Dominic:  You've done your homework, but you're still playing by the Sealaska board's rules ... which is that they run it as a family (majority clans/shareholders) business, shutting out non-family (minority clans/shareholders) from meaningful participation.  If you decide to take it to court, you may have to exhaust all state remedies first, unless you can make a credible showing that the suit involves only federal law and legislation.  Some lawyer out there just may take the suit "pro bono" ... since it could enhance their reputation, or advance their own interests.
