History
Comment D.R.E. 702 was amended in 2001 to track F.R.E. 702 in effect on December 31, 2000. D.R.E. 702 is consistent with the United States Supreme Court’s decisions in Kumho Tire Co., Ltd v. Carmichael, 526 U.S. 137 (1999) and Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579 (1993). See also M.G. Bancorporation, Inc. v. LeBeau, Del. Supr., 737 A.2d 513 (1999) (adopting Kumho Tire and Daubert as the correct interpretation of D.R.E. 702), Nelson v. State, Del. Supr., 628 A.2d 69 (1993). D.R.E. 702 was amended in 2017 in response to the 2011 restyling of the Federal Rules of Evidence. The amendment is intended to be stylistic only. There is no intent to change any result in ruling on evidence admissibility.
