1. The situation at meeting of Council on 3rd April  will require very careful handling. You should keep in constant touch by telephone.
2. Your general aim should be to press for full enquiry into all facts affecting the disputes between Soviet Union and Persia, either by means of an investigation by the Council as a whole or by a Committee of which Australia is a member. During such an investigation documents should be called for and witnesses examined. No final decision of course should be taken by the Council until investigation is completed. investigation is essential whether Soviet Union or Persia (or both) is absent.
3. Telegrams show that there is a tendency for United Kingdom, United States and, perhaps Persia to concentrate exclusive attention upon the issue of a breach by Russia of the Tripartite Treaty.  It must also be remembered, however, that the Council was duly seized of the Persian matter before any question of breach of Treaty arose. The Treaty aspect is, of course, important and must be dealt with by the Council, but if a long-term and just solution of the Persian problem is to be reached, the Treaty question should be dealt with not in isolation but in conjunction with the question of general Soviet/Persian relationship.
4. If the Soviet representative does not attend the meeting on 3rd April the Council should be satisfied that due notice of meeting has been given to Soviet Union by Secretary General. Presumably Council would then proceed to hear report from Secretary General on result of his enquiries addressed to Soviet and Persian Governments. This report may bring out facts which may throw new light on situation and may suggest need for further questioning.
If Persian Ambassador gives supplementary report this would present further opportunity for questioning him and getting into evidence relevant reports between him and his government.
5. It would appear that United States might then move resolution requesting the Soviet to withdraw troops from Persia unconditionally. Soviet representative if present may conceivably argue there is no dispute and claim right to veto Council decision on this question.  While this attitude might be in accordance with four-Power claims at San Francisco, in our view as we stated at San Francisco  no such veto exists under the Charter.
Whether or not Soviet representative is present point will probably arise as to what countries are entitled to vote on United States resolution of kind suggested above. As you know it is our view that United States and United Kingdom are also parties to dispute , but it would not be appropriate for Australia to take lead in establishing that United Kingdom has no right to vote.
