Mississippi Code Title 99. Criminal Procedure § 99-15-29

On all applications for a continuance the party shall set forth in his affidavit the facts which he expects to prove by his absent witness or documents that the court may judge of the materiality of such facts, the name and residence of the absent witness, that he has used due diligence to procure the absent documents, or presence of the absent witness, as the case may be, stating in what such diligence consists, and that the continuance is not sought for delay only, but that justice may be done. The court may grant or deny a continuance, in its discretion, and may of its own motion cross-examine the party making the affidavit. The attorneys for the other side may also cross-examine and may introduce evidence by affidavit or otherwise for the purpose of showing to the court that a continuance should be denied. No application for a continuance shall be considered in the absence of the party making the affidavit, unless his absence be accounted for to the satisfaction of the court. A denial of the continuance shall not be ground for reversal unless the supreme court shall be satisfied that injustice resulted therefrom.
