The plaintiffs in error were convicted in the court of quarter sessions of Cumberland county, New Jersey, at the May term, 1903, of the offense of unlawfully dredging upon certain oyster beds for the purpose of catching oysters, contrary to the statute enacted in that state. This judgment was affirmed in the court of errors and appeals of New Jersey and this writ of error seeks the reversal of that judgment.

Section 20 of the act of 1899, amended, Laws of 1901, p. 307, provides:

'Any person or persons who shall hereafter dredge upon or throw, take, or cast his oyster dredge, or any other instrument used for the purpose of catching oysters, upon any oyster bed or ground duly marked, buoyed, or staked up within the waters of the Delaware river, Delaware bay, and Maurice River cove, in this state, belonging to any other person, without the permission of the lessee or lessees thereof, shall be guilty of a misdemeanor and of the violation of the provisions of this act.'

It is the contention of the plaintiffs in error that this statute violates the right of free navigation, and undertakes to regulate interstate commerce in violation of § 8, article 1, of the Federal Constitution, and deprives the plaintiffs in error of rights secured by the 14th Amendment.

The power of the state to regulate the oyster industry, although the same is carried on under tidal waters in the state, is not contested, and could not successfully be. Smith v. Maryland, 18 How. 71, 15 L. ed. 269; McCready v. Virginia, 94 U. S. 391, 24 L. ed. 248; Manchester v. Massachusetts, 139 U. S. 240, 35 L. ed. 159, 11 Sup. Ct. Rep. 559.

The objection to the legality of the conviction from the standpoint of rights protected by the Federal Constitution, as urged upon our attention, rests upon the argument that § 20, amended as above quothed, permits the conviction of a person who shall take an oyster dredge or other instrument used for the purpose of catching oysters on any oyster bed or grounds within such navigable waters, thereby abridging and interfering with the right of free commerce with foreign nations, and among the several states. And it is argued that persons sailing over such waters, having an oyster-dredge aboard a boat, might be convicted of thus taking a dredge over such ground, in violation of the statute. Of this contention it is enough to say that in this case no such construction of the statute was made or enforced against the plaintiffs in error. Nor were they convicted because of any such state of facts; and it is well settled in this court that, because a state statute, when enforced in a state court against a class to which the party complaining does not belong, may work a deprivation of constitutional rights, that fact does not authorize the reversal of a judgment of a state court not enforcing the statute so as to deprive the party complaining of rights which are protected by the Federal Constitution. New York ex rel. Hatch v. Reardon, 204 U. S. 152-160, 51 L. ed. 415-422, 27 Sup. Ct. Rep. 188, and cases there cited.

An inspection of this record shows that the court of the indictment under which the plaintiffs in error were convicted charged them with unlawfully dredging, throwing, and casting dredges for the purpose of catching oysters upon certain leased lands, in violation of the statute.

The testimony offered on the part of the state tends to show that certain dredges were thus thrown and cast for the purpose of catching oysters upon leased lands belonging to one Allen.

On the part of the defense the witnesses testify that the dredges were not thus cast and used upon the lands in question. There was no pretense in the charge in the indictment, or in the testimony offered by the people, that a conviction could be had for the mere taking of a dredge over the leased lands. The conviction depended, both in the charge and in the testimony, upon establishing the fact that the plaintiffs in error thus illegally used the dredges.

It is contended that the plaintiffs in error might have been convicted for the mere sailing over the lands with a dredge aboard the boat, because of the following language in the court's charge:

'It then remains to be considered whether or not the defendants on that day dredged or threw, took or cast, a dredge or other instrument used for the purpose of catching oysters upon that ground. If they find that they did, then they should be convicted of illegal dredging, as charged in the first count of the indictment.'

But this excerpt must be read in connection with the rest of the charge, and it is perfectly apparent that it was not intended that the jury might convict for taking a dredge across the lands in sailing over them, under the indictment which made no mention of such taking, but distinctly counted upon the unlawful throwing and casting of the dredge upon the leased ground for the purpose of catching oysters. For immediately following the language quoted the learned judge goes on to say:

'Now, the state produces, bearing upon that question, the owner of the ground, and he testifies that on the day named in the indictment he, aboard of the Golden Light, with Captain Hilton, visited his ground; that as they approached it,—you will recall just how near they placed themselves, from their testimony,—as they approached it they saw these defendants aboard of a vessel called the Lee, maneuvering up and down this ground, No. 137, section B, of Captain Allen, and heaving their dredges thereon. Now, gentlemen, if you believe that testimony, if you believe that occurred as these witnesses for the state say it occurred, then, regardless of whether or not they got any oysters, if they were throwing their dredges there upon that ground they should be convicted under the first count of this indictment.

* * * * *

'Now, considering all of this testimony and any other testimony in the case, you ought to determine whether or not the defendants were there heaving their dredges and dredging upon this ground. And in endeavoring to ascertain the truth from this conflicting testimony it is but the dictate of common sense that you should consider whether any of the witnesses have a motive to testify falsely.'

It is therefore apparent that the possible construction of the statute in such manner as to convict plaintiffs in error of a crime in merely exercising their right to navigate interstate waters was not made essential to the determination of the case.

A conviction was had because of the use of a dredge upon leased lands, in violation of the New Jersey statute for the protection of the oyster industry. Against the statute, as thus enforced, no valid objection can be urged for want of power to pass or enforce it because of rights protected by the Federal Constitution.

Judgment of the Court of Errors and Appeals of New Jersey is affirmed.
