BNP Chairperson Khaleda Zia yesterday filed a leave-to-appeal petition with the Supreme Court for staying the operation of the High Court verdict that cleared the way for the lower court to run trial proceedings against her in Barapukuria Coal Mine graft case. Barrister Mahbub Uddin Khokan, counsel for Khaleda, filed the leave-to-appeal plea with related branch of the apex court for scrapping the trial proceedings against her in the case. Now, the chamber judge of the Appellate Division will fix a date for hearing Khaleda’s leave to appeal petition. After filing the petition, Khokan told reporters that his client was not involved in any corruption. He also said that although the then deputy director of ACC Monirul Haque, who was first investigation officer of the case, submitted a final report to the commission on June 1, 2008 exempting the accused from the charges as their offence was not found in the investigation. Later, violating the ACC law, Mohamnmad Shamsul Alam, another IO of the case, submitted a charge sheet in the case to a lower court on October 5, 2008 against Khaleda and 15 others.
