In case of arbitration, the matter or matters at issue shall be referred to three arbitrators, one of the three to be selected by each of the parties to the dispute, when there are but two such parties, and the third by the two thus selected.  When there are more than two parties to the dispute, one arbitrator shall be named by each of the several parties, and the arbitrators thus named shall add to their number others of their own choice, the number thus added to be limited to the number which will suffice to give a deciding voice to the arbitrators thus added in case of a tie vote among the arbitrators chosen by the contending parties.  In case the arbitrators chosen by the contending parties cannot agree upon an additional arbitrator or arbitrators, the additional arbitrator or arbitrators shall be chosen by the Body of Delegates.

On the appeal of a party to the dispute the decision of the arbitrators may be set aside by a vote of three-fourths of the Delegates, in case the decision of the arbitrators was unanimous, or by a vote of two-thirds of the Delegates in case the decision of the arbitrators was not unanimous, but unless thus set aside shall be finally binding and conclusive.

When any decision of arbitrators shall have been thus set aside, the dispute shall again be submitted to arbitrators chosen as heretofore provided, none of whom shall, however, have previously acted as arbitrators in the dispute in question, and the decision of the arbitrators rendered in this second arbitration shall be finally binding and conclusive without right of appeal.

If for any reason it should prove impracticable to refer any matter in dispute to arbitration, the parties to the dispute shall apply to the Executive Council to take the matter under consideration for such mediatory action or recommendation as it may deem wise in the circumstances.  The Council shall immediately accept the reference and give notice to the other party or parties, and shall make the necessary arrangements for a full hearing, investigation, and consideration.  It shall ascertain all the facts involved in the dispute and shall make such recommendations as it may deem wise and practicable based on the merits of the controversy and calculated to secure a just and lasting settlement.  Other members of the League shall place at the disposal of the Executive Council any and all information that may be in their possession which in any way bears upon the facts or merits of the controversy; and the Executive Council shall do everything in its power by way of mediation or conciliation to bring about a peaceful settlement.  The decisions of the Executive Council shall be addressed to the disputants, and shall not have the force of a binding verdict.  Should the Executive Council fail to arrive at any conclusion, it shall be the privilege of the members of the Executive Council to publish their several conclusions or recommendations; and such publications shall not be regarded as an unfriendly act by either or any of the disputants.
