WASHINGTON, DC — The U.S. Supreme Court ruled 7 to 2 September 14th to uphold a lower court, and stop implementation of restrictive new U.S. Postal Service mail-in ballot rules. But three justices signaled a reconsideration in the coming months.

The court’s refusal reads, “The application for stay presented to JUSTICE JACKSON and by her referred to the Court is denied. The Government is unlikely to succeed on the merits of its challenge to the District Court’s preliminary injunction. And the equitable factors applicable for obtaining emergency relief from this Court do not favor a stay,” UNQUOTE.  Justice Kavanaugh concurred; Alito and Thomas dissented.

The lower court’s decision blocked the dysfunctional USPS state voter citizenship list portal and redesign of ballot envelopes.  State election officials and a USPS whistleblower had warned that a lack of time and rushed software development could disenfranchise millions of voters, to which the court referred as “equitable factors.”   

For the midterms, voters should be able to vote by mail as usual, with the Postal Service merely delivering the mail, not verifying citizenship for every mail-in voter receiving or sending a ballot. 

However, in Kavanaugh’s concurrence and Alito and Thomas’ dissent, it was  suggested USPS might have the authority to make such rules, inviting another challenge in the coming months.  We’ve posted the decision at AmericanDemocracyMinute.org.   I’m Brian Beihl.
