The Federal Judicial Center and National Research Council have issued the third edition of the Reference Manual on Scientific Evidence, which courts use to understand complex expert testimony and scientific evidence produced at trial. The manual is available online at no charge; it aims to provide judges with a background on undisputed scientific matters so they are prepared to either admit or exclude expert testimony in pending litigation. Consisting of 1,038 pages, the manual includes several new chapters on scientific evidence, unavailable when it was first published in 1994. According to a U.S. district court judge who co-chaired the committee that oversaw the third edition’s production, the new chapters address advances in neuroscience research and forensic science.
