Centre can lower royalties to minimise impact on mining companies post Supreme Court ruling: Ambit Capital

"Interestingly, since WB (West Bengal) has been collecting mining tax all these years, it's the only state that is deprived of enhanced royalty rate that was allowed in 1991. That's as clear a precedent as one needs. Therefore, net impact to companies from prospective dues would most likely be minimal," Ambit Capital said.
