Final answer:
Lawyers challenge jurors during the questioning process to establish an impartial jury as mandated by the Sixth Amendment. This voir dire process is crucial to safeguard the right to a fair trial, allowing lawyers to dismiss potential jurors who may exhibit bias that could affect their judgement.
Step-by-step explanation:
Lawyers challenge jurors during the questioning process to ensure the selection of an impartial jury, which is critical for a fair trial. This process, known as voir dire, involves both the prosecution and defense in asking potential jurors questions to uncover any biases or preconceived notions that might influence their judgement. Lawyers have the right to use challenges, including peremptory challenges and challenges for cause, to dismiss jurors who may not be able to decide a case only on the evidence presented.
During jury selection, potential jurors may have formed opinions due to media coverage or personal experiences that could sway their impartiality. Since the Sixth Amendment mandates the accused's right to a fair trial by an impartial jury, it is imperative for lawyers to use the challenge process to protect this right. An unbiased jury is essential for upholding the integrity of the justice system, ensuring that verdicts are based solely on the evidence and the law, not on prejudice or outside influence.
