Arbitrators, as adjudicators of commercial disputes, have circumscribed authority. They are retained by the parties to resolve their disputes and for no other purpose. The doctrine of functus officio (that is, having performed the office) holds that once an arbitrator renders a decision regarding the issues submitted, in the form of an award, he or she lacks any power to reexamine that decision. In most instances, functus officio prevents further action by the tribunal, meaning that the parties—to their dismay, or delight, depending on their position in the case—are stuck with the award, even when the arbitrators have acknowledged the award contained an error and would like to correct it. A recent Second Circuit decision, however, shows that this doctrine is not necessarily as limited as many may believe. See Smarter Tools v. Chongqing SENCI Import & Export Trade, 57 F. 4th 372 (2d Cir. 2023).
