While the Charter does not so provide, we think that on ordinary legal principles the burden of proof to justify a declaration of criminality is, of course, upon the Prosecution. It is discharged, we think, when we establish the following:
1. The organization or group in question must be some aggregation of persons associated in identifiable relationship with a collective, general purpose.
2. While the Charter does not so declare, we think it implied that membership in such an organization must be generally voluntary. This does not require proof that every member was a volunteer. Nor does it mean that an organization is not to be considered voluntary if the Defense proves that some minor fraction or small percentage of its membership was compelled to join. The test is a commonsense one: Was the organization on the whole one which persons were free to join or to stay out of? Membership is not made involuntary by the fact that it was good business or good politics to identify one’s self with the movement. Any compulsion must be of the kind which the law normally recognizes, and threats of political or economic retaliation would be of no consequence.
3. The aims of the organization must be criminal in that it was designed to perform acts denounced as crimes in Article 6 of the Charter. No other act would authorize conviction of an individual and no other act would authorize conviction of the organization in connection with the conviction of the individual.
4. The criminal aims or methods of the organization must have been of such a character that its membership in general may properly be charged with knowledge of them. This again is not specifically required by the Charter. Of course, it is not incumbent on the Prosecution to establish the individual knowledge of every member of the organization or to rebut the possibility that some may have joined in ignorance of its true character.
5. Some individual defendant must have been a member of the organization and must be convicted of some act on the basis of which the organization was declared to be criminal.
I shall now take up the subject of the issues, as we see it, which are for trial before this Tribunal, and some discussion of those which seem to us not to be for trial before this Tribunal.
Progress of this Trial will be expedited by a clear definition of the issues to be tried. I have indicated what we consider to be proper criteria of guilt. There are also subjects which we think are not relevant before this Tribunal, some of which are mentioned in the specific questions asked by the Tribunal.
Only a single ultimate issue is before this Tribunal for decision. That is whether accused organizations properly may be characterized as criminal ones or as innocent ones. Nothing is relevant here that does not bear on a question that would be common to the case of every member. Any matter that would be exculpating for some members but not for all is, as we see it, irrelevant here.
We think it is not relevant to this proceeding at this stage that one or many members were conscripted if in general the membership was voluntary. It may be conceded that conscription is a good defense for an individual charged with membership in a criminal organization, but an organization can have criminal purpose and commit criminal acts even if a portion of its membership consists of persons who were compelled to join it. The issue of conscription is not pertinent to this proceeding, but it is pertinent to the trials of individuals for membership in organizations declared to be criminal.
