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 Mississippi’s latest districting maps fail to reflect the reality of the state’s 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.

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.

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.

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.

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 this dilutes the voting strength of Black residents in state Supreme Court elections, in violation of the Voting Rights Act and the U.S. Constitution.

The Supreme Court heard oral arguments on this case on April 24, 2024. The Court’s ultimate decision will impact access to this essential care across the country.

Massachusetts Supreme Court

Capital Punishment
Graham v. Hampden County District Attorney
Federal and state constitutional law requires prosecutors to inquire into and disclose misconduct by members of their prosecution teams. In Massachusetts, the Supreme Judicial Court has applied those principles, and others, in cases that have led to the mass exoneration of people convicted of drug crimes with the assistance of former state chemists who committed misconduct. In Graham, the ACLU and public defenders are asking the Massachusetts Supreme Judicial Court to apply those same principles to a situation where the U.S. Department of Justice has alleged a pattern or practice of misconduct by members of a police department—specifically, the Narcotics Bureau of the Springfield (MA) Police Department. The Springfield investigation was the DOJ’s sole pattern-or-practice investigation during the Trump Administration, but the DOJ has opened several such investigations during the Biden Administration. Graham appears to be the first state supreme court case in the country to consider whether DOJ pattern-or-practice findings can trigger duties under state law to investigate and disclose the misconduct alleged by the DOJ. In a major victory, the Massachusetts Supreme Judicial Court ruled in January 2024 that the Hampden County District Attorney’s Office violated its duties to disclose and inquire about exculpatory evidence of widespread misconduct by Springfield police.

Mississippi

Voting Rights
Hopkins v. Watson (Amicus)
Mississippi is home to one of the strictest felon disenfranchisement schemes in the nation. The Mississippi Constitution permanently disenfranchises citizens upon a single felony conviction for certain crimes, including minor offenses like writing a bad check. As a result, the loss of rights under Mississippi’s scheme is mandatory, permanent, and effectively irrevocable. In Hopkins, plaintiffs, a class of formerly incarcerated individuals who lost their right to vote despite completing their sentences, argued that their disenfranchisement violated the Eighth Amendment’s prohibition on cruel and unusual punishment. A three-judge panel of the U.S. Court of Appeals for the Fifth Circuit ruled in the plaintiffs’ favor and struck down Mississippi’s disenfranchisement scheme as cruel and unusual punishment. But the Fifth Circuit decided to rehear the case en banc, a rare occurrence in which a case is reconsidered by the entire panel of the circuit’s active judges.

Gino v. President and Fellows of Harvard College
In a prominent defamation suit, the ACLU is urging a trial court to rigorously apply the First Amendment rule that statements of opinion are protected, so long as speakers share the facts that led to them. Without this First Amendment protection, unchecked defamation lawsuits would silence the critics of more powerful speakers, and stifle scientific discussions and academic inquiry.
