N.Y. Exec. Law § 19
Upon motion duly made therefor, the judgment of conviction must be set aside and the indictment, information or complaint dismissed by the court in which the defendant was convicted, in a case where the defendant shall receive a pardon from the governor stating that such pardon is issued on the ground of innocence of the crime for which he was convicted and further stating that such finding of innocence is based upon evidence discovered after the judgment of conviction was rendered and after the time within which to make a motion for a new trial on newly discovered evidence had expired. Such setting aside of a judgment of conviction and dismissal of an indictment, information or complaint against a defendant shall place the defendant in the same position as if the indictment, information or complaint had been dismissed at the conclusion of the trial by the court because of the failure to establish the defendant's guilt beyond a reasonable doubt.
