The U.S. Supreme Court’s June 29 decision in Trump v. Slaughter looks set to fundamentally reshape presidential authority over independent federal agencies.
The case originated from President Donald Trump’s removal of Federal Trade Commission Commissioner Rebecca Slaughter, but its consequences reach far beyond the FTC.
The Court used the dispute to overrule Humphrey’s Executor v. United States, a 1935 precedent that had long allowed Congress to protect independent agency members from presidential removal except for cause.
In its place, the Court established that principal officers exercising executive power must, as a general rule, remain removable by the President at will.
The ruling dramatically expands presidential control over bodies that have historically operated with a significant degree of independence from the White House.
The decision carries particular weight for the National Labor Relations Board, whose own removal dispute has been working its way through the courts for over a year.
President Trump removed NLRB Member Gwynne Wilcox in January 2025, a move that sparked litigation after a district court reinstated her, relying heavily on Humphrey’s Executor as its legal foundation.
The Supreme Court had previously stayed that reinstatement order, and the Board only recently returned to a functioning quorum following White House nominations.
With Humphrey’s Executor now expressly overruled, the legal basis supporting Wilcox’s reinstatement has largely been swept away, making the eventual outcome of her case considerably more predictable.
The Merit Systems Protection Board and other independent agencies that relied on similar statutory for-cause removal protections now find themselves in equally uncertain legal territory.
For employers, the practical consequences of Trump v. Slaughter could be significant, as changes in NLRB composition, enforcement priorities, rulemaking, and litigation positions may now occur far earlier in any given presidential administration.
Incoming administrations will be able to replace agency leadership more swiftly than under the prior legal framework, accelerating shifts in the pace and direction of federal labour and employment enforcement.
The ruling represents one of the most consequential changes to the structure of the U.S. administrative state in nearly a century, with implications that will take time to fully materialise across the regulatory landscape.
