U.S. Supreme Court Extends Expert Testimony Ruling to All Specialized Knowledge

摘要

In March, the U.S. Supreme Court ruled unanimously that U.S. District Courts must subject all "expert" testimony to the same "relevant and reliable" standards used to test the admissibility of scientific testimony. This ruling, which reinforces previous decisions, could affect not only the testimony of individual "experts" but also the validity of regulatory and technical programs subject to judicial review.
