United States v. E. C. Knight Co.
The Supreme Court ruled that the federal government could not use the Sherman Antitrust Act to undo a sugar company's takeover of nearly all U.S. sugar refineries, because the takeover was a monopoly over manufacturing, not over interstate trade itself.
The decision drew a sharp line between manufacturing goods and shipping or selling them across state lines, holding that Congress's power to regulate interstate commerce did not reach the making of goods within a single state, even when that making created a nationwide monopoly.
“Commerce succeeds to manufacture, and is not a part of it.”
The majority's key distinction separating manufacturing from interstate commerce.
How it got here: A federal trial court dismissed the government's suit, the Third Circuit Court of Appeals affirmed, and the government appealed to the Supreme Court.
The Case in Depth
What happened
The American Sugar Refining Company bought stock in four Philadelphia sugar refineries using its own shares, giving it control over roughly 98% of sugar refining in the United States. The federal government sued to cancel these stock purchases and stop the arrangement, arguing the deal violated the newly enacted Sherman Antitrust Act by creating a monopoly and restraining interstate trade in refined sugar.
The question before the Court
Could the federal government use the new antitrust law to break up a company's near-total control of sugar manufacturing, even though the deal itself only involved buying stock in Pennsylvania refineries?
Why it matters
The ruling meant the federal government's brand-new antitrust law could not touch manufacturing monopolies, only trade that crossed state lines. This left many industrial trusts largely beyond federal reach for years, forcing plaintiffs and prosecutors to prove a direct effect on interstate commerce rather than merely control over production of a good.
What changes now
The decree dismissing the government's suit was affirmed, meaning the sugar company's control over refining stood undisturbed. This was a final merits decision that established a durable manufacturing-versus-commerce distinction limiting the reach of the Sherman Antitrust Act for years afterward, until later cases and eventually different constitutional approaches expanded what counted as interstate commerce.
What this does not decide
The Court did not decide that the Sherman Act was unconstitutional, only that this particular transaction -- a stock purchase affecting manufacturing -- fell outside the Act's reach. It left open whether combinations that directly restrained the buying, selling, or transporting of goods across state lines could still be reached by the statute.
Concurrences and dissents
Dissent — Justice Harlan
Justice Harlan argued that buying and selling goods intended for interstate shipment is itself part of interstate commerce, not merely something that precedes it, so a combination that controls prices and purchases of an article destined for other states directly restrains interstate trade. He contended the sugar combination's near-total control of refining and pricing was itself a direct restraint on interstate commerce and that Congress had power under the Sherman Act to suppress it, and he would have declared the combination an unlawful restraint and enjoined it from continuing.
How the Court got there
The legal reasoning, step by step
- The Court framed the dispute around a distinction between manufacturing and commerce: manufacturing is the process of transforming raw materials into finished goods, while commerce is the buying, selling, and transporting of goods, and the two are legally separate activities even though one often leads to the other.
- Because the Constitution gives Congress exclusive power over interstate commerce but leaves control over manufacturing, production, and other local business activity to the states' own police power (their authority to regulate for health, safety, and morals), the Court had to decide which category the sugar company's stock purchases fell into.
- The Court reasoned that a monopoly over manufacturing sugar only affects interstate commerce indirectly and secondarily, since selling and shipping the sugar happens only after and separately from the act of making it; an indirect effect on commerce, however large, is not the same as directly restraining commerce itself.
- Applying this distinction, the Court held that the contracts at issue -- purchases of refinery stock -- related only to acquiring control of manufacturing facilities in Pennsylvania, and did not themselves restrain or monopolize the buying, selling, or transporting of sugar across state lines.
- Because the Sherman Act, as Congress wrote it, only reached contracts and combinations that restrain trade or commerce among the states, and not monopolies in manufacturing as such, the Court concluded that the statute simply did not authorize a court to unwind this stock transaction, regardless of how much manufacturing power it concentrated.

Reaffirms Kidd v. Pearson (128 U.S. 1)
The Court relied on this case's rule that manufacturing intended for export is still local, not interstate, commerce.
Reaffirms Coe v. Errol (116 U.S. 517)
The Court used this case's rule about when goods begin their interstate journey to support its manufacturing/commerce line.
