delivered the opinion of the Court.
This suit was begun by a bill in equity filed in the District Court for the Eastern District of Missouri by the Herkert & Meisel Trunk Company and four others, all corporations of Missouri, engaged in making trunks and leather goods in St. Louis, against the United Leather Workers Union, Local Lodge or Union No. 66, an unincorporated association, its officers and agents and a number of its members. The bill averred that each of the complainants had built up a valuable business in making, selling and shipping in interstate commerce trunks and leather goods, that each received large quantities of raw material by interstate commerce, and employed a large
*462
number of persons, men and girls, that on February 28, 1920, defendants demanded that their shops be unionized and conducted as closed shops and announced that if complainants refused they would ruin the interstate commerce business of each of them, that on April 10,1920, the defendants, acting individually and on behalf of the defendant union, in order to destroy the complainants’ business and to prevent their employees from continuing in their employment unless complainants would yield to their demands, began a strike, assaulted and threatened complainants’ employees, and intimidated them so as to force them against their wills to quit complainants’ employment, and that they thereby prevented complainants from engaging in and carrying on their interstate business and interfered with and obstructed them in the manufacture and shipment of the products of their factories sold to be shipped in interstate commerce. The bill charged that defendants were carrying, out their illegal conspiracy and purposes by mass picketing and intimidation, that the interference with complainants’ interstate commerce was intentional and malicious and was intended to destroy it, that it was in violation of the Anti-Trust Law and the Clayton Act, and that they had already inflicted, and unless restrained would continue to inflict, irreparable injury upon such business. The bill shows that each complainant’s damage threatened exceeded three thousand dollars. The prayer was for a temporary and then a final injunction to prevent the intimidation, illegal picketing and other interference with complainants’ manufacturing and interstate business and with their employees or would-be employees engaged in carrying it on. Certain of the defendants answered the bill and denied the picketing, intimidation, and violence and the purpose to interfere with complainants’ interstate business as charged, and averred that they and the fellow members of the Union had lawfully quit the employment of complainants
*463
because they could not agree upon the terms of a new agreement. The- District Court upon preliminary hearing granted a temporary injunction and upon final hearing granted a final decree enjoining defendants as prayed. The case was taken on appeal to the Circuit Court of Appeals where the decree of the District Court was affirmed, one Judge dissenting.
The evidence adduced before the District Court showed that the defendant, the Local Union No. 66 of the United Leather Workers, having declared a strike against the complainants and withdrawn its members from their employ, instituted an illegal picketing campaign of intimidation against their employees who were willing to remain and against others willing to take the places of the striking employees, that the effect of this campaign was to prevent the complainants from continuing to manufacture their goods needed to fill the orders they had received from regular customers and would-be purchasers in other States, that such orders covered ninety per cent, of all goods manufactured by complainants, that the character of their business was known to the defendants, and that the illegal strike campaign of defendants thus interfered with and obstructed complainants’ interstate commerce business to their great loss. There was no evidence whatever to show that complainants were obstructed by the strike or the strikers in shipping to other States the products they had ready to ship or in their receipt of materials from other States needed to make their goods. While the bill averred that defendants had instituted a boycott against complainants and were prosecuting the same by illegal methods, there was no evidence whatever that any attempt was made to boycott the sale of the complainants’ products in other States or anywhere or to interfere with their interstate shipments of goods ready to ship.
*464 The sole question here is whether a strike against manufacturers by their employees, intended by the strikers to prevent, through illegal picketing and intimidation, continued manufacture, and having such effect, was a conspiracy to restrain interstate commerce under the Anti-Trust Act because such products when made were, to the knowledge of the strikers, to be shipped in interstate commerce to fill orders given and accepted by would-be purchasers in other States, in the absence of evidence that the strikers interfered or attempted to interfere with the free transport and delivery of the products when manufactured from the factories to their destination in other States, or with their sale in those States.
We think that this question has already been answered in the negative by this Court. In
United Mine Workers
v.
Coronado Co.,
*465 “ Coal mining is not interstate commerce, and the power of Congress does not extend to its regulation as such. In Hammer v. Dagenhart,247 U. S. 251 , 272, we said: ‘The making of goods and the mining of coal are not commerce, nor does the fact that these things are to be afterwards shipped or used in interstate commerce, make their production a part thereof. Delaware, Lackawanna & Western R. R. Co. v. Yurkonis,238 U. S. 439 .’ Obstruction to coal mining is not a direct obstruction to interstate commerce in coal, although, it, of course, may affect it by reducing the amount of coal to be carried in that commerce.” The same rule was followed in Gable v. Vonnegut Machinery Co.,274 Fed. 66 , 73, 74.
The same general principles are affirmed in
Heisler
v.
Thomas Colliery Co.,
The Circuit Court of Appeals seems first to have based its conclusion on cases like
Rearick
v.
Pennsylvania,
The Circuit Court of Appeals found further justification for its conclusion in cases like
Eureka Pipe Line Co.
v.
Hallanan,
In Lemke v. Farmers Grain Co., a state law of North Dakota subjected the purchase price of all grain flowing in a regular course of business from that State to the *467 market in Minneapolis, Minnesota, to a North Dakota inspector who was required to fix the price and determine thereby the profit the buyer should make after paying the freight to Minneapolis at the market price in that city. This was held to be a direct burden and restraint upon the interstate commerce in the grain from one State to the other. It was a direct limitation on that commerce.
None of these cases, although they all illustrate the practical conception of interstate commerce as a flowing stream from one State to another formed by a regular course of business, can properly be said to support the argument that mere intentional cutting down of manufacture or production is a direct restraint of commerce in the product intended to be shipped when ready, or to be any departure from the general rule last announced in the Coronado Case and uniformly applied in all the cases referred to above, which it followed. The effect upon interstate commerce in the four cases just cited on the other hand was directly burdensome and restraining.
Then the Circuit Court of Appeals found sustaining precedent in
Swift & Co.
v.
United States,
The case of the
Addyston Pipe Co.
v.
United States,
So in the case of
Montague & Co.
v.
Lowry,
On the'other hand,
Hopkins
v.
United States,
The
Knight Case
has been looked upon by many as qualified by subsequent decisions of this Court. The case is to be sustained only by the view that there was no proof of steps to be taken with intent to monopolize or restrain interstate commerce in sugar, but only proof of the acquisition of stock in sugar manufacturing companies to
*469
control its making. As intimated in the
Swift Case
(
In
Loewe
v.
Lawlor,
The cases of
Stafford
v.
Wallace,
*470 “ The reasonable fear by Congress that such acts, usually lawful and affecting only intrastate commerce when considered alone, will probably and more or less constantly be used in conspiracies against interstate commerce or constitute a direct and undue burden on it, expressed in this remedial legislation, serves the same purpose as the intent charged in the Swift indictment to bring acts of a similar character into the current of interstate commerce for federal restraint.”
In United States v. Patten, 226 U. S. 525, 543, running a corner in the available supply of a staple commodity, normally the subject of interstate commerce, in order to enhance its price artificially in the whole country, although the corner was carried on only in New York by sale of cotton futures, was held to be a monopoly of interstate commerce in violation of the Federal Anti-Trust Act. It was the intent to monopolize such commerce and its probability of success which sustained the indictment.
In the Coronado Case, supra, (p. 410), this Court referred to the Patten Case and the difference between that and the Coronado Case as follows:
“ The difference between the Patten Case and that of Ware & Leland v. Mobile County,209 U. S. 405 , illustrates a distinction to be drawn in cases which do not involve interstate commerce intrinsically but which may or may not be regarded as affecting interstate commerce so directly as to be within the federal regulatory power. In the Ware & Leland Case, the question was whether a State could tax the business of a broker dealing in contracts for the future delivery of cotton where there was no obligation to ship from one State to another. The tax was sustained and dealing in cotton futures was held not to be interstate commerce, and yet thereafter such dealings in cotton futures as were alleged in the Patten Case where they were part of a conspiracy to bring the entire cotton trade within its influence, were held to be in restraint of *471 interstate commerce. And so in the case at bar, coal mining is not interstate commerce and obstruction of coal mining, though it may prevent coal from going into interstate commerce, is not a restraint of that commerce unless the obstruction to mining is intended to restrain commerce in it or has necessarily such a direct, material and substantial effect to restrain it that the intent reasonably must be inferred.”
This review of the cases makes it clear that the mere reduction in the supply of an article to be shipped in interstate commerce, by the illegal or tortious prevention of its manufacture, is ordinarily an indirect and remote obstruction to that commerce. It is only when the intent or necessary effect upon such commerce in the article is to enable those preventing the manufacture to^ monopolize the supply, control its price or discriminate as between its would-be purchasers, that the unlawful interference with its manufacture can be said directly to burden interstate commerce.
The record is entirely without evidence or circumstances to show that the defendants in their conspiracy to deprive the complainants of their workers were thus directing their scheme against interstate commerce. It is true that they were, in this labor controversy, hoping that the loss of business in selling goods would furnish a motive to the complainants to yield to demands in respect to the terms of employment; but they did nothing which in any way directly interfered with the interstate transportation or sales of the complainants’ product.
We concur with the dissenting Judge in the Circuit Court of Appeals when, in speaking of the conclusion of the majority, he said: “ The natural, logical and inevitable result will be that every strike in any industry or even in any single factory will be within the Sherman Act and subject to federal jurisdiction provided any appreciable amount of its product enters into interstate -commerce.” (
*472 We can not think that Congress intended any such result in the enactment of the Anti-Trust Act or that the decisions of this Court warrant such construction.
Decree reversed.
