Rich.  Sorry, but there is little tribal land, even in remote villages.  I haven't read the opinion ,but it isn't clear to me how a tribal government could enforce anything on lands that it does not own.  Every village is a mix of private, ANCSA village and regional corporation lands and some tribal lands.  I don't believe that tribal government jurisdiction could extend beyond lands under its ownership.  It's a complex issue that needs to be better defined.
