In Yonkers v. Donora Borough, 702 A.2d 618 (Pa. Cmwlth. 1997), the claimant, a police officer, sustained injuries in a work-related automobile accident entitling him to benefits under both the Workers' Compensation Act and the Heart and Lung Act. The borough employer filed a termination petition, which the WCJ granted after finding that the claimant had fully recovered from his injury. Thereafter, the borough terminated the claimant's Heart and Lung benefits for the reason that the WCJ's decision was conclusive on the issue of disability. The Court affirmed, holding that a final decision of a WCJ has collateral estoppel effect in a subsequent Heart and Lung Act proceeding.
