Here is the opinion in MMG LLC v. Seminole Tribe of Florida Inc.
MMMG, LLC and Mobile Mike Promotions, Inc. appeal the involuntary dismissal of their complaint against a federal tribal corporation affiliated with the Seminole Tribe. We affirm the dismissal because the tribal corporation enjoyed sovereign immunity from suit, which was not effectively waived according to the procedure required in the corporation’s charter and bylaws.
Given the long history of exploitation of Native Americans, Congress has enacted statutes designed to protect tribes and tribal corporations. These statutes have been construed by federal and Florida courts as placing the onus on the non-tribal party to ensure that any waiver of sovereign immunity be executed in strict compliance with applicable tribal operating documents; common law doctrines such as apparent authority do not override the protection provided by federal law.
