Main Commissars are described in these terms:
“Upon recommendation by the Reich Commissar the Reich Minister for the Occupied Eastern Territories appoints Main Commissars for Main Districts formed by the consolidation of several Circuit Districts.” (1056-PS)
The order of superiority in the service among these various officials is stated as follows:
“The Reich Minister for the Occupied Eastern Territories is the service superior of the Reich Commissar and the officials and the employees subordinate to them. The Reich Commissar is the superior of all officials and employees of his office and of the offices subordinate to him. The General Commissar is the superior of the officials and employees of his office and of the officials and employees of the offices of the Main and Regional Commissars. The Main Commissar and the Regional Commissar are the superior of the officials and employees of their offices.” (1056-PS)
Thus, there is a continuous chain of command and of accountability from the Reich Minister, Rosenberg, down through each subdivision of the Ministry.
Furthermore, Rosenberg had authority to legislate for the entire area, and the jurisdiction of his Ministry was exclusive, aside from that of the military. The organizational treatise states:
“The Reich Commissars, General Commissars, Main Commissars and Regional Commissars (City Commissars) are—aside from the military agencies—the only Reich authorities [Reichsbehoerden] in the Occupied Eastern Territories. Other Reich authorities may not be established alongside them. They handle all questions of administration of the area which is subordinate to their sovereignty and all affairs which concern the organization and activity of the administration including those of the Police in the supervision of the native [landeseigenen] agencies and organizations, and of the population.
“The Reich Minister governs the occupied Eastern Territories by order of the Fuehrer. He can make the law for all the territories.” (1056-PS)
The following passage shows that the economic exploitation of the territory was undertaken in fullest cooperation with the Commissioner of the Four-Year Plan:
“The Fuehrer has entrusted Reich Marshal Hermann Goering, as Commissioner for the Four Year Plan, with the supervision of the tasks of the war economy in the Occupied Eastern Territories. The economic inspectorates and economic commands are active there as his representatives [Organe] [see Green Folio]. These economic inspectorates and economic commands will be substantially absorbed in the agencies of the civil administration after the establishment of the civil administration.” (1056-PS)
