In a major blow to the corporate sector, the Supreme Court yesterday quashed allocation of 214 out of 218 coal blocks alloted to various companies since 1993 terming it as "fatally flawed" and allowed the Centre to take over operation of 42 such blocks which are functional.
The apex court said the beneficiaries of the illegal process "must suffer" the consequences and refused to show sympathy to private companies which submitted that Rs 2.87 lakh crores have been invested in 157 coal blocks and Rs 4 lakh crores in end-use plants.
The broader market was also weak with the benchmark Sensex closing with a loss of 276.33 points at 26,468.36.
