New York Criminal Procedure Law Section 660.20 - Examination of witnesses conditionally; grounds for order.

660.20  Examination of witnesses conditionally; grounds for order.
An  order  directing  examination  of  a witness conditionally must be
  based upon the ground that there is reasonable  cause  to  believe  that
  such witness:
1.     Possesses  information  material  to  the  criminal  action  or
  proceeding in issue; and
2.  Will not be amenable or responsive to legal process  or  available
  as a witness at a time when his testimony will be sought, either because
  he is:
(a)   About to leave the state and not return for a substantial period
  of time; or
(b)  Physically ill or incapacited.
