Facing flak over controversial Rashtirya Janata Dal strongman Mohammad Shahabuddins release from jail, the Bihar government is preparing to file an appeal in the Supreme Court against the bail granted to him by the Patna high court.

"This has been an established process followed by Nitish Kumar government in the past 11 years that if the state is not satisfied with the bail of somebody, it goes in appeal in higher court," Janata Dal-United spokesperson Ajay Alok said.

"It has been done in the past and would be followed in the present case of Shahabuddin too," he said.

In such cases the concerned district administration makes a proposal if any condition of the bail has been violated and an appeal is moved for cancellation of bail, the spokesperson said.

With the Bharatiya Janata Party questioning the delay in appeal for cancellation of bail of the former RJD MP, the JD-U spokesperson said courts were closed on account of festival.

Meanwhile, Siwan Superintendent of Police Saurav Kumar Sah said the district police was scrutinising if any condition of the bail has been violated in the case of Shahabuddin.
