The boundary between tribal self-governance and state court authority is one of the most complex areas of U.S. property law. This conflict is particularly acute in cases involving Quiet Title Actions—a legal proceeding focused on determining clear ownership of land (in rem jurisdiction)—when the disputed land is owned by a federally recognized Indian tribe, even if that land is outside of a formal reservation.

Recent, defining decisions, notably from the Washington Supreme Court (following remand from the U.S. Supreme Court), have significantly clarified the limits of judicial power, establishing a critical precedent: Tribal Sovereign Immunity generally bars state courts from hearing quiet title claims against a tribe, even for non-reservation lands.

Understanding the Conflict: In Rem vs. Sovereign Immunity

The legal conflict stems from two distinct and powerful doctrines:

• Tribal Sovereign Immunity: This is the common law immunity from suit traditionally enjoyed by sovereign powers, which protects federally recognized tribes from being sued in any court (state or federal) unless Congress has expressly abrogated that immunity or the tribe has unequivocally waived it. The U.S. Supreme Court has repeatedly affirmed that this immunity extends to a tribe’s commercial activities and to its off-reservation property.

• In Rem Jurisdiction (Quiet Title): A Quiet Title Action is an in rem proceeding, meaning the court’s jurisdiction is focused on the property itself, rather than the individuals involved (which is called in personam jurisdiction). Historically, some state courts reasoned that since the lawsuit was technically against the property to settle its title, it could proceed without requiring the tribe’s direct participation, thus circumventing sovereign immunity.

The Precedent: Upper Skagit Indian Tribe v. Lundgren and Flying T Ranch v. Stillaguamish Tribe

The long-running case of Upper Skagit Indian Tribe v. Lundgren (and its progeny) brought this conflict to a head.

1. The Claim: A non-tribal landowner (Lundgren/Flying T Ranch) sought to quiet title to a strip of land owned by the Tribe, claiming title through adverse possession.

2. The Tribal Defense: The Tribe asserted sovereign immunity and moved to dismiss the case for lack of subject matter jurisdiction.

3. The Clarification: After initial confusion in the state courts, the U.S. Supreme Court vacated and remanded the case, instructing the lower court to address the sovereign immunity question directly. The subsequent Washington Supreme Court ruling in 2025 held that:

   • Immunity Bars Jurisdiction: Tribal sovereign immunity is a matter of subject matter jurisdiction. If the Tribe has not waived immunity and Congress has not abrogated it, the court lacks the power to hear the suit.

   • No In Rem Exception: The in rem nature of a quiet title action does not circumvent tribal sovereign immunity. The court cannot determine the ownership of the property in the tribe’s absence, as the tribe is an indispensable party whose rights would be directly prejudiced by the judgment.

   • No “Immovable Property” Exception: The state court explicitly rejected applying a common law “immovable property exception” (sometimes applied to foreign nations) to Indian tribes, stating that only Congress or the Tribe has the authority to limit the Tribe’s sovereign immunity.

The Scope of the Court’s Power

This precedent is significant for any entity, individual, or government agency involved in land transactions near properties owned by federally recognized tribes, even if the property is non-reservation, fee-patented land acquired by the tribe like any private entity.

The ruling establishes a clear boundary for jurisdiction based on the defendant and the Tribe’s position. If the Tribe is sued for Quiet Title (e.g., adverse possession), and sovereign immunity is asserted, the State court lacks subject matter jurisdiction and must dismiss the case. This is because the court cannot determine the ownership of the property in the Tribe’s absence. However, if the dispute involves non-tribal land where the Tribe is not a necessary party, the State court retains in rem jurisdiction over the property and can quiet title. Finally, the court has jurisdiction only if Tribal Immunity is explicitly waived or abrogated by Congress, allowing the quiet title action to proceed.

In effect, this means that absent a waiver, a non-tribal claimant seeking to quiet title to land against a tribe (even if based on long-term adverse possession) will be barred from court, ensuring the tribe can preserve its land holdings without being compelled to litigate in an external sovereign forum.

Conclusion

The clash between tribal sovereign immunity and in rem property proceedings like Quiet Title Actions is no longer ambiguous: sovereign immunity prevails. This precedent-setting clarification is vital for property owners, developers, and municipalities situated near tribally-owned lands, underscoring that litigation strategy in these disputes must begin and end with the threshold question of immunity. Attempting to pursue a quiet title action against a tribe without a clear waiver or Congressional abrogation is highly unlikely to succeed and risks significant legal expense.
