When a minor under the age of 18 is accused of committing a crime in California, their case is adjudicated not in the adult criminal justice system, but in the specialized Juvenile Delinquency Court under Welfare & Institutions Code § 602 (W&I 602). The philosophy governing juvenile court is fundamentally distinct from adult criminal court: while the adult system focuses primarily on punishment and retribution, California juvenile jurisprudence is statutorily anchored in rehabilitation, family preservation, and developmental guidance. However, juvenile proceedings are not informal or forgiving. A sustained juvenile petition can result in removal from the family home, commitment to a secure county youth camp, or placement in a secure juvenile facility until age 25. Most gravely, for minors aged 16 or 17 accused of serious felonies, prosecutors can petition the court to transfer the case to adult criminal court under Welfare & Institutions Code § 707.
⚖️ Key Structural Differences Between Juvenile and Adult Court
In California juvenile delinquency proceedings, there are no jury trials and no cash bail. All contested jurisdictional hearings (trials) are decided exclusively by a Superior Court juvenile judge or commissioner (the "bench"). Pretrial detention is decided at an initial Detention Hearing based strictly on public safety, flight risk, or home protection needs. Crucially, minors are not "convicted of crimes"; rather, the court makes a finding that the allegations in the petition are "true," which sustains the petition.
1. Stages of a California Juvenile Delinquency Case
Navigating a juvenile matter in Los Angeles County (such as at Eastlake Juvenile Court, Sylmar Juvenile Court, or Inglewood Juvenile Court) involves distinct statutory stages:
| Juvenile Hearing Stage | Governing Statute | Core Legal Purpose & Burden | Strategic Defense Objectives |
|---|---|---|---|
| Detention Hearing | W&I Code § 632 | Determine whether the minor must remain in Juvenile Hall or can be released to parents pending trial | Present evidence of family supervision, school attendance, counseling enrollment, and community safety plans to secure immediate release home. |
| Jurisdictional Hearing (Trial) | W&I Code § 602 / 701 | Evidentiary trial before a judge to determine if allegations are true beyond a reasonable doubt | Cross-examine witnesses, litigate constitutional suppression motions (PC 1538.5), and present affirmative defenses. |
| Dispositional Hearing (Sentencing) | W&I Code § 702 / 706 | Determine the rehabilitative sentence, custody placement, or probation terms | Advocate for home on probation (HOP), community service, or therapeutic restorative justice programs rather than out-of-home placement. |
| Transfer Hearing (Fitness Hearing) | W&I Code § 707 | Determine whether a 16- or 17-year-old accused of a serious felony should be tried as an adult | Present comprehensive psychological evaluations and developmental expert testimony proving amenability to juvenile rehabilitation. |
2. Adult Transfer Hearings Under W&I § 707
Following the passage of Proposition 57 in 2016 and Senate Bill 1391 in 2018, direct filing of juvenile cases into adult court by prosecutors was abolished, and transfer is prohibited for any youth under age 16 at the time of the alleged offense. For 16- and 17-year-olds accused of serious or violent felonies (such as murder, robbery with a firearm, or carjacking), the prosecutor must file a formal motion requesting a W&I § 707 Transfer Hearing. The juvenile judge must evaluate five mandatory statutory criteria:
- Degree of Criminal Sophistication: Evaluating the minor's cognitive maturity, planning, impulsivity, and the influence of adult co-defendants or peer pressure.
- Rehabilitative Potential Prior to Expiration of Juvenile Jurisdiction: Whether the youth can be successfully rehabilitated before the juvenile court loses jurisdiction (typically at age 25).
- Previous Delinquency History: Evaluating whether the minor has a lengthy record of prior sustained petitions or has failed previous juvenile interventions.
- Success of Previous Rehabilitation Attempts: Examining whether the minor was ever offered community-based counseling or intensive probation in the past.
- Circumstances and Gravity of the Alleged Offense: Analyzing the actual physical harm, weapon use, and vulnerability of the alleged victim.
3. Diversionary Alternatives: W&I § 654 and DEJ (W&I § 790)
Experienced juvenile defense counsel aggressively pursues statutory diversion programs designed to resolve cases without a formal sustained delinquency finding:
- Informal Probation Under W&I § 654: For first-time or low-level misdemeanor offenders, the probation department or court can place the minor on informal supervision for 6 months. Upon successful completion of counseling and community service, the petition is completely dismissed and never filed.
- Deferred Entry of Judgment (DEJ) Under W&I § 790: Available for eligible first-time felony offenders. The minor admits the allegations, but the court defers entering judgment for 12 to 36 months. Upon successful completion of probation, the case is dismissed, the record is sealed, and the arrest is legally deemed never to have occurred.
4. Sealing Juvenile Records Under W&I §§ 781 and 786
Contrary to popular belief, juvenile criminal records do not automatically disappear or vanish when a person turns 18 years old. A sustained juvenile petition remains on California Department of Justice records unless affirmatively sealed. Under W&I § 786, when a minor successfully completes probation, the court must automatically dismiss the petition and seal all court, probation, and police records. For older matters, counsel files a petition under W&I § 781 to permanently destroy juvenile arrest and court records.
