The U.S. Supreme Court on Friday decided to hear two partisan gerrymandering cases: a North Carolina case spearheaded by Atlanta attorney Emmet Bondurant and the Maryland case that inspired it.

At its Friday conference, the high court decided it will hear North Carolina Republican legislators’ appeal of a 2018 three-judge ruling that found partisan gerrymandering used to corral the majority of Democratic voters in just three districts in 2016 was unconstitutional. The case, Rucho v. Common Cause, was originally filed in 2016 in U.S. District Court for the Middle District of North Carolina.
