A peremptory challenge is a legal term used in jury selection that allows attorneys to reject a certain number of potential jurors without providing a reason. This process is part of the trial procedure in many legal systems, including those in the United States. Each side in a trial typically has a limited number of peremptory challenges, which they can use to shape the jury according to their strategy. These challenges are distinct from for-cause challenges, where an attorney must provide a valid reason to dismiss a juror, such as bias or conflict of interest. Peremptory challenges help ensure that both the defense and prosecution can influence the composition of the jury, promoting a fairer trial process.
