Adjudged that the petition is denied and the proceeding is dismissed, without costs or disbursements.
"Because of its extraordinary nature, prohibition is available only where there is a clear legal right, and then only when a court — in cases where judicial authority is challenged — acts or threatens to act either without jurisdiction or in excess of its authorized powers" (Matter of Holtzman v. Goldman, 71 N.Y.2d 564, 569; see, Matter of Rush v. Mordue, 68 N.Y.2d 348, 352). The petitioner here has failed to demonstrate a clear legal right to the relief sought. Bracken, J.P., Rosenblatt, Santucci and Joy, JJ., concur.
