299 U.S. 304 (1936)
The United States v. Curtiss-Wright Export Corp.
Does the President have the constitutional authority to engage in foreign affairs without Congressional approval?
The President of the United States is vested with the inherent executive power to conduct foreign affairs, derived from both the U.S. Constitution and the nature of sovereignty, independent of explicit Congressional authorization.
The Supreme Court held that the President possesses broad powers in foreign affairs, which are not dependent on Congressional delegation, affirming the President's authority to enforce the arms embargo.
United States v. Curtiss-Wright Export Corp. underscores the principle that the President wields considerable authority in foreign affairs, a notion that has been repeatedly referenced in subsequent cases and legal doctrines. For law students, the case illustrates the distinctions between domestic and international powers of the President, reinforcing the idea of inherent executive authority in overseeing international relations.
