Issue:
Does the work product doctrine protect from discovery documents prepared by an attorney that are provided to and considered by a testifying expert witness in forming their opinion?
Opinions:
Majority - Michael, Senior District Judge
No. The work product doctrine does not protect from discovery documents that an attorney provides to a testifying expert who considers them in forming an opinion. The 1993 amendments to Federal Rule of Civil Procedure 26(a)(2) and its accompanying Advisory Committee Notes created a bright-line rule requiring disclosure of all materials 'considered' by a testifying expert. This rule supersedes the qualified protection for fact work product and the near-absolute protection for opinion work product under Rule 26(b)(3) in this specific context. The court reasoned that effective cross-examination, which is essential to testing the reliability and independence of expert testimony, requires the opposing party to have access to all information that shaped the expert's conclusions. An expert is deemed to have 'considered' material if they received and read it; they do not need to have explicitly 'relied' upon it. By choosing to provide work product to an expert, an attorney effectively waives the privilege for those materials.
Analysis:
This decision establishes a bright-line rule that prioritizes discovery and transparency in expert testimony over the traditional protections of the work product doctrine. It clarifies that the 1993 amendments to the Federal Rules of Civil Procedure effectively created a waiver of privilege for any information shared with a testifying expert. This forces attorneys to make a strategic choice: either maintain the absolute secrecy of their work product by not sharing it with experts, or provide it to experts to aid their analysis at the cost of having to disclose it to the opposing party. The ruling significantly impacts litigation strategy by making the basis of expert opinions more transparent and subject to scrutiny during cross-examination.
