The Gujarat High Court has set a precedent by invalidating tax adjudication orders that relied solely on artificial-intelligence generated case law, and by issuing comprehensive guidelines to ensure AI-assisted drafting is verified and legally sound.
Background & Facts
The Dispute
The petitioner, Faiz Enterprise (proprietor Mahetar Mahir Farukbai), challenged a series of orders issued by the State Tax Officer, Unit-67, Surat, alleging that the orders were based on non-existent or irrelevant judgments generated by artificial intelligence. The petitioner sought quashing of the show-cause notice dated 30/10/2025, the cancellation order dated 15/12/2025, and subsequent orders, and demanded that a fresh, law-compliant notice be issued.
Key Facts
- The State Tax Officer relied on case law citations that the petitioner contended were AI-generated and did not exist in any legal repository.
- On 13/08/2026 the Court passed an interim order directing the officer to appear and warning of possible disciplinary action.
- The respondent officer submitted an unconditional apology on 19/08/2026, acknowledging the mistake and stating that he had attended an AI-usage training programme on 18/08/2026.
- The Additional Commissioner of State Tax issued formal instructions on 18/08/2026 (No:-CCT/Admin/instructions/2026-27/O.N:-53) prescribing procedures for AI-assisted drafting, emphasizing verification of citations.
- The petitioner’s relief included quashing the show-cause notice (30/10/2025), cancellation order (15/12/2025), order rejecting revocation (dated 10/03/2026, issued on 23/03/2026), appellate order (25/05/2026) and GST APL-04 (26/05/2026), and directing issuance of a fresh notice.

The Legal Issue
What is the legal effect of an adjudicating authority’s reliance on artificial-intelligence generated case law citations that are non-existent or irrelevant, and what procedural safeguards must be observed when AI tools are employed in drafting tax orders?
Arguments Presented
For the Petitioner
The petitioner submitted that the impugned orders were fundamentally flawed because they rested on citations that could not be verified in any official law report. Citing the principle that judgments must be based on correct legal authority, the petitioner argued that the use of AI-generated, unverified case law violates the doctrine of legality and renders the orders void. The petitioner also relied on Section 108 of the GST Act, 2017 to assert that any order passed without proper legal basis is liable to be set aside.
For the Respondent
The respondent maintained that the errors were technical and could be remedied by revising the orders under Section 108 of the GST Act, 2017. The officer emphasized that he had undergone AI-usage training and that the Court’s earlier direction to appear was complied with. The respondent further argued that the reliance on AI did not, per se, invalidate the substantive findings of the tax assessment.
The Court's Analysis
The Court began by observing that the integrity of adjudicatory orders depends on accurate citation of legal authorities. It noted that the State Tax Officer had placed “exclusive reliance on the AI generated case laws,” a practice that the Court could not condone.
"It appears that the impugned order has been passed by the State Tax Officer by placing reliance exclusively on the AI generated case laws." The Court emphasized that AI tools are assistive, not substitutive, and that any citation derived from AI must be independently verified against primary sources. It adopted a purposive approach to statutory interpretation, holding that Section 108 of the GST Act, 2017 empowers the authority to revise orders but does not shield them from being set aside when the foundational legal basis is defective. The Court further elaborated the procedural safeguards:
- AI-generated citations must be cross-checked with official law reports before inclusion.
- The adjudicating authority must record its own reasoning and not merely reproduce AI-derived ratios.
- Failure to comply with these safeguards constitutes misconduct and may attract disciplinary action, including contempt.
- The instructions issued on 18/08/2026 are binding and form part of the legal framework governing future AI-assisted drafting. Applying these principles, the Court found that the orders dated 30/10/2025, 15/12/2025, 10/03/2026, 25/05/2026 and 26/05/2026 were issued on a flawed premise and therefore must be set aside. The Court also recognized the respondent’s willingness to revise the orders but held that a fresh, law-compliant notice must be issued to the petitioner.
The Verdict
The petition succeeded. The Court quashed and set aside the show-cause notice dated 30/10/2025, the cancellation order dated 15/12/2025, the order rejecting revocation dated 10/03/2026 (issued on 23/03/2026), the appellate order dated 25/05/2026 and the GST APL-04 dated 26/05/2026. It directed the respondent authority to issue a fresh notice in accordance with law and to strictly adhere to the AI usage instructions dated 18/08/2026. Non-compliance will amount to contempt of court.
What This Means For Similar Cases
AI Reliance Must Be Verified
- Any case law or statutory provision identified through AI must be cross-checked with official sources before being cited.
- Officers must record their own legal reasoning; AI-generated ratios cannot be reproduced verbatim without verification.
Disciplinary Liability for Misuse
- Failure to follow the AI usage instructions constitutes misconduct and may attract disciplinary action, including contempt.
- The ultimate responsibility for the correctness of an order rests with the issuing authority, irrespective of the technology employed.
Section 108 GST Act Can Revise, Not Immunise
- While Section 108 of the GST Act, 2017 allows revision of orders, it does not protect orders that are based on non-existent legal authority.
- Practitioners must ensure that any revision under Section 108 is predicated on sound legal citations.
