That which has some force or effect, but which, in consequence of some inherent quality, may be legally annulled or avoided. 2. As a familiar example, may be mentioned the case of a contract, made by an infant with an adult, which maybe avoided or confirmed by the former on his coining of age. Vide Parties, contracts. 3. Such contracts are generally of binding force until avoided by the party having a right to annul them. An old French word, which signifies the same as the modern word vrai, true. Voir dire, to speak truly, to tell the truth. 2. When a witness is supposed to have an interest in the cause, the party against whom he is called has the choice to prove such interest by calling another witness to that fact, or be may require the witness produced to be sworn on his voir dire as to whether he has an interest in the cause, or not, but the party against whom he is called will not be allowed to have recourse to both methods to prove the witness interest. If the witness answers he has no interest, he is competent, his oath being conclusive; if he swears he has an interest, he will be rejected. 3. Though this is the rule established beyond the power of the courts to change, it seems not very satisfactory. The witness is sworn on his voir dire to ascertain whether he has an interest, which would disqualify him, because he would be tempted to perjure himself, if he testified when interested. But when he is asked whether he has such an interest, if he is dishonest and anxious to be sworn in the case, he will swear falsely he has none, and his answer being conclusive, he will be admitted as competent; if, on the contrary, he swears truly he has an interest, when he knows that will exclude him, he is told that for being thus honest, he must be rejected.
