NEW DELHI: The Central Bureau of Investigation (CBI) may drag the Centre to court over the Ishrat Jahan fake encounter case, following the home ministry's reluctance to part with the files related to the case despite agency's request more than a month ago.The CBI had recently raised the matter with home secretary Anil Goswami and impressed upon him the importance of the files for investigation, a top official told ET. "We are still waiting for a final word from the ministry. If the files are not handed over soon, we will inform the Gujarat High Court , which is monitoring the case, and the government will need to reply to court," said the official, who did not wish to be named.CBI had written to the home ministry on June 21, asking for the files pertaining to the filing of two apparently conflicting affidavits by the ministry in the Gujarat High Court in 2009."Right now, there is no decision in the home ministry on whether to hand over the files to the CBI," a home ministry official admitted. "There is no laid-down procedure for sharing with a probe agency documents of such secret and sensitive nature pertaining to terrorism cases. However, if the judiciary intervenes and asks us to do so, we will have no choice but to comply."The dilly-dallying by the home ministry is expected to delay the CBI's supplementary charge sheet, in which the Intelligence Bureau (IB)'s special director Rajendra Kumar and three other officers may be named as accused.
