With the development of technical capabilities for the exploration and exploitation of the continental shelf, the desire of coastal states to expand the area of their jurisdiction in the "underwater territory" (the territory of the seabed) increased. Thanks to the activism of the judges of the International Tribunal for the Law of the Sea, the concept of the continental shelf for the purposes of international maritime law has been significantly developed. As a result, the coastal states signatories to the 1982 Convention on the Law of the Sea were able to establish the outer limit of the continental shelf, which, under certain conditions, can extend even beyond 350 nautical miles from the baseline.Disputes between states on the continental shelf mainly arise in connection with the need to distinguish between marine areas rich in sources of living and non-living resources. In such cases, it may be necessary to delineate the continental shelf between adjacent States (with a common border) or located opposite each other, i.e. their delimitation under article 83 of the Convention on the Law of the Sea. The subject of the dispute is the external legal boundary of the continental shelf of the state, where it extends beyond 200 nautical miles from the baseline of that state (the continental shelf beyond 200 nautical miles), adjoins the area that is the common heritage of mankind, outside the jurisdiction of any of the states.On the issue of determining the limits of the continental shelf beyond 200 nautical miles, the decision of the International Tribunal for the Law of the Sea of 14.03.2012 "On delimitation of maritime boundary between Bangladesh and Myanmar" is of a precedent value, since no international court has previously addressed this issue.
