The Supreme Court helped President Trump suppress mail-in votes. The unsigned opinion in Trump v. California released a federal judge’s hold on the President’s executive order directing the U.S. Postal Service to stop mailing ballots to voters the Postal Service has not pre-enrolled — without deciding whether the President has any authority to do what his own order commands. Sixty days before the midterm elections, that is the shadow docket — the Court’s emergency calendar of unsigned orders — doing what it does.

The March executive order tells the USPS to draft rules standardizing ballot envelopes and to maintain a “Mail-In and Absentee Participation List” for each state. The order states bluntly: “The USPS shall not transmit mail-in or absentee ballots from any individual unless those individuals have been enrolled.” That text is mandatory. It does not say “draft rules about transmitting unenrolled voters’ ballots.” It says the USPS shall not transmit them.

The unsigned opinion reads the order as a directive to “initiate the process of proposing a rule,” reserving judgment on “whatever concrete changes the rule may produce”: “On that score, time will tell.” That reading has a defense. The enrollment mechanism does not yet exist; the operative prohibition will only attach once the rules take effect; until then, the order is rulemaking direction. Federal courts should not enjoin executive rulemaking in advance of the rules.

The defense fails. The unsigned opinion also says the order “imposes no legal requirements on the States (or, for that matter, on anyone outside the Executive Branch).” Voters are outside the Executive Branch. Voters who must enroll to have their ballots mailed are under a legal requirement the order imposes on them. The unsigned opinion’s own framing of the order contradicts its own conclusion. The order imposes a legal requirement on every voter who has not been pre-enrolled: their ballot will not be mailed.

Justice Ketanji Brown Jackson’s separate twenty-three-page dissent reads the order the way its text reads. “The President does not have any legal authority,” Justice Jackson wrote, “to require that elections be conducted in accordance with his preferences — or to withhold delivery of mail-in ballots that are not formatted consistent with the President’s wishes.” She called the situation “Kafkaesque.” The unsigned opinion refused to engage her reading of the order. It refused to engage her reading of the Constitution. It released the federal-court hold.

Justice Jackson’s dissent states the governing right-instrument the unsigned opinion avoided. The order claims authority under the President’s general executive power over USPS operations. The constitutional provision the dispute turns on is Article I, section 4, clause 1 — the Elections Clause — which assigns the power to regulate the times, places, and manner of federal elections to the state legislatures, with authority in Congress to “make or alter such Regulations.” The President is not named. The Constitution does not give the President any affirmative role in the administration of federal elections. Justice Jackson’s dissent operates on that constitutional baseline. The unsigned opinion does not engage it.

Justice Sonia Sotomayor, joined by Justice Elena Kagan, called the unsigned opinion’s procedural disposition “merely postpones” the merits in a four-page dissent. That characterization is too kind. The unsigned opinion did not postpone the merits; it released an injunction without engaging them. The operative prohibition on mailing unenrolled voters’ ballots is in force now, as the lower courts proceed. Justice Jackson’s twenty-three pages are the audit. The unsigned opinion is the shadow-docket order that ratified a presidential directive whose authority the Court has not examined.

The rule itself makes the deferred merits question concrete. The USPS published its final rule on Friday, effective immediately, though blocked for the moment by a separate injunction in a different case. The voter list is drawn “entirely” from state data; the postal Service “will not change the content” or cross-check against outside sources. The documents are, in the rule’s own words, “a manifest” meant “to assist election officials and law enforcement to understand who may have been mailed a ballot.” The rule rejects the suggestion that any ballot can be classed as “nonmailable.” A ballot that does not meet a state’s outer-envelope requirement is, by the rule’s own framing, a logistics problem.

Logistics problems are what the Postal Service exists to solve. The Justice Department’s filings defend the rule as routine postal operations. But the President’s executive order does not say “draft rules about logistics.” It says “shall not transmit mail-in or absentee ballots from any individual unless those individuals have been enrolled.” The Justice Department’s defense and the executive order’s text do not match. The unsigned opinion does not address the gap. Justice Jackson’s dissent does.

Ten pages of unsigned opinion. Twenty-three pages of dissent. Sixty days of midterms. The Court has chosen its reading. The voters will choose theirs.
