Mitchell v. Forsyth
The Supreme Court ruled that a former Attorney General is not automatically shielded from lawsuits over his national-security wiretap decisions, but held that officials denied the lesser protection of qualified immunity can appeal that ruling immediately, before any trial takes place.
Applying that new appeal rule to the facts, the Court found that in 1970 it was not yet clearly established that warrantless domestic-security wiretaps were unconstitutional, so the Attorney General was entitled to qualified immunity after all.
“The entitlement is an immunity from suit rather than a mere defense to liability; and like an absolute immunity, it is effectively lost if a case is erroneously permitted to go to trial.”
Explaining why qualified-immunity denials must be immediately appealable.
How it got here: A federal trial court denied Mitchell absolute and qualified immunity and granted Forsyth summary judgment on liability; the Third Circuit affirmed on absolute immunity but said qualified immunity could not yet be appealed.
The Case in Depth
What happened
In 1970, the FBI told Attorney General John Mitchell that an antiwar group had discussed bombing federal buildings and kidnapping a national security adviser. Mitchell authorized a warrantless wiretap on a group member's phone, which also picked up conversations with Keith Forsyth, who was never implicated in any plot. After learning of the wiretap during an unrelated criminal case, Forsyth sued Mitchell for violating his rights.
The question before the Court
Could a former Attorney General claim complete immunity from a lawsuit over a warrantless national-security wiretap he authorized, and could he immediately appeal a ruling that he wasn't protected?
The Court's answer
Partly — the Court rejected the claim that the Attorney General has complete immunity from lawsuits over national-security actions, but it ruled that officials denied qualified immunity can appeal that ruling immediately, and it ultimately held the Attorney General was protected by qualified immunity here.
The Court found the Attorney General's national-security work lacked the historical and practical justifications supporting absolute immunity for judges, prosecutors, or the President. But because a wrongly denied qualified-immunity claim can never be fully restored once a trial happens, the Court held such denials can be appealed right away. On the merits, it concluded that in 1970 it was not yet clearly established that warrantless domestic-security wiretaps were unconstitutional, so the Attorney General was immune from this suit.

Why it matters
The decision reshaped how lawsuits against government officials proceed: officials denied qualified immunity can now get immediate appellate review instead of waiting through a full trial. This became a foundational procedural rule governing countless civil-rights and constitutional lawsuits against police, prosecutors, and other officials for decades afterward.
What changes now
This is a final merits decision on the immunity questions. Because the Court held Mitchell was protected by qualified immunity, the case returns to the lower courts for entry of judgment in his favor rather than further proceedings on damages. The ruling's broader legacy is procedural: it established that denials of qualified immunity can be appealed immediately, a rule that has governed lawsuits against government officials ever since.
What this does not decide
The Court did not decide whether the wiretap actually violated the Constitution — it assumed it did for purposes of the immunity analysis — and it did not grant national-security officials absolute immunity generally. It also left open whether other kinds of pretrial rulings besides qualified immunity might qualify for the same immediate-appeal treatment.
Concurrences and dissents
Concurrence in part — Justice Burger
Chief Justice Burger joined the appealability and merits portions of the opinion but argued the Court reached the wrong conclusion on absolute immunity. Drawing on the logic that congressional aides share their bosses' immunity, he argued a Cabinet officer acting as the President's aide in national security matters should receive the same absolute immunity as the President himself.
Concurrence in part — Justice O'Connor
Justice O'Connor joined the appealability ruling and the conclusion that the Attorney General was entitled to qualified immunity, agreeing that denials of qualified immunity, like absolute immunity or double-jeopardy rulings, must be immediately appealable. She declined to reach the absolute immunity question, since resolving qualified immunity was enough to decide the case.
Concurrence — Justice Stevens
Justice Stevens agreed with the ultimate outcome but for a very different reason: he would have held the Attorney General absolutely immune, reasoning that Congress had comprehensively regulated wiretapping yet deliberately left no damages remedy against officials exercising the President's national-security wiretap authority, so courts should not create one.
Dissent in part — Justice Brennan
“I therefore dissent from its holding that denials of qualified immunity, at least where they rest on undisputed facts, are generally appealable.”Brennan's core objection to letting officials immediately appeal qualified-immunity denials.
Justice Brennan agreed there was no absolute immunity but dissented from allowing immediate appeals of qualified immunity denials, arguing the immunity question is too closely tied to the merits to count as 'separate' under the collateral order doctrine. He also argued the majority mischaracterized the record by assuming the trial court had resolved a disputed factual issue about the wiretap's purpose.
How the Court got there
The legal reasoning, step by step
- The Court asked whether the Attorney General's national-security duties deserved the same complete, or 'absolute,' immunity given to judges, prosecutors, and the President. It looked for a historical or common-law tradition supporting that kind of blanket protection for national-security work and found none, unlike the well-established traditions behind judicial and prosecutorial immunity.
- The Court also noted that national-security decisions, unlike courtroom battles, rarely produce open winners and losers who then sue in retaliation, so the risk of a flood of vindictive lawsuits was much lower than for judges or prosecutors, further undercutting the case for absolute immunity.
- Having rejected absolute immunity, the Court turned to whether a ruling denying the weaker protection — qualified immunity, which shields officials unless they violated 'clearly established' rights — could be appealed immediately under the collateral order doctrine, a narrow exception letting certain rulings be appealed before a case is fully over.
- The Court reasoned that qualified immunity is not just a defense against paying damages but a right not to be dragged through a trial at all, and that right would be permanently lost if a case wrongly went to trial. It therefore held that denials of qualified immunity are immediately appealable, just like denials of absolute immunity or double-jeopardy claims.
- Turning to the merits, the Court asked whether it was 'clearly established' in November 1970 — well before the Court's 1972 Keith decision — that warrantless wiretaps targeting domestic security threats violated the Fourth Amendment. Because six administrations' Justice Departments had treated such wiretaps as lawful and lower courts were split at the time, the Court concluded the law was not yet clearly established.
- Since the unlawfulness of the wiretap was not clearly established when Mitchell acted, the Court held that the later Keith ruling could not retroactively strip him of qualified immunity for a decision made before that law existed.
