The United Nations Inter-regional Crime and Justice Research Institute (UNICRI) based in Rome requested support from 9 BRi and David Hammond for the drafting and development of the new Rome document for employment of Private Maritime Security Companies (PMSC) and engagement of Privately Contracted Armed Security Personnel (PCASP). This has seen the inclusion of the 100 Series Rules for the Use of Force as one of the draft Articles.
The informal expert working group met in Rome on 26th March 2013 and was comprised of 12 maritime experts from the UNICRI, IMO, BIMCO, the Italian Government, military and academia and the United Nations Division for Ocean Affairs and the Law of the Sea (DOALOS).
