Marshall pronounced the Fulton-Livingston monopoly inoperative so far as it concerned vessels enrolled under the Act of Congress to engage in the coasting trade; but in arriving at this very simple result his opinion takes the broadest possible range. At the very outset Marshall flatly contradicts Kent's proposition that the powers of the General Government, as representing a grant by sovereignties, must be strictly construed. The Constitution, says he, "contains an enumeration of powers expressly granted by the people to their government," and there is not a word in it which lends any countenance to the idea that these powers should be strictly interpreted. As men whose intentions required no concealment, those who framed and adopted the Constitution "must be understood to have employed words in their natural sense and to have intended what they said"; but if, from the inherent imperfection of language, doubts were at any time to arise "respecting the extent of any given power," then the known purposes of the instrument should control the construction put on its phraseology. "The grant does not convey power which might be beneficial to the grantor if retained by himself ... but is an investment of power for the general advantage in the hands of agents selected for the purpose, which power can never be exercised by the people themselves, but must be placed in the hands of agents or remain dormant." In no other of his opinions did Marshall so clearly bring out the logical connection between the principle of liberal construction of the Constitution and the doctrine that it is an ordinance of the American people.
