Federal Judge in Miami Strikes Down Noncitizen Voting Prosecution, Dealing Blow to Trump Election Crackdown

A federal judge in Miami has thrown out a criminal case against a noncitizen accused of voting illegally, ruling that the federal law underpinning the charge exceeds Congress's constitutional authority. The decision, issued Thursday by US District Judge David Leibowitz, represents a significant legal setback for the Trump administration's aggressive push to prosecute election fraud in the run-up to November's midterm elections.

The case centered on Chelsea Cox, a Florida resident who originally came to the United States from Jamaica. Cox was charged in October 2025 with casting a ballot in the 2020 presidential election despite not being a US citizen. Federal prosecutors brought the case under a statute that criminalizes voting by noncitizens in federal elections.

Leibowitz, who was appointed to the bench by former Democratic President Joe Biden, concluded that the Constitution reserves the power to set voter qualifications exclusively to the individual states, not to the US Congress. Because every state already mandates US citizenship as a prerequisite for voting, he reasoned, the authority to prosecute someone for violating that requirement rests with Florida rather than the Department of Justice.

In his written opinion, the judge noted that Florida possesses its own laws prohibiting the conduct Cox is accused of, and that the state "can and does" enforce them. The ruling effectively leaves the matter to state prosecutors, should they choose to pursue charges.

The decision applies narrowly to Cox's case and does not set a binding precedent for courts in other jurisdictions. However, its reasoning could prove influential: approximately 45 similar cases are pending across the country, and at least four other defendants have already raised the same constitutional argument in their defense.

According to court filings, Cox entered the United States as a tourist in 1999, overstayed her visa, and later obtained a Florida driver's license and registered to vote in 2012 using a fraudulent birth certificate from the US Virgin Islands. The government alleged that this registration led to her casting an illegal ballot in the 2020 presidential election.

President Donald Trump has repeatedly and falsely claimed that noncitizen voting—which is already prohibited and extremely rare—deprived him of victory in the 2020 election. He has characterized such voting as part of a wider Democratic effort to dilute Republican electoral support, a narrative that has fueled his administration's enforcement efforts.

Since returning to office in January 2025, the Department of Justice has charged at least 60 individuals with voting by noncitizens. The enforcement campaign has accelerated as the midterm elections approach, with administration officials framing the prosecutions as necessary to protect election integrity.

Yet an analysis by Reuters of 129 people charged with "voting by an alien" since 2021 paints a different picture. None of those defendants was accused of conspiring to sway an election, backing a particular candidate, or being paid to vote. Most were lawful permanent residents who had registered to vote either by mistake or based on incorrect advice from an election worker or government clerk.

That pattern suggests that many of the prosecutions target administrative errors or misunderstandings rather than deliberate attempts to subvert the electoral process. Critics argue that the federal crackdown risks criminalizing individuals who believed they were eligible to vote and had no intent to commit fraud.

Cox's attorney, Bruce Udolf, welcomed the court's ruling and expressed hope that authorities would not seek to deport his client. He cited her declining health conditions as a reason for leniency. The possibility of deportation remains a separate concern, as immigration enforcement operates independently of the criminal case that was dismissed.

The ruling also underscores a broader legal debate over the balance of power between federal and state authorities in election matters. The Constitution grants states primary responsibility for determining voter qualifications, a principle that Leibowitz found incompatible with the federal statute used to charge Cox.

Legal observers note that the decision could complicate the Justice Department's strategy of pursuing noncitizen voting cases in federal court, particularly if other judges find the constitutional argument persuasive. The pending cases nationwide may now face renewed challenges, potentially forcing prosecutors to rely on state-level enforcement instead.

For the Trump administration, the ruling arrives at an awkward moment. The White House has made election fraud a central theme ahead of the midterms, and the dismissal of a high-profile case could undermine its messaging. Administration officials have not yet indicated whether they will appeal the decision or adjust their enforcement approach.

The case also highlights the human consequences of the crackdown. Cox, who has lived in the United States for decades, now faces an uncertain future. While the criminal charge against her has been dismissed, the immigration consequences of her overstayed visa and fraudulent documents could still lead to removal proceedings.

As the midterm elections draw closer, the legal battle over noncitizen voting is likely to intensify. The Leibowitz ruling provides a significant precedent for defense attorneys challenging federal prosecutions, even if it does not bind other courts. Whether it marks a turning point or a temporary obstacle for the administration's enforcement agenda remains to be seen.

For now, the decision serves as a reminder that the Constitution's division of authority between federal and state governments continues to shape the contours of election law—and that efforts to centralize enforcement in Washington may run into deep-rooted legal limits. The Justice Department has not publicly commented on whether it will seek an appeal or reassess its pending cases in light of the ruling.
