Centre on Thursday admitted before the Supreme Court that something went wrong with the coal blocks allocation and that it could have been done in a more refined manner. Attorney General G E Vahanvati told a three-judge bench headed by Justice R M Lodha that something turned out to be wrong though the decision were made in in good faith. Vahanvati submitted the government would next week make its stand clear on the issue. Centre in September 2013 had submitted that coal blocks allocation was merely a letter of intent and does not confer any right to the companies over the natural resource which is decided by the state government.
