Why this matter is tracked
False Quotes: Case Law | Fabricated Scalia quote attributed to Liteky; court verified the quote does not appear in the opinion. Outcome: Cases dismissed without prejudice, attorney ordered to pay defendants' attorney fees, referred to Florida Bar.. In May, the court asked Counsel to show cause why they should not be sanctioned for filing briefs with hallucinations - especially since they continued filing hallucinated submissions after being warned about it.In their Answer, Counsel revealed that "specific citations and quotes in question were inadvertently derived from internal draft text prepared using generative AI research tools designed to expedite legal research and brief drafting".In the Order, the court noted that Counsel "was not candid to the Court when confronted about his use of AI, stating that some of these documents were “prepared under time constraints,” when he had nearly two more weeks before the deadline to submit his responses." The judge was also unimpressed by Counsel's attempt to shift the blame to a paralegal.Finally, in the fee dispute order, the court cited this database to point out that its approach to award costs and fees was appropriate, especially given the egregiousness of the claimant's conduct in this case. The judge also took into account "the significant, if indirect, monetary losses that may arise from nonmonetary sanctions in other cases, such as loss of business and loss of reputation, or the monetary loss borne by a client when a motion or even an entire case is adversely decided due to counsel’s misuse of AI."
