We do not conceal from ourselves the great responsibility which this duty devolves upon us. No questions so far reaching and pervading in their consequences, so profoundly interesting to the people of this country, and so important in their bearing upon the relations of the United States and of the several States to each other, and to the citizens of the states and of the United States, have been before this court during the official life of any of its present members. We have given every opportunity for a full hearing at the bar; we have discussed it freely and compared views among ourselves; we have taken ample time for careful deliberation, and we now propose to announce the judgments which we have formed in the construction of those articles, so far as we have found them necessary to the decision of the cases before us, and beyond that we have neither the inclination nor the right to go.”
