Article 2. Demand For Exchange Of Expert Witness Information
2034.210. After the setting of the initial trial date for the action, any party may obtain discovery by demanding that all parties simultaneously exchange information concerning each other's expert trial witnesses to the following extent: (a) Any party may demand a mutual and simultaneous exchange by all parties of a list containing the name and address of any natural person, including one who is a party, whose oral or deposition testimony in the form of an expert opinion any party expects to offer in evidence at the trial. (b) If any expert designated by a party under subdivision (a) is a party or an employee of a party, or has been retained by a party for the purpose of forming and expressing an opinion in anticipation of the litigation or in preparation for the trial of the action, the designation of that witness shall include or be accompanied by an expert witness declaration under Section 2034.260. (c) Any party may also include a demand for the mutual and simultaneous production for inspection and copying of all discoverable reports and writings, if any, made by any expert described in subdivision (b) in the course of preparing that expert's opinion. 2034.220. Any party may make a demand for an exchange of information concerning expert trial witnesses without leave of court. A party shall make this demand no later than the 10th day after the initial trial date has been set, or 70 days before that trial date, whichever is closer to the trial date. 2034.230. (a) A demand for an exchange of information concerning expert trial witnesses shall be in writing and shall identify, below the title of the case, the party making the demand. The demand shall state that it is being made under this chapter. (b) The demand shall specify the date for the exchange of lists of expert trial witnesses, expert witness declarations, and any demanded production of writings. The specified date of exchange shall be 50 days before the initial trial date, or 20 days after service of the demand, whichever is closer to the trial date, unless the court, on motion and a showing of good cause, orders an earlier or later date of exchange. 2034.240. The party demanding an exchange of information concerning expert trial witnesses shall serve the demand on all parties who have appeared in the action. 2034.250. (a) A party who has been served with a demand to exchange information concerning expert trial witnesses may promptly move for a protective order. This motion shall be accompanied by a meet and confer declaration under Section 2016.040. (b) The court, for good cause shown, may make any order that justice requires to protect any party from unwarranted annoyance, embarrassment, oppression, or undue burden and expense. The protective order may include, but is not limited to, one or more of the following directions: (1) That the demand be quashed because it was not timely served. (2) That the date of exchange be earlier or later than that specified in the demand. (3) That the exchange be made only on specified terms and conditions. (4) That the production and exchange of any reports and writings of experts be made at a different place or at a different time than specified in the demand. (5) That some or all of the parties be divided into sides on the basis of their identity of interest in the issues in the action, and that the designation of any experts as described in subdivision (b) of Section 2034.210 be made by any side so created. (6) That a party or a side reduce the list of employed or retained experts designated by that party or side under subdivision (b) of Section 2034.210. (c) If the motion for a protective order is denied in whole or in part, the court may order that the parties against whom the motion is brought, provide or permit the discovery against which the protection was sought on those terms and conditions that are just. (d) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion for a protective order under this section, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust. 2034.260. (a) All parties who have appeared in the action shall exchange information concerning expert witnesses in writing on or before the date of exchange specified in the demand. The exchange of information may occur at a meeting of the attorneys for the parties involved or by a mailing on or before the date of exchange. (b) The exchange of expert witness information shall include either of the following: (1) A list setting forth the name and address of any person whose expert opinion that party expects to offer in evidence at the trial. (2) A statement that the party does not presently intend to offer the testimony of any expert witness. (c) If any witness on the list is an expert as described in subdivision (b) of Section 2034.210, the exchange shall also include or be accompanied by an expert witness declaration signed only by the attorney for the party designating the expert, or by that party if that party has no attorney. This declaration shall be under penalty of perjury and shall contain: (1) A brief narrative statement of the qualifications of each expert. (2) A brief narrative statement of the general substance of the testimony that the expert is expected to give. (3) A representation that the expert has agreed to testify at the trial. (4) A representation that the expert will be sufficiently familiar with the pending action to submit to a meaningful oral deposition concerning the specific testimony, including any opinion and its basis, that the expert is expected to give at trial. (5) A statement of the expert's hourly and daily fee for providing deposition testimony and for consulting with the retaining attorney. 2034.270. If a demand for an exchange of information concerning expert trial witnesses includes a demand for production of reports and writings as described in subdivision (c) of Section 2034.210, all parties shall produce and exchange, at the place and on the date specified in the demand, all discoverable reports and writings, if any, made by any designated expert described in subdivision (b) of Section 2034.210. 2034.280. (a) Within 20 days after the exchange described in Section 2034.260, any party who engaged in the exchange may submit a supplemental expert witness list containing the name and address of any experts who will express an opinion on a subject to be covered by an expert designated by an adverse party to the exchange, if the party supplementing an expert witness list has not previously retained an expert to testify on that subject. (b) This supplemental list shall be accompanied by an expert witness declaration under subdivision (c) of Section 2034.260 concerning those additional experts, and by all discoverable reports and writings, if any, made by those additional experts. (c) The party shall also make those experts available immediately for a deposition under Article 3 (commencing with Section 2034.410), which deposition may be taken even though the time limit for discovery under Chapter 8 (commencing with Section 2024.010) has expired. 2034.290. (a) A demand for an exchange of information concerning expert trial witnesses, and any expert witness lists and declarations exchanged shall not be filed with the court. (b) The party demanding the exchange shall retain both the original of the demand, with the original proof of service affixed, and the original of all expert witness lists and declarations exchanged in response to the demand until six months after final disposition of the action. At that time, all originals may be destroyed unless the court, on motion of any party and for good cause shown, orders that the originals be preserved for a longer period. (c) Notwithstanding subdivisions (a) and (b), a demand for exchange of information concerning expert trial witnesses, and all expert witness lists and declarations exchanged in response to it, shall be lodged with the court when their contents become relevant to an issue in any pending matter in the action. 2034.300. Except as provided in Section 2034.310 and in Articles 4 (commencing with Section 2034.610) and 5 (commencing with Section 2034.710), on objection of any party who has made a complete and timely compliance with Section 2034.260, the trial court shall exclude from evidence the expert opinion of any witness that is offered by any party who has unreasonably failed to do any of the following: (a) List that witness as an expert under Section 2034.260. (b) Submit an expert witness declaration. (c) Produce reports and writings of expert witnesses under Section 2034.270. (d) Make that expert available for a deposition under Article 3 (commencing with Section 2034.410). 2034.310. A party may call as a witness at trial an expert not previously designated by that party if either of the following conditions is satisfied: (a) That expert has been designated by another party and has thereafter been deposed under Article 3 (commencing with Section 2034.410). (b) That expert is called as a witness to impeach the testimony of an expert witness offered by any other party at the trial. This impeachment may include testimony to the falsity or nonexistence of any fact used as the foundation for any opinion by any other party's expert witness, but may not include testimony that contradicts the opinion.
