intent or mental state or involves only offenses that do not. (See CALCRIM No.
250, Union of Act and Intent: General Intent, and CALCRIM No. 251, Union of Act
and Intent: Specific Intent or Mental State.)
The court should specify for the jury which offenses require general criminal intent
and which require a specific intent or mental state by inserting the names of the
offenses where indicated in the instruction. (See People v. Hill (1967) 67 Cal.2d
105, 118 [60 Cal.Rptr. 234, 429 P.2d 586].) If the crime requires a specific mental
state, such as knowledge or malice, the court must insert the name of the offense in
the third paragraph, explaining the mental state requirement, even if the crime is
classified as a general intent offense.
If the defendant is charged with aiding and abetting or conspiracy to commit a
general-intent offense, the court must instruct on the specific intent required for
aiding and abetting or conspiracy. (See People v. McCoy (2001) 25 Cal.4th 1111,
1117-1118 [108 Cal.Rptr.2d 188, 24 P.3d 1210]; People v. Bernhardt (1963) 222
Cal.App.2d 567, 586-587 [35 Cal.Rptr. 401].)
If the defendant is also charged with a criminal negligence or strict-liability offense,
insert the name of the offense where indicated in the first sentence. The court may
also give CALCRIM No. 253, Union of Act and Intent: Criminal Negligence, or
CALCRIM No. 254, Union of Act and Intent: Strict-Liability Crime.
Defenses - Instructional Duty
Evidence of voluntary intoxication or mental impairment may be admitted to show
that the defendant did not form the required mental state. (See People v. Ricardi
(1992) 9 Cal.App.4th 1427, 1432 [12 Cal.Rptr.2d 364].) The court has no sua sponte
duty to instruct on these defenses; however, the trial court must give these
instructions on request if supported by the evidence. (People v. Saille (1991) 54
Cal.3d 1103, 1119 [2 Cal.Rptr.2d 364, 820 P.2d 588]; see Defenses and Insanity,
CALCRIM No. 3400 et seq.)
