Sometime during 1947, Pernkopf is released by the Austrian authorities after his war-time status is changed from “incriminated person to lesser incriminated person.” During this time, Pernkopf tries to revise his personal history. In an interview while detained by the Austrian authorities, he greatly downplayed his involvement with the Nazi’s. For example, he admitted to joining the SA in 1933, but denied that he would have paid dues during the time when the SA was prohibited in Austria. This was common of Nazi officials who would try to downplay their involvement in the NSDAP after the war.
