By a 7-2 decision, the Supreme Court sided with Attorney General Nicholas Katzenbach, reversed the District Court, and held that Section 4(e) was constitutional. Writing the majority opinion, Justice Brennan stressed that Section 5 of the amendment is "a positive grant of legislative power authorizing Congress to exercise its discretion in determining the need for and nature of legislation to secure Fourteenth Amendment guarantees." Justice Brennan applied the appropriateness standard of "McCulloch v. Maryland" (1819) to determine whether the legislation passed constitutional muster.
