This analysis examines the recent high-profile case of a New York-licensed attorney facing formal judicial sanctions after relying on the generative AI tool ChatGPT for legal research, which generated six non-existent judicial precedents for a personal injury lawsuit against Avianca Airlines.

Live News
In 2019, plaintiff Roberto Mata filed a personal injury claim against Avianca Airlines alleging employee negligence related to injuries sustained from an in-flight serving cart, represented by Steven Schwartz, a New York-licensed attorney with more than 30 years of active practice at Levidow, Levidow & Oberman. In a May 4, 2023 order, Southern District of New York Judge Kevin Castel confirmed that six of the judicial precedents cited in Schwartz’s legal brief were entirely falsified, with fabricated quotes, internal citations, and case details, all sourced directly from ChatGPT. Schwartz stated in sworn affidavits that he had not used ChatGPT for legal research prior to this matter, was unaware of the tool’s potential to generate false content, and accepted full responsibility for failing to independently verify the cited sources. Avianca’s legal counsel first flagged the invalid citations in an April 2023 letter to the court, after failing to locate the referenced cases in official legal databases. Schwartz now faces a formal sanctions hearing scheduled for June 8, and has publicly stated he will not use generative AI for professional work without full, independent authenticity verification going forward. Fellow firm attorney Peter Loduca confirmed in a separate affidavit he had no involvement in the research process and had no reason to doubt Schwartz’s work at the time of filing. Schwartz also submitted court screenshots showing he explicitly asked ChatGPT to confirm the validity of the cited cases, and the tool repeatedly affirmed they were real, claiming they were available on leading legal research platforms including Westlaw and LexisNexis.

Key Highlights
This incident marks the first publicly reported U.S. federal court matter where generative AI “hallucinations” – the production of plausible, contextually appropriate but entirely fabricated content – have resulted in formal disciplinary proceedings against a licensed professional, establishing a critical early precedent for AI-related professional liability. The involved attorney’s 30+ years of industry experience confirms that AI overreliance risk is not constrained to entry-level or less experienced staff, highlighting systemic gaps in current AI use policies across professional services. For the broader market, the incident has triggered immediate reassessments of generative AI use policies across regulated verticals including legal, financial advisory, audit, and compliance services. Professional liability underwriters have already flagged ungoverned AI integration as an emerging high-risk factor, with preliminary industry surveys indicating 28% of U.S. professional services firms are now reviewing existing liability coverage for gaps related to AI output errors. Key confirmed data points include 6 entirely fabricated judicial precedents cited in official court filings, a scheduled sanctions hearing on June 8, and explicit, repeated false confirmations of the fabricated cases’ validity from the generative AI tool.

Expert Insights
Generative AI adoption across professional services has grown at an unprecedented pace over the past 12 months, with 62% of large U.S. professional services firms reporting active deployment of AI tools for research, document drafting, and administrative support as of Q1 2023, per data from the Association of Professional Services Firms. Much of this rapid adoption has been driven by projected 30-40% efficiency gains for routine research and drafting tasks, but until this incident, most corporate AI governance frameworks focused almost exclusively on data privacy and confidentiality risks rather than output integrity. This case has three core implications for market participants across all regulated sectors. First, regulatory and professional standard-setting bodies are likely to accelerate issuance of mandatory AI use guidelines for regulated professions. For financial services specifically, the incident signals the need for enhanced oversight of AI use in high-stakes activities including regulatory filing drafting, due diligence research, and client advisory content, where false or fabricated information could result in material regulatory penalties, client losses, or long-term reputational harm. Second, enterprise risk management frameworks will need to incorporate mandatory multi-layer verification protocols for all AI-generated output used in client-facing or official submissions, rather than relying solely on individual practitioner judgment. Third, the global market for AI validation tools that cross-check generative AI output against verified, authoritative databases is projected to grow 47% annually through 2027, per Grand View Research estimates, as firms invest in proactive mitigation of hallucination risks. Looking ahead, while generative AI remains a high-impact efficiency driver for professional services, firms will increasingly prioritize “human-in-the-loop” governance structures that separate AI use for first-draft generation from final, independent review by subject matter experts with access to verified primary sources. For market participants, the incident serves as a tangible reminder that untested, ungoverned AI deployment carries material operational, compliance, and reputational risks that can fully offset short-term efficiency gains. Professional liability carriers are also expected to introduce targeted AI risk coverage riders over the next 12 to 18 months, as well as premium discounts for firms with documented, auditable AI governance and verification protocols in place.
