The Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (OPANAL) is an inter-governmental agency created by the Treaty of Tlatelolco to ensure that the obligations of the Treaty are met. Since 1998, all 33 states in Latin America and the Caribbean have been Members of OPANAL. OPANAL is responsible for convoking regular and special general conferences and consultation meetings related to the established purposes, means, and procedures of the Treaty. OPANAL also supervises the adherence to the Control System and the obligations stemming from the Treaty of Tlatelolco.
The General Conference is one of the three main bodies of OPANAL, which convenes for regular sessions biennially and for special sessions when deemed necessary. The General Conference has a number of duties: studying and ruling on any issue or matter addressed in the Treaty of Tlatelolco, including those that refer to the powers and functions of OPANAL’s administrative bodies; establishing procedures to ensure the adherence to the Control System established by the treaty; electing the members of the council; electing and dismissing the secretary-general; receiving and reviewing biennial and special reports presented by the council and the secretary-general; establishing agreements with governments and international agencies; approving the agency’s budget and establishing the financial contributions scale for Member States; electing the authorities for each session of the General Conference; establishing any subsidiary organization deemed necessary; and approving the Rules of Procedure.
The council consists of five members who meet regularly every two months and in special meetings as is necessary. The members are elected for a term of four years. The governments of, Brazil, Guatemala, Mexico, Paraguay and Peru currently comprise the Council.
The Secretariat consists of the secretary-general, who is the chief administrative officer of the agency, and the staff. The secretary-general is appointed for four years and may be re-elected to serve a single additional term. The secretary-general may not be a national of the host country (Mexico). Ambassador Luiz Filipe de Macedo Soares (Brazil) will hold the position of Secretary-General for the period from 1 January 2014 to 31 December 2021.
Verification and Compliance
On 26 August 1992, during its eighth extraordinary session, OPANAL's General Conference approved amendments to Articles 14, 15, 16, 19, and 20 relating to the verification and control system established by the Tlatelolco Treaty. The purpose of these amendments was to strengthen the verification system while recognizing the International Atomic Energy Agency (IAEA) as the only organization capable of carrying out special inspections requested by parties to the Treaty. The 1992 General Conference at the same time upheld the principle that the organs of OPANAL would continue to be responsible for monitoring the application of the treaty's control system. It should be emphasized that, although the approved amendments modify the verification system, none of the modifications alters the fundamental principles or the essence of the Tlatelolco Treaty.
If a party were found to be in non-compliance, the IAEA would refer the case to the United Nations Security Council.
