a void order in no way affected the rights of the parties. (Stanton v. Superior Court, 202 Cal. 478 [261 P. 1001]; see, also, Felton Chemical Co. v. Superior Court, 33 Cal.App.2d 622 [92 P.2d 684].) Moreover, since the order purporting to modify and change the judgment from an interlocutory to a final one was void, it did not change the nature of the judgment, and therefore was not a special order after final judgment. It was therefore nonappealable and may be changed at any time before entry of a final judgment.
Appellants place great reliance on Hough v. Hough, 26 Cal.2d 605 [160 P.2d 15], in support of their contention that the ruling on the application for the appointment of a referee that the judgment was a final one is now res judicata. That case properly held that a ruling made on an application to modify a divorce decree, which ruling had become final, was res judicata. This power was exercised pursuant to the express provisions of section 137 of the Civil Code conferring jurisdiction on the superior court to modify divorce decrees at any time insofar as they relate to support. In passing on such an application the trial court obviously has the power to interpret the decree in order to determine what it is being asked to modify. The case has no application at all to the controversy now before this court.
Appellants also point out that, some time ago, they petitioned the appellate court for a writ of supersedeas in connection with the appeal. In that proceeding respondents opposed the petition, on several grounds, one being that the judgment was interlocutory. The petition was denied without prejudice to its renewal. It is now urged that if the judgment is interlocutory, the court should have dismissed the appeal of its own motion, and, by failing to do so, impliedly ruled that the judgment was a final one. The denial of the petition for supersedeas without prejudice cannot be so construed. Such a denial, except in most unusual eases, of which this is not one, is not res judicata of anything. (Funeral Dir. Assn. v. Board of Funeral Dirs., 22 Cal.2d 104 [136 P.2d 785]; McDonough v. Garrison, 68 Cal.App.2d 318 [156 P.2d 983].)
For the foregoing reasons the motion to dismiss the appeal from the judgment in San Francisco Superior Court Action 356496 is granted.
Ward, J., and Bray, J., concurred.
