Known Self-Defense Facts Must Be Disclosed in Probable-Cause Affidavits, But Qualified Immunity Applies Absent Clearly Established Law

Introduction

In Corey Kendig v. Nicholas Stolar, the Third Circuit addressed an important Fourth Amendment question: must a police officer include known facts supporting self-defense in an affidavit of probable cause when seeking charges or an arrest warrant?

Corey Kendig was charged with criminal homicide, aggravated assault, and recklessly endangering another person after he shot Jeremy Jones during a late-night fight outside Partner’s Tavern. Kendig was later acquitted by a jury. He then sued Pennsylvania State Trooper Nicholas Stolar under 42 U.S.C. § 1983, alleging false arrest, false imprisonment, and malicious prosecution in violation of the Fourth Amendment.

The District Court granted summary judgment to Trooper Stolar on qualified-immunity grounds. The Third Circuit affirmed, but it clarified the law going forward: where an officer conclusively knows facts establishing self-defense that negate the mens rea of the charged offense or excuse the conduct, those facts must be disclosed to the magistrate.

Summary of the Opinion

The Third Circuit held that facts supporting self-defense can be relevant to probable cause when, under state law, self-defense negates an element of the charged offense or excuses the conduct. Because Pennsylvania law treats self-defense as negating the required mental state for the crimes charged against Kendig, the court concluded that Trooper Stolar should have included known self-defense facts in the affidavit of probable cause.

However, the court also held that the law was not clearly established at the time of Stolar’s conduct. Therefore, although the opinion announces an important rule for future cases, Stolar was entitled to qualified immunity. The District Court’s judgment was affirmed.

Analysis

New Legal Principle Established

The Third Circuit adopted the following rule:

An officer need not investigate or evaluate every possible affirmative defense before making an arrest or filing charges. But when the officer conclusively knows facts establishing self-defense, and those facts negate the required mental state of the charged offense or excuse the conduct, the officer must disclose those facts to the magistrate in the probable-cause affidavit.

The court emphasized that the magistrate—not the officer—must decide whether probable cause exists. An officer may not present only inculpatory facts while withholding known exculpatory facts supporting self-defense.

Precedents Cited

Qualified Immunity and Summary Judgment

The court relied on Orsatti v. N. J. State Police and Harlow v. Fitzgerald for the basic qualified-immunity rule: officials are shielded from damages liability unless they violate clearly established statutory or constitutional rights of which a reasonable person would have known.

Ashcroft v. al-Kidd, Reichle v. Howards, Sauers v. Borough of Nesquehoning, and Dist. of Columbia v. Wesby guided the “clearly established law” analysis. The Third Circuit explained that a plaintiff must identify controlling precedent or a robust consensus of persuasive authority placing the constitutional question beyond debate. Because no such authority existed in the Third Circuit at the time, qualified immunity applied.

Harvard v. Cesnalis, Merkle v. Upper Dublin Sch. Dist., and Anderson v. Liberty Lobby, Inc. were relevant to jurisdiction, summary judgment, and the standards for determining whether factual disputes preclude judgment as a matter of law.

Probable Cause and Fourth Amendment Seizures

The court cited Dowling v. City of Philadelphia, Lozano v. New Jersey, and Chiaverini v. City of Napoleon to explain that false arrest, false imprisonment, and malicious prosecution claims share a common requirement: the absence of probable cause.

Manuel v. City of Joliet, Bailey v. United States, and Cnty. of Riverside v. McLaughlin supplied the core Fourth Amendment principles governing arrest and detention. A seizure is reasonable only if supported by probable cause, and a warrantless arrestee must promptly be brought before a neutral magistrate.

Johnson v. United States was especially important to the court’s institutional reasoning. It underscored that probable-cause determinations should be made by neutral magistrates, not by officers engaged in investigating crime.

Affidavits of Probable Cause and Omissions

The court relied heavily on Wilson v. Russo, Dempsey v. Bucknell Univ., Franks v. Delaware, Illinois v. Gates, and Reedy v. Evanson. These cases establish that officers may not mislead magistrates through false statements or material omissions.

Andrews v. Scuilli reinforced that officers may not disregard plainly exculpatory evidence, even where substantial inculpatory evidence exists. This principle drove the court’s conclusion that known self-defense facts may need to be disclosed when they are exculpatory under the charged offense.

Affirmative Defenses and Self-Defense

The central doctrinal development came from Mazuka v. Rice Township Police Department. Although non-precedential, Judge Smith’s concurrence proposed the rule the Third Circuit now adopted: an affirmative defense is relevant to probable cause when a reasonable officer would conclusively know that it negates the required mental state or excuses the conduct.

The court also cited Holman v. City of York to note that affirmative defenses are not categorically irrelevant to probable cause.

Pennsylvania Self-Defense Law

Pennsylvania precedent was crucial because the charges against Kendig arose under Pennsylvania criminal law. The court cited In Int. of Smith, Commonwealth v. Fowlin, Commonwealth v. Flemings, Commonwealth v. Hooks, Commonwealth v. Hilbert, and Commonwealth v. Madison for the proposition that self-defense can negate the mens rea or unlawfulness elements of homicide, aggravated assault, and reckless endangerment.

Commonwealth v. Light showed that even partial self-defense evidence may affect the degree of homicide, distinguishing murder from manslaughter.

Other Circuit Authority

The court considered persuasive authority from other circuits, including Jocks v. Tavernier, Est. of Dietrich v. Burrows, Hodgkins ex rel. Hodgkins v. Peterson, Davis v. City of Apopka, United States v. Baker, Loftin v. City of Prentiss, Painter v. Robertson, and Fridley v. Horrighs.

These cases generally support the idea that officers may not ignore conclusively established facts showing an affirmative defense, but they also make clear that officers are not required to investigate every asserted defense or resolve disputed factual questions before making an arrest.

District Court Authorities

The court noted that district courts within the Third Circuit had generally not required officers to include affirmative-defense facts in probable-cause affidavits. It cited Rittacco v. Zelechowski, Gorman v. Bail, Berrios v. City of Philadelphia, and Lue v. Borough of Collingdale. This supported the conclusion that the relevant law was not clearly established when Stolar acted.

Legal Reasoning

The Third Circuit’s reasoning proceeded in two steps.

  1. Was there a constitutional problem? The court answered yes. Because Pennsylvania law treats self-defense as negating culpability for the charged offenses, known self-defense facts were potentially exculpatory. A magistrate could not properly assess probable cause if those facts were withheld.
  2. Was the right clearly established? The court answered no. Although the court established the rule prospectively, existing precedent did not clearly tell officers in the Third Circuit that omitting such affirmative-defense facts from an affidavit violated the Fourth Amendment.

This distinction allowed the court to recognize a constitutional principle while still affirming qualified immunity for Trooper Stolar.

Impact

This opinion is significant for future Fourth Amendment litigation in the Third Circuit. Going forward, police officers preparing probable-cause affidavits must disclose known facts supporting self-defense when those facts clearly negate an element of the charged offense or excuse the conduct.

The decision does not require officers to conduct a mini-trial at the scene, investigate every claimed defense, or predict whether a jury will accept self-defense. But it does prohibit officers from withholding known, material, exculpatory facts from the magistrate.

For civil-rights plaintiffs, the case creates a clearer path for challenging probable-cause affidavits that omit known self-defense facts. For law enforcement, it reinforces the need for full and balanced factual presentations to judicial officers.

Complex Concepts Simplified

  • Probable cause: A reasonable basis to believe a person committed a crime. It is less than proof beyond a reasonable doubt but more than mere suspicion.
  • Affidavit of probable cause: A written statement by an officer presenting facts to a magistrate to justify an arrest warrant or charges.
  • Affirmative defense: A defense that may excuse or justify conduct even if the basic act occurred. Self-defense is a common example.
  • Mens rea: The mental state required for a crime, such as intent, knowledge, recklessness, or negligence.
  • Qualified immunity: A doctrine shielding government officials from civil damages unless they violated a clearly established legal right.

Conclusion

Corey Kendig v. Nicholas Stolar establishes an important Fourth Amendment rule in the Third Circuit: known facts supporting self-defense cannot be withheld from a magistrate when those facts conclusively bear on culpability for the charged offense.

Nevertheless, because this rule was not clearly established when Trooper Stolar acted, he was protected by qualified immunity. The result is both prospective and practical: officers are not required to resolve every defense, but they must not conceal known exculpatory self-defense facts from the neutral judicial officer responsible for deciding probable cause.
