What Is a Wobbler Offense in California? (Penal Code 17(b) Explained)

Posted by Sam Israels | Aug 18, 2026

In California criminal law, a wobbler offense is a crime that can be classified, charged, and punished as either a felony or a misdemeanor. The prosecutor initially classifies it based on the details of the crime and the defendant's criminal history, but a judge can later reduce it to a misdemeanor under California Penal Code 17(b).

In Los Angeles and throughout California, a "wobbler" gets its name because it wobbles between felony and misdemeanor status.

Because felony convictions carry life-altering consequences—including state prison time, loss of civil rights, and severe employment barriers—how a wobbler is handled can drastically alter the outcome of your case.

Wobbler offenses are common in cases involving theft, fraud, assault, domestic violence, and certain white-collar crimes.

Who Decides If a Wobbler Is a Felony or Misdemeanor?

A wobbler's classification can change at different stages of the legal process, decided primarily by prosecutors and judges.

1. Prosecutor Discretion (Pre-Filing & Filing Stage)

Initially, the prosecutor decides how to file the charge. In Los Angeles County:

  • Felony filings are evaluated and prosecuted by the District Attorney's Office.

  • Misdemeanor filings are typically handled by the City Attorney's Office.

Key factors prosecutors evaluate include:

  • Severity & Harm: The degree of injury or total financial loss.

  • Aggravating Factors: Use of a weapon or targeting a vulnerable victim.

  • Criminal History: Prior convictions or probation violations.

  • Cooperation: Whether the defendant cooperated with law enforcement.

2. Judicial Discretion (Penal Code 17(b))

Even if a prosecutor files the charge as a felony, a judge has independent authority under Penal Code 17(b) to reduce a felony wobbler to a misdemeanor.

Misdemeanor vs. Felony Penalties in California

Understanding the distinction between misdemeanor and felony penalties highlights why early legal defense is critical:

Penalty Category

Misdemeanor Wobbler

Felony Wobbler

Incarceration Up to 1 year in county jail State prison sentence (or county jail under PC 1170(h))
Probation Summary / Informal probation Formal probation (monitored by a probation officer)
Civil Rights Generally preserved Loss of firearm rights, voting restrictions (while serving sentence)
Long-Term Impact Minimal impact on housing/employment Severe restrictions on licensing, housing, and background checks
Immigration Lower risk of deportability High risk of deportability or inadmissible status

How to Reduce a Felony Wobbler to a Misdemeanor Under PC 17(b)

Under California Penal Code 17(b), a judge can reduce a felony wobbler to a misdemeanor at multiple stages of the criminal justice process:

  1. At the Preliminary Hearing: The defense can argue that the evidence or conduct warrants a misdemeanor reduction before the case proceeds to trial.

  2. At Sentencing: The judge can grant a misdemeanor sentence instead of a felony sentence.

  3. After Probation Completion: After successfully completing formal probation, the defense can petition the court for a post-conviction reduction to a misdemeanor.

Factors That Help Win a PC 17(b) Reduction:

  • A clean or minimal criminal record

  • A secondary or minor role in the alleged offense

  • Prompt payment of full restitution to the victim

  • Successful compliance with all probation terms

  • Strong evidence of personal rehabilitation, employment, or community involvement

Common Examples of California Wobbler Crimes

Many standard criminal charges under the California Penal Code and Vehicle Code are wobblers:

What Is a "Wobblette"?

A "wobblette" is an informal legal term for a minor offense that can "wobble" between:

  1. A misdemeanor, or

  2. An infraction (such as a minor traffic violation).

Unlike misdemeanors or felonies, infractions do not result in a criminal record or jail time and are typically punished only by monetary fines. Many low-level Vehicle Code and local municipal code violations are classified as wobblettes.

Can a Wobbler Conviction Be Expunged in California?

Yes. Once a felony wobbler is reduced to a misdemeanor under PC 17(b), it generally becomes eligible for expungement under Penal Code 1203.4.

Eligibility criteria for expungement include:

  • Successful completion of probation (or early termination granted).

  • No current criminal charges or active state prison sentences.

  • Full payment of all court fines, fees, and restitution.

Note: Certain convictions, particularly specific sex offenses involving minors, are excluded from expungement eligibility under California law.

Frequently Asked Questions (FAQ)

Will I know immediately if my charge is a felony or misdemeanor?

No. Official classification is not finalized until the prosecution formally files charging documents with the court at or before your initial arraignment.

Can a prosecutor change a wobbler charge after filing?

Yes. Prosecutors can amend or upgrade/downgrade charges during plea negotiations, after a preliminary hearing, or as new evidence comes to light.

Does having no prior criminal record guarantee a misdemeanor filing?

While not guaranteed, having a clean record is one of the single most effective mitigating factors in convincing a prosecutor or judge to treat a wobbler as a misdemeanor.

Is it possible to prevent a felony charge before court?

Yes. An attorney can perform pre-filing intervention (contacting the District Attorney or City Attorney before charges are formally filed) to present mitigating evidence and urge them to file misdemeanor charges or reject the case entirely.

Why Early Legal Defense Is Critical for Wobbler Cases

Because prosecutor and judicial discretion govern wobbler offenses, early intervention by a defense attorney can dramatically alter the trajectory of your case. Strategic defense advocacy in the early stages can influence:

  • Pre-filing charging decisions (Felony vs. Misdemeanor)

  • Bail amounts and release conditions

  • Plea negotiation terms

  • Post-probation record expungement and reduction
