Settlement Agreements Upheld in Florida Workers’ Compensation Cases

We successfully argued that a settlement agreement, based upon a binding and enforceable agreement reached via email between the parties, is enforced. The claimant had given her attorney authority to settle, but subsequently changed her mind. Based upon case law, there was unequivocal authority to settle and it was too late for the claimant to negate the agreement previously reached. The judge of compensation claims agreed and upheld the settlement. In another matter, we filed a motion to enforce a settlement agreement reached by the parties at mediation, which the judge of compensation claims granted. Despite attending mediation, reaching an agreement and having a mediation report drafted, the claimant did not sign the agreement. He then terminated the services of his attorney and retained new counsel. At the hearing held before the judge, Linda called the claimant’s former attorney as a witness and also conducted a direct examination of the claimant. Ultimately, the judge found that the claimant had agreed to settle and changed his mind later. Therefore, the settlement agreement was enforced.

Judge doesn’t buy that chemical exposure was major contributing cause for claimant’s complaints.

We won a total controvert on a workers’ compensation exposure claim and successfully defended a denial. The claimant alleged exposure to a toxic airplane paint thinner at a plant in Kentucky in December of 2019. He was a subcontractor of the airplane manufacturer, but a Florida employee. The claimant complained of breathing issues and skin rashes. He sought treatment at an emergency room in Kentucky on the date of alleged exposure ,and again approximately 10 months later for skin rashes. However, the claimant was able to continue working without any wage loss the entire time. The employer/carrier denied and defended on the basis that the claimant could not prove causation by clear and convincing evidence pursuant to F.S. 440.02. The claimant obtained an IME, which opined that his breathing issues could be attributable to the alleged exposure, but that the rashes most likely were not. The claimant’s IME physician opined that the claimant needed to undergo additional testing to determine causation. The employer/carrier’s IME opined that the major contributing cause of the claimant’s rashes and breathing issues was not the alleged exposure. The Judge of Compensation Claims accepted the employer/carrier’s IME and held that the claimant failed to prove that a workplace chemical exposure was the major contributing cause of his complaints.

Viewpoint: Florida’s New Heat Exposure Law May Impact Workers’ Comp

September 13, 2024

Florida House Bill 433, which was signed by Governor DeSantis in April and went into effect on July 1, 2024, prohibits cities and counties from requiring employers to provide their workers with shade, water breaks and other protections from hot temperatures. The law’s sponsor, Tiffany Esposito, R-District 77, explained that the goal was to prevent counties from having differing regulations. However, there are currently no laws in Florida that require heat protection for outdoor workers.

Attorneys Behaving Badly: Sanctions, Attorney’s Fees and Costs in Florida Workers’ Compensation Claims

September 1, 2023

Key Points: Florida workers’ compensation law allows for sanctions. While Judges of Compensation Claims are generally hesitant to award sanctions, there are very limited circumstances where they will do so. The vast majority of the time, the Florida workers’ compensation bar is a model of professionalism. There are more than 100,000 attorneys in the state of Florida, but the workers’ compensation bar is still small enough that everyone gets to know each other after practicing for a few years. They ask about kids and families. They celebrate weddings and share vacation pictures on social media. They are empathetic and move a deposition if someone is sick. Attorneys on opposite sides are friendly when encountering one another at conferences, seminars, and Inns of Court meetings. And it’s because of this genuine congeniality that most cases move through the system without overly antagonistic litigation. But there are always a few outliers. Judges of Compensation Claims (JCC) occasionally have to struggle with how to handle repeat violators as Florida workers’ compensation law does not have a bad faith clause. So how does a JCC send a message with some teeth when an attorney is unprofessional, overly aggressive, unresponsive, or hostile? Case law from the last few years has given us some guidance on what the First District Court of Appeals has found to be within the jurisdiction of the JCCs. Florida workers’ compensation law allows for sanctions pursuant to DOAH Rule 60Q-6.125 by striking claims, petitions, defenses, and pleadings, or allowing for the imposition of costs or attorney’s fees. It also allows for other general sanctions that the JCC may deem appropriate. However, traditional F.S.57.105 sanctions that are available in civil cases are not applicable in administrative workers’ compensation claims, unless they are at an appellate level.  In Mary Hektner v. School Board of Brevard County, OJCC# 13-014654RLD, 1st DCA 1D18-3792, PCA date April 15, 2019, counsel for the claimant had scheduled and noticed the adjuster’s deposition multiple times. A motion for protective order was filed and the employer/carrier’s attorney alleged that the deposition was going forward only to harass, annoy, or embarrass his adjuster and that there were very limited contested issues. The docket indicates extensive litigation and multiple issues appealed to the First District Court of Appeals. Relating to this adjuster’s live deposition, the attorney for the employer/carrier traveled from Orlando to Pompano Beach, stayed overnight in a hotel, and spent extensive time preparing the adjuster for the deposition. Counsel for the employer/carrier emailed claimant’s counsel three times and called multiple times, attempting to confirm that the deposition was going forward. Claimant’s counsel neither responded to the emails nor returned the calls. On the date of the deposition, he failed to appear in person or participate by phone. After the deposition was set to begin, claimant’s counsel’s office advised that the deposition was canceled. The employer/carrier then filed a motion for sanctions. The JCC ultimately found the circumstances warranted sanctions against claimant’s counsel only, and not the claimant. Pursuant to Florida Rules of Civil Procedure 1.310, the JCC awarded $3,661.50 for the employer/carrier attorney’s fees and $362.39 for costs. The First District Court of Appeals affirmed the decision per curiam.  In a similar case, Carlos Santiago v. American Airlines, OJCC# 19-029788JIJ 1st DCA 1D20-2931 PCA date April 5, 2022, Premise, a health care provider, filed a motion for sanctions against a claimant’s attorney after the granting of a motion for protective order. The claimant’s attorney (the same attorney from the Hektner case mentioned previously) had filed a motion to compel better responses when asked to produce a contract between the defendant/employer and Premise. The employer/carrier objected on the basis of relevancy and trade secrets privilege, as it related to the workers’ compensation case. The JCC granted Premise’s motion for protective order, finding the contract was not reasonably calculated to lead to admissible evidence. The judge entered an order denying the claimant’s motion, and the claimant then filed a motion for rehearing. Premise responded by filing a motion for sanctions based upon F.S. 440.32(3), indicating that there was no good faith argument related to the modification of existing law. Additionally, Premise argued the purpose for the motion for rehearing was to harass or needlessly increase the cost of litigation. A motion for rehearing cannot re-litigate the same issue, unless there is some reversal of existing law. In this case, Premise incurred legal fees in excess of $100,000 defending this issue. The JCC found that claimant’s counsel filed the motion for rehearing for an improper purpose and that an appropriate sanction was to pay an attorney’s fee to Premise’s Health in the amount of $3,358. The district court affirmed the decision per curiam.  On the other hand, in an evidentiary order on motion for sanctions in the case of Wilmer Hernandez Perez v. Seacrest Services/Travelers Insurance, OJCC #20-016176TAH dated March 2, 2023, the JCC found that it did not have enough evidence to warrant sanctions after the claimant missed four different depositions. The claimant appeared for the hearing on the motion for sanctions and testified that he was unaware of one of the dates of the deposition. Additionally, a Florida provision pursuant to DOAH Rule 60Q-6.125 provides that the party shall be served, but not filed, within 21 days of service of the motion for sanctions. This gives the allegedly offending party the ability to correct the deficiency and avoid the actual filing of the motion for sanctions. In the present case, the employer/carrier did not serve the motion on the claimant 21 days before filing it. The JCC, therefore, denied the motion for sanctions, indicating it was not a violation of the rules and the motion for sanctions was deficient.  While Judges of Compensation Claims are generally hesitant to award sanctions, these cases show the (very limited) circumstances where they are pushed the edge to do so. The Florida workers’ compensation bar strives to maintain the collegial reputation that it has earned by avoiding the bad behavior outlined in the situations above and hoping that younger attorneys learn from these errors for the future.  *Heather is a shareholder in our Jacksonville, Florida, office.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

Delaware Superior Court Clarifies Pleading Standard for Legal Malpractice Claims

In the matter of Edelstein v. Kirschner, No. N25C-09-018 FJJ, 2026 Del. Super. LEXIS 45, at *1 (Super. Ct. Jan. 29, 2026), the plaintiff law firm sued its former client for unpaid legal fees in the amount of $4,399.35. The former client asserted a counterclaim alleging legal malpractice. More, specifically, the former client claimed that his lawyer committed malpractice be recommending that he settle an underlying lawsuit by entering into a stipulated judgment for an excessive amount with interest that was accruing at “an outlandish” interest rate. The law firm moved to dismiss the counterclaim on the basis that its former client had not alleged facts reflecting that he could prove the case within the case. That is, facts reflecting that his attorneys caused him to lose the underlying case. The Superior Court held that while a legal malpractice plaintiff in cases arising from underlying litigation must prove the case within the case to survive a summary judgment motion, he does not need to plead facts reflecting as much in order to survive a motion to dismiss. While this case addresses the pleading requirements of a legal malpractice case in Delaware, it also serves as reminder that chasing unpaid legal fees from a former client can often give rise to a legal malpractice counterclaim. Attorneys seeking to collect unpaid legal fees should ensure that the fees they seek are for a significant amount, which would be recoverable if a judgment is obtained. Otherwise, the effort could backfire.

Pennsylvania Supreme Court Takes Up the Gist of the Action Doctrine

The gist of the action doctrine has been a hot topic in legal malpractice cases in Pennsylvania over the last several years.  Beginning in 2014, the Pennsylvania courts applied the gist of the action doctrine to professional liability actions, following the Pennsylvania Supreme Court’s opinion in Bruno v. Erie Ins. Co., 106 A.3d 48 (Pa. 2014).  In Bruno, the court applied the gist of the action doctrine to a professional negligence claim, and found that a negligence claim was not barred simply because the parties were in a contractual relationship where the gist of the claim sounded in negligence. Thereafter, courts in Pennsylvania applied the gist of the action doctrine to breach of contract claims as well, finding that where the allegations sounded in negligence, a plaintiff could not recast a negligence claim as one for breach of contract. This was important because of the distinction between statutes of limitations: negligence claims must be brought within two (2) years, while breach of contract claims can be brought within four (4) years.  Then, last year, the Pennsylvania Superior Court held that the gist of the action doctrine does not apply to breach of contract claims as seen through two opinions. These opinions were Swatt v. Nottingham Village, 342 A.3d 23 (Pa. Super. 2025) and Poteat v. Asteak, et al., 350 A.3d 198 (Pa. Super. 2025). That is, the gist of the action doctrine can bar a negligence claim but it cannot bar a breach of contract claim.  This month, the Pennsylvania Supreme Court granted the petition for allowance of appeal in Poteat.  The Supreme Court phrased the issue for consideration as follows: Whether the Superior Court majority’s holding conflicts with this Court’s holding in Bruno v. Erie Insurance Co., 160 A.3d 48 (Pa. 2014), as well as Superior Court opinions that applied Bruno, and departs from almost 200 years of controlling precedent that distinguishes between causes of action in contract and tort based upon the nature of the duty that was allegedly breached? Attorneys on both sides of legal malpractice matters no doubt look forward to clarification on these issues from our Supreme Court.

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.
