A major legal battle unfolded in 2025 involving the National Institutes of Health (NIH) funding cuts initiated by the Trump administration during his second presidency. These cuts targeted nearly $800 million in research grants related to diversity, equity, and inclusion (DEI) initiatives, transgender health, COVID-19 studies, and other sensitive topics such as breast cancer, HIV prevention, and suicide prevention. The administration’s decision to cancel these grants sparked lawsuits by researchers, advocacy groups, and multiple states contesting the legality and discrimination behind the cuts.
Background and Origin of the Lawsuit
Beginning in early 2025, the NIH, under the guidance of Health and Human Services Secretary Robert F. Kennedy Jr., undertook a large-scale termination of approximately 2,300 federal research grants. The cancellations were based on allegations that these funded studies promoted “gender ideology” or “immoral” race- and sex-based preferences, which conflicted with the Trump administration’s policy priorities.
The affected grants included critical public health and biomedical research spanning diverse communities and medical conditions. Researchers who lost funding initiated lawsuits challenging the termination as both unlawful and discriminatory. A federal district court in Massachusetts initially ruled in favor of the researchers, ordering reinstatement of the grants and denouncing the cuts as arbitrary and capricious.
Supreme Court Ruling and Legal Proceedings
The Trump administration appealed, and in August 2025 the U.S. Supreme Court issued a narrow 5-4 ruling allowing the NIH to pause the reinstatement order and continue suspending nearly $783 million in grants. The court held that challenges to the grant terminations must be brought before a specialized federal court (the Court of Federal Claims) rather than the district court. While invalidating internal NIH guidance memos related to the cuts, the Supreme Court’s decision allowed the administration to proceed with its funding reductions pending further judicial review.
Chief Justice John Roberts joined the liberal justices in dissent, warning against the administration’s actions as a “breathtakingly arbitrary” attack on science and public health research. The ruling has been criticized as undermining grants supporting underrepresented groups and critical health issues.
Key Legal Claims and Allegations
- Violation of Federal Law: Plaintiffs argue the administration’s grant cancellations violate agency procedural rules and federal funding statutes.
- Discriminatory Impact: The termination disproportionately affects research on racial minorities, LGBTQ+ populations, and other marginalized communities.
- Unlawful Ideological Purge: The actions are described as politically motivated efforts to eliminate funding for DEI-focused and socially sensitive scientific inquiry.
Broader Implications and Public Response
The lawsuit and Supreme Court decision have profound implications for scientific freedom, public health research, and the intersection of politics and federal funding. Numerous scientific institutions and associations condemned the cuts, citing potential long-term damage to medical innovation and equity in science.
Congressional leaders and advocacy groups are exploring legislative responses to protect scientific research from political interference, emphasizing transparency, equity, and the scientific process.
