For the third time in recent weeks, the Supreme Court expressed its dissatisfaction with the handling of the case involving farmers run over in Lakhimpur Kheri last month, allegedly by Union Minister Ajay Mishra's son Ashish Mishra. "We don't want to add to political overtones. Let a retired (High Court) judge oversee (the case)," Chief Justice of India NV Ramana said, berating the Uttar Pradesh government over poor progress in the investigation.
