The arbitration of claims can take several different forms in Pennsylvania, but can be generally categorized as either compulsory judicial arbitration. The arbitration system in Allegheny County provides for simple and concise pleadings and a trial of the issues enabling the parties to resolve claims.An agreement to arbitrate a controversy on a nonjudicial basis shall be conclusively presumed to be an agreement to arbitrate pursuant to Subchapter B. Cases must be filed in the Office of the Prothonotary. In the event a grievance cannot be resolved, some labor contracts allow for arbitration to settle the grievance. All Civil Trial Division matters including arbitration level cases are filed through the civil electronic filing system. The rules governing arbitration have recently changed in Pennsylvania. The older law, the UAA or Uniform Arbitration Act, was adopted in 1980. A court may stay arbitration proceedings on a showing that there is no agreement to arbitrate. 42 Pa. C. S. § 7302 (b).
