(a) Subject to the provisions of this Article, the parties may agree on the procedure to be followed by the arbitral tribunal in conducting the proceedings.

(b) If there is no agreement under subsection (a) of this section, subject to the provisions of this Article, the tribunal shall select the rules for conducting the arbitration after hearing all the parties and taking particular reference to model rules developed by arbitration institutions or similar sources. If the tribunal is unable to decide on rules for conducting the arbitration, upon application by a party, the court may order use of rules for conducting the arbitration, taking particular reference to model rules developed by arbitration institutions or similar sources. In other matters not covered by rules, the tribunal shall conduct the arbitration in such manner as it considers appropriate. The power conferred upon the arbitral tribunal includes the power to order such discovery as it deems necessary and to determine the admissibility, relevance, materiality, and weight of any evidence. Evidence need not be limited by the rules of evidence applicable in judicial proceedings, except as to immunities and privilege. Each party shall have the burden of proving the facts relied on to support its claim, counterclaim, setoff, or defense. (1991, c. 292, s. 1; 2017-171, s. 1.)
