State of play.

  • Sanctions for AI hallucinations are now a multi-jurisdictional enforcement pattern with escalating repeat-offender exposure. Judge Wang's second sanction against Kachouroff—$5,000 for a materially incorrect citation, following a $3,000 Rule 11 fine for approximately 30 defective citations in the same case—establishes that courts treat prior sanctions as aggravating, not mitigating, and will not accept human-error explanations where metadata contradicts counsel's account .
  • Federal courts are extending AI accountability beyond citation errors into discovery workflow. The S.D. Indiana's White v. Walmart order holds that exclusive AI reliance in discovery review violates the FRCP good-faith meet-and-confer obligation—framing AI-driven (as distinct from AI-assisted) discovery as a sanctionable abdication of professional responsibility .
  • ABA Formal Opinion 512's "reduced verification for familiar tools" standard is under direct attack. A Stanford study cited in the opinion itself documents 17–33% hallucination rates in leading legal AI platforms, and critics argue the opinion's logic collapses given that AI systems change continuously .
  • Client-side AI misuse is a distinct privilege and liability vector that counsel must proactively manage. United States v. Heppner (S.D.N.Y.) held that AI-generated documents created outside counsel's direction are not privileged, and published advisory guidance now frames client AI use as a client management obligation—not merely a technology policy question .
  • For counsel advising law firms, legal departments, or individual practitioners, the practical baseline is that AI governance failures are producing sanctions, resignations, and privilege waivers simultaneously across courts and jurisdictions—ethics opinion compliance is a floor, not a defense, and repeat-offender patterns are drawing escalating judicial responses.

Where things stand.

  • Hallucination sanctions have a developing per-error formula. Oregon's Ringo v. Colquhoun formula ($500–$1,000 per AI error) is now being cited in federal rulings; Oregon federal courts have imposed penalties exceeding $100,000 in Green Building Initiative v. Peacock (2025); the Ghiorso case is the current appellate benchmark .
  • The "no-AI policy" defense does not insulate firms from staff violations. Ghiorso had an explicit no-AI drafting policy; staff used AI anyway; the court sanctioned him regardless—establishing that policy existence without verifiable enforcement is insufficient .
  • Repeat sanctions in the same case are on the record. The Kachouroff/DeMaster pattern in the Lindell litigation—two separate sanctions proceedings, contradictory excuses disproven by metadata—signals that courts treat prior sanctions as aggravating, not mitigating, factors .
  • Government attorneys are not exempt. New Orleans city attorneys and a DOJ assistant U.S. attorney have resigned following sanctions proceedings over AI-generated fake citations, extending the exposure beyond private practice .
  • The Seventh Circuit has admonished a former immigration judge for submitting fabricated citations in a brief, signaling that appellate courts across circuits are treating this as a disciplinary matter, not merely a procedural one .
  • ABA Formal Opinion 512 / Mississippi Ethics Opinion 267 permit reduced verification for "familiar" tools—a standard critics argue is internally contradicted by the Stanford hallucination data the opinion itself cites, and which does not account for continuous model updates .
  • AI-driven discovery review is categorically distinct from AI-assisted review under emerging doctrine. White v. Walmart draws the line at exclusive delegation: AI can inform attorney judgment but cannot replace the independent review required for good-faith FRCP compliance .
  • Client use of consumer AI creates privilege exposure that counsel must proactively address. United States v. Heppner provides judicial backing for the proposition that uploading privileged materials to ChatGPT or Claude waives privilege; states including Pennsylvania and New York have enacted laws restricting AI impersonation of licensed professionals .
  • OpenAI faces civil and criminal scrutiny over failure-to-warn obligations in the Tumbler Ridge school shooting and the Florida State University shooting—a separate but adjacent liability vector that will shape how AI companies define "imminent risk" thresholds and what disclosure obligations attach .

Latest developments.

  • Judge Wang imposes a second $5,000 sanction on Kachouroff in the Lindell defamation case for a materially incorrect citation, rejecting a human-error explanation and citing precedents reaching $15,000 for fictitious citations—the second Rule 11 sanction in the same case following a $3,000 fine for approximately 30 defective citations in July 2025; Lindell and co-counsel DeMaster escaped penalty on this round, though DeMaster faced consequences in the earlier proceeding .

Active questions and open splits.

  • What verification standard satisfies competence under ABA Model Rule 1.1? ABA Opinion 512 permits reduced verification for familiar tools, but the Stanford hallucination data (17–33%) and continuous model updates make "familiarity" an unstable proxy. No court has yet defined what independent verification requires in quantitative terms .
  • Where is the line between AI-assisted and AI-driven work product? White v. Walmart draws it at exclusive delegation in discovery review, but the principle has not been extended to brief drafting, contract review, or due diligence workflows—each of which presents the same substitution risk .
  • Does a no-AI office policy insulate the supervising attorney? Ghiorso's experience says no—but courts have not articulated what enforcement infrastructure would satisfy supervisory responsibility under Model Rule 5.1 .
  • What is the privilege status of AI-assisted work product created at counsel's direction? Heppner addressed client-generated AI documents outside counsel's direction; the privilege analysis for attorney-directed AI use in drafting remains unsettled .
  • Do repeat sanctions in the same case trigger bar discipline referrals? The Kachouroff/DeMaster pattern—two sanctions, contradictory excuses, metadata-disproven explanations—raises the question of whether courts will escalate to disciplinary referrals or whether monetary sanctions remain the ceiling .
  • Will sanctions formulas converge across jurisdictions? Oregon's per-error formula is being cited federally, but Arizona, the Seventh Circuit, and DOJ-adjacent proceedings have not adopted a uniform metric—creating inconsistent exposure calculations for the same conduct .
  • Do AI companies have a duty to warn law enforcement of threats identified in user interactions? The Tumbler Ridge and FSU shooting litigations will test whether OpenAI's internal "imminent and credible risk" threshold is legally adequate, and whether a duty to warn runs to third parties .

What to watch.

  • Whether Judge Wang or other courts escalate from monetary sanctions to bar discipline referrals in repeat-offender AI citation cases—the Kachouroff pattern is the most visible test case.
  • Whether any court articulates an affirmative verification protocol—specific steps, not just a standard—that satisfies Rule 1.1 competence for AI-assisted work product.
  • Whether the ABA or any state bar revises the "familiar tool / reduced verification" permission in light of published criticism and the Stanford hallucination data.
  • Outcome of the Tumbler Ridge victim family lawsuit and Florida AG's criminal scrutiny of OpenAI—the first cases to test whether AI companies bear a duty to warn third parties of threats identified in user sessions.
  • Whether malpractice insurers begin conditioning coverage or pricing on documented AI governance protocols, creating a market-driven verification standard independent of bar guidance.
  • Whether the White v. Walmart AI-in-discovery holding is adopted by other district courts or generates a circuit-level ruling on FRCP good-faith obligations.

UN releases 2026 International AI Safety Report warning of enormous benefits and existential risks

The United Nations released the International AI Safety Report 2026, a comprehensive assessment concluding that advanced artificial intelligence presents both transformative opportunities and escalating dangers. The report, led by the UN agency for digital technology, finds that AI can accelerate development in health, education, and financial services in developing nations while simultaneously enabling cyberattacks, deepfake fraud, non-consensual intimate imagery, and biological weapon design. The core finding: AI capabilities in critical fields like biological research are advancing faster than governance frameworks, creating a dangerous gap between what is technologically possible and what remains safe.

Arizona Attorney Maren Bam Faces Sanctions for Bogus AI-Generated Quotes in Employment Case

A federal judge in Arizona is weighing fee sanctions against attorney Maren Bam for submitting a brief laced with fabricated legal citations and AI-generated quotations in an employment discrimination case. U.S. Magistrate Judge Alison S. Bachus identified the violations in Bam's plaintiff's opening brief in a Phoenix Suns discrimination matter, where 19 of the brief's legal citations were generated by artificial intelligence. Only 5 to 7 of those cases actually existed or supported the propositions attributed to them. The brief also contained fake quotations falsely attributed to Arizona federal judges. Bam, a Washington State attorney operating pro hac vice in the District of Arizona, runs a nationwide Social Security disability practice.

Connecticut Supreme Court Threatens Sanctions Against GLG Law for AI Hallucination Errors

The Connecticut Supreme Court has ordered GLG Law LLC and one of its attorneys to appear before the justices next month to face potential sanctions for submitting court documents in two separate cases containing fabricated case law generated by artificial intelligence. The order, issued Tuesday, marks a significant escalation in judicial enforcement against AI misuse in legal practice and represents the first direct action by Connecticut's highest court against a local firm on these grounds.

Top Law Firm Sullivan & Cromwell Sanctioned for AI Hallucinated Citations in Court Filing

Sullivan & Cromwell LLP apologized in April 2026 after filing a motion in U.S. Bankruptcy Court in Manhattan containing approximately 30 fabricated legal citations generated by artificial intelligence. The document, submitted to Judge Martin Glenn, included "hallucinated" case references that did not exist. The errors were discovered by opposing counsel. Partners at the firm, which bills over $2,000 per hour, issued a formal letter of regret on April 18, 2026, and faced professional sanctions and judicial reprimand.

In-House Counsel Whistleblower Cases Highlight Severe Consequences for Rare Corporate Snitches

In-house counsel are filing whistleblower complaints against their employers at a documented but still rare rate in 2026, marking a significant shift in corporate legal culture. These internal lawyers—who occupy fiduciary roles that historically discourage disclosure—are pursuing False Claims Act qui tam suits and SEC Whistleblower Program complaints alleging fraud. Those who do report face severe consequences: job termination, industry blacklisting, and legal harassment. Firms like Phillips & Cohen are actively representing these in-house relators in national litigation.
