On Monday, the Supreme Court ruled that the gerrymandering of two North Carolina congressional district maps was done on racial grounds to yield a Republican advantage and was thus unconstitutional. The court ruled 8-0 to strike down the District 1 map and 5-3 to strike down the District 12 map, with Justices Samuel Alito, Chief Justice John Roberts, and Justice Anthony Kennedy dissenting from the latter ruling, CNN reports. Justice Clarence Thomas joined the court's liberals on District 12 while Justice Neil Gorsuch did not participate, as the case was argued before he was confirmed to the court, Bloomberg reports.
Republicans have been accused of drawing districts to illegally concentrate black voters, who are typically liberal, and consequently make the surrounding districts more conservative, USA Today reports. The unconstitutional North Carolina congressional maps were used until the 2014 election, and the Supreme Court rulings uphold a new map that was ordered for 2016.
