Rules of Court
Section 3. Requisites of motion to postpone trial for absence of evidence. - A motion to postpone a trial on the ground of absence of evidence can be granted only upon affidavit showing the materiality or relevancy of such evidence, and that due diligence has been used to procure it. But if the adverse party admits the facts to be given in evidence, even if he objects or reserves the right to object to their admissibility, the trial shall not be postponed.
