History of the Treaty
The Conference on Disarmament (CD) began its substantive negotiations on a comprehensive nuclear-test-ban treaty in January 1994 within the framework of an Ad Hoc Committee established for that purpose. Although the CD had long been involved with the issue of a test-ban, only in 1982 did it establish a subsidiary body on the item. Disagreement over a mandate for that body blocked tangible progress for years.
After more than two years of intensive negotiations, the Chairman of the Ad Hoc Committee, Ambassador Jaap Ramaker of the Netherlands, presented a final draft treaty to the CD in June 1996. An overwhelming majority of Member States of the CD expressed their readiness to support the draft treaty. India, for its part, stated that it could not go along with a consensus on the draft text and its transmittal to the United Nations General Assembly. The main reasons for such a decision, as India pointed out, were related to its strong misgivings about the provision for the entry-into-force of the treaty, which it considered unprecedented in multilateral practice and running contrary to customary international law, and the failure of the treaty to include a commitment by the nuclear-weapon States to eliminate nuclear weapons within a time-bound framework.
As a result, Australia, on 22 August 1996, requested that the General Assembly resume the consideration of agenda item 65, entitled “Comprehensive Nuclear Test-Ban Treaty” as provided for in resolution 50/65 of 12 December 1995. For that purpose it also submitted the draft CTBT, identical to that negotiated in the CD, for adoption by the General Assembly. On 10 September, the General Assembly by resolution (A/RES/50/245) adopted the Comprehensive Nuclear Test-Ban Treaty and requested the Secretary-General of the United Nations, in his capacity as Depositary of the Treaty, to open it for signature at the earliest possible date. The Treaty was opened for signature in September 1996.
Article XIV of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) states that if the Treaty has not entered into force three years after the date of the anniversary of its opening for signature, a conference may be held upon the request of a majority of ratifying States. Such a conference is held to examine to what extent the requirements for entry into force have been met, and to decide on measures to accelerate the ratification process. Previous Conferences on Facilitating the Entry into Force of the Treaty were held in 1999, 2003 and 2007 in Vienna, and 2001, 2005 2009 and 2011 in New York.
Pursuant to Article XIV, and at the request by a majority of States which have already deposited their instruments of ratification of the Treaty, the Secretary-General of the United Nations, in his capacity as the Depositary of the Treaty, will convene the eighth Conference on Facilitating the Entry into Force of the CTBT on 27 September 2013 in New York.
