"However, differential diagnosis does not by itself prove the cause, even for the particular patient."
Pursuant to Rules 702, and 703 of the Federal Rules of Evidence, and as outlined in Daubert, 509 U.S. at 579, 113 S.Ct. 2786, and its progeny, Plaintiffs Zelinger and Roberts, as the proponents of the expert testimony, have failed to meet their burden of proof of establishing that the opinions of Drs. Kassan, Klapper, Hoffman, Guidoin, and Blais: (1) are based on valid, scientific principles and reliable scientific methods, processes, reasoning, and data; (2) are based upon data reasonably relied upon by experts in the field, and (3) would assist the trier of fact in resolving a factual dispute in these actions. ... Daubert sets forth several non-exhaustive factors to assist trial courts in determining whether a theory or technique constitutes "scientific knowledge" within the meaning of Rule 702, including whether the methodology, principles and reasoning underlying the proposed experts' opinions: (1) can be and have been empirically tested; (2) have been subjected to peer review and publication; (3) have a known or potential rate of error; and (4) have gained general acceptance in the relevant scientific community.
The Supreme Court in Daubert explained that Federal Rule of Evidence 702 allows the admission of expert testimony only if: (1) the expert is competent and qualified to testify regarding the matters that he intends to address; (2) the methodology by which the expert reaches his conclusions is sufficiently reliable; and (3) the expert, through scientific, technical or specialized expertise, provides testimony that assists the trier of fact to understand the evidence or determine a fact in issue. ... Defendant contends that Plaintiffs' experts' testimony fails to meet the Daubert standards for admissibility because Plaintiffs' experts (1) have failed to provide any evidence, either published or unpublished, that Parlodel® increases one's risk of stroke; (2) rely on uncontrolled and unreliable spontaneous reports and anecdotal case reports as the basis for their opinions; and (3) cannot show that their opinions have an acceptable error rate or are otherwise generally accepted.
The Supreme Court in Daubert stated that Rule 702 required the district court to perform a "gate-keeping function" before admitting expert scientific testimony, to ensure that it is not only relevant, but reliable. ... "Under the Daubert standard, epidemiological studies are not necessarily required to prove causation, as long as the methodology employed by the expert in reaching his or her conclusion is sound."
Daubert thus teaches that "`the trial judge must determine whether [an expert's] opinion was grounded in the "methods and procedures of science," Daubert, [cite] and whether such testimony had sufficient `factual underpinnings.'" ... The principle of Daubert is merely that if an expert witness is to offer an opinion based on science, it must be real science, not junk science.
