Here is the opinion:
This is a case about how California law applies to the delicate juncture of executive power, federalism, and tribal sovereignty. Under the federal Indian Gaming Regulatory Act (IGRA; 25 U.S.C. § 2701 et seq.), the United States Secretary of the Interior (Interior Secretary) may permit casino-style gaming on certain land taken into federal trust for an Indian tribe, so long as the Governor of the state where the land is located concurs. But nowhere in the California Constitution is the Governor granted explicit authority to concur in this cooperative-federalism scheme. We must decide whether the
Governor nonetheless has the authority to concur in the Interior Secretary’s determination to allow gaming on tribal trust land in California.
What we hold is that California law empowers the Governor to concur.
