“Leaders, organizers, instigators, and accomplices participating in the formulation or execution of a Common Plan or Conspiracy to commit any of the foregoing crimes are responsible for all acts performed by any persons in execution of such plan.”

That, of course, is a statement of the ordinary law of conspiracy. The individual defendants are arraigned at your bar on this charge of conspiracy which, if proved, makes them responsible for the acts of others in execution of the common plan.

The Charter did not define responsibility for the acts of others in terms of “conspiracy” alone. The crimes were defined in nontechnical but inclusive terms, and embraced formulating and executing a common plan, as well as participating in a conspiracy. It was feared that to do otherwise might import into the proceedings technical requirements and limitations which have grown up around the term “conspiracy.” There are some divergencies between the Anglo-American concept of a conspiracy and that of either French, Soviet, or German jurisprudence. It was desired that concrete cases be guided by the broader considerations inherent in the nature of the problem I have outlined, rather than to be controlled by refinements of any local law.

Now, except for procedural difficulties arising from their multitude, there is no reason why every member of any Nazi organization accused here could not have been indicted and convicted as a part of the conspiracy under Article 6, even if the Charter had never mentioned organizations at all. To become voluntarily affiliated was an act of adherence to some common plan or purpose.

These organizations did not pretend to be merely social or cultural groups; admittedly, the members were united for action. In the case of several of the Nazi organizations, the fact of confederation was evidenced by formal induction into membership, the taking of an oath, the wearing of a distinctive uniform, the submission to a discipline. That all members of each Nazi organization did combine under a common plan to achieve some end by combined efforts is abundantly established.

The criteria for determining whether these ends were guilty ends are obviously those which would test the legality of any combination or conspiracy. Did it contemplate illegal methods or purpose illegal ends? If so, the liability of each member of one of these Nazi organizations for the acts of every other member is not essentially different from the liability for conspiracy enforced in the courts of the United States against businessmen who combine in violation of the anti-trust laws, or other defendants accused under narcotic-drugs acts, sedition acts, or other Federal penal enactments.

Among the principles every day enforced in courts of Great Britain and the United States in dealing with conspiracy are these sweeping principles:

No formal meeting or agreement is necessary. It is sufficient, although one performs one part and other persons other parts, if there be concert of action and working together understandingly with a common design to accomplish a common purpose.

Secondly, one may be liable even though he may not have known who his fellow conspirators were or just what part they were to take or what acts they committed, and though he did not take personal part in them or was absent when the criminal acts occurred.

Third, there may be liability for acts of fellow conspirators although the particular acts were not intended or anticipated, if they were done in execution of the common plan. One in effect makes a fellow conspirator his agent with blanket authority to accomplish the ends of the conspiracy.
