A federal judge in Massachusetts issued a preliminary injunction blocking new Postal Service rules designed to restrict mail ballots, according to Colorado Secretary of State Jena Griswold.
The injunction stops the USPS from implementing rules that came from President Trump's March 31 executive order on mail voting. On August 26, Colorado joined 24 other states and the District of Columbia in filing a lawsuit to block the USPS from implementing these rules.
Secretary of State Griswold said in a statement, "We are glad that this Court has stopped the Postal Service from impacting who can receive a ballot in the 2026 election. The Postal Service must stick to its job of delivering the mail, rather than trying to decide who gets to vote. We will continue to fight Trump to stop his unlawful attempts to suppress the vote and disenfranchise voters."
The injunction extended a temporary restraining order issued on August 27, which was limited to 14 days. The new preliminary injunction extends the block while the lawsuit proceeds.
The Postal Service has appealed the ruling to the First Circuit Court of Appeals, and the Trump administration has requested expedited review by the Supreme Court. The First Circuit has not yet ruled on the appeal.
With 60 days until the midterm election, the court's decision prevents voters in participating states from being affected by the USPS rule changes during the 2026 General Election.
