Constitutional amendment modifies Article 168 to insert additional provinces into the list of legislative assemblies. The amendment inserts 'Mysore' after 'Madras' in Article 168(1)(a) and provides for insertion of 'Madhya Pradesh' after 'Bombay' in the same sub-clause, the latter insertion to take effect on a date to be appointed by the President by public notification, thereby modifying the textual list of territorial units in Article 168(1)(a).
