A federal appeals court blocked President Trump’s executive order on mail-in voting from taking effect across 23 states and the District of Columbia on July 25, 2026. The ruling, a 2-1 decision by the Boston-based 1st U.S. Circuit Court of Appeals, keeps in place an injunction secured by Democratic-led states. The administration has signaled it may escalate to the U.S. Supreme Court.
The executive order at the center of the case would restructure how mail-in ballots are processed and delivered nationwide. With every House seat and a decisive share of Senate seats on the ballot in November, the legal timeline is compressing fast.
Multiple federal judges have now ruled on the constitutional question, and the answer has not been favorable to the White House.
What Trump’s Executive Order Actually Required
On March 31, President Trump signed Executive Order 14399, titled “Ensuring Citizenship Verification and Integrity in Federal Elections.” The appeals court ruling addressed an order that moved on several fronts simultaneously, each aimed at restructuring how mail-in ballots are processed and delivered across the country.
The order directs the Department of Homeland Security to compile lists of confirmed U.S. citizens eligible to vote and provide them to states, instructs the U.S. Postal Service to establish new standards for mail-in ballots, and directs the Justice Department to prioritize investigations into state and local election officials who issue federal ballots to people deemed ineligible to vote.
The order also reached into the physical design of ballots. It directed the USPS to control states’ mail ballot designs by ensuring they have unique Intelligent Mail barcodes and logos on the envelopes. The postal service was expected to impose these changes even for states that had already purchased mail-in ballot envelopes for the year, creating immediate financial and logistical complications for election administrators who had already planned and budgeted for the November cycle.
The order directed the Department of Justice to investigate officials who mail ballots to people who are “not eligible” to vote, a provision that put state election workers in the crosshairs of potential federal prosecution simply for following their own states’ laws. Trump, in the Oval Office after signing, said: “We want to have honest voting in our country, because if you don’t have honest voting, you can’t have, really a nation if you want to know the truth.” He had himself recently voted by mail in Florida.
The Constitutional Problem States Immediately Identified
The legal challenges landed fast. The Constitution vests the administration of elections in the states, though Congress can pass laws pertaining to elections. The executive branch does not have an official role in changing election laws or carrying out elections.
The Constitution’s Elections Clause says that the rules for running federal elections “shall be prescribed in each State by the Legislature thereof,” except that “Congress may at any time by Law make or alter such Regulations.” Two actors have authority over federal election rules: state legislatures and Congress. The president is not among them.
The order also violated federal statutes by attempting to direct the actions and policy determinations of USPS, which is an independent agency.
As for the fraud justification Trump repeatedly cited, a November 2025 Brookings Institution analysis examined hundreds of mail voting cases cross-referenced with election statutes across the 2016, 2018, 2020, and 2022 general elections and found the total mail voting fraud rate was 0.000043%, roughly four confirmed cases per 10 million mail votes cast.
What the Lower Court Ruled in June
U.S. District Judge Indira Talwani, based in Boston, ruled first. The 1st U.S. Circuit Court of Appeals rejected the administration’s request to lift an injunction several Democratic-led states had secured on June 25 from Talwani, who concluded that key parts of the president’s order were unconstitutional.
Talwani said Trump had no authority to have the DHS compile voter citizenship data, and that the USPS equally had no authority to follow his orders about mail-in voting. She also took seriously the financial burden the order would impose on states that were already midway through their election preparations. Her ruling pointed out that complying with the executive order’s unusual demands would mean states would be financially burdened for making changes to their mail ballot envelopes.
A federal judge in Washington, D.C., rejected a related effort by Democrats to block Trump’s order on similar grounds. That split between the two courts created a patchwork situation where the order remained blocked in some jurisdictions but not others, and it gave the administration some basis to push back at the appellate level.
How the Appeals Court Ruled, and What the Dissent Argued
The three-judge panel ruled 2-1 against the Trump administration’s motion. One judge, Joshua D. Dunlap, a Trump appointee, dissented in part.
The Justice Department had argued the lawsuit was premature because government agencies had not yet finalized policies to implement Trump’s directive. The appeals court rejected that argument, writing that the order “lays out a clear set of rapidly approaching deadlines by which states must coordinate with federal officials and comply with new voting procedures” ahead of the September and November elections, and that “the Plaintiff States have no practical choice but to respond to the order now.”
The panel also found a credible threat of enforcement. Reading the executive order as a whole, it said the DOJ’s directives to prioritize investigations and prosecutions of election officials created an imminent enough risk to support the states’ standing to sue ahead of the 2026 elections.
Judge Dunlap wrote a partial dissent, arguing that the states likely lack standing to challenge the DHS citizenship-list provision because it merely provides information to states and does not itself require them to take any action. He would have allowed that specific portion of the order to move forward, even while agreeing with the broader ruling on the USPS provisions.
What Happens Next, and Why the Supreme Court Looms
The July 25 ruling does not resolve the underlying legal challenge but leaves Talwani’s injunction in place while the appeal proceeds. A full hearing is scheduled for August. The administration has already signaled it won’t wait quietly for that.
The Justice Department warned that absent a ruling in its favor from the 1st Circuit, it may be forced to ask the U.S. Supreme Court to intervene. Given that the administration has already indicated willingness to escalate, an emergency application in the weeks ahead of November is a plausible, perhaps likely, next step.
The circuit split between the 1st Circuit and the D.C. Circuit adds another layer. The 1st Circuit reached a different result than the D.C. Circuit earlier this month. The D.C. Circuit allowed USPS’s proposed election-mail rule to move forward, though the panel noted it confronted different legal issues with different plaintiffs. A disagreement between federal appeals courts on the same underlying executive order is precisely the kind of conflict that the Supreme Court tends to take up.
Trump has also made winning congressional approval of the SAVE America Act a priority, which would accomplish through legislation some of what the executive order attempted through executive authority. During the Senate’s floor debate on the SAVE America Act, allies of President Trump filed an amendment to satisfy his demands for the legislation to also significantly restrict Americans’ ability to vote by mail.
Several other legal challenges are still pending against the president’s directives, including suits brought by voting rights groups and party organizations. Democracy Docket has reported on the 1st Circuit ruling blocking the order across 23 states and Washington, D.C. The Trump mail-in voting court battle is running on multiple tracks at once, with the 1st Circuit ruling being the most significant single development so far, but far from the last word.

Where This Actually Lands
The Constitution is unusually specific about who gets to run federal elections, and it does not include the executive branch on that list. Every court that has ruled on these provisions in any substantive way, including Judge Talwani, the D.C. Circuit judge who ruled against Democrats on separate grounds, and now the 1st Circuit majority, has found the same thing: a president issuing orders about how states design ballot envelopes, whom the postal service delivers ballots to, and which federal agents investigate local election workers is doing something the Constitution doesn’t authorize.
That’s separate from the policy debate. Plenty of Americans, across party lines, have views about whether mail-in voting should be harder or easier to access. But the legal question isn’t about those views. It’s about who in the federal system has the authority to act on them.
A Supreme Court that decided to take up this question before November would be doing so under significant political pressure and with very little time. Whether it rewrites the outcome the 1st Circuit just handed down is the one question no lower court can answer, and the one the November elections may not be patient enough to wait for.
