Sure, easy enough. It is in the Nevada State Constitution: http://www.leg.state.nv.us/Const/NvConst.html
Under the section called Ordinance. Specificly paragraphs one and two. See item 3 of both paragraphs. In paragraph one, you will find the clause that cedes control of any US lands and in paragraph two you will see where it will not tax any such lands.
The Stazi thanks you for your unwavering support comrade. :-)
Third. That the people inhabiting said territory do agree and declare, that they forever disclaim all right and title to the unappropriated public lands lying within said territory, and that the same shall be and remain at the sole and entire disposition of the United States; and that lands belonging to citizens of the United States, residing without the said state, shall never be taxed higher than the land belonging to the residents thereof; and that no taxes shall be imposed by said state on lands or property therein belonging to, or which may hereafter be purchased by, the United States, unless otherwise provided by the congress of the United States.
You employer needs to feed you some new info to post. That land was appropriated as open range and is the basis of Bundy’s claim. That is all.
