The Court ultimately upheld the constitutionality of New Jersey's law. With regards to the Commerce Clause, Justice Washington found that Congress's power to regulate commerce "does by no means impair the right of the state government to legislate upon all subjects of internal police within their territorial limits ... even although such legislation may indirectly and remotely affect commerce, provided it do not interfere with the regulations of congress upon the same subject." He cited
Gibbons v. Ogden in this reasoning, providing verbatim the list of allowed state laws mentioned in that decision: "inspection, quarantine, and health laws; laws regulating the internal commerce of the state; laws establishing and regulating turnpike roads, ferries, canals, and the like." Washington also argued that the New Jersey law does not affect articles of commerce directly, by making a crucial distinction: "the law does not inhibit the buying and selling of oysters after they are lawfully gathered, and have become articles of trade; but it forbids the removal of them from the beds in which they grow." As state laws that regulate the manner of taking of articles of trade such as "[p]aving stones, sand, and many other things" could not possibly be said to be unconstitutional, the Justice concluded that the New Jersey law did not fall afoul of the Commerce Clause. Next, Washington treated the Privileges and Immunities Clause issue. The perhaps most-cited aspect of
Corfield v. Coryell is Justice Washington's listing of the "privileges and immunities" enjoyed by citizens of the United States: Thus, Washington concluded that the right to harvesting oysters, not being included in the list of these fundamental privileges and immunities of citizens, was not bound to be extended to all non-state citizens. The opinion concluded that "[the right] of fishing belongs to all the citizens or subjects of the state" who are "exclusively entitled to the use of it." Washington also added a practical consideration for this distinction: although the state's supply of oysters "may be abundantly sufficient for the use of the citizens of that state," its supply might be "totally exhausted and destroyed" if citizens from all other states were equally entitled to make use of them. For the argument that the law violates the judicial power of the United States in cases of admiralty and maritime jurisdiction (enumerated in Article III Section II), the opinion states that this power was likely still vested in the States, not in the national government. Then, the opinion demonstrates how the area in question is within the jurisdiction of both New Jersey and Cumberland County. Finally, the opinion indicates that an action of trespass from the owner of the vessel is not warranted, because as the vessel was rented out to the plaintiff, the owner of the vessel cannot pass such an action. ==Influence on Fourteenth Amendment==
