Voting Rights
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.

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 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.

Roland Branch v. State of Maryland
This petition to the Supreme Court of Maryland asked the court to reconsider its adherence to Whren v. U.S., 517 U.S. 806 (1996), which declared that a traffic stop undertaken for pretextual reasons does not violate the Fourth Amendment to the U.S. Constitution so long as the police have probable cause to believe that a traffic violation occurred. The ACLU, alongside the ACLU of Maryland, filed an amicus brief in support of the defendant’s petition, in which the ACLU argued that the court should take up the question of whether pretextual stops violate the Maryland Constitution. In September 2024, the Court denied the petition.

State v. Wright
This case in the North Carolina Supreme Court involves the question of whether the police violated the U.S. Constitution when they searched the defendant, Mr. Wright’s, backpack even after he repeatedly said no to the search requests. The ACLU alongside the ACLU of North Carolina filed an amicus brief arguing that the search was unconstitutional because Mr. Wright’s eventual “consent” was the result of police coercion. Our brief urges the court to consider the totality of the circumstances that make one more susceptible to coercion, including race and poverty.

Florida Supreme Court

Capital Punishment
Michael Jackson v. State of Florida
This case gets at the very heart of our right to a jury trial. Traditionally and historically, the right to a jury trial has promised that a person could not be punished unless every single person in a group of one’s peers agreed, by jury vote, that that was the just outcome. However, Florida feels differently. When it comes to the death penalty, Florida is one of only two states that has decided that the “right to a trial by jury” does not guarantee that a person will be sentenced to death by a unanimous jury. Instead, in Florida, a person can be sentenced to die even if four people on their jury think they should live. The state requires just eight of twelve jury votes for a death sentence, which not only disproportionately affects people of color, but the very ideals at the heart of the rights of citizenship.

Comprehensive Health of Planned Parenthood Great Plains & Planned Parenthood Great Rivers v. Missouri
The ACLU, ACLU of Missouri, and Planned Parenthood Federation of America are representing Missouri’s two Planned Parenthood providers. Following the passage of Amendment 3, the Right to Reproductive Freedom Initiative, Comprehensive Health of Planned Parenthood Great Plains and Planned Parenthood Great Rivers, filed suit to restore abortion access in the state. The suit seeks to enjoin Missouri’s numerous abortion bans and countless burdensome, medically unnecessary restrictions on abortion that do not improve care or protect patient health. If the requested preliminary relief is granted, Planned Parenthood’s health centers would be able to begin providing abortion in Missouri once more — restoring access to this constitutionally protected health care.

Trabelsi v. Crawford, et al. – Lawsuit Challenging Unlawful Detention and Inhumane Treatment of Acquitted Man
Our client, Nizar Trabelsi, is in the United States against his will. The federal government brought him here from Belgium more than a decade ago and charged him with terrorism-related crimes. At trial, the government’s case failed: a federal jury found Mr. Trabelsi not guilty. But instead of allowing Mr. Trabelsi to return to Belgium after his acquittal, the United States placed him in highly restrictive immigration detention and began an ongoing effort to force him to Tunisia, where he was born and where he will very likely be tortured.
Mr. Trabelsi’s detention violates the Constitution, immigration law, and the extradition treaty between the United States and Belgium. Through this lawsuit, he seeks to return to Belgium, and he demands an immediate improvement of his detention conditions.
