(a) Parties shall strictly comply with discovery obligations by the dates set forth in all case scheduling orders. Applications for extension of a discovery deadline shall be made as soon as practicable and prior to the expiration of such deadline. Non-compliance with such an order may result in the imposition of an appropriate sanction against that party or for other relief pursuant to CPLR 3126.

(b) If a party seeks documents from an adverse party as a condition precedent to a deposition of such party and the documents are not produced by the date fixed, the party seeking disclosure may ask the court to preclude the non-producing party from introducing such demanded documents at trial.
