Cal. WIC § 366.5

The dependency jurisdiction shall be suspended for a child whom the juvenile court declares to be a dual status child based on the joint assessment and recommendation of the county probation department and the child welfare services department pursuant to subparagraph (A) of paragraph (5) of subdivision (e) of Section 241.1. The suspension shall be in effect while the child is a ward of the court. If the jurisdiction established pursuant to Section 601 or 602 is terminated without the need for continued dependency proceedings concerning the child, the juvenile court shall terminate the child’s dual status. If the termination of the Section 601 or 602 jurisdiction is likely and reunification of the child with his or her parent or guardian would be detrimental to the child, the county probation department and child welfare services department shall jointly assess and produce a recommendation regarding whether the court’s dependency jurisdiction shall be resumed.
