JMOR Properties, LLC v. Artist Alley Townhomes, LLC

District Court of Appeal of the State of Florida, Fourth District · Fla. 4th DCA · Florida bar guidance

Conduct

Counsel filed an AI-drafted certiorari petition with a non-existent Fourth DCA case and false claims about the court's jurisdiction, saying he filed the wrong draft.

Consequence

Counsel referred to The Florida Bar for consideration of disciplinary proceedings; the court found the revised petition he alleged he intended to file omitted controlling adverse law.

Lesson

The court held a wrong-draft explanation did not excuse unverified citations, and found that failing to discover controlling law showed a competence violation.

Citation
JMOR Props., LLC v. Artist Alley Townhomes, LLC, No. 4D2026-1787 (Fla. 4th DCA Aug. 12, 2026) (per curiam) (on order to show cause)
Decided
August 12, 2026

Summary

Barry M. Leff of the Law Offices of Barry M. Leff, P.A. filed a certiorari petition for JMOR Properties, LLC seeking review of a Palm Beach County order vacating a clerk's default. The Fourth District described the petition as "riddled with false citations and arguments," including the unsupported assertion that the court has "repeatedly entertained, and granted, certiorari review of orders vacating clerk's defaults." The petition cited a non-existent case attributed to the Fourth District and other cases that did not support that proposition; in fact the court lacks certiorari jurisdiction over such orders, as it has held since 1979. On June 30, 2026, the court dismissed the petition and ordered counsel to show cause. His July 10, 2026 response acknowledged the false citations, identified more, and accepted responsibility. The court recounted that, according to counsel, his normal process is to have AI software research and draft the initial document and then verify every citation, and that he "allegedly did that in this case," but "while he was making final edits, he inadvertently worked from the wrong version and ended up filing the AI's initial draft." He attached what he alleged was the revised petition he had intended to file.

What sanction did the court impose?

In a per curiam order on the order to show cause (Gross, Ciklin, and Forst, JJ.), the court "impose[d] the sanction of referring counsel to the Florida Bar," citing Florida Rule of Judicial Administration 2.515(d)(2) and Florida Rule of Appellate Procedure 9.410(a), and referred the matter "for consideration of disciplinary proceedings" under Rule Regulating The Florida Bar 3-7.18(a)(2). The court held that the wrong-draft explanation "does not excuse the failure to verify the accuracy of all citations in his filing." It also examined the revised petition counsel said he intended to file and found that it too failed to disclose clearly established contrary law on jurisdiction, citing Rule 4-3.3(a)(3). The court concluded that, even if counsel was not trying to mislead, "the failure to discover the controlling law shows a violation of the duty of competence" under Rule 4-1.1. No monetary sanction was imposed. The petition had already been dismissed on June 30, 2026.

Why does JMOR Properties, LLC v. Artist Alley Townhomes, LLC matter for law firms using AI?

JMOR Properties is a Fourth District Bar referral in which counsel acknowledged the defective citations and described the AI workflow he said produced them. The petition asked the court to review an order vacating a clerk’s default by asserting that the court had “repeatedly entertained, and granted” such review; the court found it cited a non-existent case allegedly from the Fourth District and other cases that do not support the proposition. In response to the show-cause order, counsel described his process: AI software researches and drafts, and he then verifies every citation and revises. The court recounted that, according to counsel, he “allegedly did that in this case” but “while he was making final edits, he inadvertently worked from the wrong version and ended up filing the AI’s initial draft.”

The court accepted none of this as a defense. Citing the same court’s May 2026 Eclectic Synergy decision for the rule that “[a]n attorney is subject to sanctions for filings that contain fictitious authority or ‘cite actual cases for inaccurate legal propositions,’” it held that the wrong-draft explanation “does not excuse the failure to verify the accuracy of all citations in his filing,” citing Rule 2.515(d)(2)(D). It also quoted the Second District’s Russell v. Mells statement that the court is “compelled to refer that lawyer to the Bar” when imaginary authorities are cited as law.

The order’s more unusual step is its review of “the revised petition which counsel alleges he intended on filing.” That version, the court found, still failed to disclose the settled caselaw holding that certiorari does not lie to review an order vacating a default where no judgment was entered, a line of authority it traced to 1979 and listed at length. “Any competent research (using AI or otherwise) should have revealed the abundant caselaw directly addressing our lack of jurisdiction.” The court therefore grounded the referral in competence under Rule 4-1.1 as well as in the false citations. Firms documenting compliance may wish to consider that verification of AI output extends to checking what the output left out.

Implications for your firm

Operational steps a firm reading this case may wish to consider documenting. Strategic and rule-application calls belong to your firm's attorneys.

  • Document version control for AI-drafted filings. Counsel said he had corrected the AI draft but filed the uncorrected version; the court held that explanation did not excuse the failure to verify every citation in what was actually filed.
  • Verify that research surfaces adverse controlling authority, not just that cited cases exist. The court found that the revised petition which counsel alleges he intended on filing omitted settled contrary law, citing Rule 4-3.3(a)(3) and Rule 4-1.1.
  • Review jurisdictional research before filing an extraordinary writ petition. The court noted that 'Any competent research (using AI or otherwise) should have revealed' its settled lack of jurisdiction.
