California Three Strikes Law

California Three Strikes Law
By: Tammy HigginsJuly 27, 2026

California's Three Strikes Law stands as one of the harshest sentencing statutes in the country. Enacted in 1994 and later reshaped through Proposition 36 in 2012, it altered how courts sentence defendants with prior convictions across the state, including those in Los Angeles County that oversee cases from West Covina and nearby communities.

A recognized defense lawyer in West Covina often points out that grasping how this law functions, what qualifies as a strike, and what choices remain available for someone facing a second or third strike charge isn't just a matter of legal theory For many people caught in the system, it can mean the difference between a sentence they can survive and decades behind bars in a state prison. 



What the Three Strikes Law Actually Does

California Penal Code 667 and PC 1170.12 together form the Three Strikes Law. A defendant with one prior serious or violent felony conviction who is then convicted of any new felony faces a sentence that is doubled from the base term. A defendant with two prior serious or violent felony convictions who is then convicted of a new serious or violent felony faces a minimum sentence of 25 years to life in state prison.

The law was designed to target repeat violent offenders, though its application before the 2012 reform produced outcomes many California voters found disproportionate. Proposition 36 brought the structure more in line with that original intent by limiting the mandatory 25-to-life sentence to cases where the third strike is itself a serious or violent felony. Even after the reform, the law remains one of the most powerful sentencing tools the state has, and it affects how defense attorneys have to approach any new felony case for a client with prior strikes on their record.


What Counts as a Strike in California

Not every felony conviction is a strike. California law designates specific offenses as strikes under PC 667(d) and the serious felony list in PC 1192.7(c), which includes residential burglary, robbery, rape, certain assault charges, arson, and kidnapping, among others. Violent felonies under PC 667.5(c) separately cover murder, voluntary manslaughter, attempted murder, and rape. Whether a prior conviction qualifies depends on the exact charge and the facts of that conviction, not just its label.

A prior conviction counts as a strike regardless of when or where it occurred, and out-of-state convictions can qualify if the offense would meet California's own definitions of serious or violent felony. Juvenile adjudications can sometimes count as strikes as well, depending on the age of the defendant and the nature of the offense. This surprises many defendants who assumed their juvenile record would have no bearing on adult sentencing. It is one of the first things we look at when we take on a case for someone with prior criminal history.


How the Second Strike Changes Sentencing

A second-strike defendant in California faces a doubled sentence on any new felony conviction. If the base term for the new felony is four years, the second-strike calculation makes it eight. The defendant must also serve at least 80 percent of that sentence before being eligible for release, compared to 50 percent for a standard felony sentence. The second-strike enhancement applies to any new felony conviction, not just serious or violent ones.

This is one of the reasons why getting aggressive about fighting new charges matters so much for anyone who already has a strike on their record. A conviction that might result in probation for a first-time offender can result in significant prison time for someone with a prior strike. The difference in outcome between a conviction and an acquittal, or between a felony and a misdemeanor conviction, is dramatic when a second strike is in play. Our violent crimes defense practice handles exactly these situations.


Third Strike and the Path to 25 Years to Life

After the 2012 Proposition 36 reform, a third-strike sentence of 25 years to life is triggered when the third felony conviction is itself a serious or violent felony under California law. If the third strike is a nonviolent felony, the defendant is sentenced as a second-strike offender rather than receiving the mandatory 25-to-life term, unless specific exceptions apply.

Those exceptions matter. Even after the reform, a defendant can still face 25 years to life on a third non-serious or non-violent felony if the current offense involves a firearm, the defendant is required to register as a sex offender, the current offense caused great bodily injury or death, or the defendant has prior convictions for specific serious crimes including murder and rape. These exceptions are complex, and their application turns on facts that require careful analysis from the very start of the case.


The 2012 Proposition 36 Reform and Who It Helped

Proposition 36, passed by California voters in November 2012, made two major changes. Going forward, the mandatory 25-to-life sentence on a third strike was limited to cases where the third felony is serious or violent, with the exceptions noted above. Retroactively, inmates already serving life sentences under the pre-reform law for non-serious or non-violent third strikes were given the right to petition the court for resentencing under the new standards.

Thousands of defendants benefited from retroactive resentencing after 2012, and some remain eligible today. If someone you know is serving a life sentence triggered by a non-serious or non-violent third strike under the old law, a resentencing petition under the current standards may be worth pursuing. Our resentencing practice covers these matters alongside our active criminal defense work, and the results in some of these cases have been significant for the people and families involved.


Fighting a Strike Prior and Seeking Resentencing in West Covina

There are several ways our team approaches Three Strikes cases in active criminal proceedings. We look at whether prior convictions were correctly designated as strikes, whether the prior plea was knowing and voluntary, and whether the strike prior can be challenged on legal grounds. Judges in California also have discretion to dismiss a strike prior in the interest of justice under the Romero rule (People v. Superior Court), and we press for that consideration whenever the facts and the client's history support it. Our case results show how post-conviction work has played out across a range of charge types.

Our resentencing practice sits alongside our active criminal defense work, which means we see these cases from the initial charge all the way through post-conviction relief. For clients facing a strike charge in West Covina or anywhere in Los Angeles County, that perspective makes a real difference in how the case gets handled.
