In Moore, the medical expert was an experienced OB/GYN surgeon who had performed thousands of operations, worked as a medical school professor, used similar surgical tools in the past, and had been part of committees overseeing surgical procedures. The main qualification factor that was at play in the case was that the expert had not used the specific surgical tool at issue in any of his past surgeries. In the lower district court, the expert was precluded from testifying as to the cause of the plaintiff's injuries, because he was found to be unqualified since he had not used the defendant's surgical tool.
In its analysis, the 11th Circuit found that the lower court had improperly blended the first prong of the test evaluating "qualifications" with the second prong of the test exploring "reliability." The 11th Circuit found that the "distinction is not academic" between the two prongs because "[q]ualifications and reliability remain separate prongs . that answer two separate questions." In the 11th Circuit's view, "district courts may not collapse into each other." In regard to the first prong, the court explained, "A witness is qualified as an expert if he is the type of person who should be testifying on the matter at hand." In regard to the second prong, the court went on to state "An expert opinion is reliable if it was arrived at through, among other things, a scientifically valid methodology." Another important observation made by the 11th Circuit was that an expert is qualified "not because of his familiarity with the product at issue, but because of his familiarity with the analysis he was tasked with performing." In its final holding, the 11th Circuit explained that "the district court imposed an admissibility standard on expert qualifications that was too high," and that there was no support for a bright line rule that "an expert witness is qualified to testify regarding the cause of an injury only if he personally used the alleged defective product."
