   MEMORANDUM

Jonathan D. Cobb, Sr., and Walter Ar-len St. Clair appeal pro se from the district court’s judgment dismissing for lack of subject matter jurisdiction their action alleging that defendants committed acts of conspiracy, fraud, “religious fraud,” mail and wire fraud, defamation and collusion. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Peralta v. Hispanic Bus., Inc., 419 F.3d 1064, 1068 (9th Cir.2005), and we affirm.

The district court properly dismissed the action because the complaint does not allege facts to support federal question or diversity jurisdiction. See id. (“In civil cases, subject matter jurisdiction is generally conferred upon federal district courts either through diversity jurisdiction, 28 U.S.C. § 1332, or federal question jurisdiction, 28 U.S.C. § 1331.”); Gilder v. PGA Tour, Inc., 936 F.2d 417, 421 (9th Cir.1991) (recognizing that, if the parties fail to raise the issue of subject matter jurisdiction, the court must raise it sua sponte); see also Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 89, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998) (“Dismissal for lack of subject-matter jurisdiction because of the inadequacy of the federal claim is proper only when the claim is ‘so insubstantial, implausible, ..., or otherwise completely devoid of merit as not to involve a federal controversy.’ ” (citation omitted)). Even if plaintiffs’ complaint could be construed to contain a RICO claim, plaintiffs failed to allege any injury to a business or property interest. See Diaz v. Gates, 420 F.3d 897, 900 (9th Cir.2005) (en banc) (per curiam) (to state a claim under RICO, the plaintiff must allege “harm to a specific business or property interest”).

Because the district court did not reach the merits of the case due to its sua sponte dismissal for lack of subject matter jurisdiction, we do not consider plaintiffs’ contentions concerning the need for additional discovery.

AFFIRMED.
