The U.S. Court of Appeals for the Second Circuit has ruled that a Connecticut federal court has jurisdiction to hear a constitutional challenge to the state’s 2011 redistricting plan’s method of counting prisoners in districts which they are incarcerated, rather than the districts in which they permanently reside.

A unanimous three-judge panel of the Manhattan-based appeals court said Tuesday that the suit, filed by the National Association for the Advancement of Colored People, alleged an ongoing violation of the Fourteenth Amendment’s “one person, one vote” principle and thus could proceed in federal court.
