“There can be but one final judgment in an action, and that is one which in effect ends the suit in the court in which it is entered, and finally determines the rights of the parties in relation to the matter in controversy.” (San Joaquin County Dept. of Child Support Services v. Winn (2008) 163 Cal.App.4th 296, 300, 77 Cal.Rptr.3d 470, 472.) Under the “one final judgment” rule, an appeal will only lie from the final judgment; not from intermediate rulings. (Kinsmith Financial Corp. v. Gilroy (2003) 105 Cal.App.4th 447, 452, 129 Cal.Rptr.2d 478, 481; Maier Brewing Co. v. Pacific Nat. Fire Ins. Co. (1961) 194 Cal.App.2d 494, 497, 15 Cal.Rptr. 177, 179.)
The flip side of the one-final judgment rule is Rule 1, above — that if a judgment or order is appealable, aggrieved parties must file a timely appeal or forever lose the opportunity to obtain appellate court review. (Eisenberg, Horvitz & Weiner, California Practice Guide — Civil Appeals and Writs (Rutter 2009 rev.)(“Civil Appeals”)§ 2:13, emphasis in text.) This is a jurisdictional principle: Appellate courts have no discretion to entertain appellate or writ review of appealable judgments or orders from which a timely appeal was not taken. (Id., citing Code Civ. Proc. § 906; Marriage of Weiss (1996) 42 Cal.App.4th 106, 119, 49 Cal. Rprt. 2d 339, 348.) A related rule is that when appellate review of a particular order is mandated by writ (a “statutory writ”) and the statute provides that this is the exclusive manner to obtain review, the failure to file a timely statutory writ will forfeit the right to later appellate review. (Civil Appeals, ¶ 15:96.1.)
The potential trap for trial lawyers then, is that a court issues a ruling or order that is deemed final or appealable, and the lawyer fails to appeal at the time, thinking instead that the matter will be addressed in the appeal from the final judgment.
There is no easy, all-purpose rule to apply to avoid this problem. Instead, trial lawyers can protect themselves by (a) being familiar with section 904.1 of the Code of Civil Procedure, which sets forth which orders are appealable; and (b) having a passing understanding of the workings of the one-final judgment rule, and its exceptions, which allow appeals from less-than-final judgments or orders.
