Parikh : Art. 370(3) cannot be used to amend (1) and (2). What has happened ultimately is that you require the concurrence. 1965, after that was done, Art. 370 could not be amended so easily. Definition clause can only be amended by Art. 370(3).

Parikh : If you’re making any changes in Art. 367, then you must proceed under Art. 370(2).
