Guaranty Trust Company v. United States

Guaranty Trust Co. of New York v. United States was a 1934 Supreme Court case addressing whether federal courts could hear cases involving claims against the government when those claims were based on state law and could have been previously litigated in state courts. The Court held that federal courts could not hear such cases if they involved issues already resolved in state courts, emphasizing respect for state court judgments and preventing duplicative litigation. This case helped define the boundaries of jurisdiction and the relationship between federal and state courts regarding legal disputes.
