Text sizeJump to: (a) (b) (c) (d)

(a) Application of rules (§§ 200–945) The rules in this division solely apply to every action and proceeding to which the juvenile court law (Welf. & Inst. Code, div. 2, pt. 1, ch. 2, § 200 et seq.) applies, unless they are explicitly made applicable in any other action or proceeding. The rules in this division do not apply to an action or proceeding heard by a traffic hearing officer, nor to a rehearing or appeal from a denial of a rehearing following an order by a traffic hearing officer.

(b) Authority for and purpose of rules (Cal. Const., art. VI, §§ 6, 265)

The Judicial Council adopted the rules in this division under its constitutional and statutory authority to adopt rules for court administration, practice, and procedure that are not inconsistent with statute. These rules implement the purposes of the juvenile court law by promoting uniformity in practice and procedure and by providing guidance to judicial officers, attorneys, social workers, probation officers, and others participating in the juvenile court.

Unless the context otherwise requires, these preliminary provisions and the following rules of construction govern the construction of these rules:

(1) Insofar as these rules are substantially the same as existing statutory provisions relating to the same subject matter, these rules must be construed as restatements of those statutes; and

(2) Insofar as these rules may add to existing statutory provisions relating to the same subject matter, these rules must be construed so as to implement the purposes of the juvenile court law.

(d) Severability clause

If a rule or a subdivision of a rule in this division is invalid, all valid parts that are severable from the invalid part remain in effect. If a rule or a subdivision of a rule in this division is invalid in one or more of its applications, the rule or subdivision remains in effect in all valid applications that are severable from the invalid applications.

End

Plain-English Summary

The reach is stated narrowly: the rules in this division apply solely to actions and proceedings to which the juvenile court law applies, unless explicitly made applicable elsewhere. Two matters are excluded outright — anything heard by a traffic hearing officer, and a rehearing or appeal from the denial of a rehearing after a traffic hearing officer’s order.

The authority is the Judicial Council’s constitutional and statutory power to adopt rules for court administration, practice and procedure that are not inconsistent with statute. The stated purpose is practical: promoting uniformity and guiding judicial officers, attorneys, social workers, probation officers and others in the juvenile court.

Two rules of construction follow, and they resolve the usual tension between a rule and the statute behind it. Where these rules are substantially the same as existing statutory provisions on the same subject, they are construed as restatements of those statutes. Where they add to the statutes, they are construed so as to implement the purposes of the juvenile court law.

The severability clause works at two levels: an invalid rule or subdivision leaves the valid severable parts in effect, and a rule invalid in some applications remains in effect in the valid ones that are severable.

Frequently Asked Questions

Which cases do the Juvenile Rules apply to?

Solely to actions and proceedings to which the juvenile court law applies, unless a rule is explicitly made applicable elsewhere — and not to matters heard by a traffic hearing officer or rehearings and appeals from those.

How are these rules read against the statutes?

Where substantially the same as an existing statutory provision on the same subject, a rule is construed as a restatement of that statute. Where it adds to the statute, it is construed so as to implement the purposes of the juvenile court law.

What if part of a rule is invalid?

All valid parts severable from the invalid part remain in effect, and a rule invalid in some applications remains in effect in the valid applications that are severable from them.
