Missouri v. U.S. Department of Commerce
A coalition of civil rights and immigrant-rights organizations has moved to intervene as defendants in a lawsuit that threatens to dismantle the Constitutionās long-standing requirement that the decennial census count all people living in the United States. Missouri asks the court to exclude undocumented immigrants and people living in the country on temporary visas from the census count used to determine congressional representationāan unprecedented move that would upend more than two centuries of constitutional practice.

White v. Mississippi State Board of Elections
District lines used to elect Mississippiās Supreme Court have gone unchanged for more than 35 years. Weāre suing because the current lines crack the Mississippi Delta and dilute the voting strength of Black Mississippians in state Supreme Court elections, in violation of the Voting Rights Act.

Allen v. Milligan
Whether Alabamaās congressional districts violate Section 2 of the Voting Rights Act because they discriminate against Black voters. We succeeded in winning a new map for 2024 elections which, for the first time, has two congressional district that provide Black voters a fair opportunity to elect candidates of their choosing despite multiple attempts by Alabama to stop us at the Supreme Court. Despite this win, Alabama is still defending its discriminatory map, and a trial was held in February 2025 to determine the map for the rest of the decade.
In May 2025, a federal court ruled that Alabama's 2023 congressional map both violates Section 2 of the Voting Rights Act and was enacted by the Alabama Legislature with racially discriminatory intent.

League of Women Voters Education Fund v. Trump
On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commissionāan agency that Congress specifically established to be bipartisan and independentāto require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.
On behalf of leading voter registration organizations and advocacy organizations, the ACLU and co-counsel filed a lawsuit to block the Executive Order as an unconstitutional power grab.

State Board of Election Commissioners v. Mississippi State Conference of the NAACP
Mississippi has a growing Black population, which is already the largest Black population percentage of any state in the country. Yet. Black Mississippians continue to be significantly under-represented in the state legislature, as Mississippiās latest districting maps fail to reflect the reality of the stateās changing demographics. During the 2022 redistricting process, the Mississippi legislature refused to create any new districts where Black voters have a chance to elect their preferred representative. The current district lines therefore dilute the voting power of Black Mississippians and continue to deprive them of political representation that is responsive to their needs and concerns, including severe disparities in education and healthcare.

Wise v. Missouri
In unprecedented fashion, the State of Missouri has redrawn the district lines used for electing members of Congress for a second time this decade. These new district lines are gerrymandered and will harm political representation for all Missourians, particularly Black residents in Kansas City, who have been divided along racial lines.

United States v. Nago
The Department of Justice sued the Hawaiāi Secretary of State, demanding the state produce its full, unredacted voter file, which contains highly sensitive and personal data on every voter in the state. This suit appears to be part of the federal government's efforts to build a national voter database without congressional authorization and to improperly question the validity of state voter rolls.

Watson v. Republican National Committee (Amicus)
In 2020, in a nearly unanimous bipartisan vote, Mississippi joined eighteen other states in accepting mail ballots postmarked by Election Day that arrived after Election Day (in Mississippiās case, up to five business days). This lawsuit by partisan actors seeks to disenfranchise these voters whose ballot is mailed by Election Day butāthrough no fault of their ownādoes not arrive until afterwards. In Mississippi, this harm will fall disproportionately on voters with disabilities, older voters, and other communities that rely upon absentee voting. Twisting the words and meaning of Congress, the RNC argues that three longstanding federal laws that set a uniform election day for federal races require that ballot may only be counted if they are received by election officials by Election Day. If accepted, this radical argument would not only disenfranchise thousands upon thousands of voters in Mississippi and eighteen other states, but also upend election administration in every state.
