The line has not been so distinctly drawn as to avoid doubts in some cases of the exercise of power. Men of the best intentions and soundest views may differ in their construction of some parts of the Constitution; but there are others on which dispassionate reflection can leave no doubt. Of this nature appears to be the assumed right of secession. It rests, as we have seen, on the alleged undivided sovereignty of the States, and on their having formed in this sovereign capacity a compact which is called the Constitution, from which, because they made it, they have the right to secede. Both of these positions are erroneous, and some of the arguments to prove them so have been anticipated.
The States severally have not retained their entire sovereignty. It has been shown that in becoming parts of a nation, not members of a league, they surrendered many of their essential parts of sovereignty. The right to make treaties, declare war, levy taxes, exercise exclusive judicial and legislative powers, were all functions of sovereign power. The States, then, for all these important purposes, were no longer sovereign. The allegiance of their citizens was transferred in the first instance to the government of the United States; they became American citizens, and owed obedience to the Constitution of the United States, and to laws made in conformity with the powers vested in Congress. This last position has not been, and cannot be, denied. How, then, can that State be said to be sovereign and independent whose citizens owe obedience to laws not made by it, and whose magistrates are sworn to disregard those laws, when they come in conflict with those passed by another? What shows conclusively that the States cannot be said to have reserved an undivided sovereignty, is that they expressly ceded the right to punish treason—not treason against their separate power, but treason against the United States. Treason is an offense against sovereignty, and sovereignty must reside with the power to punish it. But the reserved rights of the States are not less sacred because they have for their common interest made the general government the depository of these powers. The unity of our political character (as has been shown for another purpose) commenced with its very existence. Under the royal government we had no separate character; our opposition to its oppression began as United Colonies. We were the United States under the Confederation, and the name was perpetuated and the Union rendered more perfect by the federal Constitution. In none of these stages did we consider ourselves in any other light than as forming one nation. Treaties and alliances were made in the name of all. Troops were raised for the joint defense. How, then, with all these proofs, that under all changes of our position we had, for designated purposes and with defined powers, created national governments—how is it that the most perfect of these several modes of union should now be considered as a mere league that may be dissolved at pleasure? It is from an abuse of terms. Compact is used as synonymous with league, although the true term is not employed, because it would at once show the fallacy of
