The difference between extrinsic and intrinsic fraud is as follows: "'By contrast, fraud is intrinsic and not a valid ground for setting aside a judgment when the party has been given notice of the action and has had an opportunity to present his case and to protect himself from any mistake or fraud of his adversary but has unreasonably neglected to do so. ' " (Navarro v. IHOP Properties, Inc. (2005) 134 Cal.App.4th 834, 844; see Cedars-Sinai Medical Center v. Superior Court, supra, 18 Cal.4th at pp. 10-11; La Salle v. Peterson (1934) 220 Cal. 739 at pp. 740-742.) Thus, intrinsic fraud occurs during the course of the proceedings through fraudulently suppressed, concealed or falsified evidence and does not provide a basis for equitable relief. (Cedars-Sinai Medical Center v. Superior Court (1998) 18 Cal.4th 1 at pp. 10-11; La Salle v. Peterson, supra, 220 Cal. at pp. 740-742.)
