Results
Defense Verdict Received in an Insurance Exclusionary Clause Dispute
We received a defense verdict after bench trial in an insurance exclusionary clause dispute. The plaintiff’s personal property in a storage unit was damaged when a municipal water main broke outside the storage facility. The claims representative offered the full policy limits before trial. However, the plaintiff sought recovery of the full claim amount for her damaged property. We argued that her recovery was specifically excluded by the water damage exclusion provision within her insurance policy. The judge agreed and concluded that the water main was part of a containment system for water and the exclusionary clause was applicable.
Achieved Dismissal of an Appeal of Our Defense Verdict
We won dismissal of the plaintiff’s appeal of a defense verdict. Our client issued a professional liability insurance policy to the plaintiffs. When the plaintiffs were sued for legal malpractice, they notified our client of the suit and asked them to provide counsel to defend the matter. However, the plaintiffs never agreed to counsel proposed by our client. The plaintiffs then proceeded to mediation in the legal malpractice action and settled the matter without notifying our client. As a result, our client denied the plaintiffs’ request for indemnification. The plaintiffs then brought suit against our client for breach of contract and bad faith, alleging they wrongly denied indemnification and failed to provide counsel. The matter went to jury trial from April 8–11, 2024, where we successfully defended our client as the jury returned a defense verdict. The plaintiffs filed post-trial motions and then appealed the decision to the Superior Court of Pennsylvania, arguing the trial court erred in allowing the jury to see a copy of the insurance contract during their deliberations. The Superior Court dismissed the appeal and found that the plaintiffs waived their argument by failing to cite relevant legal authority in their appellate brief. The Superior Court also stated in a footnote that, should the court have reached the issue on appeal, it would have found it meritless because the insurance contract was a central piece of evidence to which the plaintiffs did not object during trial.

Ohio Supreme Court Holds That a Binding Appraisal Award May Not Be Set Aside Absent Specific Evidence of Manifest Mistake or Fraud
July 27, 2026
On July 23, 2026, the Ohio Supreme Court issued a rare opinion on the binding effect of an appraisal award in a property insurance policy. The Court in One Church held: A binding appraisal award will not be set aside unless an error is so palpably wrong that it undermines the intent of the agreement, such as corruption or gross mistake, not a mere error of judgment—To plead a claim of mistake with particularity as required by Civ.R. 9(B), facts alleged in a complaint must constitute the elements of mistake—Allegation that additional, hidden damage was discovered after appraisal award failed to state a claim of mistake that could justify setting aside binding appraisal. The case arose out of a claim brought by One Church against its insurer, Brotherhood Mutual Insurance Company for roof damage from a storm. Pursuant to the terms of the insurance policy, the parties agreed to submit the matter to appraisal. The two appraisers inspected the building, and both appraisers agreed that the damages were $313,271.98. The insurer paid the agreed appraised amount. Thereafter, the insured submitted a claim for an additional $206,663.09 in damages. The insured argued that these additional damages were not discovered until after the repairs began, and that they should be permitted to submit an additional claim, even though there had already been a binding appraisal of damages. The insurer refused to pay the additional damages, and the insured sued for breach of contract and bad faith. In the trial court, the insurer moved to dismiss for failure to state a claim, arguing that the binding appraisal award barred any further claims. The insured took the position that additional hidden damages could not be discovered until after the repairs began, and therefore there was a mutual mistake. The trial court dismissed the case on the insurer’s motion, because there was no “evidence of fraud, misfeasance, or mistake”. The Court of Appeals agreed that appraisal awards are generally binding, but noted that an appraisal award can be set aside for fraud or manifest mistake. The Court of Appeals reversed and remanded the case to the trial court, finding that the insured had pled mistake with sufficient particularity. The insurer appealed to the Ohio Supreme Court. On appeal, the Ohio Supreme Court reversed the Court of Appeals, and reinstated the trial court decision dismissing the case for failure to state a claim upon which relief can be granted. The Supreme Court found that since the insured had already demanded appraisal, and the appraisal award was binding, “something more than error of judgement, such as corruption in the arbitrator, or gross mistake” must be pled with particularity, and proven for the insured to override the appraisal award. Since the complaint did not allege fraud or manifest mistake with sufficient particularity, something more than a mere error of judgment, the complaint was insufficient to state a claim. The complaint in this case did not challenge the appraisal award. It pled that additional damages were discovered that were not apparent when the appraisal was done. It did not specify “who discovered the damages, how they were discovered, where they were found, why they were previously hidden, or why they rise to the level of a manifest mistake that the “appraiser would have corrected...had it been called to his attention”. Id at ¶22 citing Lakewood Mfg. Co. v. Home Ins. Co. of New York, 422 F.2d 796, 798 (6th Cir. 1970). Cases deciding the effect of appraisal awards are unusual. The Ohio Supreme Court’s decision in One Church relies primarily on 19th century case law for its conclusion. This emphasizes the fact that there is minimal case law deciding the effect of binding appraisal clauses in property insurance policies, and makes this case all the more significant. A lengthy dissent was written by Justice Fisher, who would have affirmed the Court of Appeals decision reversing and remanding the case for a decision on the merits. Of course, the decision works both ways, and an insurer dissatisfied with a binding appraisal award will likewise be without further recourse absent evidence of corruption, fraud, misfeasance, or manifest mistake, which must be pled with particularity. To constitute manifest mistake, “the mistake must be of such character that the arbitrator or appraiser would have corrected it had it been called to his attention.” Lakewood Mfg. Co. v. Home Ins. Co. of New York, 422 F.2d 796, 798 (6th Cir. 1970). The majority opinion does not specifically identify what would have been sufficient to plead mistake with particularity, or if the insured could have amended the complaint to overcome the deficiencies. The dissent argues that this was not really a case alleging mistake, but rather a question of contract interpretation. The insured did not challenge the appraisal, but argued that the hidden damage was not part of the appraisal, and the appraisal only covered the known damages. However, this argument did not carry the day with the majority. *Thomas F. Glassman, a shareholder in Marshall Dennehey’s Cincinnati office, filed a brief in the Ohio Supreme Court on behalf of the Ohio Association of Civil Trial Attorneys, in support of the insurer’s position.
