Editing International Law Commission (section)

== Annual sessions of the commission ==
The commission's main function since its establishment has been its annual sessions, starting from 1949. At first, the proceedings of these sessions were kept in a mimeographed form and were not available to the public, but on December 3, 1955, the General Assembly passed resolution 987, which required the publication of a summary of the proceedings of these meetings in a special yearbook designated for this purpose, and this in order to make the information available to both public and governments. For the 1st session, proceedings have been published in one volume, but starting from the 2nd session, proceedings have been published in two volumes – the first containing a summary of the deliberations and the second containing documents adopted at that session.

At the beginning of each session, the commission elects one of its members to serve as its chairman until the next session.

=== 1940s sessions ===
;* 1st session, 1949
The '''1st session''' was held in Lake Success, New York from April 12 to June 9, 1949.<ref>{{Cite web|url=https://legal.un.org/ilc/sessions/1/|title=International Law Commission|website=legal.un.org}}</ref> The agenda for the first session was prepared by the General Assembly throughout 1947–1948. In resolution 177 (November 21, 1947), the Assembly charged the commission with formulating principles based on the judgement of the [[Nuremberg Tribunal]] and drafting a new code of offences against the peace of mankind. Resolution 178 (of the same day) charged the commission with preparing a document on the rights and duties of states in international law. Resolution 260 (December 9, 1948) instructed the commission to consider the establishment of a criminal chamber within the [[International Court of Justice]], for prosecuting political leaders guilty of crimes against international law.

The election of the 15 commission members by the General Assembly took place on November 3, 1948.

The first session of the commission was held in [[Lake Success, New York]], United States, from April 12 to June 9, 1949. The agenda for the session consisted of six items:
* Making a general survey of topics of international law that require codification into treaties and conventions.
* The rights and duties of states.
* The [[Nuremberg Principles]] and the definition of crimes against the peace of mankind.
* Possibility of establishing a judicial body to prosecute leaders guilty of genocide. 
* Finding ways to make the rules and documents of international law more available to the public and scholars. 
* Cooperation by the ILC with other UN agencies.

At the very first meeting, US commission member [[Manley Ottmer Hudson|Manley O. Hudson]] was elected chairman of the commission for the duration of that session, while the Soviet member [[Vladimir Koretsky]] was elected first vice-chairman and Indian member [[Benegal Rama Rau|Benegal Rau]] was elected second vice-chairman.

During that session, disagreement arose between the members as to whether the commission was entitled to include a topic on its agenda without prior consent of the General Assembly. On this issue, the commission decided that it was competent to do so, by a vote of 10 to 3.<ref>''Yearbook of the ILC, 1949'', p. 32</ref>

Regarding the range of issues to be included in the agenda for the codification of international law, the commission decided to start working on a limited number of subjects at first. For that reason, it was decided to exclude at the time the issue of [[laws of war]] from the commission's discussions. The highest priority was given to the topics of [[law of treaties]], [[arbitration]], and regime of the sea, and rapporteurs were elected accordingly.

Another topic under discussion was the declaration of the rights and duties of states. It was decided to exclude the issue of [[right of asylum]] from the proposed draft, and to discuss the matter further at the 2nd session.

Other issues postponed until the 2nd session were: 
* The formulation of the Nuremberg Principles and the list of offences against the peace of mankind.
* The issue of universal criminal jurisdiction.
* Making texts of international law more available. 
* Cooperation with governments and UN agencies.

The commission approved a '''Draft Declaration on the Rights and Duties of States''', which was the main legal document adopted at that session.<ref>[http://legal.un.org/ilc/texts/instruments/english/draft%20articles/2_1_1949.pdf "Draft Declaration on Rights and Duties of States"], 1949. International Law Commission.</ref> A large portion of the work on this issue was done by the Panamanian representative [[Ricardo Joaquín Alfaro Jované]]. The draft declaration was referred to the General Assembly for further deliberations, but in its resolution 596 of December 7, 1951, the Assembly decided to postpone any further discussions on the document.

The commission also decided about the time and place of the 2nd session to be held. It was decided to hold it in Geneva, starting from May 1950, for a maximum period of 10 weeks.

=== 1950s sessions ===
;* 2nd session, 1950
The '''2nd session''' was held in [[Geneva]] from June 5 to July 29, 1950.<ref>{{Cite web|url=https://legal.un.org/ilc/sessions/2/|title=International Law Commission|website=legal.un.org}}</ref> The chairman of that session was [[Georges Scelle]]. The agenda and the final resolutions of the session were as follows:
* '''Original item''': Report of the 1st session and the draft declaration on the rights and duties of states, both of which were now approved by the General Assembly. '''Decision''': the commission took note of that without taking further action.

'''Decision''': the commission formulated a set of seven principles to be referred to as "Nuremberg Principles", dealing with responsibility of states and individuals in cases of crimes against humanity being committed. 
* '''Original item''': The desirability and possibility of establishing an international court to try political leaders guilty of genocide. '''Decision''': the commission passed resolutions to the effect that the creation of such a court was desirable and possible. However, the creation of such a court was postponed until further discussions. 
* '''Original item''': Law of treaties. '''Decision''': the commission postponed decisions until further study.

* '''Original item''': Ways of making texts of international law more available. '''Decision''': the commission recommended that wide distribution be made of UN publications on international law and that the UN begin publications of documentary series on international tribunals and national laws and constitutions of various states. In addition, the commission recommended to the General Assembly to formulate an international convention to regulate the exchange of legal publications between governments.
* '''Original item''': Right of asylum. '''Decision''': the commission decided to postpone any deliberations on the subject, since the issue was under discussion by the International Court of Justice. 
* '''Original item''': Cooperation of the commission with other UN agencies, governments and other national and international organizations.
* '''Original item''': Date and place of the 3rd session. '''Decision''': the commission decided it should be held in Geneva for a maximum period of 12 weeks starting from May 1951.

The conduct of the 2nd session was influenced by the East-West rift resulting from the [[Cold War]]. Already at the first meeting of that session, the Soviet member Koretsky protested that the [[People's Republic of China]] (PRC) was not represented on the commission, claiming it represented the Chinese people and not the [[Republic of China]] (ROC), now ruling in [[Taiwan]] only. He demanded the Chinese member of the commission be replaced by a member from mainland China. Commission chairman Scelle opposed the Soviet demand, claiming that each member represented his own legal views rather than any government position. The commission accepted Hudson's position by the vote of 10 to 1, and Koretsky in protest left the session without attending any further meetings.<ref>''Yearbook of the ILC, 1950'', vol. 1, pp. 1–2</ref> A letter of protest by the PRC government against the representation of the ROC at the commission was presented to the commission on June 8, but no further action was taken in that regard.

;* 3rd session, 1951
The '''3rd session''' was held in Geneva from May 16 to July 27, 1951. The agenda of the session was as follows:

The conduct of the session was influenced by other international events, as the Syrian representative [[Faris El-Khouri]] was absent from the early meetings due to UN deliberations of Syrian complaints against [[Israel]].
