I. JURISPRUDENTIAL BACKGROUND AND THEORETICAL ISSUES
To date, traditional international law does not consider human environmental rights to a clean and healthy environment to be a jus cogens human right. Jus cogens (“compelling law”) refers to preemptory legal principles and norms that are binding on all international States, regardless of their consent. They are non-derogable in the sense that States cannot make a reservation to a treaty or make domestic or international laws that are in conflict with any international agreement that they have ratified and thus to which they are a party. They “prevail over and invalidate international agreements and other rules of international law in conflict with them… [and are] subject to modification only by a subsequent norm… having the same character.” (1) Thus, they are the axiomatic and universally accepted legal norms that bind all nations under jus gentium (law of nations). For example, some U.N. Charter provisions and conventions against slavery or torture are considered jus cogens rules of international law that are nonderogable by parties to any international convention.
While the international legal system has evolved to embrace and even codify basic, non-derogable human rights (2), the evolution of environmental legal regimes have not advanced as far. While the former have found a place at the highest level of universally recognized legal rights, the latter have only recently and over much opposition, reached a modest level of recognition as a legally regulated activity within the economics and politics of sustainable development.

1. The international legal community recognizes the same sources of international law as does the United States’ legal system. The three sources of international law are stated and defined in the Restatement (Third) of the Foreign Relations Law of the United States (R3dFRLUS), Section 102. The first source is Customary International Law (CIL), defined as the “general and consistent practice of states followed out of a sense of legal obligation” (3) (opinio juris sive necessitatus), rather than out of moral obligation. Furthermore, CIL is violated whenever a State, “as a matter of state policy,… practices, encourages or condones (a) genocide, (b) slavery… (c) the murder or causing the disappearance of individuals, (d) torture or other cruel, inhuman or degrading treatment… or (g) a consistent pattern of gross violations of internationally recognized human rights.” (4) To what extent such human rights need to be “internationally recognized” is not clear, but surely a majority of the world’s nations must recognize such rights before a “consistent pattern of gross violations” results in a violation of CIL. CIL is analogous to “course of dealing” or “usage of trade” in the domestic commercial legal system.
