California, United States of America
The following excerpt is from Banta v. Am. Med. Response, Inc., B255239 (Cal. App. 2016):
The "one final judgment" rule prohibits review of intermediate ruling until a final resolution of the case, because allowing multiple appeals in a single action is oppressive and costly. (Griset v. Fair Political Practices Com. (2001) 25 Cal.4th 688, 697.) The rule "reduces the ability of litigants to harass opponents and to clog the courts through a succession of costly and time-consuming appeals." (Flanagan v. United States (1984) 465 U.S. 259, 264.)
