Redistricting is the process of drawing new congressional and state legislative district boundaries. This article summarizes congressional and state legislative actions in each state in the 2020 cycle.

Status of congressional redistricting

As of August 2025, congressional maps in the following states had been struck down due to ongoing litigation or were required to be redrawn before the 2026 elections.

Georgia

On December 8, 2023, Governor Brian Kemp (R) signed revised congressional maps into law. Legislators in the Georgia House of Representatives voted 98-71 to adopt the new congressional map on December 7. The Georgia State Senate voted 32-22 to adopt the congressional map on December 5.[1][2]

On October 26, 2023, the United States District Court for the Northern District of Georgia ruled that the state's congressional and legislative district boundaries violated the Voting Rights Act and enjoined the state from using them for future elections.[3] The court directed the Georgia General Assembly to develop new maps by December 8, 2023.[3]

On December 28, 2023, the U.S. District Court for the Northern District upheld the maps enacted on December 8, which were later used in the 2024 elections, and found them in compliance with the Voting Rights Act.[4]

“ The Court finds that the General Assembly fully complied with this Court’s order requiring the creation of a majority-Black congressional district in the region of the State where vote dilution was found. The Court further finds that the elimination of 2021 CD 7 did not violate the October 26, 2023 Order. Finally, the Court declines to adjudicate Plaintiffs’ new Section 2 claim based on a coalition of minority voters. Hence, the Court OVERRULES Plaintiffs’ objections ... and HEREBY APPROVES SB 3EX.[5][6] ”

The district court's approval of remedial state legislative maps was appealed to the Eleventh Circuit Court of Appeals. Oral argument was held on January 23, 2025.[7]

Louisiana

On June 27, 2025, the U.S. Supreme Court scheduled Louisiana v. Callais for reargument in its next term.[8] In August 2025, the Court scheduled arguments for October 15, 2025.[9]

The Court first heard oral arguments in the case on March 24, 2025.[10] 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.[11][12]

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.[13] 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.[13][6] ”


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.[14][15]

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%."[16]

Ohio

On March 2, 2022, the Ohio Redistricting Commission approved a redrawn congressional map in a 5-2 vote along party lines, meaning the map lasted for four years.[17] On March 18, the Ohio Supreme Court ruled that it did not have jurisdiction to overturn the map before the state's primary elections as part of the legal challenge that overturned the initial congressional map.[18] This map took effect for Ohio's 2022 congressional elections.

Utah

Utah enacted new congressional districts on November 12, 2021, after Gov. Spencer Cox (R) signed a map proposal approved by the House and the Senate. The enacted map was drafted by the legislature and differed from a proposal the Utah Independent Redistricting Commission released on November 5, 2021.[19] The congressional map passed the Utah House 50-22 on November 9, 2021, with five Republicans and all Democratic House members voting against it. The Senate approved the map on November 10, 2021, in a 21-7 vote. Before signing the congressional map, Cox said he would not veto any maps approved by the legislature. He said, "The Legislature is fully within their rights to actually make those decisions and decide where they want to draw those lines."[20] This map took effect for Utah's 2022 congressional elections.

The Utah Supreme Court ruled on July 11, 2024, that the legislature's override of Proposition 4 likely violated voters' constitutional right to participate in government.[21] The Court returned the case to Third District Court Judge Dianna Gibson to determine whether the legislature's changes to the ballot initiative were "narrowly tailored to advance a compelling government interest."[22] On August 25, 2025, Gibson struck down the state's congressional map, writing, "The nature of the violation lies in the Legislature’s refusal to respect the people’s exercise of their constitutional lawmaking power and to honor the people’s right to reform their government."[23] On September 15, 2025, the Utah Supreme Court rejected the legislature's appeal to pause the district court ruling, allowing plans to redraw the map by November 10, 2025, to proceed.[24]


Status of state legislative redistricting

As of August 2025, legislative maps in the following states had been struck down due to ongoing litigation or were required to be redrawn before the 2026 elections.

Alabama

On August 22, 2025, the district court struck down the state senate map as a violation of Section 2 of the Voting Rights Act.[25]

Alabama enacted state legislative maps for the state Senate and House of Representatives on Nov. 4, 2021, after Gov. Kay Ivey (R) signed the proposals into law.[26] Senators approved the Senate map on Nov. 1 with a 25-7 vote.[27] Representatives approved the Senate map on Nov. 3 with a 76-26 vote.[26] For the House proposal, representatives voted 68-35 in favor on Nov. 1 and senators followed on Nov. 3 with a 22-7 vote.[28] These maps took effect for Alabama's 2022 legislative elections.

Georgia

The district court's approval of remedial state legislative maps was appealed to the Eleventh Circuit Court of Appeals. Oral argument was held on January 23, 2025.[29]

Governor Kemp (R) signed revised legislative maps into law on December 8, 2023. Legislators in the Georgia House of Representatives voted 98-71 to adopt the new state legislative maps on December 5. The Georgia State Senate voted 32-23 to adopt the state legislative maps on December 1. For more information about the enacted legislative maps, click here.[1][2]

On October 26, 2023, the United States District Court for the Northern District of Georgia ruled that the state's congressional and legislative district boundaries violated the Voting Rights Act and enjoined the state from using them for future elections.[3] The court directed the Georgia General Assembly to develop new maps by December 8, 2023.[3]

Louisiana

On February 19, 2024, the state appealed a U.S. District Court for Middle Louisiana decision that struck down the state's legislative maps.[30]

The lower court's February 8, 2024, ruling found the state's legislative maps to be in violation of the Voting Rights Act.[31][32] According to the ruling, the court found the following:

“ [T]he Enacted State House and Senate Maps crack or pack large and geographically compact minority populations such as Black voters in the challenged districts 'have less opportunity than other members of the electorate to participate in the political process and to elect representatives of their choice,' and the Illustrative Plan offered by the Plaintiffs show that additional opportunity districts can be 'reasonable configured.'[32][6] ”

Tennessee

On November 22, 2023, the Davidson County Chancery Court struck down the state Senate map, declaring it unconstitutional. The court ordered the state to create a new state Senate map by January 31, 2024.[33] The Tennessee Supreme Court stayed the lower court's order, keeping the state Senate map in place for the 2024 elections.[34]

On April 13, 2022, the Tennessee Supreme Court reversed a ruling by the Davidson County Chancery Court on April 6, blocking the same state senate map.[35] Three individuals filed the original lawsuit on February 23, saying the state's legislative maps violated the Tennessee constitution by non-consecutively numbering Senate districts in Davidson County. The state filed a motion to appeal on April 7, with the Tennessee Court of Appeals.[36]
