This natural and reasonable understanding of the term was supported by the authorities. Marshall then made specific reference to the opinions of a large number of British writers and judges, and of all American judges who had passed upon the question. In none of these, he asserted, had "the words 'levying war' ... received a technical different from their natural meaning"[1262]—that is, "the employment and exhibition of force."
Had he overruled all these opinions in the Bollmann-Swartwout case? Had he, in addition, reversed the natural interpretation of the Constitution which reason dictated? Surely not! Yet this was what he was now charged with having done.
But, said Marshall, "an opinion which is to overrule all former precedents, and to establish a principle never before recognized, should be expressed in plain and explicit terms." A mere implication was not enough. Yet this was all there was to justify the erroneous construction of his opinion in the case of Bollmann and Swartwout—"the omission of the court to state that the assemblage which constitutes the fact of levying war ought to be in force."[1263]
Marshall then went into an extended and minute analysis of his misunderstood opinion, and painfully labored to show that he then intended to say, as he now did say: that the act of levying war required "an assemblage in force," and not merely "a secret furtive assemblage without the appearance of force." The gathering "must be such as to prove that [war] is its object." If it was not "a military assemblage in a condition to make war, it was not a levying of war."[1264]
The indictment charged Burr with having levied war at a specific place and stated the exact manner in which the act had been done; this was necessary; otherwise the accused could not make adequate defense. So the indictment "must be proved as laid"; otherwise "the charge of an overt act would be a mischief instead of an advantage to the accused," and would lead him from the true cause and nature of the accusation instead of informing him respecting it.[1265]
The Government insisted that, although Burr "had never been with the party ... on Blennerhassett's island, and was, at the time, at a great distance and in a different state,... he was yet legally present, and therefore may properly be charged in the indictment as being present in fact." Thus, the question arose "whether in this case the doctrine of constructive presence can apply." In answering it, John Marshall ended the contention that so cruel a dogma can ever be applied in America. This achievement was one of his noblest services to the American people.[1266]
Again an imposing array of precedents was examined. "The man, who incites, aids, or procures a treasonable act," is not, merely on that account, "legally present when that act is committed."[1267] Of course, other facts might require that a man should be considered to be present although really absent; for example, if he were on the way there for the purpose of taking part in the specific act charged, or if he were stationed near in order to coöperate with those who actually did the deed, he would be of them and associated with them in the perpetration of that particular act.[1268] But otherwise he could not be said to be present.
If this were not so, then a man levying war in one part of the country might be construed to be present at and taking part in hostilities at the most distant point of the Republic—a participator in "every overt act performed anywhere"; and he would be liable to trial and conviction "in any state on the continent where any overt act has been committed" by anybody. "He may be proved to be guilty of an overt act laid in the indictment in which he had no personal participation, by proving that he advised it, or that he committed other acts."[1269]
If Burr were guilty of treason in connection with the assemblage on Blennerhassett's island, it was only because Burr procured the men to meet for the purpose of levying war against the United States. But the fact that he did procure the treasonable assemblage must be charged in the indictment and proved by two witnesses, precisely as must actual physical presence—since the procuring of the assemblage takes the place of presence at it. "If in one case," declared Marshall, "the presence of the individual make the guilt of the assemblage his guilt, and in the other case the procurement by the individual make the guilt of the assemblage his guilt, then presence and procurement are equally component parts of the overt act, and equally require two witnesses."[1270]
Neither presence nor procurement could, therefore, be proved by collateral testimony: "No presumptive evidence, no facts from which presence may be conjectured or inferred will satisfy the constitution and the law." And "if procurement take the place of presence and become part of the overt act, then no presumptive evidence, no facts from which the procurement may be conjectured, or inferred, can satisfy the constitution and the law.
