Louisiana v. Callais (Callais v. Landry)
Whether the congressional map Louisiana adopted to cure a Voting Rights Act violation in Robinson v. Ardoin is itself unlawful as a gerrymander.

Voting Rights
League of Women Voters of Massachusetts v. Trump
On March 31, 2026, President Trump issued a sweeping Executive Order titled "Ensuring Citizen Verification and Integrity in Federal Elections," seeking once again to seize control of election administration from Congress and the states. The Order directs federal agencies to compile lists of U.S. citizens and transmit them to states before every election, directs the U.S. Postal Service -- an independent agency established by Congress -- to create a list of "approved" mail voters, and instructs USPS to refuse to deliver ballots from voters not on that federally created list. If implemented, the Order would threaten the ability of millions of eligible citizens to cast their ballots, particularly military members, overseas citizens, the elderly, recently naturalized citizens, and voters with disabilities who rely on mail voting.
Missouri

Voting Rights
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.
Tennessee Supreme Court
Apr 2026
Capital Punishment
Tony Von Carruthers v. State of Tennessee
Tennessee plans to execute Tony Carruthers on May 21 even though they refuse to run a simple fingerprint comparison and DNA testing that could prove what Tony has been arguing for 30 years - that he is innocent of this crime and that Tennessee convicted and sentenced the wrong man to death.

Immigrants' Rights
Barbara v. Donald J. Trump
President Trump is attempting to undermine the promise of birthright citizenship to children born on U.S. soil. But the ACLU and partners are fighting to protect the rights of citizens that are plainly stated in the Constitution, federal statute, and reaffirmed by the Supreme Court for more than a century. We’re arguing against the Trump administration in the Supreme Court and are confident we will win.
Mississippi

Voting Rights
White v. Mississippi State Board of Elections
District lines used to elect Mississippi’s Supreme Court have gone unchanged for more than 35 years. We’re 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.

FOIA Case Seeking the Trump Administration’s Legal Justification for Deadly Boat Strikes
The Department of Justice’s Office of Legal Counsel (“OLC”) authored a legal opinion that reportedly claims to justify the Trump administration’s illegal lethal strikes on civilians in boats in the Caribbean Sea and eastern Pacific Ocean. Media reports indicate that, in addition to claiming that the strikes are lawful acts in an alleged “armed conflict” with unspecified drug cartels, the OLC opinion also purports to immunize personnel who authorized or took part in the strikes from future criminal prosecution. Because the public deserves to know how our government is justifying these illegal strikes, and why they think the people who carried them out should not be held accountable, the ACLU is seeking immediate release of the OLC legal opinion and related documents pursuant to the Freedom of Information Act.
U.S. Supreme Court

Voting Rights
Racial Justice
Allen v. Milligan
Whether Alabama’s 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.

Voting Rights
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 Commission—an agency that Congress specifically established to be bipartisan and independent—to 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.

Pennsylvania Supreme Court
Nov 2024
Criminal Law Reform
Commonwealth of Pennsylvania v. Shivers
This case in the Pennsylvania Supreme Court asks whether flight from the police in a high-crime area, without more, can justify an investigative stop. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Pennsylvania, filed an amicus brief arguing that it does not. The brief argues that the Pennsylvania Constitution supports broader protections against investigative stops than those recognized under the U.S. Constitution, and that flight in high-crime areas is not inherently more suspicious than flight elsewhere.

Ayota v. Fall
On October 31, 2024, just five days before the November 5 General Election, Cobb County announced that it had failed to send more than 3,000 absentee ballots to Cobb County voters who had timely requested them. Many of these voters are at school hundreds of miles away or have disabilities that make it all but impossible to vote in person. The ACLU and co-counsel sued on behalf of affected voters to ensure that they would not be disenfranchised because of the County's administrative error.

Aubry McMahon v. World Vision, Inc.
On October 28, 2024, the ACLU and ACLU of Washington filed an amicus brief in the U.S. Court of Appeals for the Ninth Circuit supporting affirmance of a Washington district court decision holding that a religiously affiliated nonprofit organization violated Title VII and the Washington State antidiscrimination law when it rescinded a hiring candidate’s job offer because she is a woman married to a person of the same sex. Should the Ninth Circuit accept the organization’s First Amendment defense—that religious organizations can discriminate on any basis so long as it is grounded in their religious belief—it would gut employment protections for LGBTQ individuals and pave the way for religious organizations to discriminate on the basis of not only sex, sexual orientation, and gender identity but also other protected characteristics like race, color, and national origin.

Voting Rights
American Civil Liberties Union of South Carolina v. State Election Commission
The South Carolina Department of Motor Vehicles (SCDMV) has unlawfully denied young, eligible South Carolinians the opportunity to register to vote. Under South Carolina law, individuals who are 17 years old may register to vote and vote in primary elections so long as they (1) will turn 18 on or before the next general election, and (2) otherwise meet the qualifications for voting. An administrative error in the SCDMV's processes, however has stopped the Department from transmitting the proper paperwork to complete all registration information to the South Carolina Elections Commission. As a result, thousands of young voters who did everything right and should have been registered to vote have not been added to the state's voter rolls in the runup to the 2024 general election. ACLU and ACLU of South Carolina sued, asking the court to ensure that these new voters are registered and properly notified in time for them to vote in the November 2024 election.
