Tenn. R. Evid. 613
Advisory Commission Comments.
The rule eliminates any necessity of showing an inconsistent writing to a fact witness under impeachment attack. The only requirement is that, where the impeaching lawyer introduces extrinsic evidence of the inconsistent statement, the fact witness must be "afforded an opportunity to explain or deny." The rule will not change drastically Tennessee procedure. Compare Moore v. Bettis, 30 Tenn. 67 (1850), with Titus v. State, 66 Tenn. 132 (1874).
Part (c) would change such hypertechnical results as that reached in Saunders v. City & Suburban Railroad, 99 Tenn. 130, 41 S.W. 1031 (1897), excluding a prior inconsistent statement characterized as an "opinion". Obviously an opinion inconsistent with a fact should be admissible.
Advisory Commission Comment [2003].
Paragraph (b) is amended to add the words "and until." The effect is to incorporate the holding in State v. Martin, 964 S.W.2d 564 (Tenn. 1998): "extrinsic evidence remains inadmissible until the witness either denies or equivocates as to having made the prior inconsistent statement."
Note that Rule 806 does not require a foundation before impeaching a hearsay declarant by inconsistent statement.
