Whether Article III permits a citizen of one State to sue another State in the Supreme Court.
Holding
Yes. By a 4–1 vote, the Court held that Article III extends federal judicial power to a controversy between a State and a citizen of another State, including a case in which the State is the defendant.
Reasoning
The Constitution extends judicial power to “controversies between a State and citizens of another State.” Chief Justice Jay, Justice Blair, Justice Wilson, and Justice Cushing read that language according to its ordinary meaning. A dispute between a State and an out-of-state citizen remains such a controversy regardless of which side filed the suit.
The surrounding provisions confirmed that reading. Article III also covers controversies between States and provides original jurisdiction whenever a State is a party. Those provisions necessarily contemplate that a State can sometimes stand as a defendant; the Constitution did not limit the word “party” to plaintiffs.
The majority rejected the claim that state sovereignty created an implied exception. In the American constitutional system, sovereignty ultimately resided in the people, who adopted the Constitution and delegated specified powers to the national government. For matters assigned to federal judicial power, a State had accepted the limits imposed by the constitutional compact.
A central purpose of the national judiciary was to provide neutral resolution of interstate disputes and to ensure justice for citizens of different States. Allowing a State to sue citizens of other States while barring those citizens from suing the State would be inconsistent with equal justice and could generate interstate friction.
