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.

We sued elections officials in Arizona to extend the mail ballot “cure” deadline after ballot processing delays threatened to disenfranchise thousands of voters without notice.

On October 31, 2024, just five days before the November 5 General Election, Cobb County announced that it had failed to send more than 3,000 absentee ballots to Cobb County voters who had timely requested them. Many of these voters are at school hundreds of miles away or have disabilities that make it all but impossible to vote in person. The ACLU and co-counsel sued on behalf of affected voters to ensure that they would not be disenfranchised because of the County's administrative error.

The South Carolina Department of Motor Vehicles (SCDMV) has unlawfully denied young, eligible South Carolinians the opportunity to register to vote. Under South Carolina law, individuals who are 17 years old may register to vote and vote in primary elections so long as they (1) will turn 18 on or before the next general election, and (2) otherwise meet the qualifications for voting. An administrative error in the SCDMV's processes, however has stopped the Department from transmitting the proper paperwork to complete all registration information to the South Carolina Elections Commission. As a result, thousands of young voters who did everything right and should have been registered to vote have not been added to the state's voter rolls in the runup to the 2024 general election. ACLU and ACLU of South Carolina sued, asking the court to ensure that these new voters are registered and properly notified in time for them to vote in the November 2024 election.
