266. If, on the day of the trial, a party does not produce witnesses or fails to justify the absence of its witnesses, its evidence is declared closed.
However, if the party proves that it has been diligent and shows that the absent witness is necessary and that the witness’s absence is not due to any contrivance on its part, the court may adjourn the trial. The adjournment can be avoided if the other party consents to the party stating under oath the facts the defaulting witness would have related, and either admits the truth of those facts or admits that the witness would have testified to those facts.
