In the lead article in this symposium issue, Edward Imwinkelried follows other scholars in distinguishing among three types of tasks for ethicists serving as expert witnesses: (1) descriptive (e.g., addressing the existence and content of relevant codes of ethics or guidelines, or the correspondence, or lack of correspondence, between relevant codes or guidelines and the parties’ practices); (2) metaethical (e.g., clarifying concepts, critiquing the logic of a particular argument or position); and (3) normative (e.g., addressing what the standard or practice should be). He finds agreement that the admissibility of descriptive or metaethical evidence rests upon the usual criteria of helpfulness and reliability. He breaks new ground in arguing that normative evidence typically relates to the judge's legislative rather than adjudicative function and therefore need not satisfy the usual standards for admissibility in order to be considered.
