26. The award shall be rendered by a majority of the members of the council of arbitration; failing a majority, the award shall be rendered by the chair.
The award must be reasoned and signed by the single arbitrator or the concurring arbitrators. If an arbitrator refuses or is unable to sign, the award shall indicate that fact and the award shall have the same effect as though signed by all the arbitrators. However, a dissenting member may enter in the award the reasons for his or her refusal.
