CALOGERO, Chief Justice, concurring in the denial of the writ and assigning reasons.

While I join the majority in denying this writ application, I write separately to express the view that Plaintiffs/Relators are free to reurge their motion during the course of the proceeding if it becomes apparent that Mr. Gravelles' testimony is critical to the case. Additionally, Plaintiffs/Relators may seek a remedy on appeal, at which time the court of appeal will have the benefit of a fully-developed record.
