Issa v. Weber
Case Summary
LWV California moved to intervene to defend voters and its members after a sitting congressman filed a lawsuit to shorten California’s mail ballot receipt deadline and to block counting mailed ballots received after Election Day. California currently allows mail ballots to count if received by elections officials up to seven days after Election Day, so long as they were postmarked by Election Day. Congressman Darrell Issa had filed a federal lawsuit, asserting federal law preempted this deadline and mandated all mail ballots be received by Election Day to count.
California allows mail ballots to count if they are postmarked by Election Day and are received by election officials up to seven days after Election Day. Currently, fourteen states and Washington D.C. allow mail ballots to be counted even if they arrive after Election Day if certain conditions are met.
On March 13, 2025, Republican Congressman Darrell Issa filed a lawsuit in the United States District Court for the Southern District of California alleging the state’s mail ballot receipt deadline was preempted by the federal law setting a single national election day for federal offices. The congressman argued that accepting mail ballots after Election Day, even when they were postmarked by that day, constituted extending the election beyond what was permitted by federal law, which prescribed a specific election day for congressional elections, but did not mandate an election day deadline for receiving postmarked mail ballots. Under Issa's argument, because Congress has the power to set a time for congressional elections, the state law conflicted with the federal statute doing so, and was therefore invalid. Rep. Issa requested that the federal court strike down California’s current ballot receipt deadline and require mail ballots to arrive by Election Day to be counted.
On April 17, 2025, the League of Women Voters of California (LWV California) moved to intervene to defend the state’s mail ballot receipt deadline. LWV California argued that accepting the plaintiff’s argument would potentially disenfranchise thousands of voters, who cast their votes by Election Day but whose votes might not be counted due to delays in mail service, among other voting barriers. It would also severely impact the League’s mission to educate voters and increase voter turnout and force voters to mail their ballots well in advance of Election Day or risk that their vote will not be counted.
The League was represented in this matter by the ACLU, ACLU Southern California, ACLU of Northern California, and the ACLU of San Diego and Imperial Counties.
