Opinion Evidence (Lay Witnesses) (F.R.E. 701) (revised 2017) is testimony from a witness who is not an expert regarding their opinion on a certain matter. This type of evidence is limited to opinions that are: (1) rationally based on the witness’s perception; (2) helpful to clearly understanding the witness’s testimony or to determining a fact in issue; and (3) not based on scientific, technical, or other specialized knowledge within the scope of Rule 702. There are two types of opinion evidence (lay witnesses) (F.R.E. 701) (revised 2017): (1) lay opinion testimony; and (2) lay opinion on ultimate issue. Lay opinion testimony is testimony from a witness regarding their opinion on a certain matter, which is based on the witness’s personal knowledge, experience, or observations. Lay opinion on ultimate issue is testimony from a witness regarding their opinion on the ultimate issue in the case, which is based on the witness’s personal knowledge, experience, or observations.
