In upholding a federal statute that prohibited the transportation of lottery tickets in interstate commerce, the Supreme Court defined commerce broadly and authorized the development of a federal police power.

Although the U.S. Constitution contains no federal police power, a broad interpretation of the commerce clause allowed the federal government to become involved with the public’s safety, health, morality, and welfare. In the late nineteenth century, Congress began to enact commerce-based police power legislation. For example, the Federal Lottery Act of 1895 had the goal of attacking gambling activities rather than regulating an object of commerce. When C. F. Champion was convicted of disobeying the statute, he asserted that the act was unconstitutional for three reasons: First, lottery tickets, as such, were not objects of commerce; second, even if they were objects of commerce, the word “regulate” in the commerce clause did not include the power to prohibit; and third, only the states, according to the Tenth Amendment, could exercise the police power.Interstate commerce;Champion v.

Speaking for a 5-4 majority, Justice John Marshall HarlanHarlan, John Marshall;Champion v. Ames[Champion v. Ames] emphasized the plenary nature of congressional power over interstate commerce. Lottery tickets were objects of real value and therefore items of commerce. The power to regulate commerce, moreover, encompassed the power to prohibit any products considered intrinsically harmful to the public. The effect of the so-called Lottery Case[case]Lottery Case[Lottery Case] was to recognize that Congress might exercise a de facto police power, as desired by ProgressivesProgressivism of the era. Based on the precedent, the Court upheld the Pure Food and Drug Act of 1906 in Hipolite Egg Co. v. United States[case]Hipolite Egg Co. v. United States[Hipolite Egg Co. v. United States] (1911), and it upheld the Mann Act of 1910 (involving white slavery) in Hoke v. United States[case]Hoke v. United States[Hoke v. United States] (1913). During this era, the Court’s acceptance of a federal police power was limited to regulation of criminal or “sinful” activities and did not extend to most economic regulations.
