TOM SCHANZLE-HASKINS, Magistrate Judge.
This matter comes before the Court on Plaintiffs' Motion to Compel Production of Communications between Defendant's Testifying Experts and their Staff (d/e 177) (Motion). Plaintiffs ask the Court to compel Defendant Illinois Power Resources Generating, LLC (Illinois Power or IPRG) "to produce documents reflecting communications each of its testifying experts had with his/her employees, staff, and /or assistants regarding his/her study or testimony for the remedy phase of this case (hereafter expert-staff communications)." For the reasons set forth below, the Motion is ALLOWED in part and DENIED in part.
The District Court found Illinois Power liable for violations of the Clean Air Act because the smoke stack emissions from the Edwards Power Plant (Plant) exceeded the limits on opacity caused by particulate material in the emissions.
On May 15, 2018, the Plaintiffs served notices of depositions duces tecum for each of Illinois Power's testifying experts (Notices). The Notices directed the experts to produce documents, including all communications with anyone other than Illinois Power's attorneys concerning the expert's opinions prepared for this case, which would include expert-staff communications.
The Federal Rules of Civil Procedure prescribe the limits of discovery from testifying experts:
Fed. R. Civ. P. 26(b)(4)(A)-(C) (emphasis in the original). Rules 26(b)(4)(B) and (b)(4)(C) provide protection from discovery under the work product privilege embodied in Rule 26(b)(3) for certain information: drafts of reports and communications with counsel subject to the three exceptions in Rule 26(b)(4)(i)-(iii). Rule 26(b)(3) protects documents covered by the work product privilege from discovery unless the requesting party shows a substantial need for the information to prepare its case and cannot, without undue hardship, obtain equivalent information by other means. Fed. R. Civ. P. 26(b)(3)(A).
Rule 26(b) was amended in 2010 to add work product privilege protections of draft reports and testifying expert communications with attorneys. The change allows attorneys to interact with experts more freely in order to prepare the case. Prior to the change, all documents provided to testifying experts were discoverable, even documents that would have otherwise been protected as attorney work product.
The 2010 Amendment does not provide a blanket work product privilege for all documents generated by testifying experts. Rule 26(b)(4)(B)-(C) still allows the opposing side to discover sufficient information to prepare its case:
The Advisory Committee further states that the scope of documents covered as drafts or attorney communications "do not impede discovery about the opinions to be offered by the expert or the development, foundation, or basis of those opinions." For example, that notes of results from relevant tests conducted by the expert's staff members would not be protected. Also, "[I]nquiry about communications the expert had with anyone other than the party's counsel about the opinions expressed is unaffected by the rule."
In light of the language of Rule 26(b)(4) and the Advisory Committee Notes, the Court concludes that expert-staff communications sought by Plaintiffs in this case should not be subject to a blanket work product privilege. The expert does not get blanket protection by the rule, so neither should the staff member. The expert must produce notes of test results and other such documentation that underlies his or her expert opinions. The staff member's communication of such notes to the expert should not convert those notes into work product. The expert's communication with third parties are not protected. The expert's staff member's communications of the substance of such third-party conversations to the expert should not convert the communications into work product.
Rather, the Rule 26(b)(4)(B)-(C) privilege extends to expert-staff communications that constitute drafts of the expert report, or portions thereof; and expert-staff communications that would reveal the mental impressions, conclusions, or legal theories of the party's attorneys that do not fit into the three exceptions set forth in Rule 26(b)(4)(C)(i)-(iii). The language of the Rule protects drafts and attorney-expert communications from discovery to allow attorneys to consult with testifying experts. The purpose of the rule is to allow effective communication and consultation with the expert and to protect the mental impressions, conclusions, or legal theories of the party's attorneys. The Advisory Committee Notes state that staff communications with attorneys should also be protected. The Advisory Committee thereby acknowledges that the expert and the attorney both need to communicate in a confidential manner with the expert's staff.
One Court decided that the testifying expert work product privilege in Rule 26(b)(4) covers all expert-staff communications.
Illinois Power is directed to produce responsive, non-privileged documents containing expert-staff communications with respect to Illinois Power experts Robert M. Lewis and Tony Schroeder by July 31, 2018, in a manner consistent with this Opinion. Illinois Power must also produce a privilege log in which Illinois Power sets forth the nature of each withheld document in a manner that, without revealing information itself privileged, will enable the parties and the Court to assess the claim of privilege for each withheld document.
Illinois Power is further directed to follow this Opinion in its responses to notices of depositions duces tecum for its other testifying expert witnesses Dr. Anne Smith, Dr. Lucy Fraiser, Mr. Thomas Keeler, and Mr. Ed Cichanowicz. If Illinois Power has already responded to any of the notices of depositions duces tecum for any of these testifying experts, Illinois Power is directed to submit a revised response that follows this Opinion by July 31, 2018. Illinois Power may state its objections in the responses (or restate objections in any revised responses) to preserve those objections, but must then comply with this Opinion.
THEREFORE, IT IS ORDERED that Plaintiffs' Motion to Compel Production of Communications between Defendant's Testifying Experts and their Staff (d/e 177) is ALLOWED in part and DENIED in part.
