403.Natural and Probable Consequences
(Only Non-Target Offense Charged)
[Before you may decide whether the defendant is guilty of
<insert non-target offense>, you must decide whether (he/she) is guilty of
<insert target offense>.]
To prove that the defendant is guilty of <insert non-target
offense>, the People must prove that:
1. The defendant is guilty of <insert target offense>;
2. During the commission of <insert target offense> a
coparticipant in that <insert target offense>
committed the crime of <insert non-target offense>;
3. Under all of the circumstances, a reasonable person in the
defendant’s position would have known that the commission of
the <insert non-target offense> was a natural and
probable consequence of the commission of the
<insert target offense>.
Acoparticipant in a crime is the perpetrator or anyone who aided and
abetted the perpetrator. It does not include a victim or innocent
Anatural and probable consequence is one that a reasonable person
would know is likely to happen if nothing unusual intervenes. In
deciding whether a consequence is natural and probable, consider all of
the circumstances established by the evidence.
[Do not consider evidence of defendant’s intoxication in deciding
whether <insert non-target offense> was a natural and
probable consequence of <insert target offense>.]
To decide whether crime of <insert non-target offense> was
committed, please refer to the separate instructions that I (will give/have
given) you on (that/those) crime[s].
[The People are alleging that the defendant originally intended to aid
and abet <insert target offenses>.
If you decide that the defendant aided and abetted one of these crimes
and that <insert non-target offense> was a natural and
probable consequence of that crime, the defendant is guilty of
<insert non-target offense>. You do not need to agree about
which of these crimes the defendant aided and abetted.]

The court has a sua sponte duty to instruct on aiding and abetting when the
prosecution relies on it as a theory of culpability. (People v. Beeman (1984) 35
Cal.3d 547, 560–561 [199 Cal.Rptr. 60, 674 P.2d 1318].)
The court has a sua sponte duty to identify and instruct on any target offense
relied on by the prosecution as a predicate offense when substantial evidence
supports the theory. Give all relevant instructions on the alleged target offense or
offenses. The court, however, does not have to instruct on all potential target
offenses supported by the evidence if the prosecution does not rely on those
offenses. (People v. Prettyman (1996) 14 Cal.4th 248, 267–268 [58 Cal.Rptr.2d
827, 926 P.2d 1013]; see People v. Huynh (2002) 99 Cal.App.4th 662, 677–678
[121 Cal.Rptr.2d 340] [no sua sponte duty to instruct on simple assault when
prosecutor never asked court to consider it as target offense].)
The target offense is the crime that the accused parties intended to commit. The
non-target is an additional unintended crime that occurs during the commission of
Do not give the ﬁrst bracketed paragraph in cases in which the prosecution is also
pursuing a conspiracy theory.
Give the bracketed paragraph beginning, “Do not consider evidence of defendant’s
intoxication” when instructing on aiding and abetting liability for a non-target
offense. (People v. Mendoza (1998) 18 Cal.4th 1114, 1134 [77 Cal.Rptr.2d 428, 959
Give CALCRIM No. 400, Aiding and Abetting: General Principles, and
CALCRIM No. 401, Aiding and Abetting: Intended Crimes, before this instruction.
This instruction should be used when the prosecution relies on the natural and
probable consequences doctrine and charges only non-target crimes. If both target
and non-target crimes are charged, give CALCRIM No. 402, Natural and Probable
Consequences Doctrine (Target and Non-Target Offenses Charged).

Challenges to Crimes, § 140.10 (Matthew Bender).
In People v. Prettyman (1996) 14 Cal.4th 248, 268 [58 Cal.Rptr.2d 827, 926 P.2d
1013], the court concluded that the trial court must sua sponte identify and describe
for the jury any target offenses allegedly aided and abetted by the defendant.
Although no published case to date gives a clear deﬁnition of the terms “natural”
and “probable,” nor holds that there is a sua sponte duty to deﬁne them, we have
included a suggested deﬁnition. (See People v. Prettyman, supra, 14 Cal.4th at p.
291 (conc. & dis. opn. of Brown, J.); see also People v. Coffman and Marlow
(2004) 34 Cal.4th 1, 107–109 [17 Cal.Rptr.3d 710, 96 P.3d 30] [court did not err in
failing to deﬁne “natural and probable.”])
