At any time within one year after the award is made any party to the arbitration may apply to the superior court for an order confirming the award, correcting or modifying the award for plain mistake, or vacating the award for fraud, corruption, or misconduct by the parties or by the arbitrators, or on the ground that the arbitrators have exceeded their powers. Where an award is vacated and the time within which the agreement required the award to be made has not expired, the court may in its discretion, direct a rehearing by the arbitrators or by new arbitrators appointed by the court.
