I have said that this doctrine cannot apply to the United States without implying those decisions respecting the common law which I have stated; because, should it be true as is contended that the constitutional definition of treason comprehends him who advises or procures an assemblage that levies war, it would not follow that such adviser or procurer might be charged as having been present at the assemblage.
If the adviser or procurer be within the definition of levying war, and independent of the agency of the common law do actually levy war, then the advisement of procurement is an overt act of levying war. If it be the overt action which he is to be convicted, then it must be charged in the indictment; for he can only be convicted on proof of the overt acts which are charged.
To render this distinction more intelligible let it be recollected, that although it should be conceded that since the statutes of William and Mary he who advises or procures a treason may, in England, be charged as having committed that treason by virtue of the common law operation, which is said so far as respects the indictment to unite the accessorial to the principal offence and permit them to be charged as one, yet it can never be conceded that he who commits one overt act under the statute of Edward can be charged and convicted on proof of another overt act.
If then procurement be an overt act of treason under the constitution, no man can be convicted for the procurement under an indictment charging him with actually assembling, whatever may be the doctrine of the common law in the case of an accessorial offender.[1520]
