Legal Work Highlights

Primal Vantage Company, Inc. v. O’Bryan, 677 S.W.3d 228 (Ky. 2023)(vacating $18.2 million jury verdict)

FBT’s appellate team, led by Griffin Terry Sumner, represented a manufacturer in the successful appeal of $18.2 million jury verdict. The case involved a plaintiff’s catastrophic injuries sustained in a fall from a hunting tree stand. Reversing and remanding for new trial, the Kentucky Supreme Court not only vacated a multi-million-dollar verdict, but also clarified several products liability issues that will guide manufacturers through the litigation process to defend their products. First, the Supreme Court emphasized a trial judge’s role as “evidentiary gatekeeper” to ensure that only admissible evidence is presented to a jury and rejected the trial court’s admission of 78 other tree stand incidents. Second, the opinion confirmed that a design defect claim requires proof of “an alternative, safer design that is practical under the relevant circumstances.” In so doing, the Supreme Court rejected various purportedly alternative designs proposed by the plaintiffs, finding that those options were either not safer or not feasible when this tree stand was manufactured.

Bell Helicopter Textron, Inc. v. Dobbs, 2019 WL 2484691 (Ky. Ct. App. 2019)(vacating $22 million jury verdict).

FBT’s appellate team, led by Griffin Terry Sumner, successfully appealed the $22 million jury verdict. The case involved a triple-fatality crash of a medical transport helicopter that had been manufactured by FBT’s client. The Court of Appeals of Kentucky vacated the jury verdict and remanded the case for a new trial with an opinion that emphasized appropriate evidentiary limitations at trial, especially in products liability cases. The Court of Appeals’ opinion held that the trial court had improperly excluded certain deposition testimony from a Bell employee about the cause of the crash that contradicted other portions of the same deposition presented by the plaintiffs. The opinion also held that the trial court had erroneously allowed the plaintiffs to present a chart of past “service difficulty reports” for a variety of Bell’s helicopters with  no proof of the substantial similarity required for other incidents evidence.

Mosley v. Arch Specialty Insurance Company, 626 S.W.3d 579, 582 (Ky. 2021)(affirming dismissal of bad faith claims and confirming a plaintiff’s “steep burden” of proof).

FBT’s appellate team, led by Griffin Terry Sumner, represented one of the insurers facing an appeal of the dismissal of bad faith claims after limited discovery. The Kentucky Supreme Court’s opinion emphasized noted a plaintiff’s “steep burden” of proof in third-party bad faith claims. The Supreme Court’s opinion firmly established that Kentucky law requires a plaintiff to establish that the insured’s liability is “‘beyond dispute.’” Thus, “when an insured’s liability is unclear, bad-faith claims fail as a matter of law because the insurer has a reasonable basis for challenging the claim.” Indeed, an insurer has a contractual duty to its insured to provide a defense in such circumstances. The Mosley Court emphasized that even in prior cases where there was “evidence that the insured might be liable,” if the plaintiff could not “‘eliminate[] the reasonable possibility’” that the jury could find for the defendant insured, “no bad faith claim could stand as a matter of law against the insurance company.”   Honing in on this point, Kentucky’s Supreme Court held that “[w]hen liability is clear or ‘beyond dispute,’ a claim must be paid . . . . But when liability is not clear or disputed, an insurer may pursue its defense and contested liability until its duty under KUCSPA is triggered.”

Jenkins v. Estate of Garmon by Garmon, 2023 WL 5312169 (Ky. App. 2023)(mot. dis. rev. pending)(affirming of dismissal of claims against a road construction company where jury verdict against co-defendant exceeded $32 million).

FBT’s appellate team, led by Griffin Terry Sumner, successfully represented a road construction company in the appeal of a summary judgment in favor of the client, where a jury later awarded $32 million in damages against co-defendants. The Court of Appeals of Kentucky affirmed judgment in favor of the client, while also affirming the $32 million jury verdict against co-defendants. [A motion for discretionary review is pending with the Kentucky Supreme Court.]

Eastern Kentucky University v. Ohio Valley Conference, 2023 WL 129286 (Ky. App. 2023) (rev. denied)(affirming denial of sovereign immunity).

FBT’s appellate team, led by Griffin Terry Sumner, successfully represented a large collegiate athletic conference in a former member institution’s appeal of the denial of sovereign immunity. The case involved the conference’s contractual claims arising from the institution’s exit from the conference.  state university’s sovereign immunity to contractual claims by a collegiate athletic conference).  The Court of Appeals affirmed the denial of sovereign immunity, and the Kentucky Supreme Court denied discretionary review.

Shepherd v. Perry, Case No. 2023- CA-0388 (Ky. App. 2023)(writ of mandamus challenging replacement of estate administrator denied).

FBT’s appellate team, led by Griffin Terry Sumner, represented three sons challenging their father’s purported last will and the role of the father’s sibling as executor of the estate and in creating the purported will.  After the trial court removed the father’s sibling as executor and appointed a neutral, third-party public administrator, FBT successfully opposed the former executor’s petition for writ of mandamus in the Court of Appeals of Kentucky. [Further appeal pending Kentucky Supreme Court.]

Isaacs v. Fireman’s Fund Insurance Company, 2022 WL 495980 (Ky. App. 2022)

FBT’s appellate team, led by Griffin Terry Sumner, successfully represented a target insurer in a high profile plaintiff’s appeal from the dismissal of bad faith claims against multiple insurers. The Court of Appeals of Kentucky affirmed the dismissal of the bad faith claims, expanding precedent to the first party contest and rejecting arguments that a lack of discovery should have precluded dismissal. The Kentucky Supreme Court denied a request for discretionary review.

Blakeley v. Consolidated Insurance Company, 2021 WL 1327172 (Ky. App. 2021)(affirming declaration of no coverage under liability policy).

FBT’s appellate team, led by Griffin Terry Sumner, successfully represented an insurer in a coverage dispute involving a farm liability policy. The case involved allegations of fraud and intentional misconduct against the insureds and, thus, the question of whether the insureds were entitled to a defense and/or indemnification under the policy because of a covered “occurrence.” The Court of Appeals clarified the application of both prongs of the fortuity test described in earlier precedent.
