The U.S. Supreme Court declined on Sept. 14, 2026, to lift an injunction that stops new federal requirements for mail-in ballots. This ruling ensures that Hawaii will continue its existing vote-by-mail system without the mandate for specific barcodes or USPS design reviews.
Why it matters
The court determined the federal government was unlikely to succeed in its challenge, while state officials argued that meeting the new federal requirements within the tight election window was impossible. This decision provides stability for state-run mail systems ahead of the November 2026 midterm election.
In the 2026 primary election, 97.3% of Maui voters cast mail ballots compared to 921 in-person votes. The county maintains five in-person voting locations, including the Hana site, which is scheduled to be open for one day on Oct. 24.
The players
Donald Trump
Donald Trump is the current President of the United States who issued the executive order regarding mail-in ballot distribution.
U.S. Supreme Court
The U.S. Supreme Court is the highest federal court that declined to lift the injunction blocking new voting requirements.
USPS
The United States Postal Service is the federal agency that was directed to review ballot designs and receive voter lists under the executive order.
The details
President Donald Trump issued an executive order on March 31, 2026, which sought to force changes to ballot envelopes and mandate states to provide voter lists to the USPS. Federal courts issued preliminary injunctions against these requirements, citing the state election office's inability to implement such technical changes in time for the current cycle.
Timeline
March 31, 2026: President Trump issued an executive order on mail-in ballot distribution.
Sept. 14, 2026: The Supreme Court declined to lift the injunction against new USPS requirements.
Oct. 16, 2026: Registered voters are expected to start receiving their mail-in ballots.
Oct. 24, 2026: The Hana in-person voting location will be open to residents.
Nov. 3, 2026: Election Day for the 2026 midterm election occurs.
Political Context
Opponents of the injunction argue that the executive order is necessary to standardize ballot security measures across all states. Conversely, state election officials maintain that federal intervention disrupts established voting procedures and creates insurmountable administrative burdens.
Hawaii residents will continue to receive and cast ballots using the established system without the proposed USPS changes. Voters can expect to receive their ballots by mail beginning October 16.
The takeaway
The court's decision provides immediate clarity for voters who rely on the established mail-in system. Residents should verify their registration status and monitor their mail as ballots are distributed in mid-October.
What happens next
Legal challenges regarding the new voting requirements are expected to continue beyond the November 3, 2026 election.
