3.31A—Expert discovery.
(a)
The parties shall serve each other with a list of experts they intend to call as witnesses at the hearing not later than 1 day after the close of fact discovery, meaning the close of discovery except for depositions and other discovery permitted under § 3.24(a)(4), and discovery for purposes of authenticity and admissibility of exhibits. Complaint counsel shall serve the other parties with a report prepared by each of its expert witnesses not later than 14 days after the close of fact discovery. Each respondent shall serve each other party with a report prepared by each of its expert witnesses not later than 14 days after the deadline for service of complaint counsel's expert reports. Complaint counsel shall serve respondents with a list of any rebuttal expert witnesses and a rebuttal report prepared by each such witness not later than 10 days after the deadline for service of respondent's expert reports. Aside from any information required by paragraph (c), a rebuttal report shall be limited to rebuttal of matters set forth in a respondent's expert reports. If material outside the scope of fair rebuttal is presented, a respondent may file a motion not later than 5 days after the deadline for service of complaint counsel's rebuttal reports, seeking appropriate relief with the Administrative Law Judge, including striking all or part of the report, leave to submit a surrebuttal report by respondent's experts, or leave to call a surrebuttal witness and to submit a surrebuttal report by that witness.
(b)
No party may call an expert witness at the hearing unless he or she has been listed and has provided reports as required by this section. Each side will be limited to calling at the evidentiary hearing 5 expert witnesses, including any rebuttal or surrebuttal expert witnesses. A party may file a motion seeking leave to call additional expert witnesses due to extraordinary circumstances.
(c)
Each report shall be signed by the expert and contain a complete statement of all opinions to be expressed and the basis and reasons therefor; the data, materials, or other information considered by the witness in forming the opinions; any 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 10 years; the compensation to be paid for the study and testimony; and a listing of any other cases in which the witness has testified as an expert at trial or by deposition within the preceding 4 years. A rebuttal or surrebuttal report need not include any information already included in the initial report of the witness.
(d)
A party may depose any person who has been identified as an expert whose opinions may be presented at trial. Unless otherwise ordered by the Administrative Law Judge, a deposition of any expert witness shall be conducted after the disclosure of a report prepared by the witness in accordance with paragraph (a). Depositions of expert witnesses shall be completed not later than 65 days after the close of fact discovery. Upon motion, the Administrative Law Judge may order further discovery by other means, subject to such restrictions as to scope as the Administrative Law Judge may deem appropriate. A party, however, may not discover facts known or opinions held by an expert who has been retained or specially employed by another party in anticipation of litigation or preparation for hearing and who is not listed as a witness for the evidentiary hearing.
