Oral Copulation on Minors – PC 287
An allegation of oral copulation involving a minor is among the most serious criminal accusations a person can face in California. A conviction can result in years or even decades in state prison, mandatory sex offender registration, substantial restrictions on future employment opportunities, immigration consequences for noncitizens, and lasting damage to a person’s reputation and personal relationships. In certain circumstances involving very young children or specific aggravating factors, a defendant may even face a sentence of life in prison.
When law enforcement begins investigating a suspected violation of Penal Code 287 involving a minor, prosecutors often devote significant resources to building a case. These investigations may involve forensic interviews, electronic communications, medical evidence, social media records, witness statements, and extensive digital forensic examinations. Because the stakes are extraordinarily high, anyone under investigation or charged with oral copulation involving a minor should seek experienced legal representation as early as possible.
The Law Office of Kristine Koo represents individuals throughout Orange County who are facing serious sex crime allegations. Attorney Kristine Koo is a former prosecutor and former public defender who has handled complex criminal cases at every stage of the justice system. Her experience provides valuable insight into how prosecutors investigate, evaluate, and litigate serious felony sex offense allegations involving minors.
Penal Code 287 and Allegations Involving Minors
California Penal Code 287 criminalizes oral copulation, which generally involves contact between the mouth of one person and the sexual organ or anus of another person. When the alleged victim is under the age of 18, the offense becomes significantly more serious because California law does not recognize a minor’s legal ability to consent to the conduct. As a result, prosecutors do not need to prove that force was used in every case involving a minor. The fact that the alleged victim was under the age of 18 may be enough to support criminal charges under certain provisions of the statute.
The severity of a Penal Code 287 charge involving a minor depends on numerous factors. Prosecutors will examine the age of the alleged victim, the age difference between the parties, whether force or fear was allegedly involved, whether multiple individuals participated in the conduct, and whether any sentencing enhancements or related offenses apply. These factors can dramatically affect the potential punishment a defendant faces.
Although every case is unique, allegations involving younger children generally carry significantly harsher penalties than allegations involving older minors. Likewise, allegations involving force, duress, violence, or fear often expose a defendant to substantially greater prison terms.
Oral Copulation With a Minor Under 18
Penal Code 287(b)(1) addresses oral copulation involving a person who is under the age of 18. Depending upon the circumstances, prosecutors may pursue either misdemeanor or felony charges. Even in situations where the parties allegedly engaged in the conduct voluntarily, the prosecution may still file charges because California law does not permit minors to legally consent to oral copulation.
A conviction under this section can expose a defendant to incarceration, probation conditions, substantial fines, and other serious consequences. The specific sentence imposed will depend on the facts of the case, the defendant’s criminal history, and the circumstances surrounding the alleged offense.
More severe consequences may arise under Penal Code 287(b)(2), which applies when the defendant is over the age of 21 and the alleged victim is under the age of 16. California lawmakers have determined that a significant age disparity increases the seriousness of the offense, and prosecutors frequently pursue felony punishment in these cases. Convictions may result in state prison sentences and other long term consequences that can follow a person for the rest of their life.
Cases Involving Children Under Fourteen Years Old
California law imposes particularly severe punishment when allegations involve very young children. Under Penal Code 287(c)(1), oral copulation involving a child under the age of 14 who is more than ten years younger than the accused is punishable by three, six, or eight years in state prison.
Cases involving children under fourteen often receive heightened attention from prosecutors and law enforcement agencies. Investigators may seek extensive evidence in an effort to establish the age of the child, the circumstances of the alleged conduct, and the identity of the accused. Because these cases frequently involve serious prison exposure, a thorough and aggressive defense is essential.
Allegations Involving Force, Violence, Duress, Menace, or Fear
The potential punishment increases dramatically when prosecutors allege that oral copulation occurred through force, violence, duress, menace, or fear of immediate bodily injury. These allegations can transform an already serious case into one carrying decades of prison exposure.
When the alleged victim is under the age of fourteen, Penal Code 287(c)(2)(A) provides for state prison sentences of eight, ten, or twelve years. If the alleged victim is fourteen years of age or older, Penal Code 287(c)(2)(B) provides for sentences of six, eight, or ten years in state prison.
In many cases, allegations involving force or fear become a central battleground between the prosecution and the defense. Prosecutors must prove the allegation beyond a reasonable doubt, and the evidence supporting those claims must be carefully examined. Witness statements, forensic evidence, prior communications, and investigative procedures often become critical areas of focus.
Acting in Concert Allegations
Certain cases involve allegations that more than one individual participated in the offense. Under Penal Code 287(d), enhanced penalties may apply when prosecutors allege that a defendant voluntarily acted together with another person during the commission of the offense.
If the alleged victim is under the age of fourteen, a conviction can result in a prison sentence of ten, twelve, or fourteen years. If the alleged victim is fourteen years of age or older, the potential sentence may be eight, ten, or twelve years in state prison.
These cases are often legally complex because prosecutors may attempt to hold one defendant responsible for the conduct of another. Careful analysis of witness testimony, electronic evidence, and the actions of each participant is often essential in developing an effective defense strategy.
Can a Defendant Face a Life Sentence?
Yes. While not every Penal Code 287 case involving a minor carries life imprisonment, certain allegations may expose a defendant to a life sentence under California law.
One example is Penal Code 288.7(b), which applies when a person eighteen years of age or older engages in oral copulation with a child who is ten years old or younger. A conviction under this statute carries a sentence of fifteen years to life in state prison.
Another statute that may arise in certain cases is Penal Code 269, California’s aggravated sexual assault of a child law. This statute may apply when the alleged victim is under fourteen years old, the defendant is at least seven years older than the child, and the conduct falls within one of the qualifying sexual offenses. A conviction under Penal Code 269 carries a sentence of fifteen years to life.
In some circumstances, prosecutors may also seek enhanced punishment under California’s One Strike law, Penal Code 667.61. Depending on the facts alleged and the enhancements proven, the potential punishment can include fifteen years to life, twenty five years to life, or even life without the possibility of parole in exceptionally aggravated cases. Determining whether a life sentence statute applies requires careful legal analysis and should be evaluated immediately after charges are filed or an investigation begins.
Multiple charges and potential life sentences.
Oral copulation allegations involving minors frequently overlap with other California sex offense statutes. Prosecutors commonly file multiple charges arising from the same investigation in an effort to increase potential punishment and strengthen their negotiating position.
For example, prosecutors may allege violations of Penal Code 288, which criminalizes lewd or lascivious acts with a child. In cases involving repeated allegations over an extended period of time, prosecutors may pursue charges under Penal Code 288.5, California’s continuous sexual abuse of a child statute. Cases involving very young children may also result in allegations under Penal Code 269 or Penal Code 288.7, both of which carry potential life sentences.
Additionally, a conviction for many sex offenses involving minors may trigger registration requirements under California’s sex offender registration laws. The consequences of registration can affect housing, employment opportunities, and other aspects of daily life long after a criminal sentence has been completed.
Defending Against Allegations of Oral Copulation Involving a Minor
Every criminal case is different, and successful defense strategies depend upon the specific facts involved. However, prosecutors must still prove every element of the charged offense beyond a reasonable doubt. A defense attorney’s role is to carefully examine the evidence, identify weaknesses in the prosecution’s case, and protect the constitutional rights of the accused.
In some cases, the defense may focus on challenging the credibility of witnesses or exposing inconsistencies in statements made during the investigation. In other cases, the defense may involve scrutinizing digital evidence, forensic examinations, or the methods used by law enforcement officers during interviews and searches. Constitutional issues involving unlawful searches, improper interrogations, or violations of due process rights can also play an important role.
Because allegations involving minors often rely heavily on statements and interpretations of events, a thorough investigation by the defense is frequently essential. Early intervention can help preserve evidence, locate witnesses, and identify legal issues before they become more difficult to address.
Why Experience Matters In Serious Sex Crime Cases
Sex crime allegations involving minors require a defense attorney who understands both the legal and practical realities of these highly sensitive cases.
