5. Rigid Constitution

The division of powers established by the Constitution as well as the supremacy of the Constitution can be maintained only if the method of its amendment is rigid. Hence, the Constitution is rigid to the extent that those provisions which are concerned with the federal structure (i.e., Centre-state relations and judicial organisation) can be amended only by the joint action of the Central and state governments. Such provisions require for their amendment a special majority4 of the Parliament and also an approval of half of the state legislatures.
