Imbler v. Pachtman
The Supreme Court ruled that a state prosecutor cannot be sued for money damages for actions taken while deciding to prosecute a case and presenting it in court, even where the defendant claims those actions violated his constitutional rights.
The decision gives prosecutors the same absolute immunity long enjoyed by judges for their courtroom-related work, a shield the Court said was necessary to let prosecutors do their jobs without fear of being sued by every defendant they convict.
“We conclude that the considerations outlined above dictate the same absolute immunity under § 1983 that the prosecutor enjoys at common law.”
The Court's central holding granting prosecutors absolute immunity from civil rights damages suits.
How it got here: A federal trial court dismissed Imbler's civil rights suit against the prosecutor on immunity grounds, the Ninth Circuit affirmed, and Imbler asked the Supreme Court to review that ruling.
The Case in Depth
What happened
Paul Imbler was convicted of murder in 1961 based largely on eyewitness identifications and sentenced to death. Years later, evidence emerged that the prosecutor's key witness had lied and that favorable evidence had been withheld, and a federal court eventually freed Imbler through habeas corpus. Imbler then sued the prosecutor, Richard Pachtman, seeking millions of dollars in damages for allegedly conspiring to convict him unlawfully.
The question before the Court
Can a state prosecutor be sued for money damages under the federal civil rights law for decisions made while charging and trying a criminal case, even if those decisions violated the defendant's rights?
The Court's answer
No — the Court ruled that a prosecutor cannot be sued for money damages under the federal civil rights law for decisions made while initiating a case and presenting it in court, even if those decisions violated the defendant's rights. Borrowing the same absolute immunity that long protected prosecutors from malicious-prosecution lawsuits at common law, the Court held that Congress did not mean to strip that protection away when it passed the civil rights statute.
The Court reasoned that exposing prosecutors to personal liability for their courtroom decisions would make them overly cautious, invite constant relitigation of old criminal trials in new civil lawsuits, and could distort how judges handle post-conviction appeals. The ruling covers only a prosecutor's core advocacy work, not necessarily investigative or administrative conduct.

Why it matters
People who believe a prosecutor's misconduct — such as knowingly using false testimony — contributed to a wrongful conviction cannot collect damages from that prosecutor in a civil rights lawsuit, even after being exonerated. Wrongfully convicted people must instead rely on criminal prosecution of the prosecutor or professional discipline, both rarely used, to address such misconduct.
What changes now
This is a final merits decision resolving the scope of prosecutorial immunity under the federal civil rights law nationwide. Imbler's lawsuit against the prosecutor is over, since the immunity defeats the claims at the outset. The ruling leaves open, for future cases, whether prosecutors acting as investigators or administrators — rather than advocates in court — receive the same absolute protection or only a lesser, qualified immunity.
What this does not decide
The Court expressly limited its holding to a prosecutor's role in initiating a prosecution and presenting the state's case in court. It did not decide whether the same absolute immunity applies when a prosecutor acts more like an investigator or administrator, leaving that question for future cases.
Concurrences and dissents
Concurrence — Justice White
Justice White agreed that a prosecutor is absolutely immune from suits claiming he knowingly used false testimony in court, since that mirrors the immunity prosecutors long had for malicious prosecution and defamation. But he would not extend absolute immunity to claims that a prosecutor unconstitutionally withheld favorable evidence from the defense, arguing that no such common-law immunity ever existed and that allowing suits for suppression would encourage more disclosure rather than harm the judicial process.
How the Court got there
The legal reasoning, step by step
- The Court explained that it has long read the federal civil rights law to preserve traditional immunities recognized at common law rather than wipe them out silently, pointing to its earlier rulings preserving immunity for legislators and judges and qualified immunity for other executive officials.
- Applying that same method to prosecutors, the Court found that at common law a prosecutor deciding whether to charge someone and how to present a case in court had long been treated much like a judge or grand juror, and enjoyed absolute immunity from lawsuits such as malicious prosecution.
- The Court weighed the policy reasons behind that common-law rule — preventing a flood of retaliatory lawsuits from people a prosecutor failed to convict, avoiding constant relitigation of old criminal trials in new civil courtrooms, and keeping prosecutors from softening their judgment out of fear of personal liability — and found these reasons apply with full force to constitutional claims as well.
- The Court concluded that giving prosecutors only a lesser, qualified immunity would make them overly cautious, could tempt judges deciding post-conviction appeals to go easy on the facts to protect the prosecutor from a future lawsuit, and would ultimately harm the fairness of the criminal justice system.
- The Court limited its ruling to conduct 'intimately associated with the judicial phase of the criminal process' — initiating a case and presenting it in court — leaving open whether the same absolute protection extends to a prosecutor's investigative or administrative work.
