MADSEN, J.— Under federal common law, Indian tribes may be sued only under two circumstances: when a tribe waives its sovereign immunity or when Congress unequivocally abrogates tribal sovereign immunity. Here, Flying T Ranch (Flying T)

filed suit in Snohomish County Superior Court to quiet title to nonreservation land purchased by the Stillaguamish Tribe of Indians (Tribe). Flying T contends it had

No. 103430-0

acquired that land through adverse possession prior to the Tribe’s purchase. The superior court dismissed the case with prejudice based on the Tribe’s sovereign immunity.

The primary issue before us is a matter of first impression: whether a common law immovable property exception waives tribal sovereign immunity. The Court of Appeals held that tribal sovereign immunity is not subject to an immovable property exception absent a clear waiver by Congress or the tribe itself. Congress has not clearly indicated its intent to abrogate tribal sovereign immunity here; therefore, we affirm the Court of Appeals.

FACTS

The Stillaguamish Tribe of Indians is a federally recognized Indian tribe. In 2021, the Tribe purchased a parcel of land located along the Stillaguamish River via statutory warranty deed. The Tribe purchased its parcel utilizing state and federal funding from a conservation grant from the National Oceanic and Atmospheric Administration, through the Washington State Recreation and Conservation Office. The main purpose of the grant is to protect the land in perpetuity with a deed of right for salmon recovery.

Upon acquiring title, the Tribe designated the plot as “conservation” land. Clerk’s Papers at 86. The Tribe’s interest in the land has been specifically for protecting the riparian habitat necessary for salmon, which is in turn tightly connected to the Tribe’s treaty right to fish. As the Stillaguamish River salmon runs face extinction, so do many aspects of the Tribe’s culture, community, and treaty reserved rights. By using these parcels as conservation land to protect and restore salmon in the Stillaguamish River, the

No. 103430-0

Tribe seeks to preserve their way of life. Prior to purchase, the land had not been part of any reservation.

Flying T, a Washington corporation domiciled in Snohomish County, has owned a parcel of land running adjacent to that of the Tribe’s and county’s parcels since 1991.

Snohomish County had acquired its portion of the disputed parcel of land along the Stillaguamish River in 1995. The land was privately owned prior to the county acquiring it.

In 2022, Flying T filed a complaint against Snohomish County and the Tribe in Snohomish County Superior Court, seeking to quiet title to a narrow strip of the two parcels of land described above by adverse possession. Id. at 84-85. Flying T contends that since at least 1962, it and its predecessors in interest have had continuous and exclusive possession over a narrow strip of both the Tribe’s and county’s parcels of land by and through their maintenance of a fence, which served to mark the boundary line, and their use of the land to graze and keep livestock. It contends that their possession has been actual, uninterrupted, open, notorious, exclusive, and hostile to any claim of right by all others.

The Tribe moved to dismiss pursuant to CR 12(b)(1)-(3), (6), and (7), based on tribal sovereign immunity. Before the court ruled on the motion to dismiss, Snohomish County conveyed its portion of the disputed parcel of land to the Tribe, and thus the Tribe acquired ownership of the entire disputed parcel. The superior court entered an order

No. 103430-0

granting the Tribe’s motion to dismiss. Flying T moved for reconsideration, which was denied.

Flying T appealed, seeking direct discretionary review in this court. We denied the motion and transferred the case to the Court of Appeals. 1 Flying T argued that although tribes enjoy common law sovereign immunity, the scope of that immunity is limited by the common law immovable property exception, and since adverse possession claims affect title to real property, Washington superior courts have in rem jurisdiction over nonreservation land within state boundaries, even if owned by a tribe.

The Court of Appeals rejected Flying T’s arguments and affirmed the superior court’s dismissal of the quiet title action. 2 It concluded that “a foreign sovereign enjoys immunity as directed by the political branches of government and would not face process directed by the judiciary alone. When the Tribe is afforded immunity equal to a foreign

1 After filing a notice of appeal, but before filing its statement of grounds for direct review, Flying T moved in the trial court to clarify whether the order dismissing the claims against the Tribe was a final, appealable order since Snohomish County was not dismissed from the suit. In April 2023, the trial court signed a new order stating that Snohomish County was dismissed from the action and that all claims against the Tribe were dismissed with prejudice. Flying T then filed a motion to clarify appealability or to extend time to file an amended notice of appeal in this court and filed an amended notice of appeal. The Tribe filed a motion to dismiss the appeal or any discretionary review based on Flying T’s failure to timely appeal from the new April order. We transferred the case along with the motion to clarify and the motion to dismiss to the Court of Appeals. 2 The parties dispute the Court of Appeals’ holding. The Tribe states that the Court of Appeals held that there is no common law immovable property exception to tribal sovereign immunity, that cases finding an in rem exception to tribal sovereign immunity are no longer good law, and that only Congress can abrogate tribal sovereign immunity. Flying T states that the Court of Appeals correctly held that the immovable property exception should apply to tribes acquiring nonreservation land but erred when it deferred to Congress. The Court of Appeals in essence stated that even if a common law immovable property exception exists, it should not extend to tribal sovereign immunity absent some direction from Congress. See Flying T Ranch, Inc. v. Stillaguamish Tribe of Indians, 31 Wn. App. 2d 343, 359-62, 549 P.3d 727 (2024).

sovereign, it may be sued over its objection only when allowed by Congress, and to hold otherwise would unfaithfully lessen its immunity in comparison to that traditionally enjoyed by sovereign powers.” Flying T Ranch, Inc. v. Stillaguamish Tribe of Indians, 31 Wn. App. 2d 343, 346, 549 P.3d 727 (2024). The court stated that Flying T has not shown “any history of the judiciary invoking the immovable property exception against a foreign nation to disallow foreign sovereign immunity without regard to the direction of the political branches.” Id. at 358. It also noted that the codification of the Foreign Sovereign Immunities Act (FSIA) did not support application of a common law immovable property exception here absent congressional direction. Thus, Congress must act to limit tribal immunity. Id. at 371.
