—[*1]Proceeding pursuant to CPLR article 78 in the nature of prohibition and mandamus, inter alia, to prohibit Damian Amodeo, a Judge of the Family Court, Dutchess County, from proceeding in a matter entitled Matter of Shockome v Shockome, pending in that court under docket Nos. V-5156-02, V-5157-02, V-5620-02, V-5621-02, and V-5362-02.

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 NY2d 564, 569 [1988]; see Matter of Rush v Mordue, 68 NY2d 348, 352 [1986]). Similarly, the extraordinary remedy of mandamus will lie only to compel the performance of a ministerial act and only when there exists a clear legal right to the relief sought (see Matter of Legal Aid Socy. of Sullivan County v Scheinman, 53 NY2d 12, 16 [1981]).

The petitioner has failed to demonstrate a clear legal right to the relief sought. Adams, J.P., Santucci, Lunn and Dillon, JJ., concur.
