When political or electoral districts are drawn with the purpose of giving one political group an advantage over another, a practice which often results in districts with bizarre or strange shapes. Frequently referred to as "political gerrymandering" or "jurisdictional gerrymandering." see, e.g. United States v. Hays, 515 US 737 (1995) and Miller v. Johnson, 515 US 900 (1995).
