Customary (And Not So Customary) International Environmental Law

In this article, Professor Bodansky examines the creation and importance of customary international law. He suggests that the debate over the legal status of any given norm may be misplaced Instead, he suggests that international lawmakers should spend their time and energy incorporating norms, regardless of their true status, into concrete treaties and actions. The author begins his discussion by providing a working definition of customary international law. He asserts that such law can be based not just on uniformities of state behavior, as is traditionally held, but also on regularities in behavior. Thus, customary international law can be formed even when states do not fully comply with a particular norm. Next, Professor Bodansky contends that state declarations may be just as indicative and useful in uncovering customary international law as state behavior. But the author goes on to state that such declarative law does not and should not carry the same weight as customary norms based on state behavior. Because such norms are nonlegal, courts and other arbiters cannot enforce them against a state. The author concludes, however, that these non-legal norms may play a significant role in setting the terms of the debate, especially in negotiations between states. These norms can then be incorporated into treaties and other internationala greements, making them more concrete and enforceable. Ultimately, as the author states, the international community should spend less time debating a norm\u27s legals tatus and more time translatingg eneral norms into enforceable treaties
