Inasmuch as equitable relief has in so many cases been obtained by employers organized labour has denounced the use of the in junction. And certain abuses have appeared in the granting of injunction relief. Frequently the courts have hastily and errone ously enjoined conduct which on subsequent examination was found not to threaten irreparable injury to complainant's property. Orders have been expressed in ambiguous language. Moreover the findings have not always justified the sweeping and inclusive character of the restraints. Orders have often been issued on the basis of ex parte affidavits without giving notice and opportunity to be heard. To correct some of these abuses Congress enacted the Clayton Act in 1914. But in a series of cases the courts in terpreted the Act to be merely declaratory of previous law. Thus, few significant changes in practice occurred.
Finally in 1932 the Norris-LaGuardia Act received Congres sional approval. The Act withdraws equity jurisdiction from the Federal courts in cases involving labour disputes under stated circumstances. Injunctions may not issue to prevent persons from obtaining work, paying strike benefits, giving publicity to the facts of a labour dispute by any method not involving fraud or violence or advising others to do the acts specified. Both equi
table and legal protection is withheld from the "yellow dog con tract." Exemptions from legal restraint are no longer confined to disputes between persons standing in the direct relationship of employer and employees. Procedural safeguards are established. In those courts where injunctions may issue, the Act requires Equity courts to make findings that unlawful acts are threatened, that irreparable injury will result to complainants' property un less relief is granted, that complainant has no adequate remedy at law and as to each item of relief granted greater injury will be inflicted upon complainant by the denial of relief than will be inflicted upon defendant by the granting of relief. Moreover it must be shown that the local police force is unwilling or unable to furnish adequate protection. The passage of the Norris-La Guardia Act has diminished the number of injunctions issued by Federal courts. To mitigate similar abuses in the exercise of equi table jurisdiction in state courts, several states have passed simi lar statutes.
For the purpose of encouraging the making of trade agree ments, which is the aim of all collective bargaining, both the Fed eral Government and the states have legislatively provided for voluntary arbitration or conciliation or mediation. Within the United States Department of Labor, a conciliation service which is authorized to mediate whenever in the judgment of the Secre tary of Labor "the interest of industrial peace may so require" has existed since the inception of the Department ; and it is re ported by the Conciliation Service that from 193o to 1934 dis putes and differences which either directly or indirectly affected approximately 2,230,000 workers were amicably adjusted through its good offices, either on its own volition or with the cooperation of the State Departments of Labor and local agencies. In one state, compulsory investigation of labour disputes, accompanied by a prohibition of strikes pending the completion of investiga tion, exists. But, most state laws provide for government interven tion on a basis of conciliation and voluntary arbitration.
