"The United States of America and the people of every State of which they are composed are each of them sovereign powers. The legislative authority of the whole is exercised by Congress under authority granted them in the common Constitution. The legislative power of each State is exercised by assemblies deriving their authority from the constitution of the State. Each is sovereign within its own province. The distribution of power between them presupposes that these authorities will move in harmony with each other. The members of the State and General Governments are all under oath to support both, and allegiance is due to the one and to the other. The case of a conflict between these two powers has not been supposed, nor has any provision been made for it in our institutions; as a virtuous nation of ancient times existed more than five centuries without a law for the punishment of patricide."
