Supreme Court sides with Trump administration on mail voting restrictions ahead of midterms

The Supreme Court sided with the Trump administration Monday in a case over President Donald Trump’s executive order restricting mail-in voting, though it remains unclear how much can be implemented before the fast-approaching midterm elections.

The decision leaves room for additional court challenges that could further slow Trump’s order, and other similar cases have already been filed. The U.S. Postal Service laid out how it would implement the order last week, but time is running short to impose major changes with some states beginning to send mail ballots to voters in just a few weeks.

The Supreme Court’s conservative majority didn’t decide the legality of Trump’s order, instead ruling that states who sued did not have the legal right to challenge it.

“The Court’s disposition of this application does not mean that any measure taken by the Government to implement the Order will necessarily be lawful. On that score, time will tell,” the majority wrote in an unsigned order.

The three liberal-leaning justices publicly dissented, with Justice Ketanji Brown Jackson writing that the rule “lets another shoe drop in the Kafkaesque nightmare that our precedents have been steadily creating for certain plaintiffs who seek to bring election-related challenges.”

New York Attorney General Letitia James foreshadowed more legal wrangling, calling the decision a “painful setback” but vowing it would “not be the final word.”

The court’s order opens a path for the administration to begin action to restrict mail voting, but it also could lead to a bevy of potential further litigation that could freeze the federal government again, all starting 10 days before the first mail ballots in the nation are scheduled to be sent to overseas and military voters from North Carolina.

“This is just the first inning of a very fast nine-inning game,” said Derek Muller, a law professor at Notre Dame University.

Trump fights mail-in voting despite its growing popularity

Mail balloting has long been a favorite target for Trump, who has claimed that it breeds fraud despite strong evidence to the contrary and his own use of the voting method.

Trump’s executive order, signed in March, calls on his administration to create lists of eligible voters and orders the U.S. Postal Service to deliver mail ballots only to people on those lists. New requirements released Friday would forbid the Postal Service from sending mail ballots from any state that does not comply with Trump’s order.

Democratic officials in 23 states and the District of Columbia sued to block the order. They argued that the Constitution gives states and Congress the power to run elections, and Trump’s changes could lead to chaos and partisan abuse.

“The consequences of allowing such transformative changes to take effect so close to this fall’s elections would be extreme,” attorneys for the states wrote. Dozens of state and local election officials weighed in, asking the justices to leave the order frozen while election preparations are already underway.

A judge in Massachusetts blocked the plan for the midterm elections in those states. An appeals court upheld her decision. She later granted a second order blocking it nationwide, another remaining stumbling block for Trump administration.

The Justice Department appealed to the Supreme Court on procedural grounds in late July, arguing that the states sued too soon. They also pointed to another ruling out of Washington, where a judge allowed Trump’s order to proceed. An appeals court backed that decision, while still leaving room for future court action if the changes are implemented.

Federal attorneys argued that the Massachusetts order “blocks the government’s ability to finalize and implement the President’s proposed policies to promote election integrity for the upcoming federal elections in November.”

A dozen Republican-leaning states supported the federal government in their own appeal before the high court, saying states would have input on the final voter lists.

The Supreme Court has previously ruled against Trump-backed arguments on mail-in ballots, finding in June that states can count ballots that arrive after Election Day. That case was decided after full briefing and arguments, rather than on the court’s emergency docket.

Trump has blamed mail voting — without credible evidence — for his loss to Democrat Joe Biden in 2020. He has promoted the proposed changes in his executive order as safeguards to keep non-U.S. citizens from voting.

He’s also repeatedly pressed for the passage of the legislation that requires proof of citizenship to vote. Noncitizen voting has been shown to be rare, and is a felony that can be punishable by deportation.

Using mail ballots has become increasingly popular with voters of both parties, with about 30% of all ballots cast that way during the 2024 presidential election, according to federal data. The process also is secure. A 2025 Brookings Institution study found only about four cases of fraud out of every 10 million mail ballots cast.

David Becker, a former justice department lawyer who co-wrote a book debunking Trump’s 2020 election lies, said the high court created “pure chaos leading up to the midterm elections, waiting weeks after an administration filing, and just days before mail ballots go out, to completely rewrite the rules.”

Becker added he expects the Trump order to ultimately be blocked in the new legal process the court decision effectively greenlit.
