Charged with a crime in San Diego? Wondering how the case will affect your reputation, career, and freedom? Trying to figure out what comes next? Look no further! David’s book addresses common misconceptions and mistakes made by those charged with a crime in San Diego. Some of the chapters include topics such as:
Assault by force likely to produce great bodily injury is a strike offense that can send you to state prison. Our San Diego defense lawyers fight these charges. Call 24/7.
A charge under Penal Code Section 245(a)(4) changes everything overnight. One moment, life is normal. The next, you’re staring down a felony, a potential strike on your record, and years in state prison.
The circumstances that lead to these charges are rarely black and white. A bar argument that turned physical. A confrontation where you defended yourself and the other person called the police first. A situation where someone got hurt, but the story being told to prosecutors isn’t what actually happened. A misidentification in a chaotic group altercation where blame landed on the wrong person.
Charges are accusations, not convictions. The prosecution still has to prove every element beyond a reasonable doubt, and that’s a high bar.
The fear, the uncertainty about your job, your family, your freedom: it’s all understandable, as is to be expected. But what matters now is the defense you build. That starts with hiring the best, locally experienced criminal defense lawyers possible.
At David P. Shapiro Criminal Defense Attorneys, we’ve defended clients charged with assault causing great bodily injury throughout San Diego County, from Central Courthouse downtown to El Cajon, Chula Vista, and Vista. As experienced San Diego violent crimes defense lawyers, we know how the San Diego District Attorney’s office prosecutes these cases, we know the courtrooms, and we know how to fight back.
The prosecution is already building their case. Evidence fades. Witnesses forget. The window for the strongest defense is now.

What Is Assault by Force Likely to Produce Great Bodily Injury?
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 Now, let’s break down what that actually means, because this charge is widely misunderstood.
First, the critical distinction: this is an assault charge, not a battery charge. What does that mean? Well, it means the prosecution does not have to prove that anyone was actually injured. They don’t even have to prove you made physical contact with anyone. The charge is about the type of force you used, not the result.
“Great bodily injury” means significant or substantial physical injury, something greater than minor or moderate harm.2 Think broken bones, concussions, injuries requiring surgery or hospitalization. A bruise or a scrape typically does not qualify.
“Force likely to produce” is the key phrase. The question isn’t whether great bodily injury actually happened. The question is whether the force you used was the kind of force that could produce that level of injury. Stomping on someone, repeatedly punching someone on the ground, choking, throwing someone headfirst into concrete: these are the types of acts prosecutors point to. A single open-hand slap or a shove, on the other hand, typically does not rise to this level.
Why does this matter for your defense? Because if the force you used was not the type likely to produce great bodily injury, you cannot be convicted under PC 245(a)(4), even if the other person did get hurt. Every element creates a potential avenue for defense.
How PC 245(a)(4) Differs from Assault with a Deadly Weapon
This is a question we hear often. What’s the difference between 245(a)(1) and 245(a)(4)? Well, they’re different subdivisions of the same statute. Section 245(a)(1) applies when a deadly weapon is involved: a knife, a bat, a bottle, a vehicle. Section 245(a)(4) applies when no weapon is involved but the force used, typically hands, fists, feet, or body weight, was likely to produce great bodily injury.3
The penalties are identical. The distinction matters for how the case is charged and how the defense is built. If a weapon was allegedly involved, the charge would instead fall under assault with a deadly weapon (PC 245(a)(1)).
What Must the Prosecution Prove?
Here’s what the prosecution is up against. To convict you of assault by force likely to produce great bodily injury under PC 245(a)(4), they must prove ALL of the following elements beyond a reasonable doubt:4
1. You committed an act that by its nature would directly and probably result in the application of force to a person.
This means you did something, some physical act, that was naturally and probably going to result in force being applied to another person. It doesn’t have to be a punch. It could be swinging, lunging, or any physical act directed at someone.
2. You acted willfully.
“Willfully” means you did the act on purpose. It does not mean you intended to hurt someone or break the law. You just had to intend to do the physical act itself. An accidental collision doesn’t qualify. A reflexive movement doesn’t qualify.
3. You were aware of facts that would lead a reasonable person to realize the act would directly and probably result in force being applied to someone.
This is the awareness element. You knew, or should have known, that what you were doing would probably result in physical force being applied to another person.
4. You had the present ability to apply force.
You were physically positioned and capable of carrying out the act. If you were restrained, too far away, or physically incapable, this element fails.
5. The force you used was likely to produce great bodily injury.
This is the element that elevates the charge from simple assault to a felony strike offense. The prosecution must prove the force was of a type and degree likely to cause significant or substantial injury.
6. You did not act in self-defense or defense of another person.
If you were defending yourself or someone else, the prosecution bears the burden of disproving that claim beyond a reasonable doubt.
Every element is a question mark for the prosecution and an opportunity for the defense. Miss one element, and the charge fails.
Wobbler Status: Why It Matters More Than You Think
PC 245(a)(4) is classified as a wobbler under California law, meaning the prosecution can file it as either a felony or a misdemeanor.5 This distinction is not just about the difference in jail time. It’s about whether you walk away with a strike on your record.
Felony vs. Misdemeanor: The Real Difference
| Factor | Felony Conviction | Misdemeanor Conviction |
|---|---|---|
| Incarceration | 2, 3, or 4 years state prison | Up to 1 year county jail |
| Strike on Record | Yes | No |
| Future Felony Impact | Sentence presumptively doubled | None |
| Firearm Rights | Lifetime ban | 10-year ban |
| Professional License | Severe impact | Case-by-case |
| Expungement | Extremely difficult with strike | Available under PC 1203.4 |
See that difference? A misdemeanor conviction means county jail, no strike, and a realistic path to clearing your record down the road. A felony conviction means state prison, a strike that follows you for life, and a doubled sentence on any future felony.
This is why wobbler reduction under Penal Code Section 17(b) is one of the most important strategic objectives in these cases.6 Factors that favor reduction include no prior criminal history, minimal injury to the alleged victim, provocation, strong community ties, and the overall circumstances of the offense. We pursue this aggressively when the facts support it.
Strike Implications
A strike changes everything, not just for this case, but for the rest of your life. Here’s what a strike actually means in practice.
A felony conviction under PC 245(a)(4) is classified as a serious felony under Penal Code Section 1192.7(c)(8).7 That means it counts as a strike under California’s Three Strikes Law.
The practical consequences:
- Second strike: Any future felony conviction results in a sentence that is presumptively doubled.8
- Third strike: A third felony with two prior strikes can result in 25 years to life in state prison.9
- Custody credits: Limited, if any, custody credits apply to strike sentences. There is no early release the way there is with many other offenses.
- Lasting record: Strike convictions are extremely difficult to remove from your record.
Here’s the critical point: a misdemeanor conviction under PC 245(a)(4) is NOT a strike. This is why the wobbler distinction matters so much. Reducing the charge from a felony to a misdemeanor doesn’t just reduce your sentence. It eliminates the strike entirely. For many of our clients, that is the single most important objective in the case.
Penalties and Consequences
Prison and Jail Sentences
| Charge | Sentence | Fine |
|---|---|---|
| Misdemeanor PC 245(a)(4) | Up to 1 year county jail | Up to $1,000 |
| Felony PC 245(a)(4) | 2, 3, or 4 years state prison | Up to $10,000 |
| With GBI Enhancement (PC 12022.7(a)) | Additional 3 years consecutive | — |
| GBI, victim in coma/paralysis (PC 12022.7(b)) | Additional 5 years consecutive | — |
| GBI, victim 70+ years old (PC 12022.7(c)) | Additional 5 years consecutive | — |
| GBI, victim under 5 (PC 12022.7(d)) | Additional 4-6 years consecutive | — |
The GBI Enhancement: Base Charge vs. Actual Injury
This is something a lot of people, and even some lawyers, get confused about. The base charge under PC 245(a)(4) is about the type of force you used. Did you use force that was likely to produce great bodily injury? That’s the question. No actual injury is required.
The GBI enhancement under Penal Code Section 12022.7 is a separate allegation.10 It requires proof that the victim actually suffered great bodily injury. When both are charged together, you’re facing the base sentence plus an additional 3 to 6 years served consecutively. So you can see how these things snowball into very serious prison time.
Sentencing Under SB 567
California Senate Bill 567, effective January 1, 2022, changed how judges select from the sentencing triad (2, 3, or 4 years). Previously, the middle term of 3 years was the presumptive sentence. Now, the court must impose the lower term of 2 years if certain mitigating circumstances exist, including the defendant’s youth at the time of the offense, trauma history, or if the crime was connected to prior victimization.11 This is a significant development that can benefit first-time offenders and defendants with documented mitigating factors.
Collateral Consequences
Beyond prison time and fines, a conviction under PC 245(a)(4) carries consequences that follow you long after your sentence is served.
Immigration consequences. A felony conviction for assault by force likely to produce GBI can be classified as an aggravated felony or a crime involving moral turpitude under federal immigration law. For non-citizens, this can trigger deportation proceedings, denial of naturalization, or inadmissibility. If you are not a U.S. citizen, the immigration consequences of this charge may be more severe than the criminal penalties.
Professional licenses. The State Bar, medical boards, nursing boards, real estate commissions, and teaching credential agencies all conduct background checks and can deny, suspend, or revoke licenses based on a felony conviction for a violent offense. A misdemeanor conviction may have a less severe impact, depending on the licensing body.
Firearm rights. A felony conviction results in a lifetime ban on owning or possessing firearms under both California and federal law.12 Even a misdemeanor conviction under PC 245(a)(4) triggers a 10-year firearm prohibition under Penal Code Section 29805.
Employment and housing. Felony convictions, particularly for violent offenses, create significant barriers to employment and housing. Many employers and landlords conduct background checks, and a strike offense raises immediate red flags.
Child custody. In family court proceedings, a conviction for a violent felony can be used as evidence against you in custody determinations. Courts prioritize the safety of children, and a PC 245(a)(4) conviction can shift the balance.
Voting rights. Felony convictions result in the loss of voting rights while incarcerated. Rights are restored upon completion of the sentence, including parole and probation.
Defense Strategies for PC 245(a)(4) Charges
These cases are defensible. The question is identifying the right defense strategy based on the specific facts of your case and then executing that strategy with preparation, professionalism, and precision.
Many lawyers, based on inexperience, indifference, and/or outright incompetence, will push for a quick plea without investigating the case. The reality of the situation is that these cases require thorough analysis before you know what your best options are.
Let’s walk through the approaches we consider when building a defense:
Self-Defense or Defense of Others
This is often the strongest defense in PC 245(a)(4) cases, particularly in situations involving mutual combat, bar fights, or confrontations where both parties were physical.13
California law recognizes your right to defend yourself or another person from imminent harm. If you reasonably believed you or someone else faced immediate danger of bodily injury, and you used only the force reasonably necessary to defend against that danger, your actions were lawful.
The prosecution bears the burden of disproving self-defense beyond a reasonable doubt. We can, and will, investigate and present evidence supporting self-defense if the facts support a position to do so. That includes witness statements, surveillance footage, injuries to you, and the sequence of events leading up to the altercation.
The Force Was Not Likely to Produce Great Bodily Injury
What counts as force “likely to produce great bodily injury”? This is a fact-intensive question, and it’s where many of these cases are won or lost.
A single punch during an argument is not the same as stomping on someone’s head while they’re on the ground. A push that causes someone to stumble is not the same as throwing someone into a concrete wall. The prosecution must prove the force you used was the type likely to cause significant or substantial injury, not just any injury.
If the force doesn’t meet that threshold, the charge should be reduced to simple assault under PC 240 or simple battery under PC 242, both misdemeanors, neither a strike.14 15 Expert testimony on biomechanics and injury potential can support this argument.
False Accusation and Misidentification
People get wrongfully accused of assault all the time, especially in chaotic situations. Bar fights with multiple participants. Street confrontations where bystanders become witnesses to events they only partially saw. Domestic disputes where the first person to call 911 gets treated as the victim.
We scrutinize every piece of identification evidence: surveillance footage, witness statements, inconsistencies in the alleged victim’s account, and any motive the accuser may have to lie. In some cases, the strongest defense is proving you simply weren’t the person who did what the prosecution claims.
Lack of Willfulness: Accident
If the act was not willful, the charge fails. An accidental collision, a reflexive movement, or an unintentional act during a physical activity does not satisfy the willfulness element. “Willfully” means you intended to do the act itself. If you didn’t, that’s a complete defense.
Insufficient Evidence
The prosecution bears the burden of proving every element beyond a reasonable doubt. That’s the highest standard in our legal system. We challenge weak forensic evidence, unreliable witnesses, gaps in the prosecution’s timeline, and the absence of medical records or physical evidence corroborating the alleged level of force.
When the evidence doesn’t hold up under scrutiny, the case becomes much more manageable.
Constitutional Violations
Evidence obtained in violation of your constitutional rights may be suppressed, meaning the jury never sees it. We examine whether police conducted an illegal search or seizure, whether your Miranda rights were violated during questioning, and whether due process was followed at every stage.
Suppressing key evidence can fundamentally change the strength of the prosecution’s case.
Wobbler Reduction and Charge Bargaining
Even when the evidence is strong, the defense doesn’t end there. We can, and will, pursue wobbler reduction under PC 17(b) to bring the charge down to a misdemeanor if the facts support a position to do so.16 We also negotiate with prosecutors to reduce charges to lesser offenses like simple assault (PC 240), simple battery (PC 242), or disturbing the peace (PC 415) when appropriate.17
The goal is always the best possible outcome under the facts and circumstances of your case. Sometimes that’s a dismissal. Sometimes it’s a reduction that keeps a strike off your record. We evaluate every option.
The Preliminary Hearing as a Strategic Tool
In felony cases, the preliminary hearing is more than a procedural step. It’s a strategic opportunity. We can challenge the prosecution’s evidence, cross-examine witnesses, and argue that the force used did not rise to the level required under PC 245(a)(4). If successful, the judge can reduce or dismiss the charges before the case ever reaches a jury.
The preliminary hearing also locks in witness testimony under oath, which can be invaluable if the case proceeds to trial and witnesses change their stories.
Related Charges: Understanding the Differences
PC 245(a)(4) doesn’t exist in a vacuum. Understanding how it relates to other charges helps you see the full picture of what you’re facing, and where the defense opportunities lie.
| Offense | Code Section | Classification | Key Difference from PC 245(a)(4) |
|---|---|---|---|
| Simple Assault | PC 240 | Misdemeanor | No force likely to produce GBI; no strike |
| Simple Battery | PC 242 | Misdemeanor | Requires actual contact; no GBI-level force |
| Assault with Deadly Weapon | PC 245(a)(1) | Wobbler / Strike | Weapon involved; same penalties |
| Battery Causing Serious Bodily Injury | PC 243(d) | Wobbler | Requires actual contact AND actual serious injury |
| Criminal Threats | PC 422 | Wobbler / Strike | Verbal threats of GBI; often charged alongside assault |
| Mayhem | PC 203 | Felony / Strike | Disfigurement or loss of body part |
| Corporal Injury to Spouse | PC 273.5 | Wobbler | DV context; requires traumatic condition to intimate partner |
| Disturbing the Peace | PC 415 | Misdemeanor / Infraction | Common plea bargain reduction |
The bottom line: the specific charge matters enormously. The difference between PC 245(a)(4) as a felony and a reduction to PC 415 disturbing the peace is the difference between state prison with a strike and an infraction. That’s why the defense strategy, and the attorney executing it, matters so much.
