You cannot expunge a strike in California in the ordinary sense of the word. A standard expungement under Penal Code 1203.4 dismisses the conviction for many purposes but leaves the strike fully usable against you in any future prosecution. To actually neutralize a strike, you need a different tool: a Romero motion to have a judge disregard the strike when sentencing you on a new felony, a Penal Code 17(b) reduction to convert a qualifying felony to a misdemeanor (which strips it of strike status), or resentencing under Proposition 36 or Proposition 47. Which one applies depends on the offense, your record, and whether you are currently facing charges or serving time.
Why 1203.4 Expungement Doesn’t Remove a Strike
This is where most people get tripped up. Penal Code 1203.4 lets a court dismiss a conviction after you complete probation, releasing you from most penalties attached to the offense. But the statute contains an explicit carve-out: in any later prosecution, the dismissed conviction “may be pleaded and proved and shall have the same effect as if probation had not been granted or the accusation or information dismissed.” The prosecutor can still use it as a strike. The statute also does not restore firearm rights.1California Legislative Information. California Penal Code PEN 1203.4
A 1203.4 dismissal can still help with employment and personal closure. It is simply the wrong tool if the strike itself is what you are trying to get rid of.
Romero Motion: Getting a Judge to Ignore the Strike
A Romero motion asks the sentencing judge to disregard a prior strike when calculating your sentence on a new felony. The name comes from the 1996 California Supreme Court decision in People v. Superior Court (Romero), which confirmed that trial courts can strike prior felony allegations under Penal Code 1385 “in furtherance of justice.”2Justia Law. People v. Superior Court (Romero) (1996)
A granted Romero motion does not erase the strike from your record. It just prevents the strike from doubling your sentence or triggering 25-to-life on the current charge. Because the motion is tied to sentencing, you cannot file one on its own; there has to be a pending felony case.
What the Judge Weighs
There is no automatic disqualifier. The judge decides whether you fall outside the “spirit” of the Three Strikes Law by looking at:
- The seriousness of the current offense
- The nature and age of the prior strike, and whether it was isolated or part of a pattern
- Your background, including employment, rehabilitation, family circumstances, and time without re-offending
Judges have wide discretion, and a judge who grants the motion must state reasons on the record.3California Legislative Information. California Penal Code PEN 1385 In practice, Romero motions succeed most often when the prior strike is old, the new offense is comparatively minor, and there is real evidence of rehabilitation. When the prior involved serious violence and so does the new charge, the odds shrink sharply.
Reducing a Wobbler Strike Under Penal Code 17(b)
This is the closest thing to permanently removing a strike. Penal Code 17(b) lets a court reclassify a “wobbler” from a felony to a misdemeanor.4California Legislative Information. California Penal Code PEN 17 A wobbler is an offense that could have been charged either way. Once the conviction is reduced to a misdemeanor, it no longer qualifies as a serious or violent felony and loses its status as a strike.
Not every strike offense is a wobbler. Murder, robbery, and rape are always felonies. Some qualifying offenses, such as assault with a deadly weapon, can be wobblers depending on the facts. The quickest way to check is the statute for your conviction: if county jail appears as a possible sentence alongside state prison, the offense is a wobbler.5California Courts. Record Cleaning – Felony Convictions and Proposition 47
You generally need to have completed probation on the original offense. A judge can reclassify the offense when granting probation, at any point during probation, or upon application afterward.4California Legislative Information. California Penal Code PEN 17 Unlike a Romero motion, no new criminal case is required.
Timing matters. A 17(b) request filed five years after probation ends, with a clean record in between, is a very different proposition from one filed the month after probation ends. If the motion is not urgent, building a stronger record of rehabilitation before filing can be the difference between a grant and a denial. If a 17(b) motion is denied, you can refile on a showing of changed circumstances such as additional law-abiding time, completion of new programs, or a change in the law.4California Legislative Information. California Penal Code PEN 17
Proposition 36 Resentencing for Third-Strike Life Sentences
Proposition 36, the Three Strikes Reform Act of 2012, applies to people already serving a 25-to-life third-strike term. Before the reform, that life sentence could be triggered even when the newest felony was nonviolent. Prop 36 limited the life term to cases where the current offense is itself a serious or violent felony.6Legislative Analyst’s Office. Proposition 36 – Three Strikes Law – Sentencing for Repeat Felony Offenders
People already serving life under the old rules can petition for resentencing under Penal Code 1170.126. To qualify, the current conviction cannot be a serious or violent felony, and you cannot have certain disqualifying priors involving sex offenses, firearm use, or specific drug charges.7California Legislative Information. California Penal Code PEN 1170.126 Even if you meet the technical requirements, the court can deny resentencing if it finds you would pose an unreasonable risk of danger to public safety. A grant means resentencing as a second-striker, typically a doubled sentence rather than life. Prop 36 does not apply to anyone serving a second-strike sentence.
Proposition 47 Reclassification
Proposition 47, passed in 2014, reclassified certain low-level felonies as misdemeanors. If your strike was one of those specific offenses, you can petition under Penal Code 1170.18 to have it reduced. Qualifying offenses include simple drug possession (not sales or trafficking), petty theft and shoplifting valued at $950 or less, forgery under $950, and receiving stolen property under $950.5California Courts. Record Cleaning – Felony Convictions and Proposition 47
Most strike convictions involve serious violence, so Prop 47 covers only a narrow slice. For the cases it does reach, the felony becomes a misdemeanor by operation of law and loses its strike status. You are ineligible if you have a prior requiring sex offender registration or a “super strike” conviction such as murder, attempted murder, or certain sex crimes.5California Courts. Record Cleaning – Felony Convictions and Proposition 47
What You’ll Need and How Filing Works
Whichever pathway you use, start with your official criminal history record. In California this is called a RAP sheet, maintained by the Department of Justice, and you can request your own copy using Form BCIA 8705.8State of California – Department of Justice – Office of the Attorney General. Criminal Records – Request Your Own The RAP sheet gives you the case numbers, dates, and statutory codes needed to pinpoint which convictions are strikes and which tool fits.
For a Romero motion or 17(b) reduction, evidence of rehabilitation is what moves judges. Useful documentation includes:
- Letters from employers, community leaders, or family
- Proof of steady employment or vocational training
- Certificates from educational or skills programs
- Records of counseling, substance abuse treatment, or anger management
For a Prop 36 petition, the court may also weigh disciplinary history and program participation while incarcerated.
File your motion in the superior court where the original conviction occurred (for a 17(b) reduction or Prop 36 petition) or where the new charge is pending (for a Romero motion). Serve a copy on the District Attorney. The court sets a hearing, both sides argue, and the judge rules. A granted Romero sets the strike aside for the current sentence only. A granted 17(b) reduction turns the felony into a misdemeanor and eliminates the strike. A granted Prop 36 petition resentences you as a second-striker.
Federal Consequences That May Survive
Even a successful state motion may leave certain federal disabilities in place. This matters most in three areas.
Firearms
Federal law prohibits anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition.9Office of the Law Revision Counsel. 18 U.S. Code 922 A Romero motion does not help, because the underlying conviction remains. A 17(b) reduction to a misdemeanor is stronger: once the offense is no longer punishable by more than a year, the federal bar generally no longer applies. A 1203.4 dismissal explicitly does not restore firearm rights.1California Legislative Information. California Penal Code PEN 1203.4
Immigration
For noncitizens, the immigration definition of “conviction” is federal and does not track state relief. Under USCIS policy, a conviction dismissed for rehabilitation reasons rather than because of a legal defect in the original proceedings is still a conviction for immigration purposes.10U.S. Citizenship and Immigration Services. Policy Manual Volume 12 – Part F – Chapter 2 – Adjudicative Factors Only a vacatur based on a constitutional or procedural defect eliminates the conviction for immigration purposes. A 17(b) reduction may help in some immigration contexts, but ICE has increasingly challenged whether state reclassifications carry federal weight. If you are not a citizen, talk to an immigration attorney before filing anything. The wrong kind of relief can draw attention without providing protection.
Federal Jury Service
A felony conviction disqualifies you from federal jury service unless your civil rights have been legally restored.11United States Courts. Juror Qualifications, Exemptions and Excuses A 17(b) reduction to a misdemeanor resolves this. A Romero motion does not, because the felony conviction stays on your record.
