Section 835. Sequence of hearings

(a) Upon completion of the fact-finding
  hearing, the dispositional hearing may commence  immediately  after  the
  required findings are made.
    (b)  Reports prepared by the probation service for use by the court at
  any time prior to the making of an order of disposition shall be  deemed
  confidential  information  furnished  to  the court which the court in a
  proper case may, in its discretion, withhold from or disclose  in  whole
  or  in  part  to  the law guardian, counsel, party in interest, or other
  appropriate person. Such reports may not be furnished to the court prior
  to the completion of a fact-finding  hearing,  but  may  be  used  in  a
  dispositional hearing.
