"The penal law ordinance of 4 December 1941 concerning Poles was intended not only to serve as a criminal law against Poles and Jews, but beyond that also to provide general principles for the German administration of law to adopt in all its judicial dealings with Poles and Jews, irrespective of the role which the Poles and Jews play in the individual proceedings. The regulations of article IX for instance, according to which Poles and Jews are not to be sworn in, apply to proceedings against Germans as well. * * *

"1. Proceedings against Germans should be carried on whenever possible without calling Poles and Jews as witnesses. If, however, such a testimony cannot be evaded, the Pole or Jew must not appear as a witness against the German during the main trial. He must always be interrogated by a judge who has been appointed or requested to do so, * * *.

" 2. Evidence given by Poles and Jews during proceedings against Germans must be received with the utmost caution especially in those cases where other evidence is lacking." 

"With a view to freeing the German people of Poles, Russians, Jews, and gypsies, and with a view to making the eastern territories which have been incorporated into the Reich available for settlements for German nationals, I intend to turn over criminal proceedings against Poles, Russians, Jews, and gypsies to the Reich Leader SS. In so doing I base myself on the principle that the administration of justice can only make a small contribution to the extermination of members of these peoples. The justice administration undoubtedly pronounces very severe sentences on such persons, but that is not enough to constitute any material contribution toward the realization of the above-mentioned aim."
