In Bernard v. Richoux, 464 So. 2d 856, 860 (La. App. 5 Cir. 1985), the plaintiff assigned as error the trial court's failure to allow the use of peremptory challenges after the jury had been impaneled but before the jury had been sworn. In rejecting this allegation of error, the court stated: The plaintiff's complaint regarding the refusal of the trial judge to allow her to "reserve" at least one peremptory challenge until after the jury was selected but before being sworn is meritless. This procedure is without precedent in our law and our knowledge and experience, and appellant cites no authority whatsoever for same. (Bernard, 464 So. 2d at 860.)
