The idea behind peremptory challenges is that if both parties have contributed in the configuration of the jury, they will find its verdict more acceptable. The existence of peremptory challenges is argued to be an important safeguard in the judicial process, allowing both the defendant and the prosecution to get rid of potentially biased jurors. Their use allows attorneys to use their training and experience to dismiss jurors who might say the correct thing, but might otherwise harbor prejudices that could infringe the rights of the defendant to a fair trial.
