Rincon Mushroom Corp. of Am. v. Mazzetti
NOT FOR PUBLICATION
Submitted May 20, 2024 [**] San Francisco, California
Appeal from the United States District Court for the Southern District of California D.C. No. 3:09-cv-02330-WQH-JLB William Q. Hayes, District Judge, Presiding
Before: GRABER and FORREST, Circuit Judges, and SELNA [***] District Judge.
Marvin Donius, a non-Indian, owns a five-acre parcel of land (the Property) located within the Rincon Band of Luiseno Indians' (the Tribe) reservation in California. Rincon Mushroom Corporation of America (RMCA) has a financial interest in the Property. After the Tribe asserted regulatory jurisdiction over the Property, Donius and RMCA (collectively, Plaintiffs) sued, challenging the Tribe's regulatory authority. The tribal trial and appellate courts held that the Tribe has regulatory jurisdiction over the Property. Plaintiffs challenged the tribal court's decision in federal district court, which agreed with the tribal court and, consequently, recognized and enforced the tribal court's judgment. Plaintiffs appeal. We have jurisdiction under 28 U.S.C. §1291, and we affirm.
Plaintiffs contend that the tribal court lacked personal jurisdiction over them. Plaintiffs raised this issue in a heading in their summary judgment brief filed in the district court but did not develop the argument. The district court rejected this challenge, noting that "Plaintiffs do not explain the basis for their contention that the Rincon Tribal Court lacked personal jurisdiction over them." We conclude that the Plaintiffs' personal jurisdiction challenge is forfeited. See, e.g., Consumer Fin. Prot. Bureau v. Aria, 54 F.4th 1173 (9th Cir. 2022) (); G & G Prods. LLC v. Rusic, 902 F.3d 940, 950 (9th Cir. 2018) ().
The second Montana exception provides that tribes have sovereign authority to regulate nonmembers' conduct on non-Indian land located within a reservation that "threatens or has some direct effect on the political integrity, the economic security, or the health or welfare of the tribe." Montana v. United States, 450 U.S. 544, 565-66 (1981). When a tribe has regulatory jurisdiction, tribal courts generally have adjudicatory jurisdiction to enforce those regulations. See FMC Corp. v. Shoshone-Bannock Tribes, 942 F.3d 916, 941 (9th Cir. 2019) (). Here, the tribal trial court found that it had subject matter jurisdiction under this principle, and both the tribal appellate court and federal district court agreed. For the reasons that follow, Plaintiffs' challenges to the tribal court's subject matter jurisdiction fail.
The tribal court found that (1) the Property's "condition" and "poor maintenance" posed a significant wildfire risk to the Tribe's nearby casino, which would be catastrophic to the Tribe's economic interests and (2) "the activities on [the] [P]roperty, if allowed to continue unchecked, bear a distinct possibility of damaging [the Tribe's] 'pristine' water table." Plaintiffs dispute these findings because the tribal court did not find that actual fire damage to the casino or contamination of the water table had occurred. But proof of existing harm is not required, see Montana, 450 U.S. at 566 (), and Plaintiffs have not shown that the tribal court's findings regarding the threat of future harm are clearly erroneous, see FMC, 942 F.3d at 930 ( standard). Moreover, we conclude that the possibility of wildfire damage to the tribe's primary source of income and contamination of its sole water source "threatens or has some direct effect on the political integrity, the economic security, or the health or welfare of the tribe." Lexington Ins. Co. v. Smith, 94 F.4th 870, 875-76 (9th Cir. 2024) (quoting Montana, 450 U.S. at 566). The Tribe's "economic security" hinges on the casino gaming operations that are its "major source of revenue." Likewise, "[t]hreats to tribal natural resources . . . constitute threats to tribal self-governance, health and welfare," FMC, 942 F.3d at 935, especially because the natural resource at issue here is the Tribe's "single water source," on which it is "dependent."
The tribal court also found that the local county would not regulate the Property because Indian reservations are exempt from the County's land use ordinances. This finding was supported by evidence and was properly considered by the tribal court. We conclude that the tribal court did not err in concluding that it had subject matter jurisdiction under the second Montana exception. See Plains Com. Bank v. Long Fam. Land & Cattle Co., 554 U.S. 316, 341 (2008) ().[1]
Plaintiffs argue that even if the tribal court had subject matter jurisdiction, the injunction that it entered was impermissibly overbroad. Plaintiffs did not challenge the operative injunction in the tribal appellate court; therefore, this issue is not properly before us. See Elliott v. White Mountain Apache Tribal Ct., 566 F.3d 842, 846 (9th Cir. 2009) ( .
