The trial featured testimony from psychologist Harry Hollingworth who examined the effects of caffeine on mental function. Although the research was funded by the Coca-cola company, Hollingworth had several stipulations in his contract including the right to publish his results, regardless of their outcome.
Coca-cola would be acquitted of the charges on June 13, 1914.
