② Background

Matter of Zareh came before a USA court in February 10, 2026. The case involves the use of ChatGPT in legal proceedings — part of a rapidly growing body of litigation in which courts across common law jurisdictions are grappling with how to respond when AI-generated content finds its way into court filings, submissions, or expert reports without adequate verification by counsel.

③ The AI Issue

had been drafted using artificial intelligence (AI). found that ChatGPT described at least one of the cited Respondent, Omid Zareh, was admitted to the Bar of the cases in the same erroneous manner as counsel, supporting State of New York at a Term of the Appellate Division of the a conclusion that given the “type and trend of error,” they Supreme Court for the Second Judicial Department on August were AI-generated.

④ What the Court Addressed

• The court examined whether AI-generated content in the legal submissions met the standards required by applicable rules of professional conduct and court procedure.
• The use of ChatGPT without independent verification of its output was identified as a core concern — consistent with the approach taken by courts in Mata v. Avianca, Park v. Kim, and other landmark AI hallucination decisions.
• The decision reinforces that counsel bear personal responsibility for verifying every citation, argument, and assertion submitted to a court, regardless of whether AI assisted in their generation.
• Courts in USA continue to develop their approach to AI-generated legal content, with sanctions, referrals, and costs orders all available as remedies for misuse.

⑤ The India Angle

Indian advocates must recognise that USA courts are actively sanctioning lawyers for AI misuse — and Indian courts will follow the same path. The Bar Council of India Rules under the Advocates Act, 1961 impose duties of competence and candour that directly parallel the professional obligations at stake in Matter of Zareh. Rule 14 requires every advocate to uphold the dignity of the judicial office; Rule 22 prohibits knowingly making false statements to the court. Where ChatGPT or any other AI tool generates citations, arguments, or case summaries that are not independently verified, submitting them to any court — trial, High Court, or Supreme Court — risks disciplinary action under Section 35 of the Advocates Act, 1961 and potential contempt proceedings under the Contempt of Courts Act, 1971. Indian courts have inherent power under Section 151 CPC to award costs personally against an advocate whose conduct wastes the court’s time.

⑥ Quick Takeaways

• Courts in USA are actively scrutinising AI-generated content in legal filings — Matter of Zareh adds to that record.
• Verify every AI-generated citation before filing: the duty of candour to the tribunal applies regardless of how the content was generated.
• Indian advocates should treat USA AI hallucination decisions as a preview of how Indian courts will respond as AI misuse reaches Indian courts.
