The Supreme Court ruled Monday that two districts redrawn by North Carolina officials amounted to unconstitutional racial gerrymandering.

The 5-3 decision in Cooper v. Harris tossed out the districts drawn by Republican officials after the 2010 census. Justice Elena Kagan wrote the court’s opinion and was joined by Justices Clarence Thomas, who wrote a concurring opinion, and Ruth Bader Ginsburg, Sonia Sotomayor and Stephen Breyer. Justice Neil Gorsuch did not participate.
