THE CHILD LABOR LAW CASE 45 THE CHILD LABOR LAW CASE ON June 3, 19 18, the Supreme Court of the United States held unconstitutional the act of Congress of September i, 1916, entitled "An Act to prevent interstate commerce in the products of child labor and for other purposes." ^ Mr. Justice Day delivered the opinion of the majority of the court.^ With the dissenting opinion, written by Mr. Justice Holmes, Mr. Justice McKenna, Mr. Justice Brandeis, and Mr. Justice Clarke concurred. The first section of the act is in the footnote.^ The court held that the act was not a regulation of interstate commerce, but rather of the hours of labor in manufacturing, — a matter exclusively reserved for state control. It was not held that the act was a regulation of interstate commerce and also of manu- facturing; and that the two provisions were inseparable, hence the act was invalid.'* Nor was any point made in either opinion that the act was not confined to the products of child labor, but being directed against the products of the factory in which the child works, was therefore confiscatory and contrary to the Fifth Amendment.^ 1 C. 432, 39 Stat. 675.
