MEMORANDUM

Plaintiff-Appellant Aaron Tribble (“Tribble”) filed a complaint against his former employer Defendant-Appellee Ray-theon Company (“Raytheon”), asserting two claims for relief: (1) retaliation in violation of the False Claims Act, 31 U.S.C. § 3730 (h), and (2) wrongful termination in violation of public policy, a California state law tort. The district court granted Raytheon’s motion for summary judgment on both claims. We affirm.

a. Tribble’s False Claims Act Retaliation Claim

“A plaintiff alleging a [False Claims Act] retaliation claim must show three elements: (1) that he or she engaged in activity protected under the statute; (2) that the employer knew the plaintiff engaged in protected activity; and (3) that the employer discriminated against the plaintiff because he or she engaged in protected activity.” Mendiondo v. Cen-tinela Hosp. Med. Ctr., 521 F.3d 1097, 1103 (9th Cir.2008).

The district court correctly concluded that Tribble was not engaged in protected activity under the False Claims Act because there is no evidence to suggest that Tribble had a good faith belief that Ray-theon was “possibly committing fraud against the government.” Moore v. Cal. Inst. of Tech. Jet Propulsion Lab., 275 F.3d 838, 845 (9th Cir.2002). Tribble’s evidence merely shows that in the course of doing his job, he stated in a PowerPoint presentation that a failed night vision unit returned by a South Korean customer may have had a latent defect and that further testing was necessary to determine the cause of the unit’s failure. There is no evidence that Tribble took any additional steps to pursue the alleged latent defect after the submission of his PowerPoint presentation, nor that he believed Ray-theon’s failure to investigate the latent defect constituted fraud against the U.S. government.

Further, even if Tribble was engaged in protected conduct, Raytheon had no notice that Tribble was engaged in such conduct because Tribble never indicated to anyone at Raytheon that he was concerned about fraud or false claims against the U.S. government. Thus, the district court did not err in granting summary judgment in favor of Raytheon on Tribble’s federal False Claims Act claim.

b. Wrongful Termination in Violation of Public Policy

Tribble’s state law tort claim alleged in his First Amended Complaint fo cuses entirely on the theory that Tribble was wrongfully terminated in violation of the policies underlying the False Claims Act. Tribble’s attempt to argue at the summary judgment stage, and to this court, that he was wrongfully terminated in violation of the policies underlying Title 48 of the Code of Federal Regulations is impermissible under Federal Rule of Civil Procedure 8. See Kearns v. Ford Motor Co., 567 F.3d 1120, 1125 (9th Cir.2009) (“[T]he Federal Rules of Civil Procedure apply in federal court, irrespective of the source of the subject matter jurisdiction, and irrespective of whether the substantive law at issue is state or federal.” (internal quotation marks and citation omitted)); see also Pickern v. Pier 1 Imports (U.S.), Inc., 457 F.3d 963, 968 (9th Cir.2006) (“Rule 8’s liberal notice pleading standard ... requires that the allegations in the complaint ‘give the defendant fair notice of what the plaintiffs claim is and the grounds upon which it rests.’” (citation omitted)).

Because Tribble’s claim of wrongful termination in violation of public policy is a California state law claim, we apply California substantive law. Bass v. First Pac. Networks, Inc., 219 F.3d 1052 , 1055 n. 2 (9th Cir.2000) (“[A] federal court exercising supplemental jurisdiction over state law claims is bound to apply the law of the foi'um state.... ”). Under Califox'nia law, “when the ... statute articulating a public policy also includes certain substantive limitations in scope or remedy, these limitations also circumscribe the common law wrongful discharge cause of action”.

Stated another way, “the common law cause of action cannot be broader than the ... statute on which it depends.... ” City of Moorpark v. Superior Court, 18 Cal.4th 1143, 1159 , 77 Cal.Rptr.2d 445 , 959 P.2d 752 (1998). The district eoui’t corx'ectly concluded that Tribble’s “state law claim for wrongful tex’mination in violation of public policy [under the False Claims Act] fails for the same x*easons as his [federal False Claim Act] claim fails.”

AFFIRMED.
