Article 1

A permanent organisation is hereby established for the promotion of the objects set forth in the Preamble to this Constitution and in the Declaration concerning the aims and purposes of the International Labour Organisation adopted at Philadelphia on 10 May 1944 the text of which is annexed to this Constitution.

The Members of the International Labour Organisation shall be the States which were Members of the Organisation on 1 November 1945, and such other States as may become Members in pursuance of the provisions of paragraphs 3 and 4 of this article.

Any original Member of the United Nations and any State admitted to membership of the United Nations by a decision of the General Assembly in accordance with the provisions of the Charter may become a Member of the International Labour Organisation by communicating to the Director-General of the International Labour Office its formal acceptance of the obligations of the Constitution of the International Labour Organisation.

The General Conference of the International Labour Organisation may also admit Members to the Organisation by a vote concurred in by two-thirds of the delegates attending the session, including two-thirds of the Government delegates present and voting. Such admission shall take effect on the communication to the Director-General of the International Labour Office by the government of the new Member of its formal acceptance of the obligations of the Constitution of the Organisation.

No Member of the Internationl[lees: International] Labour Organisation may withdraw from the Organisation without giving notice of its intention so to do to the Director-General of the International Labour Office. Such notice shall take effect two years after the date of its reception by the Director-General, subject to the Member having at that time fulfilled all financial obligations arising out of its membership. When a Member has ratified any international labour Convention, such withdrawal shall not affect the continued validity for the period provided for in the Convention of all obligations arising thereunder or relating thereto.

In the event of any State having ceased to be a Member of the Organisation, its readmission to membership shall be governed by the provisions of paragraph 3 or paragraph 4 of this article as the case may be.
