<P> Although the resolutions passed by the General Assembly do not have the binding forces over the member nations (apart from budgetary measures), pursuant to its Uniting for Peace resolution of November 1950 (resolution 377 (V)), the Assembly may also take action if the Security Council fails to act, owing to the negative vote of a permanent member, in a case where there appears to be a threat to the peace, breach of the peace or act of aggression . The Assembly can consider the matter immediately with a view to making recommendations to Members for collective measures to maintain or restore international peace and security . </P> <P> The first session of the UN General Assembly was convened on 10 January 1946 in the Methodist Central Hall in London and included representatives of 51 nations .
