I question a couple of 'facts' you present. You state, " (OHA)Trustees are now threatening to sue because the $1 million per year rent deal they originally signed isn’t good enough anymore."  I believe the original rent agreement was between UH and TMT Consortium. I don't think there ever was a "rent deal" between the TMT folks and OHA. 

   Also, according to http://www.maunakeaandtmt.org/investing-in-hawaii/:
"Paying $300,000 annual lease rent, which will increase incrementally to $1 million when it’s operational; 80% goes towards the stewardship of Maunakea and 20% to the Office of Hawaiian Affairs."  If TMT had ever become operational, the amount OHA would have received would have initially been $60,000, ranging to an upper limit of $200,000/yr  somewhere in the future, an amount far short of the $1,000,000 you state OHA would get for the "rent deal' with TMT folks. 

If I am incorrect in either or both of these points, I welcome correction from anyone, writer or readers.
