The ICRC has published a report on customary international law in the realm of international humanitarian law. I will resist the nearly irresistible urge to opine on both my thoughts on the ICRC (positive and negative) and the some very objectionable points in its report. I do promise everyone that much ink will be spilt parsing the language of this report in the endless (and fruitless?) search for viable CIL.
Tip to Opinio Juris for the heads up.
