Vollmer wrote his doctoral dissertation in 1926 on "The Development and Contemporary Meaning of Hostageship: a Study in International Law" at the University of Cologne.
[2] His new position, however, brought him into conflict with the Oberlandesgericht district president, and the Ministry of Justice, with the approval of Hermann Göring, transferred him to the public prosecutor's office in Stendal in 1934.
[9] Summarizing the kind of behavior that justified the death penalty according to 1943-1944 jurisprudence, Dr. Vollmer wrote, "No longer tolerable and fundamentally worthy of death are [...] remarks of the following kind: The war is lost; Germany or the Führer picked a fight and senselessly or frivolously started the war and must lose it; the NSDAP should or will relinquish power and, like the Italian model, make way for the understanding of peace; a military dictatorship must be established and will be able to forge peace, one must work slowly in order to bring about the conclusion; an intrusion of bolshevism would not be as bad as the propaganda paints it, and will only harm the leading National Socialists; the English or the Americans will stop bolshevism at the German border; urging by word of mouth or letters to the front to throw down their guns or turn back; the Führer is sick, incompetent, a butcher, etc.
"[10][note 1] On November 18, 1944, Vollmer gave a lecture in Göttingen to the National Socialist Lawyers' Association with Rudolf Smend (January 15, 1882 – July 5, 1975), a jurist and law professor.
[11] A letter sent to Vollmer by another Ministerial Director was used in the Nuremberg Trials to show that judges were not just guided by the executive branch, but were also spied on by Adolf Hitler's government.
