TALLAHASSEE, Fla. — A congressional map approved by Gov. Ron DeSantis and drawn by his staff is unconstitutional because it breaks up a district where Black voters can choose their representatives, a judge said Wednesday.

Leon County Circuit Judge Layne Smith said he would issue a formal order Thursday or Friday to keep the maps from taking effect in November’s election. He made it clear he would rule in favor of voting rights groups challenging the maps.

Smith said the order will likely replace the DeSantis map with one of two that the Legislature included in a bill and sent to DeSantis in March. The governor vetoed the bill and later called the Legislature back into special session. The Republican-dominated House and Senate chose not to draw a new map, and instead passed the DeSantis map.

The challenge focuses on a north Florida district now held by Democratic U.S. Rep. Al Lawson. The district runs from Jacksonville west more than 200 miles (322 kilometers) to Gadsden County, and nearly half of its population is Black.

DeSantis’ proposal prompted a protest by Black House members as the chamber was preparing to vote on the maps.

Smith said he will issue his order as soon as he can so the state can immediately appeal it. It may be the conservative state Supreme Court that ultimately resolves the dispute.

Smith said that while the DeSantis map is more compact, the issue of allowing Black voters to choose their representatives is more important.

“The district that has since been enacted and signed into law by the governor does disperse 367,000 African American votes between four different districts," Smith said in a video call with both sides. “The African American population is no way near a plurality or a majority.”

The governor’s office drew up a map it described as neutral on race and party affiliation, and which it said abided by both the state and federal constitutions.

Smith said his ruling will be based on the state constitution, not the U.S. Constitution.

DeSantis' communications director, Taryn Fenske, gave a statement to Spectrum News hours after the judge's announcement was made public. 

“As Judge Smith implied, these complex constitutional matters of law were always going to be decided at the appellate level. We will undoubtedly be appealing his ruling and are confident the constitutional map enacted by the Florida Legislature and signed into law passes legal muster. We look forward to defending it," Fenske said in an official statement. 

Critics of the governor's efforts were also quick to add to the discourse. Florida Congressman Al Lawson (D-District 5) said that he was "pleased" with the decision before adding, "The judge recognizes that this map is unlawful and diminishes African Americans’ ability to elect representatives of their choice."

“It is critical to maintain congressional District 5 so minority voters have a voice at the ballot box in November. I am optimistic that future courts will also do what is right," Lawson continued in an official release
