directed verdict
n. a verdict by a jury based on the specific direction by a trial judge that they must bring in that verdict because one of the parties has not proved his/her/its case as a matter of law (failed to present credible testimony on some key element of the claim or of the defense). A judge in a criminal case may direct a verdict of acquittal on the basis that the prosecution has not proved its case, but the judge may not direct a verdict of guilty, since that would deprive the accused of the constitutional right to a jury trial.
