California Three Strikes Law

California’s Three Strikes Law can turn a single felony into 25 years to life. Our San Diego defense lawyers fight strike allegations. Call 24/7.

If you or a loved one is facing charges that carry a strike allegation, the moment you hear “three strikes,” everything changes. A conviction that might otherwise carry a few years in state prison can suddenly mean spending the rest of your life behind bars.

Most people facing strike allegations never imagined being in this situation. A bar fight that got out of hand. An accusation that doesn’t match what actually happened. A prior conviction from years ago, maybe even decades ago, that the prosecution is now using to push for a sentence that feels completely disproportionate to what you’re actually charged with today.

The reality is, a strike allegation does not automatically mean the worst-case scenario. What happens next depends on the defense you build and the attorneys standing next to you.

The fear and uncertainty are completely understandable. You’re not just facing the current charge. You’re facing the weight of prior convictions being used against you, and a sentencing structure designed to keep people in prison for as long as possible. Control what you can control. That starts with understanding the law and getting the right legal team involved immediately.

At David P. Shapiro Criminal Defense Attorneys, we’ve defended clients facing second and third strike allegations throughout San Diego County. We’ve argued Romero motions to dismiss prior strikes. We’ve negotiated plea resolutions that avoided strike convictions entirely. We know how prosecutors use this law, and we know how to challenge it.

The bottom line is this: strike cases require attorneys who understand California’s sentencing structure inside and out and who will actually fight to keep you out of prison for the rest of your life.

Quick Reference: California Three Strikes Law

What Is the Three Strikes Law?

California’s Three Strikes Law is one of the most consequential sentencing laws in the country. Enacted in 1994, it was designed to impose increasingly severe prison sentences on repeat offenders convicted of serious or violent felonies.¹

What does that actually mean in practice? Well, it means that your criminal history can dramatically increase the prison sentence you face on a new charge. Not because the new charge is more serious, but because of what happened before.

The law operates under two parallel statutes. Penal Code Section 667, subdivisions (b) through (i), was enacted by the Legislature.² Penal Code Section 1170.12 was enacted by the voters through Proposition 184 the same year.³ Both statutes accomplish the same thing, they just arrived through different channels. Courts apply whichever produces the harsher result.

The critical concept is the “strike.” A strike is a prior conviction for a crime that California classifies as either a “serious felony” or a “violent felony.” Those classifications are defined in two specific Penal Code sections, and the list of qualifying offenses is long.

What Counts as a Strike?

Two categories of felonies qualify as strikes under California law: violent felonies and serious felonies. Understanding these categories is essential because the consequences of a strike allegation depend entirely on whether the prior conviction actually qualifies.

Violent Felonies (PC 667.5(c))

Violent felonies are defined under Penal Code Section 667.5, subdivision (c).⁴ These are always strikes. The list includes:

• Murder and attempted murder
• Voluntary manslaughter
• Robbery and carjacking
• Kidnapping
• Rape and forcible sexual offenses
• Lewd acts on a child under 14
• Arson of an inhabited structure
• Mayhem
• Any felony in which the defendant personally used a firearm
• Any felony in which the defendant inflicted great bodily injury

Serious Felonies (PC 1192.7(c))

Serious felonies are defined under Penal Code Section 1192.7, subdivision (c).⁵ This list is even broader. It includes all violent felonies plus:

• Assault with a deadly weapon
• Criminal threats
• First-degree burglary (residential)
• Grand theft involving a firearm
• Battery causing serious bodily injury
• Many drug trafficking offenses
• Any felony in which the defendant personally used a dangerous or deadly weapon

What does this mean for your case? Well, if you have a prior conviction for any offense on either of these lists, the prosecution can allege that conviction as a “strike” and seek enhanced sentencing on your current charge. Even if the prior is from 10, 15, or 20 years ago.

Second Strike: What Happens With One Prior

A second strike doubles the punishment. If you have one prior strike conviction and you’re convicted of any new felony, serious or not, the sentence on the new felony is presumptively doubled.⁶

Here’s what that looks like in practice. Say you have a prior robbery conviction from 2010. Now you’re charged with a felony that normally carries a sentence of 2, 3, or 4 years. With the strike prior, that range becomes 4, 6, or 8 years. The court must impose the doubled sentence unless the judge exercises discretion to dismiss the strike.

Additional second-strike consequences:

• You must serve at least 80% of the doubled sentence before becoming eligible for parole⁷
• Probation is not available for many second-strike offenses
• The sentence is served consecutively with any other counts, not concurrently
• Good-time credits are significantly limited

The prosecution doesn’t have to prove anything new about the prior conviction at trial. They prove the current charge, and then they prove the prior strike exists, usually through certified court records or “prison packets.”

Third Strike: 25 Years to Life

A third strike triggers the harshest consequence in California’s sentencing scheme. If you have two or more prior strike convictions and you’re convicted of a new felony, the sentence is 25 years to life in state prison.⁸

Before Proposition 36 in 2012, this applied regardless of whether the new felony was serious or violent. Someone could receive 25 years to life for shoplifting if they had two prior strikes. That changed.

Post-Prop 36 Rules (Current Law)

Under Proposition 36, the 25-years-to-life sentence now applies only when the new (third) felony is itself a serious or violent felony.⁹ If the new felony is not serious or violent, the sentence is simply doubled (treated as a second strike) rather than triggering the indeterminate life term.

There are exceptions. Even if the new offense is not serious or violent, the 25-to-life sentence can still apply if:

• The new offense involved firearm possession or use
• The new offense involved intent to cause great bodily injury
• A prior strike was for a sexually violent offense under Welfare and Institutions Code Section 6600(b)

Prop 36 Resentencing (PC 1170.126)

Proposition 36 also created a resentencing mechanism for people already serving 25-to-life sentences under the old rules.¹⁰ If the third-strike offense was not serious or violent, and none of the disqualifying exceptions apply, they can petition the court for resentencing to a second-strike term.

Thousands of people across California have been resentenced under this provision. For all intents and purposes, Prop 36 retroactively changed the deal for people who were sentenced under the old, harsher version of the law. (For more on eligibility and the petition process, see our Proposition 36 Resentencing page.)

Sentencing Enhancements That Stack With Strikes

Strike allegations don’t exist in a vacuum. They’re often combined with additional sentencing enhancements that can push the total sentence even higher.

Firearm use (PC 12022.53): The “10-20-Life” law adds consecutive time for firearm involvement.¹¹ Personally using a firearm adds 10 years. Discharging it adds 20. Causing death or great bodily injury with a firearm adds 25 years to life. These are served on top of the strike sentence.

Prior serious felony (PC 667(a)): A prior serious felony conviction adds 5 years, served consecutively.¹² This is separate from the strike enhancement and stacks on top of it. So someone facing a third strike with a prior serious felony enhancement could face 25-to-life plus an additional 5 years before becoming parole eligible.

Gang enhancement (PC 186.22): If the offense was committed for the benefit of a criminal street gang, additional consecutive terms of 15 years to life can apply.¹³

You can see how these things snowball. A single charge with a strike allegation and stacking enhancements can result in an effective sentence that means someone will spend the rest of their natural life in prison.

Defense Strategies for Three Strikes Cases in San Diego

Strike cases are among the most consequential in criminal law, and they require defense strategies that go beyond just fighting the current charge. We can, and will, challenge the strike allegations themselves if the facts support a position to do so. Here are the approaches we consider:

The Romero Motion: Asking the Court to Dismiss a Strike

In People v. Superior Court (Romero), the California Supreme Court held that trial judges have the discretion to dismiss, or “strike,” prior strike convictions in the furtherance of justice under Penal Code Section 1385.¹⁴

What does the court look at? The nature and circumstances of the current offense, the defendant’s background and character, the age and nature of the prior strike convictions, and whether the defendant falls outside the spirit of the Three Strikes Law. This is a case-by-case analysis, and judges have significant latitude.

A successful Romero motion can be the difference between 25 years to life and a determinate sentence. It’s one of the most powerful tools in strike defense, and it requires thorough preparation. We’ve argued Romero motions throughout San Diego County, and we know what courts look for.

Challenging the Prior Strike Itself

Not every prior conviction actually qualifies as a strike. We examine the record of conviction, the charging documents, plea transcripts, and jury instructions from the prior case. If the prior offense can be interpreted in a way that doesn’t meet the definition of a serious or violent felony, the strike allegation fails.

This is particularly relevant for wobbler offenses and offenses where the “serious” or “violent” classification depends on specific factual findings (like personal use of a weapon or infliction of great bodily injury) that may not have been made in the prior case.

Proposition 36 Resentencing Petition

If you’re currently serving a 25-to-life sentence and your third strike was not a serious or violent felony, you may be eligible for resentencing under PC 1170.126.¹⁵ The petition process requires demonstrating that you meet the statutory criteria and that resentencing would not pose an unreasonable risk of danger to public safety.

Negotiating a Non-Strike Resolution

In some cases, the strongest defense strategy involves negotiating with the prosecution to resolve the current charge in a way that avoids the strike enhancement altogether. This could mean pleading to a lesser offense that doesn’t carry a strike, or persuading the prosecution to withdraw the strike allegation as part of a plea resolution.

The prosecution has discretion in alleging and proving strikes. Presenting a compelling case for why the strike allegation is disproportionate, or why the prior conviction doesn’t warrant the enhancement, can influence how the DA handles the case.

Challenging the Current Charge

Every element of the current offense is a potential avenue for defense. If we can defeat the underlying charge, the strike allegation becomes irrelevant. We look at the evidence, witnesses, forensic material, constitutional issues with how evidence was obtained, and every other factor that might create reasonable doubt.

The burden is on the prosecution to prove the current offense beyond a reasonable doubt. That remains true regardless of how many prior strikes exist.

Facing Three Strikes Charges in San Diego?

When the prosecution alleges a strike enhancement, they’re signaling that they want you in prison for as long as the law allows. These cases require attorneys who understand California’s sentencing structure at the deepest level, who know how to argue Romero motions, and who can dissect prior convictions to determine whether they actually qualify as strikes.
