Section 12-1512 - Opposition to an awardA. Upon filing of a pleading in opposition to an award, and upon an adequate showing in support thereof, the court shall decline to confirm and award and enter judgment thereon where:1. The award was procured by corruption, fraud or other undue means;2. There was evident partiality by an arbitrator appointed as a neutral or corruption in any of the arbitrators or misconduct prejudicing the rights of any party;3. The arbitrators exceeded their powers;4. The arbitrators refused to postpone the hearing upon sufficient cause being shown therefor or refused to hear evidence material to the controversy or otherwise so conducted the hearing, contrary to the provisions of section 12-1505, as to prejudice substantially the rights of a party; or5. There was no arbitration agreement and the issue was not adversely determined in proceedings under section 12-1502 and the adverse party did not participate in the arbitration hearing without raising the objection; but the fact that the relief was such that it could not or would not be granted by a court of law or equity is not ground for vacating or refusing to confirm the award.B. In declining to confirm an award on grounds other than stated in paragraph 5 of subsection A the court may order a rehearing before new arbitrators chosen as provided in the agreement, or in the absence thereof, by the court in accordance with section 12-1503, or if the court declines to confirm the award on grounds set forth in paragraphs 3 and 4 of subsection A the court may order a rehearing before the arbitrators who made the award or their successors appointed in accordance with section 12-1503. The time within which the agreement requires the award to be made is applicable to the rehearing and commences from the date of the order.
