This report to the Judicial Conference Committee on Court Administration and Case Management describes two different types of independent panels used in the silicone gel breast implants litigation. The use of such panels of appointed experts represents a marked departure from the traditional means of presenting and considering testimony. This report describes these expert panels in sufficient detail to permit others to understand the procedures that were used, the benefits that resulted, and the problems that arose. A similar version of this report was originally delivered to the Committee in November 1999.
