Staff Comment (ADM File No. 2022-30): The amendment of MRE 702 requires the proponent of an expert witness's testimony to demonstrate that it is more likely than not that the factors for admission are satisfied and clarifies that it is the expert's opinion that must reflect a reliable application of principles and methods to the facts of the case. The amendment of MRE 804(b)(4)(B) requires corroborating circumstances of trustworthiness for any statement against interest that exposes a declarant to criminal liability.
