Supreme Court Justice Ketanji Brown Jackson has delivered one of her sharpest public critiques yet of her conservative colleagues, condemning the court's repeated use of emergency orders to enable the Trump administration to implement policies that lower courts had found were likely illegal. Speaking for nearly an hour at Yale Law School in New Haven, Connecticut, Jackson called the orders "scratch-paper musings" that "seem oblivious and thus ring hollow" — unusually candid language for a sitting justice addressing the public directly rather than through formal written opinions.

The emergency docket Jackson targeted consists of appeals in cases still being heard in lower courts, where the Supreme Court is asked to intervene swiftly and does so without hearing oral arguments. Since the start of Donald Trump's second administration, the court has been asked to rule on 34 such emergency applications and has sided with Trump in the majority of cases, allowing controversial policies on immigration, steep federal funding cuts, and other matters to proceed in the interim. Jackson, who was nominated by President Joe Biden in 2022 to replace retiring Justice Stephen Breyer, described the orders — often issued with little or no written explanation — as "back-of-the-envelope, first-blush impressions of the merits of the legal issue." She argued that the court compounds this problem by then requiring lower courts to treat those hasty conclusions as binding guidance in other cases.

A further failing, Jackson said, is the court's tendency to weigh executive inconvenience against the concrete harm to real individuals affected by the policies, without adequately acknowledging those human costs. She pushed back firmly on the majority's reasoning that blocking a presidential policy constitutes harm significant enough to justify an emergency order in the government's favour. "The president of the United States, though he may be harmed in an abstract way, he certainly isn't harmed if what he wants to do is illegal," she said. She also described a broader institutional shift: "In recent years, the Supreme Court has taken a decidedly different approach to addressing emergency stay applications. It has been noticeably less restrained, especially with respect to pending cases that involve controversial matters."

Jackson's speech, posted online by Yale Law School on Wednesday, follows a similar public address by Justice Sonia Sotomayor at the University of Alabama the previous week, in which Sotomayor also criticised the conservative majority's approach. The two justices, along with Justice Elena Kagan, form the court's liberal bloc and have frequently dissented from the emergency rulings. The conservative majority currently numbers six on the nine-member bench, a balance shaped in part by Trump's appointment of three justices during his first term. Jackson acknowledged that conversations about the emergency orders had taken place among the justices internally, but said she chose to speak publicly hoping to be "a catalyst for change."

The episode underscores deepening tensions within the court. On the same day Jackson's Yale remarks circulated widely, Sotomayor issued a rare public apology to Justice Brett Kavanaugh for comments she had made at the University of Kansas, in which she had suggested he was out of touch with working-class people by referencing his professional family background. The remarks were seen as a breach of the court's usual decorum around personal references to colleagues, and Sotomayor acknowledged they had been "inappropriate" and "hurtful." The public exchanges among justices reflect the unusual degree to which the Supreme Court's internal fault lines have become visible to the American public at a moment of acute political tension over the boundaries of executive power.
