Fighting Voter Suppression
Coalition for Open Democracy v. Scanlan
This lawsuit challenges HB 1569, a new law that will make New Hampshire the only state to require every person to produce documentary proof of citizenship when they register to vote for both state and federal elections. It also challenges HB 1569’s elimination a preexisting protection for voters—namely, an affidavit option that allowed voters who faced surprise challenges to their eligibility at the polls to swear to their qualifications and cast a ballot. Accordingly, HB 1569 violates the First and Fourteenth Amendments of the U.S. Constitution by placing substantial burdens on New Hampshirites at all stages of the voting process, and will arbitrarily disenfranchise hundreds, if not thousands of qualified voters.

Fighting Voter Suppression
League of Women Voters of Massachusetts v. Trump
On March 31, 2026, President Trump issued a sweeping Executive Order titled "Ensuring Citizen Verification and Integrity in Federal Elections," seeking once again to seize control of election administration from Congress and the states. The Order directs federal agencies to compile lists of U.S. citizens and transmit them to states before every election, directs the U.S. Postal Service -- an independent agency established by Congress -- to create a list of "approved" mail voters, and instructs USPS to refuse to deliver ballots from voters not on that federally created list. If implemented, the Order would threaten the ability of millions of eligible citizens to cast their ballots, particularly military members, overseas citizens, the elderly, recently naturalized citizens, and voters with disabilities who rely on mail voting.

Fighting Voter Suppression
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.

Fighting Voter Suppression
United States v. Adams
The Trump administration's Department of Justice has taken Kentucky to court in an attempt to obtain sensitive, non-public information from the state's voter registration database — including Social Security numbers, driver's license numbers, dates of birth, and home addresses. This lawsuit is one of nearly three dozen similar actions filed against states across the country, and reporting suggests the underlying goal is to construct an unauthorized federal voter database and use error-prone data-matching tools to target registered voters — including naturalized citizens — for potential removal from the rolls.

Fighting Voter Suppression
League of Women Voters of Ohio v. LaRose
Voting-rights and civil-rights organizations filed a federal lawsuit challenging a new Ohio law that threatens to wrongly strip eligible citizens—particularly naturalized citizens—of their right to vote.
The case arises from Ohio Senate Bill 293 (SB 293), a law that mandates aggressive, automated purges of Ohio’s voter rolls based on flawed citizenship data. Under SB 293, state officials are required to conduct frequent database checks and cancel voter registrations for people flagged as “noncitizens”—often without advance notice or a meaningful opportunity to correct mistakes.
Plaintiffs brought this case to stop a system that places thousands of eligible voters at risk of disenfranchisement and undermines fundamental protections guaranteed by federal law and the U.S. Constitution.

United States v. Matthews
The Department of Justice sued the Illinois Board of Elections, demanding the state produce its full, unredacted voter file, which contains highly sensitive and personal data on every voter in the state. This suit appears to be part of the federal government's efforts to build a national voter database without congressional authorization and to improperly question the validity of state voter rolls.
