The Supreme Court Is Letting States Keep Checking Voter Lists for Now

The U.S. Supreme Court is letting states keep using a changed federal system to check voter lists for now.

The action, reported Sept. 25, 2026, pauses a lower-court order that had blocked the changed system while the lawsuit goes on. The order is temporary. It does not decide if the changes are legal. NPR

SAVE stands for Systematic Alien Verification for Entitlements. It is a 40-year-old federal system. It was first built to check the immigration status of noncitizens for public benefits.

DHS changed SAVE by connecting it for the first time to Social Security records that cover most Americans. It also let states check large groups at once, like checking a whole classroom list instead of one student at a time. DHS then asked states to upload their full voter rolls to check U.S. citizenship and whether voters are listed as dead in federal records.

Before, SAVE worked one case at a time. Now states can run full state files through federal databases in big batches.

The League of Women Voters and the Electronic Privacy Information Center sued over the changes about a year ago. In June 2026, U.S. District Judge Sparkle Sooknanan blocked the changed version. She said it broke the Social Security Act, the Privacy Act and the Administrative Procedure Act.

An appeals court panel voted 2-1 to keep that block in place. U.S. Solicitor General D. John Sauer then asked the Supreme Court in September 2026 to let the system run during the appeal.

The Solicitor General's filing said the new SAVE has checked more than 65 million voters in 26 states since May 2025. It flagged 28,635 voters as possible noncitizens. NPR

The system has wrongly flagged some eligible voters as possible noncitizens. That error rate is central to the fight. DHS rules require users to contact the voter and ask for proof of U.S. citizenship before further action, and agency filings state SAVE does not itself decide citizenship.

DHS said SAVE is a secure and reliable way for states to check citizenship or immigration status of people registering to vote. The department also told states they must use SAVE or another approved government system to check citizenship. SAVE charged fees to help federal, state, tribal and local agencies confirm citizenship and immigration status, though DHS and U.S. Citizenship and Immigration Services moved to end those fees.

The broader context here is how voter lists are kept up to date. A big batch check can flag many names fast. Local officials must still follow up, get proof from the voter, and follow federal notice and timing rules before removing anyone. So far there is a large gap between total checks and flags, and between flags and proven ineligibility.

There is also recent history for quick, temporary orders. In October 2024, the Supreme Court paused a court order that had stopped Virginia's program for removing noncitizens from its voter rolls. That move also kept a state effort going while the case continued without deciding who was right.

The legal case is still open. The district court said the Social Security link and bulk checks broke limits on sharing and reuse of that data and did not meet the law's need for clear agency reasons. The government said the stay was needed to avoid disrupting checks in states using the system. The challengers said continued use risks privacy harm and wrongly questioning eligible voters.

The stay keeps the changed system open to states that want to use it. The appeal will decide if DHS can keep the Social Security link, the bulk checks, and the voter-roll uploads as they are.
