Having quite a few engagements with UN offices and officials on this issue,
I thought it may be useful to write a summary version of what I found in my research in relation to legal obstacles to prosecution for crimes, in fact sexual or otherwise, committed by UN Peace Operations personnel.
It looks into criminal jurisdiction and immunity, which are often believed to be standing in the way of willing States to prosecute. My research revealed that it is not the case. The vast majority of crimes committed in UN Peace Operations can be prosecuted if the law is applied correctly.
Here is the link to the article published on our University of Tokyo’s International Law Training and Research Hub website. It is a summary version, and if you wish to see the whole analysis to get to this conclusion, my book has a more thorough analysis on the same.
