§ 18. Freedom of religion--Public lands--Indian lands--Uniformity of taxation--Territorial debt--Public schools--Federal reservations--Irrevocability. That we, the people of the state of South Dakota, do ordain:
First. That perfect toleration of religious sentiment shall be secured, and that no inhabitant of this state shall ever be molested in person or property on account of his or her mode of religious worship.
Second. That we, the people inhabiting the state of South Dakota, do agree and declare, that we forever disclaim all right and title to the unappropriated public lands lying within the boundaries of South Dakota; and to all lands lying within said limits owned or held by any Indian or Indian tribes, and that until the title thereto shall have been extinguished by the United States the same shall be and remain subject to the disposition of the United States, and said Indian lands shall remain under the absolute jurisdiction and control of the Congress of the United States; that the lands belonging to citizens of the United States residing without the said state, shall never be taxed at a higher rate than the lands belonging to residents of this state. That no taxes shall be imposed by the state of South Dakota on lands or property therein belonging to or which may hereafter be purchased by the United States, or reserved for its use. But nothing herein shall preclude the state of South Dakota from taxing as other lands are taxed any lands owned or held by any Indian who has severed his tribal relation and has obtained from the United States, or from any person a title thereto by patent or other grant save and except such lands as have been, or may be granted to any Indian or Indians under any act of Congress containing a provision exempting the lands thus granted from taxation, all such lands which may have been exempted by any grant or law of the United States, shall remain exempt to the extent, and as prescribed by such act of Congress.
Third. That the state of South Dakota shall assume and pay that portion of the debts and liabilities of the territory of Dakota as provided in this Constitution.
Fourth. That provision shall be made for the establishment and maintenance of systems of public schools, which shall be open to all the children of this state, and free from sectarian control.
Fifth. That jurisdiction is ceded to the United States over the military reservations of Fort Meade, Fort Randall and Fort Sully, heretofore declared by the president of the United States: provided legal process, civil and criminal, of this state shall extend over such reservations, in all cases of which exclusive jurisdiction is not vested in the United States, or of crimes not committed within the limits of such reservations.
These ordinances shall be irrevocable without the consent of the United States, and also the people of the said state of South Dakota, expressed by their legislative assembly.
