A Hypothetical About the Beginning of IAC

A number of us -- me, Aurel Sari, Eliav Lieblich, Andrew Bell, Sasha Greenawalt, Craig Martin, Ed Swaine -- have been having an interesting discussion on Twitter about two important issues concerning the use of force. The first is when IHL begins to apply in an IAC. The traditional position is that any use of interstate force triggers IHL and...

A few days ago, I had the pleasure of giving an online lecture for the Iranian Center for International Criminal Law about the relationship between the US and the ICC. In the lecture, I trace the evolution of the US-ICC relationship and try to predict what that relationship will look like under President Biden. I also speculate about why Trump has...

What does the dean of a law faculty do? I asked myself this question throughout my academic career. Most of the time, they appear both indispensable and irrelevant in equal measure. Deans are quixotic, sometimes even hostile. They do not teach; they produce little research; and many law faculties are acrimonious places, suggesting that organisational leadership is not within their...

I just had the pleasure of a sharp exchange on Twitter with my dear friend Mark Kersten, one of the most insightful commentators on the ICC.

Judge Barrett is set to become Justice Barrett. Throughout her nomination process, I have been quite fascinated by the discussion surrounding her originalist views and originalism in general. As someone not used to originalism as a theory of Constitutional interpretation (it has not really caught on in Peru), this added exposure has offered me some new perspectives I had not previously considered, including originalism’s identity...

[Chris Jenks is the Director of the Criminal Clinic and Associate Professor of Law at SMU Deadman School of Law.] How is ‘attack’ defined under international humanitarian law (IHL), particularly in the context of cultural property and hospitals? Opinio Juris readers will likely have already answered the first part of the question by referring to Article 49 of Additional Protocol I (AP I) to the 1949...
