Joseph P. Bradley, Robertson v. Frank Brothers Company…
“ If they didn't pay any more than they ought to, transportation or labor charges,-then the verdict is for the defendant.'Under this charge, of course, the jury, in finding for the plaintiffs, must have found that they acted under constraint-under moral duress-in making the additions for transportation and labor. We do not see how the verdict can be set aside for error in the charge on this point, unless the law be that virtual or moral duress is insufficient to prevent a payment made under its influence from being voluntary. ”
