Voir dire

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Voir dire (/ˈvwɑːr ˌdiər/) is a legal phrase that refers to a variety of procedures connected with jury trials. It originally referred to an oath taken by jurors to tell the truth (Latin: verum dicere), i.e., to say what is true, what is objectively accurate or subjectively honest, or both. It comes from the Anglo-Norman language.

The word voir (or voire), in this combination, comes from Old French and derives from Latin verum, "that which is true". It is not related to the modern French word voir, which derives from Latin vidēre ("to see"), though the expression is now often interpreted by false etymology to mean "to see [them] say".

Historic use[edit]

In earlier centuries, a challenge to a particular juror would be tried by other members of the jury panel, and the challenged juror would take an oath of voir dire, meaning to tell the truth.[1] This procedure fell into disuse when the function of trying challenges to jurors was transferred to the judge.

Use in Commonwealth countries and Ireland[edit]

In the United Kingdom (except Scotland), Cyprus, Hong Kong, Ireland, Australia, New Zealand, and Canada (and sometimes in the United States of America) it refers to a "trial within a trial". It is a hearing to determine the admissibility of evidence, or the competency of a witness or juror.[2] As the subject matter of the voir dire often relates to evidence, competence or other matters that may lead to bias on behalf of the jury, the jury may be removed from the court for the voir dire.

The term has thus been broadened in Australian jurisdictions to include any hearing during a trial where the jury is removed. The High Court of Australia has noted that the voir dire is an appropriate forum for the trial judge to reprimand counsel or for counsel to make submissions as to the running of the court to the trial judge.[3]

Under Scots law, jury selection is random, and there are a few well-defined exclusions in criminal trials.[4]

Use in the United States[edit]

USA v. Mohammed Hashim -- Defense voir dire of military judge

In the United States, it now generally refers to the process by which prospective jurors are questioned about their backgrounds and potential biases before being chosen to sit on a jury. "Voir Dire is the process by which attorneys select, or perhaps more appropriately reject, certain jurors to hear a case."[5] It also refers to the process by which expert witnesses are questioned about their backgrounds and qualifications before being allowed to present their opinion testimony in court. As noted above, in the United States (especially in practice under the Federal Rules of Evidence), voir dire can also refer to examination of the background of a witness to assess their qualification or fitness to give testimony on a given subject.[6] Voir dire is often taught to law students in trial advocacy courses.[7]

References in popular culture[edit]

In the 1992 movie "My Cousin Vinny", starring Joe Pesci and Marisa Tomei, there is an exchange between District Attorney Trotter and Vincent Gambini (Pesci) that uses the term "voir dire".

TROTTER: Your honor, I object to this witness. Improper foundation. I am not aware of this person’s qualifications. I’d like to voir dire this witness as to the extent of her expertise.
After some questioning about Mona Lisa Vito's (Tomei) qualifications as a mechanic, the exchange continues...
TROTTER: Ok. Ok, but does being an ex-mechanic necessarily qualify you as being an expert on tire marks?
MS VITO: No, it doesn’t. Good-bye.
JUDGE: Sit down and stay there until you’re told to leave.
VINNY: Your Honor, Ms. Vito’s expertise is in general automotive knowledge. It is in this area that her testimony will be applicable. If Mr. Trotter wishes to voir dire the witness as to the extent of her expertise in this area, I’m sure he’s going to be more than satisfied.
