California Three Strikes Law: Sentencing, Priors, and Resentencing

Under the California Three Strikes law, a new felony conviction carries double the normal prison term if the defendant already has one prior conviction for a serious or violent felony, and a minimum of 25 years to life if the defendant has two or more such priors and the new felony is itself serious or violent.¹ Proposition 36, passed by voters in November 2012, narrowed the life-sentence trigger so that in most cases the new felony itself must be serious or violent before 25 to life applies.² Several exceptions keep the old life-sentence rule alive for certain offenses and offenders, and judges have real discretion to dismiss strike priors in appropriate cases.

What Counts as a Strike

A strike is a prior conviction for either a serious felony listed in Penal Code Section 1192.7(c) or a violent felony listed in Section 667.5(c). The two lists overlap heavily but are not identical.

Serious felonies include murder, voluntary manslaughter, rape, robbery, kidnapping, first-degree burglary, arson, carjacking, assault with a deadly weapon on a peace officer, selling specified drugs to a minor, any felony in which the defendant personally used a firearm or inflicted great bodily injury, and any felony committed in connection with a criminal street gang. The full list runs more than 40 offenses.³

Violent felonies include murder, voluntary manslaughter, mayhem, rape, certain sex offenses against children, robbery, arson, kidnapping, carjacking, attempted murder, continuous sexual abuse of a child, and any felony punishable by life or death, along with felonies involving great bodily injury or specified firearm use.⁴

The violent-versus-serious distinction matters even once something counts as a strike. First-degree burglary is always serious, but it only becomes violent if someone other than an accomplice was present in the residence. That shifts how much good-conduct credit the inmate can earn and whether certain post-conviction relief is available.

Strike priors never wash out. A conviction from 30 years ago counts the same as one from last year, and the gap between the old case and the new one does not limit the court.⁵

Second-Strike Sentencing

If you have one prior strike and are convicted of any new felony, you are a second striker. The new felony does not have to be serious or violent. The court takes the prison term it would otherwise impose for the new offense and doubles it.⁶ A four-year sentence becomes eight. Because the court doubles whichever term it picks from the low-middle-upper triad, the base-term decision carries extra weight.

Under SB 567, the court generally cannot select the upper term unless aggravating factors have been found true beyond a reasonable doubt or stipulated to, though prior convictions can be considered on a certified record. The court must select the lower term if the offense was connected to childhood trauma, youth, or intimate partner violence, unless aggravating circumstances clearly outweigh that factor.⁷

If a second striker is convicted of multiple felony counts arising from separate occasions or separate sets of facts, the court must run the sentences consecutively.⁷ Two burglaries on two different days each get their own doubled term, back to back.

Time actually served depends on the current offense. Second strikers whose current conviction is a violent felony earn good-conduct credit at one day for every two served, so they serve roughly 75 percent of the total. Second strikers convicted of a non-violent felony earn credit at one day for each day served and serve roughly 67 percent.⁸

Third-Strike Sentencing

Two or more prior strikes plus a new serious or violent felony conviction produces an indeterminate life sentence. The minimum term before parole eligibility is the greatest of:

Three times the base term for the current felony,
25 years, or
The full determinate term the court would otherwise impose, including any applicable enhancements.

Whichever number is largest controls.⁶ For many offenses, 25 years is the floor. For crimes with longer base terms, the triple-the-term formula can push the minimum higher. A current conviction carrying a nine-year base term produces a 27-year minimum.

A third-strike life term runs consecutively to any other sentence. Probation is not available, and parole consideration begins only after the minimum has been served.

When a Third Strike Still Triggers Life Despite a Minor Current Felony

Before Proposition 36, any felony could be the third strike. Shoplifting or simple drug possession could produce 25 to life. Proposition 36 generally requires the current felony to be serious or violent before the life term kicks in. When it isn’t, the defendant is sentenced as a second striker with a doubled term instead.⁹

But Proposition 36 kept several exceptions. A life term can still be imposed on a defendant with two prior strikes even when the current offense is not serious or violent if, during the current case, any of the following is true:

The current offense is a controlled substance charge involving specified quantity-based allegations.
The current offense is a felony sex offense requiring sex offender registration.
The defendant used a firearm, was armed with a firearm or deadly weapon, or intended to cause great bodily injury during the current offense.⁶

A separate set of exceptions looks at the priors, not the current case. If any prior strike is a “super strike,” the defendant faces life for any new felony, no matter how minor. Super strikes include any sexually violent offense; certain sex crimes against a child under 14 who is more than 10 years younger than the defendant; lewd or lascivious acts with a child under 14; any homicide or attempted homicide; solicitation to commit murder; assault with a machine gun on a peace officer or firefighter; possession of a weapon of mass destruction; and any serious or violent felony punishable by life or death.¹⁰ A defendant with a super strike prior is effectively treated under the pre-2012 version of the law.

How Priors From Elsewhere and From Juvenile Court Count

Out-of-state and federal convictions can qualify as California strikes, but the match has to be close. The offense must have been punishable by state prison if committed in California, and it must contain all the elements of a California serious or violent felony.⁷ A federal robbery is tested element by element against California robbery, not by name. If the outside statute is broader and could be violated in ways California’s wouldn’t reach, it may not count.

Juvenile adjudications can count as strikes only when all three of the following are true: the minor was 16 or 17 at the time of the offense; the offense is listed as a serious or violent felony; and the offense also appears on the Welfare and Institutions Code Section 707(b) transfer list.¹⁰ A juvenile adjudication dismissed under Welfare and Institutions Code Section 782 before the new adult offense cannot be used. An expungement under Section 1772, however, does not prevent a juvenile adjudication from counting.

The Added Five-Year Serious Felony Enhancement

Separate from the doubling rule and the life term, Penal Code Section 667(a)(1) adds a five-year consecutive enhancement for each prior serious felony conviction, if the current conviction is also a serious felony and the priors were brought and tried separately.⁷ Two qualifying priors mean ten extra years stacked on top of everything else.

The enhancement used to be mandatory. A legislative change effective in 2019 lifted that bar, and judges now have discretion to dismiss it in the furtherance of justice.¹¹ For a second striker facing a doubled six-year term plus two five-year enhancements, the difference between striking the enhancements and letting them stand is ten years.

Ways a Strike Can Be Dismissed

California judges can strike a prior conviction for sentencing purposes under Penal Code Section 1385 through what defense lawyers call a Romero motion, named after the 1996 California Supreme Court decision that confirmed the authority.¹¹ Striking one prior turns a third striker into a second striker. Striking both leaves the defendant to be sentenced as a first-time felon.

The court weighs the defendant’s criminal history and background, the nature of the current offense, the prospects for rehabilitation, and the circumstances in aggravation and mitigation to decide whether the defendant falls outside the spirit of the Three Strikes law.¹² Old priors and a minor current offense help. Recent priors and a serious new charge hurt. The judge must put the reasons on the record.

SB 81, effective January 1, 2022, added a presumption favoring dismissal of enhancements when any of the following mitigating circumstances is present:¹¹

The enhancement rests on a prior conviction more than five years old.
Multiple enhancements are alleged in a single case.
The enhancement could push the total sentence past 20 years.
The current offense is connected to mental illness, childhood trauma, or prior victimization.
The defendant was a juvenile at the time of the current offense or any prior offense triggering the enhancement.
The current offense is not a violent felony.

Unless dismissal would endanger public safety, the law directs the court to dismiss. SB 81 does not apply where dismissal is prohibited by an initiative statute, and because the Three Strikes law was enacted both legislatively and through Proposition 184, whether SB 81’s presumption applies directly to strike priors remains contested. Either way, these same factors inform a Romero analysis, and defense attorneys lean on them.

Prosecutors can also move to dismiss strike priors in the furtherance of justice, and this is more common than many defendants assume. The Legislative Analyst’s Office found that prior strikes were dismissed in roughly 25 to 45 percent of third-strike cases in some counties, producing significant variation across California.⁵

Resentencing for People Already Serving Pre-2012 Life Terms

Proposition 36 also reaches backward. Under Penal Code Section 1170.126, an inmate serving an indeterminate life term for a third-strike conviction can petition the original trial court to recall the sentence if the triggering felony was not serious or violent.¹³

Eligibility also requires that the inmate not have a super strike prior and not have a current offense in the excluded categories (sex offenses requiring registration, the specified drug charges, or offenses involving firearms or great bodily injury). If the court finds the petitioner eligible, it resentences them as a second striker unless release would pose an unreasonable risk of danger to public safety. The court looks at the petitioner’s full criminal history, prison disciplinary record, rehabilitation evidence, and any other relevant information. The original two-year filing window has closed, but courts can accept later petitions for good cause.
