    • 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.

Sixth Circuit Recognizes Heckler’s Veto Theory in Limited Public Forum

July 21, 2026

The Sixth Circuit reversed the Southern District of Ohio and ordered the district court to grant a preliminary injunction finding a strong likelihood of success on the merits of the plaintiff’s free speech claim related to an attempted public comment at a school board meeting. The plaintiff began to offer public comment by reading a written statement at a school board meeting when the board president cut off the microphone and put the meeting into recess. The board’s reaction followed a comment that the school district was failing and that the superintendent was a coward for not addressing critical race theory in the school curriculum. Per board policy, the speakers were allocated five minutes to make a statement. The plaintiff began her statement citing her various public roles in the region, then began to voice her disapproval of the board’s reluctance to audit the school curriculum against critical race theory. At 28 seconds into her speech, the plaintiff stated that she “recently heard about the failing Xenia Board of Education and the cowardice (sic) superintendent who cannot perform adequately in his role…”  The board president interrupted the plaintiff, shouting over her and threatening to cut the mic. The plaintiff continued to calmly read her prepared statement. The crowd began to loudly boo the plaintiff after the board’s threat. Board President Grech then moved the meeting into a recess. The plaintiff continued to speak over the booing crowd. A few seconds later, Board President Grech took the microphone away from the plaintiff but she continued speaking loudly without a mic as the board left the room. Although others were allowed to speak after the meeting resumed, the plaintiff was not permitted to complete her five minutes of public comment.  The plaintiff filed a 42 U.S.C. § 1983 action asserting a First Amendment claim under a “heckler’s veto” theory and sought a preliminary injunction to enjoin the board from enforcing its policy against her speech at future meetings. Board policy provided for five minutes of individual public comment but allowed the presiding officer to interrupt, warn, or terminate speech when the comments are repetitive, obscene, or constitute a true threat. The policy also allowed the presiding officer to request that an individual stop speaking or leave the meeting when the speaker is disruptive to the meeting, and should that fail, call for a recess or order the disorderly person removed. The board alleged that they halted the plaintiff’s speech because she was venturing down the path of name-calling, she was directly addressing the superintendent as opposed to the entire board, and that her conduct incited the crowd. In a hearing before the district court, Board President Grech agreed that she stopped the plaintiff from speaking because she was spreading baseless accusations and name calling. Notably, the board also chided another speaker for speaking just to the superintendent and not to the entire board, but did not take further action. That speaker spoke in favor of the superintendent. The plaintiff testified that despite her desire to speak again she felt threatened and a “little frightened” about speaking at a Xenia Board meeting without court intervention. Although the district court found that some of the plaintiff’s speech was protected, it found that the phrase “cowardice (sic) superintendent” was an unprotected ad hominem attack. The district court did not reach the question of whether the board’s regulation of the plaintiff’s speech was reasonable, finding that it was a fact question that could not be resolved at the hearing. The district court denied the injunction because the record at times favored each side of the dispute and therefore there was no clear indication that the plaintiff would succeed on the merits of the claim. Reversing the district court, the Sixth Circuit found that descriptors such as “failing” and “cowardice” are protected by the First Amendment, even in a limited public forum. The Circuit court stated that even if the plaintiff’s speech was offensive, the First Amendment protects that speech because anything less would allow the government to ban the expression of unpopular views. Regardless of the forum or the risk of offending some, viewpoint discrimination is impermissible. The court continued to state that it has never held that an ad hominem attack is per se unprotected speech, but further, that plaintiff’s speech was not an ad hominem attack (a personal dig or affront, or the criticism of an adversary’s character as opposed to the substance of the adversary’s arguments). As to the heckler’s veto arguments, for the first time the Circuit applied the Heckler’s Veto theory to a limited public forum and held that the board’s conduct amounted to a heckler’s veto. The First Amendment does not permit the government to curtail speech by succumbing to the crowd’s reaction to it. Removing a speaker due to crowd hostility will “seldom, if ever, constitute the least restrictive means available to serve a legitimate government purpose.” The court noted that in this case, not only did the board sanction the heckler’s veto, but in fact gave rise to it by threatening to turn off the microphone which only riled up the audience. Finally, the court also found that the equitable factors of a preliminary injunction – the likelihood to suffer irreparable harm – was satisfied with the possible curtailment of future speech. The court did not offer much analysis on this, but seems to imply that simply saying that there is a future intention to speak and that one is a “little frightened” to do so is enough. However, it seems most likely that the Court found the board’s action so distasteful that it did not put much analysis into this element and accepted the Plaintiff’s assertions without question. Aside from the ruling on speech protections – the court offers an interesting rebuke of the district court’s determination that the reasonableness of the board’s reaction was a question of fact, holding:  “A factual finding is clearly erroneous when the reviewing court is left with the definite and firm conviction that a mistake has been committed.  Here, the district court failed to make definitive credibility determinations, or probe into Grech’s testimony. Instead the district court framed the facts in the light most favorable to each side, and then determined it was too close to call. But courts have to make these calls, even the tough ones. The correct call here is that defendants provided no legitimate reason to regulate Boddy’s speech because Boddy shared views critical of the Board and Lofton.” There are a range of citable moments in this opinion, including Judge Bush’s own soapbox speech on the importance of protecting speech in the current political times in the concurrence!

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.

Commonwealth Court Reaffirms the Constitutionality of Act 111's IRE Provisions

In this case, the claimant sustained a work injury of January 6, 1994, which was acknowledged by Notice of Compensation Payable (NCP). After the claimant’s receipt of 104 weeks of temporary total disability benefits, the employer filed a Request for an Impairment Rating Examination (IRE). The IRE was performed in May 2023 and the IRE physician found that the claimant had a 5% whole person impairment, under the AMA Guides. The employer filed a Petition based on the IRE results, and the Petition was granted by the WCJ. During litigation, the claimant argued that the IRE provisions of Act 111 (Section 306(a.3) of the Act) were not applicable to her injury, since it predated June 24, 1996, the date Act 57 went into effect, and that the IRE provisions were unconstitutional. The Workers’ Compensation Judge (WCJ)) granted the Petition and the Board affirmed. On appeal to the Commonwealth Court, the claimant argued that Act 111 violated the nondelegation doctrine and that its retroactive application to the claimant’s injury was unconstitutional. The court rejected the arguments on the basis that they had already found the same arguments without merit in multiple, prior cases. The court also addressed an argument made by the claimant that Act 111 was procedurally defective under the Pennsylvania Constitution because it was only considered on two days in each House after having undergone amendments and reassignments. The court noted that the Pennsylvania Constitution requires every bill to be considered on three different days in each House. The claimant maintained that, according to the legislative history, the bill did not receive three separate days of consideration from each House when it was assigned a new bill number. The court pointed out, however, that the bill number, H.B. 1840 remained constant and was considered on three occasions by the House. Further, the court concluded that minor amendments to the bill were germane to its original subject, which was to modify the Act’s IRE process, in accordance with Protz II.

The Tolling Trap: Filing Alone Will Not Toll the Statute Without Good-Faith Service

The Eastern District of Pennsylvania recently reinforced a critical limitation on bad faith claims, holding that a timely filing alone will not preserve a cause of action absent a good-faith effort to serve the original process. The plaintiff had presented a claim for underinsured motorist benefits to his auto insurer. The insurer evaluated the claim and determined that the plaintiff’s accident-related damages did not exceed the bodily injury liability insurance limits of the at-fault driver and denied his claim. Among other claims, the plaintiff sought to present a claim for insurance bad faith under 42 Pa. C.S.A. § 8371, to which a two year statute of limitation applies. He first filed a praecipe for writ of summons before the expiration of the statute of limitation. However, the plaintiff did not attempt to serve the praecipe or writ until after the statute of limitations had expired. Additionally, the service failed as the plaintiff had mailed the original process to an incorrect address. Despite receipt of the Postal Service’s failure to deliver the original process, the plaintiff did not attempt to re-serve the writ. Two months later, the plaintiff filed a complaint and then successfully served that complaint. The insurer sought to dismiss the plaintiff’s bad faith claim as time-barred by the statute of limitations. The district court agreed. Though the plaintiff had filed a praecipe for a writ of summons prior to the expiration of the statute of limitations, the statute is only tolled if there is a good faith effort to serve that original process. In this case, the court determined that the plaintiff had failed to perform a “good faith effort to serve the original process”. Additionally, though the filing and service of a complaint can serve as alternative original process when the lawsuit is commenced by the filing of a praecipe for a writ of summons, the plaintiff filed his complaint after the statute of limitations had expired. The plaintiff’s bad faith claim was therefore determined to be barred by the statute of limitations and dismissed by the court, with prejudice. A key takeaway for the defense is not to assume that the statute of limitations has been successfully tolled by a plaintiff merely because a praecipe for a writ of summons or complaint has been filed prior to the expiration of the statute. A filed complaint or writ is only part of the equation. The defense should carefully review the docket and filings to confirm that the plaintiff also performed the requisite good faith effort to serve that original process. A thorough review of the docket may reveal that the plaintiff failed to make the good-faith service efforts necessary to toll the statute of limitations.

Florida Supreme Court Rules Florida Statute §627.70152 Does not Apply Retroactively

In a decision that resolves years of appellate uncertainty and confirms that insurers and insureds alike can rely on the legal framework in place when a policy is issued, the Supreme Court of Florida last week found that Florida Statute §627.70152, which involves an insured’s requirement to provide an insurer with pre-suit notice before filing a suit, cannot be applied retroactively. In Universal Property & Casualty Insurance Company v. Hughes, the Court was presented with the issue of whether the statutory pre-suit notice requirement applied retroactively and whether it would apply to a breach of contract of an insurance policy that was issued before the statute went into effect. Before the Court was an appeal from a homeowner, Ms. Hughes, who sued her insurance carrier, Universal Property & Casualty Insurance Company (Universal) for breach of contract under an insurance policy that was in effect from April 24, 2019 through April 24, 2020. During the policy period, Ms. Hughes suffered a loss and, on May 29, 2019, made a claim for water damage. The carrier investigated the loss and issued payment; Ms. Hughes disputed the payment, finding the amount insufficient for repairs. On July 1, 2021, Florida Statute §627.70152 went into effect, which required insureds to provide notice of intent to initiate litigation against the carrier prior to filing a lawsuit; if an insured filed the lawsuit without complying with §627.70152, a court must dismiss the case without prejudice. On August 4, 2021, Ms. Hughes filed her lawsuit against Universal for breach of contract. Universal moved to dismiss based on her failure to comply with §627.70152. Ms. Hughes contended the notice requirement could not be applied retroactively. The trial court disagreed and dismissed the lawsuit without prejudice, and Ms. Hughes appealed. During the appeal, the Fourth District Court of Appeal, in Cole v. Universal Property & Casualty, 363 So. 3d 1089 (Fla. 4th DCA 2023), ruled that Florida Statute §627.70152 did apply retroactively to policies issued before the effective date of §627.70152. However, the Sixth District Court agreed with Ms. Hughes and overturned the trial court’s ruling, finding the statute could not retroactively apply to policies issued prior to the statute effective date. Thereafter, the other district courts weighed in, with the Third District Court agreeing with the Fourth District Court, and the First, Second and Fifth District Courts agreeing with the Sixth District Court. In resolving the conflict amongst the district courts, the Supreme Court advised “as a general rule, ‘the statute in effect at the time an insurance contract is executed governs substantive issues arising in connection with that contract.’ Hassen v. State Farm Mut. Auto. Ins. Co., 674 So. 2d 106, 108 (Fla. 1996). The Court applied the two-step test when deciding whether a statute has retroactive application: “First, the Court must ascertain whether the Legislature intended for the statute to apply retroactively. Second, if such an intent is clearly expressed, the Court must determine whether retroactive application would violate any constitutional principles.” Menendez v. Progressive Exp. Ins. Co., 35 So. 3d 873, 877 (Fla. 2010). In analyzing the Legislature’s intent, the Court must determine whether the Legislature has manifested a clear command for retroactivity in the statutory text.  In review of the statutory text, the Court found nothing in the language of the statute to indicate that the phrase “all suits” was serving another purpose of expanding its reach to suits based on policies that both predate and postdate the enactment of the statute. Buis v. Universal Prop. & Cas. Ins. Co., 394 So. 3d 738, 741 (Fla. 2d DCA 2024). Further, the Court noted the statute has an effective date, which has long been considered to be evidence against retroactive application of a statute. The Court concluded that, on its face, no provision of §627.70152 speaks to application of the statute to insurance policies issued before the statute’s effective date and therefore, the Legislature did not clearly command retroactivity of the statute to include insurance policies issued prior to the enactment of the statute. The Court briefly reviewed Universal’s argument that the presuit notice requirement was procedural, not substantive, and therefore should be applied retroactively; however, the Court agreed with the Sixth District Court’s finding that, in its entirety, §627.70152 transformed an insured’s ability to sue an insurance company under a property insurance policy and an insurer’s obligations to respond to and pay insurance claims, thus making the requirement a substantive change. The Court thereby upheld the decision of the Sixth District and disapproved the decision of the Fourth District in Cole.
