The CBI's plea that as an independent agency it did not take instructions from the government was filed in the court that was in the midst of hearing a petition filed by Akhilesh seeking review of the SC's March 2007 order passed on a PIL. The SC had ordered the CBI to submit the preliminary probe report to the Centre for further action.when the matter was crucially poised before the court, there was a change in political equations with SP's 39 MPs rescuing the UPA during the 2008 trust vote on the Indo-US nuclear deal. Indebted by the SP's help, the UPA decided to pay back.The CBI filed another application on December 6, 2008, seeking permission to withdraw its October 26, 2007 plea. The logic behind the flip-flop - a grave error in the calculation of assets had led the agency to believe that the SP chief and his family members had amassed wealth disproportionate to their known sources of income. A bench of Justices Altamas Kabir and Cyriac Joseph reserved orders on the plea. After three years, the order is yet to come and Justice Joseph has retired. This would warrant a fresh hearing in the case and possible fresh trouble.What if the CBI does a somersault again? The fallout could be grave: prosecution of all the four important members of the SP first family.
