New York Consolidated Laws, Family Court Act - FCT § 325.2. The probable-cause hearing;  order of proceeding

1. The order of a probable-cause hearing held pursuant to section 325.1 or 322.2 shall be as follows:

2. Each witness, whether called by the presentment agency or by the respondent, must, unless he would be authorized to give unsworn evidence at a fact-finding hearing, testify under oath.  Each witness, including any respondent testifying in his own behalf, may be cross-examined.

3. Only non-hearsay evidence shall be admissible to demonstrate reasonable cause to believe that the respondent committed a crime;  except that reports of experts and technicians in professional and scientific fields and sworn statements of the kinds admissible at a hearing upon a felony complaint in a criminal court may be admitted, unless the court determines, upon application of the respondent, that such hearsay evidence is, under the particular circumstances of the case, not sufficiently reliable, in which case the court shall require that the witness testify in person and be subject to cross-examination.

4. Such hearing should be completed at one session.  In the interest of justice, however, it may be adjourned by the court, but no such adjournment may be for more than one court day.
