California Penal Code Section 667(d)(3)
Penal Code Section 667, subdivision (d)(3) provides:
"A prior juvenile adjudication shall constitute a prior felony conviction for purposes of sentence enhancement if: (A) The juvenile was 16 years of age or older at the time he or she committed the prior offense. (B) The prior offense is listed in subdivision (b) of Section 707 of the Welfare and Institutions Code or described in paragraph (1) or (2) as a felony. (C) The juvenile was found to be a fit and proper subject to be dealt with under the juvenile court law. (D) The juvenile was adjudged a ward of the juvenile court within the meaning of Section 602 of the Welfare and Institutions Code because the person committed an offense listed in subdivision (b) of Section 707 of the Welfare and Institutions Code."
The list of offenses in Welfare and Institutions Code section 707, subdivision (b) includes "assault with a firearm or destructive device" and "assault by any means of force likely to produce great bodily injury." (Welf. & Inst. Code, 707, subd. (b)(13) & (14).) It does not include assault with a deadly weapon.
To prove the "strike" allegation, the prosecution introduced the Welfare and Institutions Code section 602 petition in the prior juvenile case, which alleged that defendant committed "an assault upon the victim with a deadly weapon, to wit: a knife, and by means of force likely to produce great bodily injury, thereby violating Section 245(a) . . . ."
