The legal status of mail-in voting

Newsworthy - The Supreme Court’s emergency order let parts of a federal mail-ballot screening plan move ahead, then lower courts pulled it back, leaving voters and states in limbo before the midterms.

On August 24, 2026, the Supreme Court issued an emergency order that let the administration proceed, for now, with parts of its mail-ballot policy while lawsuits continue. The order did not decide the final legality of the rule. It lifted one block but left other limits in place around the country. The mixed result created a patchwork. Some states faced new steps. Other states continued under injunctions from lower courts that viewed the policy as unlawful.

The administration’s legal theory frames the United States Postal Service as a gatekeeper for secure ballot mail. Supporters say postal rules on lists and barcodes help detect fraud and protect chain of custody. Two justices argued the Postal Service has broad mail security powers that can include ballot handling standards. They said there is a strong interest in enforcing the rule while cases move ahead. That view did not control the Court but signals a serious legal debate.

The Postal Service rule requires states to submit mail voter lists and use envelopes with unique barcodes tied to each ballot. It also sets up a portal to match ballot mail against those lists. Ballots that do not match could be rejected for delivery under the policy, according to court filings and reporting. These steps amount to a federal screen layered on top of state election systems. That is why lawsuits call the plan an unprecedented shift in ballot processing.  MORE
