Daubert Standard -


Illinois follows the Frye standard. Donaldson v. Central Illinois Public Service Co., 199 Ill. 2d 63, 77 (2002). This standard “dictates that scientific evidence is only admissible at trial if the methodology or scientific principle upon which the opinion is based is ‘sufficiently established to have gained general acceptance in the particular field in which it belongs.’” Donaldson, 199 Ill. 2d at 77. This fact is further confirmed by Illinois Rules of Evidence 702.
