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.

Sarkar v. Doe - PubPeer Subpoena Challenge
The ACLU filed a motion in Michigan state court challenging the constitutionality of a subpoena issued to the website PubPeer demanding that it turn over the identities of anonymous commenters. In March 2015, the trial judge ruled that PubPeer had to unmask one – but only one – of the commenters. Both PubPeer and the researcher appealed, and the ruling was upheld in December 2016.
