Bengaluru: Kerala will oppose the Centre's amendments to the Mines and Minerals (Development and Regulation) Act, 1957, arguing that curbs on states' powers to levy taxes and cess on mineral-bearing land would erode their constitutional powers and cause significant revenue losses.Chief minister VD Satheesan said the state would formally register its protest and explore legal remedies if the Centre moves to enforce the amended law. Both Houses of Parliament have passed the Mines and Minerals (Development and Regulation) Amendment Bill, 2026.The amendment seeks to invalidate state levies imposed before its commencement but not yet deposited or recovered. Satheesan described the provision as a "serious encroachment" on the constitutional powers of states and a threat to India's federal structure.
