The Supreme Court on Tuesday agreed that the government had reasons to doubt its verdict laying down auction as the only way of allocating natural resources, in what is seen as an indication of a significant judicial rethink. "On cancellation of spectrum licences allotted without following a transparent system, there is no doubt about its correctness. But if one reads the judgment to mean that auction must be applied for allocation of all natural resources, then does it not create a doubt about the law laid down by the court?" said a five-judge constitution bench of Chief Justice S H Kapadia and Justices D K Jain, J S Khehar, Dipak Misra and Ranjan Gogoi.
