...on are all military offenses that have no analogous "crime" in either domestic or international law. There is no actual charge of spying. The offense in Quirin was "passing through lines of defense without uniform". This has nothing to do with spying, or the civilian crime of espionage. It also has a special rule, because if the enemy solider passes back through your lines and rejoins his army then the offense is cancelled out and he can never be charged with it. There is no comparable "home free" rule that...

...with sophisticated surveillance gear but also missiles, act as the lightest of light cavalry. They probe, surveil, and engage in pinprick attacks, behind enemy lines, far beyond one’s own lines. When the CIA engages in targeted killing against some Al Qaeda operative in Somalia, from a strategic perspective, it is a combat raiding strategy by very light cavalry indeed. But it is so far beyond one’s own lines, as it were, that from a legal standpoint, I would place it beyond the legal “armed conflict” altogether and treat this combat...

[David Matyas is a PhD Candidate and Gates Cambridge Scholar at the University of Cambridge, Lauterpacht Centre for International Law whose research focuses on the laws of humanitarian assistance. Before turning to law, he worked as an aid worker focusing on disaster risk, with placements in Niger and Senegal.] Each year, as the holidays roll around in winter and summer, I’m reminded of a few lines by US Supreme Court Associate Justice Louis D. Brandeis to a young lawyer at his firm. He writes, “The bow must be strung and...

...the legitimacy of the judiciary, since “bright lines” can often appear to favor systematically one value or one constituency over another in an area of normative contestation (the authors discuss the now clearly rejected (Shrimp/Turtle) “bright line” that the unadopted Tuna/Dolphin panels invented on PPMs, which systematically excluded a whole range of activist environmental strategies from consistency with WTO law): here we should consider Cass Sunstein’s thinking about “one case at a time.” Where the AB has strayed from this strategy and tried to draw brighter lines, it has usually...

...that questions about self-defense are even being raised at this point is because practice has far outpaced the law. Thus, to complement the other contributors’ outlines of state positions, I am going to focus on the state of practice surrounding self-defense. For this I will rely on a series of studies I conducted examining how individual and unit self-defense have been used by different NATO countries in Afghanistan, Iraq, and in other undeclared conflict zones. In addition to background legal research, I interviewed some 78 military lawyers, commanders, and other...

...public quality to practical knowledge as we use it to progress defined social purposes: information transmission, problem-solving, career progression, innovation, and future-building figure high in our priorities. It also possesses a private character as we employ it to improve professional practice and industrial activities in service of individual and corporate interests. Despite the purported division between universities and the real world, researchers produce knowledge destined for assembly lines and boardrooms as well. Most influential of all the forms is knowledge as identity. The knowledge we internalise is intimate, comparable to...

...rendition of figure 3. It illustrates the extent to which meaning produced in testimony can be altered through ignoring its wider interactional context: Once the Judge obtains the answer that later reappears as part of ‘the pattern’ (lines 12-14), he returns the floor to the defence counsel. The latter in turn invites the witness to recontextualize his previous answers, by asking two targeted questions about the time frame of his belief (lines 17-18 and 20-21). In the answer (only partially reproduced here), the witness responds with a biographical account that...

...extensive lines of code involved, rendering it challenging for enforcement agencies to assess. Unlike conventional technologies where physical characteristics can be examined, AI systems often consist of intricate algorithms with millions of lines of code, making it daunting to verify their functionalities, especially when those functionalities could have both benign and harmful applications.  In addition to the monitoring and verification challenges, AI is increasingly provided as a service rather than a standalone product, complicating export controls and oversight of its use across multiple countries. With the rise of cloud computing...

...give one example, the normative idea of transnational legal process would suggest that the travel ban should have been litigated as an international human rights issue. In practice, however, the litigation had to be rooted in the Establishment Clause and administrative law arguments to prevail in the lower courts (and even these arguments, dismayingly, did not win a majority of the Supreme Court). Professor Koh gives a good description of this litigation, but he does not address the tension between his transnational legal process frame and the lines on which...

[ Sarah Shoker is a Senior Non-Resident Fellow in artificial intelligence at U.C. Berkeley Risk and Security Lab and former Geopolitics Team Lead at OpenAI. Jessica Dorsey is an Assistant Professor of International Law at Utrecht University School of Law and Managing Editor of Opinio Juris.] What began as a quiet contract dispute between the U.S. Department of Defense and the AI firm Anthropic in February 2026 has become a high-stakes confrontation over the invisible lines companies draw around AI in warfare. Central to this is deciding who determines the...

...mechanisms (possibly including new rules for the CDM and for land-use change), and capacity-building. Given the current state of the negotiations (which remain bogged down), an outcome along these lines remains a very ambitious objective for Copenhagen, even if it is reflected “only” in COP decisions rather than in a new legal agreement. How much does the legal status of the Copenhagen outcome matter? For years, academics have been debating the merits of “soft” vs. “hard” law. Now, this issue has moved front and center in the climate negotiations. Coming...
