N.Y. Criminal Procedure Law § 210.45 – Motion to dismiss indictment; procedure

1. A motion to dismiss an indictment pursuant to section 210.20 must be made in writing and upon reasonable notice to the people. If the motion is based upon the existence or occurrence of facts, the motion papers must contain sworn allegations thereof, whether by the defendant or by another person or persons. Such sworn allegations may be based upon personal knowledge of the affiant or upon information and belief, provided that in the latter event the affiant must state the sources of such information and the grounds of such belief. The defendant may further submit documentary evidence supporting or tending to support the allegations of the moving papers.
2. The people may file with the court, and in such case must serve a copy thereof upon the defendant or his counsel, an answer denying or admitting any or all of the allegations of the moving papers, and may further submit documentary evidence refuting or tending to refute such allegations.
3. After all papers of both parties have been filed, and after all documentary evidence, if any, has been submitted, the court must consider the same for the purpose of determining whether the motion is determinable without a hearing to resolve questions of fact.
4. The court must grant the motion without conducting a hearing if:
1. (a) The moving papers allege a ground constituting legal basis for the motion pursuant to subdivision one of section 210.20; and
2. (b) Such ground, if based upon the existence or occurrence of facts, is supported by sworn allegations of all facts essential to support the motion; and
3. (c) The sworn allegations of fact essential to support the motion are either conceded by the people to be true or are conclusively substantiated by unquestionable documentary proof.
5. The court may deny the motion without conducting a hearing if:
1. (a) The moving papers do not allege any ground constituting legal basis for the motion pursuant to subdivision one of section 210.20; or
2. (b) The motion is based upon the existence or occurrence of facts, and the moving papers do not contain sworn allegations supporting all the essential facts; or
3. (c) An allegation of fact essential to support the motion is conclusively refuted by unquestionable documentary proof.
6. If the court does not determine the motion pursuant to subdivision four or five, it must conduct a hearing and make findings of fact essential to the determination thereof. The defendant has a right to be present in person at such hearing but may waive such right.
7. Upon such a hearing, the defendant has the burden of proving by a preponderance of the evidence every fact essential to support the motion.
8. When the court dismisses the entire indictment without authorizing resubmission of the charge or charges to a grand jury, it must order that the defendant be discharged from custody if he is in the custody of the sheriff, or if he is at liberty on bail it must exonerate the bail.
9. When the court dismisses the entire indictment but authorizes resubmission of the charge or charges to a grand jury, such authorization is, for purposes of this subdivision, deemed to constitute an order holding the defendant for the action of a grand jury with respect to such charge or charges. Such order must be accompanied by a securing order either releasing the defendant on his own recognizance or fixing bail or committing him to the custody of the sheriff pending resubmission of the case to the grand jury and the grand jury's disposition thereof. Such securing order remains in effect until the first to occur of any of the following:
1. (a) A statement to the court by the people that they do not intend to resubmit the case to a grand jury;
2. (b) Arraignment of the defendant upon an indictment or prosecutor's information filed as a result of resubmission of the case to a grand jury. Upon such arraignment, the arraigning court must issue a new securing order;
3. (c) The filing with the court of a grand jury dismissal of the case following resubmission thereof;
4. (d) The expiration of a period of forty-five days from the date of issuance of the order; provided that such period may, for good cause shown, be extended by the court to a designated subsequent date if such be necessary to accord the people reasonable opportunity to resubmit the case to a grand jury. Upon the termination of the effectiveness of the securing order pursuant to paragraph (a), (c) or (d), the court must immediately order that the defendant be discharged from custody if he is in the custody of the sheriff, or if he is at liberty on bail it must exonerate the bail. Although expiration of the period of time specified in paragraph (d) without any resubmission or grand jury disposition of the case terminates the effectiveness of the securing order, it does not terminate the effectiveness of the order authorizing resubmission.
