Connecticut’s online absentee-ballot application portal will open Saturday, September 19, without a new set of federal postal requirements that state officials said could have disrupted the November election. The U.S. Supreme Court on September 14 denied an emergency stay requested by the U.S. Postal Service and the Trump administration, leaving a nationwide preliminary injunction against the rule in place.
The immediate consequence is operational, not ideological: Connecticut can continue preparing absentee-ballot mail under its existing system. The blocked Postal Service rule would have required election officials to submit outbound and return-envelope designs for federal review, use specified election-mail markings and voter-specific barcodes, register for a federal portal and upload voter information. Mailings that failed the requirements could have been returned to the state for correction.
The Supreme Court’s brief order said the government was unlikely to succeed in challenging the injunction and that the equities did not favor a stay. Justice Brett Kavanaugh agreed that applying the rule to the 2026 election would likely be arbitrary and capricious because state and local officials lacked sufficient implementation time, while noting that the Postal Service may have authority to issue such standards generally. Justices Samuel Alito and Clarence Thomas dissented. The decision preserves the status quo for this election; it does not finally invalidate the rule.
Connecticut Attorney General William Tong, whose office joined a coalition of 25 states challenging the requirements, said the injunction will continue to block the federal approval, portal and voter-data provisions. His office called the order a victory for election administration. The Postal Service’s position is that the rule falls within its legal authority and would improve ballot-mail processing through standardized envelopes and unique barcodes; it has said it will comply with court rulings.
What Connecticut voters need to know
The timing is significant because Connecticut is entering its first statewide general election with no-excuse absentee voting. According to the secretary of the state’s 2026 absentee-voting calendar, any active registered voter may apply without stating a reason. The online application portal opens September 19, town clerks begin issuing ballots October 2, the application deadline is November 2 and Election Day is November 3.
Applying is not the same as voting. A town clerk must process the application and issue the ballot, and the completed ballot must be returned to the voter’s town clerk by mail, in person or through an authorized secure drop box. State officials advise voters using the mail to allow enough time for delivery.
The scale may be substantially larger than in the last general election. Connecticut told the courts it expects to mail roughly 175,000 to 200,000 absentee ballots in 2026, according to court filings reviewed by CT Insider. The state’s official 2024 tally recorded 120,422 absentee ballots received, of which 118,362 were counted. That makes the preserved rules and Saturday’s portal opening practical milestones for voters and local clerks, while the broader federal litigation continues.
