Disagreeing with Muller v. Fresno Community Hospital & Medical Center (2009) 172 Cal.App.4th 887, this decision holds that the California Supreme Court has not abandoned its requirement that for an order to be appealable under the collateral order doctrine, the order must direct payment of money or performance of an act. That requirement remains a restriction on collateral order appeals in state court. Accordingly, an order denying summary judgment on a defense of the statute of repose under the federal General Aviation Revitalization Act (49 USC 40101 note) is not appealable.
