Article 35A, which provides special rights and privileges to the citizens of Jammu & Kashmir, was incorporated in the Constitution of India in 1954 by an order of then President Rajendra Prasad, on the advice of the Jawaharlal Nehru Cabinet. It gives the J&K legislature full discretionary powers to decide who 'permanent residents' of the state are. It also gives them special rights and privileges in employment with the state government, acquisition of property in the state, settling in the state, and the right to scholarships and other forms of aid that the state government provides. It also allows the state legislature to impose any restrictions upon persons other than the permanent residents regarding the above.
To guarantee these special rights and privileges, the Article says that no act of the state legislature that comes under it can be challenged for violating the Constitution or any other laws.
