Artikel 13

1. The Subcommittee on Prevention shall establish, at first by lot, a programme of regular visits to the States Parties in order to fulfil its mandate as established in article 11.
2. After consultations, the Subcommittee on Prevention shall notify the States Parties of its programme in order that they may, without delay, make the necessary practical arrangements for the visits to be conducted.
3. The visits shall be conducted by at least two members of the Subcommittee on Prevention. These members may be accompanied, if needed, by experts of demonstrated professional experience and knowledge in the fields covered by the present Protocol who shall be selected from a roster of experts prepared on the basis of proposals made by the States Parties, the Office of the United Nations High Commissioner for Human Rights and the United Nations Centre for International Crime Prevention. In preparing the roster, the States Parties concerned shall propose no more than five national experts. The State Party concerned may oppose the inclusion of a specific expert in the visit, whereupon the Subcommittee on Prevention shall propose another expert.
4. If the Subcommittee on Prevention considers it appropriate, it may propose a short follow-up visit after a regular visit.
