US Supreme Court allows use of federal database for voter citizenship verification

The US Supreme Court has ruled 6-3 in favor of the Trump administration, allowing the use of an expanded federal database to verify the citizenship status of registered voters ahead of the November midterm elections. This decision suspends a lower court injunction that had previously restricted the use of the Systematic Alien Verification for Entitlements (SAVE) system, which is managed by the Department of Homeland Security. The system enables state authorities to cross-reference voter information, including social security numbers, against federal records to confirm citizenship and legal voting eligibility.

The administration maintains that this tool is essential for identifying non-citizens on electoral rolls. Conversely, civil and voting rights organizations have raised concerns regarding potential privacy violations and the risk of erroneous purging of eligible voters from registration lists. The ruling reverses a June decision by a federal court, which had concluded that the government’s actions infringed upon citizens' privacy rights.

This legal development follows a March 2025 executive order issued by President Donald Trump, which mandated stricter scrutiny of electoral rolls and aimed to restrict mail-in voting. While the court’s decision addresses voter verification, observers note it is considered less impactful on the midterm election outcome than ongoing litigation regarding mail-in ballot procedures.
