Local 1976, United Brotherhood of Carpenters and Joiners of America, A.F.L. v. National Labor Relations Board/Opinion of the Court

These cases involve so-called 'hot cargo' provisions in collective bargaining agreements. More particularly, they raise the question whether such a provision is a defense to a charge against a union of an unfair labor practice under § 8(b)(4)(A) of the National Labor Relations Act, as amended, 61 Stat. 136, 141, 29 U.S.C. § 158(b)(4)(A), 29 U.S.C.A. § 158(b)(4)(A).

No. 127 arises out of a labor dispute between carpenter unions and an employer engaged in the building construction trade in Southern California. The Sand Door and Plywood Company is the exclusive distributor in Southern California of doors manufactured by the Paine Lumber Company of Oshkosh, Wisconsin. Watson and Dreps are millwork contractors who purchase doors from Sand. Havstad and Jensen are general contractors who were, at the time of the dispute involved, engaged in the construction of a hospital in Los Ageles. Havstad and Jensen are parties to a master labor agreement negotiated with the United Brotherhood of Carpenters and Joiners of America on behalf of its affiliated district councils and locals, including petitioner unions. This agreement, comprehensively regulating the labor relations of Havstad and Jensen and its carpenter employees, includes a provision that, 'workmen shall not be required to handle non-union material.'

In August 1954 doors manufactured by Paine and purchased by Sand were delivered to the hospital construction site by Watson and Dreps. On the morning of August 17, Fleisher, business agent of petitioner Local 1976, came to the construction site and notified Steinert, Havstad and Jensen's foreman, that the doors were nonunion and could not be hung. Steinert therefore ordered employees to cease handling the doors. When Nicholson, Havstad and Jensen's general superintendent, appeared on the job and asked Fleisher why the workers had been prevented from handling the doors, he stated that they had been stopped until it could be determined whether the doors were union or nonunion. Subsequent negotiations between officers of Sand and the union failed to produce an agreement that would permit the doors to be installed.

On the basis of charges filed by Sand and a complaint duly issued, the National Labor Relations Board found that petitioners had induced and encouraged employees to engage in a strike or concerted refusal to handle Paine's doors in order to force Havstad and Jensen and Sand to cease doing business with Paine, all in violation of § 8(b)(4)(A). 113 N.L.R.B. 1210. The Court of Appeals for the Ninth Circuit enforced the Board's cease-and-desist order, 241 F.2d 147, and we granted certiorari, 355 U.S. 808, 78 S.Ct. 13, 2 L.Ed.2d 27. The sole question tendered by the petition for certiorari concerned the relation between the hot cargo provision in the collective bargaining agreement and the charge of an unfair labor practice proscribed by § 8(b)(4)(A).

Nos. 273 and 324 arise out of a labor dispute in Oklahoma City in which certain unions are said to have induced the employees of five common carriers to cease handling the goods of another employer in violation of § 8(b)(4)(A). American Iron and Machine Works was engaged in a controversy with Local 850 of the International Association of Machinists, the bargaining representative of its production and maintenance employees, and a strike had been called at the company's plants. Picketing at the plants prevented the carriers that normally served American Iron from making pickup and deliveries, so American Iron hauled freight in its own trucks to the loading platforms of the carriers. The Machinists followed the trucks to the carriers' platforms and picketed them there, without making it clear that their dispute was only with American Iron. In addition, there was evidence that they expressly requested employees of some of the carriers not to handle American Iron freight. Teamsters Union Local 886, representative of the carriers' employees, instructed the employees to cease handling the freight. All the carriers except one expressly ordered their employees to move American Iron freight, but nevertheless they refused to do so. The Teamsters' contract with the carriers contained a provision that, 'Members of the Union shall not be allowed to handle or haul freight to or from an unfair company, provided, this is not a violation of the Labor Management Relations Act of 1947.'

On the basis of charges filed by American Iron, the Board issued complaints against the unions and found that both the Machinists and Teamsters, by their appeals or instructions to the carriers' employees, had violated § 8(b)(4)(A), notwithstanding the hot cargo provision in the collective bargaining agreement. 115 N.L.R.B. 800. The Court of Appeals for the District of Columbia Circuit set aside the order as to the Teamsters because of the hot cargo provision (No. 273), but enforced the order against the Machinists (No. 324). 101 U.S.App.D.C. 80, 247 F.2d 71. We granted certiorari in all three cases because of conflicts among the circuits as to the meaning of § 8(b)(4)(A), and because of the importance of the problem in the administration of the National Labor Relations Act, and ordered them consolidated for argument. 355 U.S. 808, 78 S.Ct. 42, 56, 2 L.Ed. 27.

Section 8(b)(4)(A) provides that, 'It shall be an unfair labor practice for a labor organization or its agents * *  * (4) to engage in, or to induce or encourage the employees of any employer to engage in, a strike or a concerted refusal in the course of their employment to use, manufacture, process, transport, or otherwise handle or work on any goods, articles, materials, or commodities or to perform any services, where an object thereof is: (A) forcing or requiring *  *  * any employer or other person to cease using, selling, handling, transporting, or otherwise dealing in the products of any other producer, processor, or manufacturer, or to cease doing business with any other person *  *  * .'

Whatever may have been said in Congress preceding the passage of the Taft-Hartley Act concerning the evil of all forms of 'secondary boycotts' and the desirability of outlawing them, it is clear that no such sweeping prohibition was in fact enacted in § 8(b)(4)(A). The section does not speak generally of secondary boycotts. It describes and condemns specific union conduct directed to specific objectives. It forbids a union to induce employees to strike against or to refuse to handle goods for their employer when an object is to force him or another person to cease doing business with some third party. Employees must be induced; they must be induced to engage in a strike or concerted refusal; an object must be to force or require their employer or another person to cease doing business with a third person. Thus, much that might argumentatively be found to fall within the broad and somewhat vague concept of secondary boycott is not in terms prohibited. A boycott voluntarily engaged in by a secondary employer for his own business reasons, perhaps because the unionization of other employers will protect his competitive position or because he identifies his own interests with those of his employees and their union, is not covered by the statute. Likewise, a union is free to approach an employer to persuade him to engage in a boycott, so long as it refrains from the specifically prohibited means of coercion through inducement of employees.

From these considerations of what is not prohibited by the statute, the true scope and limits of the legislative purpose emerge. The primary employer, with whom the union is principally at odds, has no absolute assurance that he will be free from the consequences of a secondary boycott. Nor have other employers or persons who deal with either the primary employer or the secondary employer and who may be injuriously affected by the restrictions on commerce that flow from secondary boycotts. Nor has the general public. We do not read the words 'other person' in the phrase 'forcing or requiring * *  * any employer or other person' to extend protection from the effects of a secondary boycott to such other person when the secondary employer himself, the employer of the employees involved, consents to the boycott. When he does consent it cannot appropriately be said that there is a strike or concerted refusal to handle goods on the part of the employees. Congress has not seen fit to protect these other persons or the general public by any wholesale condemnation of secondary boycotts, since if the secondary employer agrees to the boycott, or it is brought about by means other than those proscribed in § 8(b)(4)(A), there is no unfair labor practice.

It is relevant to recall that the Taft-Hartley Act was, to a marked degree, the result of conflict and compromise between strong contending forces and deeply held views on the role of organized labor in the free economic life of the Nation and the appropriate balance to be struck between the uncontrolled power of management and labor to further their respective interests. This is relevant in that it counsels wariness in finding by construction a broad policy against secondary boycotts as such when, from the words of the statute itself, it is clear that those interested in just such a condemnation were unable to secure its embodiment in enacted law. The problem raised by these cases affords a striking illustration of the importance of the truism that it is the business of Congress to declare policy and not this Court's. The judicial function is confined to applying what Congress has enacted after ascertaining what it is that Congress has enacted. But such ascertainment, that is, construing legislation, is nothing like a mechanical endeavor. It could not be accomplished by the subtlest of modern 'brain' machines. Because of the infirmities of language and the limited scope of science in legislative drafting, inevitably there enters into the construction of statutes the play of judicial judgment within the limits of the relevant legislative materials. Most relevant, of course, is the very language in which Congress has expressed its policy and from which the Court must extract the meaning most appropriate. Of course § 8(b)(4)(A), like the entire Taft-Hartley Act, was designed to protect the public interest, but not in the sense that the public was to be shielded from secondary boycotts no matter how brought about. Congress' purpose was more narrowly conceived. It aimed to restrict the area of industrial conflict insofar as this could be achieved by prohibiting the most obvious, widespread, and, as Congress evidently judged, dangerous practice of unions to widen that conflict: the coercion of neutral employers, themselves not concerned with a primary labor dispute, through the inducement of their employees to engage in strikes or concerted refusals to handle goods. In the light of the purpose of the statute as thus defined the cases now before the Court must be judged.

The question is whether a hot cargo provision, such as is found in the collective bargaining agreements in these cases, can be a defense to a charge of an unfair labor practice under § 8(b)(4)(A) when, in the absence of such a provision, the union conduct would unquestionably be a violation. This question has had a checkered career in the decisions of the National Labor Relations Board since it first came before that tribunal some nine years ago. In the Conway's Express case, in re International Brotherhood of Teamsters, 1949, 87 N.L.R.B. 972, affirmed sub nom. Rabouin v. National Labor Relations Board, 2 Cir., 195 F.2d 906, the Board (Members Houston, Murdock, and Gray) found that there was nothing in a hot cargo provision as such repugnant to the policy of the statute, and that the union had not violated § 8(b)(4)(A) when, pursuant to the provision, it had instructed employees not to handle goods, and the employers had apparently acquiesced. Chairman Herzog concurred in the finding that § 8(b)(4)(A) had not been violated on the facts of the particular case, but was of the opinion that the hot cargo provision did not license the union itself to take action to induce the employees to refuse to handle goods. 87 N.L.R.B. at page 983 note 33. Member Reynolds dissented on the ground that a hot cargo provision was in conflict with the policy of the statute and could not be invoked as a defense to a charge of a violation of § 8(b)(4)(A). In the Pittsburgh Plate Glass case, Chauffeurs Union, 1953, 105 N.L.R.B. 740, where the union had also induced employees not to handle goods and the employers had acquiesced in the enforcement of the hot cargo provisions, the Board without dissent (Memebers Houston, Murdock, Styles and Peterson; Chairman Herzog took no part) adhered to the Conway decision. Since 'the employers in this proceeding consented to the 'unfair goods' provision of the contracts, their employees' failure to handle these goods was not a strike or concerted refusal to work under Section 8(b)(4)(A).' 105 N.L.R.B. at page 744.

In the McAllister case, International Brotherhood of Teamsters, 1954, 110 N.L.R.B. 1769, the Board took a different position. Members Rodgers and Beeson were of the view that § 8(b)(4)(A) prohibited all secondary boycotts and had been enacted as much for the protection of the primary employer and the public as the secondary employers, and that a contract between the secondary employers and the union was ineffective to waive the protection granted these other interests. They called for overruling the Conway case and a declaration that a hot cargo provision is no defense to a charge under § 8(b)(4)(A). Chairman Farmer concurred in finding a violation of the statute, on the ground that the case was distinguishable from the Conway and Pittsburgh Plate Glass decisions in that the employers had not acquiesced in the employees' failure to handle the goods. He found nothing contrary to the statute in the execution of a hot cargo provision and mutual adherence to it by employer and union, but only in the inducement of employees to refuse to handle goods in the face of express instructions to do so. Members Murdock and Peterson dissented on the ground that since the employers had by the hot cargo provision consented in advance to the boycott, there was no strike or concerted refusal to handle goods within the meaning of the statute, apparently even assuming that the employers had instructed their employees to handle the goods.

Still further mutations in the position of the Board and the views of the individual members took place in the Sand Door case, Local 1976, United Brotherhood of Carpenters, 1955, 113 N.L.R.B. 1210, now here as No. 127. Chairman Farmer and Member Leedom maintained that, although hot cargo clauses are not themselves in conflict with the statute, any direct appeal by a union to the employees of a secondary employer to induce them to refuse to handle goods, and in this manner to assert their rights under the contract, violates § 8(b)(4)(A). The importance of the fact that, evidently, the employer in the case before the Board had not acquiesced in the stoppage was not made clear. Member Rodgers concurred in the result on the basis of the principal opinion in the McAllister case and his view that hot cargo clauses as such violate the policy of the statute. Members Murdock and Peterson, dissenting, adhered to the views they had expressed in McAllister. See also Local 11, United Brotherhood of Carpenters (General Millwork Corp.), 113 N.L.R.B. 1084, 1086-1087, and Members Murdock and Peterson dissenting at pages 1088-1090, affirmed sub nom. National Labor Relations Board v. Local 11, United Brotherhood of Carpenters, 6 Cir., 242 F.2d 932.

In the American Iron case, General Drivers Union, 1956, 115 N.L.R.B. 800, now here as Nos. 273 and 324, Members Leedom and Bean relied on the principal opinion in the Sand Door case, making it clear that any direct appeal to the employees was forbidden whether or not the employer acquiesced in the boycott. Member Rodgers concurred on the basis of his previous opinions. Members Murdock and Peterson dissented, noting that since there was a violation of the statute even if the employer acquiesced, the Conway doctrine had at last been clearly repudiated. See also Milk Drivers Union (Crowley's Milk Co.), 1956, 116 N.L.R.B. 1408, orders reversed and enforcement denied sub nom. Milk Drivers & Dairy Emp. Local Union, etc., v. National Labor Relations Board, 2 Cir., 245 F.2d 817.

In a decision handed down after the granting of certiorari in the cases now before the Court, Truck Drivers Union (Genuine Parts Co.), 1957, 119 N.L.R.B. 399, two members of the Board, Chairman Leedom and Member Jenkins, rested on a broader ground than that taken in the principal opinion in the Sand Door and American Iron cases: when the secondary employer is a common carrier subject to the Interstate Commerce Act, 24 Stat. 379, as amended by Act of Aug. 9, 1935, 49 Stat. 543, amended, 49 U.S.C. §§ 301-327, 49 U.S.C.A. §§ 301-327, a hot cargo clause is invalid at its inception and cannot be recognized by the Board as having any force or effect. It is also strongly suggested in the opinion filed by these members that it would be desirable to establish such a rule in respect to all employers, and that the mere existence of a hot cargo clause should be deemed prima facie evidence of inducement in violation of § 8(b)(4) (A). Member Rodgers concurred on the basis of his earlier opinions, without considering the implications of the Interstate Commerce Act. Member Bean concurred solely on the basis of the Sand Door case. Member Murdock dissented, objecting particularly to what he conceived to be the extreme suggestion that the mere existence of a hot cargo provision should be deemed prima facie evidence of a violation of § 8(b)(4)(A), and pointing out that a majority of the Board appears to have abandoned the theory of the Sand Door and American Iron cases even before this Court could review them.

The argument that a hot cargo clause is a defense to a charge of a violation of § 8(b)(4)(A) may be thus stated. The employer has by contract voluntarily agreed that his employees shall not handle the goods. Because of this consent, even if it is sought to be withdrawn at the time of an actual work stoppage and boycott, it cannot be said, in the light of the statutory purpose, either that there is a 'strike or a concerted refusal' on the part of the employees, or that there is a 'forcing or requiring' of the employer. Only if consideration is confined to the circumstances immediately surrounding the boycott, in disregard of the broader history of the labor relations of the parties, is it possible to say that the employer is coerced into engaging in the boycott. If the purpose of the statute is to protect neutrals from certain union pressures to involve them involuntarily in the labor disputes of others, protection should not extend to an employer who has agreed to a hot cargo provision, for such an employer is not in fact involuntarily involved in the dispute. This must at least be so when the employer takes no steps at the time of the boycott to repudiate the contract and to order his employees to handle the goods. The union does no more than inform the employees of their contractual rights and urge them to take the only action effective to enforce them.

The Board in the present cases has rejected the argument as not comporting with the legislative purpose to be drawn from the statute, projected onto the practical realities of labor relations. We agree, duly heedful of the strength of the argument to the contrary. There is nothing in the legislative history to show that Congress directly considered the relation between hot cargo provisions and the prohibitions of § 8(b)(4)(A). Nevertheless, it seems most probable that the freedom of choice for the employer contemplated by § 8(b)(4) (A) is a freedom of choice at the time the question whether to boycott or not arises in a concrete situation calling for the exercise of judgment on a particular matter of labor and business policy. Such a choice, free from the prohibited presures-whether to refuse to deal with another or to maintain normal business relations on the ground that the labor dispute is no concern of his-must as a matter of federal policy be available to the secondary employer notwithstanding any private agreement entered into between the parties. See National Licorice Co. v. National Labor Relations Board, 309 U.S. 350, 364, 60 S.Ct. 569, 577, 84 L.Ed. 799. This is so because by the employer's intelligent exercise of such a choice under the impact of a concrete situation when judgment is most responsible, and not merely at the time a collective bargaining agreement is drawn up covering a multitude of subjects, often in a general and abstract manner, Congress may rightly be assumed to have hoped that the scope of industrial conflict and the economic effects of the primary dispute might be effectively limited.

Certainly the language of the statute does not counter such an interpretation. The employees' action may be described as a 'strike or concerted refusal,' and there is a 'forcing or requiring' of the employer, even though there is a hot cargo provision. The realities of coercion are not altered simply because it is said that the employer is forced to carry out a prior engagement rather than forced now to cease doing business with another. A more important consideration, and one peculiarly within the cognizance of the Board because of its closeness to and familiarity with the practicalities of the collective bargaining process, is the possibility that the contractual provision itself may well not have been the result of choice on the employer's part free from the kind of coercion Congress has condemned. It may have been forced upon him by strikes that, if used to bring about a boycott when the union is engaged in a dispute with some primary employer, would clearly be prohibited by the Act. Thus, to allow the union to invoke the provision to justify conduct that in the absence of such a provision would be a violation of the statute might give it the means to transmit to the moment of boycott, through the contract, the very pressures from which Congress has determined to relieve secondary employers.

Thus inducements of employees that are prohibited under § 8(b)(4)(A) in the absence of a hot cargo provision are likewise prohibited when there is such a provision. The Board has concluded that a union may not, on the assumption that the employer will respect his contractual obligation, order its members to cease handling goods, and that any direct appeal to the employees to engage in a strike or concerted refusal to handle goods is proscribed. This conclusion was reached only after considerable experience with the difficulty of determining whether an employer has in fact acquiesced in a boycott, whether he did or did not order his employees to handle the goods, and the significance of an employer's silence. Of course if an employer does intend to observe the contract, and does truly sanction and support the boycott, there is no violation of § 8(b)(4)(A). A voluntary employer boycott does not become prohibited activity simply because a hot cargo clause exists. But there remains the question whether the employer has in fact truly sanctioned and supported the boycott, and whether he has exercised the choice contemplated by the statute. The potentiality of coercion in a situation where the union is free to approach the employees and induce them to enforce their contractual rights by self-help is very great. Faced with a concerted work stoppage already in progress, an employer may find it substantially more difficult than he otherwise would to decide that business should go on as usual and that his employees must handle the goods. His 'acquiescence' in the boycott may be anything but free. In order to give effect to the statutory policy, it is not unreasonable to insist, as the Board has done, that even when there is a contractual provision the union must not appeal to the employees or induce them not to handle the goods. Such a rule expresses practical judgment on the effect of union conduct in the framework of actual labor disputes and what is necessary to preserve to the employer the freedom of choice that Congress has decreed. On such a matter the judgment of the Board must be given great weight, and we ought not set against it our estimate of the revelant factors.

There is no occasion to consider the invalidity of hot cargo provisions as such. The sole concern of the Board in the present cases was whether the contractual provision could be used by the unions as a defense to a charge of inducing employees to strike or refuse to handle goods for objectives proscribed by § 8(b)(4)(A). As we have said, it cannot be so used. But the Board has no general commission to police collective bargaining agreements and strike down contractual provisions in which there is no element of an unfair labor practice. Certainly the voluntary observance of a hot cargo provision by an employer does not constitute a violation of § 8(b)(4)(A), and its mere execution is not, contrary to the suggestion of two members of the Board in the Genuine Parts case, Truck Drivers Union, 119 N.L.R.B. 399, prima facie evidence of prohibited inducement of employees. It does not necessarily follow from the fact that the unions cannot invoke the contractual provision in the manner in which they sought to do so in the present cases that it may not, in some totally different context not now before the Court, still have legal radiations affecting the relations between the parties. All we need now say is that the contract cannot be enforced by the means specifically prohibited in § 8(b)(4) (A).

In Nos. 273 and 324, the Board in its brief suggests that we should go further and find that the contract provisions in these cases are invalid as such because the secondary employers are common carriers subject the Interstate Commerce Act, 24 Stat. 379, as amended by Act of Aug. 9, 1935, 49 Stat. 543, amended, 49 U.S.C. §§ 301-327, 49 U.S.C.A. §§ 301-327. In the recent Genuine Parts case, already referred to, Truck Drivers Union, 119 N.L.R.B. 399, two members of the Board in fact took this position, stating that when common carriers are involved hot cargo clauses are 'invalid at their inception and can be given no operative cognizance so far as the administration of this (the Labor Management Relations) Act is concerned.' This is true, it is said, because by entering a contract not to handle the goods the carrier violates its obligations under the Interstate Commerce Act to provide nondiscriminatory service and to observe just and reasonable practices. See Act of Aug. 9, 1935, § 216, 49 Stat. 558, amended, 49 U.S.C. § 316, 49 U.S.C.A. § 316. The carrier's consent to boycott is therefore void, and it follows that it is likewise void for all purposes concerned with the Labor Management Relations Act. Since the Genuine Parts decision was handed down, the Interstate Commerce Commission has in fact ruled, in Galveston Truck Line Corp. v. Ada Motor Lines, Inc., 73 M.C.C. 617 (Dec. 16, 1957), that the carriers there involved were not relieved from their obligations under the Interstate Commerce Act by a hot cargo clause.

It is significant to note the limitations that the Commission was careful to draw about its decision in the Galveston case. It was not concerned to determine, as an abstract matter, the legality of hot cargo clauses, but only to enforce whatever duty was imposed on the carriers by the Interstate Commerce Act and their certificates. The Commission recognized that it had no general authority to police such contracts, and its sole concern was to determine whether a hot cargo provision could be a defense to a cargo that the carriers had violated some specific statutory duty. It is the Commission that in the first instance must determine whether, because of certain compelling considerations, a carrier is relieved of its usual statutory duty, and necessarily it makes this determination in the context of the particular situation presented by the case before it. Other agencies of government, in interpreting and administering the provisions of statutes specifically entrusted to them for enforcement, must be cautious not to complicate the Commission's administration of its own act by assuming as a fixed and universal rule what the Commission itself may prefer to develop in a more cautious and pragmatic manner through case-by-case adjudication.

But it is said that the Board is not enforcing the Interstate Commerce Act or interfering with the Commission's administration of that statute, but simply interpreting the prohibitions of its own statute in a way consistent with the carrier's obligations under the Interstate Commerce Act. Because of that Act a carrier cannot effectively consent not to handle the goods of a shipper. Since the cannot effectively consent, there is, under § 8(b)(4)(A), a 'strike or concerted refusal,' and a 'forcing or requiring' of the carrier to cease handling goods just as much as if no hot cargo clause existed. But the fact that the carrier's consent is not effective to relieve him from certain obligations under the Interstate Commerce Act does not necessarily mean that it is ineffective for all purposes, nor should a determination under one statute be mechanically carried over in the interpretation of another statute involving significantly different considerations and legislative purposes. Whether a carrier has without justification failed to provide reasonable and nondiscriminatory service is a question of defining the carrier's duty in the framework of the national transportation policy. Whether there is a 'strike or concerted refusal,' or a 'forcing or requiring' of an employer to cease handling goods is a matter of the federal policy governing labor relations. The Board is not concerned with whether the carrier has performed its obligations to the shipper, but whether the union has performed its obligation not to induce employees in the manner proscribed by § 8(b)(4)(A). Common factors may emerge in the adjudication of these questions, but they are, nevertheless, distinct questions involving independent considerations. This is made clear by a situation in which the carrier has freely agreed with the union to engage in a boycott. He may have failed in his obligations under the Interstate Commerce Act, but there clearly is no violation of § 8(b)(4)(A); there has been no prohibited inducement of employees.

The case is not like that in Southern S.S.C.o. v. National Labor Relations Board, 316 U.S. 31, 62 S.Ct. 886, 86 L.Ed. 1246, where the Board was admonished not to apply the policies of its statute so single-mindedly as to ignore other equally important congressional objectives. A specific remedy ordered by the Board reinstatement of employees who had engaged in a strike-worked directly to weaken the effectiveness of a statutory prohibition against mutiny by members of the crew of a vessel. Presumed illegality under the mutiny statute was not used to establish a violation of the labor statute. It was relied on to establish an abuse of discretion in giving a remedy. Much less was there any suggestion that the Board should abandon an independent inquiry into the requirements of its own statute and mechanically accept standards elaborated by another agency under a different statute for wholly different purposes.

The unions in Nos. 273 and 324 violated § 8(b)(4)(A) for the reasons set forth in the first part of this opinion, and not as a consequence of prohibitions in the Interstate Commerce Act.

The judgments in Nos. 127 and 324 are affirmed. The judgment in No. 273 is reversed and the cause remanded to the Court of Appeals with instructions to grant enforcement of the order of the Board.

Nos. 127 and 324-Affirmed.

No. 273-Reversed and remanded.
