(b) The evaluator selected by the court shall personally examine the minor, conduct appropriate psychological or mental health screening, assessment, or testing, according to a uniform protocol developed by the county mental health department, and prepare and submit to the court a written report indicating his or her findings and recommendations to guide the court in determining whether the minor has a serious mental disorder or is seriously emotionally disturbed, as described in Section 5600.3.  If the minor is detained, the examination shall occur within three court days of the court's order of referral for evaluation, and the evaluator's report shall be submitted to the court not later than five court days after the evaluator has personally examined the minor, unless the submission date is extended by the court for good cause shown.

(c) Based on the written report by the evaluator or the regional center, the court shall determine whether the minor has a serious mental disorder or is seriously emotionally disturbed, as described in Section 5600.3, or has a developmental disability, as defined in Section 4512.  If the court determines that the minor has a serious mental disorder, is seriously emotionally disturbed, or has a developmental disability, the case shall proceed as described in Section 713.  If the court determines that the minor does not have a serious mental disorder, is not seriously emotionally disturbed, or does not have a developmental disability, the matter shall proceed without the application of Section 713 and in accordance with all other applicable provisions of law.

(d) This section shall not be construed to interfere with the legal authority of the juvenile court or of any other public or private agency or individual to refer a minor for mental health evaluation or treatment as provided in Section 370, 635.1, 704, 741, 5150, 5694.7, 5699.2, 5867.5, or 6551 of this code, or in Section 4011.6 of the Penal Code.
