Jacobs with his wife and two children lived in a tenement house in the city of New York and occupied an apartment of seven rooms in a building where there were only three other apartments, all of equal size. In this apartment he carried on the trade of manufacturing cigars, and the rooms in which he did so were separated from the sleeping and cooking-rooms. The testimony showed that there was no odor of tobacco in these sleeping and cooking-rooms. The conditions under which he was carrying on his trade in his own home for the support of himself and his family were much more healthful than if he and his assistants had been compelled to work in a crowded factory, particularly in 1884, when there were no such sanitary conditions in factories as now prevail under the beneficent operation of our present public health and labor laws. It was shown that, when this legislation was enacted, 840,000,000 cigars were being manufactured annually in the city of New York, of which about 370,000,000, or 44 per cent., were made in the homes of dwellers in tenement or apartment houses, and that about two thousand artisans were supporting themselves and their families by thus working at home. The board of health of the city of New York had officially declared, after careful investigation, as set forth in the brief of Mr. Evarts, then the leader of the American bar, "that the health of the tenement-house population is not jeopardized by the manufacture of cigars in those houses; that this bill is not a sanitary measure, and that it has not been approved by this board." It also appeared from this brief that while the death-rate in the city of New York generally was 31 in each 1,000, it was only 9 in each 1,000 in the tenement houses where cigars were being manufactured. The act, if valid and enforceable, would have crushed the competition of home workers with the tobacco factories; it would have deprived the tenement-house dweller of the liberty to exercise his trade of cigar-making at home even under the most sanitary conditions, and it would have driven every such workman and the working members of his family into crowded and generally unhealthful factories, to be harassed and oppressed by strikes and lockouts and the other troubles which attend modern labor conditions, to say nothing of being exposed to all the mischiefs, physical and moral, that are inseparable from crowded workshops. The court held that the statute was not a legitimate health regulation and released Jacobs from imprisonment. The principle of constitutional law recognized and applied was that an individual cannot be made a criminal for working at a lawful trade in his own home under sanitary conditions, and cannot be compelled by discriminatory legislation to labor in a crowded factory. If the provisions of the act had not been declared to be in conflict with the constitutional guaranty of personal liberty, similar statutes could have been passed with respect to all
