The court concluded that the rule in Summers was not applicable here. In Summers, all the parties who could have been responsible for the harm to the plaintiff were joined as defendants. Here, only five out of 200 DES manufacturers were defendants in the suit.
The second exception is the "concert of action"
theory, as embodied in 876 ofRestatement (Second) of Torts:
For harm resulting to a third person from the tortious conduct of another, one is subject to liability if he
(a) does a tortious act in concert with the other or pursuant to a common design with him. or
(b) knows that the other's conduct constitutes a breach of duty and gives substantial assistance or encouragement to the other so to conduct himself, or
(c) gives substantial assistance to the other in accomplishing a tortious result and his own con duct, separately considered, constitutes a breach of duty to the third person. The plaintiff's complaint alleged that, by relying upon each other's testing and promotion methods, the defendants acted in pursuance of a common plan
or design to commit a tortious act. The court
concluded that such reliance is common practice in
the industry.
`
The problem with this theory is that applying
the "concert of action" to this situation would
render almost any manufacturer liable for the defec
tive product ofan entire industry. Furthermore--as
the court recognized in rejecting this theory there
was no allegation that each defendant knew the
other defendant's conduct was tortious and that
they encouraged one another to test and warn
inadequately with regard to use of DES.
The third exception is the theory which the
plaintiffs called enterprise liability. The court, how
ever, more accurately referred to it throughout as
"industry-wide liability." The former is really a
policy argument to impose liability; the latter states
the theory or cause of action itself. The theory was
suggested in Hall v. E. I. du Pont de Nemours A Co.,
