The lawsuit, filed in state court in Leon County, alleges the card is a Republican gerrymander and violates the Fair Districts Amendment to the Florida Constitution by diminishing the power of black voters. Plaintiffs are asking the court to rule that the map or the individual districts violate the Fair Districts Amendment and to order the adoption of a new congressional map.
The challenge was filed by several Florida voters, as well as the League of Women Voters Florida, Black Voters Matter, Florida Rising and Equal Ground Florida.
The approved map could help Florida Republicans win up to four seats in the US House of Representatives in November.
The map dismantles the state’s 5th congressional district, currently represented by Democrat Al Lawson, which connects black communities from Tallahassee to Jacksonville. Instead, Jacksonville, the city with the largest African-American population in Florida, is divided into two Republican-leaning districts.
DeSantis argued that these districts are racist and suggested that they are unconstitutional.
Several black members of the Florida House staged a protest during the debate on Thursday, forcing an informal recess before Republican members continued the process by shutting down the debate and holding the vote during the protest.
The Republicans currently hold a 16-11 advantage in the US House delegation in Florida. The state added a 28th district following the 2020 U.S. Census.
