Many states are seeing rulings on redistricting cases including at the country’s Supreme Court. From the recent announcement by the Brennan Center for Justice at NYU School of Law:

Since our March litigation update, a three-judge panel ruled that several districts in Texas’ 2011 congressional and legislative maps were unconstitutional racial gerrymanders, a group of plaintiffs filed a new racial and partisan gerrymandering lawsuit in Georgia, and plaintiffs in a partisan gerrymandering lawsuit in Virginia appealed a circuit court’s ruling to the state Supreme Court.
