be formed by the junction of two or more States, or parts of States, without the consent of the legislatures of the States concerned, as well as of the Congress."
In the articles of Confederation, no provision is found on this important subject. Canada was to be admitted of right, on her joining in the measures of the United States; and the other COLONIES, by which were evidently meant the other British colonies, at the discretion of nine States. The eventual establishment of NEW STATES seems to have been overlooked by the compilers of that instrument. We have seen the inconvenience of this omission, and the assumption of power into which Congress have been led by it. With great propriety, therefore, has the new system supplied the defect. The general precaution, that no new States shall be formed, without the concurrence of the federal authority, and that of the States concerned, is consonant to the principles which ought to govern such transactions. The particular precaution against the erection of new States, by the partition of a State without its consent, quiets the jealousy of the larger States; as that of the smaller is quieted by a like precaution, against a junction of States without their consent.
This is a power of very great importance, and required by considerations similar to those which show the propriety of the former. The proviso annexed is proper in itself, and was probably rendered absolutely necessary by jealousies and questions concerning the Western territory sufficiently known to the public.
