Baker v. Carr
Citation and Court
369 U.S. 186 (1962). United States Supreme Court. Justice Brennan, writing for the Court (6-2).
Facts
Tennessee voters challenged the state’s legislative apportionment, which had not been updated since 1901 despite massive population shifts. Rural districts with tiny populations had the same legislative representation as urban districts with far larger populations. The federal district court dismissed on two grounds: lack of subject matter jurisdiction and the political question doctrine, reasoning that apportionment was a non-justiciable political matter committed to the legislature. The plaintiffs appealed.
Issue
Are challenges to legislative malapportionment justiciable under the federal courts’ Article III jurisdiction, or are such challenges barred by the political question doctrine?
Holding
Reapportionment claims raise justiciable questions under the Equal Protection Clause. The political question doctrine does not bar federal courts from reviewing whether a state’s apportionment scheme violates the Constitution.
Rule / Doctrine
Six-Factor Political Question Doctrine Test: A political question exists — and the courts must stay out — when there is: (1) a textually demonstrable constitutional commitment of the issue to a coordinate political department; (2) a lack of judicially discoverable and manageable standards; (3) impossibility of deciding without an initial policy determination of a kind clearly for nonjudicial discretion; (4) impossibility of independent resolution without disrespecting coordinate branches; (5) unusual need for unquestioning adherence to a political decision already made; or (6) potential embarrassment from multifarious pronouncements by various departments. Legislative reapportionment implicates none of these — it is governed by Equal Protection principles courts can apply.
Significance
Baker v. Carr is the foundational justiciability case in constitutional law. It opened federal courts to reapportionment challenges, leading directly to Reynolds v. Sims and the “one person, one vote” revolution. The six-factor test remains the authoritative framework for identifying non-justiciable political questions. The case also signaled the Warren Court’s willingness to supervise the structure of democratic representation.
