Mandeville v. Canterbury

Background

A woman who says she is a California resident claimed an interest in a trust created by a will probated in Illinois and sued in federal court in Northern Illinois to have the will construed and to force trustees to account and turn over her share. The trust includes land in Minnesota, Wisconsin, and Illinois. After she began the federal suit, the trustees filed separate suits in Minnesota and Wisconsin state courts to decide rights in the land in those states, and one trustee filed a probate proceeding in Rock County, Wisconsin. The federal district court issued a temporary injunction stopping the Minnesota and Wisconsin suits and pausing the Wisconsin probate action, but it allowed probate and tax determinations to continue.

Reasoning

The Court reviewed the ban in the Judicial Code on federal courts issuing injunctions to stop state-court proceedings and the long-recognized narrow exception for cases that are in rem or quasi in rem, where a court must control the property itself to decide rights. The Court concluded the Illinois federal suit was a personal action against trustees and claimants and did not require the federal court to take possession or control of the out-of-state land. Because the case did not fit the in rem exception, the federal court had no power to enjoin the state suits. The Court therefore reversed the Court of Appeals and directed the federal court to vacate the injunction.

Real world impact

State courts in Minnesota and Wisconsin may proceed to decide who owns or has rights in the land located in their states. The decision limits when federal courts can block parallel state actions, especially involving out-of-state property. The injunction against the state proceedings was lifted, allowing state adjudication to continue.
