The Use of Experts — Selected Issues
By: Russell L. Munsch (Co-speaker) I. Introduction II. Statutory Predicates for Expert Witness Testimony If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise. Rule 702 provides a statutory exception to the restriction on opinion testimony applicable to lay persons set forth at Rule 701.1 Rule 104(a) provides that it is the court which shall determine the qualifications of an individual to be an expert witness in accordance with Rule 702. Such determinations are to be made by the court by a "preponderance of proof." See Bourjaily v. United States, 483 U.S. 171, 175-76 (1987). Review of a federal court's decisions regarding the admissibility of expert testimony is conducted utilizing an "abuse of discretion" standard. See General Elec. Co. v. Joiner, 118 S. Ct. 512 (1997).
