what is a three-mile rule or the 12-mile rule??

Question

territorial rule

Answer 1

A sovereign state has complete jurisdiction over internal waters, where not even innocent passage is allowed. Territorial waters extend up to 12 nautical miles (22 km) from the mean low water mark adjacent to land, or from internal waters, as per the 1982 United Nations Convention on the Law of the Sea. The mean low water mark may be an unlimited distance from permanently exposed land, provided that some portion of elevations exposed at low tide but covered at high tide (like mud flats) is within 12 nautical miles of permanently exposed land. Completely enclosed seas, lakes, and rivers are considered internal waters, as are waters landward of lines connecting fringing islands along a coast or landward of lines across the mouths of rivers that flow into the sea. Bays are defined as indentations between headlands having an area greater than that of a semicircle. If they do not exceed 24 nautical miles (44 km) between headlands then they are internal waters; if their entrance is wider, then that portion landward of a 24 nautical mile straight line that touches opposite low-water marks across the bay positioned to contain the greatest water area are internal waters. All archipelagic waters within the outermost islands of an archipelagic state like Indonesia or the Philippines are also considered internal waters.

An exclusive economic zone extends for 200 nautical miles (370 km) beyond the baselines of the territorial sea, thus it includes the territorial sea and its contiguous zone.[3] A coastal nation has control of all economic resources within its exclusive economic zone, including fishing, mining, oil exploration, and any pollution of those resources. However, it cannot regulate or prohibit passage or loitering above, on, or under the surface of the sea, whether innocent or belligerent, within that portion of its exclusive economic zone beyond its territorial sea. Before 1982, coastal nations arbitrarily extended their territorial waters in an effort to control activities which are now regulated by the exclusive economic zone, such as offshore oil exploration or fishing rights (see Cod War). Indeed, the exclusive economic zone is still popularly, though erroneously, called a coastal nation's territorial waters.

From the eighteenth century until the mid twentieth century, the territorial waters of the British Empire, the United States, France and many other nations were three nautical miles (6 km) wide. Originally, this was the length of a cannon shot, hence the portion of an ocean that a sovereign state could defend from shore. However, Iceland claimed two nautical miles (4 km), Norway claimed four nautical miles (7 km), and Spain claimed six nautical miles (11 km) during this period. During incidents such as nuclear weapons testing and fisheries disputes some nations arbitrairly extended their maritime claims to as much as fifty or even two hundred nautical miles. Since the late 20th century the "12 mile limit" has become almost universally accepted. The United Kingdom extended its territorial waters from three to twelve nautical miles in 1987.

Answer 2

International borders at sea. Some countries like the U.S. Claim territory at 12 miles but the standard for International law is 3 miles.

Answer 3

The three mile rule (cannon shot rule) was extended to 12 miles in 1982.


* Coastal States exercise sovereignty over their territorial sea which they have the right to establish its breadth up to a limit not to exceed 12 nautical miles; foreign vessels are allowed "innocent passage" through those waters;

Answer 4

International Maritime law. Allows that country to board ships etc within its Territorial waters to enforce its laws, arrest offenders for cause, detain and search ships suspected of illegal trading, spilling oil or debris and a host of offer offenses
