Can a plaintiff bring an amended complaint in a promissory estoppel case?

As we explained above, an amended complaint relates back to an earlier complaint if the amended complaint is based on the same general set of facts, even if the plaintiff alleges a different legal theory or new cause of action. (Smeltzley v. Nicholson Mfg. Co. , supra , 18 Cal.3d at pp. 934, 936, 136 Cal.Rptr. 269, 559 P.2d 624.) The promissory estoppel cause of action, though a new cause of action, was based on generally the same facts as the prior complaints, related back to those complaints, and therefore was not barred by a two-year statute of limitations.
