Committee Notes

Advisory Commission Comments.

Tennessee has long admitted animal habit. Copley v. State , 153 Tenn. 189, 281 S.W. 460 (1925), is the leading case. Authorities supporting admissibility of human habit and business custom are collected in Tennessee Law of Evidence § 30.

The second paragraph defines habit and routine practice, emphasizing the need for a "regular response" when a person, animal, or organization is faced with a given situation.
