The main purpose of the amendment was to provide for the appointment of a Chief Justice of the Jammu and Kashmir High Court. The amendment also made certain other changes to the Constitution, such as increasing the number of seats in the Legislative Assembly and providing for the appointment of a Public Service Commission.
The amendment was passed in response to the growing demand for greater autonomy for the state of Jammu and Kashmir. The amendment was seen as a way of giving the state more control over its own affairs.
The amendment was met with some opposition from certain sections of the population, who felt that it gave too much power to the state government. However, the amendment was ultimately passed and has been in force since 1961.
