While this blog is having some down time over the summer, I thought I would provide a link to a short but interesting article: "Improving Inter-State Cooperation for the National Prosecution of International Crimes: Towards a New Treaty?" is part of the American Society of International Law's series of online articles (called "ASIL Insights"). This one is by Ward Ferdinandusse, a Dutch prosecutor who teaches International Criminal Law at the University of Groningen.
There is apparently an extant proposal to draft a multilateral convention to strengthen the overall extradition/mutual legal assistance machinery for the core crimes. I was not aware of the proposal, and I'm grateful to Mr. Ferdinandusse for bringing it to more general knowledge via this article.
The article is available here. Recommended reading!
