''
Standard Oil Company of New Jersey v. United States.''
History
Upon its development some critics of ''Standard Oil'', including the lone dissenter Justice
John Marshall Harlan, argued that ''Standard Oil'' and its rule of reason were a departure from previous Sherman Act case law, which purportedly had interpreted the language of the Sherman Act to hold that all contracts restraining trade were prohibited, regardless of whether the restraint actually produced ill effects. These critics emphasized in particular the Court's decision in ''
United States v. Trans-Missouri Freight Association'', 166 U.S. 290 (1897), which contains some language suggesting that a mere restriction on the autonomy of traders would suffice to establish that an agreement restrained trade within the meaning of the Act.

Robert Heron Bork (March 1, 1927 – December 19, 2012) was an American legal scholar who served as solicitor general of the United States from 1973 until 1977. A professor by training, he was acting United States Attorney General and a judge on ...
, argued that the decision and the principle it announced was entirely consistent with earlier case law. These scholars argue that much language in ''Trans-Missouri Freight'' was dicta, and also emphasized the Court's decision in ''United States v. Joint Traffic Association'', 171 U.S. 505 (1898), in which the Court announced that "ordinary contracts and combinations" did not offend the Sherman Act, because they restrained trade only "indirectly". Indeed, in his 1912 book on antitrust law, Taft reported that no critic of ''Standard Oil'' could succeed in Taft's challenge: to articulate one scenario in which the rule of reason would produce a result different from that produced under prior case law. In 1911, the Supreme Court announced ''
United States v. American Tobacco Co.'', 221 U.S. 106 (1911). That decision held that Section 2 of the Sherman Act, which bans
monopolization, did not ban the mere possession of a monopoly but banned only the unreasonable acquisition or maintenance of monopoly. This reflects a long-standing view that one can have a monopoly just by having a superior product and that it violates no law to produce such a product.
In 1918, seven years later, the Court unanimously reaffirmed the rule of reason in ''
Chicago Board of Trade v. United States''. In an opinion written by Justice
Louis Brandeis
Louis Dembitz Brandeis ( ; November 13, 1856 – October 5, 1941) was an American lawyer who served as an Associate Justice of the Supreme Court of the United States, associate justice on the Supreme Court of the United States from 1916 to ...
, the Court held that an agreement between rivals limiting rivalry on price after an exchange was closed was reasonable and thus did not violate the
Sherman Act. The Court rejected a strict interpretation of the Sherman Act's language: "The true test of legality is whether the restraint imposed is such as merely regulates and perhaps thereby promotes competition or whether it is such as may suppress or even destroy competition." The Court did so mostly because the agreement was regulatory rather than anticompetitive.
The rule was narrowed in later cases that held that certain kinds of restraints, such as
price fixing
Price fixing is an anticompetitive agreement between participants on the same side in a market to buy or sell a product, service, or commodity only at a fixed price, or maintain the market conditions such that the price is maintained at a given ...

illegal per se
In US law, the term illegal ''per se'' means that the act is inherently illegal. Thus, an act is illegal without extrinsic proof of any surrounding circumstances such as lack of ''scienter'' (knowledge) or other defenses. Acts are made illegal '' ...
. These decisions followed up on the suggestion in ''Standard Oil'' that courts can determine that certain restraints are unreasonable based simply upon the "nature and character" of the agreement.
More recently, the Supreme Court has removed a number of restraints from the category deemed unlawful ''per se'' and instead subjected them to fact-based rule of reason analysis. These include non-price
vertical restraints in 1977's ''
Continental Television v. GTE Sylvania'', maximum
resale price maintenance
Resale price maintenance (RPM) or, occasionally, retail price maintenance is the practice whereby a manufacturer and its distribution (marketing), distributors agree that the distributors will sell the manufacturer's product at certain prices (re ...
agreements in 1997's ''
State Oil v. Khan'', and minimum resale price maintenance agreements in 2007's ''
Leegin Creative Leather Products, Inc. v. PSKS, Inc.''
Moreover, the Supreme Court has reaffirmed the conclusion in ''Standard Oil'' that analysis under the rule of reason should focus on the economic but not the social consequences of a restraint (''National Society of Professional Engineers v. United States'', 435 U.S. 679 (1978)). Further, the Court retained the ''per se'' rule against
tying contracts but raised the threshold showing of market power that plaintiffs must make to satisfy the rule's requirement of "economic power" (see ''
Jefferson Parish Hospital District No. 2 v. Hyde'', 466 U.S. 2 (1985).
Several authors have worked on the creation of a "structured rule of reason" so as to avoid the flaw in terms of the legal certainty surrounding a pure rule of reason.
In EU
A rule of reason does not exist in EU competition law (see e.g. T-11/08, T-112/99, T-49/02, T-491/07, T-208/13,
etc.).
It does, however, exist in the EU's substantive law, as developed in the European Court of Justice's ''
Cassis de Dijon''-ruling.
