Gibbons v. Ogden · ¶16

The 9th section of the 1st article declares, that “ no preference shall be given, by any regulation of commerce or revenue, to the ports of one State over those of another.” This clause cannot he understood as applicable to those laws only which are passed for the purposes of revenue, because it is expressly applied to commercial regulations; and the most obvious preference which can be given to one port over another, in regulating commerce, relates to navigation. But the subsequent part of the sentence is still more explicit. It is, : nor shall vessels bound to or from one-State, be obliged to enter, clear, or pay duties, in another.” These words have a direct reference to navigation.
