Supreme Court Allows States to Use SAVE Database for Voter Citizenship Verification

The U.S. Supreme Court ruled on September 25, 2026, that states may utilize the federal SAVE database to verify voter citizenship. This decision reverses previous lower court rulings which found the database to be inaccurate and potentially disenfranchising eligible voters. In the majority opinion, the Court stated, "the Federal Government has an obligation to respond to requests from state and local election officials seeking to verify the citizenship of voters." The ruling noted that the District Court's order hindered the Federal Government's ability to assist state and local agencies in administering midterm elections. The SAVE database, initially designed by the Department of Homeland Security to assess benefit eligibility for immigrants, was repurposed under the Trump administration for voter citizenship screening. Critics argue that the database is outdated and often inaccurate, posing risks of wrongfully removing eligible voters from registration rolls. Voting rights organizations, including the League of Women Voters and the Electronic Privacy Information Center, filed a lawsuit last year, claiming that using SAVE data alongside Social Security records violated confidentiality laws. While the Supreme Court's ruling permits states to use the database, its adoption is uncertain. Some conservative states have previously utilized SAVE, claiming it aids in maintaining voter rolls, while many states have resisted federal efforts to implement citizenship verification systems. Election experts suggest the ruling's impact on the 2026 elections may be limited due to federal laws that prevent changes to voter registration within 90 days of an election. David Becker, executive director of the Center for Election Innovation and Research, noted that while the SAVE system could assist states in keeping voter lists accurate, the Department of Homeland Security acknowledges the data's imperfections. Three justices – Ketanji Brown Jackson, Sonia Sotomayor, and Elena Kagan – dissented, expressing concerns about the lack of full briefing or oral argument prior to the Court's decision. They argued that the majority's ruling overlooked established laws and procedures governing federal system modifications. The dissenters criticized the majority for treating the Illegal Immigration Reform and Immigrant Responsibility Act as overriding privacy laws related to the sharing of citizenship information with DHS, labeling this assessment as implausible.
