603.Attempted Voluntary Manslaughter: Heat of Passion—Lesser
Included Offense (Pen. Code, §§ 21a, 192, 664)
An attempted killing that would otherwise be attempted murder is
reduced to attempted voluntary manslaughter if the defendant
attempted to kill someone because of a sudden quarrel or in the heat of
The defendant attempted to kill someone because of a sudden quarrel
or in the heat of passion if:
1. The defendant took at least one direct but ineffective step toward
killing a person;
2. The defendant intended to kill that person;
3. The defendant attempted the killing because (he/she) was
4. The provocation would have caused a person of average
disposition to act rashly and without due deliberation, that is,
from passion rather than from judgment;
5. The attempted killing was a rash act done under the inﬂuence of
intense emotion that obscured the defendant’s reasoning or
Heat of passion does not require anger, rage, or any speciﬁc emotion. It
can be any violent or intense emotion that causes a person to act
without due deliberation and reﬂection.
In order for a sudden quarrel or heat of passion to reduce an attempted
murder to attempted voluntary manslaughter, the defendant must have
acted under the direct and immediate inﬂuence of provocation as I have
deﬁned it. While no speciﬁc type of provocation is required, slight or
remote provocation is not sufficient. Sufficient provocation may occur
over a short or long period of time.
It is not enough that the defendant simply was provoked. The defendant
is not allowed to set up (his/her) own standard of conduct. You must
decide whether the defendant was provoked and whether the
provocation was sufficient. In deciding whether the provocation was
sufficient, consider whether a person of average disposition, in the same
situation and knowing the same facts, would have reacted from passion
rather than judgment.
[If enough time passed between the provocation and the attempted
killing for a person of average disposition to “cool off” and regain his or
her clear reasoning and judgment, then the attempted murder is not
reduced to attempted voluntary manslaughter on this basis.]
The People have the burden of proving beyond a reasonable doubt that
the defendant attempted to kill someone and was not acting as a result
of a sudden quarrel or in the heat of passion. If the People have not met
this burden, you must ﬁnd the defendant not guilty of attempted

The court has a sua sponte duty to instruct on attempted voluntary manslaughter on
either theory, heat of passion or imperfect self-defense, when evidence of either is
“substantial enough to merit consideration” by the jury. (See People v. Breverman
(1998) 19 Cal.4th 142, 153–163 [77 Cal.Rptr.2d 870, 960 P.2d 1094] [discussing
charge of completed murder]; People v. Barton (1995) 12 Cal.4th 186, 201 [47
Cal.Rptr.2d 569, 906 P.2d 531] [same].)
If the victim’s gender identity or sexual orientation raises speciﬁc issues concerning
whether provocation was objectively reasonable, give an instruction tailored to
those issues on request. (Pen. Code, § 192(f), amended effective January 1, 2015.)

Speciﬁc Intent to Kill Required
An attempt to commit a crime requires an intention to commit the crime and an
overt act towards its completion. Where a person intends to kill another person
and makes an unsuccessful attempt to do so, his intention may be accompanied
by any of the aggravating or mitigating circumstances which can accompany
the completed crimes. In other words, the intent to kill may have been formed
after premeditation or deliberation, it may have been formed upon a sudden
explosion of violence, or it may have been brought about by a heat of passion
or an unreasonable but good faith belief in the necessity of self-defense.
