2021 New York Laws CVP - Civil Practice Law and Rules Article 31 - Disclosure R3122 - Objection to Disclosure, Inspection or Examination; Compliance.

Rule   3122.  Objection  to  disclosure,  inspection  or  examination; compliance. (a) 1. Within twenty days of service of a notice or subpoena duces tecum under rule 3120 or section 3121, the party or person to whom the notice or subpoena duces tecum is directed, if that party or  person objects  to  the  disclosure,  inspection  or examination, shall serve a response which shall state with reasonable particularity the reasons for each objection. If objection is made to part of an item or category, the part shall be specified. The party seeking disclosure under rule 3120 or section 3121 may move for an order under rule 3124 or section 2308  with respect  to  any  objection to, or other failure to respond to or permit inspection  as  requested  by,  the  notice  or  subpoena  duces  tecum, respectively, or any part thereof.   2. A medical provider served with a subpoena duces tecum, other than a trial  subpoena  issued  by  a  court,  requesting  the  production of a patient's medical records pursuant to this  rule  need  not  respond  or object  to  the subpoena if the subpoena is not accompanied by a written authorization by  the  patient.  Any  subpoena  served  upon  a  medical provider  requesting  the  medical  records  of a patient shall state in conspicuous bold-faced type that  the  records  shall  not  be  provided unless  the  subpoena  is  accompanied by a written authorization by the patient, or the court has issued the subpoena or otherwise directed  the production of the documents.  (b)  Whenever a person is required pursuant to such a notice, subpoena duces tecum or order to produce documents for inspection, and where such person withholds one or more documents that  appear  to  be  within  the category  of  the documents required by the notice, subpoena duces tecum or order to be produced, such person shall  give  notice  to  the  party seeking  the production and inspection of the documents that one or more such documents are being withheld. This notice shall indicate the  legal ground  for  withholding  each  such  document,  and  shall  provide the following information  as  to  each  such  document,  unless  the  party withholding  the  document  states  that  divulgence of such information would cause disclosure of the allegedly privileged information: (1)  the type  of  document;  (2) the general subject matter of the document; (3) the date  of  the  document;  and  (4)  such  other  information  as  is sufficient to identify the document for a subpoena duces tecum.  (c)  Whenever a person is required pursuant to such notice or order to produce documents for inspection, that person shall produce them as they are kept in the regular course of business or shall organize  and  label them to correspond to the categories in the request.  (d) Unless the subpoena duces tecum directs the production of original documents  for  inspection and copying at the place where such items are usually maintained, it shall be sufficient for the  custodian  or  other qualified person to deliver complete and accurate copies of the items to be  produced.  The reasonable production expenses of a non-party witness shall be defrayed by the party seeking discovery.
