Court Cases

On August 11, 2025, President Trump invoked a section of the Home Rule Act permitting him to demand services from the D.C. police for federal purposes, and began flooding the District with federal agents, D.C. National Guard, and National Guard from other states. With a month, the D.C. government sued Trump twice — first to block him from taking over the D.C. Metropolitan Police Department entirely (a suit that induced Trump to back down from that attempt) and then to challenge the deployment of the National Guard. The first case proceeded too quickly for us to file a brief. In the second (both are called District of Columbia v. Trump), we filed an amicus brief supporting the District's lawsuit. Together with our co-counsel Washington Lawyers Committee, and joined by a broad coalition of D.C. nonprofits devoted to serving D.C. residents and fighting for D.C. autonomy (Amica Center for Immigrant Rights, Bread for the City, Children’s Law Center, DC Appleseed Center for Law & Justice, Disability Rights DC, Legal Aid DC, School Justice Project, Tzedek DC, and Washington Legal Clinic for the Homeless), we explained how this most recent attempt to impose on D.C. a law enforcement presence not democratically accountable to the people of D.C. is part of a long history, stretching back 200 years to the founding of the District and often tinged with implicit or explicit racism, of denying D.C. residents full self-governance. Although every other American city and state can take this basic element of representative democracy as a given, for D.C., it have been elusive and, even when obtained, only tenuously held. Setting loose American troops—locally unaccountable and not trained for domestic law enforcement—to police the streets of D.C. neighborhoods on the thin pretext of an “emergency,” is anathema to principles of democratic accountability and our longstanding norm of civilian, not military policing. Additionally, we explain how a locally unaccountable law enforcement presence is likely to be less trusted by the community and therefore less effective — thus showing that Trump's move will make D.C. less safe, not more.

This case, brought by a class of people who are or will be on parole or supervised release in Washington, D.C., challenges the failure of the federal government’s post-conviction supervision system to accommodate individuals with disabilities as required by federal law.

In this case, we argue that WMATA’s advertising guidelines violate the First Amendment, which prohibits government agencies from discriminating against private speech based on its viewpoint or from applying rules that so vague they can’t be applied consistently.

In 2015, police officers shot tear gas at two legal observers with bright green "Legal Observer" hats. The court ruled that words printed on clothing are not entitled to First Amendment protections. Together with the National ACLU and the ACLU of Missouri, we petitioned SCOTUS to review the case.

The lawsuit, filed as a class action, primarily seeks a court order to prohibit DOC officials from imposing requirements on Jewish people in their custody to provide external verification of their religion as a condition for approving their kosher meal requests.

When people in D.C. call 911 for a mental health emergency, it’s generally a Metropolitan Police Department (MPD) officer who responds. The District’s reliance on police as its default first responders for mental health emergencies is not only unfair and unsafe but also unlawful.
