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.
Wickard v. Filburn, 317 U.S. 111 (1942), is a United States Supreme Court decision that dramatically increased the regulatory power of the federal government. It remains as one of the most important and far-reaching cases concerning the New Deal, and it set a precedent for an expansive reading of the U.S. Constitution's Commerce Clause for decades to come. The goal of the legal challenge was to end the entire federal crop support program by declaring it unconstitutional.

The act revived the provisions in the previous Agriculture Adjustment Act, with the exception that the financing of the law's programs would be provided by the Federal Government and not a processor's tax, and was also enforced as a response to the success of the Soil Conservation and Domestic Allotment Act of 1936.
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.

The Aggregate effects doctrine, Cumulative effects doctrine, or substantial effects is a legal doctrine in United States federal law. The AED permits extension of the regulation of interstate commerce into any action which affects interstate commerce only when aggregated with other actions. It is most often associated with Wickard v. Filburn 1942. In Wickard a wheat farmer growing wheat solely for animal feed within the confines of his own farm was found to be regulatable because private growth for private consumption was the primary reason for decrease of demand.
