But it isn't an obvious eminant domain.
1.>We don't know how that region came to be Federation
2.>The Ba'ku settled on that world prior to the Federation being founded.
3.>If the Ba'ku settled on that world prior to anyone claiming it fell within their sphere of influence then eminant domain can't apply.
Is there a specifc line in the film that says that region belonged to another power prior to the Ba'ku setteling on the planet?
