901.Assault on Custodial Officer (Pen. Code, §§ 240, 241.1)
The defendant is charged [in Count ] with assault on a custodial
officer [in violation of Penal Code section 241.1].
To prove that the defendant is guilty of this crime, the People must
1. The defendant did an act that by its nature would directly and
probably result in the application of force to a person;
2. The defendant did that act willfully;
3. When the defendant acted, (he/she) was aware of facts that
would lead a reasonable person to realize that (his/her) act by its
nature would directly and probably result in the application of
force to someone;
4. When the defendant acted, (he/she) had the present ability to
apply force to a person;
5. When the defendant acted, the person assaulted was lawfully
performing (his/her) duties as a custodial officer;
6. When the defendant acted, (he/she) knew, or reasonably should
have known, both that the person assaulted was a custodial
officer and that (he/she) was performing (his/her) duties as a

7. The defendant did not act (in self-defense/ [or] in defense of
Someone commits an act willfully when he or she does it willingly or on
purpose. It is not required that he or she intend to break the law, hurt
someone else, or gain any advantage.
The terms application of force and apply force mean to touch in a
harmful or offensive manner. The slightest touching can be enough if it
is done in a rude or angry way. Making contact with another person,
including through his or her clothing, is enough. The touching does not
have to cause pain or injury of any kind.
[The touching can be done indirectly by causing an object [or someone
else] to touch the other person.]
[The People are not required to prove that the defendant actually
The People are not required to prove that the defendant actually
intended to use force against someone when (he/she) acted.
No one needs to actually have been injured by the defendant’s act. But
if someone was injured, you may consider that fact, along with all the
other evidence, in deciding whether the defendant committed an
assault[, and if so, what kind of assault it was].
[Voluntary intoxication is not a defense to assault.]
Acustodial officer is someone who works for a law enforcement agency
of a city or county, is responsible for maintaining custody of prisoners,
and helps operate a local detention facility. [A (county jail/city jail/
<insert other detention facility>) is a local detention
facility.] [A custodial officer is not a peace officer.]

The court has a sua sponte duty to give an instruction deﬁning the elements of the
If there is sufficient evidence of self-defense or defense of another, the court has a
sua sponte duty to instruct on the defense. Give bracketed element 7 and any
appropriate defense instructions. (See CALCRIM Nos. 3470–3477.)
In addition, the court has a sua sponte duty to instruct on defendant’s reliance on
self-defense as it relates to the use of excessive force. (People v. White (1980) 101
Cal.App.3d 161, 167–168 [161 Cal.Rptr. 541].) If excessive force is an issue, the
court has a sua sponte duty to instruct the jury that the defendant is not guilty of
the offense charged, or any lesser included offense in which lawful performance is
an element, if the defendant used reasonable force in response to excessive force.
(People v. Olguin (1981) 119 Cal.App.3d 39, 46–47 [173 Cal.Rptr. 663].) If lawful
performance is an issue, give the appropriate portions of CALCRIM No. 2671,
Lawful Performance: Custodial Offıcer.
In the bracketed deﬁnition of “local detention facility,” do not insert the name of a
speciﬁc detention facility. Instead, insert a description of the type of detention
facility at issue in the case. (See People v. Flood (1998) 18 Cal.4th 470, 482 [76
Cal.Rptr.2d 180, 957 P.2d 869] [jury must determine if alleged victim is a peace
officer]; see Penal Code section 6031.4 [deﬁning local detention facility].)
Do not give an attempt instruction in conjunction with this instruction. There is no
crime of “attempted assault” in California. (In re James M. (1973) 9 Cal.3d 517,
519 [108 Cal.Rptr. 89, 510 P.2d 33].)
