Mr. Justice Roberts
delivered the opinion of the Court.
This is a suit to restrain the petitioners from picketing the respondent's place of business; from coercing the respondent to discharge any of its employes who do not belong to the petitioning union, or to compel them to become members of the union and to accept it as their bargaining agent and representative; and from advertising that the respondent is unfair to organized labor, or molesting customers or prospective customers or persuading them to cease patronizing it. After a hearing, and upon findings of fact and conclusions of law, the District Court granted a preliminary injunction. The Circuit Court of Appeals affirmed. Upon final hearing the parties relied upon the record as made in the preliminary hearing and some additional testimony.
The District Court found the following facts: The respondent is a Delaware corporation maintaining five meat markets in Milwaukee, Wisconsin. The petitioners are, respectively, an unincorporated labor union and its business manager, citizens and residents of Wisconsin. • The respondent's employes number about thirty-five; none of them are members of the petitioning union. The petitioners made demand upon the respondent to require its employes, as a condition of their continued employment, to become members of the union. The respondent notified the employes that they were free to do this and that it was willing to permit them to join but they declined and refused to join. The union had not been chosen by the employes to represent them in any matter connected with the respondent. For the purpose of coercing the respondent to require its employes to join the union and to accept it as their bargaining agent and representative, as a condition of continued employment, and for the purpose of injuring and destroying the business if the respondent refused to yield to such coercion, the petitioners conspired to do the following things and did them: They caused false and misleading signs to be placed before the respondent's markets; caused persons who were not respondent's employes to parade and picket before the markets; falsely accused respondent of being unfair to organized labor in its dealings with employes, and, by molestation, annoyance, threats, and intimidation prevented patrons and prospective patrons of respondent from patronizing its markets; respondent suffered and will suffer irreparable injury from the continuance of the practice and customers will be intimidated and restrained from patronizing the stores as a consequence of petitioners' acts. There is more than $3,000 involved in the controversy.
The District Court held that no labor dispute, as defined by federal or state law, exists between the respondent and the petitioners or either of them; that the respondent is bound to permit its employes free agency in the matter of choice of union organization or representation; and that the respondent had no adequate remedy at law. It entered a final decree enjoining the petitioners from seeking to coerce the respondent to discharge any of its employes for refusal to join the union or to coerce the respondent to compel employes to become members of the organization, from advertising that the respondent is unfair to organized labor, and from annoying or molesting patrons or persuading or soliciting customers, present or prospective, not to patronize the respondent's markets.
The Circuit Court of Appeals affirmed the decree. By reason of alleged conflict with a decision of the Supreme Court of Wisconsin. [222 Wis. 383; 268 N. W. 270, 873] and with our decision in Senn v. Tile Layers Protective Union, 301 U. S. 468, we granted the writ of certiorari.
In the Court of Appeals the petitioners assigned error to certain of the District Court's findings of fact as well as to its conclusions of law. In this court the only errors assigned are to the holdings that, on the facts found, there was no labor dispute and that the Norris-LaGuardia Act and the Wisconsin Labor Code had no bearing on the case as made. In these circumstances we accept the findings of fact and confine our inquiry to the correctness of the District Court's conclusions based upon them.
The institution of the suit in the federal court is justified by the findings as to diversity of citizenship and the amount in controversy. As the acts complained of occurred in Wisconsin the law of that State governs the substantive rights of the parties. But the power of the court to grant the relief prayed depends upon the jurisdiction conferred upon it by the statutes of the United States.
First. The District Court erred in holding that no labor dispute, as defined by the law of Wisconsin, existed between the parties. Section 103.62, paragraph (3) of the Wisconsin Labor Code, is:
"The term 'labor dispute' includes any controversy concerning the terms or conditions of employment, or concerning the association or representation of persons in negotiating, fixing, maintaining, changing, or seeking to arrange terms or conditions of employment, or concerning employment relations, or any other controversy arising out of the respective interests of employer and employe, regardless of whether or not the disputants stand in the proximate relation of employer and employe."
The District Court was bound by the construction of the section by the Supreme Court of the State, which has held a controversy indistinguishable from that here disclosed to be a labor dispute within the meaning of the statute.
Second. The District Court erred in not applying the provisions of § 103.53 of the Wisconsin Labor Code, which declares certain conduct lawful in labor disputes; inter alia "giving publicity to . . . the existence of, or the facts involved in, any dispute . . . by . . . patrolling any public street . . . without intimidation or coercion, or by any other method not involving fraud, violence, breach of the peace, or threat thereof"; advising, urging, or inducing, without fraud, violence or threat thereof, others to cease to patronize any person; peaceful picketing or patrolling, whether singly or in numbers. A Wisconsin court could not enjoin acts declared by the statute to be lawful; and the District Court has no greater power to do so. The error into which the court fell as to the existence of a labor dispute led it into the further error of issuing an order so sweeping as to enjoin acts made lawful by the State statute. The decree forbade all picketing, all advertising that the respondent was unfair to organized labor and all persuasion and solicitation of customers or prospective customers not to trade with respondent.
Third. The District Court erred in granting an injunction in the absence of findings which the Norris-LaGuardia Act makes prerequisites to the exercise of jurisdiction.
Section 13 (c) of the Act is:
"The term 'labor dispute' includes any controversy Concerning terms or conditions of employment, or concerning the association or representation of persons in negotiating, fixing, maintaining, changing, or seeking to arrange terms or conditions of employment regardless of whether or not the disputants stand in the proximate relation of employer and employee."
This definition does not differ materially from that above quoted from the Wisconsin Labor Code, and the facts of the instant case bring it within both.
Section 7 declares that "no court of the United States shall have jurisdiction to issue a temporary or permanent injunction in any case involving or growing out of a labor dispute, as herein defined" except after a hearing of a described character, "and except after findings of fact by the court, to the effect (a) that unlawful acts have been threatened and will be committed unless restrained or have been committed and will be continued unless restrained" and that no injunction "shall be issued on account of any threat or unlawful act excepting against the person or persons, association, or organization making the threat or committing the unlawful act or actually authorizing or ratifying the same . . ." By subsections (b) to (e) it is provided that relief shall not be granted unless the court finds that substantial and irreparable injury to complainants' property will follow; that as to each item of relief granted greater injury will be inflicted upon the complainant by denying the relief than will be inflicted upon defendants by granting it; that complainant has no adequate remedy at law; and that the public officers charged with the duty to protect complainants' property are unable or unwilling to provide adequate protection. There can be no question of the power of Congress thus to define and limit the jurisdiction of the inferior courts of the United States. The District Court made none of the required findings save as to irreparable injury and lack of remedy at law. It follows that in issuing the injunction it exceeded its jurisdiction.
Fourth. The Court of Appeals erred in holding that the declarations of policy in the Norris-LaGuardia Act and the Wisconsin Labor Code to the effect that employes are to have full freedom of association, self-organization, and designation of representatives of their own choosing, free from interference, restraint or coercion of their employers, puts this case outside the scope of both acts since respondent cannot accede to the petitioner's demands upon it without disregarding the policy declared by the statutes. This view was expressed in the court's first opinion on the appeal from the issue of an interlocutory injunction, and the opinion on the appeal from the final order adopts what was said on the earlier appeal as the law of the case. We find nothing in the declarations of policy which narrows the definition of a labor dispute as found in the statutes. The rights of the parties and the jurisdiction of the federal courts are to be determined according to the express provisions applicable to labor disputes as so defined.
Fifth. Since the courts below were of opinion that a labor dispute, as defined by state and federal statutes, had not been shown, they did not pass on the questions of the legality, under the Wisconsin law, of the acts charged to have been done by the petitioners or the constitutionality of that law in legalizing any of such acts. As the case must go back for further proceedings, we express no opinion upon these questions.
The judgment is reversed and the cause remanded to the District Court for further proceedings in conformity with this opinion.
Reversed.
