The Judicial Council shall adopt a rule of court effective July 1, 2001, that complies with the requirement of the federal Child Abuse Prevention and Treatment Act (Public Law 93-247) for the appointment of a guardian ad litem, who may be an attorney or a court-appointed special advocate, for a child in cases in which a petition is filed based upon neglect or abuse of the child or in which a prosecution is initiated under the Penal Code arising from neglect or abuse of the child. The rule of court may include guidelines to the courts for determining when an attorney should be appointed rather than a court appointed special advocate, and caseload standards for guardians ad litem.
