Limits on congressional redistricting

Though the states have wide latitude in the re-drawing of congressional districts, state power over redistricting is subject to limits set by the U.S. Constitution, rulings of the federal judiciary and statutes passed by Congress. In the case of Wesberry v. Sanders, the Supreme Court of the United States established that states must draw districts that are equal in population "as nearly as is practicable." Subsequent court cases have required states to redistrict every ten years, although states can redistrict more often than that depending on their own statutes and constitutional provisions. Since the passage of the Uniform Congressional District Act (Pub. L. 90–196, 81 Stat. 581, enacted December 14, 1967), most states have been barred from using multi-member districts; all states currently use single-member districts. The Voting Rights Act of 1965 establishes protections against racial redistricting plans that would deny minority voters an equal opportunity to elect representatives of their choice. The Supreme Court case of Thornburg v. Gingles established a test to determine whether redistricting lines violate the Voting Rights Act. In some states, courts have required the creation of majority-minority districts.
