Justipedia explains Testimony
When a layperson gives testimony in court (as opposed to a person who is able to give expert testimony), his or her testimony is limited to the rationally based perceptions of the situation or circumstance in question. That person's testimony is limited to opinions and/or inferences that would be helpful to a clear understanding of the witness's full testimony. This type of in-court testimony is vitally important to the outcome of a civil or criminal case.
