United States v. Alaska
Representing two Alaska voters, the League of Women Voters of Alaska, and Common Cause, the American Civil Liberties Union and ACLU of Alaska moved to intervene in United States v. Alaska, a frivolous lawsuit seeking to prevent from the State of Alaska from certifying its election results if the incumbent U.S. Senator does not win the election. The lawless suit asserts a single claim based on the purpose language of the National Voter Registration Act (NVRA), that has no basis in any case, legal principle, or arguably tenable reading of the NVRA.
We are seeking dismissal of this suit that aims to deprive Alaskans of their right to vote and right to representation.

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 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.

Racial Justice
Allen v. Milligan
Whether Alabama’s congressional districts violate Section 2 of the Voting Rights Act because they discriminate against Black voters. We succeeded in winning a new map for 2024 elections which, for the first time, has two congressional district that provide Black voters a fair opportunity to elect candidates of their choosing despite multiple attempts by Alabama to stop us at the Supreme Court. Despite this win, Alabama is still defending its discriminatory map, and a trial was held in February 2025 to determine the map for the rest of the decade.
In May 2025, a federal court ruled that Alabama’s 2023 congressional map both violates Section 2 of the Voting Rights Act and was enacted by the Alabama Legislature with racially discriminatory intent.

White v. Mississippi State Board of Elections
District lines used to elect Mississippi’s Supreme Court have gone unchanged for more than 35 years. We’re suing because the current lines crack the Mississippi Delta and dilute the voting strength of Black Mississippians in state Supreme Court elections, in violation of the Voting Rights Act.

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.

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.

Issa v. Weber
Congressman Darrell Issa sued to prevent California from counting mail ballots postmarked by election day and received within the following seven days, consistent with California law. If successful, literally hundreds of thousands of Californians will be disenfranchised at each election. The ACLU and its three California affiliates have sought to intervene in the case on behalf of the League of Women Voters of California to ensure that California voters are able to have their ballots counted consistent with state procedures.

Watson v. Republican National Committee (Amicus)
In 2020, in a nearly unanimous bipartisan vote, Mississippi joined eighteen other states in accepting mail ballots postmarked by Election Day that arrived after Election Day (in Mississippi’s case, up to five business days). This lawsuit by partisan actors seeks to disenfranchise these voters whose ballot is mailed by Election Day but—through no fault of their own—does not arrive until afterwards. In Mississippi, this harm will fall disproportionately on voters with disabilities, older voters, and other communities that rely upon absentee voting. Twisting the words and meaning of Congress, the RNC argues that three longstanding federal laws that set a uniform election day for federal races require that ballot may only be counted if they are received by election officials by Election Day. If accepted, this radical argument would not only disenfranchise thousands upon thousands of voters in Mississippi and thirty other states, but also upend election administration in every state.
