Indian territorial waters,

Hello Kamal

Territorial waters means that portion of sea which is adjacent to the shores of a country.  At present it's 12 nautical miles.  (Its since 1967 and can't be ordinarily changed)

There is another term 'Exclusive economic zone'  which extends to 200 nautical miles from the base-line for our country.

In territorial waters a country has complete control in respect to airway, sea route as well as sea bed; however in exclusive economic zone although country has exclusive rights to use it for economic purposes , other countries have right of navigation and over-flight rights. Other countries can lay submarine cables and pipelines with consent of Indian Government.

Although  I havent read the case but I think court has referred territorial waters in terms of 'Exclusive Economic Zone' of our country.
