A group of voters have challenged Louisiana‘s recently enacted congressional map, alleging it commits “explicit, racial segregation of voters” in violation of the 14th and 15th amendments.

The map was signed into law by Gov. Jeff Landry (R-LA) last month to comply with a court order to create a second majority-black district after a prior map with only one black-majority district was struck down. The lawsuit, filed by 12 nonblack voters, alleged the new map unlawfully discriminates on the basis of race while dividing communities to create the “six bizarre shapes” of the districts.
