2024However, because the case is being remanded for a new trial, and the issue will likely arise again on remand, we briefly address defendant’s third argument related to the denial of her motion for a Frye hearing. ¶ 42 “In Illinois, scientific evidence is admissible at trial only if it meets the standard expressed in Frye, which dictates that ‘scientific evidence is admissible at trial only 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.” ’ ” People v.

2024Frye Hearing ¶ 53 Plaintiffs also argue that the trial court erred by excluding evidence of Busch’s physician’s query with Dr. Stams without holding a Frye hearing. “[T]he Frye standard dictates that scientific evidence is admissible at trial only 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.’ ” In re Commitment of Simons, 213 Ill. 2d 523, 529 (2004) (quoting Frye, 293 F. at 1014 ); see Ill.

2010Further, the Frye test is necessary only if the scientific principle, technique or test offered by the expert to support his or her conclusion is “new” or “novel.” See People v. Basler, 193 Ill. 2d 545, 550-51 (2000).

McKown (McKown I), 226 Ill. 2d 245, 254 (2007). ¶ 50 The admission of expert testimony in Illinois is governed by the Frye “general acceptance test.” Under Frye, “scientific evidence is admissible at trial only 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.’ ” Simons, 213 Ill. 2d at 529 -30 (quoting Frye, 293 F. at 1014 ). “[T]he Frye test is necessary only if the scientific principle, techn

2014Defendant claims that given “fierce disagreement” in the medical community as to the legitimacy of the SBS diagnosis, “it is difficult to imagine how the diagnosis can ever be deemed ‘generally accepted’ under Frye.” “The ‘general acceptance’ test set forth in Frye provides that scientific evidence is admissible at trial only 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.
