§ 171.042.Majority Action by Arbitrators

A default rule for panels, stated in a single line.

A majority exercises the powers of the arbitrators. On a three-member panel, two agreeing arbitrators can act.

The rule is a default, not a command. It yields to the agreement to arbitrate and to other provisions of the chapter.

Parties change it often. Institutional rules commonly give the presiding arbitrator authority over procedural questions, and an agreement can require unanimity.

Without the default, a divided panel would be stuck. A dissenting arbitrator could block every ruling by declining to join it.

Section 171.043 carries the same idea into the hearing. All the arbitrators conduct the hearing, and a majority may determine a question and render a final award.

Section 171.053 applies it to the award document, which must be signed by each arbitrator joining in it — the signatures show who made up the majority.

A sole arbitrator makes the question disappear, which is one reason many agreements provide for one.

The international chapter states the same default in Section 172.081, with an express exception letting a presiding arbitrator decide procedural questions.

The rule says nothing about who must hear the evidence. That is Section 171.043’s subject, and the two work together: all the arbitrators hear, a majority decides.

Nothing here requires the majority to agree on reasons. The chapter asks for a written award signed by those joining it, not for an opinion the panel shares.
