This practical guide aims to assist States as they move towards becoming parties to the Convention for the Protection of all Persons against Enforced Disappearance, and to promote the universal ratification of this key Convention. It provides answers to questions commonly raised by States when considering this commitment, and a toolkit to encourage and support States in joining the community of parties committed to prevent and eradicate enforced disappearances and fight against the impunity of this heinous crime. The publication complements OHCHR’s Manual on Reporting Under the International Convention for the Protection of All Persons from Enforced Disappearance (which includes a Training Guide and accompanying training modules).
