A written ruling details why a judge restored funding for many NIH grants.

A federal judge issued a stinging rebuke to the Trump administration, declaring that its decision to cancel the funding for many grants issued by the National Institutes of Health was illegal, and suggesting that the policy was likely animated by racism. But the detailed reasoning behind his decision wasn’t released at the time. The written portion of the decision was finally issued on Wednesday, and it has a number of notable features.

For starters, it’s more limited in scope due to a pair of Supreme Court decisions that were issued in the intervening weeks. As a consequence, far fewer grants will see their funding restored. Regardless, the court continues to find that the government’s actions were arbitrary and capricious, in part because the government never bothered to define the problems that would get a grant canceled. As a result, officials within the NIH simply canceled lists of grants they received from DOGE without bothering to examine their scientific merit, and then struggled to retroactively describe a policy that justified the actions afterward—a process that led several of them to resign.
