The principal issue presented by this motion is whether, after rehearing is denied and our judgment on the appeal proper is final in this court, we still retain jurisdiction to rule on peremptory exceptions which had been filed prior to our denial of rehearing.
By our original opinion of March 21, 1967, we reversed a trial court judgment which had dissolved a writ of sequestration *703obtained by the plaintiffs-appellants. La. App., 197 So.2d 154. On April 17, 1967, the defendant-appellee filed for the first time in this court, LSA-CCP Art. 2163,1 certain pleadings which he termed peremptory exceptions of “non-joinder of indispensable parties”, LSA-CCP Arts. 645, 927, and of “no cause of action”, LSA-CCP Art. 927. On April 20, 1967, this court disposed of the defendant-appellee’s timely filed application for rehearing by simple per curiam denial.
Our denial of rehearing did not expressly rule upon the “peremptory” exceptions filed three days earlier. However, the usual rule is that the silence of the judgment as to any relief that might have been allowed under the pleadings constitutes a denial of such relief requested. Edenborn v. Blacksher, 148 La. 296, 86 So. 817; R. F. Mestayer Lumber Co. v. Cusack, La.App. 4 Cir., 141 So.2d 166. We felt that, under this general rule, our decree denying the application for rehearing necessarily disposed of the pending exceptions.2
Nevertheless, on April 24, 1967 (four days after rehearing was denied by this court), the defendant-appellee by the present formal motion requests us to make an independent ruling upon the “peremptory” exceptions filed before our denial of rehearing. Had we felt the exceptions were substantially based, at the time we denied rehearing we might well have stated our formal reasons for considering them without merit and untimely.3 However, we cannot now grant the defendant-appellee’s *704motion for a formal independent ruling upon such exceptions because we no longer have jurisdiction to do so.
Because the judgment of a court of appeal becomes final upon the court’s denial of an application for rehearing (if the right to apply for further rehearing is not reserved),4 the court is without jurisdiction to consider even well-founded motions filed after denial of rehearing. Orrell v. Southern Farm Bureau Casualty Insurance Co., La.App., 174 So.2d 841, certiorari denied, 247 La. 1013, 175 So.2d 301; ruling approved, Orrell v. Southern Farm Bureau Casualty Insurance Co., 248 La. 576, 180 So.2d 710 at 713, syllabus 4. After its judgment has become final by its denial of the application for rehearing, a court of appeal cannot by subsequent ruling change the substance 5 of its final decision. Luckett & Hunter v. Texas & P. R. Co., 161 La. 175,108 So. 405.
We therefore deny the defendant-appel-lee’s motion requesting this court to make an independent ruling disposing of the “peremptory” exceptions, since we lack further jurisdiction to act in this appeal after our judgment deciding it became final in this court by our denial of rehearing.
