Well, taking a claim from a lease is a very old and dubious tactic of governmental bodies going back as far as anyone can remember. We can go so far back to Old Earth, if you like. The American Revolution during those times produced a wonderful document that serves as quite a model for what I believe most Clans would like to see instituted on Rubi-Ka. Perhaps that is only my wishful thinking taking place here, and there were many governments that were ruled by their own people through representatives on the planet later on. But those crazy rebels, they had something going there.
They were most assuredly a loose confederation of "states" that formed a federated entity whose sole purpose was to set up ways in which they would cooperate and ways that they would subject themselves to each others rules. I don't want to get into more details here, but one of the earlier problems that they found when they were writing up that old venerable document called The Constitution was that there were two schools of thought about how to interpret the powers given within.
The side that I tended to favor (although certain aspects of this side made me cringe) was the side defended by and large by the veritable demigod named Thomas Jefferson. He stated that the only powers that you were to use were the powers that were specifically granted in that document, and all others would require amendments to that document. Meaning, that you can't just do whatever the hell you want to do, it has to spell it out there in black and white that you are allowed to do something before you have the authority to do so.
Now on the other side (the one I think that would represent your interpretation) was most vociferously represented by one of the other demigods named Alexander Hamilton. His views of the powers that the federal entity had were implied as just and right for any nation state.
During Jefferson's administration as President, he was faced with a conundrum that the Constitution did not forsee, which was Napoleon. Jefferson had wished to purchase the one thing that would shut off the interior of his nation like a light switch, which was the mouth of the Mississippi River. That spot was held by the French and was located at the port of New Orleans. Jefferson wanted this land so that he could put troops there and guarentee free and safe passage of merchants and materials through the river (I think he wanted Florida also, but I digress). Napoleon, in the most amazingly daft counteroffer in the world, wanted to divest France of the entire Louisiana Purchase. This put Jefferson in a bit of a bind.
As a strict constructionist, he knew that the act of acquiring empire was not written as one of the powers he had. So he balked at the offer for quite sometime, making Napoleon very agitated and also making him have second thoughts about the whole deal (which by all rights he should have had in the first place). Jefferson's greatest political opponent, Mr. Hamilton, waved off the perplexing issue Jefferson was wrestling with. Mr. Hamilton said that "it's implied that you may acquire empire, that's what nations do" (to paraphrase his views). Jefferson was having none of that. He wanted an amendment for this one time deal, and eventually this purchase was made and this great man doubled the "Empire for Liberty" (Jefferson's words) with the stroke of a pen.
Now, how it relates. Trgeorge hits the nail squarely on the head and drives that nail right into the wood. The rights to mine were not the rights to govern. That is not how I read the lease agreement. I read the lease agreement as to be allowed to exploit the natural resources of the planet, and not to create your totalitarian nightmare ruled by a dictator/demagogue, free to do whatever he felt like doing, just as long as the bottom line was secure. It was this governmental faux pas that eventually created the conflict we currently find ourselves embroiled in.
Now, as my little history lesson will conclude, "forcing you to conform to our vision of how a government should work" would not only have been more wise, but would have spared more lives than any of us can possibly fathom, and it also would have allowed you to exploit this planet's natural resources and you would not have had to fire a single shot to do it, as we would all still be Omni-Tek employees and would have supported Mr. Ross. As the corporate CEO, and not as "Prime Minister' or whatever he fancies himself as (I personally think he thinks he is Caeser Augustus, but again I digress).
