The leaders of the German Wehrmacht would have neglected their duty if confronted with these facts, had they not attempted to solve, at any price, the problem as to which chemical preparations were capable of preventing bacterial wound infection and, above all, gas gangrene, and also whether effective means could be found at all. Whatever the answer to this question was, it had to be found as soon as possible in order to avert an imminent danger and to throw light on a question which was important to the individual wounded soldier as well as to the striking power of the whole army. After the failure of all attempts to solve the problem through clinical observation of incidental wounds and other methods, and, in view of the particularly difficult situation and especially of the time factor, there was nothing left but to decide the question through an experiment on human beings. The responsible leaders of the German Wehrmacht did not hesitate to draw the conclusions resulting from this situation, and the head of the German Reich, who was at the same time Commander in Chief of the German Wehrmacht, gave orders for a final solution of this problem by way of large scale experimentation. Let us examine the legal conclusions to be drawn from this situation as it existed in 1942 for the German Wehrmacht and therefore for the German state—in particular regarding the assumption of an existing national emergency. The problem of emergency and the specific case of self-defense has been regulated in almost all criminal codes in a way applicable only to individual cases. The individual is granted impunity under certain conditions when “acting in an individual emergency arising for himself or others”. The administration of justice and legal literature, however, recognize that even the commonwealth, the “state,” can find itself in an emergency, and that acts which are meant to and actually do contribute to overcome this emergency may be exempt from punishment. 1. First of all, the question has been raised whether the conception of self-defense, conceived to cover individual cases, can be extended to include a state self-defense, meaning a self-defense for the benefit of the state and the commonwealth. The answer to this question was a unanimous affirmative. 2. The same reasoning, however, as applied to self-defense is also applicable to the conception of an emergency, as embodied, for example, in Section 54 of the German Penal Code and in almost all modern systems of penal law. These provisions, too, were originally conceived to cover individual cases. But, using them as a starting point, legal literature and the administration of justice arrive at a recognition in principle of a national emergency with a corresponding effect. With regard to the definition of the concept of an emergency generally given in the penal laws, the application of these provisions to the state, while justified in itself, can only be effected in principle.
