The U.S. Supreme Court issued a series of consequential decisions Monday that touched on election law, the independence of the Federal Reserve, digital privacy, and the scope of presidential authority over federal agencies, marking one of the most significant single days for the court this term. For conservatives, the biggest victory came in the court’s
In a 6-3 ruling along ideological lines, the court held that the president has the authority to fire leaders of independent federal agencies and commissions, overturning the nearly century-old precedent known as Humphrey’s Executor v. United States.
That 1935 ruling had allowed Congress to shield certain independent agency leaders from being removed by the president without cause, creating a powerful class of unelected officials who could exercise executive authority while remaining largely insulated from direct democratic accountability.
The case centered on Rebecca Kelly Slaughter, a commissioner at the Federal Trade Commission whom President Trump fired last year despite a federal law requiring presidents to show cause, such as malfeasance, before removing FTC commissioners.
Trump argued that as head of the executive branch, he must have authority to control the leadership of agencies carrying out executive power, and that laws preventing him from removing those officials violate the Constitution’s separation of powers.
The court’s conservative majority agreed, delivering one of the most significant structural victories for presidential authority in decades and striking a major blow against the permanent administrative state that has grown far beyond what the founders envisioned.
Slaughter reacted angrily after the ruling, warning that presidents could now reward allies and punish perceived enemies without meaningful checks.
But conservatives saw the decision differently: as a long-overdue correction to a system in which agency officials exercise enormous power over the American people while claiming independence from the president voters actually elected.
Slaughter also contrasted her loss with the court’s separate ruling involving the Federal Reserve, arguing that financial regulators received special protection while agencies focused on consumer protection did not.
That contrast was on full display in the second major ruling of the day.
In a narrower 5-4 decision, the Supreme Court ruled that President Trump cannot remove Federal Reserve Governor Lisa Cook, at least for now.
Cook, a Biden appointee and the first Black woman to serve on the Federal Reserve’s board of governors, had been targeted for removal after Bill Pulte, director of the Federal Housing Finance Agency, accused her of mortgage fraud.
Pulte’s allegations, first made public in August 2025, claimed that Cook took out mortgage loans in 2021 on properties in Ann Arbor, Michigan and Atlanta, Georgia, and improperly listed both as primary residences in order to receive tax exemptions on each.
Cook has denied wrongdoing and described the allegations as manufactured, while the Trump administration opened a criminal investigation and attempted to remove her from the Federal Reserve board for cause.
A lower court blocked that removal in September, and the administration appealed the matter to the Supreme Court.
In Monday’s ruling, the justices did not decide the broader constitutional question of whether a president has authority to remove sitting Federal Reserve governors.
Instead, the court rested its decision on procedural grounds, finding that the administration had not provided Cook with the due process protections required before removal could occur.
The practical effect is that Cook remains on the Federal Reserve board for now, though the door remains open for the administration to pursue her removal again if it follows the procedure the court outlined.
For conservatives, the ruling was a temporary setback rather than a total defeat, since the court did not permanently foreclose presidential authority over Federal Reserve officials.
Legal analysts said the court appeared to draw a distinction between the Federal Reserve and other independent agencies, recognizing that markets place a premium on central bank stability while still leaving unresolved the deeper constitutional fight over who ultimately controls the executive branch.
The third major ruling of the day involved mail-in ballots, where the court delivered a frustrating defeat for Republicans by upholding a Mississippi law allowing election officials to count mail-in ballots postmarked by Election Day but received up to five days afterward.
The decision preserves so-called grace period laws that exist in eighteen states and territories, including Republican-led Mississippi, though many of the largest jurisdictions with such laws are Democratic-led states such as California, Illinois, and New York.
President Trump, who has long warned that mass mail-in voting is vulnerable to fraud, abuse, and public distrust, called the ruling “a little bit surprising” and said it underscored the urgency of passing the SAVE America Act.
Speaking from the Oval Office, Trump said the decision was “very detrimental to honest elections” but acknowledged that the court had largely preserved the existing legal landscape rather than imposing a nationwide rule from the bench.
Trump renewed his call for the Senate to eliminate the filibuster in order to pass the SAVE America Act, a sweeping federal election integrity bill that would impose strict voter identification requirements and limit the use of mail ballots nationwide.
He also floated the possibility of attaching the election overhaul to a budget reconciliation package, which could allow Senate Republicans to pass it on a party-line vote without needing Democratic support, though any such move would still need to clear the Senate parliamentarian.
Voting rights groups celebrated the mail ballot ruling, arguing that extended receipt windows help rural voters, overseas voters, and members of the military whose ballots may be delayed in the mail.
But conservatives countered that election rules should prioritize certainty, transparency, and same-day finality wherever possible, especially after years of public distrust created by loose mail-ballot systems and inconsistent state procedures.
Not every election-related matter favored Democrats on Monday, and the court also issued a major digital privacy ruling that cut across ideological lines.
In a 6-3 decision, the justices ruled that the use of so-called geofence warrants, which capture location data from cell phones in a targeted area, constitutes a search under the Fourth Amendment.
Justice Elena Kagan wrote for the majority in a decision that drew support from both conservative and liberal justices, while three conservative justices dissented.
The ruling will require law enforcement to obtain a warrant before accessing such location data in future investigations, a decision privacy advocates praised as an important check on government surveillance in the digital age.
In addition to the major agency, election, and privacy rulings, the court declined to hear President Trump’s appeal in the E. Jean Carroll defamation case, meaning Trump must pay the former columnist five million dollars as ordered by a lower court.
The justices also rejected a defamation appeal brought by attorney Alan Dershowitz against CNN, leaving a lower court ruling against him intact.
Monday’s rulings came shortly after another major Supreme Court victory for the Trump administration, in which the justices backed the government’s move to end Temporary Protected Status for roughly 350,000 Haitian immigrants and 6,000 Syrian immigrants living in the United States.
In that 6-3 ruling, the court held that the Department of Homeland Security’s decision to end the protections was not subject to judicial review, reinforcing the executive branch’s authority over immigration enforcement decisions.
Taken together, the decisions mark a mixed but highly consequential day for the Trump administration.
The agency-firing ruling stands as a generational victory over the administrative state, restoring the principle that executive power must remain accountable to the president and, through him, to the voters.
The Federal Reserve ruling, while narrower and less favorable to Trump, leaves room for future action if the administration follows the proper process.
The mail-in ballot ruling is a setback for Republicans seeking tighter election procedures through the courts, but it also makes clear that the real fight over election integrity now belongs in Congress, where the SAVE America Act remains the most important vehicle for nationwide reform.
Legal scholars say the cumulative effect of Monday’s decisions will be felt for years, especially the overturning of Humphrey’s Executor, which is expected to trigger new litigation over the limits of presidential removal power.
Several agency heads who once relied on statutory protections to shield them from political accountability may now find their positions far less secure, regardless of which party controls the White House in future administrations.
