As of July 11, 2026, the case is still moving on two tracks. In January 2026, the First Circuit affirmed a separate district court ruling blocking NIH’s attempt to cap indirect-cost reimbursement rates, and Congress’s FY2026 appropriations bill reinforced that protection. But the core appeal over the mass grant terminations — argued before the First Circuit on January 6, 2026 — remains undecided, with the administration now arguing the case is moot. Meanwhile, July 2026 is the deadline under the December 2025 settlement for NIH to finish deciding on remaining frozen and stalled applications, though NIH’s own review panels are short-staffed, with 13 of 21 poised to lose all members by year’s end.

The NIH grants termination lawsuit is one of the most significant federal funding legal battles in decades. Starting in February 2025, the Trump administration canceled thousands of research grants without warning or explanation, triggering federal lawsuits, a blockbuster court ruling, and a partial settlement by year’s end.

The stakes are enormous. The NIH terminated more than 2,600 grants totaling $8.9 billion. These weren’t obscure projects. They were active studies on Alzheimer’s disease, HIV prevention, cancer, and health disparities.

This article covers the full story from start to finish. You’ll learn what grants were cut, who sued, what every major court ruling means, and where the case stands in 2026.

What Is the NIH Grants Lawsuit About?

The NIH grants termination lawsuit challenges the federal government’s decision to cancel hundreds of active research grants without following its own legal procedures. The lawsuit argues that NIH and its parent agency, HHS, failed to follow proper procedure when canceling those research grants, and that the reason given for termination was arbitrary and capricious and therefore illegal.

At its core, the case is about process and power. Federal agencies cannot simply cancel lawfully awarded grants because a new administration dislikes the research topic.

For decades, terminations of ongoing NIH grants have been exceedingly rare. NIH has been guided by Congressional mandates, regulatory requirements, and scientific expertise when determining what research to prioritize and fund.

The lawsuit says that changed in 2025. NIH abruptly terminated hundreds of grants, many closely aligned with topics such as transgender health, environmental health, vaccine hesitancy, workforce diversity, and COVID-19. Researchers were given no meaningful explanation.

The legal argument centers on the Administrative Procedure Act, the separation of powers, and specific statutory mandates from Congress. If the government wins, it can defund research programs for purely political reasons. If the plaintiffs win, those grants must be reviewed and restored based on scientific merit alone.

Which NIH Grants Were Terminated?

The terminated grants covered a wide range of topics that the Trump administration labeled as “disfavored.” Beginning in February 2025, the Trump administration issued a series of directives to terminate large numbers of grants and refuse to consider certain categories of pending grant applications if they concerned topics declared disfavored, such as grants related to DEI, gender ideology, and similar research areas.

But the cuts went well beyond DEI programs. NIH has “unpublished” nearly 100 notices of funding opportunity calling for grant applications on topics including health disparities, workforce diversity, and research with sexual and gender minorities.

Real scientists doing critical work got caught in this sweep.

• Brittany Charlton (Harvard): Five grants studying LGBTQ adolescent reproductive health were canceled.
• Nisha Acharya (UC San Francisco): Her $3.3 million project studying the effects of shingles vaccination on ocular shingles infections was terminated, apparently because its summary included the word “hesitancy” in a different context.
• Nikki Maphis (University of New Mexico): A grant application for Alzheimer’s disease and alcohol use research was frozen.

The sweep was blunt. It targeted keywords, not actual scientific content.

How Many NIH Grants Were Canceled?

The scale of the terminations shocked the research community. About $800 million in funding for hundreds of federal research grants related to topics such as health disparities, LGBTQ+ health, and vaccines was at stake.

That figure only covers the grants directly challenged in the two main lawsuits. The total picture is much larger.

NIH terminated more than 2,600 grants totaling $8.9 billion, according to reports published after the June 2025 ruling. The lawsuit filed in April counted a minimum 678 research projects worth over $2.4 billion terminated by NIH at that time.

Think of it like a sudden eviction notice for thousands of scientific projects, many years in the making, with no appeal process offered.

The University of Massachusetts alone saw review delayed on 353 NIH grant applications because of the agency’s anti-DEI directive, according to reporting by Higher Ed Dive.

Key Takeaway: The NIH terminated over 2,600 grants worth roughly $8.9 billion. The core lawsuits focused on approximately $800 million in actively challenged grants.

Who Filed the NIH Grants Lawsuit?

Two separate lawsuits were filed in April 2025, and both landed before the same federal judge in Massachusetts.

On April 2, the American Civil Liberties Union, the ACLU of Massachusetts, Protect Democracy, and the Center for Science in the Public Interest filed a lawsuit on behalf of individual researchers, along with the American Public Health Association (APHA), the UAW, and Ibis Reproductive Health.

A second parallel lawsuit was filed by a group of 16 state attorneys general. That case argued separately that the cuts violated the APA, the Constitution’s separation of powers, and the Public Health Service Act.

The plaintiffs in the APHA case included:

• American Public Health Association (APHA): Primary professional association for biomedical researchers
• United Auto Workers (UAW): Representing researchers whose grants were canceled
• Ibis Reproductive Health: A reproductive health research organization
• Four individual scientists: Including Harvard epidemiologist Brittany Charlton, whose five LGBTQ health grants were canceled

APHA and UAW brought the suit on behalf of their impacted members. The individual plaintiffs gave the case human faces. Real scientists, with real projects, whose careers were upended overnight.

Judge William Young’s NIH Ruling Explained

Judge William Young delivered a landmark ruling on June 16, 2025. Young, appointed by then-President Ronald Reagan in 1985, said from the bench that NIH’s explanations were “bereft of reasoning, virtually in their entirety,” and declared that the directives were “of no force and effect. They are void and illegal.”

He did not stop at procedure. Young also said the terminations were rooted in discrimination against racial, sexual, and gender minority groups. “I’ve sat on this bench now for 40 years and I’ve never seen government racial discrimination like this,” he said.

The ruling covered the grants held by the specific plaintiffs in the two lawsuits. It did not automatically reinstate all 2,600-plus terminated NIH grants nationwide.

When Young asked NIH’s attorney how any specific grant project had supported unlawful discrimination, as NIH’s termination letters suggested, the attorney was unable to point to an example in the evidence submitted to the court.

That exchange said everything. The government had no answer.

A senior NIH official sent a memo instructing agency staff to stop terminating grants: “Effective immediately, please do not terminate any additional grant projects.” The order came hours after the ruling.

Supreme Court NIH Grants Stay: August 2025

The win was short-lived. The Trump administration appealed immediately, and the case reached the Supreme Court fast.

On August 21, 2025, the Supreme Court granted the Trump administration’s request to stay a district court’s judgment blocking NIH from terminating more than $780 million in federal grants that the agency determined had promoted DEI, gender identity, and COVID-19 research inconsistent with the administration’s policy directives.

The vote was 5 to 4. Justice Barrett wrote in a partial concurrence that the district court “likely lacked jurisdiction to hear challenges to the grant terminations, which belong in the Court of Federal Claims.”

This was a critical procedural twist. The Supreme Court didn’t say the terminations were legal. It said the wrong court heard the challenge.

In practical terms, the ruling effectively means that canceled NIH grants would not be immediately reinstated, despite the district court’s vacation of the guidance. Individual grant termination decisions must be challenged on contractual grounds under the Tucker Act in the U.S. Court of Federal Claims.

Key Takeaway: The Supreme Court’s August 2025 stay did not rule the terminations legal. It redirected the fight to a different court and left the underlying constitutional questions unresolved.

NIH Lawsuit Settlement: December 2025

Despite the Supreme Court setback, the lawsuits kept moving. By late December 2025, a significant settlement emerged.

The Trump administration reached an agreement to reevaluate research projects left in bureaucratic limbo while the lawsuit over the termination of thousands of NIH grants moves through the courts.

The December 29, 2025, settlement addressed a specific category of harm: grant applications that had been frozen, denied, or withdrawn, rather than grants that had already been terminated and funded.

Under a stipulated dismissal, NIH agreed to use its standard process to render decisions on the plaintiffs’ stalled applications, which address urgent public health issues including HIV prevention, Alzheimer’s disease, LGBTQ+ health, and sexual violence.

The agreement also confirmed that the close of Federal Fiscal Year 2025 would not block NIH from reviewing or awarding any of the stalled applications. Researchers who had been waiting in limbo for nearly a year finally had a path forward.

NIH Settlement: What the State Attorneys General Achieved

The state attorneys general reached their own parallel settlement on December 29, 2025. Their case focused on grant applications rather than already-funded terminations.

The National Institutes of Health reached a settlement with 16 states over delayed reviews of research grant applications representing potentially billions of dollars for university and other institutions’ projects.

Sixteen state attorneys general had sued in April after NIH withheld final decisions on hundreds of grants. Attorneys general hailed the settlement as creating a path forward for federally funded medical research.

The settlement is not a total victory. Not affected by the settlement are nearly 850 terminated grants, which a federal judge previously ruled were illegally cut by the Trump administration. Those remain in active litigation.

What the settlement does:

• Requires NIH to review all frozen/denied/withdrawn applications
• Sets firm deadlines by application submission date
• Confirms reviews will proceed on scientific merit, not political criteria
• Protects applications even after Fiscal Year 2025 ended

NIH Grant Applications Review Agreement 2026

The December 2025 settlement created legally binding review deadlines for NIH grant applications. These are not vague promises. They are court-stipulated timelines.

Applications for new awards that had already been reviewed by NIH’s study sections and advisory councils must receive decisions by January 12, 2026. Applications that are not that far along must receive decisions by mid-April or late July.

NIH also confirmed it would still award grants for Fiscal Year 2025 applications, even though that fiscal year ended September 30, 2025.

The agreement confirms that the close of the Federal Fiscal Year 2025 will not prevent the NIH from reviewing or awarding any applications.

Key Takeaway: The December 2025 agreement gave researchers court-enforced deadlines. NIH must act on stalled applications by defined dates, regardless of political preferences.

First Circuit NIH Appeal: January 2026

The bigger legal fight continued into 2026. The Trump administration appealed Judge Young’s June ruling, sending the core constitutional questions to the U.S. Court of Appeals for the First Circuit.

On January 6, 2026, oral argument was held before the First Circuit in the lawsuit challenging NIH’s mass termination of research grants on topics and populations disfavored by the Trump administration.

Plaintiffs urged the First Circuit to uphold the district court’s judgment that NIH relied on unlawful directives to abruptly terminate hundreds of research grants without engaging in the reasoned decision-making and explanation required by federal law.

The jurisdictional question from the Supreme Court’s August ruling was front and center. The plaintiffs argued the district court did have authority to hear the case.

“NIH’s reckless actions threaten to undermine decades of scientific progress, disrupt critical research on health disparities, and compromise public health outcomes. These terminations were not grounded in science but driven by political ideology,” said Rachel Meeropol of the ACLU’s Racial Justice Program.

The First Circuit’s ruling, expected in 2026, will determine whether Judge Young’s original order stands, and whether district courts can hear future grant termination challenges under the APA.

Will NIH Reinstate Canceled Grants?

This is the question every affected researcher is asking. The honest answer: some already have been, others remain uncertain.

STAT reported that the NIH had restored more than 2,000 terminated grants following Young’s June ruling, and it didn’t reverse course after the Supreme Court decision.

That’s meaningful. Even after the Supreme Court’s partial stay, the NIH did not re-terminate most of the grants it had already restored.

Going forward, projects will likely still be subjected to heightened scrutiny over their alignment with the administration’s policies.

For researchers whose applications were frozen rather than terminated, the December 2025 settlement provides a clearer answer. Applications must be reviewed on their scientific merit using standard NIH peer review processes.

How Researchers Can Challenge an NIH Grant Termination

Researchers who want to fight a terminated grant now face a more complicated legal path than before. The Supreme Court’s August 2025 ruling changed the game.

The decision effectively means individual grant termination decisions must be challenged on contractual grounds under the Tucker Act in the U.S. Court of Federal Claims.

Think of it like this: district courts handle administrative law challenges. The Court of Federal Claims handles contract disputes. The Supreme Court said grant terminations are a contract issue, not just an administrative one.

Practically, what this means for researchers:

• File challenges in the U.S. Court of Federal Claims, not federal district court
• Use the Tucker Act as the legal vehicle
• Argue that the termination breached the terms of the grant agreement
• Document all financial losses and research disruptions

All hope may not be lost for contractors and grantees whose funding has been canceled. Courts considering challenges to DEI-related directives have issued preliminary injunctions barring federal agencies from terminating funding for certain DEI programs pending merits hearings.

Getting an attorney familiar with federal contract and grant law is essential.

NIH DEI Grant Cuts and the Administrative Procedure Act

The APA is the legal backbone of both lawsuits. Understanding why it matters explains why the plaintiffs had such a strong case initially.

The APA requires federal agencies to follow a basic rule when making decisions: explain your reasoning. You cannot simply cancel something and say “agency priorities” with no further detail.

The plaintiffs asserted five counts under the Administrative Procedure Act, arguing that the New Directives and terminations were arbitrary and capricious, not in accordance with the law, exceeded statutory authority, were contrary to a constitutional right under the Fifth Amendment, and that NIH unlawfully withheld or unreasonably delayed acting on grant applications it stopped considering.

Judge Young agreed on the APA counts. He commented that the explanations in the directives and terminations in the administrative record were conclusory and bereft of reasoning in their entirety, and that the defendants had failed to consider the reliance interests of researchers, institutions, and the public in NIH-funded research.

The Supreme Court did not reverse that finding. It raised a jurisdiction question instead.

The APA argument remains intact as the First Circuit considers the appeal. If the First Circuit upholds district court jurisdiction, the APA violations finding could carry serious long-term consequences for how federal agencies handle grant terminations.

Key Takeaway: The Supreme Court’s August 2025 stay did not say the terminations were lawful. It raised a separate procedural question about which court has authority, leaving the APA violation finding untouched.

NIH Grants Lawsuit Timeline: 2025 to 2026

Here is the full case history in one place. No other source has put every key date in a single table.

What Researchers Affected by NIH Cuts Should Do Now

If your grant was terminated or your application was frozen, the path forward depends on where your case falls.

If your application was frozen, denied, or withdrawn: The December 2025 settlement applies. NIH must review your application using standard scientific review processes. Deadlines are set by court order. Track your review status and document everything.

If your grant was terminated (active, already funded): Challenges to individual grant terminations should be filed in the U.S. Court of Federal Claims under the Tucker Act. Contact an attorney experienced in federal contract law. Maintain records of all financial losses, lost personnel, and disrupted data.

For everyone:

• Monitor the First Circuit’s ruling. If the appeals court upholds district court jurisdiction, a broader class of terminated grants may be eligible for reinstatement.
• Track your institution’s response. Many research universities have their own legal teams monitoring this litigation.
• Be aware that even if grants are reinstated, researchers have lost biological samples, study participants, and key lab personnel since the grants were terminated. Document these losses for potential future claims.

Frequently Asked Questions

What is the NIH grants termination lawsuit?

The NIH grants termination lawsuit is a federal legal challenge to the Trump administration’s 2025 decision to cancel thousands of active research grants. Plaintiffs argue the cancellations violated the Administrative Procedure Act, the separation of powers, and statutory mandates from Congress. The lead case is APHA v. NIH, filed April 2, 2025, in the U.S. District Court for the District of Massachusetts.

How many NIH grants were terminated?

NIH terminated more than 2,600 research grants totaling approximately $8.9 billion under the Trump administration’s 2025 directives. The core lawsuits directly addressed roughly 800 to 900 grants worth about $780 million to $800 million. Grants covering health disparities, LGBTQ+ health, transgender health, vaccine hesitancy, and workforce diversity were most heavily targeted.

What did Judge William Young rule in the NIH lawsuit?

On June 16, 2025, Judge Young ruled the NIH grant terminations were unlawful, arbitrary and capricious, and “void and illegal.” He ordered NIH to immediately reinstate the terminated grants covered by the two lawsuits. He also stated he had not seen government racial discrimination of this kind in 40 years on the federal bench.

Did the Supreme Court reverse the ruling against NIH?

The Supreme Court issued a 5 to 4 stay on August 21, 2025, allowing NIH to pause grant payments while the appeal proceeds. The Court did not rule the terminations were legal. Instead, it raised a jurisdictional question about whether district courts can hear these challenges. Justice Barrett wrote that grant termination challenges likely belong in the U.S. Court of Federal Claims under the Tucker Act.

What is the current status of the NIH grants lawsuit in 2026?

On December 29, 2025, NIH reached a settlement requiring it to review frozen and denied grant applications using standard scientific review processes. The First Circuit Court of Appeals heard oral arguments on January 6, 2026, on the core appeal of Judge Young’s ruling. A ruling from the First Circuit is expected in 2026 and will determine whether district courts can hear APA challenges to federal grant terminations.

Where This Case Goes From Here

The NIH grants termination lawsuit is not over. The December 2025 settlement helped researchers with stalled applications. But nearly 850 terminated grants remain unresolved, and the First Circuit’s ruling will shape how all future grant termination challenges are handled.

If you are an affected researcher, take action now. Verify your application is in the review queue per the settlement. If you had an active grant terminated, talk to a federal contract attorney about the Court of Federal Claims pathway.

The science does not stop just because the politics got complicated. Keep your documentation, follow the court calendar, and know that the legal fight is still very much alive.
