2010 Expert Witness Rule Amendments

Gregory P. Joseph*

Effective December 1, 2010, Federal Rules of Civil Procedure 26(a)(2) and (b)(4) are substantially amended. These amendments govern disclosure of expert opinion.

Three Principal Changes. The principal practice changes are:

  1. Communications between counsel and retained experts are generally protected from disclosure or discovery.
  2. Draft expert reports are no longer discoverable.
  3. Counsel must summarize in writing the facts and opinions to be attested to by experts who are not required to file expert reports.

Counsel/Expert Communications

The 1993 amendments to Rule 26(a)(2)(B) were construed as opening the door to discovery of all communications between counsel and expert relating to the subject matter of the litigation, for two reasons. First, Rule 26(a)(2)(B) mandated that the retained expert’s report contain all of “the data or other information considered by the witness in forming” his or her opinion. “Other information” was interpreted to include everything communicated by counsel to expert. See, e.g., Reg’l Airport Auth. v. LFG, LLC, 460 F.3d 697, 716 (6th Cir. 2006).

Second, the 1993 Advisory Committee Note observed that: “Given the obligation of disclosure, litigants should no longer be able to argue the materials furnished to their experts to be used in forming their opinions are protected from disclosure when such persons are testifying or being deposed.” Work product protection, to the extent it previously existed, vanished.

The 2010 amendments close the door to almost all discovery between communications between counsel and retained experts. First, Rule 26(a)(2)(B)(ii) is amended to eliminate the phrase “data or other information” and substitute: “the facts or data or other information considered by the witness in forming them [the opinions].” The accompanying Committee Note reflects that this amendment “is intended to alter the outcome in cases that have relied on the 1993 formulation in requiring disclosure of all attorney-expert communications and draft reports.” Because this is an amendment to the report requirement, by definition Rule 26(a)(2)(B)(ii) applies only to counsel’s communications with experts who must file a Rule 26(a)(2)(B) report.

Second, Rule 26(b)(4)(C) is amended to confer work product protection (which is set forth in Rule 26(b)(3)) on most communications between attorneys and retained experts:

(C) Trial-Preparation Protection for Communications Between a Party’s Attorney and Expert Witnesses. Rules 26(b)(3)(A) and (B) protect communications between the party’s attorney and any witness required to provide a report under Rule 26(a)(2)(B), regardless of the form of the communications, except to the extent that the communications:

  1. relate to compensation for the expert’s study or testimony;

  2. identify facts or data that the party’s attorney provided to the expert and that the expert considered in forming the opinions to be expressed; or

  3. identify assumptions that the party’s attorney provided to the expert and that the expert relied on in forming the opinions to be expressed.

Retained vs. Unretained Experts. Note that this provision (like the amendment to Rule 26(a)(2)(B)(ii)) applies only to experts from whom Rule 26(a)(2)(B) reports are required — retained experts or party employees who regularly provide expert testimony on behalf of their employer. Amended Rule 26(b)(4)(C) does not apply to communications between lawyers and witnesses who provide expert testimony but are not required to furnish a report (non-reporting experts) because they were not “retained or specially employed to provide expert testimony” or their duties as party employees do not “regularly involve giving expert testimony.”

Exceptions. With this scope limitation in mind, the only unprotected communications between attorneys and reporting experts are those relating to (i) compensation, (ii) facts or data provided by counsel and considered by the expert, and (iii) assumptions provided by counsel relied on by the expert.

Compensation. The Committee Note clarifies that “compensation” includes potential additional work for the expert, as well as compensation for work done by assistants, associates and affiliated organizations. Presumably all other financial incentives are freely discoverable, as “[t]he objective is to permit full inquiry into such potential sources of bias.”

Facts vs. Assumptions: “Considered” vs. “Relied Upon.” There is a world of difference between facts or data “considered” (Rule 26(a)(2)(B)(i)) and assumption “relied on” (Rule 26(a)(2)(B)(ii)), as those quoted words have been interpreted in the jurisprudence of Rule 26(a)(2). “Considered” is the word used in the 1993 version of Rule 26(a)(2)(B)(ii), and, together with the now-stricken “other information,” it was read as requiring disclosure of all communications between attorney and expert “related to the subject matter of the litigation.” See Karn v. Ingersoll Rand, 168 F.R.D. 633, 639 (N.D. Ind. 1996) (noting that the Advisory Committee in 1993 substituted “considered” for the more restrictive “relied upon” in an earlier draft of rule 26(a)(2)(B)).

Under the 2010 amendment, “considered” is confined to “facts or data” provided by counsel, but does not apply to counsel-supplied “assumptions” (those must be “relied on”). Therefore, all facts or data communicated by counsel relating to the subject matter of the litigation must be “identif[ied].” The Committee Note stresses that “the refocus of disclosure on ‘facts or data’ is meant to limit disclosure to material of a factual nature by excluding theories or mental impressions of counsel.”[Footnote 1] The Committee Note also emphasizes that (1) “the intention is that ‘facts or data’ be interpreted broadly to require disclosure of any material considered by the expert, from whatever source, that contains factual ingredients,” and (2) the facts or data need only be “identif[ied]” — “further communications about the potential relevance of the facts or data are protected.”

In contrast, assumptions furnished by counsel are discoverable only if they are actually relied on by the expert in forming his or her opinion.

“Regardless of the Form of the Communications.” One of the textual problems with Rule 26(b)(3) is that it affords work product protection only to “documents and tangible things.” Work product takes many forms that are non-documentary and intangible, including discussions. For these, litigants must rely on common law protection, derived from Hickman v. Taylor, 329 U.S. 495, 510-11 (1947). See 6 MOORE'S FEDERAL PRACTICE § 26.70[2][c] (3d ed. 2010). Rule 26(b)(4)(C) explicitly covers the waterfront, extending to all forms of communication.

“A Party’s Attorney.” Parties often have many attorneys, including in-house counsel; outside general counsel; and counsel in other cases dealing with the same or similar subject matters. The Committee Note to Rule 26(b)(4)(C) stresses that the work product protection it recognizes “should be applied in a realistic manner,” generally extending to these lawyers, each of whom is “the party’s attorney,” albeit not necessarily before the court, and observes that “[o]ther situations may also justify a pragmatic application of the ‘party’s attorney’ concept.”

Draft Expert Reports

The previously-discussed change to Rule 26(a)(2)(B)(ii) (“the facts or data or other information considered by the witness”) is one of the two amendments intended to protect draft expert reports, as reflected in the Committee Note excerpt quoted above. The second, direct approach is new Rule 26(b)(4)(B), which provides:

(B) Trial-Preparation Protection for Draft Reports or Disclosures. Rules 26(b)(3)(A) and (B) protect drafts of any report or disclosure required under Rule 26(a)(2), regardless of the form in which the draft is recorded.

Only “Recorded” Drafts Covered. The text of Rule 26(b)(4)(B) and the Advisory Committee Note were amended after comments were received on the publication-version of this proposal to add that the drafts covered by this provision must be “recorded.” Oral communications with retained experts are separately cloaked with work product protection by Rule 26(b)(4)(C). Therefore, this revision should be construed as providing no protection for unrecorded oral communications with unretained experts.

Non-Reporting Experts. Under Rule 26(b)(4)(B), work product protection extends to written or otherwise-“recorded” drafts of the new Rule 26(a)(2)(C) disclosures (discussed below), which summarize the testimony of experts who are not obliged to file a 26(a)(2)(B) report. Query whether audio recording one’s conversations with a non-reporting expert concerning his or her opinion suffices the conversations within the work product protection afforded by Rule 26(b)(4)(B), the issue being whether that conversation constitutes a “draft.”

Impact on Discovery and Cross-Examination

The Committee Note discusses the breadth of work product protection afforded by Rules 26(b)(4)(B) and (C):

  • Depositions. The protection afforded by Rule 26(b)(4)(B) (draft reports) and 26(b)(4)(C) (attorney communications with retained experts) extends to depositions and “all forms of discovery.”

  • No Other Limit on Exploring Foundation. Neither Rule 26(b)(4)(B) or (C) otherwise “impede[s] discovery about the opinions to be offered by the expert or the development, foundation, or basis of those opinions.”

  • Substantial Need Required for Additional Discovery. The Advisory Committee Note adds that “discovery regarding attorney-expert communications on subjects outside the three exceptions in Rule 26(b)(4)(C), or regarding draft expert reports or disclosures, is permitted only in limited circumstances and by court order.” That order requires a showing of substantial need pursuant to Rule 26(b)(3)(A)(ii).

Rules Enabling Act Issues

Rules 26(b)(4)(B) and (C) by their terms confer work product protection, as codified in Rule 26(b)(3)(A) and (B), on draft expert reports and communications between counsel and reporting experts. This may seem odd, given that 28 U.S.C. § 2074(b) provides: “Any ... rule [of procedure or evidence] creating, abolishing, or modifying an evidentiary privilege shall have no force or effect unless approved by Act of Congress.” How, then, can a Rule of Civil Procedure adopted after enactment of these statutes in 1988 affect work product protection absent an affirmative act of Congress? Of course, the same issue was posed by the 1993 amendment to Rule 26(a)(2)(B), which appeared to strip privilege and work product protection from communications between attorneys and experts.[Footnote 2] This issue was never the subject of a reported decision (it does not appear that it was ever litigated).

Perhaps work product protection is not “an evidentiary privilege.” Perhaps the Rules are simply reverting to the pre-1993 legal landscape. Perhaps it is simply a deferral to the common law. Perhaps this provision, too, will never be litigated.

The common law of work product protection may affect, in practice, the textual differences in scope of Rules 26(b)(4)(B) and (C). Rule 26(b)(4)(B) applies to drafts of all expert reports and disclosures, while 26(b)(4)(C) extends work product protection to counsel’s communications only with reporting (not non-reporting) experts. Just because Rule 26(b)(4)(C) does not extend work product protection to all conversations with non-reporting experts does not necessarily mean that those conversations are unprotected. The Committee Note alludes to the possibility that these communications may be protected by “privilege or independent development of the work-product doctrine.” Since the Rules cannot create, abolish, or modify an evidentiary privilege under § 2074(b), this will be left to case law development.

Privilege Implications

Rules 26(b)(4)(B) and (C) address only work product protection, but they have potential attorney-client privilege repercussions. One effect of the 1993 amendments to Rule 26(a)(2)(B) was to make waiver an unavoidable cost of putting an expert forward to testify. Because communications between counsel and expert, and draft expert reports, were subject to disclosure and discovery, no plausible expectation of confidentiality could be asserted. Therefore, no viable claim of attorney-client privilege could be asserted with respect to those communications.

The amendments to Rules 26(b)(4)(B) and (C), however, reverse the expectation. It is true that, under Rules 26(b)(3)(A) and (B), an opposing party may obtain disclosure of work product on a showing of “substantial need” and an inability, “without undue hardship, [to] obtain their substantial equivalent by other means.” The Committee Note that accompanies the amendments contemplates that: “It will be rare for a party to be able to make such a showing given the broad disclosure and discovery otherwise allowed regarding the expert’s testimony.” Certain communications between attorney and expert may again be subject to a reasonable expectation of privacy and fall within the umbra of attorney-client privilege.

Disclosures for Non-Reporting Experts

Prior to the 2010 amendments, there were no mandatory disclosure requirements for non-reporting experts. The report requirement of Rule 26(a)(2)(B) was confined to any witness “retained or specially employed to provide expert testimony in the case or one whose duties as the party’s employee regularly involve giving expert testimony.” If anyone else expected to provide expert testimony in a case — a treating physician, an employee whose duties did not regularly involve giving expert testimony, a third party witness — no report was required. Instead, under Rule 26(a)(2)(A), the proponent of the testimony was simply required to “disclose to the other parties the identity of any witness it may use at trial to present evidence under Federal Rule of Evidence 702, 703, or 705.” The absence of any required disclosures for non-reporting experts lent itself to the prospect of trial by ambush, and to district judges occasionally imposing disclosure requirements on an ad hoc basis.

2010 Rule 26(a)(2)(C) mandates counsel-prepared disclosures for non-reporting experts:

(C) Witnesses Who Do Not Provide a Written Report. Unless otherwise stipulated or ordered by the court, if the witness is not required to provide a written report, this disclosure must state:

  1. the subject matter on which the witness is expected to present evidence under Federal Rule of Evidence 702, 703, or 705; and

  2. a summary of the facts and opinions to which the witness is expected to testify.

This requirement is similar in substance to the pre-1993 version of Rule 26(b)(4)(A), which permitted expert discovery primarily by means of interrogatories requiring each party “to identify each person whom the ... party expects to call as an expert witness at the trial, to state the subject matter on which the expert is expected to testify and a summary of the grounds for each opinion.”

Timing of Disclosure and Rebuttal. There is no set time for the Rule 26(a)(2)(C) disclosure, except “at the times and in the sequence that the court orders,” under Rule 26(a)(2)(D). Pretrial orders should be amended to cover the timing of these reports. Absent that, these disclosures may be made at any time up to 90 days before trial (id.).

Identical timing for 26(a)(2)(A) summaries and 26(a)(2)(B) reports is implicit in 26(a)(2)(D)(ii), which provides that: “if the evidence is intended solely to contradict or rebut evidence on the same subject matter identified by another party under Rule 26(a)(2)(B) or (C), within 30 days after the other party’s disclosure.” But the reality is that the timing of 26(a)(2)(B) reports is governed by pretrial orders, not the 26(a)(2)(D)(ii) default. It will take a period of time for pretrial orders uniformly to cover 26(a)(2)(A) disclosures, which means that there will be no clear timing for those. Currently, a Rule 26(a)(2)(A) disclosure can be dropped on an opposing party any time before the pretrial order precludes it.

Under the new regime, the timing of a new Rule 26(a)(2)(C) disclosure can become problematic — and subject to gamesmanship — because the opponent is forced to respond with expert rebuttal within 30 days. If the 26(a)(2)(C) disclosure is disclosed when expert reports are exchanged, there is no problem. Experts are lined up. Counsel are focused on experts. If the 26(a)(2)(C) disclosure is disclosed in the middle of intense discovery or motion practice or some other inopportune time for the recipient (vacation and holidays come to mind), it may be very challenging to arrange the expert testimony necessary to respond to it within 30 days.

Explicitly, the timing of 26(a)(2)(C) summary disclosures and 26(a)(2)(B) reports should be equated. This means that the deposition of the non-reporting expert, on his or her summary, will take place contemporaneously with those of other experts, which is only fair since the expert testimony should be evaluated in the prism of all of the facts, after fact discovery has concluded, and in context with other expert testimony. At a minimum, the expert rebuttal to 26(a)(2)(C) summaries should be the same date that expert reports from the rebutting party are due. This, indirectly, will likely have the same effect because the disclosing party will not want to afford months of additional time to an opponent to respond/rebut.

Second Deposition of Non-Reporting Expert. Unless it is addressed in a scheduling or discovery order, if a Rule 26(a)(2)(A) expert has been deposed before the expert’s disclosure has been made under Rule 26(a)(2)(C), leave of court will be required under Rule 30(a)(2)(A)(ii) to depose the expert again on the subject matter of the summary. Leave should not be required. That would amount to needless motion practice in the routine case. The burden of showing that a second deposition is unnecessary should be on the party disclosing the summary. Better yet, 26(a)(2)(C) disclosures should coincide with expert reports and obviate the issue.

Footnote 1. Some of us argued years ago that “data or other information” could, and should, be read to the same effect because “‘[d]ata’ and ‘information’ connote subjects that are factual in nature, not ephemera like ‘mental impressions, conclusions, opinions or legal theories’ of the sort protected by Rule 26(b)(3).” Joseph, Emerging Expert Issues Under the 1993 Disclosure Amendments to the Federal Rules of Civil Procedure, 164 F.R.D. 97, 104 (1996). While some decisions agreed with that approach, the overwhelming majority rule was to the contrary.
