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.

Featured Conversations... Key Takeaways from A.M. Best’s Webinar on the Misuse Defense in Product Liability Claims, Featuring Michael Salvati

Michael Salvati, shareholder in our Philadelphia office, was a panelist for the April A.M. Best webinar, “The Misuse Defense: Strategic Approaches to Defending Product Liability Claims for Insurers.” During the program, Michael and his fellow panelists offered practical, jurisdiction‑specific guidance on how misuse and failure‑to‑warn theories intersect in modern product liability litigation. Michael emphasized the unique challenges these claims present—particularly in states like Pennsylvania, where evidentiary rules diverge sharply from those applied in many other jurisdictions. Failure to Warn as the “Flip Side” of Misuse Salvati explained that failure‑to‑warn allegations often arise as a direct counter to a misuse defense. As he noted, “If our misuse defense is that the plaintiff didn't use a product properly or safely, then the failure to warn claim is that we didn't tell them how to use it properly.” He emphasized that these claims can stem from either the absence of warnings or criticisms of existing warnings, such as insufficient specificity or lack of clarity about risks. Pennsylvania’s Unique Evidentiary Landscape One of Salvati’s most notable points was the stark difference in how Pennsylvania treats evidence of compliance with industry standards. He highlighted that Pennsylvania is “one of the only states…where that evidence is not admissible” in strict liability cases. Manufacturers cannot rely on compliance with ANSI, UL, ISO, or even federal safety standards to defend the product against a strict liability claim—because the focus is solely on the product itself, not the manufacturer’s conduct. Salvati acknowledged the challenge this creates for defense counsel and clients who expect such compliance to carry weight. Understanding the Three Defect Theories Salvati also walked through the three primary defect theories recognized in many jurisdictions: - Design defect – a flaw in the product’s intended design - Manufacturing defect – a deviation affecting a specific unit - Failure to warn – inadequate instructions or warnings He noted that warnings claims are increasingly significant and sometimes stand alone when design or manufacturing theories are weak. As he put it, plaintiffs often default to warnings claims because “the default position seems to be, ‘If I got hurt, there must be something wrong.’” Warranties and State‑by‑State Variations Salvati addressed how breach‑of‑warranty claims fit into the broader framework, explaining that implied warranties—such as merchantability—often overlap with strict liability in Pennsylvania. He emphasized the importance of understanding local nuances, as warranty law and admissibility rules vary widely across states. Looking Ahead: The Growing Importance of Warnings In his closing remarks, Salvati stressed that warnings should never be treated as an afterthought in product liability defense. He observed that warnings‑only claims are becoming more common and urged manufacturers and insurers to continually evaluate the clarity and completeness of their instructions and warnings. His takeaway: “We should always be talking about what are the instructions that come with our products…to bolster a misuse defense.” Listen to the complete webinar here: https://www3.ambest.com/conferences/events/eventregister.aspx?event_id=WEB1074.

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.

Legal Update for Special Education Law: Recent Positive Outcomes From the Group

Hearing Officer Confirms District Acted Appropriately Under IDEA and Section 504 William J. McPartland (Scranton) obtained a finding in favor of our client, a school district, on all issues following a due process hearing. The parent had filed a due process complaint alleging that the school district had breached its child find duty under the IDEA and Section 504, that the school district had discriminated against the student on the basis of disability in violation of Section 504, and that the school district had denied a free and appropriate public education to the student both by developing inadequate IEPs and via an actionable procedural violation.  Specifically, the student had received a Section 504 evaluation in October 2023, after a number of behavioral infractions culminating in a fight in September 2023, was identified as having anxiety and a sleep disorder, and received appropriate Section 504 accommodations. The student had never previously demonstrated signs of a learning disability, and the parent denied the school district permission to evaluate the student for special education needs in November 2023, and January 2024. The parent granted the district permission to evaluate the student in October 2024, after a private psychologist diagnosed the student with Attention Deficit Hyperactivity Disorder, possible Oppositional Defiance Disorder, a learning disorder, and anxiety. The school district issued a special education evaluation report in December 2024, finding that the student had an emotional disturbance and other health impairment, and an IEP providing an itinerant level of emotional support, as well as instruction in academics and social skills, was issued in January 2025, and amended in February, March, and April 2025. The student withdrew from the school district in April 2025, to attend a cyber charter school. The hearing officer determined that the school district had not violated its child find duty to the student in violation of either the IDEA or Section 504 where the district developed a Section 504 plan for the student within a month and a half of the parent’s first request for a Section 504 evaluation and where the parent repeatedly denied consent to conduct an IDEA evaluation of the student. The hearing officer noted that the student’s sporadic record of behavioral infractions prior to September 2023, did not suggest that the student had a disability prior to the parent’s initial request for an evaluation. The hearing officer further determined that no evidence had been produced to suggest that the student was discriminated against on the basis of disability in violation of Section 504. Additionally, the hearing officer determined that the IEP offered to the student was substantively adequate and that, to the extent the social and emotional programming offered by the school district was not received by the student, this resulted from the parent’s refusal to accept the same. The hearing officer finally determined that the school district did not commit an actionable procedural violation by delaying development of an IEP for the student where the parent repeatedly denied consent to evaluate the student. Court Dismisses Three of Four Claims Against School District Christopher J. Conrad and Daniel P. McGannon (Harrisburg) achieved a significant early victory on behalf of a school district client in. The team successfully obtained dismissal of three of the four claims asserted in the plaintiff’s amended complaint. The former district superintendent brought multiple claims arising out of his alleged “forced resignation,” including age discrimination under the ADEA, a Section 1983 Equal Protection claim, a Pennsylvania Whistleblower claim, and breach of contract. On behalf of the district, the defense team moved to dismiss the complaint in part, arguing: The plaintiff failed to plead sufficient facts to support a prima facie case of age discrimination. The equal protection claim was barred because the ADEA provides the exclusive federal remedy for age-based employment claims. The breach of contract claim could not stand because the underlying employment agreement had expired prior to the alleged breach. The court agreed, dismissing the ADEA, equal protection, and breach of contract claims in their entirety. As a result, only a single claim under the Pennsylvania Whistleblower Law remains pending. This outcome substantially narrows the scope of the litigation and positions the client for a more efficient defense moving forward.
