In this amicus brief, the ACLU and its coalition partners urged robust application of the legal standard governing the admissibility of expert testimony and technical evidence, especially in cases involving opaque or proprietary algorithms.

Nevadans, like voters in many states, have chosen to legalize marijuana for medicinal and recreational use. In Nevada, these changes—adopted through citizen ballot initiatives and, in the case of medical marijuana, enshrined in the Nevada Constitution—were intended to ensure that marijuana is regulated much like alcohol and that law enforcement resources are focused on violent crime, not the prosecution of non-violent drug offenses. Despite these legal changes, Nevada’s Board of Pharmacy continues to regulate marijuana as a Schedule I controlled substance for purposes of state law, akin to the Board’s treatment of cocaine and fentanyl. The Board’s scheduling designation for marijuana has enormous implications for criminal defendants in Nevada since state law makes it a felony to possess or engage in certain other activity with respect to a Schedule I controlled substance, as designated by the Board. This case, brought by an individual and organization harmed by the Board’s scheduling designation for marijuana, involves the question whether the designation violates the Nevada Constitution and state statutes. The ACLU of Nevada is counsel in the case, and the ACLU’s State Supreme Court Initiative is co-counsel on appeal. In August 2024, the Court held that Pool and CEIC lack standing to challenge marijuana's designation as a Schedule I substance but recognized that other individuals could appropriately do so in the future. The Court did not reach the merits in reversing the district court’s positive decision.

In September 2023, the ACLU, the ACLU of Colorado, The Boston University Center for Antiracist Research, the law firm Mintz Levin, and other partners filed an amicus brief with the Colorado Supreme Court arguing that mandatory life-without-parole (LWOP) sentences for strict liability felony murder are “cruel and unusual” in violation of the Colorado and U.S. Constitutions. The brief focuses on how these mandatory LWOP sentences drive racial injustice.

The ACLU, along with the Northern and Southern California affiliates and four other organizations, filed an amicus brief in the Ninth Circuit supporting affirmance of a preliminary injunction that prevented the City of Sacramento from clearing homeless encampments during periods of extreme heat.
