According to Hans Martin Sutermeister, a Bern doctor bent on exposing courtroom injustices, the verdict was nothing more than a miscarriage of justice, whose main cause was inadequate forensic expertise. Sutermeister described Hegg as "an autodidact without a basic education, who had already been wrong more often". Sutermeister, convinced of Jaccoud's innocence, believed that he had known that Baud was no longer dating André Zumbach and that Zumbach had been murdered because he supplied Algerian rebels with $12,000 worth of dud explosives. He pointed out that "Reymond" and his arms dealer friends, unbeknownst to Zumbach, also kept knives and bayonets in the garage, one of which could have been the murder weapon. Sutermeister spent considerable time attempting to show that Jaccoud's conviction was a result of forensic "dilettantism". Hegg had been censured for confusing human and pig's blood in a previous investigation, and had been defended on that occasion by Jaccoud – who had difficulty getting him to pay his fee. At one point Hegg sued Sutermeister for defamation. But he was not alone in disputing the verdict. Horace Mastronardi called it "the greatest judicial error of the post-war years". He and other lawyers tried to have it reversed for "more than twenty years".
