What is the penalty under section 667.61 of the California Penal Code for sexual assault against a minor?

Section 667.61, subdivision (m), provides that for certain felony sex offenses committed under one or more of the circumstances enumerated in the code section against a minor 14 years of age or older, the punishment is a term of 25 years to life in prison. Section 667.61 is known as the "one strike" law because it imposes life imprisonment as the punishment for certain sex offenses committed under specified circumstances, even if the defendant has no prior record. (People v. Estrada (1997) 57 Cal.App.4th 1270, 1274.)
