Worcester County Trust Co. v. Riley

Background

An executor named in a Massachusetts will sought to use the federal Interpleader Act to resolve competing claims from Massachusetts and California tax officials over death taxes. The decedent left bank accounts and other intangible property in both states. The executor sued in federal court seeking to have the states interplead, determine the decedent’s domicile, deposit the funds, and get a discharge and injunction against double collection. California officials moved to dismiss, arguing the Eleventh Amendment bars suits that are effectively against a state. The district court issued a temporary injunction; the Court of Appeals reversed.

Reasoning

The core question was whether the federal interpleader law could be used to force two states to litigate competing inheritance tax claims in federal court. The Court said no: the challenged actions by the state tax officers were steps taken under state law and through state courts, so restraining them would be restraining the state itself. The executor did not allege that any state statute was unconstitutional or that the officials would act outside lawful authority. The opinion distinguished cases that allow federal suits when state officials are enforcing unconstitutional laws, and it said the Interpleader Act’s use here would amount to a forbidden suit against the state.

Real world impact

The decision prevents an executor from using federal interpleader to avoid state-court processes when state tax officials act under state statutes. Competing domicile and tax claims between states must generally be fought in the appropriate state proceedings, unless a federal suit challenges an official’s action as unconstitutional. The Court did not rule on other features or future applications of the Interpleader Act.
