Section 355.

(a) At the jurisdictional hearing, the court shall first consider only the question whether the minor is a person described by Section 300. Any legally admissible evidence that is relevant to the circumstances or acts that are alleged to bring the minor within the jurisdiction of the juvenile court is admissible and may be received in evidence. Proof by a preponderance of evidence must be adduced to support a finding that the minor is a person described by Section 300. Objections that could have been made to evidence introduced shall be deemed to have been made by any parent or guardian who is present at the hearing and unrepresented by counsel, unless the court finds that the parent or guardian has made a knowing and intelligent waiver of the right to counsel. Objections that could have been made to evidence introduced shall be deemed to have been made by any unrepresented child.

(b) A social study prepared by the petitioning agency, and hearsay evidence contained in it, is admissible and constitutes competent evidence upon which a finding of jurisdiction pursuant to Section 300 may be based, to the extent allowed by subdivisions (c) and (d).

(1) For the purposes of this section, "social study" means any written report furnished to the juvenile court and to all parties or their counsel by the county probation or welfare department in any matter involving the custody, status, or welfare of a minor in a dependency proceeding pursuant to Article 6 (commencing with Section 300) to Article 12 (commencing with Section 385), inclusive.

(2) The preparer of the social study shall be made available for cross-examination upon a timely request by any party. The court may deem the preparer available for cross-examination if it determines that the preparer is on telephone standby and can be present in court within a reasonable time of the request.

(3) The court may grant a reasonable continuance not to exceed 10 days upon request by any party if the social study is not provided to the parties or their counsel within a reasonable time before the hearing.

(c) (1) If any party to the jurisdictional hearing raises a timely objection to the admission of specific hearsay evidence contained in a social study, the specific hearsay evidence shall not be sufficient by itself to support a jurisdictional finding or any ultimate fact upon which a jurisdictional finding is based, unless the petitioner establishes one or more of the following exceptions:

(A) The hearsay evidence would be admissible in any civil or criminal proceeding under any statutory or decisional exception to the prohibition against hearsay.

(B) The hearsay declarant is a minor under 12 years of age who is the subject of the jurisdictional hearing. However, the hearsay statement of a minor under 12 years of age shall not be admissible if the objecting party establishes that the statement is unreliable because it was the product of fraud, deceit, or undue influence.

(C) The hearsay declarant is a peace officer as defined by Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code, a health practitioner described in paragraphs (22) to (29), inclusive, of subdivision (a) of Section 11165.7 of the Penal Code, a social worker licensed pursuant to Chapter 14 (commencing with Section 4991) of Division 2 of the Business and Professions Code, or a teacher who holds a credential pursuant to Chapter 2 (commencing with Section 44200) of Part 25 of Division 3 of Title 2 of the Education Code. For the purpose of this subdivision, evidence in a declaration is admissible only to the extent that it would otherwise be admissible under this section or if the declarant were present and testifying in court.

(D) The hearsay declarant is available for cross-examination. For purposes of this section, the court may deem a witness available for cross-examination if it determines that the witness is on telephone standby and can be present in court within a reasonable time of a request to examine the witness.

(2) For purposes of this subdivision, an objection is timely if it identifies with reasonable specificity the disputed hearsay evidence and it gives the petitioner a reasonable period of time to meet the objection prior to a contested hearing.

(d) This section shall not be construed to limit the right of any party to the jurisdictional hearing to subpoena a witness whose statement is contained in the social study or to introduce admissible evidence relevant to the weight of the hearsay evidence or the credibility of the hearsay declarant.
