The Supreme Court Lets Lisa Cook Keep Her Fed Seat Without Deciding Whether Trump Can Fire Her

Why Lisa Cook keeps her seat, for now

On June 29, 2026, the Supreme Court refused to let President Trump remove Lisa Cook from the Federal Reserve's Board of Governors while her case proceeds. The vote was 5-4. It was the first time in the Federal Reserve's 111-year history that a President had even attempted to fire a sitting Governor, and the order leaves that attempt paused.¹

The majority rested its order on procedure, not on power. Cook was entitled to "some explanation of the evidence at issue, some avenue for a response, and a deadline by which a response would be due" before her removal took effect. Because the President gave her none of that, the Court held, her firing was "erroneous and void" from the moment it issued.¹ On the separate question of what "cause" itself requires, the Court rejected both parties' readings. The government's, that almost any complaint about a Governor would do, failed. So did Cook's, that only conduct committed in office could count. In place of either, the Court gave only an instruction: "any definition of 'cause' in this context must reflect the Federal Reserve's unique historical status and role," which "counsels a substantial threshold."¹ Justice Kavanaugh, concurring, said plainly what the ruling left undone: it "does not decide whether the President may lawfully remove Governor Cook for cause."¹

The stay denial did not arrive alone. The same morning, a 6-3 majority in Trump v. Slaughter overruled Humphrey's Executor v. United States outright for the Federal Trade Commission: "If anything more is left of Humphrey's, we overrule it."² In the same breath, the Court carved the Federal Reserve out of that holding by name, citing "the Federal Reserve, to the extent that it follows in the tradition of the First and Second Banks of the United States" as an entity Humphrey's collapse does not reach.² That language traces to a footnote the Court had used a year earlier to stay the reinstatement of two other agencies' board members, describing the Fed as "a uniquely structured, quasi-private entity that follows in the distinct historical tradition of the First and Second Banks of the United States."³ The government itself never asked the Court to go further in Cook's case. At argument, its own counsel "acknowledge[d]" that description of the Fed and conceded the administration had "not challenged... the removal restriction in this case."¹

What actually happened, in order, is easy to lose inside the doctrine it reopened:

1. Aug. 25, 2025

   The removal letter⁴

   Trump tells Cook he lacks "confidence in [her] integrity" and cites conflicting owner-occupancy statements on a $203,000 Michigan mortgage from June 2021 and a $540,000 Georgia mortgage two weeks later, both attested as her "primary residence" for the year that followed.

2. Sept. 9, 2025

   A preliminary injunction⁵

   The district court blocks the removal, holding that "for cause" does not reach conduct that predated Cook's time in office and that she was owed a pre-deprivation hearing.

3. Sept. 15, 2025

   The D.C. Circuit declines to stay it¹

   A divided panel leaves the injunction in place; Judge Katsas dissents, arguing Cook has no property interest in her seat.

4. Jan. 21, 2026

   Oral argument¹

   The government tells the Justices it is not contesting the constitutionality of the for-cause restriction itself, only its application here.

5. June 29, 2026

   The stay is denied, 5-4¹²

   Cook keeps her seat while the case returns to the district court. Hours earlier, Slaughter overruled Humphrey's Executor for the FTC.

As one law firm's client alert, written by lawyers with no role in the case, summarized it the same day: "The decision addresses only the preliminary injunction standard. The underlying question of whether Cook's actual removal was legally justified remains unresolved pending conclusion of full litigation."⁶ Two questions remain genuinely open and genuinely contested. One: what showing satisfies "cause" under the statute. Two: whether the Federal Reserve's structure keeps it inside the sliver of Humphrey's Executor that survived Slaughter, or places it outside that sliver like every other independent commission. Both sides argue from the same body of law.

Inside or outside Humphrey's Executor's surviving core

Both sides agree the Federal Reserve wields real power. What divides them is where its structure sits: inside the sliver of Humphrey's Executor that survived Slaughter, or outside it, like the FTC. That is an unsettled question of law, an undecided fact rather than a clash of values, and no court has ruled on it, because the government never asked the Cook courts to.¹ It becomes a forecast only once litigation resumes on remand, and there is already a paper trail showing how thin the ground under either answer is.

The "distinct historical tradition" language both opinions lean on has a short pedigree. It originates in a footnote to Seila Law, answering a dissent's argument that the Consumer Financial Protection Bureau resembled older financial regulators: "even assuming financial institutions like the Second Bank and the Federal Reserve can claim a special historical status, the CFPB is in an entirely different league."¹² Justice Kagan's Wilcox dissent read that sentence for exactly what it was built to do: "footnote 8 provides no support... an assumption made to humor a dissent gets turned into some kind of holding."³ Justice Sotomayor's Slaughter dissent presses the same complaint from the opposite direction, asking how a Court that just discarded "ad hoc historical exceptions" everywhere else can keep one for the Fed: "How close is close enough for a historical analogue of this kind? Does any agency that 'influence[s] monetary policy' qualify?... What happens if Congress adds new functions beyond the historical baseline?" She points to the Fed's own civil-penalty authority, up to $1 million per day, as evidence that baseline keeps growing.² Four Justices, across two opinions a year apart, are saying the same thing about the sentence Cook and Slaughter now lean on: it was never built to carry this weight.

Independent legal scholarship, working from opposite starting points, converges on a related but distinct complaint: not that the carve-out reaches the wrong result, but that no one has yet supplied it a stable doctrinal line. Bamzai and Nielson's own reading of current precedent favors the removal camp, yet they conclude that only Congress, by stripping the Fed of regulatory functions that are "inherently executive," could put the Fed's monetary independence on secure footing going forward.⁹ Columbia's Lev Menand, writing from a position sympathetic to central-bank independence, reviewed the scholarly proposals for a principled Fed exception and "concludes that none are tenable," leaving the protection resting on "stare decisis," precedent kept for precedent's sake rather than for a reason a lower court could apply.¹³ Neither scholar is deciding who has the better constitutional argument. Both are describing the same gap: an exception the Court keeps citing and has not yet been made to defend.

One distinction is easy to lose inside that gap. The district court that first blocked Cook's removal held categorically that "for cause" "does not contemplate removing an individual purely for conduct that occurred before they began in office," meaning her mortgage filings, which predated her appointment, could never count.⁵ The Supreme Court did not adopt that theory. Justice Alito's dissent notes that "the majority and Justice Thomas apparently agree" the district court's categorical rule was wrong; the stay was denied on due process instead, leaving the seriousness-and-nexus standard above as the actual governing test.¹ Whether Cook's 2021 mortgage filings meet that standard is a question no court has answered yet. A second distinction sits beneath the first. Thomas treats Cook's office as never having been "property" the Constitution protects; the majority instead held her removal "erroneous and void" for want of due process.¹ Neither statement is the question Collins v. Yellen already settled for a different removable officer: an unconstitutional removal restriction does not make an official's actions void from the start, though it can leave the government owing "compensable harm" for what happened while the restriction stood.¹⁴ Removal validity and the downstream validity of what a removed, or wrongly retained, official does are two different questions, and only one of them was before the Court in June.

What would resolve the larger question is a merits ruling the district court has not yet issued. It would have to weigh facts no opinion so far has reached: Cook's specific conduct, and the specific authority Congress has since added to the Board. The Congressional Research Service published its own summary of where things stand a week after the decision. The Court "rejected both the government's broad reading" of cause "and Cook's narrow one," it noted, landing on the substantial-threshold test while declining to "fully demarcate the contours" of what "cause" means, since the ultimate question of removing Cook "will depend on the adjudication of those facts in the lower courts."¹⁵ Neither the district court nor the Supreme Court has yet answered that question, or the structural one behind it. Until one of them does, the strongest form of each side's case rests exactly where it stands today: an Article II claim unnarrowed since Slaughter, against a 111-year-old statute the Court says still means what it says.
