Shibbir Ahmed, Washington, D.C. — A second federal judge has blocked the Trump administration from implementing new restrictions on mail-in voting, delivering another legal setback to the administration as the 2026 midterm elections approach.

U.S. District Judge Carl Nichols in Washington issued a preliminary injunction blocking new U.S. Postal Service rules that would impose stricter requirements on mail-in ballots. His ruling follows a similar decision by Boston-based U.S. District Judge Indira Talwani, who also blocked the rules.

The disputed regulations would require states to provide voter eligibility information to the Postal Service and comply with new ballot-envelope requirements, including unique barcodes. The administration says the measures are intended to strengthen election security and ensure that mail ballots are properly verified.

Opponents argue that the federal government does not have the authority to impose such requirements on state-run elections and warn that the changes could prevent otherwise eligible voters from casting valid ballots.

Judge Nichols, a Trump appointee, concluded that the Postal Service had exceeded its authority and that implementing the rules could make it harder for some voters to participate in elections.

The legal battle comes as states begin preparing to distribute mail ballots for the November midterm elections. The Trump administration has already asked the U.S. Supreme Court to intervene in the broader dispute and overturn an earlier order blocking the rules.

The Supreme Court’s eventual decision could determine whether the administration’s proposed mail-voting restrictions take effect before the midterms. The case has become part of a broader national fight over federal authority, voting access and election administration.

All 50 states allow some form of voting by mail, although the rules and availability vary from state to state. With the midterm elections approaching, the outcome of the court battle could have significant consequences for voters and election officials across the country.

Shibbir Ahmed, Washington, D.C.: Nearly two dozen Democratic-led states have filed a new lawsuit challenging President Donald Trump’s executive order seeking to restrict mail-in voting. The lawsuit was filed against the U.S. Postal Service (USPS).

The legal action seeks to block the Trump administration’s new rules governing mail-in ballots before the midterm elections scheduled for November. Under the new rules, envelopes containing mail-in ballots must meet specific design and barcode standards, while states would also be required to provide USPS with lists of eligible voters.

The states argue that the new USPS rules interfere with their constitutional authority over elections. They also warn that implementing changes so close to the midterm elections could create significant administrative and logistical challenges for voters and election officials.

In an earlier case involving the same issue, the U.S. Supreme Court ruled in favor of the Trump administration. However, the court did not make a final determination on whether Trump’s order itself was lawful. Instead, it lifted a lower-court injunction after finding that the earlier lawsuit had been filed prematurely.

The new lawsuit involves 23 states, the District of Columbia, and the governor of Pennsylvania. The case was filed in a federal court in Massachusetts. The Trump administration, meanwhile, says the new rules are intended to strengthen the security of mail-in voting. The states, however, are concerned that the new requirements could disrupt the mail-voting process during the November elections.

The key issue: With the 2026 midterm elections approaching, a new legal battle has emerged between the Trump administration and Democratic-led states over control of mail-in voting. The dispute could eventually return to the Supreme Court.
