The problem, however, was the uncertainty in determining to what amount those damages should total. The petitioners submitted two methodologies for calculating damages. The first was the yardstick method, which compared the earnings from petitioner's theater, Jackson Park, during the conspiracy to the earnings of its competitor, the Maryland Theater. The two theaters were comparable in size, although the Jackson Park theater was "superior in location, equipment, and attractiveness to patrons." The Maryland Theater, however, was owned by Paramount Pictures, and benefited from the conspiracy. The evidence showed that during the five-year period, Maryland's profit exceeded petitioner's like profit by $115,982.34. The second measure was the before & after method. Here, the Court looked to the years 1933-1937, where the petitioner had successfully showed at least some first run movies, to the five-year period where the conspiracy was established to have happened, and petitioner was completely shut out of first run movies despite its best efforts. This comparison showed a falling off of petitioners' profits during the five-year period aggregating $125,659.00. The 7th Circuit concluded that the jury had adopted the before & after method, but that this proof did not furnish a proper measure of damage for the reason that it could not be proved what petitioner's earnings would have been in the absence of the illegal distribution of films. The Supreme Court reversed, holding that a damage award does not need to be mathematically precise, but it must be a just and reasonable estimate based on the evidence presented, and not based on speculation. Petitioners are able to submit yardstick or before & after estimates, but they must be careful to use comparable data.
