of the legislature to exercise that mode if it should be thought proper. The pretense, therefore, that the national legislature would not be at full liberty to submit all the civil causes of federal cognizance to the determination of juries, is a pretense destitute of all just foundation.
From these observations this conclusion results: that the trial by jury in civil cases would not be abolished; and that the use attempted to be made of the maxims which have been quoted, is contrary to reason and common sense, and therefore not admissible. Even if these maxims had a precise technical sense, corresponding with the idea of those who employ them upon the present occasion, which, however, is not the case, they would still be inapplicable to a constitution of government. In relation to such a subject, the natural and obvious sense of its provisions, apart from any technical rules, is the true criterion of construction.
Having now seen that the maxims relied upon will not bear the use made of them, let us endeavor to ascertain their proper use and true meaning. This will be best done by examples. The plan of the convention declares that the power of Congress, or, in other words, of the national legislature , shall extend to certain enumerated cases. This specification of particulars evidently excludes all pretension to a general legislative authority, because an affirmative grant of special powers would be absurd, as well as useless, if a general authority was intended.
In like manner the judicial authority of the federal judicatures is declared by the Constitution to comprehend certain cases particularly specified. The expression of those cases marks the precise limits, beyond which the federal courts cannot extend their jurisdiction, because the objects of their cognizance being enumerated, the specification would be nugatory if it did not exclude all ideas of more extensive authority.
These examples are sufficient to elucidate the maxims which have been mentioned, and to designate the manner in which they should be used.
