The Supreme Court handed down the final opinions of its 2025–2026 term on Tuesday, June 30, resolving four remaining cases out of 58 argued this term — decisions carrying profound consequences for the boundaries of executive authority, the constitutional guarantee of birthright citizenship, the mechanics of voting, and Americans’ digital privacy rights. The rulings arrive at a moment of intense scrutiny of a court whose conservative supermajority has already reshaped foundational legal protections this term, including what remained of the 1965 Voting Rights Act.
Two of the four decisions had already landed on June 29, with the court ruling 6–3 to dramatically expand presidential power over independent federal agencies and separately restricting law enforcement’s use of geofence warrants. The two remaining cases — on birthright citizenship and mail-in ballot rules in Mississippi — were still pending as of the term’s final day.
Presidential Removal Power: A Sweeping Win for the Executive Branch
In Trump v. Slaughter, the court ruled 6–3 in favor of the Trump administration, striking down the “for-cause” removal protection that had shielded commissioners of independent federal agencies from presidential firing. The case was brought by Rebecca Slaughter, a Democratic member of the Federal Trade Commission whose term runs through 2029, after President Trump removed her before it expired. In dismantling that protection, the majority overruled Humphrey’s Executor v. United States, a 91-year-old precedent that had long served as the legal foundation for Congress’s ability to insulate expert regulatory bodies — the FTC, the Securities and Exchange Commission, and others — from direct presidential control.
The practical stakes of this ruling extend far beyond the FTC. Independent agencies were designed by Congress as a structural check on concentrated executive power, staffed by commissioners whose fixed terms and removal protections were meant to insulate technical regulatory decisions from political interference. By eliminating those protections, the court’s conservative majority has handed the presidency a tool to subordinate the regulatory apparatus to White House priorities, regardless of congressional intent. In a partial counterweight, the court ruled 5–4 that Federal Reserve Board member Lisa Cook may remain in her position while her own legal challenge to Trump’s firing attempts proceeds through the courts — a narrow carve-out that does not undo the broader damage to agency independence.
Mail-In Ballots: A Rare Loss for Republican Litigants
In Watson v. Republican National Committee, the court upheld a Mississippi law allowing mail-in ballots to be counted provided they are postmarked by Election Day and received within five business days thereafter. The 5–4 ruling, authored by Justice Amy Coney Barrett and joined by Chief Justice John Roberts alongside the court’s three liberal justices, was a notable defeat for the Republican National Committee, which had brought the challenge. With the 2026 midterm elections now fewer than four months away, the decision preserves a counting window that election administrators and voting rights advocates have argued is essential to ensuring that legitimately cast ballots are not discarded on technical grounds.
The outcome is a meaningful, if limited, protection for ballot access. Mail-in voting has become a flashpoint in Republican-led litigation strategies since 2020, with the party consistently seeking to narrow the window in which absentee ballots can be received and counted. The court’s refusal to further restrict that window — even with a conservative-majority bench — reflects the difficulty of constructing a legal argument that discarding timely-postmarked ballots serves any legitimate state interest in election integrity.
Geofence Warrants: Privacy Wins a Round
On digital privacy, the court issued a 6–3 ruling restricting law enforcement’s use of geofence warrants — a technique that compels technology companies such as Google to search their vast location databases and identify every user present within a defined geographic area at a specific time. The case arose from a bank robbery in which the geofence drawn by investigators encompassed not only the bank itself but also a neighboring church and a senior citizens’ home, sweeping in the data of individuals with no connection to the crime. Justice Elena Kagan wrote for the majority, sending the case back to a lower court to assess whether the specific search met the Fourth Amendment’s reasonableness standard.
The ruling does not categorically prohibit geofence warrants, but it signals that the court views the technique as constitutionally fraught when the geographic scope captures large numbers of innocent people. Civil liberties advocates have long argued that geofence warrants invert the Fourth Amendment’s logic by requiring a general search of a population in hopes of identifying a suspect, rather than establishing probable cause against a specific individual before conducting a search. Kagan’s majority opinion stops short of resolving that deeper question, but its skepticism of overbroad geofences represents a meaningful, if incremental, check on surveillance technology.
Birthright Citizenship: The Term’s Remaining Flashpoint
The most constitutionally consequential case still awaiting resolution is Trump v. Barbara, in which the Trump administration has asked the court to uphold an executive order seeking to deny birthright citizenship to children born in the United States to parents who are present in the country without legal authorization. Opponents of the order argue, with substantial textual and historical support, that it directly violates the Fourteenth Amendment’s citizenship clause, which grants citizenship to all persons born on U.S. soil. The amendment was ratified in 1868 specifically to establish an unambiguous, universal rule of birthright citizenship, and no court has ever upheld a restriction of this kind.
The administration’s argument rests on a contested reinterpretation of the phrase “subject to the jurisdiction thereof,” claiming that undocumented immigrants’ children fall outside its scope. Legal scholars across the ideological spectrum have largely rejected this reading, but the court’s willingness to hear the case has itself generated alarm among immigration law experts. A ruling in the administration’s favor would represent one of the most dramatic reinterpretations of a constitutional amendment in the court’s modern history and would strip citizenship from a class of people born on American soil — a consequence with no precedent in the post-Reconstruction era.
A Term That Has Already Reshaped American Law
Even before Tuesday’s final opinions, the 2025–2026 term had already produced rulings of historic consequence. The court effectively gutted what remained of the 1965 Voting Rights Act, a decision that promptly prompted Republican-controlled legislatures in several Southern states to redraw congressional maps in ways that diminish or eliminate majority-Black districts — reversing decades of hard-won representation. In a separate and significant rebuke of the administration, the court struck down President Trump’s sweeping tariff program, ruling that Congress had not granted the executive branch the authority to impose it and that Trump had exceeded the limits of his power.
Taken together, the term’s output reflects a court that has been willing to dramatically expand presidential power in some domains while imposing limits in others — a pattern that resists easy summary but whose cumulative effect on democratic institutions, regulatory governance, and civil rights will be felt for years to come.
