Full Text of Rule 5.643
Plain-English Summary
Where the court believes a child who is the subject of a petition is mentally disabled or may be mentally ill, it may stay the case and send the child to a court-designated facility for 72-hour treatment and evaluation. The professional in charge reports back in writing.
What happens next depends on that report. If the child does not need intensive treatment, they come back to the juvenile court on or before the end of the 72 hours and the case resumes. If they do, the child may be certified for up to 14 days of involuntary intensive treatment, and the stay of the juvenile proceedings holds for that period. During or at the end of the 14 days, further certification or a conservatorship may be sought, and the juvenile court may keep jurisdiction while those proceedings run.
One branch goes further. Where a child facing a section 602 petition is found gravely disabled, a conservator is appointed, and the professional in charge determines that continuing the delinquency case would be detrimental, the juvenile court must suspend its jurisdiction while the conservatorship lasts. It can pick the matter up again when the conservatorship ends.
Developmental disability follows a parallel track. If the professional finds a developmental disability and recommends a state hospital, the court may direct a commitment petition to be filed in the appropriate court; if not, the child returns within the 72 hours. Juvenile jurisdiction is suspended while the child is subject to that other court’s jurisdiction on a commitment petition or a 90-day remand.
The last part is about a different question — not whether the child is ill, but whether they can take part in their own case. Where there is substantial evidence that a child lacks the present ability to consult with counsel and help prepare a defence with a reasonable degree of rational understanding, or lacks a rational as well as factual understanding of the charges, the court must suspend the proceedings and hold a competence hearing. Evidence is substantial if it raises a reasonable doubt. The court appoints an expert, and the rule spells out who qualifies: a licensed psychiatrist with the stated residency and child-and-adolescent fellowship training, or a licensed clinical, counseling or school psychologist with a doctorate from an accredited institution — in either case with demonstrable experience of child and adolescent development, expertise in their cultural and social characteristics, forensic training reflected in a curriculum vitae, familiarity with juvenile competency standards and available interventions, and proficiency in the child’s preferred language or a certified interpreter and culturally appropriate assessment tools.
Other clinicians are not shut out — they may still take part as consultants or witnesses. After the hearing, the court proceeds as the statute directs.
Advisory Committee Comment
The following comment is published by the Judicial Council of California alongside the rule itself — not commentary from this site.
Welfare and Institutions Code section 709(b) mandates that the Judicial Council develop and adopt rules regarding the qualification of experts to determine competency for purposes of juvenile adjudication. Upon a court finding of incompetency based on a developmental disability, the regional center determines eligibility for services under Division 4.5 of the Lanterman Developmental Disabilities Services (Welf. & Inst. Code, § 4500 et seq.).
Frequently Asked Questions
What can the court do if it doubts a child’s mental health?
It may stay the proceedings and order the child taken to a court-designated, state-approved facility for 72-hour treatment and evaluation. The professional in charge must give the court a written evaluation.
What happens if the child needs intensive treatment?
The child may be certified for up to 14 days of involuntary intensive treatment under the statutory conditions, and the stay of the juvenile proceedings stays in effect throughout.
Is juvenile jurisdiction ever suspended?
Yes. It must be suspended where a child in a section 602 case is found gravely disabled, a conservator is appointed, and the professional in charge determines the delinquency proceedings would be detrimental — and it is suspended while a child is subject to a developmental-disability commitment petition or a 90-day remand.
When must the court hold a competence hearing?
Where there is substantial evidence — enough to raise a reasonable doubt — that the child cannot consult with counsel and assist rationally in preparing a defence, or lacks a rational and factual understanding of the charges. The proceedings are suspended and an expert is appointed.
Who can be appointed as the expert?
A licensed psychiatrist with the specified residency and child-and-adolescent fellowship training, or a licensed clinical, counseling or school psychologist with an accredited doctorate — each with demonstrated child and adolescent experience, forensic training, familiarity with juvenile competency standards, and proficiency in the child’s preferred language or a certified interpreter.
