Defense Verdict Secured in a Dental Malpractice Action

We received a defense verdict in a dental malpractice action before the Luzerne County Court of Common Pleas. The plaintiff had a history of issues with his third molars (wisdom teeth) beginning in 2012. In 2013, he was referred to have one of them extracted by a prior dentist. In October 2015, the plaintiff presented to our client for a broken tooth. During the exam, our client advised him that he needed to have all four of his third molars removed. He even suggested it needed to be done at the next visit. However, the plaintiff did not schedule any further appointments. On January 10, 2017, the plaintiff presented with an infected third molar on the lower right. Our client suggested extracting both third molars on the right, as all of his third molars were broken down and sources of infection, but the plaintiff would only allow extraction of the lower tooth. The dentist extracted the tooth, gave a prescription of amoxicillin, and administered two loading doses to get the antibiotic to therapeutic levels more quickly. He also told the plaintiff to call if the swelling in his face did not improve or if it got worse. Over the next four days, his swelling got worse every day, but he did not call the dentist. Finally, on January 14, 2017, his swelling had progressed into his neck, and he called our client, who saw him and immediately sent him to the emergency department. He was admitted to the hospital for 40 days, was intubated, underwent 11 procedures, including multiple incision and drainage procedures, placement of a PEG tube, and a tracheostomy. The plaintiff’s experts agreed that a patient has responsibility for his own care, and failing to have his teeth extracted, or calling the doctor when the situation got worse, contributed to his injury. Although contributory negligence was on the verdict slip, the jury never got to the question as they found our client was not negligent.

Successfully Defended a Claim for Failure to Diagnose Infectious Endocarditis After a Periodontal Procedure

We successfully defended a claim for failure to diagnose infectious endocarditis after a periodontal procedure. The plaintiff, who was 56 at the time, was diagnosed with streptococcal endocarditis after undergoing periodontal surgery with our client. As a result, he required an aortic valve replacement and claimed he had to sell his business as he could no longer work. It was asserted at trial that our client, the periodontist who performed the surgery, and the co-defendant dentist failed to recognize signs and symptoms of potential infectious endocarditis in post-op interactions with the plaintiff. The claim also alleged that had the plaintiff been diagnosed sooner, he would not have required open heart surgery and could have successfully been treated with antibiotics only. We argued that the appropriate standard of care was followed and that the plaintiff’s damages were unrelated to the care and treatment provided by their client.

Perlmutter Provides Predictability for Punitive Damages Claims in Florida

In a much anticipated decision, the Florida Supreme Court provided clarity for the standards of proof for punitive damages claims in Perlmutter v. Federal Insurance Company, SC2024-0058 (Fla. June 11, 2026). Litigants and trial judges must be mindful of the standards laid out by the Court. And, defense practitioners must be prepared to alter their strategies to defend against such claims. Perlmutter came to the Court from the Fourth District, based on conflict jurisdiction with decisions from the Second and Fifth District and on certification of a question of great public importance as to the standard of proof for punitive damages claims at the pleading stage. Fed. Ins. Co. v. Perlmutter, 376 So. 3d 24, 29 (Fla. 4th DCA 2023). In the underlying case, the Fourth District made two conclusions. First, it held that a “trial court must consider the evidentiary showing by all parties at the hearing on the motion to amend, that is, evidence ‘in the record’ and evidence ‘proffered by the claimant.’”  376 So. 3d at 33. Second, the Fourth held that it “interpreted section 768.72(1) and (2) to require the trial court to make a preliminary determination of whether a reasonable jury, viewing the totality of proffered evidence in the light most favorable to the movant, could find by clear and convincing evidence that punitive damages are warranted.  Id. at 34 (underscoring in the original). In making these conclusions, the court cautioned trial courts that the “preliminary determination” analysis did not entitle the trial court to decide whether the evidence is clear and convincing and noted that the trial court should not weigh evidence and should not determine witness credibility. Id. The Florida Supreme Court accepted jurisdiction and answered the certified question in the negative. It quashed the decision below and remanded the case for application of the following standards: The trial court should consider only the evidence identified or proffered by the claimant; it should not entertain an evidentiary counter-submission from the opponent. The trial court should consider whether a reasonable person could conclude based on the claimant’s evidence, that the defendant committed “intentional misconduct” or “gross negligence” as defined in section 768.72(2) or section 768.72(3). The trial court must review the request for punitive damages in the context of the underlying claims. The trial court should not apply the clear and convincing standard of proof in reviewing the sufficiency of the evidence at the pleading stage. The trial court does not act as a fact-finder; the trial court must not weigh the claimant’s evidence—it cannot decide the truth of the matter. The trial court must consider the record evidence and the proffered evidence in the light most favorable to the plaintiff, but the allegations in the proposed amended complaint are not themselves evidence. Perlmutter, SC2024-0058 at 13-15 (emphasis added). In explaining these standards, the Court interpreted the text of the statute and compared it to a related statute which governs punitive damages in the nursing home context. The nursing home statute expressly calls for evidentiary submissions by “the parties” and expressly tells the trial court to determine whether there is a reasonable basis to believe the claimant could satisfy the “clear and convincing evidence” standard at trial. Id. at 17-18 (comparing the text of section 768.72(1), Florida Statutes, with section 400.0237, Florida Statutes). Without that express language in section 768.72, the statute could not be applied in the same manner. With these standards specially delineated for the trial courts, the Court is “confident that its interpretation of section 768.72(1) will not frustrate the effectiveness of the statute in accomplishing the Legislature’s textually evident purposes.” Id.  at 22 (cleaned up). This remains to be seen. While Perlmutter provides predictability and clarity for trial courts when reviewing the evidentiary submissions in support of a punitive damages claim, the decision will not likely impact the numbers of punitive damages motions filed. Rather, these new parameters will change the way claims are defended, reminiscent of a time when rulings on punitive damages were only subject to certiorari review and appellate courts were limited in reviewing procedural errors. This decision will likely deflate the level-playing field that Florida Rule of Appellate Procedure 9.130(a)(3)(G) addressed by allowing appeals of orders granting and denying punitive damages amendments. Further, Perlmutter may have impliedly created a call to action for the Legislature to amend section 768.72(1) in the same manner it amended section 400.0237 to allow the courts to analyze “admissible evidence submitted by the parties” and determine at a hearing whether there is a reasonable basis to believe the claimant at trial would be able to demonstrate by “clear and convincing evidence” that the recovery of punitive damages is warranted. Until then, defendants must adjust their strategies. To adapt to these new standards, defense practitioners will need to tailor their strategy for defending punitive damages claims since they can no longer submit a counter-proffer or urge a court to apply the clear and convincing standard at the pleading phase. Instead, defendants will need to attack the deficiencies in the claimant’s pleadings and proffer. If the trial court fails to serve as a gatekeeper, and does not apply the above standards, then defendants can pursue an interlocutory appeal under Rule 9.130(a)(3)(G). If a nonfinal appeal is taken, then defendants should move to stay any intrusive financial discovery while the appellate court analyzes the issues on appeal. Finally, defendants should utilize Florida Rule of Civil Procedure 1.510 to serve as a screening device to allow the trial court to analyze all evidence and prevent nonmeritorious punitive damages claims from proceeding to a jury.

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.

Unanimous New Jersey Supreme Court Holds That Personal Emails of Public Employees and Officials are Subject to OPRA

In Rosetti v. Ramapo-Indian Hills Regional High School Board of Education, the New Jersey Supreme Court unanimously held that government-related emails, which are contained within personal email accounts, are government records under the Open Public Records Act (OPRA), and a log of those emails must be produced when requested. In reaching this decision, the court conducted an analysis of the OPRA and cited previous cases that held that emails do in fact fall within OPRA’s definition of a record and must be produced when requested pursuant to the Act. The court in Rosetti then had to answer the question as to whether public officials’ personal email accounts that are used for government purposes are subject to OPRA, and found that they are. Rosetti made an OPRA request to the Board of Education seeking email logs from Board members’ personal email accounts. The Board refused to produce the logs and indicated that it was not under any obligation to produce personal email account logs, only from government-related email accounts. The issue was whether a log had to be produced for Board members’ personal email accounts, which they used to conduct Board business. The Board argued that while it was possible to create a log for government-related email accounts through its IT Department, it was not possible to do so for personal email accounts. The court rejected this argument and ruled that Board members are required to search their personal email accounts and create a log of government-related emails housed in those accounts. Once completed, each Board member then must submit a certification detailing the searches that were conducted. The court went one step further with a suggestion to government employees and officials, stating, “[g]overnment agencies should strongly advise their employees, elected officials, and others engaged in government-related business to refrain from using their personal email accounts when conducting government-related business.”  Please do not hesitate to contact me with any questions regarding this case and others pertaining to the OPRA.

They have opposed each other repeatedly, exhibiting peerless professionalism and exceptional civility, while zealously litigating under the unremitting pressure of high-profile litigation and record-setting verdicts totaling more than $3.5 billion. They have also collaborated, outside of litigation, on many commissions, committees, and projects of importance to the Pennsylvania judiciary and legal community. Litigation Department of the Year – Appellate Law, Winner (previous winner, 2025 and 2024) 2025 was another standout year for the firm’s Appellate Advocacy & Post‑Trial Practice Group, led by John J. Hare, which was retained to challenge many of Pennsylvania’s “nuclear” verdicts—awards exceeding $10 million.

Pennsylvania Supreme Court Holds Self-Referral Prohibition Does Not Cover Prescriptions Written by Physicians with Ownership Interests in Dispensing Pharmacies

700 Pharmacy v. Bureau of Workers’ Compensation Fee Review Hearing Office (State Workers’ Insurance Fund); Nos. 97, 98, 99, 100, 101 MAP 2024; decided June 16, 2026; by Justice Mundy.   In this case, Drs. Miteswar Purewal and Shailen Jalali, treating physicians for workers’ compensation claimants, wrote prescriptions for various medications that were filled by 700 Pharmacy. The worker’s compensation insurer refused to pay for the prescriptions on the basis that they were illegal self-referrals under the Act. 700 Pharmacy subsequently filed fee review applications with The Bureau of Workers’ Compensation Medical Fee Review Office. At a fee review hearing, both physicians stipulated they had a financial interest in the pharmacy.  The physicians argued that the Anti-Referral Provision of the Act does not bar self-referrals on prescription drugs and pharmaceutical services, since the provision does not specifically identify prescription drugs. The Fee Review Hearing Officer rejected this argument and found that prescriptions for medications are prohibited under the “goods or services” language included in the provision. 700 Pharmacy appealed to the Commonwealth Court, and the court affirmed, agreeing with the Hearing Officer’s interpretation of “goods and services” as encompassing prescriptions. 700 Pharmacy appealed to the Supreme Court.  The Supreme Court reversed the decisions of the Hearing Officer and the Commonwealth Court, holding that the term “goods and services” in the Anti-Referral Provision of the Act did not include prescriptions. According to the Court, “goods and services” was not a catch-all, but simply explanatory as to the eight enumerated categories in the provision. The provision (Section 306(f.1)(3)(iii)) reads, in pertinent part: Notwithstanding any other provision of law, it is unlawful for a provider to refer a person for laboratory, physical therapy, rehabilitation, chiropractic, radiation oncology, psychometric, home infusion therapy  or diagnostic imaging, goods or services pursuant to this section if the provider has a financial interest with the person or in the entity that receives the referral. The Court said that if the General Assembly wanted to specifically include prescription drugs and pharmaceutical services in the Anti-Referral Provision, they would have done so. They pointed out that prescription drugs and pharmaceutical services were included by the legislature in Section 306 (f.1)(3)(vi) of the Act as to reimbursement, and claimed that their omission from the Anti-Referral Provision supports the conclusion that those services are not included in the Anti-Referral Provision’s self-referral prohibition.

Summary Judgment Secured, Preserving $750,000 in Coverage for Insured in Major Trucking Liability Dispute

Ray Freudiger and Michael A. Roberts (both of Cincinnati) successfully obtained summary judgment on behalf of their client in a coverage dispute arising from a May 19, 2022, motor vehicle accident. A permissive driver operated a box truck for an interstate trucking company and caused severe injuries to two tort victims. Prior to the accident, the insured had procured a commercial auto policy for the trucking company with stated limits of $1,000,000. Following the accident, the insurer initiated a declaratory judgment action asserting that only reduced bodily injury limits of $25,000/$50,000 applied and later counterclaimed, alleging it would not have insured the driver had he been properly submitted for approval under the policy. After extensive discovery, briefing, and oral argument, the court rejected the insurer’s attempt to shift responsibility for the $750,000 in coverage it was legally required to provide for permissive drivers under Ohio law, granting summary judgment in favor of the insured and preserving $750,000 in liability exposure.
