D. SELF-DEFENSE AND DEFENSE OF ANOTHER

3470 . Right to Self-Defense or Defense of Another (Non-Homicide)

Self-defense is a defense to <insert list of pertinent crimes

char ged> . The defendant is not guilty of (that/those crime[s]) if (he/she)

used force against the other person in lawful (self-defense/ [or] defense of

another). The defendant acted in lawful (self-defense/ [or] defense of

another) if:

1. The defendant reasonably believed that (he/she/ [or] someone else/

[or] ) was in imminent

danger of suf fering bodily injury [or was in imminent danger of

being touched unlawfully];

2. The defendant reasonably believed that the immediate use of

force was necessary to defend against that danger;

3. The defendant used no more force than was reasonably necessary

to defend against that danger.

Belief in future harm is not su f ficient, no matter how gr eat or how likely

the harm is believed to be. The defendant must have believed ther e was

(imminent danger of bodily injury to (himself/herself/ [or] someone else)/

[or] an imminent danger that (he/she/ [or] someone else) would be

touched unlawfully). Defendant’ s belief must have been r easonable and

(he/she) must have acted because of that belief. The defendant is only

entitled to use that amount of force that a r easonable person would

believe is necessary in the same situation. If the defendant used more

force than was r easonable, the defendant did not act in lawful

(self-defense/ [or] defense of another).

When deciding whether the defendant’ s beliefs were r easonable, consider

all the circumstances as they wer e known to and appear ed to the

defendant and consider what a r easonable person in a similar situation

with similar knowledge would have believed. If the defendant’ s beliefs

were r easonable, the danger does not need to have actually existed.

[The slightest touching can be unlawful if it is done in a rude or angry

way . Making contact with another person, including thr ough his or her

clothing, is enough. The touching does not have to cause pain or injury

of any kind.]

[The defendant’ s belief that (he/she/ [or] someone else) was thr eatened

may be reasonable even if (he/she) r elied on information that was not

true. However , the defendant must actually and reasonably have believed

that the information was true.]

Bg94c

[If you find that threatened or

harmed the defendant [or others] in the past, you may consider that

information in deciding whether the defendant’ s conduct and beliefs

were r easonable.]

[If you find that the defendant knew that

victim> had threatened or harmed others in the past, you may consider

that information in deciding whether the defendant’ s conduct and beliefs

were r easonable.]

[Someone who has been threatened or harmed by a person in the past is

justified in acting more quickly or taking greater self-defense measur es

against that person.]

[If you find that the defendant received a thr eat fr om someone else that

(he/she) reasonably associated with ,

you may consider that thr eat in deciding whether the defendant was

justified in acting in (self-defense/ [or] defense of another).]

[A defendant is not requir ed to r etreat. He or she is entitled to stand his

or her ground and defend himself or herself and, if reasonably necessary ,

to pursue an assailant until the danger of (death/bodily injury/

) has passed. This is so even if safety could

have been achieved by retr eating.]

The People have the burden of proving beyond a r easonable doubt that

the defendant did not act in lawful (self-defense/ [or] defense of another).

If the People have not met this burden, you must find the defendant not

BENCH NOTES

Instructional Duty

The court must instruct on a defense when the defendant requests it and there is

substantial evidence supporting the defense. The court has a sua sponte duty to

instruct on a defense if there is substantial evidence supporting it and either the

defendant is relying on it or it is not inconsistent with the defendant’ s theory of the

case. When the court concludes that the defense is supported by substantial evidence

and is inconsistent with the defendant’ s theory of the case, however , it should

ascertain whether defendant wishes instruction on this alternate theory . ( People v .

Gonzales (1999) 74 Cal.App.4th 382, 389-390 [88 Cal.Rptr .2d 11 1]; People v .

Br everman (1998) 19 Cal.4th 142, 157 [77 Cal.Rptr .2d 870, 960 P .2d 1094].)

Substantial evidence means evidence of a defense, which, if believed, would be

suf ficient for a reasonable jury to find a reasonable doubt as to the defendant’ s guilt.

( People v . Salas (2006) 37 Cal.4th 967, 982-983 [38 Cal.Rptr .3d 624, 127 P .3d 40].)

CALCRIM No. 3470 DEFENSES AND INSANITY

Bg94d

On defense request and when supported by suf ficient evidence, the court must

instruct that the jury may consider the ef fect of “antecedent threats and assaults

against the defendant on the reasonableness of defendant’ s conduct.” ( People v .

Garvin (2003) 1 10 Cal.App.4th 484, 488 [1 Cal.Rptr .3d 774].) The court must also

instruct that the jury may consider previous threats or assaults by the aggressor

against someone else or threats received by the defendant from a third party that the

defendant reasonably associated with the aggressor . (See People v . Pena (1984) 151

Cal.App.3d 462, 475 [198 Cal.Rptr . 819]; People v . Minifie (1996) 13 Cal.4th 1055,

1065, 1068 [56 Cal.Rptr .2d 133, 920 P .2d 1337]; see also CALCRIM No. 505,

RELA TED ISSUES

Brandishing W eapon in Defense of Another

The defense of others is a defense to a charge of brandishing a weapon under Penal

Code section 417(a)(2). ( People v . Kirk (1986) 192 Cal.App.3d Supp. 15, 19 [238

Cal.Rptr . 42].)

Reasonable Person Standard Not Modified by Evidence of Mental Impairment

In People v . Jefferson (2004) 119 Cal.App.4th 508, 519 [14 Cal.Rptr .3d 473], the

court rejected the argument that the reasonable person standard for self-defense

should be the standard of a mentally ill person like the defendant. “The common

law does not take account of a person’ s mental capacity when determining whether

he has acted as the reasonable person would have acted. The law holds ‘the

mentally deranged or insane defendant accountable for his negligence as if the

person were a normal, prudent person.’ (Prosser & Keeton, T orts (5th ed. 1984)

§ 32, p. 177.)” ( Ibid. ; see also Rest.2d T orts, § 283B.)

Reasonable Person Standard and Physical Limitations

A defendant’ s physical limitations are relevant when deciding the reasonable person

standard for self-defense. ( People v . Horn (2021) 63 Cal.App.5th 672, 686 [277

Cal.Rptr .3d 901].) See also CALCRIM No. 3429, Reasonable Person Standard for

Physically Disabled Person .
