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. On November 20, 2025, the court held the deployment of the D.C. National Guard was unlawful in the absence of a request from the D.C. government because it is beyond the President's power under Title 49 of the D.C. Code, enacted by Congress. The court further held that the deployment of other states' National Guards to D.C. was not justified by the provision of federal law that the President invoked because it is limited to operations authorized by those states' laws. Accordingly, the court granted a preliminary injunction but stayed it for 21 days to enable the government to appeal.

In this case, a Republican congressman from Illinois sued to challenge a state ballot counting deadline. His case was dismissed for lack of "standing" — meaning a personal stake in the outcome that is a prerequisite to filing a case in federal court. The lower courts ruled that it wasn't enough that the plaintiff's campaign had to spend money to cope with the election rule that he was challenging. When the Supreme Court agreed to review the case, we saw an important opportunity. Although we vigorously disagree with the congressman's position on the merits, it's vitally important that courts remain open to plaintiffs challenging voting rules that may disadvantage them. We have represented the League of Women Voters in such cases, and the government always seeks to challenge their standing, making the same types of arguments that kicked the plaintiff out of court here. Together with the League of Women Voters, the National ACLU, the ACLU of Illinois, and the Rutherford Institute, we filed an amicus brief in July 2025 to urge the Supreme Court to hold to its previous rulings permitting plaintiffs to sue based on economic harms to their organization. As we summarize our point in the brief: "political actors, candidates, and civic organizations may have standing to challenge electoral laws and regulations that affect their activities, force them to divert resources, and thus cause them concrete and tangible harms." Preserving access to the federal courts is fundamental to the defense of civil liberties and civil rights, because courts cannot vindicate these rights if they lack the power to hear the case in the first place. In January 2026, the Supreme Court ruled that the congressman had standing, though not for the reason we urged. Instead, the Court reasoned that candidates for election have a special interest in the fairness of election procedures, and this interest gives them standing. Concurring, Justices Barrett and Kagan agreed with our the economic-cost approach of our amicus brief. Regardless, expanding standing to test the fairness of election procedures will help ensure that legitimate challenges are not shut out of court.

This brief argues that the Freedom of Information Act does authorize private lawsuits to enforce the publication provision, and that the courts do have authority to order agencies to comply with it.

Ebosele Oboh was renovating his house without having obtained the necessary permits. The Department of Buildings issued him a fine for the violation, then doubled the fine as a penalty for not responding to the first. This amicus brief argues that the excessive penalty violates the 8th Amendment.

In 1969, seventeen-year-old Bruce Taylor enlisted in the army and volunteered for a secret weapons testing program at the Edgewood Arsenal in Maryland, where he was used as a human guinea pig in experiments with chemical weapons. As a result, he has suffered from a lifelong health condition.
