The Court, led by Mr. Justice Stone, examined the constitutionality of the "Filled Milk Act" of 1923, which bans the interstate shipment of skimmed milk mixed with non-milk fats or oils that mimic milk or cream. The appellee was indicted for shipping "Milnut," a product made from condensed skimmed milk and coconut oil, deemed adulterated and harmful to public health. The trial court had dismissed the indictment, citing a prior case, while the Seventh Circuit Court of Appeals had upheld the Act's validity as an exercise of Congress's commerce power. 

The appellee challenged the Act on grounds that it exceeded Congress's powers under the interstate commerce clause and infringed on states' rights as reserved by the Tenth Amendment. Additionally, the appellee argued that the statute violated the Fifth Amendment by denying equal protection and due process, particularly by asserting that the product was conclusively deemed harmful. The Court clarified that Congress possesses the authority to regulate commerce comprehensively, including prohibiting shipments it perceives as detrimental to public health, morals, or welfare. This regulatory power does not infringe on state authority unless it violates due process, and the exercise of such power may coincide with state police powers without being deemed unconstitutional.

The regulation prohibiting the shipment of filled milk in interstate commerce is deemed permissible, with its constitutionality anchored in the Fifth Amendment. The prohibition does not violate the Fifth Amendment, as established in Hebe Co. v. Shaw, which upheld a state law against the manufacturing and sale of a product made from condensed skimmed milk and coconut oil, asserting that legislative power includes ensuring food safety and protecting public health from fraudulent substitutes. The Filled Milk Act, enacted after extensive hearings with expert testimonies, supports the conclusion that filled milk substitutes are generally detrimental to health and facilitate fraud. Congressional committees confirmed that inferior products, which closely resemble pure milk, pose increased risks to consumers. The statute's effectiveness hinges on distinguishing products that mimic milk, and the necessity of legislative action over judicial intervention is emphasized. The argument that the statute unfairly targets filled milk while not extending similar prohibitions to oleomargarine or other substitutes is countered by noting that the Fifth Amendment lacks an equal protection clause, and legislative discretion is upheld in addressing public health issues.

A legislature can address an identified abuse even if it does not target all related issues. Legislative declarations characterizing certain products, like filled milk, as harmful or fraudulent serve to support the constitutional exercise of legislative power and assist judicial review. Such characterizations do not preclude challenges to the legitimacy of the legislation based on the absence of a rational basis. Courts may presume the existence of facts supporting legislative judgment, and statutes can be challenged if it can be shown that the underlying factual basis has changed or does not apply to specific cases. Inquiries into the validity of legislation must focus on whether any known or reasonably assumed facts support the legislative judgment. The determination of whether to regulate or prohibit certain commerce, like filled milk, is within the purview of Congress, and judicial findings or jury verdicts cannot replace legislative decisions.

The prohibition of shipping appellee’s product in interstate commerce is upheld as a constitutional regulation of interstate commerce. The demurrer should have been overruled, leading to the reversal of the judgment. Justice Black concurs with the overall opinion, excluding a subsection, while Justice McReynolds advocates for affirming the judgment. Justices Cardozo and Reed did not participate in the case.

The statute defines “filled milk” as any milk product, including cream and skimmed milk, that has been blended with non-milk fats or oils, creating a product that resembles milk. It declares filled milk as adulterated and harmful to public health, making its shipment unlawful. Violations can result in fines up to $1,000 or imprisonment for up to one year.

There is a significant market for milk compounds made from condensed milk with removed butter fat, replaced by vegetable oils, which are cheaper and mimic the taste and appearance of pure milk. This substitution can lead to undernourishment, particularly in children, due to the lack of essential nutrients found in butter fat. 

Despite compliance with labeling laws, filled milk is often sold as a substitute for pure milk, contributing to public confusion due to similarities in taste, packaging, and marketing practices. The consumption of filled milk is prevalent in hotels, boarding houses, and food manufacturers, where labeling restrictions are less effective. Scientific literature emphasizes the critical role of butter fat and whole milk in providing essential vitamins for health. By the time of the Filled Milk Act's passage, eleven states had already restricted or banned filled milk, and currently, approximately thirty-five states have similar prohibitions.

The document cites a comprehensive list of state statutes from various jurisdictions, primarily focusing on agricultural and regulatory codes from the early to mid-20th century. It notes that some states have imposed strict regulations on the sale of certain products, referencing specific laws from Colorado, Oregon, and Washington. The excerpt discusses the principle of the presumption of constitutionality of legislation, noting that this presumption may be limited when laws appear to violate explicit constitutional prohibitions, specifically those found in the first ten amendments, which are applicable under the Fourteenth Amendment. Various landmark Supreme Court cases are mentioned to illustrate the potential for heightened judicial scrutiny of laws that restrict political processes, voting rights, the dissemination of information, political organization, and peaceful assembly. The text also raises the question of whether certain laws targeting specific religious or racial groups warrant more rigorous judicial review, suggesting that prejudice against discrete and insular minorities may necessitate a more thorough examination of legislative intent and impact.
