California's Three Strikes sentencing law was originally enacted in 1994. The essence of the Three Strikes law was to require a defendant convicted of any new felony, having suffered one prior conviction of a serious felony to be sentenced to state prison for twice the term otherwise provided for the crime. If the defendant was convicted of any felony with two or more prior strikes, the law mandated a state prison term of at least 25 years to life.
On November 6, 2012 the voters approved Proposition 36 which substantially amended the law with two primary provisions:
The Amendment of the Three Strikes Sentencing Law (February 2016) by J. Richard Couzens, Judge of the Superior Court of Placer County(Ret.) and Presiding Justice Tricia A. Bigelow, Court of Appeal, 2nd Appellate District, Div. 8
