For more than forty years, Rose Cipollone smoked between one and two packs of cigarettes a day. Upon her death from lung cancer, Rose’s husband, Antonio Cipollone, filed suit against Liggett Group, Inc., Lorillard, Inc., and Philip Morris, Inc., three of the leading firms in the tobacco industry, for the wrongful death of his wife. Many theories of liability and defenses were asserted in this decidedly complex and protracted litigation. One theory of liability claimed by Mr. Cipollone was breach of express warranty. It is uncontested that all three manufacturers ran multimedia ad campaigns that contained affirmations, promises, or innuendos that smoking cigarettes was safe. For example, ads for Chesterfield cigarettes boasted that a medical specialist could find no adverse health effects in subjects after six months of smoking. Chesterfields were also advertised as being manufactured with “electronic miracle” technology that made them “better and safer for you.” Another ad stated that Chesterfield ingredients were tested and approved by scientists from leading universities. Another brand, L&M, publicly touted the “miracle tip” filter, claiming it was “just what the doctor ordered.” At trial, the defendant tobacco companies were not permitted to try to prove that Mrs. Cipollone disbelieved or placed no reliance on the advertisements and their safety assurances. Did the defendants breach an express warranty to the plaintiff? Explain.
