DOJ Rushes to Supreme Court as USPS Mail-In Voting Restrictions Face Imminent Block
The high-stakes battle over President Trump’s March 31, 2026 Executive Order (titled “Ensuring Citizenship Verification and Integrity in Federal Elections”) and the resulting U.S. Postal Service (USPS) mail-in voting restrictions has reached a fever pitch. In the first week of September 2026, the Department of Justice (DOJ) bypassed the normal appellate process to file an emergency application with the U.S. Supreme Court, seeking to overturn a temporary restraining order (TRO) that currently blocks the new rules.1
This preemptive move to the nation’s highest court came just hours before U.S. District Judge Indira Talwani held a highly anticipated hearing on September 3, 2026, to determine whether to issue a longer-lasting preliminary injunction that would block the USPS rules for the entire November midterm election cycle.
The finalized USPS rule, published in late August 2026, requires state and local election officials to submit their mail-in ballot envelopes to the USPS for design approval and upload detailed voter registration lists to a new federal portal. If a jurisdiction fails to comply, mail carriers are instructed to refuse delivery of their mail-in ballots.
During the September 3 hearing in Boston, Judge Talwani expressed deep skepticism about the readiness and legality of the USPS portal, which has been plagued by reports of "slapdash" development. A USPS whistleblower recently warned that the system’s rigid verification protocols could result in "catastrophic failure" and reject thousands of ballots over minor formatting errors.
When asked when the portal would go live and how it would handle submissions from 10,000 local jurisdictions, DOJ attorneys were unable to provide specific details.
"We’ve been here for a week and you can’t tell me the government is ready to go?" Talwani responded, incredulously.
In its emergency petition to the Supreme Court, Solicitor General D. John Sauer argued that blocking the rule "partially nullifies the Postal Service’s efforts to address the risk that the federal mails will be used to perpetrate voter fraud" and warned that keeping the rule blocked would sow "confusion and chaos."
"With respect to the November 2026 election, the order thus partially nullifies the Postal Service’s efforts to address the risk that the federal mails will be used to perpetrate voter fraud, a particularly pernicious species of fraud that dilutes the votes of lawful voters..."
However, voting rights groups and a coalition of 24 Democratic-led states argue that the rule is an unconstitutional federal takeover of election administration2 and would cause massive disenfranchisement. Judge Talwani noted that the administration had failed to provide any evidence of widespread mail-in voting fraud to justify the sweeping restrictions.
The Supreme Court's response to the DOJ's emergency stay application will determine whether the USPS restrictions are implemented for the midterms, which are less than two months away.
