The United States Constitution requires that 'Full Faith and Credit shall be given in each State to the * * * judicial Proceedings of every other State.' The case before us presents questions arising under this constitutional provision and under the federal statute enacted to implement it.

In 1956 the petitioners brought an action against the respondent in a Nebraska court to quiet title to certain bottom land situated on the Missouri River. The main channel of that river forms the boundary between the States of Nebraska and Missouri. The Nebraska court had jurisdiction over the subject matter of the controversy only if the land in question was in Nebraska. Whether the land was Nebraska land depended entirely upon a factual question-whether a shift in the river's course had been caused by avulsion or accretion. The respondent appeared in the Nebraska court and through counsel fully litigated the issues, explicitly contesting the court's jurisdiction over the subject matter of the controversy. After a hearing the court found the issues in favor of the petitioners and ordered that title to the land be quieted in them. The respondent appealed, and the Supreme Court of Nebraska affirmed the judgment after a trial de novo on the record made in the lower court. The State Supreme Court specifically found that the rule of avulsion was applicable, that the land in question was in Nebraska, that the Nebraska courts therefore had jurisdiction of the subject matter of the litigation, and that title to the land was in the petitioners. Durfee v. Keiffer, 168 Neb. 272, 95 N.W.2d 618. The respondent did not petition this Court for a writ of certiorari to review that judgment.

Durfee v. Duke/Opinion of the Court

Two months later the respondent filed a suit against the petitioners in a Missouri court to quiet title to the same land. Her complaint alleged that the land was in Missouri. The suit was removed to a Federal District Court by reason of diversity of citizenship. The District Court after hearing evidence expressed the view that the land was in Missouri, but held that all the issues had been adjudicated and determined in the Nebraska litigation, and that the judgment of the Nebraska Supreme Court was res judicata and 'is now binding upon this court.' The Court of Appeals reversed, holding that the District Court was not required to give full faith and credit to the Nebraska judgment, and that normal res judicata principles were not applicable because the controversy involved land and a court in Missouri was therefore free to retry the question of the Nebraska court's jurisdiction over the subject matter. 308 F.2d 209. We granted certiorari to consider a question important to the administration of justice in our federal system. 371 U.S. 946, 83 S.Ct. 509, 9 L.Ed.2d 496. For the reasons that follow, we reverse the judgment before us.

Durfee v. Duke/Opinion of the Court

The constitutional command of full faith and credit, as implemented by Congress, requires that 'judicial proceedings * * * shall have the same full faith and credit in every court within the United States * * * as they have by law or usage in the courts of such State * * * from which they are taken.' Full faith and credit thus generally requires every State to give to a judgment at least the res judicata effect which the judgment would be accorded in the State which rendered it. 'By the Constitutional provision for full faith and credit, the local doctrines of res judicata, speaking generally, become a part of national jurisprudence, and therefore federal questions cognizable here.' Riley v. New York Trust Co., 315 U.S. 343, 349, 62 S.Ct. 608, 612, 86 L.Ed. 885.

Durfee v. Duke/Opinion of the Court

It is not questioned that the Nebraska courts would give full res judicata effect to the Nebraska judgment quieting title in the petitioners. It is the respondent's position, however, that whatever effect the Nebraska courts might give to the Nebraska judgment, the federal court in Missouri was free independently to determine whether the Nebraska court in fact had jurisdiction over the subject matter, i.e., whether the land in question was actually in Nebraska.
