A. The court shall not order the production or inspection of any writing, or electronically stored information, obtained or prepared by the adverse party, his attorney, surety, indemnitor, or agent in anticipation of litigation or in preparation for trial unless satisfied that denial of production or inspection will unfairly prejudice the party seeking the production or inspection in preparing his claim or defense or will cause him undue hardship or injustice. Except as otherwise provided in Article 1425(E)(1), the court shall not order the production or inspection of any part of the writing, or electronically stored information, that reflects the mental impressions, conclusions, opinions, or theories of an attorney.B. A party may obtain without the required showing a statement concerning the action or its subject matter previously made by that party. Upon request, a person not a party may obtain without the required showing a statement concerning the action or its subject matter previously made by that person. If the request is refused, the person may move for a court order. The provisions of Article 1469(4)apply to the award of expenses incurred in relation to the motion. For purposes of this Paragraph, a statement previously made is a written statement signed or otherwise adopted or approved by the person making it, or a stenographic, mechanical, electronically stored, or other recording, or a transcription thereof, which is a substantially verbatim recital of an oral statement by the person making it and contemporaneously recorded.C. When a party withholds information otherwise discoverable under these rules by claiming that it is privileged or subject to protection as trial preparation material, the party shall make the claim expressly and shall describe the nature of the documents, communications, or things not produced or disclosed in a manner that, without revealing information itself privileged or protected, will enable other parties to assess the applicability of the privilege or protection.D. A disclosure of a communication or information covered by the attorney-client privilege or work product protection does not operate as a waiver if the disclosure is inadvertent and is made in connection with litigation or administrative proceedings, and if the person entitled to assert the privilege or work product protection took reasonably prompt measures, once the holder knew of the disclosure, to notify the receiving party of the inadvertence of the disclosure and the privilege asserted. Once notice is received, the receiving party shall either return or promptly safeguard the inadvertently disclosed material, but with the option of asserting a waiver. Even without notice of the inadvertent disclosure from the sending party, if it is clear that the material received is privileged and inadvertently produced, the receiving party shall either return or promptly safeguard the material, and shall notify the sending party of the material received, but with the option of asserting a waiver.
