## Facts

- Tennessee’s constitution required periodic reapportionment of seats in the General Assembly, but the governing apportionment statute had remained unchanged since 1901 despite major population shifts.
- Qualified voters from several Tennessee counties sued state election officials under 42 U.S.C. §§ 1983 and 1988, alleging that outdated districts diluted their votes compared to voters in less populous districts.
- Plaintiffs claimed the resulting vote dilution denied them equal protection under the Fourteenth Amendment.
- Plaintiffs sought declaratory relief invalidating the apportionment scheme and injunctive relief to prevent further elections under it.
- A three-judge federal district court dismissed for lack of subject-matter jurisdiction and for failure to state a claim, treating the dispute as a nonjusticiable political question.

## Issues

1. Whether the federal district court had subject-matter jurisdiction over an Equal Protection challenge to state legislative apportionment brought under § 1983.
2. Whether the plaintiffs, as voters alleging vote dilution, had standing to sue.
3. Whether an Equal Protection challenge to malapportionment presents a nonjusticiable political question.

## Decision

- The Supreme Court reversed and remanded.
- Federal courts have jurisdiction to hear the Equal Protection claim asserted under § 1983.
- The plaintiffs had standing because they alleged a personal injury—dilution of voting power—rather than a generalized grievance.
- The complaint presented a justiciable constitutional controversy; it was not barred by the political question doctrine.
- The Court did not decide the merits of whether Tennessee’s apportionment violated equal protection, but held plaintiffs were entitled to adjudication.

## Legal Principles

- Equal Protection challenges to state legislative apportionment may be justiciable and are not categorically excluded by the political question doctrine.
- Political question analysis turns on factors including: (1) a textually demonstrable constitutional commitment to another branch, and (2) absence of judicially discoverable and manageable standards, among related considerations.
- Vote-dilution allegations by qualified voters can constitute a concrete, personal injury sufficient for Article III standing.
- A § 1983 action may be used to seek relief for alleged deprivations of federal constitutional rights caused by state election practices.

## Conclusion

Baker v. Carr held that voters’ Equal Protection challenges to state legislative malapportionment are within federal judicial power to decide, establishing jurisdiction, recognizing standing based on vote dilution, and rejecting a blanket political-question bar while leaving the merits for further proceedings on remand.
