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 Eric Posner’s view on international human rights law clinics and asked whether the Supreme Court implicitly reversed Kiobel’s corporate liability holding.

Finally, Jessica wrapped up the international news headlines and listed events and announcements.

Have a nice weekend!
