Voir dire (French for 'to speak the truth') is a legal procedure with two main applications. In jury selection, voir dire is the process of questioning potential jurors to assess their suitability and identify those who should be excluded for bias or inability to serve fairly. In criminal trials, voir dire refers to a trial-within-a-trial where the judge determines the admissibility of evidence—particularly confessions—without the jury present. During voir dire on evidence admissibility, the judge hears arguments about whether evidence was obtained properly and should be allowed. If excluded, jurors never hear the evidence; if admitted, it becomes part of the trial. Voir dire proceedings address procedural and evidentiary matters separate from determining guilt.
