A/HRC/33/43 Additionally, few States make even limited references to the involvement of law enforcement agents in the activities of private military and security companies and very few references were found to specific rules on the export of weapons and firearms by company personnel. The use of force is regulated in detail by only one of the countries reviewed. 95. The Working Group notes that while some of the reviewed countries have demonstrated commitment to the international legal instruments related to mercenaries, the research reveals very limited reference to international standards in their domestic laws. The Working Group calls on those countries that are parties to the international instruments on mercenaries to incorporate the international standards into national legislation and to introduce relevant enforcement and accountability mechanisms. The Working Group also encourages signatory countries to ratify, and the remaining States to become parties, to the relevant instruments. 96. The Working Group reiterates its view that a comprehensive, legally binding international regulatory instrument is the best way to ensure consistent regulation worldwide and adequate protection of the human rights of all affected by the activities of private military and security companies. An international convention would provide a standard regulatory framework for various essential issues related to the activities of private military and security companies and a single dedicated body would ensure the accountability of these companies’ personnel in guaranteeing the right to effective remedies of all victims worldwide. 97. The Working Group also encourages Governments in the various regions it has reviewed to promote discussion on the role of private security companies in the context of regional security, as part of the agendas of intergovernmental, regional and subregional organizations. 22
