42 Pa.C.S. § 7341: Common law arbitration.

The award of an arbitrator in a nonjudicial arbitration which is not subject to Subchapter A (relating to statutory arbitration), A.1 (relating to revised statutory arbitration) or a similar statute regulating nonjudicial arbitration proceedings is binding and may not be vacated or modified unless it is clearly shown that a party was denied a hearing or that fraud, misconduct, corruption or other irregularity caused the rendition of an unjust, inequitable or unconscionable award.
