Florida Court Warns Attorneys: Verify AI-Generated Citations or Face Discipline
Russell v. Mells, Fla. 2d DCA, No. 2D2024-1560, 2025 WL 3533637, Dec. 10, 2025 

More and more, judges are referring attorneys to the bar for discipline for lapses in professional conduct when using generative artificial intelligence to perform legal research without verifying the caselaw cited to the court. Recently, the Second District Court of Appeal in Florida referred appellate counsel to the Florida Bar for citing imaginary legal authorities as if they were law. 

The Court of Appeal addressed two issues. In the first, the court reversed the trial court’s denial of the plaintiff’s motion for leave to amend her complaint. The court then addressed the appellee’s briefing where the attorney cited three cases. Two were actual, published cases but quoted text from other cases. The third citation was to a non-existent case. The court issued an order directing counsel to explain how the case citations and quotes were generated. The attorney explained that all three case citations were the product of computer generated searches which she failed to verify. The attorney went on to state that the errors were not substantive, there was Florida case law that supported the substance of her arguments and there was no intent to mislead the court. The court was unpersuaded. Noting the increasing frequency of attorneys’ reliance on artificial intelligence without verification, the panel was compelled to report the attorney to the Florida Bar. 

Attorneys are required to practice with competence and candor. Those ethical requirements are not excused because a computer program generated faulty or misleading legal analysis, or the attorney did not intend to mislead the court. It is a fundamental duty of all attorneys to read and confirm that the authorities cited stand for the propositions for which they are cited. 

The court closed with the following warning: Efficiency, expertise, and cost savings are some of the reasons why attorneys delegate work and use technological tools such as generative artificial intelligence in representing their clients. But his case is another reminder that an attorney who does so remains responsible for the work product that is generated.

Fla. Workers' Comp Physician Dispensing Ruling Could Produce New Legislative Fight

In a significant decision issued on February 25, 2026, the First District Court of Appeal (DCA) ruled in Publix Super Markets, Inc., et al. v. Department of Financial Services, et al., 430 So. 3d 252 (Fla. 1st DCA 2026), that while injured workers have an absolute right to choose their own pharmacy or pharmacist, that right does not extend to physicians who dispense medications directly to their patients.  Read Blake's article in Insurance Journal: https://www.insurancejournal.com/news/southeast/2026/08/05/880229.htm.

Summary Judgment Secured, Preserving $750,000 in Coverage for Insured in Major Trucking Liability Dispute

Ray Freudiger and Michael A. Roberts (both of Cincinnati) successfully obtained summary judgment on behalf of their client in a coverage dispute arising from a May 19, 2022, motor vehicle accident. A permissive driver operated a box truck for an interstate trucking company and caused severe injuries to two tort victims. Prior to the accident, the insured had procured a commercial auto policy for the trucking company with stated limits of $1,000,000. Following the accident, the insurer initiated a declaratory judgment action asserting that only reduced bodily injury limits of $25,000/$50,000 applied and later counterclaimed, alleging it would not have insured the driver had he been properly submitted for approval under the policy. After extensive discovery, briefing, and oral argument, the court rejected the insurer’s attempt to shift responsibility for the $750,000 in coverage it was legally required to provide for permissive drivers under Ohio law, granting summary judgment in favor of the insured and preserving $750,000 in liability exposure.

Appellate Division Affirms Dismissal of Legal Malpractice Counterclaim Against Martin Law Firm

In Martin v. Loury, 2026 N.J. Super. Unpub. LEXIS 1617 (App. Div. July 15, 2026), Martin Law Firm represented Kirk Loury in an employment matter Mr. Loury filed against his former employer, Concord Equity Group Advisors LLC (“Concord”). The allegations included, among other things, that Loury was not fairly compensated for his employment with Concord. After a bench trial finding in Loury’s favor, the Appellate Division remanded this matter in February 2016 for a second trial. During the second trial, Concord CEO, Lee Argush, testified to lower compensation estimate than first trial. On remand, the second trial judge awarded Mr. Loury the same damages as the first judge, finding Mr. Argush not credible. After the findings during the second trial, Martin Law Firm filed an action against Mr. Loury to recover legal fees and costs of representing Mr. Loury in a second bench trial and Mr. Loury filed a counterclaim against Martin Law Firm for legal malpractice, alleging he should have received an even higher award in the second bench trial. In this allegation, Mr. Loury, through his expert, claimed that Martin Law Firm should have recalled Mr. Loury to the stand to rebut Mr. Argush’s testimony to allege an alternative theory of damages. Mr. Loury’s expert admitted that the second judge already rejected Mr. Argush's theory and accepted Loury's damages theory. The trial court barred Mr. Loury’s expert and dismissed Loury's counterclaim with prejudice before convening the collection trial, and the jury ruled in Martin Law Firm’s favor. Mr. Loury appealed the trial court's pretrial rulings barring his liability expert from testifying in support of his legal malpractice counterclaim, denying his motion for summary judgment on that counterclaim, and denying his motion to amend his counterclaim by adding attorney Joseph A. Martin as a codefendant. In affirming the trial court’s decision, the Appellate Division held that the trial court properly excluded Loury’s expert testimony in the counterclaim against Martin Law Firm because the expert could not explain how calling Loury as a rebuttal witness would have increased damages when the second judge already rejected Mr. Argush's testimony and accepted Loury's damages theory, making the expert’s causation opinion speculative. The Appellate Division also held that the trial court properly denied Mr. Loury's summary judgment motion on his malpractice counterclaim because reasonable minds could differ on whether Mr. Martin's alleged failures would have changed the second judge's damages award, given the judge already found Mr. Argush not credible, creating genuine factual disputes precluding summary judgment. Also, the Appellate Division held that the trial court properly denied Loury's May 2023 motion to add Joseph Martin individually because the statute of limitations expired in February 2022, six years after the 2016 appellate remand when Mr. Loury incurred new legal costs, and relation back did not apply because Mr. Loury knew Mr. Martin's identity throughout and strategically chose to sue only Martin Law Firm in his 2019 counterclaim.
