(a) General purpose
This rule must be liberally construed in favor of informal disclosures, subject to the right of a party to show privilege or other good cause not to disclose specific material or information.
(b) Duty to disclose police reports
After filing the petition, petitioner must promptly deliver to or make accessible for inspection and copying by the child and the parent or guardian, or their counsel, copies of the police, arrest, and crime reports relating to the pending matter. Privileged information may be omitted if notice of the omission is given simultaneously.
(c) Affirmative duty to disclose
Petitioner must disclose any evidence or information within petitioner’s possession or control favorable to the child, parent, or guardian.
(d) Material and information to be disclosed on request
Except as provided in (g) and (h), petitioner must, after timely request, disclose to the child and parent or guardian, or their counsel, the following material and information within the petitioner’s possession or control:
(1) Probation reports prepared in connection with the pending matter relating to the child, parent, or guardian;
(2) Records of statements, admissions, or conversations by the child, parent, or guardian;
(3) Records of statements, admissions, or conversations by any alleged coparticipant;
(4) Names and addresses of witnesses interviewed by an investigating authority in connection with the pending matter;
(5) Records of statements or conversations of witnesses or other persons interviewed by an investigating authority in connection with the pending matter;
(6) Reports or statements of experts made regarding the pending matter, including results of physical or mental examinations and results of scientific tests, experiments, or comparisons;
(7) Photographs or physical evidence relating to the pending matter; and
(8) Records of prior felony convictions of the witnesses each party intends to call.
(e) Disclosure in section 300 proceedings
Except as provided in (g) and (h), the parent or guardian must, after timely request, disclose to petitioner relevant material and information within the parent’s or guardian’s possession or control. If counsel represents the parent or guardian, a disclosure request must be made through counsel.
(f) Motion for prehearing discovery
If a party refuses to disclose information or permit inspection of materials, the requesting party or counsel may move the court for an order requiring timely disclosure of the information or materials. The motion must specifically and clearly designate the items sought, state the relevancy of the items, and state that a timely request has been made for the items and that the other party has refused to provide them. Each court may by local rule establish the manner and time within which a motion under this subdivision must be made.
(g) Limits on duty to disclose—protective orders
On a showing of privilege or other good cause, the court may make orders restricting disclosures. All material and information to which a party is entitled must be disclosed in time to permit counsel to make beneficial use of them.
(h) Limits on duty to disclose—excision
When some parts of the materials are discoverable under (d) and (e) and other parts are not discoverable, the nondiscoverable material may be excised and need not be disclosed if the requesting party or counsel has been notified that the privileged material has been excised. Material ordered excised must be sealed and preserved in the records of the court for review on appeal.
(i) Conditions of discovery
An order of the court granting discovery under this rule may specify the time, place, and manner of making the discovery and inspection and may prescribe terms and conditions. Discovery must be completed in a timely manner to avoid the delay or continuance of a scheduled hearing.
(j) Failure to comply; sanctions
If at any time during the course of the proceedings the court learns that a person has failed to comply with this rule or with an order issued under this rule, the court may order the person to permit the discovery or inspection of materials not previously disclosed, grant a continuance, prohibit a party from introducing in evidence the material not disclosed, dismiss the proceedings, or enter any other order the court deems just under the circumstances.
(k) Continuing duty to disclose
If subsequent to compliance with these rules or with court orders a party discovers additional material or information subject to disclosure, the party must promptly notify the child and parent or guardian, or their counsel, of the existence of the additional matter.
End

Plain-English Summary

The rule opens by telling the reader how to read it: liberally, in favour of informal disclosures, subject to a party’s right to show privilege or other good cause not to disclose.

Two duties arise without any request. After the petition is filed, the petitioner must promptly deliver or make accessible the police, arrest and crime reports, omitting privileged information only with simultaneous notice of the omission. And the petitioner must disclose any evidence or information in its possession or control favourable to the child, parent, or guardian.

On timely request, eight further categories follow: probation reports, records of statements by the child, parent, guardian or any alleged coparticipant, names and addresses of witnesses interviewed, records of their statements, expert reports including examination and test results, photographs and physical evidence, and records of prior felony convictions of intended witnesses. In dependency, the parent or guardian owes a reciprocal duty on request.

Where disclosure is refused, the requesting party may move for an order, specifically designating the items, stating their relevance, and stating that a timely request was made and refused. Protective orders and excision are available on a showing of privilege or good cause — with excised material sealed and preserved for review on appeal, and everything a party is entitled to disclosed in time for counsel to make beneficial use of it.

Non-compliance carries a range of sanctions: ordering the discovery, a continuance, excluding the undisclosed material, dismissing the proceedings, or any other just order. The duty is continuing — newly discovered material must be notified promptly.

Frequently Asked Questions

What must the petitioner turn over without being asked?

The police, arrest and crime reports relating to the pending matter, promptly after filing the petition — and any evidence or information in its possession or control favourable to the child, parent, or guardian.

What can I get on request?

Probation reports, records of statements by the child, parent, guardian or an alleged coparticipant, names and addresses of interviewed witnesses and records of their statements, expert reports and test results, photographs and physical evidence, and records of prior felony convictions of intended witnesses.

What happens if a party will not disclose?

You may move for an order compelling disclosure. If the court later learns of non-compliance it may order the discovery, grant a continuance, exclude the undisclosed material, dismiss the proceedings, or make any other just order.
