Justice R. S. Sarkaria Commission was appointed in June 1983. It stressed on cooperative federalismand\ noted that the federalism is more a functional arrangement for cooperative action than a static institutional concept. At the same time, it did not equate strong centre with centralization of powers because overcentralisation leads to blood pressure at the centre and anaemia at the periphery.
M M Punchhi Commission was set up by UPA Government in 2007 and it gave its recommendations in 2010. Some of the important recommendations are as follows:

• There should be a consultation process between union and states via Interstate Council for legislation on concurrent subjects.
• Regarding state bills, the President’s pocket veto should end and there should be a reasonable time (6 months) in which president communicates his decision.
• The treaty making powers of union should be regulated and states should get greater participation in treaties where interests of states are involved.
• Governor should get clear guidelines for appointment of Chief Ministers so that he does not mis-uses his discretionary powers in this context. etc.
• Rajmannar committee was set up by DMK government in Tamil Nadu in 1969. Apart from making a call for immediate constitution of Inter-state Council, this committee made following recommendations:
• Union government should not take any decision without consulting the inter-state council when such decision can affect the interests of one or more states.
• Every bill which affects interests of the states should be first referred to inter-state council before it is introduced in parliament.
• Article 356 should be used only in rare cases of complete breakdown of law and order in state. etc.
