International Law Commission

Last update: September 22, 2022

Texts, Instruments and Final Reports

Under article 20 of its Statute, the Commission is required to prepare drafts in the form of articles and to submit them to the General Assembly together with a commentary containing an adequate presentation of precedents and other relevant data, including treaties, judicial decisions and doctrine; as well as conclusions defining the extent of agreement on each point in the practice of States and in doctrine, and divergencies and disagreements which exist, as well as arguments invoked in favour of one or another solution.

Upon receiving comments from Governments on its draft articles, the Commission prepares a final draft and explanatory report, which it submits with its recommendations to the General Assembly (article 22 of its Statute). The Commission may recommend to the General Assembly: (a) to take no action, the report having already been published; (b) to take note of or adopt the report by resolution; (c) to recommend the draft to Members with a view to the conclusion of a convention; or (d) to convoke a conference to conclude a convention (article 23, paragraph 1).

Since its establishment, the International Law Commission has prepared and submitted a number of final reports, in some cases, together with draft texts, some of which (as indicated) were adopted as international conventions or other instruments.

Select the respective topic from the following list, organized according to the outline adopted in the Report on the Long-Term Programme of Work in 1996 (reproduced in Annex II of the Report of the International Law Commission, A/51/10). Instruments concluded under the auspices of the United Nations on the basis of prior drafts prepared by the Commission are indicated in italics.
