What feature of Indian constitution makes it federal or what features makes it unitary.
As such amendments can only be made by the Union Parliament.
All India Services such as IAS and IPS have been created which are kept under the control of the Union.
Such an amendment has to be passed by majority of total members of each house of the Parliament as well as by two-thirds majority of the members present and voting there in.
However, in addition to this process, some amendments must be approved by at least 50% of the states.
The procedure of amending the Constitution in a federal system is normally rigid.
It has been the matter of debate among the scholars that whether the constitution of India is completely federal or unitary in nature.But actually Indian constitution contains both features of a federal constitution and unitary constitution.
In spite of the fact that the Indian Constitution establishes a federal structure, it is indeed very difficult to put the Indian Constitution in the category of a true federation.After this procedure the amendment is signed by the head of the state i.e; the President.Since in India important amendments can be amended through this procedure Hence, Indian Constitution has been rightly called a rigid constitution. The Union List consists of 97 subjects of national importance such as Defence, Railways, Post and Telegraph, etc.In a federal set up there is a two tier of Government with well assigned powers and functions.In this system the central government and the governments of the units act within a well defined sphere, co-ordinate and at the same time act independently. Wheare defines federal government as an association of states, which has been formed for certain common purposes, but in which the member states retain a large measure of their original independence.But for the very clear picture of this conclusion first of all we have to know that what is the federal constitution and what is unitary constitution.
