California’s Three Strikes law increases prison sentences for people who already have one or more convictions the state classifies as serious or violent felonies. Voters approved it as Proposition 184 in November 1994, and the Legislature enacted a nearly identical version earlier that same year. Its effect is to turn what looks like an ordinary felony charge into a case with decades on the line. If you or someone in your family is facing charges with a prior strike on the record, a Walnut Creek criminal defense attorney can explain how the law applies to the specific priors involved.
Which Prior Convictions Count as a Strike
A prior conviction counts as a strike only if California defines it as a violent or serious felony. Those two lists sit in separate parts of the Penal Code, and the California Supreme Court pointed to both of them when it explained how the law operates. A felony that falls outside both lists does not create a strike.
Two features of the rule catch people off guard:
- Age does not matter. A qualifying prior counts no matter how many years have passed since the conviction.
- A new charge does not have to be serious or violent. Under the law as originally written, any new felony triggered the enhanced sentencing scheme.
Those two features are why a burglary from decades ago can reshape a case that looks minor on its face today.
How Second Strike and Third Strike Sentences Work
With one qualifying prior, the sentence for the new felony is twice the term the law otherwise sets for that offense. Under the law as originally enacted, two or more qualifying priors produced an indeterminate life term. Voters narrowed that rule in 2012 in the way described in the next section. Where a life term still applies, parole eligibility is measured from a minimum term, calculated as the greatest of three times the term for the current offense, 25 years, or the term required by California’s other sentencing statutes.
The law also strips away options a judge would normally have. Probation is unavailable for the current offense, sentences on multiple current offenses generally run consecutively, and the court cannot commit the defendant to any facility other than state prison. That combination is what makes a strike allegation so much more serious than a standard sentencing enhancement.
What Proposition 36 Changed in 2012
California voters narrowed the law in November 2012. Under the change, a person with two or more prior serious or violent felony convictions whose new offense is nonserious and nonviolent generally receives twice the usual term for that offense instead of a minimum of 25 years to life. According to the state’s official fiscal analysis of that measure, the change was expected to reduce the sentences of some future felony offenders and to result in many existing inmates receiving shorter prison terms.
The narrowing is not absolute. Certain new or prior offenses, including specified drug, sex, and gun-related felonies, still carry a life sentence. The 2012 measure also created a court process allowing some people already serving third strike life terms to petition for resentencing, with a court required to grant relief to an eligible petitioner unless resentencing would pose an unreasonable risk to public safety. Eligibility for that process is narrow and technical.
Since 2012, the strike framework itself has stayed largely in place. The most recent major sentencing initiative, Proposition 36 of 2024, dealt with drug and theft offenses rather than with strikes.
Can a Judge Remove a Strike From Your Case
Sometimes, yes. Penal Code Section 1385 allows a judge to dismiss an allegation in furtherance of justice, and in 1996 the California Supreme Court held that this power survives in Three Strikes cases. The judge can act on the prosecutor’s motion or on the court’s own motion. Defense attorneys generally call the request a Romero motion, after that decision.
The discretion is real, but it has boundaries. The court must weigh both the constitutional rights of the defendant and the interests of society, and the reasons for the decision have to be stated on the record so an appellate court can review them. A judge who strikes a prior only to relieve a crowded calendar, or simply because the defendant pleaded guilty, abuses that discretion.
One further point matters a great deal. Striking a prior does not erase it. In the same decision, the California Supreme Court repeated its earlier holding that an order striking a prior conviction allegation does not wipe out the conviction or prevent it from being considered in connection with later convictions.
Can a Strike Be Expunged in California
No. The judicial branch’s own guide to cleaning a criminal record states plainly that true expungement does not exist in California. What the state offers instead is a set of narrower remedies that reduce the weight of a record without erasing it.
Those remedies include the following:
- Dismissal under Penal Code Section 1203.4 once probation has been completed or terminated early
- Discretionary dismissal of a felony that carried a state prison sentence, available two years after the sentence is complete in cases that do not require sex offender registration
- Reduction of a qualifying wobbler felony to a misdemeanor under Penal Code Section 17(b)
- Reduction of certain older drug and low value theft felonies to misdemeanors under Proposition 47
Each of these carries strict eligibility rules, and none of them works like the clean slate most people picture. Section 1203.4 says as much in its own text. In any later prosecution for another offense, the prior conviction may still be pleaded and proved, and it carries the same effect as if the case had never been dismissed.
Whether any other form of relief changes how a prior is treated in a future case is a fact specific question worth raising with a lawyer before you file anything. In practice, that is why the stronger play in a case involving a strike is almost always to fight the strike allegation now rather than to plan on clearing it later.
