Supreme Court Rulings on Presidential Power and Trump Cases: A Rather Predictable Expansion of Executive Authority

The Supreme Court, in a series of recent decisions, has significantly recalibrated the intricate balance of power concerning the executive branch and independent agencies, alongside addressing several high-profile cases involving former President Trump. These Supreme Court rulings on presidential power and Trump cases arrived with the usual fanfare, or lack thereof, depending on one’s partisan leanings.

The Unitary Executive Theory Triumphs: Independent Agencies, No Longer So Independent

A landmark 6-3 decision, *Trump v. Slaughter*, irrevocably altered the landscape of federal agency governance. The Court held that Congress cannot restrict the President’s power to remove members of so-called independent executive agencies at will, effectively overturning the 90-year-old precedent established in *Humphrey’s Executor v. United States* (1935). This ruling, issued June 29, 2026, consolidates executive control over entities previously considered insulated from direct political pressure.

Chief Justice John Roberts, writing for the majority, articulated a clear constitutional mandate. He posited that the Constitution vests all executive power in a single President, requiring officers who exercise executive authority to remain accountable to that office. Subordinates, therefore, must be removable by the President for true accountability to exist.

The case originated from President Trump’s March 2025 dismissal of Federal Trade Commission (FTC) Commissioner Rebecca Slaughter. Her termination lacked the statutory “inefficiency, neglect of duty, or malfeasance in office” justification, relying instead on the President’s Article II authority, citing policy disagreements. The district court, applying *Humphrey’s Executor*, initially ordered Slaughter’s reinstatement. The Supreme Court reversed this.

The FTC, a multi-member body, has historically engaged in significant executive functions. These include promulgating substantive rules with the force of law, conducting investigations, initiating enforcement actions, and adjudicating disputes. The Court deemed these functions indisputably “executive” in nature.

Justice Sonia Sotomayor, in a dissenting opinion, expressed profound disappointment. She warned of a “massive expansion of executive power,” suggesting the decision reshapes the government in ways the founders never intended. Dozens of independent commissions, she argued, could now become purely executive agencies, shifting immense power into the President’s hands.

This Supreme Court expands presidential power over independent agencies, certainly. It essentially means that presidents now have broader authority to reshape the leadership and, by extension, the policy direction of formerly independent agencies. Political meddling into objective decision-making, a long-standing concern, is now considerably more viable.

The Federal Reserve: An Exception to the Rule, Apparently

Curiously, on the very same day, the Court issued a separate 5-4 decision in *Trump v. Cook*, declining to permit President Trump to remove Federal Reserve Governor Lisa Cook. This ruling provided a peculiar carve-out, preserving the Federal Reserve’s long-standing independence.

Chief Justice Roberts, again writing for the majority, cited the Fed’s “unique historical status and role.” This distinction suggests that monetary policy, unlike consumer protection or environmental regulation, benefits from insulation from direct political interference. The decision left a lower court order in place, preventing Cook’s removal while litigation proceeds.

The rationale focused on Congress’s intent to maintain an independent central bank. The Court found that allowing at-will presidential removal of Fed governors would fundamentally impede that independence. This bifurcated outcome highlights a nuanced, if somewhat contradictory, approach to executive power.

Trump’s Legal Docket: More Than Just Presidential Prerogative

Beyond the executive power discussions, the Supreme Court also addressed other aspects of the extensive Trump legal portfolio. The Court declined to hear Trump’s appeal in the civil case brought by E. Jean Carroll. This decision leaves intact the $5 million jury verdict against him for sexual abuse and defamation.

This particular non-action by the Court marks another loss in a protracted seven-year legal battle. Trump still faces an $83.3 million defamation judgment, with appeals ongoing. He continues to assert “absolute immunity” for comments made during his presidency in that context.

In a related electoral matter, the Court upheld a Mississippi law concerning mail-in ballots. The law permits ballots postmarked by Election Day to be counted up to five business days afterward. This ruling dealt a blow to Trump’s persistent efforts to restrict mail-in voting.

Earlier, in July 2024, the Supreme Court in *Trump v. United States* had already established a precedent concerning presidential immunity. That 6-3 decision granted a former president presumptive, if not absolute, immunity from criminal prosecution for official acts. Chief Justice Roberts, again for the majority, delineated categories of presidential actions, with core constitutional authority meriting absolute immunity.

Another recent case, *Mullin v. Doe*, decided June 25, 2026, involved challenges to the termination of Temporary Protected Status (TPS) for aliens from Syria and Haiti. President Trump was a petitioner, and the court noted statements suggesting racial animus against “Haitians and other nonwhite foreigners.” The Court held that the TPS statute bars judicial review of non-constitutional claims.

Reactions: A Chorus of Predictable Outrage and Celebration

Reactions to these rulings unfolded precisely as expected. President Trump, never one for understatement, hailed the *Slaughter* decision as a “BIG WIN” on Truth Social. He declared it the “Greatest Increase in Presidential Power in the last 100 years.” Such pronouncements typically follow any judicial outcome favoring executive authority.

Conversely, liberal justices and various advocacy groups expressed considerable dismay. Justice Sotomayor, reading a summary of her dissent from the bench, a rare occurrence, signaled strong disagreement. She warned the majority had “upended settled constitutional law” and replaced it with a “loyalty test.” This, she contended, “promises to unleash only chaos.”

Rebecca Slaughter herself stated she was “profoundly disappointed” by the decision. She articulated that the ruling represents a “massive expansion of executive power at the expense of Congress.” Labor advocates, unions, and consumer advocacy groups universally criticized the decision, citing long-term impacts on democracy.

Legal experts, as is their wont, offered varied interpretations. Some noted the culmination of a years-long weakening of New Deal-era precedents. Others emphasized the renewed focus on the “unitary executive” theory. The consistent chipping away at *Humphrey’s Executor* over recent years has finally reached its logical conclusion.

Future Implications: The Executive Branch, Unfettered?

The implications of these rulings are, to put it mildly, extensive. The decision fundamentally alters the constitutional foundation of modern administrative agencies. It will likely usher in major changes to the structure of the federal government.

Future presidents now possess substantially greater ability to reshape agency priorities. They can replace commissioners whose policy views diverge from the administration’s. This could lead to increased volatility in administrative policy across presidential administrations.

The rulings fulfill a major goal for many conservatives. They have long argued for nearly unfettered presidential authority over the executive branch. This aligns with the idea that the President, as the sole executive, must control those executing the laws.

Expect a new wave of litigation challenging removal protections throughout the federal government. Agencies previously considered independent, such as the Nuclear Regulatory Commission or the Federal Energy Regulatory Commission, may now face direct presidential oversight. The delicate balance of power, a theoretical construct more than a practical reality at times, has certainly shifted.
