Revision of Customary international law is no longer sufficient to protect U.S. interests from Sat, 06/28/2014 - 14:18
Opponents of UNCLOS claim that the United States should not become a party because the United States already enjoys the benefits of UNCLOS through customary law and, therefore, should not unnecessarily incur the treaty's burdens. However, this ignores the fact that customary law can change and can also be influenced by how parties to UNCLOS decide to interpret its provisions.

Each year the United States challenges dozens of states for asserting legal rights that impede freedom of the seas. Iran, North Korea, and China have all challenged the U.S. navy’s free passage through their EEZ. By codifying the right to pass freely through the exclusive economic zone of foreign states without restrictions on cargo or formation, the Law of the Sea strengthens America’s ability to project power.
But these rights are already recognized as customary international law. What does the Convention add? For one, it makes these rights stronger. Written treaties are perceived as more powerful than customary laws. By signing the Convention, the United States gives added weight and stability to customary rights, and pushes recalcitrant states to respect navigational freedoms.
More importantly, the Convention creates a forum to change navigational rights. It is possible, though unlikely, that future deliberations under the Convention might create rules that undermine freedom of navigation. If the United States fails to ratify the Convention, it will lose the opportunity to defend these rights. The problem is not that other states can stop the U.S. Navy from sailing where they want to sail. The problem is that they can raise the costs of doing so. If a nation decides to forbid U.S. ships their legal right to pass, America could use force to assert our right. But, realistically, it will be more likely to seek legal remedy. Signing the Convention lowers the cost of projecting power.

UNCLOS opponents are correct on at least one point. The customary international law of the sea – at least as generally understood today – is consistent with U.S. national security interests. The U.S. government has said as much.15 However, in relying on the apparent harmony between UNCLOS and customary law as rationale for the U.S. to remain outside the treaty, opponents have failed to address a critical question: What if UNCLOS or customary law changes? Is it possible that today’s favorable legal environment could evolve adversely to U.S. interests?
The question is more than speculative. Through the years, a variety of nations have advanced legal theories inconsistent with critical U.S. ocean policy interests.16 Historically, these nations have lacked the will or ability to affect meaningful change in the international law of the sea. Today, however, this dynamic is changing.
Consider, for example, U.S. military operations in the off-shore area known as the EEZ, as codified by UNCLOS, comprising the waters beyond a nation’s territorial sea extending a maximum of 200 nautical miles from the coast.17 For years, the U.S. has consistently maintained the right under customary international law to conduct military activities in coastal state EEZs.18 Over the past decade, however, the People’s Republic of China has initiated confrontations with U.S. ships and aircraft operating in the Chinese-claimed EEZ and its associated airspace. The Chinese have boldly rejected long-standing U.S. positions on customary international law and also challenged conventional interpretations of critical UNCLOS provisions.

Putting aside for now the potential consequences of blurring the distinction between broadly ratified convention regimes and customary law for other subject areas of concern (e.g., the 1977 Additional Protocols to the Geneva Conventions and the Rome Statute for the ICC), one might reasonably ask what response such a position might invite from other states that are now parties to the LOSC. Could they too circumvent the LOSC’s ban on reservations and avoid its compulsory dispute settlement provisions by renouncing the LOSC in favor of customary law? Even if empirically sound, the argument that nothing is to be gained by the United States in ratifying the LOSC, because all of the best parts either codified existing customary law when the Convention was opened for signature or later (i.e., between 1982 and 1994, when it entered into force) ripened into customary law, must be tested against the fallacy of composition. If that is true for the U.S., wouldn’t it also be true for the 160+ nations that are already parties to the LOSC? In short, do regimes founded on rules of customary law better serve the national and shared interests than those founded on treaties?
The common understanding of the fallacy of composition is that what might be true for the one is not necessarily true for the many. If one person in a crowd stands on tiptoes to see better he might be better off, but if everyone does it no one is better off. The economist John Maynard Keynes referred to the analogous “paradox of thrift,” by which he meant that if one person saves a substantial portion of her earnings she may be better off, but if everyone saved as much it could lead to a recession.

The Convention reduces, but doesn’t wholly eliminate, the indeterminacy inherent in customary law. The Convention also provides greater stability and predictability. Here it should be noted that the LOS Convention’s articles can only be amended through an elaborate process that, by design, provides the kind of stability the U.S. has long sought in the maritime domain. By contrast, customary law rules evolve by the practice of nations asserting, acceding to or persistently objecting to new norms, thus introducing unwelcome uncertainty into the nation’s maritime affairs. Moreover, as Edwin Williamson, President George H.W. Bush’s State Department Legal Advisor noted, the history of customary international law “reflects a steady deterioration of the freedom of the seas to the detriment of the essential rights of maritime nations, such as the U.S.”
