Which process refers to conducting a trial within a trial to determine the admissibility of certain evidence?

The process that involves conducting a trial within a trial to determine the admissibility of certain evidence is known as voir dire. This term is typically used in legal settings to refer to the preliminary examination of a witness or a juror by a judge or counsel. The primary purpose of voir dire is to ensure that any testimony given is reliable and that jurors are unbiased.

During voir dire, attorneys may question potential jurors about their backgrounds, beliefs, and any potential conflicts of interest. In some cases, it also serves the role of assessing the admissibility of expert witnesses or specific evidence through a mini-trial, where the arguments about the evidence's relevance and reliability are presented before it is allowed in front of the jury.

The other options refer to different legal processes. Examination generally deals with the questioning of witnesses during a trial, arbitration is a form of alternative dispute resolution where a neutral party makes decisions, and interrogation pertains to questioning suspects or witnesses, often in a law enforcement context. These processes do not specifically address the trial within a trial aspect that voir dire encompasses.
