Assault by Force Likely to Produce Great Bodily Injury Defense Lawyers (PC 245(a)(4))

Assault causing great bodily injury under PC 245(a)(4) is a felony. Prison time possible. Our lawyers can help. Call 24/7.

Sometimes a fight escalates. And suddenly you’re facing felony charges.

Penal Code 245(a)(4) covers assault “by any means of force likely to produce great bodily injury”—even when no weapon is involved. This is the charge prosecutors use when someone gets hurt in a fight, when a punch causes a broken bone, or when any physical altercation results in injuries that look serious on paper.

The circumstances are rarely black and white. Bar fights where both parties were swinging. Altercations that started with someone else pushing first. Self-defense situations where the other person ended up hurt. Most people facing PC 245(a)(4) charges never intended to cause serious injury—they were caught in a moment that got out of control.

Here’s something important that many people don’t know: PC 245(a)(4) is NOT a strike offense. Unlike assault with a deadly weapon under PC 245(a)(1) or assault with a firearm under PC 245(a)(2), this section of the assault statute does not trigger California’s Three Strikes Law when charged alone.

This distinction matters. It affects how prosecutors evaluate the case, how plea negotiations proceed, and what your life looks like after this is over.

Charges are accusations, not convictions. Every element still has to be proven beyond a reasonable doubt. We’ve defended clients against PC 245(a)(4) charges throughout San Diego County, and we know how to fight them.

Quick Reference — PC 245(a)(4) Assault by Force Likely to Produce GBI

What Is Assault by Force Likely to Produce GBI?

Penal Code Section 245(a)(4) makes it a crime to commit an assault “by any means of force likely to produce great bodily injury.”¹

This charge fills the gap between simple assault and assault with a deadly weapon. It applies when:

• No weapon was used, AND
• The force used was severe enough that it could have caused significant injury

You don’t need to actually cause great bodily injury to be charged under this section. The statute focuses on the likelihood that your actions could have caused serious harm—not whether they actually did.

“Great Bodily Injury” Defined:

Under California law, “great bodily injury” means significant or substantial physical injury—more than minor or moderate harm. Examples include:

• Broken bones
• Wounds requiring stitches
• Concussions
• Loss of consciousness
• Injuries requiring prolonged medical treatment

Elements of Assault by Force Likely to Produce GBI

To convict you of this offense, the prosecutor must prove ALL of the following beyond a reasonable doubt:²

1. You did an act that by its nature would directly and probably result in the application of force to a person.

“Force” means harmful or offensive touching. Under this statute, the force must be of a type likely to cause significant injury.

2. The force used was likely to produce great bodily injury.

This is the key element that distinguishes PC 245(a)(4) from simple assault. The prosecution must prove that the force you allegedly used was severe enough to likely cause serious injury—not just minor harm.

3. You did that act willfully.

You intended to do the act, even if you didn’t intend to cause injury.

4. When you acted, you were aware of facts that would lead a reasonable person to realize that your act by its nature would directly and probably result in the application of force to someone.

You understood your actions could result in force being applied.

5. When you acted, you had the present ability to apply force likely to produce great bodily injury.

You were physically capable of causing the level of harm alleged.

The burden is on the prosecution to prove all of this. Beyond a reasonable doubt. That’s a high bar.

Critical Distinction: This Is NOT a Strike

Here’s what makes PC 245(a)(4) different from other assault charges:

This is the only subsection of PC 245(a) that is not a strike offense.³

Why this matters:

• A felony conviction under PC 245(a)(4) does NOT double future sentences
• It does NOT count toward Three Strikes
• It does NOT require serving 85% of the sentence
• It offers better plea negotiation positions than strike-eligible charges

This doesn’t mean the charge isn’t serious—it carries up to 4 years in state prison as a felony. But the absence of strike status significantly changes the long-term landscape of your case.

Wobbler Status: Misdemeanor vs. Felony

PC 245(a)(4) is a “wobbler”—the prosecution can file it as either a misdemeanor or a felony. Factors that influence this decision include:

Factors favoring misdemeanor filing:

• No actual injury occurred
• Minor injury that healed quickly
• No prior criminal history
• Mutual combat where both parties participated
• Mitigating circumstances (provocation, self-defense elements that weren’t complete defenses)

Factors favoring felony filing:

• Significant injuries resulted
• Prior criminal history, especially violent offenses
• Vulnerable victim (elderly, disabled, child)
• Aggravating circumstances
• Repeated blows or sustained attack

Even if the prosecution files as a felony, we can sometimes negotiate reduction to a misdemeanor as part of a resolution—or seek reduction to a misdemeanor under PC 17(b) after successful completion of probation.

Defense Strategies for PC 245(a)(4)

These charges often arise from chaotic situations with conflicting accounts. Effective defenses include:

Self-Defense

California law recognizes your right to defend yourself with reasonable force when you reasonably believe you’re facing imminent bodily harm. If you were attacked first—or reasonably believed you were about to be—and used only the force necessary to protect yourself, you have a complete defense. The fact that the other person got hurt doesn’t automatically mean you’re guilty.

Defense of Others

The same principles apply when you’re protecting someone else from harm. Parents protecting children, friends protecting friends, bystanders intervening in attacks—these situations can give rise to valid defenses.

Mutual Combat

When both parties willingly engaged in a fight, this can affect both the charges and the defenses available. While mutual combat doesn’t provide a complete defense, it changes the analysis of who was the aggressor and whether your actions were reasonable.

Force Not Likely to Cause GBI

Not every fight involves force “likely to produce great bodily injury.” If the force used was ordinary pushing, shoving, or minor physical contact, the prosecution may not be able to prove this element. A single push or slap—while potentially constituting simple assault or battery—may not rise to the level required for PC 245(a)(4).

No Willful Act

Accidents aren’t crimes. If the force was unintentional—you lost your balance and fell into someone, your arm swung while you were stumbling—there’s no willful act.

Insufficient Evidence

Many of these cases rely heavily on witness testimony, and witnesses often have different accounts of what happened. Physical evidence may not support the prosecution’s theory. Medical records may show injuries inconsistent with the alleged assault. We examine every piece of evidence to identify weaknesses in the prosecution’s case.

Consequences of a Conviction

Even without strike status, a conviction for PC 245(a)(4) carries significant consequences:

Direct Penalties

Misdemeanor: Up to 1 year county jail, fine up to $1,000, probation

Felony: 2, 3, or 4 years state prison, fine up to $10,000, formal probation possible

Collateral Consequences

Firearm Rights: A felony conviction triggers a lifetime firearm prohibition. A misdemeanor conviction may trigger a 10-year prohibition.

Immigration: This offense may qualify as a crime involving moral turpitude (CIMT) or, depending on the circumstances, an aggravated felony under federal immigration law—triggering deportation proceedings for non-citizens.

Professional Licenses: A conviction for violent conduct can result in discipline or denial of professional licenses in healthcare, education, law, real estate, and other regulated professions.

Employment: Background checks will reveal the conviction. Many employers have policies against hiring applicants with violent offense convictions.

Housing: Some landlords and housing programs exclude applicants with violent felony convictions.

Related Charges

Understanding how this charge relates to other offenses helps you understand what you’re facing:

Important distinction from PC 245(a)(1):

PC 245(a)(1) covers assault with a deadly weapon OR “by any means of force likely to produce great bodily injury.” PC 245(a)(4) also covers force likely to produce GBI. The difference is subtle but significant:

• PC 245(a)(1) is a strike
• PC 245(a)(4) is NOT a strike

How prosecutors charge matters enormously. If you’re facing PC 245(a)(1) charges for conduct that might fit under PC 245(a)(4), negotiating to the non-strike section can be a critical victory.
