Adopted by the Security Council at its 222nd meeting, on 9 December 1947 
The Security Council,
Decides to include in its rules of procedure the following revised rules:
Chapter X - Admission of New Members
Any State which desires to become a member of the United Nations shall submit an application to the Secretary-General. This application shall contain a declaration made in a formal instrument that it accepts the obligations contained in the Charter.
The Security Council shall decide whether in its judgement the applicant is a peace-loving state and is able and willing to carry out the obligations contained in the Charter, and accordingly whether to recommend the applicant State for membership.
If the Security Council recommends the applicant State for membership, it shall forward to the General Assembly the recommendation with a complete record of the discussion.
If the Security Council does not recommend the applicant State for membership or postpones the consideration of its application, it shall submit a special report to the General Assembly with a complete record of the discussion.
In order to ensure the consideration of its recommendation at the next session of the General Assembly following the receipt of the application, the Security Council shall make its recommendation not less than twenty-five days in advance of a regular session of the General Assembly, nor less than four days in advance of a special session.
In special circumstances, the Security Council may decide to make a recommendation to the General Assembly concerning an application for membership subsequent to the expiration of the time limits set forth in the preceding paragraph.
 Adopted without vote.
