The Pennsylvania Supreme Court has declined to review a Superior Court ruling that said an insured is entitled to stacked uninsured/underinsured motorist benefits because his insurer failed to have him sign new stacking waivers when he added his most recent vehicles to his policy via endorsement.

In a nonprecedential opinion in Newhook v. Erie Insurance Exchange, a three-judge panel of the court unanimously upheld a decision by Monroe County Court of Common Pleas Judge David J. Williamson from last May. Plaintiff Kenneth Newhook had sued Erie seeking a declaratory judgment that he was entitled to the stacked coverage, which Williamson granted, citing the Superior Court cases of Pergolese v. Standard Fire Insurance and Bumbarger v. Peerless Indemnity Insurance for guidance.
