New York Consolidated Laws, Criminal Procedure Law - CPL § 440.20 Motion to set aside sentence; by defendant

1. At any time after the entry of a judgment, the court in which the judgment was entered may, upon motion of the defendant, set aside the sentence upon the ground that it was unauthorized, illegally imposed or otherwise invalid as a matter of law. Where the judgment includes a sentence of death, the court may also set aside the sentence upon any of the grounds set forth in paragraph (b), (c), (f), (g) or (h) of subdivision one of section 440.10 as applied to a separate sentencing proceeding under section 400.27, provided, however, that to the extent the ground or grounds asserted include one or more of the aforesaid paragraphs of subdivision one of section 440.10, the court must also apply subdivisions two and three of section 440.10, other than paragraph (d) of subdivision two of such section, in determining the motion. In the event the court enters an order granting a motion to set aside a sentence of death under this section, the court must either direct a new sentencing proceeding in accordance with section 400.27 or, to the extent that the defendant cannot be resentenced to death consistent with the laws of this state or the constitution of this state or of the United States, resentence the defendant to life imprisonment without parole or to a sentence of imprisonment for the class A-I felony of murder in the first degree other than a sentence of life imprisonment without parole. Upon granting the motion upon any of the grounds set forth in the aforesaid paragraphs of subdivision one of section 440.10 and setting aside the sentence, the court must afford the people a reasonable period of time, which shall not be less than ten days, to determine whether to take an appeal from the order setting aside the sentence of death. The taking of an appeal by the people stays the effectiveness of that portion of the court's order that directs a new sentencing proceeding.

2. Notwithstanding the provisions of subdivision one, the court must deny such a motion when the ground or issue raised thereupon was previously determined on the merits upon an appeal from the judgment or sentence, unless since the time of such appellate determination there has been a retroactively effective change in the law controlling such issue.

3. Notwithstanding the provisions of subdivision one, the court may deny such a motion when the ground or issue raised thereupon was previously determined on the merits upon a prior motion or proceeding in a court of this state, other than an appeal from the judgment, or upon a prior motion or proceeding in a federal court, unless since the time of such determination there has been a retroactively effective change in the law controlling such issue. Despite such determination, however, the court in the interest of justice and for good cause shown, may in its discretion grant the motion if it is otherwise meritorious.

4. An order setting aside a sentence pursuant to this section does not affect the validity or status of the underlying conviction, and after entering such an order the court must resentence the defendant in accordance with the law.
