The ABA Journal reports that a unanimous three-judge panel of the District of Columbia Court of Appeals struck a Deutsche Bank subsidiary’s appellate brief in a mortgage foreclosure case after finding multiple fake case . The court referred the matter to the District of Columbia Bar’s Office of Disciplinary Counsel.
The ABA Journal, citing Reuters, reports that the D.C. Court of Appeals called the episode a “cautionary tale about the misuse of artificial intelligence” and found multiple nonexistent cases in the subsidiary’s appellate brief. The report says lawyer Loishirl Hall admitted that four had been hallucinated by Google’s tool and should not have appeared in a filing.
According to the ABA Journal’s account of the court’s per curiam opinion, the panel held that responsibility extended beyond Hall to the co-counsel who signed the brief. “Every firm attorney who signed the brief bears some responsibility,” the panel wrote, as quoted in the report.
The court struck the subsidiary’s brief in its entirety and referred the matter to the District of Columbia Bar’s Office of Disciplinary Counsel. Senior Judge Stephen Glickman concurred in the result but wrote separately that the majority had not sufficiently addressed AI use, attorneys’ responsibilities, and potential sanctions. The report says Reuters sought comment from Hall and her former firm but received no response.

Miért számít
The decision gives a concrete example of how courts may treat unverified AI-generated legal research: as a professional-responsibility failure affecting every lawyer who signs the filing. It does not establish a general ban on AI, but it raises the practical cost of deploying generative tools without source checking, attorney review, and clear accountability. The report does not independently confirm the court record or the underlying beyond its account of the opinion.
The ruling treats fabricated authorities as a litigation problem, not merely a technical error. The court said a brief containing fake can misdirect judges, consume court resources, create confusion, and leave a client without credible advocacy while the court investigates.
The source also records an important limit: the panel said it was not trying to stop or discourage lawyers from using AI. Its message, as reported by the ABA Journal, is that attorneys must understand the technology and use it responsibly. A practical implication is that firms need reliable citation verification and human review before filing AI-assisted work.
The report does not independently establish how common similar incidents are, whether the cited cases were generated entirely by AI, or what disciplinary outcome will result. No product access, availability, or pricing information is documented or applicable to this court action.

The disciplinary referral may clarify whether additional sanctions or professional consequences follow. The court’s separate opinion may also shape future guidance on lawyers’ duties when using . The report does not say whether the former firm or attorneys will face specific penalties, whether the mortgage case itself is affected beyond the brief, or which Google tool produced the .
The disciplinary referral is the next formal step identified by the report. Its outcome could indicate how the D.C. Bar evaluates AI-related negligence and whether sanctions extend to lawyers who did not personally generate the false .
Judge Glickman’s separate opinion may provide additional analysis of attorney duties and sanctions. Courts, bar regulators, and law firms may look to the case when developing review procedures for generative-AI-assisted legal research.
The source does not report any final disciplinary finding, additional court sanctions, or independent testing of Google’s tool. Those remain meaningful unknowns.
