The ACLU National Prison Project and partner civil rights attorneys filed a federal class-action lawsuit to prevent the transfer of children in the custody of Louisiana’s Office of Juvenile Justice to the Louisiana State Penitentiary, commonly known as Angola Prison.

The ACLU is challenging the constitutionality of the NSA’s mass interception and searching of Americans’ international Internet communications. At issue is the NSA’s “Upstream” surveillance, through which the U.S. government systematically monitors private emails, messages, and other data flowing into and out of the country on the Internet’s central arteries. The ACLU’s lawsuit was brought on behalf of the Wikimedia Foundation and eight legal, human rights, and media organizations, which together engage in trillions of sensitive communications and have been harmed by Upstream surveillance.

UPDATE: U.S. District Judge Roslyn O. Silver found on June 30, 2022, that the Arizona Department of Corrections, Rehabilitation, and Reentry (ADCRR) systematically violates the constitutional rights of persons incarcerated in the state’s prisons by failing to provide them minimally adequate medical and mental health care, and by subjecting them to harsh and deprived conditions in solitary confinement units.

The case concerns the constitutionality of a Mississippi law prohibiting abortions after the fifteenth week of pregnancy. The state used the case as a vehicle to ask the Supreme Court to take away the federal constitutional right to abortion it first recognized 50 years before in Roe v. Wade. On June 24, 2022, the Supreme Court of the United States accepted the state’s invitation and overturned Roe eliminating the federal constitutional right to abortion.

In a case scheduled to be argued before the U.S. Supreme Court on November 8, 2021, three Muslim Americans are challenging the FBI’s secret spying on them and their communities based on their religion, in violation of the Constitution and federal law. In what will likely be a landmark case, the plaintiffs — Yassir Fazaga, Ali Uddin Malik, and Yasser Abdelrahim — insist that the FBI cannot escape accountability for violating their religious freedom by invoking “state secrets.” The plaintiffs are represented by the Center for Immigration Law and Policy at UCLA School of Law, the ACLU of Southern California, the American Civil Liberties Union, the Council for American Islamic Relations, and the law firm of Hadsell Stormer Renick & Dai.

In 2018, the American Civil Liberties Union and the ACLU of Kentucky filed a suit on behalf of Kentucky abortion providers and their patients challenging a state law banning physicians from providing a safe and medically proven abortion method called dilation and evacuation, or “D&E.” If it were to take effect, this law would prevent many patients from being able to obtain an abortion altogether. After two courts held that the law is unconstitutional, the Supreme Court ruled in March 2022 that Kentucky Attorney General Cameron can continue his pursuit to push abortion out of reach by intervening in the underlying challenge to an abortion ban, which is proceeding in a lower court.

Whether the Immigration and Nationality Act requires a bond hearing for immigrants subject to prolonged detention while seeking protection in the U.S. from persecution or torture.

The American Civil Liberties Union, the ACLU of Texas, and coalition partners filed a federal lawsuit on behalf of abortion providers and funds on July 13, 2021, challenging S.B. 8, a Texas law allowing private citizens to enforce a ban on abortion as early as six weeks in pregnancy—before many know they are pregnant. The ACLU’s challenge made its way to the U.S. Supreme Court three times in as many months. After hearing oral arguments in the case, the Court issued a decision on December 10, 2021, that ended the most promising pathways to blocking the ban. The Supreme Court’s decision makes it more difficult to obtain adequate relief from the courts and gives states the green light to ban abortion using bounty-hunting schemes. Texas’ abortion ban will remain in effect until relief can be secured from a court.

The American Civil Liberties Union, Southern Poverty Law Center, and Center for Gender & Refugee Studies filed a federal lawsuit challenging the Trump administration’s new policy forcing asylum seekers to return to Mexico and remain there while their cases are considered.
