Discusses areas where Mittenthal, Meltzer, and Howlett are in accord regarding the role of law in arbitration. (See immediately previous articles.) Suggests that, in the vast majority of cases, all three approaches would reach the same result. Also suggests that courts, rather than arbitrators, enforce contracts, and that arbitrators merely interpret contracts. Notes parties could propose clauses to clarify the arbitrator’s powers, or that the arbitrator could ask the parties whether he has the authority to apply the law. Suggests most parties selected the arbitrator to interpret the contract, not the law.
