But at the time of the formation of the federal government, there were large areas of territory within its jurisdiction derived by cessions from the various states and from Great Britain under the treaty of peace ending the war of the Revolution, which were not included within the limits of any state, and provision was made in the constitution for the admission of new states out of such territory. This provision (Const. Art IV,§ 3,¶ 1) does not specify the conditions under which new states shall be admitted; consequently Congress may impose such conditions as it sees fit. It may require that certain fundamental provisions be incorporated into the constitution of the new state, that the state accept such boundaries as Congress may prescribe, and in general that any plan or policy which has the support of Congress be acceded to. But when a state has once been admitted, it is on a par, so far as power to regulate its internal affairs is concerned, with the other states, and it seems that it may by amendment change its constitution, regardless of any condition imposed by Congress. After admission a state is limited as to its powers only by the provisions of the constitution itself (Sands v. Manistee River Improvement Co.).
