§ Rule 1.508. Discovery of experts
Rule 1.508. Discovery of experts
1.508(1) Expert who is expected to be called as a witness.In addition to discovery provided pursuant to rule 1.516, discovery of facts known, mental impressions, and opinions held by an expert whom the other party expects to call as a witness at trial, otherwise discoverable under the provisions of rule 1.503(1) and acquired or developed in anticipation of litigation or for trial may be obtained as follows:
a. A party may through interrogatories require any other party to state the name and address of each person whom the other party expects to call as an expert witness at trial and to state, with reasonable particularity, all of the following:
(1) The subject matter on which the expert is expected to testify.
(2) The designated person's qualifications to testify as an expert on such subject.
(3) The mental impressions and opinions held by the expert and the facts known to the expert (regardless of when the factual information was acquired) which relate to, or form the basis of, the mental impressions and opinions held by the expert.
Nothing in this rule shall be construed to preclude a witness from testifying as to knowledge of the facts obtained by the witness prior to being retained as an expert or mental impressions or opinions formed by the witness which are based on such knowledge.
In the case of an expert retained in anticipation of litigation or for trial, answers to interrogatories asking for the qualifications of the person expected to testify as an expert, the mental impressions and opinions held by the expert, and the facts known to the expert shall be separately signed by the designated expert witness. If the party serving such interrogatories believes that the answers were required to be signed by the expert and they were not so signed, the party may object on that basis and move for an order compelling discovery. An objection based on the failure of such answers to be signed by the designated expert shall be asserted within 30 days of service of such answers, otherwise the objection is waived.
b. Discovery by other means is available without leave of court in lieu of or in addition to interrogatories:
(1) A party may take the deposition of any person identified by any other party as a person expected to be called as an expert witness at trial.
(2) A party may also obtain discovery of documents and tangible things including all tangible reports, physical models, compilations of data, and other material prepared by an expert or for an expert in anticipation of the expert's trial and deposition testimony. The disclosure of material prepared by an expert used for consultation is required even if it was prepared in anticipation of litigation or for trial when it forms a basis, either in whole or in part, of the opinions of an expert who is expected to be called as a witness.
(3) If the discoverable factual observations, tests, supporting data, calculations, photographs, or opinions of an expert who will be called as a witness have not been recorded and reduced to tangible form, the court may order these matters be reduced to tangible form and produced within a reasonable time before the date of trial.
1.508(2) Expert who is not expected to be called as a witness.The disclosure of the same information concerning an expert used for consultation and who is not expected to be called as a witness at trial is required if the expert's work product forms a basis, either in whole or in part, of the opinions of an expert who is expected to be called as a witness. Otherwise, a party may discover the identity of and facts known, or mental impressions 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 rule 1.516 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.
1.508(3) Duty to supplement discovery as to experts.If a party expects to call an expert witness when the identity or the substance of such expert witness' testimony has not been previously disclosed in response to an appropriate inquiry directly addressed to these matters, or when the substance of an expert's testimony has been updated, revised or changed since the response, such response must be supplemented to include the information described in rule 1.508(1)(a)(1) to (3), as soon as practicable, but in no event less than 30 days prior to the beginning of trial except on leave of court. If the identity of an expert witness and the information described in rule 1.508(1)(a)(1) to (3) are not disclosed or supplemented in compliance with this rule, the court in its discretion may exclude or limit the testimony of such expert, or make such orders in regard to the nondisclosure as are just.
1.508(4) Expert testimony at trial.To the extent that the facts known, or mental impressions and opinions held, by an expert have been developed in discovery proceedings under rule 1.508(1)(a) or 1.508(1)(b), the expert's direct testimony at trial may not be inconsistent with or go beyond the fair scope of the expert's testimony in the discovery proceedings as set forth in the expert's deposition, answer to interrogatories, separate report, or supplement thereto. However, the expert shall not be prevented from testifying as to facts or mental impressions and opinions on matters with respect to which the expert has not been interrogated in the discovery proceedings.
1.508(5) Court's discretion to compel disclosure of experts.The court has discretion to compel a party to make the determination and disclosure of whether an expert is expected to be called as a witness and shall do so to ensure that determination and the disclosures required by this rule occur within a reasonable and specific time before the date of trial. Upon motion, or at a discovery conference held pursuant to rule 1.507, or on its own initiative, the court may prescribe the sequence in which the parties make the determination and disclosures provided for under this rule.
1.508(6) Expert fees during discovery.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 rules 1.508(1)(b) and 1.508(2). With respect to discovery obtained under rule 1.508(1)(b), the court may require, and with respect to discovery obtained under rule 1.508(2), the court shall 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. Any fee which the court requires to be paid shall not exceed the expert's customary hourly or daily fee; and, in connection with a party's deposition of another party's expert, shall include the time reasonably and necessarily spent in connection with such deposition, including time spent in travel to and from the deposition, but excluding time spent in preparation.
