In a sharply worded dissent this week, Supreme Court Justice Ketanji Brown Jackson lashed out at her fellow justices, accusing the Court of bending over backwards to favor the Trump administration. Her criticism came in response to a 5-4 decision allowing the National Institutes of Health (NIH) to cancel roughly $783 million in federal research grants that did not align with the administration’s priorities.
Jackson, appointed by President Joe Biden in 2022 and now the most junior member of the Court, claimed the ruling set a dangerous precedent by allowing the executive branch too much discretion in determining which research projects deserve taxpayer funding. “This is Calvinball jurisprudence with a twist,” she wrote, invoking the term coined in the comic strip Calvin and Hobbes—where rules are made up on the spot and serve the players’ interests. “Calvinball has only one rule: There are no fixed rules. We seem to have two: that one, and this Administration always wins.”
The ruling in question involved two separate 5-4 decisions. In the first, the Court allowed NIH to proceed with canceling existing grants that were inconsistent with Trump-era policy goals. These grants included projects focused on diversity, equity, and inclusion (DEI), COVID-19-related health disparities, and gender identity research—topics often aligned with left-wing academic agendas. In the second decision, the Court left in place a lower court’s block on new NIH guidance, which may limit future grant cancellations. Interestingly, conservative Justice Amy Coney Barrett, a Trump appointee, joined the liberal justices in both decisions, showing the Court’s internal divisions are not strictly ideological.
Jackson, however, appeared particularly irate that the NIH was being given what she viewed as unchecked authority. She argued that the grants were tied to “life-saving biomedical research” and that their cancellation would carry “real consequences for the law and for the public.”
Yet critics say Jackson’s reaction reveals more about her judicial philosophy—and perhaps her political leanings—than it does about any miscarriage of justice. Her lengthy dissent alone comprised more than half of the 36-page decision, a rarity in what was essentially an emergency ruling. Conservative legal scholar and George Washington University professor Jonathan Turley noted recently that Jackson has increasingly adopted a “histrionic and hyperbolic” tone in her writings, often painting her conservative colleagues as threats to democracy itself.
Indeed, this isn’t the first time Jackson has found herself on the losing side of a major decision. In a separate, high-profile ruling earlier this term, Justice Barrett directly criticized Jackson’s expansive judicial vision, accusing her of promoting an “imperial judiciary.” Barrett also cautioned Americans against giving undue weight to Jackson’s dissents, urging legal scholars and the public “not to dwell” on her dramatic framing of complex legal questions.
Barrett’s opinion in the NIH case also provided a crucial distinction. While she sided with Jackson and the liberal justices in denying part of the Trump administration’s request, she made it clear that she did so based on procedural grounds—not on the merits of the administration’s policy. She also emphasized that legal challenges to grant cancellations should come from grant recipients through the Court of Federal Claims, not through abstract legal theory.
What’s becoming increasingly clear is that Justice Jackson is struggling to adapt to the rigor of constitutional interpretation unmoored from partisan ideology. Her frequent, fiery dissents may energize left-wing media and activists, but they risk eroding the public’s trust in the impartiality of the Court.
As the Supreme Court continues to tackle contentious issues—many with direct ties to the legacy of the Trump administration—Americans are likely to see more friction among the justices. But the expectation, especially for a member of the nation’s highest court, is to rise above partisanship. Justice Jackson’s rhetoric, no matter how colorful, may only serve to deepen public cynicism rather than foster meaningful dialogue about the role of the judiciary.
