The American Civil Liberties Union, ACLU of Montana, Native American Rights Fund (NARF), and the Harvard Election Law Clinic challenged two Montana laws that hinder Native American participation in the state’s electoral process — HB 530, which prohibited paid third-party ballot collection; and HB 176, which repealed Election Day voter registration (EDR) in Montana. Together, these laws violate a number of provisions in the Montana Constitution: the right to vote, equal protection, free speech, and due process.

In November 2022, thousands of Pennsylvania voters were denied the right to vote based on a meaningless paperwork error. They filled out their mail ballots, signed the form on the outer return envelope, and returned their ballots on time. Yet their ballots were not counted, because they either forgot to write the date on their return envelope, or they accidentally wrote the wrong date. The Civil Rights Act prohibits states from disenfranchising voters based on immaterial paperwork error, and we're fighting to make sure that every vote counts

The ACLU and partner organizations have sought to intervene to represent the rights of voters and voting-rights organizations in a case seeking to unlawfully purge the Texas voter rolls and block certification of the results of the 2024 election.

Civil rights groups filed a federal lawsuit on March 29, 2021, against Georgia’s sweeping law that makes it much harder for all Georgians to vote, particularly voters of color and voters with disabilities. This law spans all aspects of Georgia’s voting process, including imposing a criminal ban on providing food and water to voters waiting in line, limiting dropbox access and ballot return assistance, rejecting absentee ballots for forgetting to add a birthdate to an envelope or for failing to provide more restrictive identifying information or photo ID copies along with absentee ballots. Premised on low voter confidence and born out of the Big Lie about the 2020 election, this law targets methods of voting disproportionately used more and more by Black voters and others voters of color just as they began to exercise greater political power.
