BAKER v. CARR.
186
Opinion of the Court.
An unbroken line of our precedents sustains the federal
courts' jurisdiction of the subject matter of federal constitutional claims of this nature. The first cases involved
the redistricting of States for the purpose of electing
Representatives to the Federal Congress. When the
Ohio Supreme Court sustained Ohio legislation against an
attack for repugnancy to Art. I, § 4, of the Federal Constitution, we affirmed on the merits and expressly refused
to dismiss for want of jurisdiction "In view . . . of the
subject-matter of the controversy and the Federal characteristics which inhere in it . . . ." 'Ohio ex rel. Davis
v. Hildebrant, 241 U. S. 565, 570. When the Minnesota
Supreme Court affirmed the dismissal of a suit to .enjoin
the Secretary of State of Minnesota from acting under
Minnesota redistricting legislation, we reviewed the constitutional merits of the legislation and reversed the State
Supreme Court. Smiley v. .Holm, 285 U. S. 355. And
see companion cases from the New York Court of Appeals
and the Missouri Supreme Court, Koenig v. Flynn, 285
U. S. 375; Carroll v. Becker, 285 U. S. 380. When a
three-judge District Court, exercising jurisdiction under
the predecessor of 28 U. S. C. § 1343 (3), permanently
enjoined officers of the State of Mississippi from conducting an election of Representatives under a Mississippi
redistricting act, -we reviewed the federal questions on the
merits and reversed the District Court. Wood v. Broom,
287 U. S. 1, reversing 1 F. Supp. 134. A similar decree
of a District Court, exercising jurisdiction under the same
statute, concerning a Kentucky redistricting act, was
Amendment. Douglas v. Jeannette, 319 U. S. 157; Stefanelli v.
Minard, 342 U. S. 117; ef. Nixon v. Herndon, 273 U. S. 536; Nixon
v. Condon, 286 U. S. 73; Snowden v. Hughes, 321 U. S. 1; Smith v.
