24 SHELBY COUNTY v. HOLDER GINSBURG, J., dissenting stances exists under which the Act would be valid.” United States v. Salerno, 481 U. S. 739, 745 (1987). “[U]nder our constitutional system[,] courts are not roving commissions assigned to pass judgment on the validity of the Nation’s laws.” Broadrick v. Oklahoma, 413 U. S. 601, 610–611 (1973). Instead, the “judicial Power” is limited to deciding particular “Cases” and “Controversies.” U. S. Const., Art.

Yet the Court’s opinion in this case contains not a word explaining why Congress lacks the power to subject to preclearance the particular plaintiff that initiated this lawsuit—Shelby County, Ala­ bama. The reason for the Court’s silence is apparent, for as applied to Shelby County, the VRA’s preclearance requirement is hardly contestable. Alabama is home to Selma, site of the “Bloody Sunday” beatings of civil-rights demonstrators that served as the catalyst for the VRA’s enactment.

If the Act passed, he foresaw, progress could be made even in Alabama, but there had to be a steadfast national commitment to see the task through to comple­ tion. In King’s words, “the arc of the moral universe is long, but it bends toward justice.” G. May, Bending To­ ward Justice: The Voting Rights Act and the Transfor­ mation of American Democracy 144 (2013). History has proved King right. Although circumstances in Alabama have changed, serious concerns remain. Between 1982 and 2005, Alabama had one of the highest rates of successful §2 suits, second only to its VRA-covered
