A federal appeals court ⁠panel ⁠rejected the Trump ⁠administration’s bid to lift a ban on using a ​federal immigration database to check the accuracy of citizenship records ‌on states’ voter rolls.

In a ‌2-1 ruling on Friday, the U.S. Court of Appeals ⁠for the ⁠District of Columbia declined to lift a lower court’s ​ban on using the Homeland Security Department’s Systematic Alien Verification for Entitlements database. The earlier ruling determined that the government cannot ​use the system ahead of the November 3 midterm elections, ⁠in ⁠which Trump’s Republicans will ⁠be ​defending narrow majorities in both chambers of Congress.

Chief Judge Sri Srinivasan ​and U.S. Circuit ⁠Judge Robert Wilkins, both appointed to the appeals court by President Barack Obama, upheld the lower court decision that the SAVE system violates the Social Security Act as ⁠it shares millions of Americans’ private information. The appeals court judges also ⁠noted concerns around the potential for inaccurate citizen information that could lead to people having to prove citizenship to remain registered voters, and in some cases could even lead to voter registration being canceled.
