Overlapping claims to internal waters in law of the sea and LOSC

Several adjacent coastal States have designated straight territorial sea baselines in a manner that generates overlapping claims to internal waters. The LOSC contains only limited references to internal waters, none of which concern delimitation or OCA management. The absence of detailed provisions in this context flows from the characterization of internal waters under customary law: Such waters appertain to the land territory of a coastal State and are subject, with limited exception, to full territorial sovereignty. The absence in the law of the sea of detailed rules concerning internal waters is a deliberate deference to the territorial rights of coastal States.
