On 2026-07-13, the U.S. Department of Justice asked the Boston-based 1st U.S. Circuit Court of Appeals to stay a temporary restraining order that blocks the U.S. Postal Service from enforcing a new rule tightening mail-in voting requirements. ^[1] Voting rights groups filed a lawsuit to block Florida's SAVE Act. ^[2] Justice Department lawyers told the 1st Circuit on 2026-07-13 that Judge Talwani's ruling was 'gravely mistaken' and that the lawsuit rests on an unfounded premise that the U.S. Postal Service intends to seize control of election administration. ^[3] On 2026-07-09, U.S. District Judge Indira Talwani, an appointee of Democratic President Barack Obama, issued a temporary restraining order at the request of Democratic-led states and voting rights groups, concluding that the USPS rule risked disenfranchising voters and was likely unlawful under the U.S. Constitution. ^[4] The U.S. Postal Service rule, issued to implement an executive order signed by President Donald Trump in March 2026, requires states to supply the USPS with lists of mail ballot recipients and requires all outbound and return ballot envelopes to bear unique barcodes. ^[5] The lawsuit challenges the constitutionality of the SAVE Act. ^[6] The legal challenge aims to prevent the SAVE Act from taking effect. ^[7]
