What is the purpose of "voir dire" in legal proceedings?

The purpose of "voir dire" in legal proceedings is specifically to determine the competency of a witness or juror. This process involves questioning prospective jurors or witnesses to assess their qualifications, biases, and ability to serve impartially or provide credible testimony. During voir dire, attorneys from both sides have the opportunity to evaluate jurors' backgrounds and potential conflicts of interest, thus ensuring that the jurors selected can fairly and justly participate in the trial. This step is crucial for maintaining the integrity of the legal process and ensuring a fair trial, as a biased or unqualified juror could negatively impact the verdict.

In contrast, presenting evidence involves showing relevant facts to the court, issuing a verdict is the responsibility of the jury after deliberation, and arguing a case refers to the advocacy presented by the attorneys to support their respective positions in the trial. While important in their own right, these actions do not describe the specific intent and process associated with voir dire.
