FIRST HORIZON BANK, ETC., ET AL.

v.

STEVEN HAYWORTH

SCALES, C.J. Petitioner First Horizon Bank, as successor in interest to Gibraltar Private Bank & Trust Company after merger (“the Bank”), the defendant below, petitions this Court to issue a writ of prohibition that precludes the trial court from exercising jurisdiction over the third amended complaint filed by the plaintiff below, respondent Steven Hayworth. Because the trial court was divested of case jurisdiction in the lower proceeding after the court's entry of a July 31, 2025 final summary judgment that fully adjudicated Hayworth's operative second amended complaint, we grant the petition.

I. RELEVANT FACTS AND PROCEDURAL HISTORY

Hayworth's operative second amended complaint alleged employment-related claims against the Bank that sounded in tort and contract.¹ Hayworth's claims stemmed from the circumstances surrounding his May 2012 resignation as president and chief executive officer of the Bank and the Bank's alleged failure to honor the severance provisions of his employment agreement.

On October 25, 2018, the trial court entered a non-final order dismissing, as premature, Hayworth's contract claims against the Bank.

Years passed without Hayworth obtaining the requisite federal regulatory agency approval that would permit him to amend his pleading to reallege his contract claims. Citing that failure, the Bank moved for summary judgment on Hayworth's surviving tort claims. Following a two-day hearing, the trial court entered a July 31, 2025 order that adjudicated Hayworth's tort claims in the Bank's favor and, noting Hayworth's continued inability to refile his contract claims, entered final summary judgment against Hayworth. This final summary judgment reserved jurisdiction only to consider any timely filed motions for attorney's fees and/or costs.

Hayworth did not file a Florida Rule of Civil Procedure 1.530 motion for rehearing. Nor did Hayworth appeal the July 31, 2025 final summary judgment. Instead, on August 20, 2025, Hayworth filed below an August 19, 2025 letter from the Federal Deposit Insurance Corporation that Hayworth

The Bank then moved to strike Hayworth's third amended complaint, claiming that the trial court lacked case jurisdiction to hear matters beyond the attorney's fees and costs issues expressly reserved in the July 31, 2025 final summary judgment. Following a November 13, 2025 hearing, the trial court entered an order denying the Bank's motion to strike Hayworth's third amended complaint "for the reasons stated on the record.” The hearing transcript reflects that the trial court refused to strike Hayworth's third amended complaint “as a matter of fundamental fairness” because Hayworth had purportedly obtained the requisite federal regulatory agency approval contemplated by the Dismissal Order. The Bank now petitions this Court to issue a writ of prohibition precluding the trial court from conducting further proceedings on Hayworth's third amended complaint.

II. ANALYSIS

"The writ of prohibition is an extraordinary remedy that 'may only be granted when it is shown that a lower court is without jurisdiction or attempting to act in excess of jurisdiction.” Sentry Pub. Adjusting, LLC v. Captiva Lakes Condo. Ass’n, 389 So. 3d 561, 565 (Fla. 3d DCA 2023) (quoting English v. McCray, 348 So. 2d 293, 296 (Fla. 1977)). Here, as below, the Bank claims that the trial court acted in excess of its case jurisdiction³ by permitting Hayworth to file the third amended complaint after the court entered the July 31, 2025 final summary judgment from which Hayworth failed to seek rehearing or appeal. We agree.

Hayworth argues that, because the Dismissal Order expressly contemplated the filing of an amended complaint once he obtained federal regulatory approval, the trial court retained case jurisdiction to adjudicate his third amended complaint, notwithstanding the entry of the July 31, 2025 final summary judgment. But the Dismissal Order like all orders that grant motions to dismiss with leave to amend was a non-final, non-appealable order. "It is well-settled that interlocutory orders merge into the final judgment." Citizens Prop. Ins. Corp. v. All Ins. Restoration Servs., Inc., 365 So. 3d 434, 435 (Fla. 3d DCA 2023). This merger “extinighuish[es] the trial court's authority to enter further orders regarding the interlocutory matters.”
