Is International Criminal Law 'Crowding Out' the Rest of International Law?

That's the question underlying my new essay, The Rise of International Criminal Law: Intended and Unintended Consequences, in the European Journal of International Law (Vol. 20, No. 2, June 2009). And I'm curious as to whether anyone else shares my general feeling that the very success (on some metrics, anyway) of international criminal law is tending to swallow, as it were, the rest of public international law.
