Under California’s Three Strikes law, a new felony conviction is punished more harshly if the defendant already has prior convictions for certain serious or violent felonies. One prior strike doubles the sentence on the new felony. Two or more prior strikes bring a minimum of 25 years to life, though a 2012 voter reform limited that life term to cases where the new felony is itself serious or violent, or where a “super strike” sits on the record.1Legislative Analyst’s Office. A Primer: Three Strikes – The Impact After More Than a Decade
Which Prior Convictions Count as Strikes
Not every felony qualifies. A prior counts as a strike only if it appears on one of two statutory lists: the violent felonies in Penal Code 667.5(c) or the serious felonies in Penal Code 1192.7(c). The violent list includes murder, voluntary manslaughter, rape, robbery, kidnapping, carjacking, arson of an inhabited structure, attempted murder, continuous sexual abuse of a child, and any felony where the defendant personally inflicted great bodily injury or used a firearm.2California Legislative Information. California Penal Code 667.5 The serious list in 1192.7(c) overlaps substantially and adds offenses like first-degree burglary, grand theft involving a firearm, threatening a witness, and assault with a deadly weapon.3California Legislative Information. California Penal Code 1192.7 If an offense is on either list, it counts.
Prior convictions from other states can qualify, but only if the out-of-state offense would have been a California prison felony and its elements match a California serious or violent felony. Courts compare elements, not labels. A conviction called “robbery” in another state qualifies only if that state defines robbery with the same elements California does.4California Legislative Information. California Penal Code 667
Juvenile adjudications can also count. The defendant must have been at least 16 at the time of the offense, the offense must qualify as a serious or violent felony, and the juvenile must have been adjudged a ward of the court for an offense listed in the Welfare and Institutions Code.4California Legislative Information. California Penal Code 667 These technical requirements are often contested, since juvenile records can be incomplete or sealed.
Second Strike Sentences
A defendant with one prior strike who is convicted of any new felony has the normal prison term for that new felony doubled. A four-year offense becomes eight. A three-year offense becomes six. The new felony does not have to be serious or violent for the doubling to apply. Any felony triggers it.4California Legislative Information. California Penal Code 667
Credits are also restricted. Good-behavior credits are capped at one-fifth of the total sentence, so a second striker must serve at least 80% of the doubled term before release. A doubled eight-year sentence means roughly six and a half years in custody at a minimum, compared to a much shorter stretch for a first-time offender convicted of the same crime.4California Legislative Information. California Penal Code 667
Third Strike Sentences After the 2012 Reform
Before November 2012, two or more prior strikes plus any new felony conviction, however minor, meant an automatic 25 years to life. That rule produced life sentences for shoplifting and for simple drug possession when the defendant had two old strikes.1Legislative Analyst’s Office. A Primer: Three Strikes – The Impact After More Than a Decade
Proposition 36 narrowed the trigger. The 25-years-to-life sentence now applies only when the new felony is itself a serious or violent felony. If the new offense is non-serious and non-violent, the defendant is sentenced as a second striker, meaning the normal term is doubled rather than replaced with a life sentence.5Legislative Analyst’s Office. Proposition 36 – Three Strikes Law. Sentencing for Repeat Felony Offenders
Two sets of exceptions preserve the life term even when the new felony is minor. The first covers specific dangerous factors tied to the current offense: using a firearm, intending to cause great bodily harm, or committing a sex offense requiring registration. The second covers defendants with a super strike on their record.
Super Strikes
Super strikes are a defined group of prior convictions severe enough to disqualify the defendant from the Proposition 36 benefit entirely. A single super strike on the record locks in 25 years to life even when the current felony is minor. The categories under Penal Code 667(e)(2)(C)(iv) are:6California Legislative Information. California Penal Code 667
- Sexually violent offenses as defined in Welfare and Institutions Code 6600(b).
- Sex crimes against children under 14 who are more than 10 years younger than the defendant, including oral copulation, sodomy, and sexual penetration.
- Lewd or lascivious acts with a child under 14.
- Any homicide offense, including attempted murder and all offenses defined in Penal Code 187 through 191.5.
- Solicitation to commit murder.
- Assault with a machine gun on a peace officer or firefighter.
- Possession of a weapon of mass destruction.
- Any serious or violent felony punishable by life imprisonment or death.
The effect is stark. A defendant with a decades-old murder conviction who is caught shoplifting a qualifying felony amount can still face 25 to life, while the same shoplifting charge would bring a doubled term for someone whose prior strikes were, say, two robberies.7County of San Diego.

Asking the Judge to Dismiss a Strike: Romero Motions
Even where the statutory formula calls for a doubled or life term, the sentencing judge has authority to dismiss one or more prior strike allegations “in furtherance of justice” under Penal Code 1385. The California Supreme Court confirmed this power in People v. Superior Court (Romero) in 1996, and defense requests to use it are known as Romero motions.8Justia Law. People v. Superior Court (Romero)
Two years later, People v. Williams set the framework. The judge weighs the nature of the current felony, the nature of the prior strikes, and the defendant’s background, character, and prospects, asking whether the defendant falls outside the spirit of the Three Strikes scheme and should be treated as if the prior strike were not there.9Justia Law. People v. Williams
In practice, judges look hard at how old the strike is and what the defendant has done since. A 20-year-old robbery followed by decades of law-abiding life makes a stronger case than a recent violent felony followed by another one. The severity of the current offense cuts the other way: dismissing a strike is harder to justify when the new crime is dangerous. Prosecutors routinely oppose these motions, so defense counsel typically presents detailed mitigating evidence on employment, family ties, treatment, and rehabilitation. Rulings on either side can be appealed, but appellate courts review for abuse of discretion, which gives the trial judge wide latitude.
Resentencing If You’re Already Serving a Third-Strike Life Term
Proposition 36 was partially retroactive. Under Penal Code 1170.126, a person currently serving a 25-to-life third-strike sentence can petition the original trial court to recall the sentence and resentence them under the reformed rules.10California Legislative Information. California Penal Code 1170.126
Three conditions have to be met. The inmate must be serving the life term for a felony that is not serious or violent. The current offense must not involve any of the disqualifying factors that would trigger a life sentence under the new rules, such as firearm use or a registrable sex offense. And the inmate must not have a super strike on the record. Even if all three conditions are met, the court can still deny the petition if resentencing would pose an unreasonable risk of danger to public safety.10California Legislative Information. California Penal Code 1170.126
The original filing window was two years after Proposition 36 took effect, but courts can accept late petitions on a showing of good cause.
The Five-Year Serious Felony Enhancement
Separate from the strike-doubling and life-sentence provisions, a defendant currently convicted of a serious felony picks up a consecutive five-year prison term for each prior serious felony conviction. Multiple priors stack. Three prior serious felonies can add 15 years on top of the base sentence.
SB 1393, effective January 1, 2019, restored judicial discretion to strike this enhancement in the interest of justice on a case-by-case basis.4California Legislative Information. California Penal Code 667 Before 2019, imposition was mandatory.
Don’t Confuse This With the 2024 Proposition 36
California voters passed a different measure also called Proposition 36 in November 2024. It has nothing to do with the Three Strikes reform. The 2024 law toughened penalties for certain theft and drug offenses, partially rolling back Proposition 47. It made shoplifting a potential felony for people with two or more prior theft convictions, allowed longer sentences for group thefts, created “treatment-mandated felonies” for certain repeat drug offenders, and added fentanyl to the list of drugs that trigger felony charges when possessed with a loaded firearm.11Legislative Analyst’s Office. Proposition 36 It did not change the strike-sentencing structure, but a new felony it creates can still trigger second-strike doubling for anyone who already carries a strike.
