong message about the limitations of Artificial Intelligence in legal proceedings.
AI tools can significantly improve the efficiency of legal research and drafting. However, AI-generated citations can sometimes contain fabricated authorities, incorrect citations, distorted legal propositions or irrelevant case laws.
For GST adjudication, therefore, every judicial authority and statutory reference generated or identified through AI must be independently verified before being relied upon.
For taxpayers and tax professionals, the judgment also demonstrates the importance of carefully examining the legal authorities cited in GST orders. If an adjudicating authority relies upon a non-existent judgment or materially incorrect legal proposition, the validity of the order may be open to challenge.

Conclusion
The Gujarat High Court’s decision is a significant development at the intersection of GST law, Artificial Intelligence and administrative justice. The ruling reinforces that statutory authorities must independently verify legal material and apply their own judicial mind before passing orders.
The message is clear: AI may assist a legal authority, but it cannot become the authority itself. In tax adjudication, accuracy, verification, reasoned analysis and independent application of mind remain indispensable.
