The English language Wikipedia article on the Dirlewanger Brigade in Belarus quotes Martin Kitchen, The Third Reich: Charisma and Community, p. 267, stating that the unit:
committed such shocking atrocities in the Soviet Union, in the pursuit of partisans, that even an SS court was called upon to investigate
In contemporary history, we consider that Nazi war crimes, in particular Waffen SS (but also Wehrmacht) crimes in central and eastern Europe, are the epitome of war crime atrocities. I was therefore somewhat surprised to read that an SS court would investigate atrocities committed against citizens of Nazi occupied territories, because I cannot imagine what may constitute going "too far" and that the SS effectively was given a free hand to do as it pleased. Although the article does not state any ruling of the SS court, I suppose Dirlewanger was acquitted or it would have said otherwise. On the other hand, if not even Oskar Dirlewanger was convicted then probably nobody was.
Are there any documented cases of where SS or other Nazi courts having convicted any soldiers, officers, or otherwise, for atrocities / war crimes that went "too far" even by the standards of the SS / Nazi?
