On July 1, 2024, the Supreme Court decided Trump v. United States (No. 23-939), Trump's appeal of the lower courts' refusal to dismiss the federal indictment charging him with conspiring to overturn the 2020 election. By a 6-3 vote, in an opinion by Chief Justice John Roberts, the Court held that a former president has absolute immunity from criminal prosecution for acts within his “conclusive and preclusive” constitutional authority, at least presumptive immunity for his other official acts, and no immunity for unofficial acts. The opinion calls the case “the first criminal prosecution in our Nation's history of a former President for actions taken during his Presidency.” It vacated the D.C. Circuit's judgment and sent the case back to the district court.
The Court drew the lines this way. For acts within the president's exclusive constitutional power, such as decisions about which crimes the Justice Department investigates and prosecutes, the immunity is absolute. For other official acts it is at least presumptive: the government must show that applying a criminal prohibition to the act would pose no “dangers of intrusion on the authority and functions of the Executive Branch.” The Court said it did not need to decide at this stage whether that protection is presumptive or absolute, which is why the holding says “at least.” Courts may not inquire into a president's motives when sorting official from unofficial acts, and an act is not unofficial merely because it allegedly violates a generally applicable law.
Applied to the indictment, the ruling put Trump's discussions with the Acting Attorney General about investigating election fraud beyond prosecution, as absolutely immune. His pressure on Vice President Mike Pence over the January 6 certification was official conduct and presumptively immune, and the Court sent it back for the district court to decide whether the government could rebut the presumption. The Court did not decide whether Trump's dealings with state officials and private parties, the fake-electors plan, or his January 6 tweets and Ellipse speech were official or unofficial, and remanded them to the district court. It wrote that “most of a President's public communications are likely to fall comfortably within the outer perimeter of his official responsibilities,” but that a president may also speak in an unofficial capacity, “perhaps as a candidate for office or party leader.”
The Court also limited what a prosecution can use. It rejected the government's argument that a jury could consider evidence about immune official acts for limited purposes, such as proving Trump knew his election-fraud claims were false, holding that the proposal “threatens to eviscerate the immunity we have recognized.” Justice Amy Coney Barrett joined the rest of the opinion but not this part, writing that “The Constitution does not require blinding juries to the circumstances surrounding conduct for which Presidents can be held liable.” Justice Sonia Sotomayor called the evidence holding “nonsensical.”
Roberts's opinion was joined in full by Justices Clarence Thomas, Samuel Alito, Neil Gorsuch and Brett Kavanaugh, and by Barrett except for the evidence section. Thomas also concurred separately to question whether the special counsel's office was lawfully established, a theory Judge Aileen Cannon later relied on in the classified documents case (see Judge Cannon, a Trump Appointee, Throws Out His Classified Documents Case on the Opening Day of the Republican Convention). Sotomayor, joined by Justices Elena Kagan and Ketanji Brown Jackson, dissented, writing that the ruling “makes a mockery of the principle, foundational to our Constitution and system of Government, that no man is above the law.” Jackson filed a separate dissent. The majority answered that the dissents “strike a tone of chilling doom that is wholly disproportionate to what the Court actually does today.” Trump called the decision a “BIG WIN FOR OUR CONSTITUTION AND DEMOCRACY” on Truth Social, CNN reported.
What the ruling does not do matters as much as what it does. It does not say a president cannot be prosecuted for crimes committed in office: the opinion states that “The President enjoys no immunity for his unofficial acts, and not everything the President does is official,” and notes that both sides agreed a former president can be prosecuted for unofficial acts. Apart from the Justice Department allegations and the Pence conversations, it left the official-or-unofficial question for the rest of the indictment to the lower courts. It also did not address indicting a sitting president. That bar is Justice Department policy, set out in a 2000 Office of Legal Counsel opinion, which a footnote in the Court's opinion mentions as the department's long-held view that “the separation of powers precludes the criminal prosecution of a sitting President” without ruling on it. Sotomayor's examples of what a president could now do, such as ordering a rival's assassination, are the dissent's reading of the majority's reasoning, not a holding.
Its effect on the federal cases against Trump was concrete. The election indictment was returned on August 1, 2023, and the trial, set for March 4, 2024, was on hold while Trump appealed; AP reported the case “has been frozen since last December.” After the ruling, NBC News reported that it was “virtually guaranteeing that Trump's trial won't start before Election Day.” On August 27, special counsel Jack Smith filed a 36-page revised indictment that kept all four counts but dropped the allegations about Trump's use of the Justice Department, which the Court had placed beyond prosecution, and stressed conduct that prosecutors said fell outside his official responsibilities. At the first hearing in nearly a year, on September 5, Trump's lawyers argued the ruling required dismissal of the entire case, a position Judge Tanya Chutkan did not accept. CBS News reported that Chutkan was still applying the ruling when Smith moved on November 25, 2024 to dismiss the case after Trump won the election (see Trump's Election Win Ends Both Federal Prosecutions Against Him Before Any Trial).
Trump's lawyers also invoked the ruling in New York, arguing that it barred testimony and evidence from his time in the White House in the hush money case. On December 16, 2024, Judge Juan Merchan rejected that, finding the charges rested on “private acts” and that Trump's communications about the payments while in the White House did not touch on official acts (see Trump Convicted on 34 Felony Counts for Stormy Daniels Hush Money Cover-Up). In March 2026, Judge Amit Mehta found, in the civil January 6 suits, that Trump's Ellipse speech and the Raffensperger call were unofficial acts (see Judge Rules Trump Cannot Escape the Jan. 6 Civil Lawsuit Because His Ellipse Speech and Raffensperger Call Were Not Official Acts).
