Final answer:
The statement is true. Even though an arbitrator has the legal authority to subpoena witnesses and documents, they may not make an adverse inference if the subpoena is not complied with.
Step-by-step explanation:
The statement is true.
Even though an arbitrator has the legal authority to subpoena witnesses and documents, they do not have the power to make an adverse inference if the subpoena is not complied with. An adverse inference is a legal presumption that the evidence being sought would have been unfavorable to the party who failed to produce it. In an arbitration process, the arbitrator's role is to facilitate the resolution of disputes between parties and make a decision based on the evidence presented, but they do not have the power to sanction or penalize parties for not complying with subpoenas.
