A legal battle over who is and who is not a member in the Shakopee Mdwakanton Dakota tribe is still unresolved, four years after it began. The stakes in the fight have risen. The tribe's Mystic Lake Casino is so lucrative that tribe members now each receive some $700,000 a year in casino revenues. Some members say the tribal leadership is distributing those payments to people who don't qualify for membership, and withholding it from people who do. So far the federal government has declined to intervene. Minnesota Public Radio's John Biewen reports.
