A federal judge appointed by Barack Obama has permanently blocked President Trump’s executive order that would have required documentary proof of American citizenship on federal voter registration forms, ruling the White House exceeded its constitutional authority over elections in the case California v. Donald Trump.

Judge Denise Casper converted a preliminary injunction into a permanent ban and declared five sections of the executive order unconstitutional, saying the president lacks the power to set national election rules. The move came after 19 states sued to block the directive, and it removes the order’s proof-of-citizenship requirement from federal voter registration for now.

The executive order, signed in March 2025 under the title “Preserving and Protecting the Integrity of American Elections,” directed the Election Assistance Commission to add documentary proof-of-citizenship to the national mail-in voter registration form. It also aimed to alter the federal postcard form used by military and overseas voters so it would require either proof of citizenship or proof of eligibility to vote in the relevant state.

Beyond registration paperwork, the order addressed late-arriving mail ballots and threatened to withhold federal funds from states that refused to comply, and it invoked the need to guard against “illegal voting, discrimination, fraud, and other forms of malfeasance and error” in American elections. The directive sought a uniform federal floor for verification in systems that many critics say are inconsistent from state to state.

Casper found Sections 2(a), 3(d), 4(a), 7(a), and 7(b) unconstitutional and void, calling them “ultra vires and violating the separation of powers under the United States Constitution.” Her injunction bars all defendants except President Trump personally from enforcing the proof-of-citizenship provisions, leaving the Election Assistance Commission unable to implement the changes the order directed.

At the heart of the decision is Casper’s view that the Constitution does not grant the president specific authority over elections, which she said belongs to the states and to Congress. On that basis she concluded the order exceeded presidential power and intruded on the roles assigned by the framers.

This ruling followed an earlier decision issued in April 2025 by U.S. District Judge Colleen Kollar-Kotelly, another Democratic appointee, who also ruled against the order. That string of defeats for the administration’s election-reform agenda has drawn attention to the role of judges appointed by Democratic presidents in blocking executive action.

Casper also wrote that “there is no evidence in this record of widespread ‘illegal voting, discrimination, fraud, and other forms of malfeasance and error’ within American elections.” That language is important and contested; the absence of proof in a single court record does not automatically mean the risks identified by the White House are nonexistent, especially where detection mechanisms differ widely between jurisdictions.

The FBI has deployed agents to investigate alleged voter fraud in at least one major American city, and those investigations suggest isolated problems do exist. Whether those incidents qualify as “widespread” is debatable, but they complicate a straightforward reading of the court’s assurance that systemic fraud is not present.

The pattern of Obama-appointed judges enjoining Trump administration policies has become familiar across a range of issues, from benefits reform to immigration and now elections. When the same segment of the judiciary repeatedly blocks an administration’s priorities, voters are right to ask whether results reflect legal principle or political preference.

Questions about judicial conduct and impartiality have been raised in other election-related cases, and those concerns feed a broader erosion in public confidence that the bench stands above politics. Judge Casper, appointed to the District of Massachusetts in 2010, has overseen this litigation since the coalition of states filed suit, which carries the case number 25-cv-10810.

The White House pushed back through spokeswoman Abigail Jackson, who said “the President’s executive order lawfully protects our elections, and we are confident that we will ultimately prevail in its implementation.” California Attorney General Rob Bonta celebrated the decision but warned that the fight is ongoing, saying “While we are proud of this result, we are clear-eyed that President Trump’s attacks on voting rights and our elections show no signs of slowing down.”

“Generations of Americans fought tirelessly for the right to vote, and we honor their legacy by protecting that right against anyone who tries to undermine it.”

That declaration raises a direct question: how does requiring proof of citizenship “undermine” voting? Citizens who can prove their status would not lose access; those who cannot would simply be unable to establish they have the legal right to participate. Treating verification as automatic suppression collapses the distinction between the right to vote and the act of voting.

If Casper’s separation-of-powers reasoning holds, the remedy is legislative. The SAVE America Act has been floated as the statutory route to provide Congress’s authority for citizenship-verification requirements, and the administration has pressed lawmakers to act. Passing a law would neutralize the executive-overreach argument and force elected representatives to stake positions on whether verification is appropriate.

A congressional vote would be clarifying: progressives argue noncitizen voting is rare and verification imposes an unjust burden, yet many of those same officials resist audits, citizenship checks, and database cross-referencing that would measure the problem. Relying on the absence of data to deny the need for verification creates a circular protection for the status quo.

The legal fight is far from over. The administration intends to appeal, and the case could travel up to the Supreme Court, where the balance between presidential action and congressional authority on election administration would finally be decided. Meanwhile, federal mail-in registration will remain without a documentary proof-of-citizenship requirement, and the Election Assistance Commission is barred from acting on the president’s directive.

Five sections of the executive order now stand voided and two are permanently enjoined, leaving the federal postcard form for military and overseas voters unchanged as well. In most areas of life, proving you are who you say you are is not oppression. It is common sense, and the fact that it may take an act of Congress to require it for voting tells you a lot about who benefits from the current system and who is motivated to keep it that way.
