This litigation has its genesis in a waste management scheme devised by the town fathers of Houlton, Maine (the Town). The appellants claim that Houlton’s plan — • under which the Town by contract designated a single firm as the exclusive hauler of residential waste within its borders, and enacted a flow-control ordinance directing all such waste either to be collected by that firm or to be brought to its transfer station — violates the Commerce Clause, the Takings Clause, the Contract Clause, and the town charter. The district court rejected these importunings. We affirm the judgment below (with a slight modification), but our reasoning differs from the district court’s in respect to the principal bone of contention — the Commerce Clause challenge.
I. BACKGROUND
As in many small towns across the nation, Houlton residents traditionally dealt with solid waste by depositing it in the town dump or engaging others to do so. On October 17, 1995, state environmental authorities closed the dump. In order to remain compliant with state law, the Town needed to fashion a new way for its residents to deal with solid waste. It thereupon issued a request for proposals (RFP), conducted an open competitive bidding process that resulted in the selection of a local firm (Andino, Inc.) as its exclusive contractor, agreed to provide that firm with a guaranteed trash quota for seven years, and enacted a flow-control ordinance (the 1995 Ordinance) that required all residential solid waste generated within the town limits to be taken to a local transfer site operated by Andino.
In New England, change does not come easily. Asserting that the 1995 Ordinance violated the Commerce Clause, David Con-don, a trash disposal operator, sued Andi-no and the Town. The federal district court preliminarily enjoined enforcement of the 1995 Ordinance,
see Condon v. Andino, Inc.,
The new plan has two components. The first is the 1997 Ordinance itself. The ordinance requires all generators of residential rubbish within the Town either to use Houlton’s chosen contractor to transport their trash, or to haul it themselves. See 1997 Ordinance § 10-507. Although the Town’s contractor is permitted to dispose of collected trash at any proper disposal site, residents who choose to self-haul are required to take their refuse to a repository designated by the Town Coun *182 cil. See id. § 10-504. The ordinance provides fines and other penalties for noncompliance. See id. § 10-503.
The contract between Andino and the Town constitutes the new scheme’s second component. The previous contract between these parties had included, inter alia, a failsafe clause whereby the Town agreed to negotiate with Andino in good faith to keep it as the Town’s contractor if a court of competent jurisdiction held the 1995 Ordinance invalid or unenforceable. Purporting to honor its commitment to renegotiate, the Town implemented the 1997 Ordinance by supplementing and amending the preexisting contract, granting Andino the exclusive right to collect third-party residential waste under the 1997 Ordinance, and designating its transfer station as the disposal site for self-haulers.
These modifications did not placate those who yearned for simpler times. Four plaintiffs combined to sue the Town in federal district court. They included Condon, two other local trash haulers (William Faulkner and Fred Spellman), and the Houlton Citizens’ Coalition (HCC), an unincorporated nonprofit association formed by Houlton residents. Invoking federal question jurisdiction, 28 U.S.C. § 1331' — there is no other readily apparent jurisdictional basis — the plaintiffs challenged the 1997 Ordinance under,
inter alia,
the Commerce Clause, the Takings Clause, and the Contract Clause. They also appended a supplemental state-law claim under the town charter. The district court rebuffed their attempt to restrain implementation of the 1997 Ordinance
pen-dente lite,
concluding that the plaintiffs were unlikely to prevalí on the merits.
See Houlton Citizens’ Coalition v. Town of Houlton,
II. STANDING
Before we consider the appellants’ substantive arguments, we pause to ponder a potential problem: the claim that the Coalition, an unincorporated nonprofit association that was formed, according to the uncontradicted affidavit of its president, specifically “to provide a forum for research, analysis, discussion and public education of civic policy issues related to the public administration of the Town of Houl-ton, Maine” and “to perform civic public service in this role,” lacks standing.
See United States v. AVX Corp.,
The Town brings some heavy artillery to this battlefield. Two respected courts recently have held that individual garbage generators lacked standing to challenge schemes similar to Houlton’s under the Commerce Clause.
See Ben Oehrleins & Sons & Daughter, Inc. v. Hennepin County,
*183
The HOC shares many attributes with the parties found to lack standing in
Ben Oehrleins
and
Washoe County.
It is made up of individual trash generators who complain that under the 1997 Ordinance they will be forced to contract with Andino, when previously they could patronize other haulers (presumably at lower prices or on more felicitous terms). Despite this parallelism, however, we need not decide whether we share the outlook of the
Ben Oehrleins
and
Washoe County
courts. It is a settled principle that when one of several co-parties (all of whom make similar arguments) has standing, an appellate court need not verify the independent standing of the others.
See Clinton v. City of New York,
Here, Faulkner, a co-plaintiff, satisfies both the constitutional requirements and the prudential conditions for standing. He has lost the business of his residential customers in Houlton; that injury can be traced directly to the Town’s neoteric waste management scheme; and the injury would be adequately redressed by equitable relief and/or damages against the Town. As a classic plaintiff asserting his own economic interests under the Commerce Clause—a constitutional provision specifically targeted to protect those interests—Faulkner avoids any concerns relative either to jus tertii,
see Worth v. Seldin,
We note, moreover, that Faulkner’s claim to standing is not damaged because he failed to allege that he hauled garbage out-of-state or planned to do so. In Commerce Clause jurisprudence, cognizable injury is not restricted to those members of the affected class against whom states or their political subdivisions ultimately discriminate.
See General Motors Corp. v. Tracy,
That ends this phase of our inquiry. Because Faulkner has standing to challenge the 1997 Ordinance, we need not decide whether the HCC has standing to mount a challenge in its own right.
III. ANALYSIS
The appellants find four fatal flaws in the Town’s waste management scheme: (1) it insults the dormant Commerce Clause; (2) it takes private property without just compensation; (3) it impermissibly burdens contracts; and (4) its implementation by the Town violates the municipal charter. Only the first of these contentions demands extended discussion.
The first order of business requires us to remark the underlying legal standard. This appeal emanates from an order granting summary judgment. We have written extensively about that procedural device,
see, e.g., McCarthy v. Northwest Airlines, Inc.,
A district court may enter summary judgment upon a showing “that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Fed.' R.Civ.P. 56(c). In this instance, the district court found that the Town had made
*184
such a showing and granted its motion for
brevis
disposition on all counts. We review orders for summary judgment de novo, considering the record and all reasonable inferences therefrom in the light most hospitable to the summary judgment loser.
See Mullin v. Raytheon Co.,
A. The Commerce Clause Challenge.
In terms, the Constitution empowers Congress “[t]o regulate Commerce ... among the several states.” U.S. Const, art I, § 8, cl. 3. Over time, courts have found a negative aspect embedded in this language—an aspect that prevents state and local governments from impeding the free flow of goods from one state to another. This has come to be known as the “dormant Commerce Clause.” The dormant Commerce Clause does not affect state or local regulations directly authorized by Congress,
see Southern Pac. Co. v. Arizona ex rel. Sullivan,
The case at hand involves the application of the dormant Commerce Clause to a municipal waste management scheme. While the issue is one of first impression in this circuit, we come upon the scene finding the legal landscape already considerably cluttered. The Supreme Court has dealt with quandaries of this general kind several times in the last decade.
See C & A Carbone, Inc. v. Town of Clarkstown,
After the closing of its municipal landfill and the entry of a consent decree with New York’s Department of Environmental Conservation, Clarkstown found itself in a situation similar to that of Houlton.
See Clarkstown,
The New York courts ruled that the flow-control ordinance passed constitutional muster.
See Town of Clarkstown v. C & A Carbone, Inc.,
The Court first addressed the threshold question of whether the challenged ordinance discriminated on its face against interstate commerce (as opposed to regulating commerce evenhandedly with only incidental effects on interstate commerce).
See id.
at 390,
Using these criteria, the Court adjudged Clarkstown’s flow-control ordinance discriminatory on its face; the ordinance achieved its goal of providing the refuse necessary to finance the Route 303 station “by depriving competitors, including out-of-state firms, of access to a local market.”
Id.
at 386,
In the jurisprudence of the dormant Commerce Clause, a finding of facial discrimination is almost always fatal.
Clarks-town
proved no exception. Though the municipality’s interests in the efficient processing and disposal of solid waste and in financing its transfer station were legitimate concerns, the Court abrogated the flow-control ordinance because those goals could have been pursued through nondiscriminatory alternatives.
See Clarkstown,
*186
Our sister circuits have glossed the lessons of
Clarkstown
somewhat differently. In
SSC Corp. v. Town of Smithtown,
On the same day it decided
Smithtown,
the Second Circuit also decided
USA Recycling, Inc. v. Town of Babylon,
The court held that Babylon’s scheme did not discriminate on its face against interstate commerce, but merely eliminated the commercial market for garbage collection services, substituting for it the town’s provision of those services through a private contractor. See id. at 1283. The court also held that Babylon’s grant of an exclusive franchise and free disposal rights to its chosen contractor constituted market participation, exempt from the requirements of the dormant Commerce Clause. See id. at 1288-89.
In the dim afterlight of
Clarkstown,
another court of appeals has spoken on the subject of flow control and the dormant Commerce Clause.
See Harvey & Harvey, Inc. v. County of Chester,
On appeal, the Third Circuit acknowledged that, under Clarkstown, a flow-control ordinance favoring a single in-state operator over all other in-state and out-of-state operators might be vulnerable to attack under the dormant Commerce Clause. See id. at 798. Still, the court observed that not all such ordinances would suffer such a fate. See id. Similarly, “[t]hat [an] ordinance requires the use of [a] selected *187 facility, thus prohibiting the use of non-designated facilities (which may be out of state), does not itself establish a Commerce Clause violation.” Id. Thus, although the grant of an exclusive contract to a local waste hauler/processor is suspect, it is not a per se violation of the dormant Commerce Clause. See id. at 801.
The Third Circuit then explained that, to secure a finding of discrimination vis-á-vis a flow-control scheme that excludes all out-of-state haulers and/or processors and most in-state haulers and/or processors, the challenger must show that those excluded did not have a fair opportunity to obtain the town’s custom. If the playing field is level for both in-state and out-of-state bidders, such parity ordinarily will satisfy the constitutional imperative. See id. at 802. Under this standard, “a local authority could choose a single provider— without impermissibly discriminating against inter-state commerce — so long as the selection process was open and competitive and offered truly equal opportunities to in- and out-of-state businesses.” Id. The court of appeals then asked the district court to reconsider Harvey & Harvey’s plaint in light of the newly articulated standard. See id. at 807.
Against this backdrop, we inquire whether the 1997 Ordinance enacted by the Houlton Town Council discriminates on its face against interstate commerce. Like Clarkstown’s ordinance, the challenged ordinance and the contract granted ancillary to it funnel all residential waste through a single contractor. Because of that similarity, the appellants chant the
Clarkstown
catechism, claiming that Houl-ton’s scheme “deprives out-of-state businesses of access to a local market,”
Clarkstown,
This last argument proved persuasive below. Following the
Babylon
court’s lead, the district judge considered the two parts of Houlton’s waste management scheme separately. Initially, he ruled that the 1997 Ordinance constituted market regulation and, like Babylon’s ordinance, served merely to eliminate the private sector from the garbage collection business.
See HCC I,
The judge also considered the Town’s contract with Andino and found that, under this contract, “Houlton is acting as a ‘buyer’ in the garbage collection, disposal, and processing markets, and enters those markets ‘with the same freedoms and subject to the same restrictions as a private party.’ ”
Id.
at 44 (quoting
Smithtown,
For two reasons, we are reluctant to place our imprimatur on the district court’s bifurcated analysis. First,
Smith-town
and
Babylon
are cutting-edge deci
*188
sions, and it is unclear to us whether or not the Supreme Court eventually will adopt their
ratio decidendi.
Second, and perhaps more important, although Houl-ton’s waste management scheme shares some features of the Smithtown and Babylon schemes, it differs significantly in requiring that those municipal residents who do not choose to tote their own garbage contract individually with the Town’s designated hauler for the purpose of removing residential refuse.
See
1997 Ordinance § 10-507(1). Moreover, even self-haulers are required to use a designated transfer station.
See id.
§ 10-504. The ordinance thus explicitly creates forced business transactions—an element that was present in
Clarkstown,
but lacking in the Second Circuit cases (both of which involved arrangements that avoided forced transactions by the simple expedient of appropriating tax dollars to fund waste management services). This distinction cannot be disregarded, for the Second Circuit’s market participation analysis in
Smith-tom
and its finding of nondiscrimination in
Babylon
were, at least to some extent, dependent on those communities’ expenditures of public funds in support of their contractual arrangements.
See Smithtown,
We need not probe this point too deeply, however, for the case at hand can be resolved in a more straightforward fashion. We do not interpret Clarkstown as explicating a broad-based ban on every flow-control ordinance that happens to be coupled with an exclusive contractual arrangement in favor of an in-state operator. To suggest that every such ordinance violates Clarkstown would stretch both Justice Kennedy’s language and the logic of the dormant Commerce Clause past the breaking point.
The core purpose of the dormant Commerce Clause is to prevent states and their political subdivisions from promulgating protectionist policies.
See, e.g., Camps Newfound/Owatonna,
It is a logical next step that when the Commerce Clause inquiry focuses on a state or local plan that culminates in an award of an exclusive contract to one of several aspirants (actual or potential), the process by which the contractor is chosen assumes great importance in determining the plan’s constitutionality
vel non. See Harvey & Harvey,
Applying this tenet, Houlton’s 1997 Ordinance does not flout the dormant Commerce Clause. Andino did not become the Town’s contractor in a backroom deal, cutting potential competitors off at the pass, but, rather, earned the Houlton contract through its successful completion of a well-advertised, fully competitive bidding process that was accessible to all who coveted the business. The Town issued a detailed RFP after holding a widely publicized meeting, open to all prospective bidders, at which such prospective bidders were able to comment on, and ask questions about, the project. The record contains no hint that the Town restricted the bid protocol to a particular class of bidders, shaped it to favor in-state operators, or slanted it in any way against out-of-state purveyors. 3 The RFP itself includes no terms that either give in-state operators a leg up or disadvantage their out-of-state rivals.
In point of fact, the RFP allows any bidder willing and able to haul and dispose of Houlton’s trash to submit a proposal. It does not lock bidders into using a particular transfer station; on the contrary, its terms permit the successful bidder to contract with whomever the bidder chooses (in-state or out-of-state) to process the garbage and effectuate disposal at any lawful site within or without the state. Furthermore, the RFP specifically notes that bidders may request deviations or file alternative proposals.
In response to the RFP, the Town received multiple bids. It awarded the contract to Andino—the low bidder. The contract’s seven-year term, though lengthy, does not seem excessive considering the relatively substantial commitment of equipment and other resources required on the successful bidder’s part—and nothing about this duration impacts out-of-state operators differently than their instate competitors. In short, this open and freely accessible bidding process ensured a level playing field for all interested parties and provided sufficiently broad market access to quell Commerce Clause concerns. Consequently, the Town’s garbage disposal scheme does not constitute a per se violation of the dormant Commerce Clause, but instead regulates commerce evenhandedly, with no more than incidental effects on interstate trade.
This brings us to the balancing test. Under this test, we must uphold the 1997 Ordinance “unless the burden imposed on [interstate] commerce is clearly excessive in relation to the putative local benefits.”
Pike,
B. Remaining Arguments.
The appellants’ three remaining arguments need not detain us. We note briefly why we regard two of them as unavailing, and why we conclude that the third should be left to the state courts.
1.
The Takings Clause.
The Fifth Amendment’s 'mandate that private property shall not be taken for public use
*190
without just compensation applies to the states and their political subdivisions through the Fourteenth Amendment.
See Chicago, Burlington & Quincy R.R. Co. v. Chicago,
Faulkner perceives a regulatory taking in this case because, after operating his trash-collecting business in Houlton for many years unfettered by municipal tethers, the passage of the 1997 Ordinance curbed his activities and dried up a significant income stream. But this argument swims against a powerful tide: courts steadfastly have rejected the proposition that the grant of an exclusive contract for refuse collection constitutes a taking vis-a-vis other (competing) trash haulers.
See California Reduction Co. v. Sanitary Reduction Works,
2.
The Contract Clause.
The Contract Clause declares that: “No State shall ... pass any ... Law impairing the Obligation of Contracts.” U.S. Const, art. I, § 10, cl. 1. Despite the majestic sweep of this language, the Contract Clause is not energized unless a contractual relationship exists, that relationship is impaired by a change in the law, and the resultant impairment is substantial.
See General Motors Corp. v. Romein,
In order to weigh the substantiality of a contractual impairment, courts look long and hard at the reasonable expectations of the parties. In this inquiry, it is especially important whether the parties operated in a regulated industry.
See Energy Reserves Group, Inc. v. Kansas Power & Light Co.,
Viewed through this prism, the question whether the impairment worked by the 1997 Ordinance meets the test of substantiality is close. We need not decide that close question, however, for even a state law that creates a substantial impairment does not transgress the Contract Clause as long as it is appropriate for, and necessary to, the accomplishment of a legitimate public purpose.
See Energy Reserves,
Upon finding a legitimate public purpose, the next step ordinarily involves ascertaining the reasonableness and necessity of the adjustment of contract obligations effected by the regulation to determine finally whether the regulation offends the Contract Clause.
See id.; Mercado-Boneta,
3. The Town Charter. The appellants do not dispute that the initial contract between Andino and the Town was secured through a fair and open competitive bidding process in which Andino was the successful low bidder. This process was mandated by, and fully conformed to, the requirement that “[a]ll purchases by the Town of property, services, and contract rights which exceed five thousand dollars ($5,000.00) shall be conducted by sealed, competitive bidding.” Houlton Town Charter § 512, ¶ 3. They assert, however, that the Town violated the charter when it renegotiated Andino’s contract to bring it in line with the 1997 Ordinance. 4 *192 The district court rejected this assertion, holding that there was no need for a new round of bidding, and that the renegotiated contract was valid. See HCC II, 11 F,Supp.2d at 111-12.
We think that this scenario presents a close question of state law — and one that the district court did not need to reach. After all, the district court had no independent jurisdiction over the town charter claim; and, although 28 U.S.C. § 1367 allows a district court that has jurisdiction over a series of federal claims to entertain related state-law claims that “form part of the same case or controversy,”
id.,
it does not oblige the court to continue with those claims if, prior to trial, it disposes of the federal claims. Where, as here, the federal claims upon which the court’s jurisdiction depends are resolved before trial, section 1367 confers upon the judge the authority to dismiss a supplemental state-law claim without prejudice.
See Rodriguez v. Doral Mortgage Corp.,
In this instance, the town charter claim is not only difficult, but also novel as a matter of state law. The litigation was in the early stages. Under the circumstances, we conclude that dismissal without prejudice clearly was the option of choice, and that the district court should not have ventured to adjudicate the town charter claim.
See Rodriguez,
IV. CONCLUSION
We need go no further. The Town of Houlton’s adoption of a flow-control ordinance, coupled with its grant of an exclusive hauling and disposal contract to a local contractor, does not discriminate on its face against interstate commerce because both in-state and out-of-state providers were allowed to compete for this contract on the same footing. Moreover, since any incidental effects that this waste management scheme may have on interstate commerce correspond to legitimate local interests in efficiency and public health, the plan does not violate the dormant Commerce Clause. By like token, it does not work an unconstitutional taking or impermissibly impugn private contracts. Finally, because the town charter claim depends entirely on state law, we think that the better course is to leave that claim to be litigated in the state courts (should the appellants choose to press it). We therefore direct the district court to modify its judgment to provide that the appellants’ claim under the Houlton Town Charter is dismissed without prejudice.
Affirmed as modified. Costs in favor of the appellee.
