¶1—Proceeding pursuant to CPLR article 78 in the nature of prohibition, inter alia, to prohibit the respondent from trying the petitioner under Queens County Indictment No. 5867/94, until a trial under Kings County Indictment No. 14860/94 has been commenced and concluded on the ground that trial of the Queens County indictment before that of the Kings County indictment will violate the defendant’s constitutional right against self-incrimination.
¶2Upon the petition and papers filed in support of the proceeding, and the papers filed in opposition thereto, it is
¶3Adjudged that the petition is denied and the proceeding is dismissed, without costs or disbursements.
¶4"Because of its extraordinary nature, prohibition is available *713only 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 NY2d 564, 569; see, Matter of Rush v Mordue, 68 NY2d 348, 352). The petitioner here has failed to demonstrate a clear legal right to the relief sought. Bracken, J. P., Miller, Altman and Florio, JJ., concur.
