§ 751. Order dismissing petition. If the allegations of a petition
under this article are not established, the court shall dismiss the
petition. The court may in its discretion dismiss a petition under this
article, in the interests of justice where attempts have been made to
adjust the case as provided for in sections seven hundred thirty-five
and seven hundred forty-two of this article and the probation service
has exhausted its efforts to successfully adjust such case as a result
of the petition's failure to provide reasonable assistance to the
probation service.
