In 1829 New York State had made "conspiracy to commit any act injurious to public morals or to trade or commerce" a statutory offence, thus reenforcing the existing common law. In 1835 the shoemakers of Geneva struck to enforce the closed shop against a workman who persisted in working below the union rate. The indictment went no further than charging this offence. The journeymen were convicted in a lower court and appealed to the Supreme Court of the State. Chief Justice Savage, in his decision condemning the journeymen, broadened the charge to include a conspiracy to raise wages and condemned both as "injurious to trade or commerce" and thus expressly covered by statute.

The far-reaching effects of this decision came clearly to light in a tailor's case the next year. The journeymen were charged with practising intimidation and violence, while picketing their employers' shops during a prolonged strike against a reduction in wages. Judge Edwards, the trial judge, in his charge to the jury, stigmatized the tailors' society as an illegal combination, largely basing himself upon Judge Savage's decision. The jury handed in a verdict of guilty, but recommended mercy. The judge fined the president of the society $150, one journeyman $100, and the others $50 each. The fines were immediately paid with the aid of a collection taken up in court.

The decisions produced a violent reaction among the workingmen. They held a mass-meeting in City Hall Park, with an estimated attendance of 27,000, burned Judge Savage and Judge Edwards in effigy, and resolved to call a state convention to form a workingmen's party.

So loud, indeed, was the cry that justice had been thwarted that juries were doubtless influenced by it. Two cases came up soon after the tailors' case, the Hudson, New York, shoemakers' in June and the Philadelphia plasterers' in July 1836. In both the juries found a verdict of not guilty. Of all journeymen indicted during this period the Hudson shoemakers had been the most audacious ones in enforcing the closed shop. They not only refused to work for employers who hired non-society men, but fined them as well; yet they were acquitted.

Finally six years later, in 1842, long after the offending trade societies had gone out of existence under the stress of unemployment and depression, came the famous decision in the Massachusetts case of Commonwealth v. Hunt.

This was a shoemakers' case and arose out of a strike. The decision in the lower court was adverse to the defendants. However, it was reversed by the Supreme Judicial Court of Massachusetts. The decision, written by Chief Justice Shaw, is notable in that it holds trade unions to be legal organizations. In the earlier cases it was never in so many words held that trade unions were unlawful, but in all of them there were suggestions to this effect. Now it was recognized that trade unions are per se lawful organizations and, though men may band themselves together to effect a criminal object under the disguise of a trade union, such a purpose is not to be assumed without positive evidence. On the contrary, the court said that "when an association is formed for purposes actually innocent, and afterwards its powers are abused by those who have the control and management of it to purposes of oppression and injustice, it will be criminal in those who misuse it, or give consent thereto, but not in other members of the association." This doctrine that workingmen may lawfully organize trade unions has since Commonwealth v. Hunt been adopted in nearly every case.

The other doctrine which Justice Shaw advanced in this case has been less generally accepted. It was that the members of a union may procure the discharge of non-members through strikes for this purpose against their employers. This is the essence of the question of the closed shop; and Commonwealth v. Hunt goes the full length of regarding strikes for the closed shop as legal. Justice Shaw said that there is nothing unlawful about such strikes, if they are conducted in a peaceable manner. This was much in advance of the position which is taken by many courts upon this question even at the present day.

After Commonwealth v. Hunt came a forty years' lull in the courts' application of the doctrine of conspiracy to trade unions. In fact so secure did trade unionists feel from court attacks that in the seventies and early eighties their leaders advocated the legal incorporation of trade unions. The desire expressed for incorporation is of extreme interest compared with the opposite attitude of the present day. The motive behind it then was more than the usual one of securing protection for trade union funds against embezzlement by officers. A full enumeration of other motives can be obtained from the testimony of the labor leaders before the Senate Committee on Education and Labor in 1883. McGuire, the national secretary of the Brotherhood of Carpenters and Joiners, argued before the committee for a national incorporation law mainly for the reason that such a law passed by Congress would remove trade unions from the operation of the conspiracy laws that still existed though in a dormant state on the statute books of a number of Slates, notably New York and Pennsylvania. He pleaded that "if it (Congress) had not the power, it shall assume the power; and, if necessary, amend the constitution to do it." Adolph Strasser of the cigar makers raised the point of protection for union funds and gave as a second reason that it "will give our organization more stability, and in that manner we shall be able to avoid strikes by perhaps settling with our employers, when otherwise we should be unable to do so, because when our employers know that we are to be legally recognized that will exercise such moral force upon them that they cannot avoid recognizing us themselves." W.H. Foster, the secretary of the Legislative Committee of the Federation of Organized Trades and Labor Unions, stated that in Ohio the law provided for incorporation at a slight cost, but he wanted a national law to "legalize arbitration," by which he meant that "when a question of dispute arose between the employers and the employed, instead of having it as now, when the one often refuses to even acknowledge or discuss the question with the other, if they were required to submit the question to arbitration, or to meet on the same level before an impartial tribunal, there is no doubt but what the result would be more in our favor than it is now, when very often public opinion cannot hear our cause." He, however, did not desire to have compulsory arbitration, but merely compulsory dealing with the union, or compulsory investigation by an impartial body, both parties to remain free to accept the award, provided, however, "that once they do agree the agreement shall remain in force for a fixed period." Like Foster, John Jarrett, the President of the Amalgamated Association of Iron and Steel Workers, argued for an incorporation law before the committee solely for its effect upon conciliation and arbitration. He, too, was opposed to compulsory arbitration, but he showed that he had thought out the point less clearly than Foster.

The young and struggling trade unions of the early eighties saw only the good side of incorporation without its pitfalls; their subsequent experience with courts converted them from exponents into ardent opponents of incorporation and of what Foster termed "legalized arbitration."

During the eighties there was much legislation applicable to labor disputes. The first laws against boycotting and blacklisting and the first laws which prohibited discrimination against members who belonged to a union were passed during this decade. At this time also were passed the first laws to promote voluntary arbitration and most of the laws which allowed unions to incorporate. Only in New York and Maryland were the conspiracy laws repealed. Four States enacted such laws and many States passed laws against intimidation. Statutes, however, played at that time, as they do now, but a secondary role. The only statute which proved of much importance was the Sherman Anti-Trust Act. When Congress passed this act in 1890, few people thought it had application to labor unions. In 1893-1894, as we shall see, however, this act was successfully invoked in several labor controversies, notably in the Debs case.
