ARBITRATION (Lat. arbitrari, to examine or judge), a term derived from the nomenclature of Roman law, and applied to an arrangement for taking, and abiding by, the judgment of a selected person in some disputed matter, instead of carrying it to the established courts of justice. In disputes between states, arbitration has long played an important part (see [Arbitration, International]). The present article is restricted to arbitration under municipal law; but a separate article is also devoted to the use of arbitration in labour disputes (see [Arbitration and Conciliation]).

Roman Law.—Arrangements for avoiding the delay and expense of litigation, and referring a dispute to friends or neutral persons, are a natural practice, of which traces may be found in any state of society; but it is from Roman Law that we derive arbitration as a system which has found its way into the practice of European nations in general, and has even evaded the dislike of the English common lawyers to the civil law. The praetor, who had the arrangement of all trials or private suits and the formal appointment of judges for them, referred the great majority of such cases for decision to a judge who was styled usually judex but sometimes arbiter. The phrase judex arbiterve frequently occurs. The judex and the arbiter had the same functions, and apparently the only express basis for the distinction between the two words is that there might be several arbitri but never more than one judex in a cause. The term arbiter seems, however, to have been sometimes used when the referee had a certain degree of latitude, and was entitled to give weight to equitable considerations (Roby, Inst. Rom. Law, i. 318; Hunter, Roman Law (1897), p. 48; and see Cicero pro Rosc. Com. 4, ss. 10-13; Gaius, Inst. iv. s. 163). Apart from this system of compulsory reference by the praetor, Roman law recognized a voluntary reference (compromissum) to an arbiter or arbitrator by the parties themselves. The arbitrator ex compromisso sumptus had no coercive jurisdiction, and in order to make his award effective, the agreement of reference was confirmed by a stipulation and usually provided a penalty (poena, pecunia compromissa) in case of disobedience. The sum agreed on by way of penalty might be either specific or unliquidated, e.g. “whatever the matter may be worth” (Dig. iv., tit. 8, s. 28). The arbitrator ex compromisso sumptus, like the judicial arbiter, was expected to take account of equitable considerations in coming to a decision. If three arbitrators were appointed, a majority could decide; in case of two being appointed and not agreeing, the praetor would compel them to choose a third (Roby, ubi sup., i. 320, 321; Dig. iv., tit. 8, s. 17). As in English law, it was necessary that the award should cover all the points submitted (Dig. iv., tit. 8, s. 21).

Law of England.—The law of England as to arbitration is now practically summed up in the Arbitration Act of 1889. This statute is an express code as to proceedings in all arbitration, but “criminal proceedings by the crown” cannot be referred under it (ss. 13, 14). The statute subdivides its subject-matter into two headings. I. References by consent out of court; II. References under order of court.

(1) Here the first matter to be dealt with is the submission. A submission is defined as a written agreement (it need not be signed by both parties) to submit present or future differences to arbitration, whether a particular arbitrator is References by consent of the court. named in it or not. The capacity of a person to agree to arbitration, or to act as arbitrator, depends on the general law of contract. A submission by an infant is not void, but is voidable at his option (see [Infant]). A counsel has a general authority to deal with the conduct of an action, which includes authority to refer it to arbitration, but he has no authority to refer an action against the wishes of his client, or on terms different from those which his client has sanctioned; and if he does so, the reference may be set aside, although the limit put by the client on his counsel’s authority is not made known to the other side when the reference is agreed upon (Neale v. Gordon Lennox, 1902, A.C. 465). The committee of a lunatic, with the sanction of the judge in lunacy, may refer disputes to arbitration. As an arbitrator is chosen by the parties themselves the question of his eligibility is of comparatively minor importance; and where an arbitrator has been chosen by both parties, the courts are reluctant to set the appointment aside. This question has arisen chiefly in contracts, for works, which frequently contain a provision that the engineer shall be the arbitrator, in any dispute between the contractor and his own employer. The practical result is to make the engineer judge in his own cause. But the courts will not in such cases prevent the engineer from acting, where the contractor was aware of the facts when he signed the contract, and there is no reason to believe that the engineer will be unfair (Ives and Barker v. Willans, 1894, 2 Ch. 478). Even the fact that he has expressed an opinion on matters in dispute will not of itself disqualify him (Halliday v. Hamilton’s Trustees, 1903, 5 Fraser, 800). So, too, where a barrister was appointed arbitrator, the court refused to stop the arbitration on the mere ground that he was the client of a firm of solicitors, the conduct of one of whom was in question (Bright v. River Plate Construction Co., 1900, 2 Ch. 835).

Under the law prior to the act of 1889 (a) an agreement to refer disputes generally, without naming the arbitrators, was always irrevocable, and an action lay for the breach of it, although the court could not compel either of the parties to proceed under it; (b) an agreement to refer to a particular arbitrator was revocable, and if one of the parties revoked that particular arbitrator’s authority he could not be compelled to submit to it; (c) when, however, the parties had got their tribunal fixed, and were proceeding to carry out the agreement to refer, the act 9 and 10 Will. III. c. 15 provided that the submission might be made a rule of court, a provision which gave the court power to assist the parties in the trial of the case, and to enforce the award of the arbitrators; (d) the statute 3 and 4 Will. IV. c. 42 (s. 39) put an end to the power to revoke the authority of a particular arbitrator after the reference to him had been made a rule of court; and—a liability which existed also under the act of 9 and 10 Will. III. c. 15—any person revoking the appointment of an arbitrator after the submission had been made a rule of court might be attached. The Arbitration Act 1889 provides that a submission, unless a contrary intention is expressed in it, is irrevocable except by leave of the court or a judge, and is to have the same effect in all respects as if it had been made an order of court. The object of this enactment was to save the expense of making a submission a rule of court by treating it as having been so made, and it leaves the law in this position, that while the authority of an arbitrator, once appointed, is irrevocable, there is no power—any more than there was under the old law—to compel an unwilling party to proceed to a reference, except in cases specially provided for by sections 5 and 6 of the act of 1889. The former of these sections deals with the power of the court, the latter with the power of the parties to a reference, to appoint an arbitrator in certain circumstances. Section 5 provides that where a reference is to be to a single arbitrator, and all the parties do not concur in appointing one, or an appointed arbitrator refuses to act or becomes incapable of acting, or where the parties or two arbitrators fail, when necessary, to appoint an umpire or third arbitrator, or such umpire or arbitrator when appointed refuses to act, or becomes incapable of acting, and the default is not rectified after seven clear days’ notice, the court may supply the vacancy. Under section 6, where a reference is to two arbitrators, one to be appointed by each party, and either the appointed arbitrator refuses to act, or becomes incapable of acting, and the party appointing him fails, after seven clear days’ notice, to supply the vacancy, or such party fails, after similar notice, to make an original appointment, a binding appointment (subject to the power of the court to set it aside) may be made by the other party to the reference. The court may compel parties to carry out an arbitration, not only in the above cases by directly appointing an arbitrator, &c., or by allowing one appointed by a party to proceed alone with the reference, but also indirectly by staying any proceedings before the legal tribunals to determine matters which come within the scope of the arbitration. Where the agreement to refer stipulates that the submission of a dispute to arbitration shall be a condition precedent to the right to bring an action in regard to it, an action does not lie until the arbitration has been held and an award made, and it is usual in such cases not to apply for a stay of proceedings, but to plead the agreement as a bar to the action (Viney v. Bignold, 1887, 20 Q.B.D. 172). The court will refuse to stay proceedings where the subject-matter of the litigation falls outside the scope of the reference, or there is some serious objection to the fitness of the arbitrator, or some other good reason of the kind exists.

An arbitrator is not liable to be sued for want of skill or for negligence in conducting the arbitration (Pappa v. Rose, 1872, L.R. 7 C.P. 525). When a building contract provides that a certificate of the architect, showing the final balance due to the contractor, shall be conclusive evidence of the works having been duly completed, the architect occupies the position of an arbitrator, and enjoys the same immunity from liability for negligence in the discharge of his functions (Chambers v. Goldthorpe, 1901, 1 Q.B. 624). An arbitrator cannot be compelled to act unless he is a party to the submission.

An arbitrator (and the following observations apply mutatis mutandis to an umpire after he has entered on his duties) has power to administer oaths to, or take the affirmations of, the parties and their witnesses; and any person who wilfully and corruptly gives false evidence before him may be prosecuted and punished for perjury (Arbitration Act 1889, sched. i. and s. 22). At any stage in the reference he may, and shall if he be required by the court, state in the form of a special case for the opinion of the court any question of law arising in the arbitration. The arbitrator may also state his award in whole or in part as a special case (ib. s. 19), and may correct in an award any clerical mistake or error arising from an accidental slip or omission. The costs of the reference and the award—which, under sched. i. of the act, must be in writing, unless the submission otherwise provides—are in the arbitrator’s discretion, and he has a lien on the award and the submission for his fees, for which—if there is an express or implied promise to pay them—he can also sue (Crampton v. Ridley, 1887, 20 Q.B.D. 48). An arbitrator or umpire ought not, however, to state his award in such a way as to deprive the parties of their right to challenge the amount charged by him for his services; and accordingly where an umpire fixed for his award a lump sum as costs, including therein his own and the arbitrators’ fees, the award was remitted back to him to state how much he allotted to himself and how much to the arbitrators (in Re Gilbert v. Wright, 1904, 20 Times L.R. 164). But in the absence of evidence to show that the fees charged by arbitrators or umpire are extortionate, or unfair and unreasonable, the courts will not interfere with them (Llandrindod Wells Water Co. v. Hawksley, 1904, 20 Times L.R. 241).

If there is no express provision on the point in the submission, an award under the Arbitration Act 1889 must be made within three months after the arbitrator has entered on the reference, or been called upon to act by notice in writing from any party to the submission. The time may, however, be extended by the arbitrator or by the court. An umpire is required to make his award within one month after the original or extended time appointed for making the award of the arbitrators has expired, or any later day to which he may enlarge it. The court may by order remit an award to the arbitrators or umpire for reconsideration, in which case the reconsidered award must be made within three months after the date of the order.

An award must be intra vires: it must dispose of all the points referred; and it must be final, except as regards certain matters of valuation, &c. (see in Re Stringer and Riley Brothers, 1901, 1 K.B. 105). An award may, however, be set aside where the arbitrator has misconducted himself (an arbitrator may also be removed by the court on the ground of misconduct), or where it is ultra vires, or lacks any of the other requisites—above mentioned—of a valid award, or where the arbitrator has been wilfully deceived by one of the parties, or some such state of things exists. An award may, by leave of the court, be enforced in the same manner as a judgment or decree to the same effect. Under the Revenue Act 1906, s. 9, a uniform duty of ten shillings is payable on awards in England or Ireland, and on decreets arbitral in Scotland.
