This week on Opinio Juris, Roger commented on Joel Trachtman's article on customary international law, which attracted a lot of debate from our readers in the comments. Kevin lamented US Courts' insufficient understanding of IHL and wondered if Paddington would prefer Australia's Christmas Island. He also responded to Ryan Vogel's post on Lawfare on the OTP's Afghanistan's investigation. Julian explained why he does not fully agree with...

As a number of commentators have recently noted, the latest report on the OTP's preliminary-examination activities indicates that the OTP is specifically considering whether US forces are responsible for war crimes relating to detainee treatment in Afghanistan -- something it only hinted at in its 2013 report. Here are the relevant statements (pp. 22-23): 94. The Office has been assessing available information relating to...

I'm sure most of us will go see the live-action movie version of PADDINGTON, which recently hit the big screen. And we will do so, of course, because we are interested in what Paddington's residence status says about the UK's harsh immigration laws. Fortunately, Colin Yeo has prepared a nice primer for us at the Free Movement blog, run by...

That's the provocative conclusion of the latest research by Joel Trachtman. Trachtman's articles are typically succinct and seductive, so you owe it to yourself to read the short article (and skim the long appendix). Trachtman examined 300 different CIL rules and found that only 13 (4.33%) have not been either incorporated in treaties or codified. Trachtman argues that the...

This Thanksgiving week saw several posts of note on Opinio Juris. We hosted a Mini-Symposium on the latest article by James G. Stewart, The Turn to Corporate Criminal Liability for International Crimes: Transcending the Alien Tort Statute. First, Samuel Moyn discussed the ambitious past of corporate regulation, to which Stewart responded in hopes that the ideas set forth by both would...
