The purpose of the voir dire examination is to select a fair and impartial jury to decide the case. During the voir dire examination, the judge or attorneys may ask questions to the potential jurors about their backgrounds, beliefs, and attitudes to identify any potential biases that could affect their ability to be impartial in the case. Based on their answers, potential jurors may be challenged for cause or peremptorily removed from the jury pool.
