A federal judge has ruled that school board districts in Georgia’s second-largest school system appear to be unconstitutionally discriminatory and must be quickly redrawn ahead of 2024′s elections.

U.S. District Judge Eleanor Ross on Thursday forbade the Cobb County school district from using a map supported by the current board’s four Republican members, finding in a preliminary injunction that the map is “substantially likely to be an unconstitutional racial gerrymander.”
