Common Cause v. U.S. Department of Justice
The U.S. Department of Justice has launched an unprecedented and unlawful effort to invade the privacy of millions of American voters and threaten their right to vote. It has demanded that every state and the District of Columbia turn over their entire voter database, including Social Security Numbers, political party affiliation, and voter participation history. And at least a dozen states have complied, submitting their voters’ information for federal review. But the Department of Justice has no authority to dictate when a voter registration should be cancelled, and we are suing to stop the federal government’s overreach and ensure that voters’ information remains secure and free from unlawful interference.

League of Women Voters Education Fund v. Trump
On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commission—an agency that Congress specifically established to be bipartisan and independent—to require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.
On behalf of leading voter registration organizations and advocacy organizations, the ACLU and co-counsel filed a lawsuit to block the Executive Order as an unconstitutional power grab.

Weir v. U.S.
The American Civil Liberties Union filed a federal lawsuit in June 2019 against the United States and the head of the U.S. Coast Guard on behalf of four Jamaican fishermen, who were forcibly removed from their fishing boat and detained for over a month at sea on four U.S. Coast Guard ships in patently inhumane conditions.

Comments on Petition of America First Legal for Rulemaking Before the Election Assistance Commission
The ACLU, along with several partner organizations, is opposing a request to the U.S. Election Assistance Commission from the America First Legal Foundation (AFL) for a new rulemaking to consider changing the federal voter registration form to add a requirement for documentary proof of citizenship.
The federal voter registration form was created by the National Voter Registration Act (NVRA), and under federal law almost all states in the country have to accept it as a form of mail voter registration. As intended by the NVRA, the form is a one page, streamlined application that an individual can complete and mail-in without providing any additional documentation. If the rules about the federal form are changed so that additional documentation is required, it is likely that many states would also change their own state voter registration forms to require documentary proof of citizenship.
This change would potentially disenfranchise millions of eligible U.S. citizens.

Bower v. Social Security Administration
Representing itself and two journalists from Lawfare, the American Civil Liberties Union brought a lawsuit to enforce Freedom of Information Act (FOIA) requests made to the Social Security Administration and U.S. Citizenship and Immigration Services regarding changes made to the SAVE program, which has been touted as being used by states in order to remove voters from the registration rolls. While the government made public statements about the SAVE program being updated, the details of those changes, such as the particular programs and databases that have been altered, the ways they have been altered, and the nature and extent of any use and sharing of individuals’ personal information by the federal agencies entrusted with that information, have all been kept secret.

Connell v. CIA – FOIA Lawsuit Seeking Records About CIA “Operational Control” Over a Detention Facility at Guantánamo Bay
The CIA has refused to disclose whether it has records about its operational control over Camp VII, a detention facility at Guantánamo Bay. Given the extensive public record about the CIA’s connection to Camp VII, its refusal to acknowledge that it has responsive records both violates the law and defies common sense. At stake is whether the court will reject the CIA’s version of official secrecy and call out its fiction of deniability or whether it will allow that fiction to stand.
