Under Rule 41(b) when a plaintiff in an action tried by the Court without a jury has completed the presentation of his evidence, the defendant, without waiving his right to offer evidence in the event the motion is not granted, may move for a dismissal on the ground that upon the facts and the law plaintiff has shown no right to relief.
Federal Rule of Civil Procedure 41(b), provides as follows: 'Involuntary Dismissal: Effect Thereof. 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. Unless the court in its order for dismissal otherwise specifies, a dismissal under this subdivision and any dismissal not provided for in this rule, other than a dismissal for lack of jurisdiction, for improper venue, or for failure to join a party under Rule 19, operates as an adjudication upon the merits.'
Rule 41(b) sets forth nothing more than a default rule for determining the import of a dismissal (a dismissal is 'upon the merits,' with the three stated exceptions, unless the court 'otherwise specifies').
