California PC 243.4(a) Sexual Battery: Penalties and Defenses

California Penal Code section 243.4(a) is the state’s felony-eligible sexual battery law. It applies when someone touches an intimate part of another person, for a sexual purpose, while that person is unlawfully restrained. Prosecutors can file it as either a misdemeanor carrying up to a year in county jail or a felony punishable by two, three, or four years in state prison, and any conviction brings sex offender registration and firearm restrictions with it.¹

What the Prosecution Has to Prove

A conviction under 243.4(a) requires the state to prove four things beyond a reasonable doubt:

The defendant touched an intimate part of another person.
The person was unlawfully restrained at the time.
The touching was against that person’s will.
The touching was done for sexual arousal, sexual gratification, or sexual abuse.¹

“Intimate part” is defined in the statute as the sexual organ, anus, groin, or buttocks of any person, or the breast of a female. The sexual intent element is broader than it sounds. The defendant doesn’t have to be seeking personal pleasure; touching done to humiliate, hurt, or intimidate the victim also meets the “sexual abuse” prong.

Subsection (a) has a specific definition of “touches” that often decides cases. Under subdivision (f), which governs (a), the contact must be with the skin of the other person, whether directly or through the clothing of the person doing the touching. A defendant wearing a glove who touches the victim’s bare skin still qualifies. Touching the victim over their clothing does not. That same conduct can still be charged as misdemeanor sexual battery under subsection (e), which uses a broader definition of touching.

The Restraint Element Is Where These Cases Turn

Unlawful restraint is the fact that separates felony-eligible 243.4(a) from the lower-level misdemeanor under 243.4(e). The prosecution has to show the defendant controlled the victim’s freedom of movement and did so against the victim’s will. Handcuffs or ropes aren’t necessary. Pinning someone against a wall, blocking a door, or using physical force to keep someone from leaving can all qualify. California’s false imprisonment statute, which defines the unlawful violation of another person’s personal liberty, informs how courts analyze this element.²

The restraint has to be more than the physical force used to accomplish the touch itself. A quick grab, without anything more holding the person in place, is not restraint for purposes of (a). The prosecution needs a separate layer of control over the victim’s movement. That line is often where felony exposure survives or collapses.

Penalties if Convicted

243.4(a) is a wobbler, meaning the prosecutor chooses between misdemeanor and felony filing. That decision usually depends on the facts of the incident, the severity of the restraint, and the defendant’s record.

Misdemeanor: up to one year in county jail and a fine of up to $2,000.¹
Felony: two, three, or four years in state prison and a fine of up to $10,000.¹

The court can grant probation under either filing. Typical conditions include counseling, community service, stay-away orders, and regular reporting to a probation officer. Violating probation terms can result in revocation and imposition of the original jail or prison sentence.

Sex Offender Registration

Any conviction under Penal Code 243.4, misdemeanor or felony, triggers registration under Penal Code 290. Registration means providing your home address, employment information, and other personal details to local law enforcement, and updating that information within five working days of any move to a new city, county, or campus. Failing to register or update is a separate crime that can add jail or prison time on top of the underlying case.³

Since 2021, California has used a tiered registration system. A felony conviction under 243.4(a) is a Tier 3 offense, which requires lifetime registration. A misdemeanor conviction under 243.4 falls into a lower tier with a shorter minimum period, after which a petition under Penal Code 290.5 can seek to end the obligation. Tier 1 requires at least 10 years of registration; Tier 2 requires at least 20.⁴ That gap between lifetime registration and a 10-year obligation is one of the most consequential differences between a felony and a misdemeanor outcome.

Firearm Restrictions

Any 243.4 conviction cuts off firearm rights, but for different lengths of time. A misdemeanor conviction brings a 10-year prohibition on owning or possessing firearms under Penal Code 29805, which specifically lists section 243.4.⁵ A felony conviction brings a lifetime ban under both California and federal law.⁶

How 243.4(a) Differs from Misdemeanor Sexual Battery Under (e)

If you’re trying to understand why one case is a felony and another isn’t, the answer is almost always the restraint element and the touching definition. Subsection (e) covers unwanted sexual touching without unlawful restraint and without the other aggravating circumstances the statute lists. It is a misdemeanor only, carrying up to six months in county jail and a fine of up to $2,000, or up to $3,000 if the defendant was the victim’s employer.¹ Subsection (e) also uses the broader touching definition that includes contact through the victim’s clothing. The fight in a 243.4(a) case is often about whether the facts belong on the (a) side or the (e) side of that line.

Defenses That Actually Move the Needle

Four defenses come up repeatedly in these cases, and each attacks a different element.

Consent. If the touching was consensual, or if the defendant reasonably believed the other person consented, the “against the will” element fails. This defense usually comes down to competing accounts of what happened.
No restraint beyond the touching itself. If the prosecution can’t show the defendant restricted the victim’s freedom of movement separately from the physical contact, the (a) charge should not stand. The case might survive as a misdemeanor under (e), but the state prison exposure disappears.
No sexual intent. Accidental contact in a crowded space, for example, lacks the required purpose of arousal, gratification, or abuse.
False accusation. Sexual battery cases often lack injury, witnesses, or forensic evidence. Challenging the credibility of the allegation itself is a common defense strategy.

Statute of Limitations

Because 243.4 is on the list of offenses requiring sex offender registration under Penal Code 290(c), the statute of limitations for a felony filing is 10 years from the date of the offense.⁷ Misdemeanor filings carry a shorter deadline. The clock can also be paused in some circumstances, including when the defendant is out of state.

Other Legal Exposure to Know About

The criminal case is not the only front. California Civil Code 1708.5 lets a victim sue in civil court for sexual battery, with a lower standard of proof than a criminal case uses, so an acquittal does not block a civil judgment.⁸ A defendant can face both a prison sentence and a money judgment from the same incident.

For non-citizens, a felony conviction under 243.4(a) carries serious immigration risk. Federal law treats a “crime of violence” with a prison sentence of one year or more as an aggravated felony, which can trigger mandatory deportation and permanently bar re-entry.⁹ Because felony 243.4(a) carries a minimum two-year sentence, any felony conviction here puts a non-citizen’s status at risk. Even a misdemeanor can affect immigration applications on good-moral-character grounds.

Registration also affects custody. Under California Family Code 3030, a person required to register under Penal Code 290 for an offense involving a minor victim cannot receive physical or legal custody, or unsupervised visitation, unless the court specifically finds no significant risk to the child and states its reasons on the record. Even where the offense did not involve a child, the fact of registration can weigh heavily in custody decisions, which California courts make based on the child’s best interests.
