Supreme Court Justice Ketanji Brown Jackson accused the court’s conservative majority of "needlessly" injecting "chaos and uncertainty" into the 2026 midterms after the court lifted a lower-court block on key parts of President Donald Trump‘s executive order seeking new restrictions on mail-in voting.

Jackson Warns Ruling Could Disrupt Midterms

The court ruled 6-3 on Monday to stay a lower-court injunction that had blocked parts of Trump’s March 31 executive order in 23 Democratic-led states and Washington, D.C. The majority said the states challenged the policy too early because the directives had not caused concrete harm.

Jackson rejected that reasoning in a 23-page dissent. "This ruling violates well-established precedents concerning this Court’s equitable discretion and needlessly injects chaos and uncertainty into the upcoming midterm elections," she wrote, calling the court’s approach another step in a "Kafkaesque nightmare" for election-related challenges.

The decision does not determine whether Trump’s order is lawful. A separate nationwide injunction still blocks the Postal Service from enforcing one disputed provision, Reuters reported.
