Matter of Menkes v Molia, 2019 NY Slip Op 06493 [2d Dept. 2019]
The extraordinary remedy of mandamus will lie only to compel the performance of a ministerial act, and only where 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). “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; see Matter of Rush v Mordue , 68 NY2d 348, 352). The petitioner has failed to demonstrate a clear legal right to the relief sought.
