Does a defense expert have to be admitted as a witness in a criminal case?

California, United States of America


The following excerpt is from People v. Reardon, 237 Cal.Rptr.3d 347, 26 Cal.App.5th 727 (Cal. App. 2018):

A criminal defendant's right to present his defense shows there will be cases where a defense expert's testimony should be admitted regardless of whether it is necessary . (See People v. Burrell-Hart , supra , 192 Cal.App.3d at pp. 599-600, 237 Cal.Rptr. 654.) After all, a defendant need only raise a reasonable doubt whether the officers actions were lawful to obtain an acquittal on a resisting charge.8
