What document offers an alternative to the Frye standard that some courts believe espouses a more flexible standard for admitting scientific evidence?
Weegy: Daubert v. Merrell Dow Pharmaceuticals, which held that Rule 702 of the Federal Rules of Evidence did not incorporate the Frye "general acceptance" test as a basis for assessing the admissibility of scientific expert testimony; General Electric Co. [ v. Joiner,[1] which held that an abuse-of-discretion standard of review was the proper standard for appellate courts to use in reviewing a trial court's decision of whether expert testimony should be admitted; Kumho Tire Co. v. Carmichael,[2] which held that the judge’s gatekeeping function identified in Daubert applies to all expert testimony, including that which is non-scientific. Two of the most important appellate level opinions that clarify the standard include Judge Kozinski's opinion in Daubert on remand (Daubert v. Merrell Dow Pharmaceuticals, Inc., 43 F.3d 1311 (9th Cir. 1995)), and Judge Becker's opinion in In re Paoli R.R. Yard PCB Litig., 35 F.3d 717 (3d Cir. 1994). Weisgram v Marley Co, 528 US 440 (2000) is also considered a significant case.[3] ] (More)
