Oregon Supreme Court Dismisses Case Over Fake AI-Generated Legal Citations

Oregon's Supreme Court took direct aim at AI-generated legal fiction last Friday, tossing out a petition for a writ of mandamus and fining a respondent $500 in a separate case — both casualties of artificial intelligence tools that invented case law out of whole cloth. According to OPB, which first reported the rulings, this is the first time the state's highest court has been forced to confront the problem head-on, though it is far from the first time Oregon courts have seen it. The details in the dismissed petition are particularly damning. The plaintiffs used a product called LegalAI to build their supporting documents, which cited prior cases that simply do not exist and included fabricated quotes attributed to those phantom rulings. When the court ordered them to resubmit, they did — and made it worse. Within 12 hours of receiving that order, they filed a declaration containing at least four additional citations to cases that appear nowhere in the Oregon Appellate Reports or the Oregon Reports. The justices noted that timeline pointedly in their written order. Chief Justice Meagan A. Flynn did not mince words. "We recognize that AI products may seem like an appealing short-cut to legal research and presenting legal arguments," she said in a statement accompanying the rulings. "But when the court has to spend considerable time and effort addressing fabricated legal arguments, it comes at the expense of other cases." That cost is not abstract — every hour clerks and justices spend chasing down nonexistent citations is an hour not spent on cases with real legal arguments. The problem is national in scope and accelerating. Ankur Doshi, General Counsel of the Oregon State Bar, told OPB's *Think Out Loud* in April that fabricated citations are turning up in filings from licensed attorneys and pro se litigants alike — and that many of the people submitting them appear genuinely unaware the AI invented the sources. That ignorance does not reduce the downstream damage: opposing counsel must spend billable hours verifying citations that were never real, driving up legal costs for the other side. Oregon has already seen one of the steepest penalties on record nationally — a $110,000 fine levied against a lawyer in district court. By comparison, lawyers for MyPillow CEO Mike Lindell were fined $3,000 each in federal court last year after submitting filings riddled with AI-generated errors, a figure that critics argued was too low to deter the behavior. What this episode exposes is a structural gap between how AI tools are marketed and how they actually perform under professional-grade scrutiny. Products like LegalAI, ChatGPT, and Claude are designed to produce fluent, confident-sounding text — a feature that becomes a liability when the underlying retrieval fails and the model fills the gap with invented citations that look indistinguishable from real ones. Courts are now effectively serving as the quality-control layer that neither the AI vendors nor, in these cases, the attorneys provided. Whether bar associations, courts, or legislatures will impose formal verification requirements before AI-assisted filings are accepted remains an open question — but Friday's rulings signal that Oregon's Supreme Court has run out of patience waiting for the legal profession to self-correct.
