- Three-mile limit
The three-mile limit refers to a traditional and now largely obsolete conception of the
international law of the seas which defined a country'sterritorial waters , for the purposes of trade regulation and exclusivity, as extending as far as the reach ofcannon s fired from land.In "
Mare clausum " (1635)John Selden endeavoured to prove that the sea was in practice virtually as capable of appropriation as terrestrial territory. As conflicting claims grew out of the controversy, maritime states came to moderate their demands and base their maritime claims on the principle that it extended seawards from land. A workable formula was found byCornelius Bynkershoek in his "De dominio maris" (1702), restricting maritime dominion to the actual distance within which cannon range could effectively protect it. Most maritime nations adopted this principle, which developed into a limit of threenautical mile s.Since the mid-20th century, numerous nations have claimed territorial waters well beyond the traditional three-mile (5 km) limit. Commonly these maritime territories extend convert|12|nmi|km from a
coastline , and this was eventually established as the international norm by the 1982United Nations Convention on the Law of the Sea . As a result, the three-mile limit has become largely obsolete.As of 2007 , onlyJordan ,Palau , andSingapore retain it.ee also
