(a) The superintendent of a facility may petition the district court or the division of the juvenile court department in whose jurisdiction the facility is located for the commitment to said facility and retention of any patient at said facility whom said superintendent determines that the failure to hospitalize would create a likelihood of serious harm by reason of mental illness.

(b) The medical director of the Bridgewater state hospital, the commissioner of mental health, or with the approval of the commissioner of mental health, the superintendent of a facility, may petition the district court or the division of the juvenile court department in whose jurisdiction the facility or hospital is located for the commitment to the Bridgewater state hospital of any male patient at said facility or hospital when it is determined that the failure to hospitalize in strict security would create a likelihood of serious harm by reason of mental illness.

(c) Whenever a court receives a petition filed under any provisions of this chapter for an order of commitment of a person to a facility or to the Bridgewater state hospital, such court shall notify the person, and his nearest relative or guardian, of the receipt of such petition and of the date a hearing on such petition is to be held.
