Defending California Three Strikes Cases: Proposition 36 Reforms & Strike Challenging Tactics

Legal Review: Los Angeles Criminal Defense Legal Editorial Board

California's 'Three Strikes and You're Out' law—codified in California Penal Code §§ 667(b)–(i) and § 1170.12—represents one of the most punitive repeat-offender sentencing frameworks in American jurisprudence. Originally enacted by the California Legislature and voter initiative in 1994, the law mandated a draconian sentence of 25 years to life for any third felony conviction, regardless of how minor the third offense might be. The passage of Proposition 36 (The Three Strikes Reform Act of 2012) instituted vital structural reforms, requiring the third strike itself to be an enumerated serious or violent felony to trigger a mandatory life sentence. Defending against strike enhancements in Los Angeles County requires an exacting audit of prior convictions, challenging foreign and juvenile strike qualifications, and litigating discretionary strike dismissals under People v. Superior Court (Romero).

The Statutory Architecture: Second Strikes vs. Third Strikes

Under the California Penal Code, a prior conviction qualifies as a 'Strike' if it is classified as a **serious felony** under California Penal Code § 1192.7(c) or a **violent felony** under California Penal Code § 667.5(c). The Three Strikes sentencing escalator operates across two distinct carceral tiers:

  • The Second Strike Escalator: If a defendant has one prior serious or violent felony conviction and is subsequently convicted of any new felony offense (even a non-serious, non-violent felony like commercial burglary or driving a stolen vehicle), the statutory sentence for the new offense is automatically doubled. Furthermore, under California Penal Code § 2933.1, conduct credits for second-strike offenders are severely restricted, requiring the individual to serve at least 80% of their sentence before becoming eligible for parole consideration.
  • The Third Strike Escalator: Prior to 2012, a defendant with two prior strikes who committed any third felony faced a mandatory sentence of 25 years to life in California State Prison. Under current law following Proposition 36, a 25-years-to-life indeterminate sentence can only be imposed if the current third-strike offense is itself classified as a serious or violent felony, or if a statutory disqualifier applies.

Proposition 36 Reforms: Limiting 25-to-Life Exposure

Enacted by California voters in November 2012, Proposition 36 (codified in California Penal Code §§ 667(e)(2)(C) and 1170.12(c)(2)(C)) fundamentally changed the Three Strikes framework by establishing that an individual with two prior strikes who commits a new felony is not subject to a 25-to-life sentence unless the new offense is serious or violent.

However, Proposition 36 preserved statutory exceptions where a non-serious, non-violent third strike can still result in a mandatory 25-years-to-life term:

  • The 'Super Strike' Exclusion: If the defendant has a prior conviction for any offense listed in California Penal Code § 667(e)(2)(C)(iv)—such as murder, attempted murder, gross vehicular manslaughter while intoxicated, or sexually violent offenses—the defendant is permanently disqualified from Proposition 36 protections and must receive 25 to life for any third felony conviction.
  • Firearms and Deadly Weapons: If during the commission of the current third-strike offense, the defendant was armed with a firearm or deadly weapon, or intended to cause great bodily injury.
  • Enumerated Drug Trafficking: If the current offense involves large-scale manufacturing or distribution of controlled substances under Health & Safety Code § 11370.4.

Romero Motions: Dismissing Prior Strikes Under Penal Code § 1385

Even when a prior conviction qualifies as a lawful strike, defense counsel can petition the court to dismiss the strike for sentencing purposes by filing a Romero Motion.

In People v. Superior Court (Romero) (1996), the California Supreme Court ruled that trial judges retain inherent discretionary authority under California Penal Code § 1385(a) to dismiss or strike prior serious or violent felony allegations 'in furtherance of justice.' In People v. Williams (1998), the Supreme Court established the definitive legal test for evaluating a Romero motion: the court must consider whether, in light of the nature and circumstances of their present felonies and prior serious and/or violent felony convictions, and the particulars of their background, character, and prospects, the defendant may be deemed outside the scheme's spirit, in whole or in part, and hence should be treated as though they had not previously been convicted of one or more strikes.

To successfully litigate a Romero motion in Los Angeles Superior Court, defense counsel compiles a comprehensive mitigation brief demonstrating:

  1. The Remoteness of Prior Strikes ('Washout Period'): If 10, 15, or 20 years elapsed between the prior strike and the current allegation, during which the client maintained law-abiding employment and family stability, the passage of time weighs heavily in favor of dismissal.
  2. The Non-Violent Character of the Current Offense: Demonstrating that the current offense involved no physical violence, weapons, or injuries.
  3. Personal Character and Prospects: Documenting steady employment, military service, community involvement, enrollment in substance abuse rehabilitation, and strong familial responsibilities.

If the presiding judge grants the Romero motion, the strike is dismissed for sentencing, eliminating the mandatory 25-to-life sentence and permitting the court to impose a standard determinate sentence or grant local felony probation.
