Ordered that the order is affirmed, without costs or disbursements.
CPLR 3101 (a) requires "full disclosure of all matter material and necessary in the prosecution or defense of an action." "The phrase `material and necessary' should be `interpreted liberally to require disclosure, upon request, of any facts bearing on the controversy which will assist preparation for trial by sharpening the issues and reducing delay and prolixity. The test is one of usefulness and reason'" ( Friel v Papa, 56 AD3d 607, 608, quoting Allen v Crowell-Collier Publ. Co., 21 NY2d 403, 406). A party, however, does not have the right to "uncontrolled and unfettered disclosure" ( Gilman Ciocia, Inc. v Walsh, 45 AD3d 531; see Barouh Eaton Allen Corp. v International Bus. Machs. Corp., 76 AD2d 873). "`It is incumbent on the party seeking disclosure to demonstrate that the method of discovery sought will result in the disclosure of relevant evidence or is reasonably calculated to lead to the discovery of information bearing on the claims'" ( Vyas v Campbell, 4 AD3d 417, 418, quoting Crazytown Furniture v Brooklyn Union Gas Co., 150 AD2d 420, 421).
"The Supreme Court has broad discretion in the supervision of discovery, and its determinations should not be disturbed on appeal unless improvidently made" ( Casabona v Huntington Union Free School Dist., 29 AD3d 723, 723; see Andon v 302-304 Mott St. Assoc., 94 NY2d 740, 746; Milbrandt Co., Inc. v Griffin, 19 AD3d 663; Provident Life Cas. Ins. Co. v Brittenham, 284 AD2d 518). Here, the Supreme Court providently exercised its discretion in concluding, inter alia, that the additional discovery sought by the appellants was neither material nor necessary to the prosecution or defense of any claim ( see CPLR 3101 [a]; Casabona v Huntington Union Free School Dist., 29 AD3d 723; Vyas v Campbell, 4 AD3d 417; Palermo Mason Constr. v Aark Holding Corp., 300 AD2d 460).
