Here is the opinion.

The court’s summary:

Reversing the district court’s summary judgment, the panel held that state and local governments lack the power to tax permanent improvements built on non-reservation land owned by the United States and held in trust for an Indian tribe pursuant to 25 U.S.C. § 465.

The panel held that pursuant to Mescalero Apache Tribe v. Jones, 411 U.S. 145 (1973), the exemption of trust lands from state and local taxation under § 465 extends to permanent improvements on such lands. The panel concluded that the fact that the improvements were owned by a limited liability company, rather than by the tribe itself, was irrelevant, as was the question whether the improvements constituted personal property under state law.
