Response to Blum Published
As readers will recall, I wrote a short response to Gabriella Blum’s wonderful essay on IHL and common-but-differentiated responsibilities for our inaugural Opinio Juris–Harvard International Law Journal symposium. HILJ has now published my much longer formal response. Here is an overview, from my introduction:
Blum’s normative analysis of the desirability of CDRs in IHL is exceptionally powerful, and I agree with most of her conclusions. This brief response, therefore, is intended to be more constructive than critical. In particular, I want to raise five issues that I believe warrant further exploration: (1) whether permitting judges to differentially apply IHL standards could be seen as legitimate; (2) whether proportionality is the kind of standard that permits differential application; (3) whether, and to what extent, CDRs would encourage states and nonstate actors to comply with IHL; (4) whether the case for CDRs might be stronger in non-international armed conflict (NIAC) than in international armed conflict (IAC); and (5) whether it is possible to assess the humanitarian effect of CDRs without abandoning the jus ad bellum/jus in bello distinction. I conclude that, in fact, Blum’s own analysis supports recognizing at least one kind of CDR: namely, requiring strong states to spend more money than weak states on procuring and using precision weaponry.
