Tenn. R. Civ. P. 32.03
As amended through November 4, 2024
A party does not make a person the party's own witness for any purpose by taking the person's deposition. The introduction in evidence of the deposition or any part thereof for any purpose other than that of contradicting or impeaching the deponent makes the deponent the witness of the party introducing the deposition, but this shall not apply to the use by an adverse party of a deposition under Rule 32.01(2). At the trial or hearing any party may rebut any relevant evidence contained in a deposition whether introduced by that party or by any other party.
