441 Negligent Use of Deadly Force by Peace Officer—Essential Factual Elements


A peace officer may use deadly force only when necessary in defense of human life. [Name of plaintiff] claims that [name of defendant] was negligent in using deadly force to [arrest/detain/ [,/or] prevent escape of/ [,/or] overcome resistance to] [him/her/nonbinary pronoun/name of decedent]. To establish this claim, [name of plaintiff] must prove all of the following:

1.That [name of defendant] was a peace officer;

2.That [name of defendant] used deadly force on [name of plaintiff/decedent];

3.That [name of defendant]’s use of deadly force was not necessary to defend human life;

4.That [name of plaintiff/decedent] was [harmed/killed]; and

5.That [name of defendant]’s use of deadly force was a substantial factor in causing [name of plaintiff/decedent]’s [harm/death].

[Name of defendant]’s use of deadly force was necessary to defend human life only if a reasonable officer in the same situation would have believed, based on the totality of the circumstances known to or perceived by [name of defendant] at the time, that deadly force was necessary [either]:

[to defend against an imminent threat of death or serious bodily injury to [name of defendant] [and/or] [another person]][; or/.]]

[to apprehend a fleeing person for a felony, when all of the following conditions are present:

i.The felony threatened or resulted in death or serious bodily injury to another;

ii.[Name of defendant] reasonably believed that the person fleeing would cause death or serious bodily injury to another unless immediately apprehended; and

iii.[Name of defendant] made reasonable efforts to identify [himself/herself/nonbinary pronoun] as a peace officer and to warn that deadly force may be used, unless the officer had objectively reasonable grounds to believe the person is aware of those facts.]

[A peace officer must not use deadly force against persons based only on the danger those persons pose to themselves, if an objectively reasonable officer would believe the person does not pose an imminent threat of death or serious bodily injury to the peace officer or to another person.]

[A person being [arrested/detained] has a duty not to use force to resist a peace officer unless the peace officer is using unreasonable force.]

[“Deadly force” is force that creates a substantial risk of causing death or serious bodily injury. It is not limited to the discharge of a firearm.]

A threat of death or serious bodily injury is “imminent” if, based on the totality of the circumstances, a reasonable officer in the same situation would believe that a person has the present ability, opportunity, and apparent intent to immediately cause death or serious bodily injury to the peace officer or to another person. An imminent harm is not merely a fear of future harm, no matter how great the fear and no matter how great the likelihood of the harm, but is one that, from appearances, must be instantly confronted and addressed.

“Totality of the circumstances” means all facts known to or perceived by the peace officer at the time, including the conduct of [name of defendant] and [name of plaintiff/decedent] leading up to the use of deadly force. In determining whether [name of defendant]’s use of deadly force was necessary in defense of human life, you must consider [name of defendant]’s tactical conduct and decisions before using deadly force on [name of plaintiff/decedent] and whether [name of defendant] used other available resources and techniques as [an] alternative[s] to deadly force, if it was reasonably safe and feasible to an objectively reasonable officer.

[A peace officer who makes or attempts to make an arrest does not have to retreat or stop because the person being arrested is resisting or threatening to resist. Tactical repositioning or other deescalation tactics are not retreat. A peace officer does not lose the right to self-defense by using objectively reasonable force to [arrest/detain/ [,/or] prevent escape/ [,/or] overcome resistance].]


Directions for Use

Use this instruction for a negligence claim arising from a peace officer’s use of deadly force. Penal Code section 835a preserves the “reasonable force” standard for nondeadly force, but creates a separate, higher standard that authorizes a peace officer to use deadly force only when “necessary in defense of human life.” If the plaintiff claims that the defendant used both deadly and nondeadly force, or if the jury must decide whether the force used was deadly or nondeadly, this instruction may be used along with the corresponding essential elements for negligence involving nondeadly force. See CACI No. 440, Negligent Use of Nondeadly Force by Law Enforcement Officer in Arrest or Other Seizure—Essential Factual Elements.

Element 1 may be stipulated to or decided by the judge as a matter of law. In such a case, the judge must instruct the jury that the defendant was a peace officer. If there are contested issues of fact regarding element 1, include the specific factual findings necessary for the jury to determine whether the defendant was a peace officer.

Select either or both bracketed options concerning the justifications for using deadly force under Penal Code section § 835a(c) depending on the facts of the case. If only one justification is supported by the facts, omit the either/or language. Include the bracketed sentence following the justifications if the plaintiff claims that the only threat the plaintiff posed was self-harm. A peace officer may not use deadly force against a person based on a danger that person poses to themselves if an objectively reasonable officer would believe the person does not pose an imminent threat of death or serious bodily injury to the peace officer or to another person. (Pen. Code, § 835a(c)(2).)

“Deadly force” means any use of force that creates a substantial risk of causing death or serious bodily injury, including, but not limited to, the discharge of a firearm. (Pen. Code, § 835a(e)(1).) The definition may be omitted from the instruction if a firearm was used. Note that this definition does not require that the encounter result in the death of the person against whom the force was used. If there is no dispute about the use of deadly force, the court should instruct the jury that deadly force was used.

Include the final bracketed paragraph only if the defendant claims that the person being arrested resisted arrest or threatened resistance.

In a wrongful death or survival action, use the name of the decedent victim where applicable and further modify the instruction as appropriate.

“There is an abundance of authority permitting a plaintiff to go to the jury on both intentional and negligent tort theories, even though they are inconsistent. It has often been pointed out that there is no prohibition against pleading inconsistent causes of action stated in as many ways as plaintiff believes his evidence will show, and he is entitled to recover if one well pleaded count is supported by the evidence.” (Grudt v. City of Los Angeles (1970) 2 Cal.3d 575, 586 [86 Cal.Rptr. 465, 468 P.2d 825].)

“The evidence relevant to negligence and intentional tort overlaps here and presents a case similar to Grudt v. City of Los Angeles, supra, 2 Cal.3d 575. … [¶] This court held it was reversible error to exclude the negligence issue from the jury even though plaintiff also had pled intentional tort. The court pointed to the rule that a party may proceed on inconsistent causes of action unless a nonsuit is appropriate.” (Munoz v. Olin (1979) 24 Cal.3d 629, 635 [156 Cal.Rptr. 727, 596 P.2d 1143].)

“[T]here is no right to use force, reasonable or otherwise, to resist an unlawful detention … .” (Evans v. City of Bakersfield (1994) 22 Cal.App.4th 321, 333 [27 Cal.Rptr.2d 406].)

“[E]xecution of an unlawful arrest or detention does not give license to an individual to strike or assault the officer unless excessive force is used or threatened; excessive force in that event triggers the individual’s right of self-defense.” (Evans, supra, 22 Cal.App.4th at p. 331, original italics, internal citation omitted.)
