On December 2, 2010, the Civil Rules Advisory Committee amended Rules 26(a)(4)(B) and (C) to provide work-product protection to draft expert reports and, with three exceptions, attorney-expert communications. These rules provide thus:
(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 of the draft.
(C) Trial Preparation Protection for Communications Between 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:
(i) relate to compensation for the expert’s study or testimony;
(ii) identify facts or data that the party’s attorney provided and that the expert considered in forming the opinions to be expressed; or
(iii) identify assumptions that the party’s attorney provided and that the expert relied upon in forming the opinions to be expressed.
Federal Rule of Civil Procedure 26(b)(4)(A) notes that,
[o]rdinarily, a party may not discover documents and tangible things that are prepared in anticipation of litigation or for trial by or for another party or its representative (including the other party’s attorney, consultant, surety, indemnitor, insurer, or agent). But, subject to Rule 26(b)(4), those materials may be discovered if: (i) they are otherwise discoverable under Rule 26(b)(1); and (ii) the party shows that it has substantial need for the materials to prepare its case and cannot, without undue hardship, obtain their substantial equivalent by other means.
Furthermore, Rule 26(b)(4)(B) provides that “[i]f the court orders discovery of those materials, it must protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of a party’s attorney or other representative concerning the litigation.”]
The following is a collection of recent cases under Rules 26(a)(4)(B) and (C) .
