Judgment unanimously reversed, on the law, and petition dismissed. Memorandum: Petitioner waived his right to challenge the legality of a Superintendent's proceeding by refusing to attend the hearing (Matter of Payne v Smith, 97 A.D.2d 960; see also, Matter of Morrison v Coughlin, 101 A.D.2d 943, 944, lv denied 63 N.Y.2d 605; People ex rel. Morgan v La Vallee, 49 A.D.2d 652, lv. denied 37 N.Y.2d 710). In any event, petitioner's claim that a written misbehavior report did not constitute substantial evidence in support of the determination is without merit (see, Matter of Semper v Smith, 66 N.Y.2d 130).
