What was Baker vs Carr in 1962?

Baker v. Carr (1962) was a landmark Supreme Court case that addressed the issue of legislative district apportionment and the principle of "one person, one vote." The Court ruled that federal courts could intervene in and decide redistricting cases, thus allowing citizens to challenge unequal representation in state legislatures. This decision effectively opened the door for judicial oversight of state electoral practices, leading to significant changes in how legislative districts were drawn across the United States. The ruling emphasized the importance of equal representation in a democratic system.
