In any of the following cases the court shall after notice and hearing make an order vacating the award, upon the application of any party to the arbitration:

(1) Where the award was procured by corruption, fraud or other undue means.

(2) Where there was evident partiality or corruption in the arbitrators or any of them.

(3) Where the arbitrators were guilty of misconduct, in refusing to postpone the hearing, upon sufficient cause shown, or in refusing to hear evidence, pertinent and material to the controversy; or of any other misbehavior, by which the rights of any party have been prejudiced.

(4) Where the arbitrators exceeded their powers, or so imperfectly executed them that a final and definite award upon the subject matter submitted was not made.

(5) If there was no valid submission or arbitration agreement and the proceeding was instituted without either serving a notice of intention to arbitrate, as provided in RCW 7.04.060, or without serving a motion to compel arbitration, as provided in RCW 7.04.040(1).

An award shall not be vacated upon any of the grounds set forth under subdivisions (1) to (4), inclusive, unless the court is satisfied that substantial rights of the parties were prejudiced thereby.

Where an award is vacated, the court may, in its discretion, direct a rehearing either before the same arbitrators or before new arbitrators to be chosen in the manner provided in the agreement for the selection of the original arbitrators and any provision limiting the time in which the arbitrators may make a decision shall be deemed applicable to the new arbitration and to commence from the date of the court’s order.
