Teva Pharmaceuticals USA, Inc. v. Wendell
1. Whether the two-part standard of reviewing expert-admissibility rulings employed by the Ninth Circuit, along with the Third and Seventh Circuits, improperly empowers these courts to reverse district court decisions to exclude evidence without “the deference that is the hallmark of abuse-of-discretion review.” Joiner, 522 U.S. at 143.
2. Whether an expert’s qualifications and mere invocation of a scientific methodology can be sufficient to require admission of his testimony, as the Ninth Circuit concluded, or whether Rule 702 requires that a witness, no matter how qualified, must also satisfy the court that his methodology was “reliably applied to the facts of the case,” as several other circuits have held.
