Here is the opinion in White v. University of California.

From the court’s syllabus:

The panel affirmed the district court’s dismissal of an action under the Native Graves Protection and Repatriation Act on the basis that the affected tribes and their representatives were indispensable parties and could not be joined in the action.

The action concerned the “La Jolla remains,” two human skeletons discovered during an archaeological excavation on the property of the Chancellor’s official residence at the University of California-San Diego. The tribes claimed the right to compel repatriation of the La Jolla remains to one of the Kumeyaay Nation’s member tribes. Repatriation was opposed by the plaintiffs, University of California professors who wished to study the remains. The professors sought a declaration that the remains were not “Native American” within the meaning of NAGPRA, which provides a framework for establishing ownership and control of newly discovered Native American remains and funerary objects, as well as cultural items already held by certain federally funded museums and educational institutions.

The panel held that the plaintiffs had Article III standing to bring suit because if the La Jolla remains were repatriated,
the plaintiffs would suffer a concrete injury that was fairly traceable to the challenged action. In addition, this injury was likely to be redressed by a favorable decision.

The panel held that NAGPRA does not abrogate tribal sovereign immunity because Congress did not unequivocally express that purpose. The panel held that the “Repatriation Committee,” a tribal organization, was entitled to tribal sovereign immunity as an “arm of the tribe.” In addition, the Repatriation Committee did not waive its sovereign immunity by filing a separate lawsuit against the University or by incorporating under California law.

The panel held that the tribes and the Repatriation Committee were necessary parties under Federal Rule of Civil Procedure 19(a)(1) and were indispensable under Rule 19(b). In addition, the “public rights” exception to Rule 19 did not apply. Accordingly, the district court properly dismissed the action.

Dissenting, Judge Murguia agreed with the majority that the plaintiffs had Article III standing, that NAGPRA did not abrogate the sovereign immunity of the tribes, and that the Repatriation Committee was entitled to sovereign immunity. She would hold, however, that the Committee was not a necessary and indispensable party because it was neither necessary nor indispensable to resolution of the question whether the University properly determined that the La Jolla remains were Native American within the meaning of NAGPRA.
