Commerce Clause
The Commerce Clause, found in Article I, Section 8 of the U.S. Constitution, grants Congress the authority to regulate trade among the states, with foreign nations, and with Indian tribes. This provision has played a critical role in shaping the United States’ economic system by facilitating a cohesive regulatory framework for interstate commerce. The pivotal Supreme Court case Gibbons v. Ogden in 1824 established that the Commerce Clause applies primarily to interstate commerce and defined commerce broadly to include various types of economic interaction. Over the years, the clause has served as the foundation for significant federal legislation, including the establishment of the Interstate Commerce Commission and the Sherman Antitrust Act, aimed at regulating transportation and preventing monopolistic practices.
In the 20th century, the scope of the Commerce Clause expanded to address issues such as public safety and civil rights, with landmark cases affirming Congress's power to legislate against discrimination by linking it to the impact on interstate commerce. Recent cases continue to test the boundaries of the Commerce Clause, including challenges to state laws that affect interstate trade, exemplified by the National Pork Producers Council v. Ross decision in 2023. Overall, the Commerce Clause remains a vital and dynamic element of U.S. law, influencing various aspects of economic policy and regulation while reflecting the evolving nature of commerce and societal values.

Commerce Clause
Description: The clause in the United States (US) Constitution giving Congress the power to regulate trade among the states
Relevant amendment: Tenth
Significance: The Supreme Court has upheld congressional use of the Commerce Clause as justification for a broad range of federal legislation
Article I, section 8 of the U.S. Constitution states that Congress “shall have the power . . . to regulate commerce with foreign nations, and among the several states, and with the Indian tribes.” The part of this clause dealing with the states was extremely important in enabling the US to develop an effective, integrated economic system. Still, its influence reaches far beyond the realm of a narrow definition of commerce. The first Supreme Court case involving the Commerce Clause, Gibbons v. Ogden (1824), established that it applies to interstate commerce but not to commerce within one state. Chief Justice John Marshall’s opinion in the case broadly defined commerce as all commercial “intercourse,” not only the traffic of goods. In the late nineteenth century, the Commerce Clause was cited as justification for the congressional establishment of the Interstate Commerce Commission (ICC) and the Sherman Antitrust Act (1890). The ICC was set up in 1887 to regulate railroads, trucking, and telecommunications, while the Sherman Antitrust Act gave the federal government power to prohibit anticompetitive behavior and break up monopolies. All of these areas of regulation applied in some form to commerce between the states.

In the early twentieth century, the federal government began using the Commerce Clause as the basis for national legislation involving crime, public safety, and morality, as in the Mann Act (1910), which prohibited human trafficking (especially in the form of prostitution) between the states, and the Automobile Theft Act of 1915, which made it a federal crime to drive a stolen car across state lines. Until the 1930s, the Supreme Court maintained a distinction between manufacturing and commerce, but in 1937 it began to interpret the Commerce Clause broadly enough to allow regulating the manufacture of goods intended for interstate transportation and sale. Since World War II, considerable federal legislation has been based on the Commerce Clause. One of its most remarkable uses was justifying civil rights legislation in the 1960s. In cases such as Heart of Atlanta Motel v. United States (1964), the Supreme Court held that, because racial discrimination hurts interstate commerce, Congress can pass and enforce antidiscrimination laws.
In the twenty-first century, cases involving the Commerce Clause have continued to focus on its interpretation and application. In National Pork Producers Council v. Ross (2023), the National Pork Producers Council argued that California’s Proposition 12, a law restricting the sale of pork in California unless it met specific animal welfare standards, violated the Commerce Clause because it reached out of state and placed burdens on interstate commerce. The Supreme Court upheld the law, arguing against the National Pork Producers Council, stating Proposition 12 did not purposefully discriminate against out-of-state economic interests.
