City of Philadelphia v. New Jersey

MR. JUSTICE STEWART delivered the opinion of the Court.

A New Jersey law prohibits the importation of most "solid or liquid waste which originated or was collected outside the territorial limits of the State . . . ." In this case we are required to decide whether this statutory prohibition violates the Commerce Clause of the United States Constitution.

I

The statutory provision in question is ch. 363 of 1973 N. J. Laws, which took effect in early 1974. In pertinent part it provides:
"No person shall bring into this State any solid or liquid waste which originated or was collected outside the territorial limits of the State, except garbage to be fed to swine in the State of New Jersey, until the commissioner [of the State Department of Environmental Protection] shall determine that such action can be permitted without endangering the public health, safety and welfare and has promulgated regulations permitting and regulating the treatment and disposal of such waste in this State."


As authorized by ch. 363, the Commissioner promulgated regulations permitting four categories of waste to enter the State. Apart from these narrow exceptions, however, New Jersey closed its borders to all waste from other States.

Immediately affected by these developments were the operators of private landfills in New Jersey, and several cities in other States that had agreements with these operators for waste disposal. They brought suit against New Jersey and its Department of Environmental Protection in state court, attacking the statute and regulations on a number of state and federal grounds.

All objects of interstate trade merit Commerce Clause protection; none is excluded by definition at the outset. In Bowman and similar cases, the Court held simply that because the articles' worth in interstate commerce was far outweighed by the dangers inhering in their very movement, States could prohibit their transportation across state lines. Hence, we reject the state court's suggestion that the banning of "valueless" out-of-state wastes by ch. 363 implicates no constitutional protection. Just as Congress has power to regulate the interstate movement of these wastes, States are not free from constitutional scrutiny when they restrict that movement.

III

Although the Constitution gives Congress the power to regulate commerce among the States, many subjects of potential federal regulation under that power inevitably escape congressional attention "because of their local character and their number and diversity." In the absence of federal legislation, these subjects are open to control by the States so long as they act within the restraints imposed by the Commerce Clause itself. The bounds of these restraints appear nowhere in the words of the Commerce Clause, but have emerged gradually in the decisions of this Court giving effect to its basic purpose.


The opinions of the Court through the years have reflected an alertness to the evils of "economic isolation" and protectionism, while at the same time recognizing that incidental burdens on interstate commerce may be unavoidable when a State legislates to safeguard the health and safety of its people. Thus, where simple economic protectionism is effected by state legislation, a virtually per se rule of invalidity has been erected. The clearest example of such legislation is a law that overtly blocks the flow of interstate commerce at a State's borders.

The crucial inquiry, therefore, must be directed to determining whether ch. 363 is basically a protectionist measure, or whether it can fairly be viewed as a law directed to legitimate local concerns, with effects upon interstate commerce that are only incidental.

The purpose of ch. 363 is set out in the statute itself as follows:

"The Legislature finds and determines that . . . the volume of solid and liquid waste continues to rapidly increase, that the treatment and disposal of these wastes continues to pose an even greater threat to the quality of the environment of New Jersey, that the available and appropriate land fill sites within the State are being diminished, that the environment continues to be threatened by the treatment and disposal of waste which originated or was collected outside the State, and that the public health, safety and welfare require that the treatment and disposal within this State of all wastes generated outside of the State be prohibited."


This dispute about ultimate legislative purpose need not be resolved, because its resolution would not be relevant to the constitutional issue to be decided in this case. Contrary to the evident assumption of the state court and the parties, the evil of protectionism can reside in legislative means as well as legislative ends. Thus, it does not matter whether the ultimate aim of ch. 363 is to reduce the waste disposal costs of New Jersey residents or to save remaining open lands from pollution, for we assume New Jersey has every right to protect its residents' pocketbooks as well as their environment. And it may be assumed as well that New Jersey may pursue those ends by slowing the flow of all waste into the State's remaining landfills, even though interstate commerce may incidentally be affected. But whatever New Jersey's ultimate purpose, it may not be accomplished by discriminating against articles of commerce coming from outside the State unless there is some reason, apart from their origin, to treat them differently. Both on its face and in its plain effect, ch. 363 violates this principle of nondiscrimination.

The Court has consistently found parochial legislation of this kind to be constitutionally invalid, whether the ultimate aim of the legislation was to assure a steady supply of milk by erecting barriers to allegedly ruinous outside competition, or to create jobs by keeping industry within the State, or to preserve the State's financial resources from depletion by fencing out indigent immigrants. In each of these cases, a presumably legitimate goal was sought to be achieved by the illegitimate means of isolating the State from the national economy.

The New Jersey law at issue in this case falls squarely within the area that the Commerce Clause puts off limits to state regulation. On its face, it imposes on out-of-state commercial interests the full burden of conserving the State's remaining landfill space. It is true that in our previous cases the scarce natural resource was itself the article of commerce, whereas here the scarce resource and the article of commerce are distinct. But that difference is without consequence. In both instances, the State has overtly moved to slow or freeze the flow of commerce for protectionist reasons. It does not matter that the State has shut the article of commerce inside the State in one case and outside the State in the other. What is crucial is the attempt by one State to isolate itself from a problem common to many by erecting a barrier against the movement of interstate trade.

The New Jersey law blocks the importation of waste in an obvious effort to saddle those outside the State with the entire burden of slowing the flow of refuse into New Jersey's remaining landfill sites. That legislative effort is clearly impermissible under the Commerce Clause of the Constitution.

Today, cities in Pennsylvania and New York find it expedient or necessary to send their waste into New Jersey for disposal, and New Jersey claims the right to close its borders to such traffic. Tomorrow, cities in New Jersey may find it expedient or necessary to send their waste into Pennsylvania or New York for disposal, and those States might then claim the right to close their borders. The Commerce Clause will protect New Jersey in the future, just as it protects her neighbors now, from efforts by one State to isolate itself in the stream of interstate commerce from a problem shared by all. The judgment is Reversed.



MR. JUSTICE REHNQUIST, with whom THE CHIEF JUSTICE joins, dissenting.

A growing problem in our Nation is the sanitary treatment and disposal of solid waste.1 For many years, solid waste was incinerated. Because of the significant environmental problems attendant on incineration, however, this method of solid waste disposal has declined in use in many localities, including New Jersey. "Sanitary" landfills have replaced incineration as the principal method of disposing of solid waste. In ch. 363 of the 1973 N. J. Laws, the State of New Jersey legislatively recognized the unfortunate fact that landfills also present extremely serious health and safety problems. First, in New Jersey, "virtually all sanitary landfills can be expected to produce leachate, a noxious and highly polluted liquid which is seldom visible and frequently pollutes . . . ground and surface waters." The natural decomposition process which occurs in landfills also produces large quantities of methane and thereby presents a significant explosion hazard. Landfills can also generate "health hazards caused by rodents, fires and scavenger birds" and, "needless to say, do not help New Jersey's aesthetic appearance nor New Jersey's noise or water or air pollution problems."

The health and safety hazards associated with landfills present appellees with a currently unsolvable dilemma. Other, hopefully safer, methods of disposing of solid wastes are still in the development stage and cannot presently be used. But appellees obviously cannot completely stop the tide of solid waste that its citizens will produce in the interim. For the moment, therefore, appellees must continue to use sanitary landfills to dispose of New Jersey's own solid waste despite the critical environmental problems thereby created.

The question presented in this case is whether New Jersey must also continue to receive and dispose of solid waste from neighboring States, even though these will inexorably increase the health problems discussed above. The Court answers this question in the affirmative. New Jersey must either prohibit all landfill operations, leaving itself to cast about for a presently nonexistent solution to the serious problem of disposing of the waste generated within its own borders, or it must accept waste from every portion of the United States, thereby multiplying the health and safety problems which would result if it dealt only with such wastes generated within the State. Because past precedents establish that the Commerce Clause does not present appellees with such a Hobson's choice, I dissent.
