Worcester County Trust Co. v. Riley

Background

An executor named in a Massachusetts will, handling assets partly in Massachusetts and partly in California, asked a federal court to use the federal interpleader law to sort out rival claims by both states to collect death taxes. The executor sought to deposit the funds and have the court decide which state the decedent was domiciled in, determine the tax due, and stop either state from separately trying to collect the tax.

Reasoning

The Court examined whether that federal interpleader suit could be used when two states, through their tax officers, each claim the right to collect inheritance taxes. The Justices held that because the California and Massachusetts officials would be acting under state law and seeking judicial assessments in their state courts, an injunction preventing their actions would be equivalent to a suit against the states themselves. The opinion emphasized that the complaint did not claim any state statute was unconstitutional or that officials were acting outside their lawful authority, so the Eleventh Amendment forbade the federal suit.

Real world impact

The ruling means an executor cannot force a single federal resolution of rival state inheritance-tax claims by suing state tax officers under the Interpleader Act when the suit would restrain state action. Competing claims over domicile and tax liability remain for state courts to decide, and the decision does not resolve the underlying tax or domicile questions on the merits.
