Michael M. v. Superior Court of Sonoma County

Petitioner, then a 17 1/2-year-old male, was charged with violating California's "statutory rape" law, which defines unlawful sexual intercourse as "an act of sexual intercourse accomplished with a female not the wife of the perpetrator, where the female is under the age of 18 years." Prior to trial, petitioner sought to set aside the information on both state and federal constitutional grounds, asserting that the statute unlawfully discriminated on the basis of gender since men alone were criminally liable thereunder.

One of the purposes of the California statute in which the State has a strong interest is the prevention of illegitimate teenage pregnancies. The statute protects women from sexual intercourse and pregnancy at an age when the physical, emotional, and psychological consequences are particularly severe. Because virtually all of the significant harmful and identifiable consequences of teenage pregnancy fall on the female, a legislature acts well within its authority when it elects to punish only the participant who, by nature, suffers few of the consequences of his conduct.
