"(c) If a parent or legal custodian of the child is available but refuses to consent to the necessary treatment, including immunization, a court order shall be required unless the situation meets the definition of an emergency in s. 743.064 or the treatment needed is related to suspected abuse, abandonment, or neglect of the child by a parent, caregiver, or legal custodian. In such case, the department shall have the authority to consent to necessary medical treatment. This authority is limited to the time reasonably necessary to obtain court authorization."
