Oral Copulation by Force Lawyers (PC 287)

A single accusation can cost you your career, your family, and your freedom before you ever step inside a courtroom.

Charges under Penal Code § 287 are among the most aggressively prosecuted offenses in California. Prosecutors treat these cases as high-priority, and the consequences of a conviction reach far beyond prison time. Sex offender registration, loss of professional licenses, immigration consequences, and a permanent record that follows you everywhere you go. These are the realities that make early, experienced defense representation critical.

But here’s what most people don’t realize when they’re first accused: the prosecution’s case is rarely as strong as it appears. These charges often rest on one person’s account, without corroborating physical evidence, and the legal standard for proving force, duress, or menace is more demanding than most people think. The question is whether the prosecution can actually prove every element beyond a reasonable doubt.

Our team at The Nieves Law Firm Criminal Defense Attorneys has defended clients facing serious sex crime allegations across the Bay Area. We understand how these cases are investigated, how they’re charged, and where the prosecution’s theory is most vulnerable. If you’re facing a PC 287 charge, the steps you take right now will shape everything that follows.

What Penal Code § 287 Actually Prohibits

Penal Code § 287 defines oral copulation as any contact, however slight, between the mouth of one person and the sexual organ or anus of another person.¹ The statute was formerly numbered as Penal Code § 288a and was renumbered effective January 1, 2019.²

The statute is broad, covering multiple scenarios across its subdivisions. The most serious charges fall under § 287(b)(1), which criminalizes oral copulation accomplished by means of force, violence, duress, menace, or fear of immediate and unlawful bodily injury.³ But other subdivisions address different circumstances:

§ 287(c)(1) covers situations where the other person is incapable of giving legal consent because of a mental disorder or developmental or physical disability.⁴

§ 287(d)(1) applies when the other person is unconscious of the nature of the act and this is known to the defendant.⁵

§ 287(e) addresses situations where the other person is prevented from resisting by an intoxicating, anesthetic, or controlled substance.⁶

§ 287(h) and (i) address acts involving minors, with § 287(h) covering victims under 18 and § 287(i) covering victims under 16 when the defendant is 21 or older.⁷

While this page focuses primarily on force-based charges under § 287(b)(1) because they carry the most severe penalties and are the most commonly defended, the defense strategies and legal principles discussed here apply across many of these subdivisions.

What Prosecutors Must Prove

Under CALCRIM No. 1015, the prosecution must establish every element of this offense beyond a reasonable doubt.⁸ That means each component must be proven individually, and a failure on any single element requires an acquittal.

An Act of Oral Copulation Occurred

The prosecution must first prove that the defendant committed an act of oral copulation with another person.⁹ Under the jury instruction, this means any contact, however slight, between the mouth of one person and the sexual organ or anus of another.¹⁰ Penetration is not required. In practice, this element often depends entirely on the accuser’s testimony, particularly in cases without forensic evidence. Where there is no DNA, no physical injury, and no third-party witnesses, the prosecution is asking a jury to accept one person’s account as proof beyond a reasonable doubt.

The Act Was Accomplished Against the Other Person’s Will

This is where the prosecution’s burden becomes most demanding. They must prove the act was accomplished against the will of the other person.¹¹ “Against the will” is not the same as “without enthusiastic agreement.” The prosecution must show the absence of consent, which CALCRIM defines as positive cooperation in act or attitude pursuant to an exercise of free will, with knowledge of the nature of the act.¹²

Force, Violence, Duress, Menace, or Fear Was Used

The prosecution must also prove the specific means by which the act was accomplished. Under CALCRIM No. 1015, this requires proof of one or more of the following¹³:

Force means enough physical force to overcome the other person’s will. This is more than the physical effort inherent in the act itself. The prosecution must show force beyond what would be involved in the act of oral copulation itself.

Duress means a direct or implied threat of force, violence, danger, hardship, or retribution sufficient to coerce a reasonable person to perform or submit to the act. The jury may consider the totality of the circumstances, including the age of the other person and their relationship to the defendant.¹⁴

Menace means a threat, statement, or act showing an intent to injure someone.¹⁵

Fear of immediate and unlawful bodily injury means the other person actually and reasonably feared being physically harmed.¹⁶

The distinction between these terms matters enormously at trial. A prosecutor who cannot clearly establish which form of coercion was used, and prove it with evidence, faces a significant hurdle.

The Consent Defense and Why It Matters More Than Any Other Element

In our experience defending PC 287 cases, consent is the central battleground in the vast majority of prosecutions involving adults. This is not a technical defense or a legal loophole. It reflects the reality that many of these cases arise from encounters where the parties knew each other, where there was some level of prior relationship or communication, and where the question of what actually happened is genuinely disputed.

California law defines consent as positive cooperation in act or attitude pursuant to an exercise of free will.¹⁷ The person must act freely and voluntarily and have knowledge of the nature of the act. Critically, the absence of resistance does not automatically mean consent, but the prosecution still bears the burden of proving the act was nonconsensual.

What makes this defense so significant is the standard of proof. The defendant does not have to prove consent occurred. The prosecution must prove, beyond a reasonable doubt, that consent did not exist. When the evidence includes text messages, prior interactions, voluntary meeting, or post-encounter communications that suggest a consensual relationship, the prosecution’s task becomes substantially harder.

There is an important limitation: consent is not a defense to charges involving minors under § 287(h) and (i), or to charges involving persons incapable of consent under § 287(c).

Penalties and Sentencing

The penalties for a PC 287 conviction vary significantly depending on which subdivision is charged and the age of the alleged victim.

Force-Based Offenses (§ 287(b)(1))

In Concert by Force (§ 287(b)(2))

Other Subdivisions

All force-based violations under § 287(b) are straight felonies. They are not wobblers and cannot be reduced to misdemeanors.¹⁸

The One Strike Law and Indeterminate Sentencing

One of the most consequential aspects of a PC 287(b) prosecution is the potential application of the “One Strike” law under Penal Code § 667.61.¹⁹ This sentencing scheme can transform what would otherwise be a determinate prison term into an indeterminate life sentence, and many defendants don’t learn about it until after they’ve been charged.

The One Strike law applies when a qualifying sex offense is committed under certain aggravating circumstances. For oral copulation by force, the following scenarios can trigger indeterminate sentencing²⁰:

25 years to life may apply when the offense involves kidnapping, burglary with intent to commit a sex offense, tying or binding the victim, or when the defendant has a prior conviction for a specified sex offense.

15 years to life may apply when the offense involves use of a dangerous or deadly weapon, multiple victims in the current case, or infliction of great bodily injury.

The practical significance is enormous. A defendant charged with PC 287(b)(1) who is also alleged to have used a weapon or committed the offense during a burglary is no longer facing 3 to 8 years. They are facing 15 to 25 years to life. This is why understanding the full scope of the charging document, including every enhancement and special allegation, is essential from the very first court appearance.

Enhancements That Increase Exposure

Beyond the One Strike law, several additional enhancements can apply to PC 287 cases:

A conviction under § 287(b)(1) also qualifies as both a serious felony and a violent felony under California’s Three Strikes law.^{21 22} This means it counts as a strike, and any future felony conviction would result in a presumptively doubled sentence. A third strike could result in 25 years to life in state prison.

Sex Offender Registration

A conviction under most subdivisions of PC 287 requires mandatory registration as a sex offender under Penal Code § 290.²³ California’s tiered registration system, enacted through SB 384 and effective January 1, 2021, assigns registrants to one of three tiers²⁴:

Tier 1 requires a minimum of 10 years of registration. This tier generally applies to less serious offenses.

Tier 2 requires a minimum of 20 years. Some non-force subdivisions of § 287 may fall into this category.

Tier 3 requires lifetime registration. Force-based offenses under § 287(b)(1) are classified as Tier 3 offenses, meaning lifetime registration with no ability to petition for removal from the registry.²⁵

Registration requirements include providing your address to local law enforcement, updating that information annually (and within five working days of any address change), and appearing in person at your local law enforcement agency. Your name, photograph, and address become part of a publicly accessible database.

The registration obligation alone can be more devastating than the prison sentence for many working professionals. It affects where you can live, where you can work, and how your community perceives you for the rest of your life.

Defense Strategies Our Team Pursues

Every PC 287 case has a unique set of facts, and the defense approach must be tailored to those facts. Here are the strategies our attorneys evaluate in every case.

Challenging the Evidence of Force

The prosecution must prove force, duress, menace, or fear as a separate element from the act itself. In many cases, the evidence of force is limited to the accuser’s testimony. Our team examines whether the alleged force goes beyond what is inherent in the act, whether the accuser’s description of force is consistent across multiple statements, and whether physical evidence (or its absence) supports or contradicts the claim.

Consider a scenario where the accuser describes being physically overpowered, but a SART exam conducted hours later shows no bruising, no defensive injuries, and no physical findings consistent with force. That gap between the allegation and the physical evidence is something a jury needs to evaluate.

Investigating Motive to Fabricate

Sex crime allegations are uniquely susceptible to false accusations because they often occur in private settings with no witnesses. Our investigators look for motives that could explain a false allegation: custody disputes, relationship breakdowns, financial incentives from potential civil lawsuits, attempts to cover up infidelity, or retaliation.

We have handled cases where text messages sent after the alleged incident directly contradicted the accuser’s claim that the encounter was nonconsensual. Digital evidence, social media activity, and communication records can be powerful tools for exposing fabrication.

Forensic Evidence Challenges

Our team works with forensic experts to scrutinize the prosecution’s physical evidence. This includes challenging DNA analysis methodology, identifying chain-of-custody failures, questioning the interpretation of SART exam findings, and highlighting the absence of corroborating forensic evidence where the allegations would predict its presence.

Mistaken Identity

In cases involving strangers or encounters in low-visibility environments such as parties, bars, or nightclubs, identification errors are a real possibility. We challenge eyewitness identification procedures, present alibi evidence, and use DNA evidence (or its absence) to exclude our client.

Constitutional Violations

Evidence obtained through illegal searches, statements taken without proper Miranda warnings, or identification procedures that were unduly suggestive can all be challenged through pretrial motions. A successful suppression motion under Penal Code § 1538.5 can eliminate key evidence from the prosecution’s case, sometimes making the remaining evidence insufficient to proceed.²⁶

Challenging Credibility Through Inconsistencies

Accusers in sex crime cases typically give multiple statements: to friends, to police, at the preliminary hearing, and at trial. Our attorneys meticulously compare every version of events, identifying inconsistencies in timing, details, sequence, and the description of force. Even small discrepancies can create reasonable doubt when the entire case rests on one person’s account.

Collateral Consequences Beyond Prison

Immigration

For non-citizens, a conviction under PC 287(b) is almost certainly an aggravated felony under federal immigration law, triggering mandatory deportation with no eligibility for cancellation of removal or most other forms of relief.²⁷ Even lawful permanent residents with decades of U.S. residency face removal proceedings. Our team coordinates with immigration counsel when a client’s status is at risk, because the criminal defense strategy must account for immigration consequences from the outset.

Employment and Professional Licensing

A felony sex offense conviction is disqualifying for most professional licenses in California, including those in healthcare, education, law, finance, and real estate. Many employers conduct background checks that will reveal both the conviction and the sex offender registration. For working professionals, the career consequences can be permanent.

Custody and Family Law

Under Family Code § 3030, a conviction for certain sex offenses creates a presumption against custody.²⁸ This can fundamentally alter a parent’s relationship with their children, sometimes permanently.

Firearms

A felony conviction permanently prohibits firearm ownership under both California and federal law.²⁹

Where Your Case Will Be Heard

Felony sex crime cases in Alameda County are typically prosecuted at the Rene C. Davidson Courthouse at 1225 Fallon Street in Oakland. The Alameda County District Attorney’s Office assigns these cases to a dedicated Sexual Assault Unit with prosecutors who handle sex crime cases exclusively. Bail for force-based oral copulation charges is typically set at $100,000 or higher under the Alameda County Bail Schedule.

Cases originating in other parts of the Bay Area will be heard in the county where the alleged offense occurred. Our team regularly appears in courthouses across the region, including Santa Clara County, Contra Costa County, San Francisco County, Sacramento County, Solano County, and San Joaquin County.

Related Offenses

Prosecutors sometimes file PC 287 charges alongside other serious offenses, or the facts may support alternative charges:

Understanding the full charging landscape is essential because each additional charge carries its own penalties, and some combinations trigger enhancement provisions that dramatically increase sentencing exposure.
