26. The decision is made by a majority of the members of the council; should there not be a majority, the decision is made by the chair.

The fact that an arbitrator refuses or is unable to sign must be mentioned in the decision, which has the same effect as though signed by all the arbitrators. A dissenting member may state the reasons for his or her refusal in the decision.
