D.C. Appeals Court Revives USPS Mail-Voting Rule, but 1 Injunction Still Blocks It

Q: What happens to mail-in ballots if states cannot meet the new federal barcode and voter list requirements?

If states cannot meet the proposed barcode and voter-list requirements, USPS says those ballot mailings could be rejected, returned to the sender, or not delivered until the state provides the required information. Under the proposed rule, states would have to give USPS a voter participation list and unique Intelligent Mail barcodes for outbound and return ballot envelopes. USPS would use that data to verify that ballots are being sent to people on the state’s list and that the mailpieces meet federal design standards. If a mailing does not match the list, lacks the required barcode, or comes from a state that has not certified compliance, USPS says it would not accept the mailing and would return it to the authorized election mailer for correction. That means eligible voters could face delays or fail to receive ballots if their state cannot comply on time or if there are data errors. USPS has also said it would not take responsibility for delays before a ballot mailing is formally accepted into the mailstream. At the same time, this is still a proposed rule, not a final one, and its legality remains unresolved. The recent appeals court ruling only lets USPS continue working toward finalizing the rule while the case proceeds. Separately, other federal court orders have blocked key parts of the underlying executive order, so the non-delivery policy is not settled law at this point.

A unanimous 3-judge D.C. Circuit panel paused a lower-court order that had barred the Postal Service from advancing a Trump-backed rule tightening mail-in voting procedures.
The court said the administration is likely to win because the NAACP suit is premature—the rule is not final—and the proposal is not covered by the USPS's 2021 election-mail settlement.
That win does not let USPS enforce the policy yet, because a separate Massachusetts injunction issued last month still blocks the rule.
Under the proposal, USPS could refuse to deliver mail ballots in states that do not provide approved-voter lists, according to Postmaster General David Steiner's Senate testimony last month.
The ruling could bolster the administration's push in other appeals courts to get the policy in place before the November midterm elections.

The 2026 USPS Mail-In Voting Rule: Legal Battles, Federal-State Tensions, and the Future of Election Integrity

Overview

On July 18, 2026, the D.C. Circuit Court of Appeals issued a ruling that temporarily allows the USPS to move forward with its controversial mail-in voting rule, lifting a previous block and enabling the agency to develop and implement the policy. However, a separate injunction from Judge Talwani continues to block enforcement of the rule in 24 specific jurisdictions, meaning the USPS cannot apply the rule nationwide. As a result, the implementation of the USPS policy remains limited, reflecting the ongoing legal complexities and the fragmented state of mail-in voting regulations across the country.
