California Penal Code § 243 d PC defines the crime of “battery causing serious bodily injury.” Depending on the case, it can be a misdemeanor carrying up to one year in jail or a felony carrying up to four years in jail.
The language of the code section reads as follows:
PC 243. (d) When a battery is committed against any person and serious bodily injury is inflicted on the person, the battery is punishable by imprisonment in a county jail not exceeding one year or imprisonment pursuant to subdivision (h) of Section 1170 for two, three, or four years.
The term “serious bodily injury” means any serious impairment of someone’s physical condition. Medical treatment is not necessarily required for a victim’s injuries to be “serious.”
California courts have found the following injuries to be “serious bodily injury:”
- a lost tooth up to its root,
- a loss of consciousness,
- a cut under the eye requiring eight stitches,
- a broken tooth, wounds on eyebrow, and lips requiring sutures, and
- bone fractures, broken bones, or serious disfigurement.

Our California criminal defense attorneys address the following in this article:
1. What is aggravated battery?
To convict you of aggravated battery in California, prosecutors must prove beyond a reasonable doubt the following three elements of Criminal Jury Instruction “CALCRIM” 925:
- you willfully and unlawfully touched the alleged victim in a harmful or offensive manner,
- the alleged victim suffered serious bodily injury as a result of the force or touching, and
- you did not act in lawful self-defense or defense of others.1
Under California criminal law, you commit an act “willfully” when you do it willingly or on purpose.2
A “touching” occurs when you make physical contact with another party, including through clothing.3
Example: Overcome with anger, Melissa shoves Ben lightly. This causes Ben to slip and fall, breaking his ankle.
Melissa did not touch Ben forcefully—but because she touched him at all, and a serious injury resulted, she may be guilty of battery causing serious injury.
Note that offensive touching can be done indirectly by causing an object or someone else to touch the alleged victim.4
2. Defenses
Here at Shouse Law Group, we have represented literally thousands of people charged with violent offenses, including aggravated battery causing serious bodily injury. In our experience, the following three defenses have proven very effective with prosecutors, judges, and juries.
You Acted in Self-Defense
Self-defense works as a legal defense against a battery charge when all of the following are true:
- you reasonably believed that you (or another person) were in imminent danger of suffering bodily harm,
- you reasonably believed that the immediate use of force was necessary to defend against that danger, and
- you used no more force than was reasonably necessary to defend against that danger.5
To prove this defense, we amass such evidence as video surveillance footage and eyewitness accounts to show that your actions were justifiable under the circumstances.
There Were No Serious Injuries
PC 243d charges apply only if you commit a battery and cause the victim to suffer a serious injury. A defense, then, is for you to say that while you may have committed a battery, the alleged victim did not suffer a serious injury.
To prove this defense, we rely on medical expert testimony to show that any injury the alleged victim sustained does not meet the definition of “serious.”
It Was an Accident
You cannot be convicted of aggravated battery causing serious bodily injury if you did not touch the victim willfully—that is, if the entire incident was an accident.
So if you accidentally shoved someone in a crowd, or tripped and fell into them, you should not be found guilty of this crime.6
To show that what happened was an accident, we would consult with an “accident reconstruction expert.” This expert may be able to show that what transpired could not possibly have been intentional.
3. Sentencing
A violation of PC 243d is a wobbler, meaning that a prosecutor can charge as either a misdemeanor or a felony depending on:
- the facts of the case, and
- your criminal history.
Misdemeanor aggravated battery causing serious bodily injury is punishable by:
- custody in county jail (as opposed to state prison) for up to one year, and/or
- a maximum fine of $1,000.7
Felony aggravated battery causing serious bodily injury is punishable by:
- jail time of up to four years, and/or
- a fine of up to $10,000.8
Note that your sentence will increase by three to six years if the victim’s injuries qualify as “great bodily injuries” per PC 12022.7.9
