A federal judge in Boston has permanently struck down the core provisions of President Trump's executive order on election integrity, ruling that the president lacks constitutional authority to require documentary proof of citizenship on federal voter registration forms. The decision converts a preliminary injunction issued roughly a year ago into a permanent ban, closing the door on the administration's attempt to impose the requirement through executive action alone.
U.S. District Judge Denise Casper, an Obama appointee who serves as chief judge for the District of Massachusetts, found that the order violated the separation of powers. Her ruling blocks not only the citizenship-proof mandate but also provisions that would have restricted late-arriving mail ballots and withheld federal election grants from states that refused to comply.
Trump signed the executive order, titled "Preserving and Protecting the Integrity of American Elections," on March 25, 2025. It directed the Election Assistance Commission to add a documentary proof-of-citizenship requirement to the federal voter registration form. It also targeted military and overseas voter rules and threatened to cut federal election funding to states that did not fall in line.
Nineteen Democratic-led states sued the administration, arguing that the president had no unilateral power to rewrite election rules that Congress and the states control under the Constitution. Judge Casper agreed.
In her ruling, as reported by the Washington Examiner, Casper wrote that the central question was straightforward:
"The issue here is whether the President can require documentary proof of citizenship where the authority for election requirements is in the hands of Congress."
She answered that question with a permanent injunction, declaring the challenged sections of the order "unconstitutional and void."
Casper is not the first federal judge to reject the executive order. In April 2025, Judge Colleen Kollar-Kotelly in Washington, D.C., partially blocked the same provisions. But Casper's ruling goes further by converting preliminary relief into a permanent bar, AP News reported.
The pattern of federal courts checking executive overreach on election rules echoes other recent clashes between the judiciary and the White House. In one case, the DOJ moved to disqualify a judge in a Georgia voter rolls lawsuit, pointing to misconduct allegations in an effort to reshape the legal battlefield.
Casper grounded her decision squarely in constitutional text. She wrote that the Constitution "does not grant the President any specific powers over elections," a line she repeated in multiple sections of the opinion. The ruling emphasized that the states also demonstrated a risk of irreparable harm, noting that compliance with the order "would burden the States with significant efforts and substantial costs."
The administration did not accept the ruling quietly. White House spokeswoman Abigail Jackson issued a statement expressing confidence in the order's legality.
"The President's executive order lawfully protects our elections, and we are confident that we will ultimately prevail in its implementation."
The sharpest response came from Deputy Chief of Staff Stephen Miller, who Fox News reported directed a pointed warning at Supreme Court Chief Justice John Roberts about the trajectory of the federal judiciary. Miller characterized Casper as a "rogue" Obama judge, framing the decision as part of a broader pattern of judicial resistance to the administration's agenda.
That kind of confrontation between the executive branch and the courts has become a recurring feature of the Trump presidency. In a separate matter, a federal judge stepped aside from an election interference case after direct White House pressure for recusal.
California Attorney General Rob Bonta, who helped lead the coalition of states challenging the order, framed the ruling as a clear win. Bonta told the New York Post that the states had prevailed on the merits.
"We sued President Trump over his attempt to unilaterally impose voting restrictions across the country, and we won."
Bonta added a warning of his own, saying his office remained "clear-eyed that President Trump's attacks on voting rights and our elections show no signs of slowing down." That language signals Democratic state attorneys general intend to keep filing suits if the administration pursues similar measures through other channels.
The ruling may have blocked the executive order, but it did not eliminate the underlying policy goal. If anything, it strengthened the argument that congressional action is the only viable route to requiring proof of citizenship for voter registration.
Trump has already shifted to that strategy. Newsmax reported that the president is actively lobbying Congress to pass the SAVE America Act, which would achieve the same citizenship verification requirements through legislation rather than executive fiat. Trump tied an unrelated bipartisan housing bill to the SAVE America Act, telling lawmakers he would not sign the housing measure unless Congress advances the election-security legislation alongside it.
That kind of legislative hardball carries its own risks. Republican lawmakers have occasionally struggled to rally behind executive priorities when courts strike them down. In a parallel situation, Republican senators acknowledged they lacked a legislative fallback if the Supreme Court struck down Trump's birthright citizenship order.
The SAVE America Act would place the citizenship-proof requirement on firmer constitutional ground by routing it through Congress, the branch that Casper's own ruling identified as the proper authority over election rules. Whether the votes exist to pass it remains an open question.
The administration has signaled it will appeal. The case would move to the U.S. Court of Appeals for the First Circuit, and the White House's public statements suggest it views the Supreme Court as the ultimate venue for resolution. Miller's warning to Chief Justice Roberts hints at the stakes the administration sees in the appellate process.
For now, the federal voter registration form remains unchanged. States will not face the compliance costs or administrative overhaul the executive order would have demanded. The question of whether voters must present documentary proof of citizenship before registering for federal elections sits squarely in Congress's lap.
Voter ID requirements continue to generate legal battles at the state level as well. In one notable case, a federal judge upheld North Carolina's photo voter ID law after years of legal challenges, a reminder that the judiciary does not always land on the same side of these disputes.
Investigators, legislators, and courts will need to determine whether the SAVE America Act can clear both chambers before the next federal election cycle. The clock is not generous.
An Obama-appointed judge told the president he cannot rewrite election rules on his own. The Constitution agrees, at least on paper. The real question is whether Congress has the will to do what the executive branch could not.
