   MEMORANDUM

Ravindra K. Patel and Yogi Krupa, Inc. appeal the district court’s dismissal with prejudice for lack of subject matter jurisdiction of their first amended complaint alleging one claim, for violation of the Racketeer Influenced and Corrupt Organizations Act, 18 U.S.C. § 1961, et seq. Having conducted a de novo review, we hold that the district court’s decision was not clearly erroneous. Kruso v. Int’l Tel. & Tel. Corp., 872 F.2d 1416, 1421 (9th Cir.1989); Griggs v. Pace Am. Group, Inc., 170 F.3d 877, 879 (9th Cir.1999). Accordingly, we affirm.

The district court applied the substantiality doctrine in finding that it lacked subject matter jurisdiction. “Under the substantiality doctrine, the district court lacks subject matter jurisdiction when the question presented is too insubstantial to consider.” Cook v. Peter Kiewit Sons Co., 775 F.2d 1080, 1035 (9th Cir.1985) (citing Hagans v. Lavine, 415 U.S. 528, 536-39, 94 S.Ct. 1372, 39 L.Ed.2d 577 (1974)). “The claim must be ‘so insubstantial, implausible, foreclosed by prior decisions of this Court or otherwise completely devoid of merit as not to involve a federal controversy within the jurisdiction of the District Court, whatever may be the ultimate resolution of the federal issue on the merits.’ ” Id. (quoting Oneida Indian Nation v. County of Oneida, 414 U.S. 661, 666, 94 S.Ct. 772, 39 L.Ed.2d 73 (1974)).

Appellants’ allegation that defendantsappellees Kishor and Gita Patel engaged in a pattern of racketeering activity by dealing in obscene matter is devoid of merit under both 18 U.S.C. §§ 1961(1)(A) and (B). We have not considered appellants’ Federal Rule of Appellate Procedure 28(j) letter filed on May 4, 2012 because it raises new arguments, which we consider waived for purposes of this appeal. Confederated Tribes v. Bonneville Power Admin., 342 F.3d 924, 933 (9th Cir.2003); Medina-Morales v. Ashcroft, 362 F.3d 1263, 1269 n. 6 (9th Cir.2004). This decision does not foreclose appellants from bringing their new theory in a new ease. Cook, 775 F.2d at 1035. Appellees’ request for judicial notice is denied as moot. (Doc. No. 21.)

AFFIRMED.
