This part of the Indian constitution contains the law in establishment, renaming, merging or altering the borders of the states or union territories.
These articles were invoked when West Bengal was renamed, and for formation of relatively new states such as Jharkhand, Chhattisgarh, Sikkim and recently Telangana.
Sikkim was a special case which was included as a completely new type of statehood under a new Article 2A and conditions mentioned in tenth schedule, and was called 'associate state'.

[6] Fisheries including in territorial waters is under state jurisdiction (entry 21 of state list, Schedule 7 of Indian Constitution) except fishing and fisheries beyond territorial waters (entry 57 of union list, Schedule 7 of Indian Constitution) which is under union jurisdiction.
