Professor Lindsay Nash published a short essay in the Journal on Migration and Human Security (JMHS), a publication of the Center for Migration Studies.
Professor Gabor Rona presented at the UN in Geneva, in his role as Chairperson-Rapporteur of the Working Group on the use of mercenaries as a means of violating human rights and impeding the exercise of the right of peoples to self-determination. His report focused on the Working Group's now completed four year-long global study of national legislation regulating the private military and security industry. The study found significant legal gaps in accountability of private military and security operators for violations of human rights and and in the availability of enforceable remedies for victims.
The working group is mandated by the UN Human Rights Council to study and report on, among other things, the effects of mercenarism, mercenary-related activities (such as 'foreign fighters') and private military and security contract operations on the enjoyment of human rights, in particular, the right of peoples to self-determination.
