There has been a great deal of inconsistency in the area of arbitration discovery, especially relating to nonparty witnesses. This Article argues that these inconsistencies have led to two unresolved issues: (1) federal courts disagree as to whether the Federal Arbitration Act authorizes nonparty subpoenas outside of an actual arbitration hearing; and (2) properly issued subpoenas to nonparties residing outside of the arbitration site’s jurisdiction may not be enforceable due to a gap between the Federal Arbitration Act and the Federal Rules of Civil Procedure. This Article discusses how recent caselaw has dealt with both of these issues. This Article also explains how these inconsistencies have led to limited, if any, prehearing nonparty discovery, and how properly issued subpoenas to nonparty witnesses may lack enforcement power. This Article suggests that Congress amend the Federal Arbitration Act to expand nonparty discovery and to allow for subpoena enforcement from the district court in a witness’s jurisdiction, and this Article then explores the benefits that may derive from these changes, suggesting that the amendment would make the arbitration process more just and consistent.
