Section 331.4. Discovery; of prior statements and history of witnesses

1.
  At the commencement of the fact-finding hearing, the presentment  agency
  shall, subject to a protective order, make available to the respondent:
    (a)  any written or recorded statement, including any testimony before
  a grand jury and any examination videotaped pursuant to  section  190.32
  of  the  criminal  procedure  law, made by a person whom the presentment
  agency intends to call as a witness at  the  fact-finding  hearing,  and
  which  relates  to  the  subject matter of the witness's testimony. When
  such a statement includes grand jury testimony, the  presentment  agency
  shall  request  that  the  district  attorney  provide  a  transcript of
  testimony prior to the commencement of the  fact-finding  hearing;  upon
  receiving  such a request, the district attorney shall promptly apply to
  the appropriate criminal court, with written notice to  the  presentment
  agency and the respondent, for a written order pursuant to section three
  hundred  twenty-five  of  the  judiciary  law  releasing a transcript of
  testimony to the presentment agency;
    (b) a record of judgment of conviction of a  witness  the  presentment
  agency  intends  to  call  at the fact-finding hearing if such record is
  known by the presentment agency to exist;
    (c) the existence of any pending criminal action against a witness the
  presentment agency intends to call at the fact-finding hearing,  if  the
  pending criminal action is known by the presentment agency to exist.
    The  provisions  of  paragraphs  (b) and (c) shall not be construed to
  require the presentment agency to fingerprint  a  witness  or  otherwise
  cause the division of criminal justice services or other law enforcement
  agency or court to issue a report concerning a witness.
    2.  At  the  conclusion  of  the  presentment agency's direct case and
  before the commencement of the respondent's direct case, the  respondent
  shall,  subject to a protective order, make available to the presentment
  agency (a) any written or recorded statement made by a person other than
  the respondent whom the respondent intends to call as a witness  at  the
  fact-finding  hearing  and  which  relates  to the subject matter of the
  witness's testimony; (b)  a  record  of  judgment  of  conviction  of  a
  witness,  other than the respondent, the respondent intends to call at a
  hearing if the record of conviction is known by the respondent to exist;
  and (c) the existence of any pending criminal action against a  witness,
  other  than the respondent, the respondent intends to call at a hearing,
  if the pending criminal action is known by the respondent to exist.
    3. Subject to a protective order, at a pre-fact-finding  hearing  held
  upon a motion pursuant to section 330.2, at which a witness is called to
  testify,  each party at the conclusion of the direct examination of each
  of its witnesses, shall, upon request of the other party, make available
  to that party to the extent not previously disclosed:
    (a) any written or recorded statement, including any testimony  before
  a  grand  jury,  made  by  such witness other than the respondent, which
  relates to the subject matter of the witness's testimony.  When  such  a
  statement  includes  grand  jury testimony, the presentment agency shall
  request that the district attorney provide  a  transcript  of  testimony
  prior   to  the  commencement  of  the  pre-fact-finding  hearing;  upon
  receiving such a request, the district attorney shall promptly apply  to
  the  appropriate  criminal court, with written notice to the presentment
  agency and the respondent, for a written order pursuant to section three
  hundred twenty-five of the  judiciary  law  releasing  a  transcript  of
  testimony to the presentment agency;
    (b)  a  record  of a judgment of conviction of such witness other than
  the respondent if the record of conviction is known by  the  presentment
  agency or respondent, as the case may be, to exist; and

    (c)  the existence of any pending criminal action against such witness
  other than the respondent, if the pending criminal action  is  known  by
  the presentment agency or respondent, as the case may be, to exist.
