American Civil Liberties Union of Colorado

The ACLU of Colorado also operates a foundation arm, the American Civil Liberties Union Foundation of Colorado, which handles educational and research activities. ⁴

Background

The ACLU of Colorado was incorporated in 1952 as an affiliate of the national American Civil Liberties Union, and the group states that earlier efforts to coordinate civil liberties defense in the state date back to the 1930s, following the creation of the national ACLU in 1920. The group established its headquarters in Denver and expanded its operations over subsequent decades, adding litigation, lobbying, and public education components. By the early 2020s, the organization reported a combined budget exceeding $4 million and membership of over 40,000. ^{5 6 7}

The ACLU of Colorado has litigated against U.S. Immigration and Customs Enforcement (ICE) policies, including challenges to bond denials and warrantless arrests of immigrants. The group has also sued school districts over the removal of school library books and alleged restrictions on employee speech. On criminal justice, the group has investigated municipal court practices and advocated policies to reduce incarceration. The organization has opposed law enforcement’s adoption of artificial intelligence tools and pushed for new policies on the handling of voter data. It has also secured settlements related to prison censorship policies and police surveillance files. ^{8 5}
