The Trump administration’s sweeping effort to reorganize the federal government, including massive layoffs and a reduction of the Department of Health and Human Services (HHS), has been halted following a preliminary injunction issued by U.S. District Judge Susan Illston in California. In her decision, Judge Illston stated that neither the President nor department agency heads possess the authority to unilaterally restructure the federal government without Congress's approval.
In the 51-page opinion released late Thursday, Judge Illston asserted, "Congress creates federal agencies, funds them, and gives them duties that—by statute—they must carry out. Agencies may not conduct large-scale reorganizations and reductions in force in blatant disregard of Congress’s mandates, and a president may not initiate large-scale executive branch reorganization without partnering with Congress."
The injunction indefinitely blocks the administration's plans to consolidate HHS divisions from 28 to 15 and terminate up to 10,000 federal employees. The case was brought by public sector unions, nonprofits, and multiple local governments against President Donald Trump, HHS Secretary Robert F. Kennedy Jr., and other federal officials.
The judge’s decision builds upon a temporary restraining order she issued on May 9, which would have expired on May 23. This new ruling extends the hold and restricts the federal government from implementing new reorganization plans or additional reductions in force (RIFs) while the legal challenge proceeds. Plaintiffs include the American Federation of Government Employees, the American Public Health Association, and the cities of Baltimore, Chicago, and San Francisco.
The core of their argument centers on the claim that the February 11 executive order attempting to overhaul the federal bureaucracy violates constitutional principles, specifically the separation of powers. According to their lawsuit, “The president does not possess authority to reorganize, downsize or otherwise transform the agencies of the federal government, unless and until Congress authorizes such action.”
Judge Illston highlighted that the scale of proposed layoffs threatens the statutory missions of various agencies. Notably, the National Institute for Occupational Safety and Health's Pittsburgh office faced 221 cuts out of 222 staff, effectively eliminating its presence. In San Francisco, the closure of the Head Start program's office forced local governments to lay off over 100 early childhood educators.
“The court is not convinced that a directive to respect statutory mandates is a message the agencies have actually received,” Illston noted. "It appears the Department of Health and Human Services is planning to practically wipe out the National Institute for Occupational Safety and Health, an office established by Congress."
Other affected programs include those that maintain the federal poverty guidelines, determine Medicaid eligibility, manage mental health and substance abuse services, and track infectious diseases. Additionally, the World Trade Center Health Program and tobacco prevention initiatives have also faced disruption.
The Trump administration has since filed an emergency appeal to the U.S. Supreme Court, seeking permission to resume its reorganization efforts. According to administration attorneys, the injunction imposes "universal relief that far exceeds anything necessary." They argue that the President holds broad authority to manage the executive branch and cited previous administrations, including President Bill Clinton’s, which conducted similar reductions in force.
The administration also requested the court to reconsider its directive to disclose sensitive agency plans, describing the required documents as “significant, highly sensitive information.”
Public health leaders and elected officials continue to express concern over the restructuring efforts. New York Attorney General Letitia James commented, “This administration is not streamlining the federal government; they are sabotaging it and all of us.” She emphasized that the layoffs could imperil national health and safety by eliminating critical personnel and services.
The broader implications of this legal challenge touch on the limits of executive power and the role of Congress in overseeing federal operations. As additional filings are expected from both sides in the coming weeks, the case is poised to set a precedent on the legality of unilateral executive branch restructuring.
Recent polling by the Kaiser Family Foundation (KFF) indicates that 60% of Americans oppose significant staffing and budget cuts to federal health agencies. While Republican voters tend to support the administration's overall actions, even a majority within that group oppose cuts to programs targeting infectious disease tracking, Medicaid, Medicare, and mental health services.
If approved, further budget proposals supported by the Trump administration may lead to deeper cuts—such as the elimination of 83,000 jobs at the Department of Veterans Affairs. A leaked budget suggests the HHS alone could face a $40 billion reduction.
