Here is the opinion in Pauma Band of Luiseño Indians v. State of California.

From the court’s syllabus:

Affirming the district court’s summary judgment, the panel held that the Pauma Band of Luiseno Mission Indians was entitled to rescission of the 2004 Amendment to the 1999 Tribal-State Compact governing operation of Class III, or casino-style, gaming on Pauma’s land.

The panel held that the interpretation of a Compact license pool provision in Cachil Dehe Band of Wintun Indians of the Colusa Indian Cmty. v. Cal., 618 F.3d 1066 (9th Cir. 2010), applied, such that the State of California would be deemed to have misrepresented a material fact as to how many gaming licenses were available when negotiating with Pauma to amend its Compact. The panel held that, unlike a change in judicial interpretation of a statute or law, the doctrine of retroactivity does not apply to contracts. Once there has been a final judicial interpretation of an ambiguous contract provision, that is and has always been the correct interpretation from the document’s inception.

The panel held that the district court properly granted summary judgment on Pauma’s misrepresentation claim. The panel held that the district court awarded the proper remedy to Pauma by refunding $36.2 million in overpayments, even though the district court mislabeled the remedy as specific performance, rather than rescission and restitution for a voidable contract. The panel held that this equitable remedy fell within the State’s limited waiver of its sovereign immunity in the Compacts, and thus was not barred by the Eleventh Amendment.

On cross-appeal, the panel held that Pauma was not entitled to seek redress under the Indian Gaming Regulatory Act because the State and Pauma actually reached a gaming Compact.

Dissenting, Chief District Judge Jarvey wrote that the State did not commit the tort of misrepresentation by interpreting the Compact differently than a later court decision. He also wrote that, under the language of the Compact, the State did not waive its sovereign immunity with respect to this claim.
