Gomillion v. Lightfoot
This case marked a change in the Supreme Court's involvement in political redistricting. Up to this point the Court had shown it was reluctant to interfere with the States when establishing political boundaries of their cities. However, this case served to show that states cannot deprive citizens of their voting rights which are protected by the Fifteenth Amendment. Although the practice of gerrymandering remained an issue after this case, the Court determined it was unconstitutional when it clearly discriminated against any particular racial group.
