New York Consolidated Laws, Criminal Procedure Law - CPL § 470.50 Reargument of appeal; motion and criteria for

1. After its determination of an appeal taken pursuant to article four hundred fifty, an appellate court, in the interest of justice and for good cause shown, may in its discretion, upon motion of a party adversely affected by its determination, or upon its own motion, order a reargument or reconsideration of the appeal. Upon such an order the court may either direct further oral argument by the parties or confine its reconsideration to re-examination of the issues as previously argued or submitted upon the appeal proper. Upon ordering a reargument or reconsideration of an appeal, the court must again determine the appeal pursuant to the provisions of this article.

2. The court of appeals may promulgate rules limiting the time within which a motion for reargument of appeals determined by such court may be made, and the appellate division of each department may similarly promulgate such rules with respect to appeals determined by such appellate division and appeals determined by the other intermediate appellate courts located within such department. In the absence of any such rule of limitation, a motion for reargument may be made at any time.
