The Supreme Court on Friday called the death of CBI Special Court and Additional Sessions Judge Brijgopal Harkishan Loya a "serious issue" and asked the Maharashtra government to produce all documents related to the case.A division bench of Justice Arun Mishra and Justice M.M. Shantanagoudar asked the Maharashtra government to file a reply and documents by January 15, the next date of hearing.The court was hearing two separate pleas seeking an independent probe into the death of judge Loya, who presided over the case in connection with the alleged staged encounter of suspected extortionist Sohrabuddin Sheikh.The two pleas were filed by Maharashtra-based journalist B.R. Lone and Congress leader Tehseen Poonawala.Senior advocate Dushyant Dave, representing the Bombay Lawyers Association, told the bench that the Bombay High Court was seized of the matter and the bench should not hear the plea.Senior advocate Indira Jaising, appearing for journalist Lone, also said that matter should not be heard by the apex court. The bench said it would consideice Dipak Misra over the matter of allocation of benches.Raja later told media persons that he knew Justice Chelameswar for quite a long time and thought he should find out what happened, since the judges have gone public with their complaints."Parliament will have to devise a method to sort out problems like this in the judiciary," the CPI leader said.
