Portrait of Jillian L. Dinehart

Jillian is a member of the firm’s Professional Liability Department where she focuses her practice across a broad spectrum of professional liability matters, including but not limited to, the defense of municipalities and their employees, non profit directors and officers, real estate professionals, insurance agents and brokers, and employers. She has practiced in both state and federal courts and has argued before the Sixth Circuit Court of Appeals.

Jillian has been defending municipalities and their employees since 2013 and she has continued this practice with Marshall Dennehey, now leading the Cleveland office’s professional liability practice.  Although varied, Jillian’s public-sector liability practice focuses on police practices, sovereign immunity issues as well as labor and employment claims. Her employment practice extends to private employers, defending claims before the Ohio Civil Rights Commission, the EEOC, Ohio and federal courts regarding discrimination, harassment and retaliation, including claims brought pursuant to Title VII, the ADA, ADEA, the FMLA, trade secret litigation, whistleblower actions, housing discrimination and related tort claims.   

In her real estate work, Jillian has a strong track record of obtaining favorable results for real estate agents, real estate brokers, title agents, and home inspectors in cases brought against them related to alleged negligence, misrepresentation, disclosure errors, and contract disputes.  Jillian also concentrates her practice on D&O liability defending condominium and homeowners associations, as well as their directors, officers, and property managers, in matters involving alleged breaches of fiduciary duty, declaration disputes, real property document issues, and FHA, HUD and Fair Housing claims.  Additionally, she routinely defends insurance agents and brokers and miscellaneous professionals in matters pertaining to negligence, errors and omissions.  Jillian also has lived experience in non-profit D&O liability as a volunteer president of the board to a local community development corporation.

Further, Jillian’s practice extends to privacy and data breach matters, where she helps clients manage cyber risk and navigate incident response, containment, and compliance obligations. She also has experience defending corporate and individual insureds in product liability, construction, premises liability, and personal injury claims. 

A native of New York’s Finger Lakes region, Jillian earned her Bachelor’s Degree in Political Science from SUNY Albany. She received her juris doctor from Case Western Reserve University School of Law, where she launched her litigation career as an award winning student in the Criminal Defense Clinic. Before joining the firm in 2017, she gained valuable public sector experience as a judicial staff attorney and assistant director of law—skills she continues to draw upon in her advocacy for political subdivision clients.

Outside the office, Jillian can often be found enjoying live music or exploring the Cleveland MetroParks with her husband and their dogs.

    • Jillian’s Motion to Dismiss was affirmed on appeal after the Ninth District Court of Appeals found that Plaintiff had sued a non sui juris entity by suing a county department in a personal injury suit.  The Plaintiff initially filed suit against the department, and later dismissed without prejudice to allow more time to develop Plaintiff’s medical records.  When he refiled his suit, he again named a county department as the defendant.  Jillian filed a Motion to Dismiss arguing that a county department does not have the capacity to be sued.  Plaintiff then filed a Motion to Amend the Complaint and named the county.  Jillian then filed a Motion to Dismiss the Amended Complaint arguing that the plaintiff was outside of the statute of limitations and that the change in defendant could not relate back to the originally filed suit.  Plaintiff’s argument that naming the department was merely a misnomer and that the Amended Complaint should relate back to the original filing failed and the trial court dismissed the case.  After oral argument, the appellate court affirmed the decision.
    • In 2023, Jillian went to trial in a motor-vehicle accident case in which she represented a driver that had died while the case was pending.  There was also a large, financially successful, corporate co-defendant represented by other counsel.  The plaintiff had sustained a broken arm in the accident that was surgically repaired.  Jillian’s client had admitted liability, so the case was solely to be heard on the value of the injury, and the liability of the corporate co-defendant.  Likely counting on the deep pockets of the co-defendant, the Plaintiff’s pre-suit demand was not rationally related to the injury or in the realm of similar verdicts in the region.  During the first day of trial, Jillian formed a clear rapport with the jury panel, often engaging in friendly banter with the potential jurors about their own experiences in car accidents, injuries similar to the plaintiff’s, and the social impact of surgical scars.  This rapport was in direct contrast to a very dry voir dire by plaintiff’s counsel and was bolstered by a similarly friendly voir dire by the co-defendant’s counsel.  The parties completed their opening statements and returned to court in the morning, at which time the plaintiff asked to engage in settlement discussions.  As a result of Jillian’s trial performance, the case settlement for $1.5 Million less than the plaintiff’s demand the day before trial.

Results

Successfully Defended a Suburban Mayor in a Defamation Case

We successfully defended an appeal of a trial court decision dismissing a defamation claim against a suburban mayor. The plaintiff, a former police officer, brought actions against a former city mayor and related defendants, asserting defamation, false light and related claims. The plaintiff alleged that statements made during a press conference disparaged him and violated a non-disparagement clause in his separation agreement. The court ruled the defamation and false light claims were correctly barred by the one-year statute of limitations under R.C. 2305.11(A) where the saving statute, R.C. 2305.19(A), permitted refiling in federal court, but did not toll limitations for subsequent state filings after the federal court dismissal. The appellate court also found the former mayor’s statements, regarding police leaders who allegedly retaliated against her, were deemed truthful and, thus, not defamatory or disparaging.   

Summary Judgment Won in Slip and Fall Case Involving a Large Supermarket Chain

We won summary judgment in Franklin County, Ohio, for a large supermarket chain in a slip-and-fall case. The plaintiff alleged he slipped and fell in the parking lot on ice that remained more than two days after the most recent snow fall and after the lot had been plowed and salted by a co-defendant. The plaintiff’s expert opined that no amount of remaining snow or ice is acceptable and that the standard of care according to the Ohio Building Code requires complete removal in order to maintain a “slip-resistant” surface. However, in Ohio, a premises owner is not liable for natural accumulations of snow and ice because persons are expected to appreciate the danger. The plaintiff’s expert did not opine as to what the defendants should have done, other than to completely remove the snow and ice. The court struck the plaintiff’s expert’s untested opinion as being unhelpful to a jury and found that the Ohio Building Code did not apply to the plaintiff’s pleadings without a claim for negligence per se. In disregarding the expert opinions, the court also found that the remaining snow and ice was “natural,” even though there had been attempted removal.

Aw Heck, As-Applied Challenges do not Implicate a Conviction

April 1, 2026

A new ruling from SCOTUS gives a lesson in Greek mythology, but more importantly makes it a near certainty that civil-rights plaintiffs will be able to run their malicious prosecution suit through summary judgment, despite a conviction. The oral argument led many to believe that the justices felt this was a complicated case, but in Olivier v. City of Brandon, a unanimous Court found that a suit that seeks prospective relief from arrest is not barred by the previous ruling in Heck v. Humphrey. Heck holds that a civil suit cannot invalidate a criminal conviction and is most often cited in cases arguing dismissal of a malicious prosecution claim because the plaintiff had been found guilty of the relevant charge. However, under Olivier, if the same plaintiff pleads prospective injunctive relief, the case may continue without an ad damnum request for damages. The result is an as-applied constitutional challenge of the law under which the plaintiff was convicted. There is no question that there is merit in reviewing the constitutionality of statutes and ordinances – but the as-applied challenge comes with significant expense and limited functional results. The Court even acknowledges that for Olivier to succeed in his suit for prospective relief, a court would find “something past should not have occurred” – that “something past” being a conviction in most cases. To come to this conclusion and avoid the implications of Heck, Justice Kagan drew a parallel to a citizen that seeks to enjoin enforcement of an ordinance that would prevent the plaintiff from exercising his free speech in the manner he desires – of course before the exercise actually occurs. There is no question that Heck does not apply in the case of a preliminary injunction, but Olivier presents an interesting glance into a criminal justice system that allows an accused to challenge the constitutionality during the criminal trial, get convicted, then challenge the constitutionality again in a civil suit. Practitioners should consider a request for prospective relief as an as-applied constitutional challenge that will likely need to be briefed at the summary judgment stage, therefore requiring discovery into the circumstances of the arrest.

Totality of the Circumstances: Tasing Okay in Immediate Passive Resistance

January 1, 2026

In a colorful opinion from the Sixth Circuit, the court found that it was not excessive force to tase the plaintiff when he refused to supply his hand for cuffing in the wake of more significant refusals to submit to the police officers’ authority. Feagin marks a return to the totality of the circumstances review, holding that there must be a comprehensive look at any relevant event that influences the use of force. The officers first encountered Mr. Feagin driving a Lincoln SUV, windows down, drinking liquor, smoking marijuana and driving down the middle of the street, causing the police vehicle to go into the ditch. There was a short pursuit before Mr. Feagin pulled over into a crowded supermarket parking lot, at which time the officers noticed the rear window appeared to be shot out. As the officers approached the vehicle, Mr. Feagin rolled up the windows. When an officer reached the driver’s side window, the SUV began to roll backwards. The officers banged on the windows, and the SUV stopped rolling. Mr. Feagin opened the driver’s door, and the officers grabbed his arm, causing him to limply lean out the door, at which time he began to resist and struggled to keep his body inside the driver’s compartment. During this struggle, bullets were falling from Mr. Feagin’s pockets. Once on the ground, the two officers tried to get Mr. Feagin cuffed, one officer attempt to grab his left arm, while the other had a partial hold on his torso. Mr. Feagin’s right arm remained free and flailing against the SUV. The officer holding Mr. Feagin’s torso tased him, allowing the officers to fully detain Mr. Feagin and place him in the rear of the police cruiser. Mr. Feagin alleged that the tase was excessive force, and the district court agreed, finding there was a question of fact, whether Mr. Feagin was actively or passively resisting at the time the taser was used. The Sixth Circuit reversed, holding that the entire encounter with Mr. Feagin should be considered, during which there were numerous times of active resistance. The Circuit Court also held that, even if the taser was utilized during the “twilight” between active and passive resistance, the doubt should be resolved in favor of the officer making split second decisions where the threat or degree of resistance is unclear. The court held: “We impose liability on individual officers only in the rare instance where an officer tases a suspect who posed no danger and was fully compliant with officer’s commands or had completely ceased resisting at the time of tasing.” A dissenting opinion (J. Clay) pressed for a more limited review of the case, finding that the argument was based in fact, as opposed to legal analysis. In assessing the Circuit Court’s duty, the majority opinion railed against the dissent to hold: "[T]he mere existence of ‘competing allegations on both sides’ does not stand in the way of us assessing whether legal arguments likewise exist. (***) We instead consider the facts in a light most favorable to the plaintiff. Any other approach risks eliminating our review altogether in this setting. After all, facts permeate every qualified immunity dispute. And qualified immunity exists to protect against a government official’s mistake of both fact and law. Those protections would be ‘effectively lost if’ an appeal were dismissed and a case ‘permitted to go to trial’ simply because a party highlighted factual disputes in the court of appeal. So rather than throwing up our hands whether the parties disagree over the facts or whenever the district court has assessed the record, we instead roll up our sleeves and train our attention on any remaining legal questions." (Internal citations omitted.) The Feagin opinion should be cited by every defense practitioner in a tasing case or in a case where it seems the fact questions should outweigh the legal analysis.

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.

What’s Hot in Workers’ Comp - News and Results*

RESULTS* Ben Durstein (Wilmington) obtained a favorable decision involving a claimant who fractured his patella in a work accident requiring two surgeries. The IAB rejected the claimant’s medical expert’s opinion that he sustained a 25% permanent impairment to the right lower extremity. Instead, the board accepted the opinion of the employer’s medical expert that the appropriate permanency was 13% utilizing the 6th Edition of the AMA Guides to the Evaluation of Permanent Impairment. Tony Natale III (King of Prussia) successfully had a claim petition alleging new injuries and periods of disability dismissed based on full recovery. The claimant was injured when his skid loader was struck by another loader in the process of baling hay. Original injuries were accepted and the claimant returned to work. Thereafter, the claimant abandoned work and filed a claim petition to assert new injuries and extended disability. Cross examination of the claimant’s medical expert stunningly revealed his failure to review claimant testimony, his lack of awareness of a social security disability decision detailing the existence of claimant’s alleged work-related conditions prior to the date of work injury, and his failure to understand that the claimant admitted to full recovery of injuries for which he was continuing to treat. Tony Natale III (King of Prussia) successfully obtained a defense verdict in a Medicare conditional payment lien third level appeal. The United States government alleged a Medicare conditional lien payment was due and owing in the upper six-figure range based on an auto accident and PIP policy for which the government conditionally became the primary carrier. The government argued that our client, the PIP carrier, was the primary payer and, under federal law, must reimburse the government for its conditional lien payment. At the third-level appeal hearing, the government’s position was refuted by the revelation that the date of injury tied to the medical bills associated with the lien was glaringly and chronologically prior to the insurer’s PIP policy date. The court held that based on this evidence and argument, the government could not meet its requirements to assert a lien against our client. A. Judd Woytek (King of Prussia) and John Abda (Scranton) successfully had a workers’ compensation claim petition granted for medical benefits only for a closed period with no wage loss awarded. The claimant alleged multiple injuries as the result of a very minor motor vehicle incident where a co-worker’s delivery van rolled down an incline of approximately six feet, and bumped into the rear of the claimant’s delivery van. He claimed he was thrown forward and suffered head and neck injuries, along with aggravating a pre-existing ankle injury. The claimant was also terminated following the accident for having a large hunting knife in his van, which was against the employer’s workplace violence policy. The judge granted the claim for a mild concussion and an ankle contusion, but terminated medical benefits as of the date of our IME’s. The judge found that no wage loss benefits were payable as the claimant was terminated for cause and work remained available to him. The judge found our medical experts to be more credible than the claimant’s, along with finding our four employer witnesses to all be credible. The trial team was assisted by paralegal Bonnie Zemek (King of Prussia). Eric Scott Thompson (Wilmington) was successful in a workers’ compensation matter in Delaware. On October 15, 2024, the claimant was injured while performing fire training in a multistory building when he tripped over a fire line, injuring his right knee. The claimant received regular and consistent treatment for the right knee through August 29, 2025, when he presented with left knee complaints for the first time. His treating orthopedist diagnosed a hamstring strain. The claimant was next seen October 15, 2025, with continued left knee complaints, and was referred to a total knee doctor within the practice. He was then diagnosed with a posterior root tear of the medial meniscus. Our expert testified that it was not plausible for a lateral hamstring strain to progress to a meniscal tear in two months. The claimant required a total knee replacement that was ultimately performed in February 2026. In the six months between the time of initial presentation with left knee complaints and the total knee replacement, conservative care consisted of a single injection. Our expert testified that posterior root media meniscal tears can respond to conservative care, and it was not known if it would with the claimant because it was not adequately explored. The Industrial Accident Board agreed with our expert and determined that the claimant failed to meet the burden of establishing more likely than not that the left knee complaints were caused by overloading/overuse as a result of the compensable injury to the right knee. They also agreed that the claimant was able to return to work in a sedentary capacity as opined by his physicians and our expert prior to the left total knee replacement and that there were employment opportunities available within his restrictions and capabilities as presented by the vocational expert. As a result, the claimant was no longer entitled to total disability benefits and will receive partial disability benefits for which he is limited to 300 weeks. Michele Punturi (Philadelphia) and Alana Staniszewski (Pittsburgh) had a termination petition granted in a Pennsylvania workers’ compensation case. The petition involved an echocardiography technologist with long-term employment at a local hospital who sustained a right shoulder injury resulting in surgery in January 2024. Following surgery, the claimant was diagnosed with a frozen shoulder and underwent additional surgery in June 2024, with a recommendation for a third surgery. The opinions of the defense medical expert, a Board-certified orthopedic surgeon, were found credible, persuasive, and competent based upon the extensive history he obtained from the claimant, analysis of the mechanism of injury, and review of records, along with comparison of MRIs from October 2023, February 11, 2024, and January 6, 2025, which failed to reveal any causal relationship other than a strain/sprain of the right shoulder. This evidence supported that the claimant had fully recovered, and was not in need of any ongoing medical treatment and/or restrictions. In particular, despite allegations of injuries beyond a sprain/strain, the defense medical expert identified that those allegations were not consistent with what was found at the time of surgery, and elements of the surgery were to treat a chronic and degenerative condition. Additionally there were no ongoing issues or problems with the subscapularis, which was intact, consistent with the follow-up MRI of February 11, 2024, and the claimant did not have evidence of a frozen shoulder. In fact, the MRIs and mechanism of injury, he opined, did not support any injury causing tendonitis or inflammatory conditions within the bicep tendon. Furthermore, multiple days of surveillance footage demonstrated the claimant’s normal use, with the ability to sweep and shovel snow, operate her vehicle, raise her arms above shoulder level, and use a broom – all without any observable difficulty, which challenged the claimant’s credibility of a disability and further established a lack of causation. As a result of this favorable decision, supersedeas fund reimbursement will be obtained for both wage loss and medical benefits through the supersedeas fund recovery process. *Prior Results Do Not Guarantee a Similar Outcome NEWS Heather Carbone (Jacksonville) was a panelist for a webinar hosted by The Workers’ Compensation Claims Professionals (WCCP) Association. As part of the “Meet the Experts” Series, the speakers addressed “Afterthoughts that Undermine a Successful Mediation,” highlighting the pitfalls and challenges of underprepared or unprepared mediation participants. The discussion included appropriate pre-mediation communications, setting of expectations, management of expectations, and working through the unexpected or unprepared. Attendees gained ideas about how and when to prepare, best practices, and the potential for non-parties (spouse, significant other, risk owners-insurers) to have differing perspectives or concerns than the actual employee and employer. On May 21-22, 2026, A. Judd Woytek, (King of Prussia) joined a panel at the CLM Alliance (Claims and Litigation Management Alliance) Work Comp Conference in Nashville to present "We See You: How Employee Engagement Enhances Work Comp Outcomes." Judd and his fellow panelists discussed the positive impact of employee engagement on claim outcomes, return-to-work timelines, and overall claim costs.
