Document:
A. A party may through interrogatories or by deposition require any other party to identify each person who may be used at trial to present evidence under Articles 702 through 705 of the Louisiana Code of Evidence.
B. Upon contradictory motion of any party or on the court's own motion, an order may be entered requiring that each party that has retained or specially employed a person to provide expert testimony in the case or whose duties as an employee of the party regularly involve giving expert testimony provide a written report prepared and signed by the witness. The report shall contain a complete statement of all opinions to be expressed and the basis and reasons therefor and the data or other information considered by the witness in forming the opinions. The parties, upon agreement, or if ordered by the court, shall include in the report any or all of the following: exhibits to be used as a summary of or support for the opinions; the qualifications of the witness, including a list of all publications authored by the witness within the preceding ten years; the compensation to be paid for the study and testimony; a listing of any other cases in which the witness has testified as an expert at trial or by deposition within the preceding four years.
C. If the court orders the disclosures of Paragraph B of this Article, they shall be made at the times and in the sequence directed by the court. In the absence of directions from the court or stipulation by the parties, the disclosures ordered pursuant to Paragraph B of this Article shall be made at least ninety days before the trial date or, if the evidence is intended solely to contradict or rebut evidence on the same subject matter identified by another party under Paragraph B of this Article, within thirty days after the disclosure made by the other party. The parties shall supplement these disclosures when required by Article 1428.
D.(1) Except as otherwise provided in Paragraph E of this Article, a party may, through interrogatories, deposition, and a request for documents and tangible things, discover facts known or opinions held by any person who has been identified as an expert whose opinions may be presented at trial. If a report from the expert is required under Paragraph B, the deposition shall not be conducted until after the report is provided.
(2) A party may, through interrogatories or by deposition, discover facts known by and opinions held by an expert who has been retained or specially employed by another party in anticipation of litigation or preparation for trial and who is not expected to be called as a witness at trial, only as provided in Article 1465 or upon a showing of exceptional circumstances under which it is impracticable for the party seeking discovery to obtain facts or opinions on the same subject by other means.
(3) Unless manifest injustice would result, the court shall require that the party seeking discovery pay the expert a reasonable fee for time spent in responding to discovery under this Paragraph; and with respect to discovery obtained under Subparagraph (2) of this Paragraph, the court shall also require the party seeking discovery to pay the other party a fair portion of the fees and expenses reasonably incurred by the latter party in obtaining facts and opinions from the expert.
E.(1) The expert's drafts of a report required under Paragraph B of this Article, and communications, including notes and electronically stored information or portions thereof that would reveal the mental impressions, opinions, or trial strategy of the attorney for the party who has retained the expert to testify, shall not be discoverable except, in either case, on a showing of exceptional circumstances under which it is impractical for the party seeking discovery to obtain facts or opinions on the same subject by other means.
(2) Nothing in this Article shall preclude opposing counsel from obtaining any facts or data the expert is relying on in forming his opinion, including that coming from counsel, or from otherwise inquiring fully of an expert into what facts or data the expert considered, whether the expert considered alternative approaches, or into the validity of the expert's opinions.
