St. John v. New York
Argued March 14, 1906
Decided April 16, 1906
201 U.S. 633
A state may classify persons and objects for the purpose of legislation, provided the classification is based on proper and justifiable distinctions, and so held that c. 338 of the laws of New York of 1893, prohibiting the sale of adulterated milk, is not in conflict with the equal protection clause of the Fourteenth Amendment because in certain respects it provides different prohibitions and penalties as to producing and nonproducing vendors of milk.
The facts are stated in the opinion.
