N.Y. Const. art. VI, § 30: Regulation of jurisdiction, practice and procedure of the courts

§ 30. The legislature shall have the same power to alter and regulate

the jurisdiction and proceedings in law and in equity that it has

heretofore exercised. The legislature may, on such terms as it shall

provide and subject to subsequent modification, delegate, in whole or in

part, to a court, including the appellate division of the supreme court,

or to the chief administrator of the courts, any power possessed by the

legislature to regulate practice and procedure in the courts. The chief

administrator of the courts shall exercise any such power delegated to

him or her with the advice and consent of the administrative board of

the courts. Nothing herein contained shall prevent the adoption of

regulations by individual courts consistent with the general practice

and procedure as provided by statute or general rules.
