PATNA: The Nitish Kumar government 's decision to withdraw a vandalism case filed against RJD chief Lalu Prasad and his minister sons Tejashwi Prasad Yadav and Tej Pratap Yadav after an RJD-sponsored bandh last year has riled the opposition BJP, which says the move was "a case of contempt of the Patna high court".On Tuesday, the court of Patna chief judicial magistrate Om Prakash had accepted the Bihar government's plea to withdraw the case and closed it. The government's lawyer had moved an application under CrPC Section 321, which gives powers to the government to withdraw a case before conviction. On Wednesday, BJP functionary and former deputy chief minister Sushil Kumar Modi questioned the government's decision, pointing out that the Patna HC was also hearing a case related to the vandalism that took place during the bandh last July."Did the government take permission from the HC, which had taken suo motu cognizance of the disturbances, for withdrawing the case in the lower court?" Modi said.He asked if the state government would take back thousands of other such cases relating to agitations by employee unions and citizens who staged protests and blocked roads. "The state government is functioning under Lalu's pressure and that's why it decided to withdraw the case against top RJD functionaries," Modi said.Defending his family, Tejashwi on Thursday said they did not play any role in the government's decision. "No one from my family ever discussed the issue with the CM or anyone in the government," said Tejashwi, who is also deputy CM in Nitish's cabinet."The decision was taken by the department concerned."The case was registered with the Kotwali police station on July 27 under various IPC sections relating to vandalism and preventing government officials from discharging their duties. The bandh had been called to press the Centre to release caste census data.
