Massachusetts Supreme Judicial Court January 11, 1968 (Doran v. A. B. Maddison Co.)

On the record of this case as it has reached us it is impossible to determine whether there was liability on the part of any of the defendants, for all of whom the judge directed verdicts at the conclusion of the evidence. The evidence left it wholly a matter of conjecture whether any defendant was responsible for an alleged window defect which caused the injury to the plaintiff.
