standards necessary for evaluating reasonableness.
6
Eventually, however, the
Court adopted the view that the Act banned only unreasonable restraints,
as measured under a rule of reason.
7
The Court later elaborated that the
application of the rule of reason required a searching analysis of the given
restraint and its context to determine whether, on balance, it “merely
regulates and perhaps thereby promotes competition or whether it is such
as may suppress or even destroy competition.”
8
Despite the adoption of the rule of reason as the baseline mode of
Section One analysis, courts began applying a rule of per se illegality to
certain types of restraints with clear anticompetitive potential throughout
the early part of the twentieth century.
9
Among the categories of restraints
held to be illegal per se during this period were horizontal price-fixing;
10
vertical agreements to set minimum prices,
11
maximum prices,
12
and non-
price restraints;
13
division of markets;
14
group boycotts;

and tying
arrangements.

The underlying judicial perception was that, on balance,
these types of restraints were so overwhelmingly likely to yield
anticompetitive versus procompetitive results that individual cases did not
merit an in-depth rule of reason analysis. Instead, courts deemed these
restraints to be per se anticompetitive.
Beginning in the 1970s, however, the immensely influential brand of
conservative economic theory known as the Chicago School called into
question the widespread use of the per se rule.
