This very narrow treatment of the points at issue, having to do with the mere lifeless machinery of the law, was strikingly criticised in the dissenting opinion afterwards read by Justice McLean, a part of which, by way of anticipation, may properly be quoted here. He denied that it was exclusively a Missouri question.

It involves a right claimed under an act of Congress and the Constitution of Illinois, and which cannot be decided without the consideration and construction of those laws.... Rights sanctioned for twenty-eight years ought not and cannot be repudiated, with any semblance of justice, by one or two decisions, influenced, as declared, by a determination to counteract the excitement against slavery in the free-States.... Having the same rights of sovereignty as the State of Missouri in adopting a constitution, I can perceive no reason why the institutions of Illinois should not receive the same consideration as those of Missouri.... The Missouri court disregards the express provisions of an act of Congress and the Constitution of a sovereign State, both of which laws for twenty-eight years it had not only regarded, but carried into effect. If a State court may do this, on a question involving the liberty of a human being, what protection do the laws afford?

Had the majority of the judges carried out their original intention, and announced their decision in the form in which Justice Nelson, under their instruction, wrote it, the case of Dred Scott would, after a passing notice, have gone to a quiet sleep under the dust of the law libraries. A far different fate was in store for it. The nation was then being stirred to its very foundation by the slavery agitation. The party of pro-slavery reaction was for the moment in the ascendant; and as by an irresistible impulse, the Supreme Court of the United States was swept from its hitherto impartial judicial moorings into the dangerous seas of polities.

Before Judge Nelson's opinion was submitted to the judges in conference for final adoption as the judgment of the court a movement seems to have taken place among the members, not only to change the ground of the decision, but also greatly to enlarge the field of inquiry. It is stated by one of the participants in that memorable transaction (Justice Campbell) that this occurred "upon a motion of Mr. Justice Wayne, who stated that the case had created public interest and expectation, that it had been twice argued, and that an impression existed that the questions argued would be considered in the opinion of the court." He further says that "the apprehension had been expressed by others of the court, that the court would not fulfill public expectation or discharge its duties by maintaining silence upon these questions; and my impression is, that several opinions had already been begun among the members of the court, in which a full discussion of the case was made, before Justice Wayne made this proposal."
The exact time when this movement was begun cannot now be ascertained. The motives which prompted it can be inferred by recalling contemporaneous political events. A great controversy divided public opinion, whether slavery might be extended or should be restricted. The Missouri Compromise had been repealed to make such an extension possible. The terms of that repeal were purposely couched in ambiguous language. Kansas and Nebraska were left "perfectly free to form and regulate their domestic institutions in their own way, subject only to the Constitution of the United States." Whether under the Constitution slavery could be excluded from the Federal Territories was affirmed by Northern and denied by Southern Democrats. Northern and Southern Democrats, acting together in the Cincinnati National Convention, had ingeniously avoided any solution of this difference.
A twofold interpretation had enabled that party to elect Mr. Buchanan, not by its own popular strength, but by the division of its opponents. Notwithstanding its momentary success, unless it could develop new sources of strength the party had only a precarious hold upon power. Its majority in the Senate was waning. In Kansas free-State emigration was outstripping the South in numbers and checkmating her in border strife. According to the existing relative growth in sectional representation and sectional sentiment, the balance of power was slowly but steadily passing to the North.
Out of this doubt and difficulty there was one pathway that seemed easy and certain. All the individual utterances from the Democratic party agreed that the meaning of the words "subject to the Constitution" was a question for the courts. This was the original compact between Northern and Southern Democrats in caucus when Douglas consented to repeal. Douglas, shorn of his prestige by his defeat for the Presidential nomination, must accept conditions from his successful rival. The Dred Scott case afforded the occasion for a decision. Of the nine judges on the Supreme Bench seven were Democrats, and of these five were appointed from slave-States. A better opportunity for the South to obtain a favorable dictum could never be expected to arise. A declaration by the Supreme Court of the United States that under the Constitution Congress possessed no power to prohibit slavery in the Federal Territories would by a single breath end the old and begin a new political era. Congress was in session and the political leaders were assembled at Washington. Political topics excluded all other conversation or thought. Politics reddened the plains of Kansas; politics had recently desecrated the Senate chamber with a murderous personal assault; politics contended greedily for the spoils of a new administration: politics nursed a tacit conspiracy to nationalize slavery. The slavery sentiment ruled society, ruled the Senate, ruled the Executive Mansion. It is not surprising that this universal influence flowed in at the open door of the national hall of justice—that it filtered through the very walls which surrounded the consulting-room of the Supreme Court.
