2020-2024
On June 27, 2025, the U.S. Supreme Court scheduled Louisiana v. Callais for reargument in its next term.[4] In August 2025, the Court scheduled arguments for October 15, 2025.[5]
The Court first heard oral arguments in the case on March 24, 2025.[6] On November 4, 2024, the U.S. Supreme Court agreed to hear Louisiana v. Callais (formerly Callais v. Landry) consolidated with Robinson v. Callais — two appeals from the U.S. District Court for Western Louisiana decision that struck down the state's new congressional map. The Court noted probable jurisdiction and allotted one hour for oral argument.[7][8]
On May 15, 2024, the U.S. Supreme Court blocked an April 30 ruling by the U.S. District Court for Western Louisiana striking down the state's congressional map. As a result, the map was used for Louisiana’s 2024 congressional elections.[9] According to ScotusBlog,
| “ | In a brief unsigned order the justices blocked a ruling by a federal court that had barred the state from using the new map on the ground that legislators had relied too heavily on race when they drew it earlier this year. The order cited an election doctrine known as the Purcell principle – the idea that courts should not change election rules during the period just before an election because of the confusion that it will cause for voters and the problems that doing so could cause for election officials. The lower court’s order will remain on hold, the court indicated, while an appeal to the Supreme Court moves forward.[9][10] | ” |
Gov. Jeff Landry signed the congressional map into law on January 22 after a special legislative session. The state House of Representatives voted 86-16 and the state Senate voted 27-11 to adopt this congressional map on January 19.[11][12]
According to NPR, "Under the new map, Louisiana's 2nd District, which encompasses much of New Orleans and surrounding areas, will have a Black population of about 53%. Democratic U.S. Rep. Troy Carter represents that district, which has been Louisiana's only majority-Black district for several years. Louisiana's 6th District now stretches from parts of Shreveport to Baton Rouge and will have a Black population of about 56%."[13]
On November 10, 2023, a three-judge panel of the Fifth Circuit Court of Appeals vacated a 2022 injunction that blocked the implementation of Louisiana’s congressional district maps, for violating the Voting Rights Act by diluting the power of African American voters. The court also issued a deadline for the state to enact new maps for the 2024 election cycle.[14] On November 30, 2023, the U.S. District Court for Middle Louisiana extended the deadline for the creation of new maps that comply with the Voting Rights Act to January 30, 2024.[15] Gov. Jeff Landry called a special session of the Louisiana state legislature on January 15, 2024 — days after he assumed office on January 8 — to draw new maps in compliance with the court's order.[16]
How does redistricting in Louisiana work? In Louisiana, both congressional and state legislative districts are drawn by the state legislature. These lines are subject to veto by the governor. In the event that the legislature is unable to approve state legislative district boundaries, the state supreme court must draw the lines. There is no such practice that applies to congressional districts.[17]
The state legislature has adopted guidelines for redistricting. These guidelines suggest that both congressional and state legislative districts be contiguous and "respect recognized political boundaries and the natural geography of the state to the extent practicable." These guidelines are non-binding; as such, the legislature may alter them at its discretion.[17]
Below are the congressional maps in effect before and after the 2020 redistricting cycle. The map on the right was in effect for Louisiana’s 2024 congressional elections.
