Supreme Court allows Trump administration to use federal database to screen voter rolls

# What the court decided On Sept. 25 the U.S. Supreme Court granted a 6-3 emergency stay that allows the Trump administration to use a modified version of the Systematic Alien Verification for Entitlements (SAVE) database to respond to state and local requests about voter eligibility. The stay is temporary and leaves open further litigation in the lower courts.

# How this got to the court The issue began after a 2025 presidential order that expanded DHS access to federal records, including Social Security data, through SAVE. League of Women Voters v. DHS challenged that expansion, arguing it violated the Social Security Act, the Privacy Act and other statutes that limit agency actions.

The administration appealed directly to the Supreme Court, which issued the emergency stay while the case proceeds.

# Legal rationale in the majority opinion

The majority acknowledged a federal law that bars mass purges of voter rolls within three months of an election, and said that moratorium limits how much the stay could affect the upcoming midterms. The opinion added that individualized inquiries, which the government says SAVE is suited for, are still permitted during the restricted period.

# Dissent and concerns Justice Ketanji Brown Jackson wrote the dissent, joined by Justices Elena Kagan and Sonia Sotomayor. The dissent criticized the court for acting without full briefing or oral argument and said the majority focused on government harms while disregarding harms to lawful voters caused or likely to be caused by the modified SAVE system. The dissent characterized the use of equitable powers here as improper.

# Immediate practical effects

# What to watch next

• How the full appeals court handles the merits on remand and whether the injunction will be reinstated or overturned.
• Whether plaintiffs pursue expedited briefing or additional emergency relief before the Supreme Court.
• State and local election officials' use of any lists or responses DHS provides and how those are applied to voter-roll maintenance, especially given the three-month moratorium on mass purges.

This ruling affects the administration's immediate ability to provide federal data to states for voter-verification purposes, while leaving open the larger legal questions about statutory authority and privacy protections.
