Tenn. R. Civ. P. 41.02

(1) For failure of the plaintiff to prosecute or to comply with these rules or any order of court, a defendant may move for dismissal of an action or of any claim against the defendant.

(2) After the plaintiff in an action tried by the court without a jury has completed the presentation of plaintiff's evidence, the defendant, without waiving the right to offer evidence in the event the motion is not granted, may move for dismissal on the ground that upon the facts and the law the plaintiff has shown no right to relief. The court shall reserve ruling until all parties alleging fault against any other party have presented their respective proof-in-chief. The court as trier of the facts may then determine them and render judgment against the plaintiff or may decline to render any judgment until the close of all the evidence. If the court grants the motion for involuntary dismissal, the court shall find the facts specially and shall state separately its conclusion of law and direct the entry of the appropriate judgment. [As amended by order entered December 14, 2009, effective July 1, 2010.]

(3) Unless the court in its order for dismissal otherwise specifies, a dismissal under this subdivision and any dismissal not provided for in this Rule 41, other than a dismissal for lack of jurisdiction or for improper venue or for lack of an indispensable party, operates as an adjudication upon the merits. [As amended by order effective July 1, 1998.]
