Odisha is set to voice its opposition to some of the contentious provisions in the Mines and Minerals (Development & Regulation) Bill-2011 that the state government feels may undermine the federal structure of the constitution.

In May this year, Chief Minister Naveen Patnaik had shot off a letter to Prime Minister, Manmohan Singh complaining that the MMDR Bill sought to transfer certain powers and functions now being exercised by states to the Centre.
