UN General Assembly
1983

76. As an international rally advocating right and justice, the Conference revealed the isolation of those States that failed to shoulder their responsibilities and confined themselves to participating in the work of the Conference as observers. That position represents a denial of the noble principles of freedom, independence and justice which their peoples were the first to uphold and advocate in the march of mankind in this epoch. 77. Separate attempts to find a partial solution to the conflict in the Middle East have been futile. Similarly, attempts to prevent the PLO, the sole legitimate representative of the Palestinian people, from participating in these efforts are also futile and unjust and are not really aimed at reaching an equitable and authentic solution to the problem.
