Court Confirms UIM Claimants Must Qualify as an ‘Insured’ Under the Policy Insuring Their Employer’s Vehicles in Order to Stack Their Personal Auto UIM Policy

Erie Insurance Exchange v. Russo, 343 A.3d 291 (Pa. Super. Ct. Jul. 22, 2025)

January 1, 2026

by Christopher W. Woodward

While in the course and scope of his employment and while operating a vehicle owned by his employer, Russo was injured in a motor vehicle accident. He submitted a claim for and obtained underinsured motorist (UIM) benefits from the insurer of his employer’s vehicle.

Russo next submitted a claim for UIM benefits under his personal auto insurance policy, issued by Erie. Erie denied the claim based upon the regular use exclusion.

Litigation ensued, with the trial court ultimately finding in Erie’s favor as a result of the Pennsylvania Supreme Court’s decision in Rush v. Erie Ins. Exch., where the court found that the regular use exclusion remained valid and enforceable.

Russo appealed to the Superior Court, which upheld the trial court’s ultimate conclusion that Russo was owed no UIM coverage under his personal auto policy issued by Erie, albeit on different grounds.

The court first reiterated that Section 1738 of Pennsylvania’s Motor Vehicle Financial Responsibility Law (regarding the stacking of uninsured and UIM benefits) states: “[w]hen more than one vehicle is insured under one or more policies providing uninsured or underinsured motorist coverage, the stated limit for uninsured or underinsured coverage shall apply separately to each vehicle so insured. The limits of coverages available under this subchapter for an insured shall be the sum of the limits for each motor vehicle as to which the injured person is an insured.

Russo argued that he was an “insured” of the auto policy issued to his employer, which provided coverage for the vehicle he was operating at the time of the accident. Erie argued that “insured” is a term of art and is limited to only “class one insureds,” who are the named insureds, resident relatives of the named insured and, if the named insured is a corporation, officers of the corporation.

The court reiterated that a claimant must be an insured under both policies implicated in a stacking situation in order to effectuate inter-policy stacking of UM/UIM insurance.

The Superior Court ultimately held that Russo was not an insured under the policy issued to his employer and, therefore, was unable to stack his personal auto policy and no benefits were owed by Erie. In its conclusion, the court stated: “[s]imply receiving UIM coverage for injuries sustained as an occupant in a first priority vehicle does not make one an ‘insured’ under the vehicle’s policy who is then entitled to stack one’s personal auto policy UIM coverage.”

UIM stacking cases often involve claimants operating or occupying their employers’ vehicles. This case is a reminder to confirm that the claimant qualifies as an insured under the employer’s policy and as statutory defined by Section 1738 before stacking of their personal policies can apply. This reminder should also extend to claimants operating or occupying any non-owned motor vehicle.

Appellate Division Affirms Dismissal of Legal Malpractice Counterclaim Against Martin Law Firm

In Martin v. Loury, 2026 N.J. Super. Unpub. LEXIS 1617 (App. Div. July 15, 2026), Martin Law Firm represented Kirk Loury in an employment matter Mr. Loury filed against his former employer, Concord Equity Group Advisors LLC (“Concord”). The allegations included, among other things, that Loury was not fairly compensated for his employment with Concord. After a bench trial finding in Loury’s favor, the Appellate Division remanded this matter in February 2016 for a second trial. During the second trial, Concord CEO, Lee Argush, testified to lower compensation estimate than first trial. On remand, the second trial judge awarded Mr. Loury the same damages as the first judge, finding Mr. Argush not credible. After the findings during the second trial, Martin Law Firm filed an action against Mr. Loury to recover legal fees and costs of representing Mr. Loury in a second bench trial and Mr. Loury filed a counterclaim against Martin Law Firm for legal malpractice, alleging he should have received an even higher award in the second bench trial. In this allegation, Mr. Loury, through his expert, claimed that Martin Law Firm should have recalled Mr. Loury to the stand to rebut Mr. Argush’s testimony to allege an alternative theory of damages. Mr. Loury’s expert admitted that the second judge already rejected Mr. Argush's theory and accepted Loury's damages theory. The trial court barred Mr. Loury’s expert and dismissed Loury's counterclaim with prejudice before convening the collection trial, and the jury ruled in Martin Law Firm’s favor. Mr. Loury appealed the trial court's pretrial rulings barring his liability expert from testifying in support of his legal malpractice counterclaim, denying his motion for summary judgment on that counterclaim, and denying his motion to amend his counterclaim by adding attorney Joseph A. Martin as a codefendant. In affirming the trial court’s decision, the Appellate Division held that the trial court properly excluded Loury’s expert testimony in the counterclaim against Martin Law Firm because the expert could not explain how calling Loury as a rebuttal witness would have increased damages when the second judge already rejected Mr. Argush's testimony and accepted Loury's damages theory, making the expert’s causation opinion speculative. The Appellate Division also held that the trial court properly denied Mr. Loury's summary judgment motion on his malpractice counterclaim because reasonable minds could differ on whether Mr. Martin's alleged failures would have changed the second judge's damages award, given the judge already found Mr. Argush not credible, creating genuine factual disputes precluding summary judgment. Also, the Appellate Division held that the trial court properly denied Loury's May 2023 motion to add Joseph Martin individually because the statute of limitations expired in February 2022, six years after the 2016 appellate remand when Mr. Loury incurred new legal costs, and relation back did not apply because Mr. Loury knew Mr. Martin's identity throughout and strategically chose to sue only Martin Law Firm in his 2019 counterclaim.
