Baker v. Carr, 369 U.S. 186 (1962), was a landmark United States Supreme Court case that decided that redistricting (attempts to change the way voting districts are delineated) issues present justiciable questions, thus enabling federal courts to intervene in and to decide redistricting cases. The defendants unsuccessfully argued that redistricting of legislative districts is a "political question", and hence not a question that may be resolved by federal courts.
