Federal Judge Owen, in denying Hiss's "coram nobis" petition, quoted verbatim two points made by Judge Goddard in denying Hiss's appeal for a new trial 30 years earlier, namely, that "there is not a trace of any evidence that Chambers had the mechanical skills, tools, equipment or material for such a difficult task typewriter forgery," and that "If Chambers had constructed a duplicate machine, how would he have known where to plant it so that it would be found by Hiss?"
