Law of the Sea

For a quarter-century, a consensus has prevailed that territorial sovereignty applies online as it does offline. Since practically all the Internet’s infrastructure and its billions of users reside on the territory of states, conventional wisdom holds that sovereignty must extend to cyberspace. Such accounts ignore how people experience cyberspace as a distinctive place, and how current international law lacks safeguards to prevent states from exercising their sovereignty to splinter the Internet into a set of national networks. Territorial sovereignty is also hard to square with pledges by the world’s democracies to keep the Internet free, open, and global; yet it is not the only way that international law knows to define the powers of a state.
Drawing from the law of the sea, this Article argues that we should anchor the nature of state authority in cyberspace in the limited sovereign rights that coastal states possess in the waters off their shores. Unlike the plenary powers that sovereignty vests in states over their entire land territory, a coastal state’s sovereign rights weaken the further one goes out to sea, and they are subject to the rights of other states (and of their nationals) to engage in certain peaceful uses of such waters. By redefining state authority over cyberspace in terms of layers of sovereign rights that are subject to the digital rights of others, states can enact legitimate online regulations within international legal constraints that preserve the Internet’s free, open, and global character.
