Supreme Court Power Plays: Landmark Rulings Reshape Presidential Authority and Election Law

Between June 25 and June 29, 2026, the Supreme Court handed down decisions that didn't just settle individual cases—they rewrote the constitutional rules governing whom the president can deport, whom he can fire, and how far his power extends over the institutions meant to check it. Three major rulings expanded executive authority over immigration policy, asylum access, and independent federal agencies, arriving at the same moment the Trump administration announced plans to deport more than 500 unaccompanied children and moved to control who can register to vote. These aren't isolated legal questions. They're a systematic shift in the balance of power that determines who can enter the country, who runs the agencies that regulate daily American life, and ultimately who gets to participate in democracy.

Concrete Rulings: Sweeping Authority Over Immigration and Asylum

On June 25, the Court issued two 6-3 immigration rulings—Mullin v. Doe and Mullin v. Al Otro Lado—that together expand executive power over Temporary Protected Status and asylum while sharply limiting judicial review.

In Mullin v. Doe, the Court held that the TPS statute bars judicial review of non-constitutional claims challenging the Trump administration's termination of TPS for Haitian and Syrian nationals—approximately 350,000 Haitians and 6,000 Syrians who had been living and working legally in the United States.

Justice Samuel Alito wrote in the majority opinion that "the statutory phrase barring judicial review of any determination related to a TPS designation is clear and very broad, covering both individual decisions and the process leading to them."

Lower courts had previously found the Secretary likely acted arbitrarily and capriciously in terminating TPS by ignoring evidence of Haiti's true country conditions and failing to consult other agencies, with suggestions of racial animus in statements by President Trump and Secretary Noem—but the Supreme Court concluded that the Haitian plaintiffs' equal protection claim was unlikely to succeed.

In the companion case Mullin v. Al Otro Lado, the Court held that asylum seekers waiting on the Mexican side of ports of entry have not legally "arrived" in the United States and can be turned away under the metering policy, significantly restricting access to the asylum process at the southern border. The metering policy, originally started in 2016 under the Obama administration and expanded by Trump, was abolished by the Biden administration in 2024, but the ruling clears the legal path for its return. Thousands of asylum seekers were previously turned away under the policy, forced to live in squalid conditions in Mexico and vulnerable to cartel violence.

White House spokesperson Abigail Jackson stated that "the Supreme Court validated President Trump's long-held belief that temporary protected status is, by its very nature, temporary," calling the rulings a major victory for American sovereignty. Trump adviser Stephen Miller called the asylum ruling a victory and stated that "America's doors are closed fully to asylum seekers," signaling that ending birthright citizenship for children of migrants is an intended next step.

Human Stakes: Immediate Danger for Vulnerable Populations

The TPS ruling places protections for roughly 1.3 million people from 17 countries currently enrolled in TPS at risk, as courts cannot review most TPS terminations under this precedent. The ACLU of Northern California warned that "the Court's TPS ruling paves the way for the Trump administration to strip legal status and work authorization from more than 1.3 million people."

Carol Rose, executive director of ACLU of Massachusetts, called the ruling "devastating for Haitian and Syrian communities," stating that "the role of racism in TPS revocation is undeniable, and affected individuals still have due-process rights which the ACLU pledges to defend."

More than 500 unaccompanied immigrant children who have been in federal custody for at least six months without eligible U.S. sponsors are now slated for deportation, with the administration using a facility near deportation flights in Alexandria, Louisiana, as part of infrastructure being repurposed to support rapid removal operations.

Senator Ron Wyden condemned the plan as "a severe institutional failure that weaponizes the agency charged with their protection," warning that federal child-welfare infrastructure is being repurposed to support rapid removal operations.

Justice Sonia Sotomayor warned in her dissent in Mullin v. Al Otro Lado that "the majority's interpretation permits the Government to [turn people back] even if the refugees complied with all applicable laws and regulations, even if the port had ample capacity to inspect them, and even if turning them back would result in the very persecution from which they narrowly escaped. The consequences of today's decision are predictable. More people will die." She read portions of her dissent from the bench—a rare sign of strenuous objection—and the dissent was twice the length of the majority opinion.

Lead attorneys for asylum seekers Geoff Pipoly and Andy Tauber stated that "this decision would directly lead to thousands of innocent individuals facing violent, unnecessary deaths."

Justice Ketanji Brown Jackson filed a separate dissent, criticizing the majority for "reasoning drawn from metaphors about a linebacker and a houseguest and a piece of mail" rather than engaging with facts about the defunct metering policy, warning that "no one knows how, if at all, the reasoning drawn from these metaphors will map on to the realities of a future metering policy."

Connecting Immigration Rulings to Election Law

Even as the Supreme Court expanded presidential power over immigration, the Trump administration made simultaneous moves to reshape who can vote through executive directives on voter eligibility verification.

U.S. District Court Judge Indira Talwani in Massachusetts found major parts of Trump's March 2026 executive order on voter citizenship lists legally void, permanently blocking the administration from implementing its directive to create Confirmed Citizen Lists of eligible voters in 23 states and the District of Columbia. Judge Talwani ruled that "the Constitution reserves the power to determine voter eligibility to the States alone. Neither the Executive Branch nor Congress may interfere with this power."

A separate federal judge in Boston, Judge Denise Casper, also permanently barred Trump's requirement for documentary proof of citizenship when registering to vote, converting a prior preliminary injunction into a permanent block and finding the directives infringed upon the separation of powers and state authority over elections.

These voting rights blocks represent rare successful judicial pushback against executive overreach, even as the Supreme Court's immigration rulings signal a permissive approach to presidential authority in adjacent domains.

The Larger Pattern: Systematic Concentration of Executive Authority

On June 29, the Supreme Court issued another 6-3 ruling in Trump v. Slaughter that significantly expands President Trump's power to fire leaders of independent federal agencies like the Federal Trade Commission, overruling Humphrey's Executor, a longstanding precedent that had limited presidential removal power.

Chief Justice John Roberts wrote the majority opinion, arguing that "subordinates who exercise the President's power are subject to removal by him. Then, and only then, can they remain accountable to the President, and the President to the people." Roberts continued: "Although it is up to the Senate to decide whether to confirm those with whom the President would prefer to work, neither Congress nor the courts may saddle him with those with whom he cannot work."

Justice Sotomayor read a summary of her dissent from the bench, writing that "the Court gives the President a power unknown even to the English Crown against which the Founders revolted, elevating him above his once-coequal branches by transforming a duty to take care that the laws be faithfully executed into a license to act in defiance of those very laws." She continued: "Put simply, today the majority reshapes our Government. Dozens of independent commissions are now likely to become purely executive agencies, shifting tremendous power over broad swaths of American life into the President's hands." And concluded: "Perhaps worst of all, the Court today forgets its place."

In a separate Trump v. Cook decision the same day, the Court carved out an exception for the Federal Reserve by preventing Trump from removing Governor Lisa Cook, reaffirming the central bank's unique degree of independence.

What Checks Remain: Vigilance Without Despair

The federal court blocks on Trump's voting directives in 23 states and the District of Columbia demonstrate that lower courts retain some capacity to check executive overreach. The carve-out for the Federal Reserve shows that even the conservative Supreme Court majority recognizes some institutional boundaries, preserving independence for the central bank while dismantling it elsewhere.

Civil rights organizations including state ACLU chapters have pledged to continue defending due-process rights for TPS holders and other affected immigrants, shifting litigation strategy from challenging executive authority to enforcing remaining procedural protections. Congressional authority remains a potential check, though senators like Ron Wyden who condemned the deportation of unaccompanied children have not yet advanced legislation to constrain the administration's expanded powers.

Miller's signals that ending birthright citizenship is the next target indicate the executive branch views these Supreme Court victories as permission to press further, testing the outer limits of newly confirmed presidential authority.

Together, the rulings represent a constitutional inflection point: removing judicial review over immigration policy, enabling the president to fire independent agency heads at will, and attempting—though blocked by lower courts—to federalize control over voter eligibility. For the 1.3 million TPS holders, the hundreds of unaccompanied children facing deportation, and the asylum seekers who may be turned away at the border, the window for effective resistance is narrow—but the lower court victories on voting rights suggest that determined legal challenges, public pressure, and institutional friction can still slow the consolidation of executive power.
