Advisory Commission Comments.
This rule gives a lawyer the option of not using a hypothetical question in examining an expert; the lawyer can ask the expert simply to state an opinion. Tennessee presently requires the hypothetical unless the expert bases testimony on personal observation. See, e.g., Valentine v. Conchemco, 588 S.W.2d 871 (Tenn. Ct. App. 1979).
