"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."
