Kumar v. Koester
Headline: Prosecutor Shielded by Absolute Immunity in Civil Rights Case
Citation: 131 F. 4th 746
Case Summary
Kumar v. Koester, decided by Ninth Circuit on March 12, 2025, resulted in a defendant win outcome. The Ninth Circuit affirmed the district court's grant of summary judgment to the defendant, a former federal prosecutor, in a civil rights lawsuit brought by the plaintiff. The plaintiff alleged that the defendant violated his Fourth Amendment rights by obtaining a search warrant based on false or reckless statements. The court held that the prosecutor was entitled to absolute prosecutorial immunity because the actions taken to obtain the warrant were in furtherance of his prosecutorial duties. The court held: The Ninth Circuit affirmed the grant of summary judgment to the defendant, a former federal prosecutor, holding that he was entitled to absolute prosecutorial immunity.. The court reasoned that the prosecutor's actions in seeking the search warrant, including the alleged misrepresentations or omissions in the affidavit, were part of the judicial phase of the prosecution and thus protected by absolute immunity.. The plaintiff's claim that the prosecutor violated his Fourth Amendment rights by obtaining a search warrant based on false or reckless statements was dismissed because prosecutorial immunity bars such claims.. The court distinguished the prosecutor's actions in seeking the warrant from investigative functions, which might not be covered by absolute immunity.. The plaintiff failed to demonstrate that the prosecutor acted outside the scope of his official duties when seeking the warrant.. This decision reinforces the broad scope of absolute prosecutorial immunity in the Ninth Circuit, particularly concerning actions taken to obtain search warrants. It signals that prosecutors are largely shielded from civil liability for alleged misconduct during the warrant application process, even if the warrant is later found to be invalid, unless their actions fall clearly outside their prosecutorial role.

Q: What is the difference between prosecutorial and investigative functions for immunity purposes?
Prosecutorial functions involve actions taken in initiating or pursuing a criminal prosecution, such as presenting evidence to a grand jury or seeking a warrant. Investigative functions are typically those performed before a prosecution is formally initiated or when acting in a capacity other than as a prosecutor. Absolute immunity generally protects prosecutorial functions.
Q: Can a prosecutor ever be sued for actions taken while seeking a search warrant?
Generally, no, if the actions are considered part of the prosecutorial function. Seeking a search warrant, even if based on allegedly false information, is typically viewed as a prosecutorial act protected by absolute immunity. However, if the prosecutor were acting purely as an investigator or in a non-prosecutorial capacity, immunity might not apply.
Q: What does 'absolute immunity' mean in this context?
Absolute immunity means that a prosecutor cannot be sued for damages for actions taken within their official prosecutorial capacity, regardless of their motive or intent. This doctrine is designed to protect prosecutors from harassment and undue interference in their duties, ensuring vigorous prosecution.
