Federal Judge Blocks USPS Mail Ballot Envelope Rules for November 3 Elections
Judge Talwani issued a preliminary injunction on September 4, 2026, halting key provisions of a USPS rule that would have required mandatory envelope standards and agency review for outbound mail ballots in elections on or before November 3, 2026. The court found plaintiffs likely to succeed on claims that the rule exceeded USPS statutory authority and intruded on state election administration, while noting the record contained no evidence of fraudulent mail voting to justify the rule's compressed 60-day implementation timeline affecting roughly 10,000 jurisdictions. The administration has sought emergency relief at the Supreme Court, but no ruling on that application or a new First Circuit appeal from the preliminary injunction had been established as of September 5.
