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.

Students for Justice in Palestine at the University of Florida v. Raymond Rodrigues
The University of Florida chapter of Students for Justice in Palestine filed a lawsuit on November 16, 2023, challenging the Chancellor of the State University System of Florida’s order to state universities to deactivate the student group. This order threatens the students’ constitutionally-protected right to free speech and association in violation of the First Amendment. The ACLU and its partners are seeking a preliminary injunction that would bar the Chancellor and the University of Florida from deactivating the UF SJP.

FBI v. Fazaga
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.

ACLU v. NSA – FOIA Lawsuit Seeking Records of Government Use of Section 702 of FISA
Section 702 of the Foreign Intelligence Surveillance Act permits warrantless surveillance of Americans’ international communications, and the government has used that authority to seize and search the personal communications of Americans and others on an immense scale. In September 2016, the ACLU submitted a Freedom of Information Act request to several government agencies seeking basic information about how the government conducts surveillance under Section 702. In November 2016, we filed a lawsuit to enforce the request in the U.S. District Court for the Southern District of New York.

ACLU v. DOJ - FOIA Case for Records Relating to Killing of Three U.S. Citizens
In October 2011, the ACLU submitted a Freedom of Information Act (FOIA) request seeking information about the killings of three U.S. citizens in Yemen: Anwar al-Aulaqi; his 16-year-old son, Abdulrahman al-Aulaqi; and Samir Kahn. Over five years of litigation, this case was appealed to the Second Circuit three times. The government acknowledged it had killed the three Americans, and was forced to describe targeted-killing program documents in its possession. The ACLU won an important victory in securing the release of a memorandum in which the government set out its legal justification for killing Anwar al-Aulaqi in June 2014. In December 2016, the Second Circuit ruled that no other documents must be disclosed, concluding this litigation. The ACLU continues to seek additional details about the targeted killing program’s rules and consequences through other FOIA requests and cases.
