Arbitration (n.) The first of these is the arbitration under the act of June 16, 1836, which provides that the parties to, any suit may consent to a rule of court for referring all matters of fact in controversy to referees, reserving all matters of law for the decision of the court, and the report of the referees shall have the effect of a special verdict, which is to be proceeded upon by the court as a special verdict, and either party may have a writ of error to the judgment entered thereupon

Arbitration (n.) Compulsory arbitrations are perhaps confined to Pennsylvania. Either party in a civil suit or action,, or his attorney, may enter at the prothonotary's office a rule of reference, wherein be shall declare his determination to have arbitrators chosen, on a day certain to be mentioned therein, not exceeding thirty days, for the trial of all matters in variance in the suit between the parties. A copy of this rule is served on the opposite party. On the day. appointed they meet at the prothonotary's, and endeavor to agree upon arbitrators; if they cannot, the prothonotary makes out a list on which are inscribed the names of a number of citizens, and the parties alternately strike each one of them from the list, beginning with the plaintiff, until there are but the number agreed upon or fixed by the prothonotary left, who are to be the arbitrators; a time of meeting is then agreed upon or appointed by the prothonotary, when the parties cannot agree, at which time the arbitrators, after being sworn or affirm and equitably to try all matters in variance submitted to them, proceed to bear and decide the case; their award is filed in the office of the prothonotary, and has the effect of a judgment, subject, however, to appeal, which may be entered at any time within twenty days after the filing of such award. Act of 16th June, 1836, Pamphl. p. 715.
Arbitration (n.) This is somewhat similar to the arbitrations of the Romans; there the praetor selected from a list Of citizens made for the purpose, one or more persons, who were authorized to decide all suits submitted to them, and which had been brought before him; the authority which the proctor gave them conferred on them a public character and their judgments were without appeal Toull.
