Since defendant filed his motion in Supreme Court, Criminal Term and the motion was related to his completed criminal action (a conviction in 1989), the order arose out of a criminal proceeding ( see CPL 1.20 [b]), and "no appeal lies from an order arising out of a criminal proceeding absent specific statutory authorization" ( People v Santos, 64 NY2d 702, 704; see also People v Stevens, 91 NY2d 270, 277). Nothing in CPL article 450 authorizes an appeal from an order denying a motion for a subpoena duces tecum.
