Baker v. Carr (369 U.S. 186 1962) was a case before the Supreme Court of the United States which decided that reapportionment issues (attempts to change the way voting districts are deliminated) does present a federal question, thus enabling federal courts to decide reapportionment cases. The plaintiffs unsuccessfully argued this is a political question and is not a federally justiciable question.
