John Bellinger, the head of the Office of the Legal Adviser at the State Department, will be guest-blogging at Opinio Juris the week of January 15th (Monday to Friday). To the best of our knowledge, this will be the first time that anyone at the State Department — particularly someone in such a critical position — will have blogged in their official capacity.
Should be interesting! The OJ crowd have also invited some academic guests to participate in the conversation.
