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.
Heart of Atlanta Motel, Inc. v. United States, 379 U.S. 241 (1964), was a landmark decision of the Supreme Court of the United States holding that the Commerce Clause gave the U.S. Congress power to force private businesses to abide by Title II of the Civil Rights Act of 1964, which prohibits discrimination on the basis of race, religion, or national origin in public accommodations.
A.L.A. Schechter Poultry Corp. v. United States, 295 U.S. 495 (1935), was a decision by the Supreme Court of the United States that invalidated regulations of the poultry industry according to the nondelegation doctrine and as an invalid use of Congress' power under the Commerce Clause. This was a unanimous decision that rendered parts of the National Industrial Recovery Act of 1933 (NIRA), a main component of President Franklin D. Roosevelt's New Deal, unconstitutional. The case from which the ruling stemmed was nicknamed the "Sick Chicken Case".
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.
Florida Lime & Avocado Growers, Inc. v. Paul, 373 U.S. 132 (1963), was a 1963 decision of the United States Supreme Court in which the Court declined to invalidate a California law that imposed minimum fat content standards on avocados sold in the state, including those imported from other states. The law prohibited the sale of avocados that did not contain at least 8% oil by weight. Florida, a major avocado producer, employed, for wholesale marketing purposes, a federal standard unrelated to oil content. Most Florida avocados that were marketable at home failed to meet the California standard, because they were a different variety from those sold in California, with a lower fat content. Accordingly, Florida avocado growers brought this suit, arguing (unsuccessfully) that the California law (1) was preempted by federal law, (2) violated equal protection, and (3) unduly burdened and interfered with their right to engage in interstate commerce. The case is widely used in law school casebooks on constitutional law and federal jurisdiction as illustrative of preemption issues.
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.
Braunfeld v. Brown, 366 U.S. 599 (1961), was a landmark case on the issue of religious and economic liberty decided by the United States Supreme Court.

Dean Milk Co. v. City of Madison, Wisconsin, 340 U.S. 349 (1951), was a United States Supreme Court case dealing with the Dormant Commerce Clause, used to prohibit states from limiting interstate commerce.
Chemical Waste Management, Inc. v. Hunt, 504 U.S. 334 (1992), was a United States Supreme Court case that held that an Alabama law imposing a fee on out-of-state hazardous waste being disposed of in-state violated the Dormant Commerce Clause.
Hughes v. Alexandria Scrap Corp., 426 U.S. 794 (1976), was a case argued before the Supreme Court of the United States. Maryland created a program that, 1) purchased junked cars, 2) paid a bounty for those with Maryland license plates and, 3) imposed more stringent documentation requirements on out-of-state processors, in an effort to reduce the number of abandoned cars in Maryland.
Lingle v. Chevron U.S.A. Inc., 544 U.S. 528 (2005), was a landmark case in United States regulatory takings law whereby the Court expressly overruled precedent created in Agins v. City of Tiburon. Agins held that a government regulation of private property effects a taking if such regulation does not substantially advance legitimate state interests. Writing for the Court, Justice O’Connor found the test untenable for a number of reasons, but declined to grant Chevron relief because Chevron’s motion before the court was limited to a discussion of the “substantially advances” theory which had just been struck down. The Court remanded to the Ninth Circuit for a determination of whether the statute exacted a taking according to the formula of Penn Central.
United States v. Locke, 529 U.S. 89 (2000), was a United States Supreme Court case in which the Court unanimously held that certain state regulations regarding oil tankers and oil barges are preempted under the Supremacy Clause of the United States Constitution in deference to the extensive body of federal regulations affecting these classes of vessels.

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.
Brown v. Maryland, 25 U.S. 419 (1827), was a significant United States Supreme Court case which interpreted the Import-Export and Commerce Clauses of the U.S. Constitution to prohibit discriminatory taxation by states against imported items after importation, rather than only at the time of importation. The state of Maryland passed a law requiring importers of foreign goods to obtain a license for selling their products. Brown was charged under this law and appealed. It was the first case in which the U.S. Supreme Court construed the Import-Export Clause. Chief Justice John Marshall delivered the opinion of the court, ruling that Maryland's statute violated the Import-Export and Commerce Clauses and the federal law was supreme. He alleged that the power of a state to tax goods did not apply if they remained in their "original package". A license tax on the importer was essentially the same as a tax on an import itself. Despite arguing the case for Maryland, future chief justice Roger Taney admitted that the case was correctly decided.
National Pork Producers Council v. Ross, 598 U.S. ___ (2023), was a United States Supreme Court case related to the Dormant Commerce Clause.
