Foreign Language Translators/ Interpreters as Expert Witnesses in Federal Courts
Fed. R. Evid. 604 states that "(a)n interpreter is subject to the provisions of these rules relating to qualification as an expert . . . ." Even though this rule explicitly applies only to interpreters (who translate spoken language), as opposed to translators (who translate written language), no less an authority than Prof. Edward Imwinkelried says, without qualification, that translators are expert witnesses (The Taxonomy of Testimony Post-Kumho: Refocusing on the Bottomlines of Reliability and Necessity, 30 Cumb. L. Rev. 185, 211, fn. 150 (1999-2000)), and the courts generally treat them as such.
