[50] For reasons that I will more fully outline, the purpose of Rule 53.03 is to ensure the expert witness’ independence and integrity. The expert’s primary duty is to assist the court. In light of this change in the role of the expert witness, I conclude that counsel’s prior practice of reviewing draft reports should stop. Discussions or meetings between counsel and an expert to review and shape a draft expert report are no longer acceptable.
[51] If after submitting the final expert report, counsel believes that there is need for clarification or amplification, any input whatsoever from counsel should be in writing and should be disclosed to opposing counsel.
[52] I do not accept the suggestion in the 2002 Nova Scotia decision, Flinn v. McFarland, 2002 NSSC 272 (CanLII), 2002 NSSC 272, 211 N.S.R. (2d) 201, that discussions with counsel of a draft report go to merely weight. The practice of discussing draft reports with counsel is improper and undermines both the purpose of Rule 53.03 as well as the expert’s credibility and neutrality.
