Kavanaugh Signals Future Path for Trump's Mail Ballot Rules

Supreme Court Justice Brett Kavanaugh has indicated that the United States Postal Service (USPS) may have the statutory authority to implement mail ballot rules proposed by former President Donald Trump in the future. However, his concurring opinion in United States Postal Service, et al. v. California, et al. agreed with the majority that these rules are not permissible for the upcoming 2026 midterm elections.

The Supreme Court on Monday denied the Trump administration’s emergency request to lift a lower court injunction that had blocked the USPS rule. The majority ruled that the government was “unlikely to succeed on the merits” of its challenge, effectively keeping the rule inactive for the 2026 midterms, as ballots have already been sent out.

Despite this denial, Kavanaugh's written concurrence stated, “In my view, based on the briefing the Court has received at this interim stage, there is at least a fair prospect that the final rule falls within the Postal Service’s statutory authority.” This statement has been interpreted by some as providing a potential pathway for the rules to be implemented in future elections.

Jason Snead, executive director of the Honest Elections Project, told Fox News Digital that Kavanaugh “threw the government a lifeline by saying that he views it as likely that they do have the statutory authority.” Snead anticipates that the case could return to the Supreme Court and suggested that the rules might be allowed to take effect before the 2028 presidential election.

A dissent written by Justice Samuel Alito and joined by Justice Clarence Thomas also raised questions about the majority's decision. Alito argued that the government had met the necessary criteria for a stay and questioned the standing of some plaintiffs, describing their reliance on a legal strategy as a "Hail Mary pass."

The USPS rule in question requires federal ballot-mail envelopes to feature an election-mail logo, be scannable by high-speed processing equipment, and include a unique barcode for each voter. It also mandates that states upload certain voter information to a Postal Service portal.

A coalition of 24 Democratic state attorneys general challenged the rule, asserting that it infringes upon the Constitution's Elections Clause, which reserves the power to regulate elections for Congress. The Trump administration contended that the USPS was acting within its authority to regulate mail, rather than election procedures.

Eric Wessan, Iowa's Solicitor General, noted that timing was a critical factor in the Supreme Court's decision to maintain the status quo for the midterms. He pointed out that earlier litigation and an injunction in Massachusetts had delayed the Postal Service's ability to finalize and publish the rule. Wessan suggested that the same outcome might not apply to future election cycles, such as 2028.

Abhishek Kambil expressed surprise at the majority's unreasoned order, especially following a previous stay granted in a Missouri case that also lacked detailed explanation. Kambil noted that with significant stakes involved, a more thorough explanation from the court would have been expected.

Snead believes that without the immediate pressure of an election, states may face a more challenging legal battle to oppose the USPS rules in the future. He described the rules as basic measures to enhance mail ballot integrity, such as standardizing envelope design and using existing state lists of eligible mail voters for tracking purposes.
