California Senate Bill 145 gave judges discretion over sex offender registration in certain cases involving a minor between the ages of 14 and 17 and an older person no more than 10 years older. Signed by Governor Newsom on September 11, 2020, the law extended to oral sex, anal sex, and sexual penetration the same judicial discretion that had existed for vaginal intercourse since 1944. It did not change the criminal penalties for any underlying offense. It changed only whether a person convicted of one of these offenses is placed on the sex offender registry automatically or whether a judge decides.
What the Law Actually Changed
Before SB-145, California’s registration law treated sexual acts differently based on the act itself. If an adult had voluntary vaginal intercourse with a 14-to-17-year-old and was no more than 10 years older, Penal Code section 261.5 already allowed a judge to weigh the circumstances and decide whether registration served any purpose. Registration in those cases was not automatic.
For voluntary oral sex, anal sex, or sexual penetration under the exact same facts, registration was mandatory. The judge had no choice, even when the prosecutor agreed registration made no sense in the case at hand.
SB-145 eliminated that split. It extended judicial discretion to convictions under Penal Code sections 286(b), 287(b), and 289(h) and (i), bringing them in line with how 261.5 already worked.1California Legislative Information. SB-145 Sex Offenders Registration When the qualifying conditions are met, a judge now evaluates the specifics of the case rather than registering the defendant by default.
Much of the push for the bill came from the disparate effect of the old rule on LGBTQ+ young people. Because the former framework treated oral and anal sex differently from vaginal intercourse, same-sex couples in otherwise identical factual situations faced mandatory registration while opposite-sex couples did not. A 19-year-old convicted of voluntary oral sex with a 17-year-old had to go on the registry; a 19-year-old convicted of voluntary vaginal intercourse with the same 17-year-old might not, depending on what the judge decided.
Criminal Penalties Did Not Change
The most common misconception about SB-145 is that it legalized or softened punishment for sexual activity with minors. It did neither. Every offense covered by the bill carries the same penalties it carried before. The bill answered one narrow question: after conviction and sentencing, does registration happen automatically, or does a judge decide?
The underlying statutes still carry serious consequences:
- Unlawful sexual intercourse under Penal Code 261.5. When the older person is more than three years older than the minor, the offense is punishable as a misdemeanor or felony with up to one year in county jail or a state prison sentence. If the adult is 21 or older and the minor is under 16, a felony conviction carries two, three, or four years in state prison.2California Legislative Information. California Penal Code 261.5
- Sodomy with a minor under Penal Code 286(b). Punishable by state prison or up to one year in county jail. When the adult is over 21 and the minor is under 16, it is automatically a felony.3California Legislative Information. California Penal Code 286
- Oral copulation with a minor under Penal Code 287(b). Same structure: state prison or up to one year in county jail, with a mandatory felony when the adult is over 21 and the minor is under 16.4California Legislative Information. California Penal Code 287
- Sexual penetration with a minor under Penal Code 289(h) and (i). State prison or up to one year in county jail, with a mandatory felony for adults over 21 when the minor is under 16.5California Legislative Information. California Penal Code 289
A conviction under any of these statutes still means prosecution, potential prison, and a criminal record. SB-145 reduces none of those outcomes. The only question it affects is whether the registry gets added on top.
Who Qualifies for Judicial Discretion
Discretion under SB-145 applies only when every one of the following is true:
- The minor was 14, 15, 16, or 17 at the time of the offense.
- The older person was no more than 10 years older than the minor.
- The conviction falls under Penal Code 261.5(c) or (d), 286(b), 287(b), or 289(h) or (i).
- The offense is the person’s only conviction requiring sex offender registration.
All four conditions must be present.1California Legislative Information. SB-145 Sex Offenders Registration If any one fails, if the minor was 13, if the age gap was 11 years, if the person has a prior registrable offense, mandatory registration still applies. The window is deliberately narrow.
When Discretion Does Not Apply
Certain offenses trigger mandatory registration regardless of circumstances, and SB-145 does not touch them. Offenses involving force or violence are the clearest example. A conviction for rape committed through force requires registration and state prison.6LegiScan. Bill Text CA SB145 2019-2020 Regular Session Chaptered
Other mandatory registration offenses include kidnapping with intent to commit a sexual offense, assault with intent to commit a sexual offense, and murder committed during the perpetration of a sexual offense. The full list sits in Penal Code section 290(c).7California Legislative Information. California Penal Code 290 The common thread is conduct that goes beyond a voluntary age-gap situation. Anything involving coercion, predation, or violence falls outside the discretionary framework entirely.
How a Judge Decides
When the conditions are met, the judge works under Penal Code 290.006. The court must consider the nature of the offense, the age and number of victims, and whether the person has other criminal convictions. If the judge orders registration, the reasons must be stated on the record.8California Legislative Information. California Penal Code 290.006
Discretion is not a guarantee of no registration. It means the judge evaluates whether the registry fits the case rather than imposing it reflexively. When a judge does order discretionary registration under 290.006, the default placement is Tier 1 under California’s tiered registry system unless the court specifically finds a higher tier appropriate and explains that finding on the record.8California Legislative Information. California Penal Code 290.006 Tier 1 carries a 10-year minimum registration period for adult convictions and is the first tier eligible for a removal petition.9California Department of Justice. Sex Offender Tiering (SB 384) FAQs
Why It Matters at Sentencing
Because registration under SB-145 is now a discretionary call, the sentencing hearing is where the issue is decided. The factors in 290.006, the nature of the offense, the age and number of victims, the defendant’s criminal history, give a judge a framework for declining registration when the facts support it. Concrete evidence that the contact was voluntary, that the age gap was small, and that no exploitation existed is what gives the judge something to work with. Psychological evaluations addressing recidivism risk can also inform the decision.
The fight over registration is separate from the fight over the underlying conviction. Even when a plea or conviction is unavoidable, the registration question remains open under SB-145 for anyone who meets the four conditions, and that question has its own stakes long after the criminal sentence is served. Once the sentencing judge has decided, the opportunity to shape that decision is gone.
