A judge has ruled that members of a South Florida Indian tribe must pay federal income taxes in a decision that could cost other tribe members millions of dollars.

The decision Friday by U.S. District Judge Cecilia M. Altonaga in Miami involves the 600-member Miccosukee tribe, which has a reservation in the Everglades and a gambling casino west of Miami. Ruling in the case of tribe member Sally Jim, Altonaga found that distribution of casino profits was not exempt from U.S. income taxes.
