Baker v. Carr holdings and principle?

• A. The Court has the authority to hear redistricting cases and established the 'one person, one vote' doctrine.
• B. Redistricting matters are entirely non-justiciable for the courts.
• C. The decision limited federal oversight over elections.
• D. It applied only to Tennessee.

Answer: (A)

The main idea here is that Baker v. Carr established that federal courts can hear cases about how state legislative districts are drawn, and it introduced the principle of "one person, one vote." The Court rejected treating apportionment as a non-justiciable political question and ruled that allegations that districts were drawn to dilute a citizen’s vote raise constitutional questions under the Equal Protection Clause, so they are suitable for judicial review. This decision laid the groundwork for districts to be based on roughly equal populations, ensuring that each vote carries comparable weight. While Reynolds v. Sims later reinforced this standard across both legislative chambers, Baker v. Carr itself marks the moment when federal courts gained authority to intervene in redistricting disputes. It also applies to all states, not just Tennessee.
