§ 738. Issuance of warrant for respondent or other person legally
responsible for care. The court may issue a warrant, directing that the
respondent or other person legally responsible for his care or with whom
he is domiciled be brought before the court, when a petition is filed
with the court under this article and it appears that

(a) the summons cannot be served; or

(b) the respondent or other person has refused to obey the summons; or

(c) the respondent or other person is likely to leave the
jurisdiction; or

(d) a summons, in the court's opinion, would be ineffectual; or

(e) a respondent on bail or on parole has failed to appear.

A warrant issued for a respondent under this section shall expire at
the end of six months from the date of its issuance, unless extended for
an additional period of not more than six months upon application by the
petitioner for good cause shown.
