§ 26.   Power inherent in people--Alteration in form of government--Inseparable part of Union. All political power is inherent in the people, and all free government is founded on their authority, and is instituted for their equal protection and benefit, and they have the right in lawful and constituted methods to alter or reform their forms of government in such manner as they may think proper. And the state of South Dakota is an inseparable part of the American Union and the Constitution of the United States is the supreme law of the land.
