Through Justice Holmes, the court held that the discount clause, designed to aid in upbuilding the American merchant marine, is inoperative altogether, because of conflict with existing treaties, it was held inapplicable both to American vessels and to those of twenty-two foreign nations having treaties prohibiting discrimination. The Supreme Court refused to reconsider its recent ruling in the so-called "Diggs-Caminetti white slave" cases, in which it held that the Mann white slave law applies to private, personal escapades as well as commercialized vice. The court denied the application of Drew Caminetti for the hearing.
