The Ibero-American Convention on Young People's Rights, which entered into force on 1 March 2008, explicitly recognises the right to conscientious objection. Article 12 of the Convention reads: "Young people have the right to form a conscientious objection against compulsory military service." It also includes a commitment of states to create legal instruments to safeguard this right, and to progressively end compulsory military service. However, presently only Ecuador, the Dominican Republic, Honduras, Spain, and Costa Rica ratified this convention, which also lacks any monitoring mechanism, although ratifying states are required to submit a report every two years.
