probative value

probative value

n. evidence which is sufficiently useful to prove something important in a trial. However, probative value of proposed evidence must be weighed against prejudice in the minds of jurors toward the opposing party or criminal defendant. A typical dispute arises when the prosecutor wishes to introduce the previous conduct of a defendant (particularly a criminal conviction) to show a tendency toward committing the crime charged, against the right of the accused to be tried on the facts in the particular case and not prejudice him/her in the minds of the jury based on prior actions.
