Rule 701. Opinion testimony by lay witnesses.

If the witness is not testifying as an expert, the witness' testimony in the form of opinions or inferences is limited to those opinions or inferences which are (a) rationally based on the perception of the witness (b) helpful to a clear understanding of the witness' testimony or the determination of a fact in issue, and (c) not based on scientific, technical, or other specialized knowledge within the scope of Rule 702.

Advisory Committee Note - This rule is the federal rule, verbatim. The 2009 amendment adopts changes made in Federal Rule of Evidence 701 effective December 1, 2000. This amendment is not intended to change the law, but reflects the Utah Supreme Court’s holding in State v. Rothlisberger, 2006 UT 49, ¶¶ 23-24, 147 P.3d 1176.
