In this regard, the County observes that courts have frequently utilized equitable principles when interpreting provisions of the Workers’ Compensation Act. See Kiebler v. WCAB (Specialty Tire of America), 738 A.2d 510 (Pa. Cmwlth. 1999) (en banc) (<HOLDING>); Roadway Express Inc. v. WCAB (Alien), 152 Pa.
