The nineteenth (1964–1965) session of the General Assembly was virtually deadlocked over the financial crisis, a crisis which arose as a result of disagreement between the Members about how the United Nations peacekeeping operations were to be financed. Three years earlier, in 1961, the General Assembly, having been informed of the substantial arrears in the payment of assessments, mainly for the United Nations Emergency Force (UNEF) and the United Nations Operation in the Congo (ONUC), adopted on December 20, a resolution asking the International Court of Justice to give an advisory opinion as to whether the expenditures authorized for the UNEF and ONUC operations constituted “expenses of the Organization” within the meaning of Article 17, paragraph 2, of the United Nations Charter. On December 19, 1962, the Assembly voted to accept the advisory opinion of the Court to the effect that the expenditures of these operations constituted “expenses of the Organization” within the meaning of Article 17 (2) of the Charter. However, attempts to extract the arrears from the defaulting states, the largest of which were the Union of Soviet Socialist Republics (Soviet Union) and France, on the strength of the Court's advisory opinion, largely failed; and the matter came to a head at the nineteenth session of the General Assembly when some Members, notably the United States, proposed that sanctions under Article 19 of the Charter be taken against the defaulting states. The crisis was finally averted toward the end of the nineteenth session when the United States decided not to pursue the question of sanctions.
