In a 5-4 ruling, the U.S. Supreme Court struck down a lower court order that sought to restore nearly $783 million in NIH grants terminated amid efforts to reduce diversity, equity, and inclusion research funding. The Court held that jurisdiction lies with the claims court, delaying reinstatement processes. The ruling preserves the invalidation of NIH’s DEI guidance criticized for discriminatory funding cuts. Researchers and public health advocates condemned the decision as an impediment to scientific progress and equity-related investigations.
