Decision
In the court's opinion, Justice Clark said: "In thus erecting an economic barrier protecting a major local industry against competition from without the state, Madison plainly discriminates against interstate commerce. This it cannot do, even in the exercise of its unquestioned power to protect the health and safety of the people, if reasonable nondiscriminatory alternatives... are available".
The fact that in-state producers were also discriminated against was not found to be relevant to the fact that it discriminated against interstate commerce.
Justices Vinson, Reed, Frankfurter, Jackson, and Burton concurred.
Justices Black, Douglas and Minton dissented on the grounds that any imposition on commerce is minor compared to the city's need to insure their milk is healthy without burdening their inspectors.
The Dormant Commerce Clause, or Negative Commerce Clause, in American constitutional law, is a legal doctrine that courts in the United States have inferred from the Commerce Clause in Article I of the US Constitution. The primary focus of the doctrine is barring state protectionism. The Dormant Commerce Clause is used to prohibit state legislation that discriminates against, or unduly burdens, interstate or international commerce. Courts first determine whether a state regulation discriminates on its face against interstate commerce or whether it has the purpose or effect of discriminating against interstate commerce. If the statute is discriminatory, the state has the burden to justify both the local benefits flowing from the statute and to show the state has no other means of advancing the legitimate local purpose.
The Commerce Clause describes an enumerated power listed in the United States Constitution. The clause states that the United States Congress shall have power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes". Courts and commentators have tended to discuss each of these three areas of commerce as a separate power granted to Congress. It is common to see the individual components of the Commerce Clause referred to under specific terms: the Foreign Commerce Clause, the Interstate Commerce Clause, and the Indian Commerce Clause.
City of Philadelphia v. New Jersey, 437 U.S. 617 (1978), was a case in which the Supreme Court of the United States held that states could not discriminate against another state's articles of commerce.
Kassel v. Consolidated Freightways Corp., 450 U.S. 662 (1981), was a United States Supreme Court case involving the application of the Dormant Commerce Clause to an Iowa state statute restricting the length of tractor-trailers.
United Building & Construction Trades Council v. Mayor and Council of Camden, 465 U.S. 208 (1984), was a case in which the Supreme Court of the United States held that a city can pressure private employers to hire city residents, but the same exercise of power to bias private contractors against out-of-state residents may be called into account under the Privileges and Immunities Clause of Article Four of the United States Constitution.
C&A Carbone, Inc. v. Town of Clarkstown, New York, 511 U.S. 383 (1994), was a case before the United States Supreme Court in which the plaintiff, a private recycler with business in Clarkstown, New York, sought to ship its non-recyclable waste to cheaper waste processors out-of-state. Clarkstown opposed the move, and the company then brought suit, raising the unconstitutionality of Clarkstown's "flow control ordinance," which required solid wastes that were not recyclable or hazardous to be deposited at a particular private company's transfer facility. The ordinance involved fees that were above market rates. The Supreme Court sided with the plaintiff, concluding that Clarkstown's ordinance violated the Dormant Commerce Clause.
Southern Pacific Company v. Arizona, 325 U.S. 761 (1945), was a United States Supreme Court case in which the Court held that the Arizona Train Limit Law of 1912, which prohibited passenger trains with more than fourteen cars and prohibited freight trains with more than seventy cars, placed an unconstitutional burden on interstate commerce. The Court held that the law imposed a burden far greater than necessary to achieve Arizona's legitimate interest in lowering the rate of train accidents. This case is part of the Court's so-called negative commerce clause jurisprudence.
United Haulers Ass'n v. Oneida-Herkimer Solid Waste Management Authority, 550 U.S. 330 (2007), was a United States Supreme Court case about interstate commerce. Chief Justice John Roberts wrote the opinion of the Court, holding that New York county ordinances forcing private waste management companies to deliver waste to a public facility did not discriminate against interstate commerce. Justice Samuel Alito wrote a dissent.
West Lynn Creamery, Inc. v. Healy, 512 U.S. 186 (1994), was a United States Supreme Court case.
Minnesota v. Clover Leaf Creamery Co., 449 U.S. 456 (1981), was a United States Supreme Court case which found no violation of the equal protection or commerce clauses in a Minnesota state statute banning retail sale of milk in plastic nonreturnable, nonrefillable containers, but permitting such sale in other nonreturnable, nonrefillable containers.
Bibb v. Navajo Freight Lines, Inc., 359 U.S. 520 (1959), is a United States Supreme Court case in which the Court held that the Illinois law requiring trucks to have unique mudguards was unconstitutional under the Commerce clause.
Breard v. City of Alexandria, 341 U.S. 622 (1951), was a United States Supreme Court case, which held that door-to-door solicitation could be restricted without violating the First Amendment or the Dormant Commerce Clause.
Exxon Corp. v. Governor of Maryland, 437 U.S. 117 (1978), was a case in which the Supreme Court of the United States upheld a Maryland law prohibiting oil producers and refiners from operating service stations within its borders. The challengers, including Exxon, claimed that the law violated the Dormant Commerce Clause. Justice Stevens wrote for the majority, which disagreed with Exxon et al.: "Since Maryland's entire gasoline supply flows in interstate commerce and since there are no local producers or refiners, such claims of disparate treatment between interstate and local commerce would be meritless." Exxon challenged the Maryland statute in Circuit Court which ruled the statute invalid. The Maryland Court of Appeals reversed the ruling.
Smith v. California, 361 U.S. 147 (1959), was a U.S. Supreme Court case upholding the freedom of the press. The decision deemed unconstitutional a city ordinance that made one in possession of obscene books criminally liable because it did not require proof that one had knowledge of the book's content, and thus violated the freedom of the press guaranteed in the First Amendment. Smith v. California continued the Supreme Court precedent of ruling that questions of freedom of expression were protected by the Due Process Clause of the Fourteenth Amendment from invasion by state action. It also established that in order for one to be criminally liable for possession of obscene material, there must be proof of one's knowledge of the material. It described that by requiring booksellers to know the contents of all of the books that they sell, this would lead to the government compelling booksellers to self-censor thereby restricting the public's access to books which the State could not constitutionally suppress directly.
United Gas Pipe Line Co. v. Ideal Cement Co., 369 U.S. 134 (1962), is a United States Supreme Court case which vacated a lower appellate court decision, holding that federal courts should abstain from ruling on the constitutionality of a state tax issue that state courts should determine.
Reeves, Inc. v. Stake, 447 U.S. 429 (1980), was a United States Supreme Court case in which the Court held that individual states, when acting as producers or suppliers rather than as market regulators, may discriminate preferentially against out-of-state residents. This "market participant" doctrine is an exception to the so-called negative commerce clause, which ordinarily deems state regulations invalid where they discriminate against interstate commerce in favor of intrastate commerce for the purpose of economic protectionism.
Comptroller of the Treasury of Maryland v. Wynne, 575 U.S. 542 (2015), is a 2015 U.S. Supreme Court decision that applied the Dormant Commerce Clause doctrine to Maryland's personal income tax scheme and found that the failure to provide a full credit for income taxes paid to other states was unconstitutional.
Article I, § 10, clause 2 of the United States Constitution, known as the Import-Export Clause, prevents the states, without the consent of Congress, from imposing tariffs on imports and exports above what is necessary for their inspection laws and secures for the federal government the revenues from all tariffs on imports and exports. Several nineteenth century Supreme Court cases applied this clause to duties and imposts on interstate imports and exports. In 1869, the United States Supreme Court ruled that the Import-Export Clause only applied to imports and exports with foreign nations and did not apply to imports and exports with other states, although this interpretation has been questioned by modern legal scholars.
Portland Pipe Line Corp. v. City of South Portland is a lawsuit filed on February 6, 2015, in the United States District Court for the District of Maine. It involved a pipeline operator's challenge to South Portland, Maine's local ordinance prohibiting loading crude oil onto tankers and the construction of new structures for that purpose on the grounds that it violates the dormant Commerce Clause and Foreign Commerce Clause of the United States Constitution.
National Pork Producers Council v. Ross, 598 U.S. 356 (2023), was a United States Supreme Court case related to the Dormant Commerce Clause.
