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.

New Jersey Appellate Division Affirms Exclusion of Legal Malpractice Expert as Impermissible Net Opinion

Jack Slimm and Jeremy Zacharias obtained a favorable decision on behalf of their client in a case centering on the admissibility of expert testimony in legal malpractice actions. In Martin v. Loury, the New Jersey Appellate Division affirmed the exclusion of a plaintiff's legal malpractice expert, holding that the expert's opinions on causation and damages were too speculative to support the malpractice claim. The legal malpractice action arose from an underlying employment dispute involving claims for damages stemming from the breach of an employment agreement. The plaintiff alleged that defense counsel committed malpractice during a second trial by failing to recall the plaintiff as a rebuttal witness after the employer's CEO testified. According to the plaintiff's expert, additional rebuttal testimony would have bolstered the plaintiff's damages claims and led to a more favorable result. Both the trial court and the Appellate Division rejected that theory. The courts found that the expert could not explain how the proposed rebuttal testimony would have altered the outcome of the underlying case or resulted in any additional recoverable damages. Notably, the trial judge in the underlying employment matter had already rejected the CEO's testimony as not credible and had accepted the damages analysis advanced by the plaintiff. The court had also determined that the amount of damages was not genuinely disputed. As a result, the expert's opinion that additional rebuttal testimony would have produced a better outcome was unsupported by the record and based on speculation rather than evidence. The Appellate Division agreed that neither the plaintiff nor the expert could identify any actual damages attributable to the alleged malpractice or demonstrate the required element of proximate causation. The court further upheld the trial court's application of New Jersey's net opinion doctrine, finding that the expert failed to provide the necessary "why and wherefore" supporting his conclusion that the attorney's conduct caused a compensable loss. Because the opinions rested on unquantified possibilities rather than demonstrable facts, they were inadmissible. Key Takeaway for Legal Malpractice Defendants For attorneys and firms defending legal malpractice claims, Martin v. Loury underscores the importance of closely scrutinizing an opponent's expert report on the critical elements of proximate causation and damages. The decision demonstrates that a malpractice claim cannot survive where an expert merely speculates that different litigation tactics might have produced a better result. Instead, the plaintiff must present admissible expert testimony grounded in the record that explains how the alleged attorney error probably changed the outcome of the underlying matter and resulted in measurable damages.

Supreme Court of Pennsylvania Holds That Public Policy Does Not Prevent Insurance Coverage for Sex Trafficking Claims

On July 21, 2026, the Supreme Court of Pennsylvania issued an opinion emphasizing the limited circumstances in which courts may invoke public policy to bar insurance coverage, holding in Samsung Fire & Marine Insurance Co., Ltd. (U.S. Branch) v. RI Settlement Trust that Pennsylvania public policy does not preclude coverage for claims alleging that insureds enabled or profited from human sex trafficking. The decision rejects a line of federal district court decisions predicting otherwise and reinforces that Pennsylvania courts will invoke the public policy doctrine only in the clearest of circumstances. RI Settlement is particularly significant because it arose on certified questions from the United States Court of Appeals for the Third Circuit, giving the Supreme Court the opportunity to resolve an issue on which federal courts had predicted Pennsylvania law differently. RI Settlement arose out of four separate civil complaints in which the underlying plaintiffs alleged that, as minors, they were the victims of human sex trafficking at various hotels in Philadelphia. The plaintiffs claimed that the hotel owners were negligent in failing to stop the sex trafficking from happening at their hotels. After the filing of the lawsuits, the hotel owners sought coverage under their Commercial General Liability policies. The insurers initially defended the hotels under Reservation of Rights letters, though the carriers later filed Declaratory Judgment actions seeking declarations that they did not owe a duty to defend or indemnify. In short, the insurers argued in the alternative that they did not owe any obligation to provide coverage based upon Pennsylvania public policy (because the claims violated the Human Trafficking Law – 18 Pa.C.S. § 3011) and the terms and conditions of the policy. On motions for judgment on the pleadings, the District Court found for the insurers on the basis of public policy: There is no duty to defend or indemnify against actions arising out of an insured's criminal conduct related to the sex trafficking of minors. The Court appreciates that it may make public policy the basis of a judicial decision only in “the clearest of cases.” See Minnesota Fire & Cas. Co. v. Greenfield, 589 A.2d 854, 868 (Pa. 2004) (quoting Hall v. Amica Mut. Ins. Co., 648 A.2d 755, 760 (Pa. 1994)). Yet, the Court strains to imagine a clearer case than the one presented here in which the facts alleged indicate that Policyholders engaged in criminal conduct in violation of Pennsylvania's Human Trafficking Law. The hotel owners appealed the matter to the Third Circuit, which petitioned the Supreme Court of Pennsylvania to grant review of two certified questions of law: (1) whether Pennsylvania law had an “overriding public policy” against sex trafficking, such that an insurer’s duty to defend and/or indemnify is abrogated when an insured is alleged to have enabled or profited from such trafficking; and (2) if yes, is that duty abrogated whenever the insured’s alleged conduct would constitute a violation of the Pennsylvania Human Trafficking statute. Importantly, the certified questions did not ask the Supreme Court to determine whether the policies afforded coverage under their terms. Rather, the court was asked only whether Pennsylvania public policy independently barred coverage. As a result, the court assumed for purposes of answering the certified questions that the insurers otherwise owed a duty to defend and addressed only the public policy issue, leaving all policy-based coverage defenses for further proceedings. Because the court concluded that the answer to the first certified question was “no”, it did not reach the second issue. In reaching its determination that Pennsylvania public policy does not prohibit insurance coverage for sex trafficking claims, the court limited the impact of its decision in Minnesota Fire & Cas. Co. v. Greenfield, 855 A. 2d 854, 855 (Pa. 2004), which the RI Settlement opinion emphasized as having been an “Opinion Announcing Judgment of the Court” – or a plurality opinion. In Greenfield, the insured homeowner was sued by the estate of his houseguest who overdosed from heroin that he sold to her. The matter wound its way to the Supreme Court, which determined that the insurer did not owe a duty to defend or indemnify based upon Pennsylvania public policy, which criminalized the sale and use of heroin as a Schedule I narcotic. In RI Settlement, the court “decline[d] the invitation” to extend the rationale of the three-justice plurality in Greenfield beyond cases involving Schedule I controlled substances. In so holding, the justices in RI Settlement refused to “divine an overriding public policy pronouncement by the General Assembly by virtue of its enactment of the Human Trafficking Law.” The opinion further states that it is not “within the purview of this Court to rank the magnitude of the public policy underlying the various crimes defined in the Crimes Code. It is sufficient for the work of the courts to know that the General Assembly has identified conduct it deems harmful and dangerous to the maintenance of an orderly society and criminalized it.” While the court declined to declare that Pennsylvania public policy prohibits coverage for sex trafficking claims, the opinion in RI Settlement expressly states that insurers are free to include appropriate exclusionary language for such causes of actions in their policies if they desire to do so. It will certainly be interesting to see whether the insurance industry accepts the court’s invitation, or perhaps whether the Pennsylvania legislature steps in to clarify that sex trafficking claims are indeed of the type or magnitude that they should not be covered by insurance. In any event, we will, of course, continue to monitor this and other insurance coverage issues that arise before courts in Pennsylvania, New Jersey and throughout our firm’s geographic footprint and around the country.

Court Allows Recklessness and Punitive Damages Claims to Proceed After Work‑Zone Crash

In a case where a defendant filed preliminary objections against allegations of recklessness and punitive damages, the Susquehanna County Court of Common Pleas denied these preliminary objections. This case stems from a motor vehicle accident, where the defendants car struck the plaintiffs car after the defendant allegedly fell asleep at the wheel, going at a high rate of speed, through a construction work zone. Defendant first objected to the general allegations throughout the plaintiff’s complaint pertaining to “reckless” conduct contending that there were insufficient factual allegations to support the claim of reckless conduct. Defendant next objected to the plaintiffs claim for punitive damages, as punitive damages may only be assessed against a motorist for falling asleep while driving if there is further evidence to prove driver was aware of their drowsiness and risk of falling asleep. Lastly, defendant objected to plaintiffs complaint, claiming it lacked specificity. The court here found that the plaintiff had included in the complaint specific allegations related to the defendant’s alleged recklessness, including allegations regarding speeding in a work zone, almost striking the flagger, falling asleep at the wheel, and striking the plaintiffs vehicle which was stopped. Additionally, the court noted that falling asleep does not come without warning. The court found that these allegations were sufficient to support an allegation of recklessness at the pleadings stage.
