New Delhi, July 7 Facing accusation of bias from petitioner Mamata Banerjee, Justice Kausik Chanda of the Calcutta High Court on Wednesday recused from hearing an election petition filed by the Chief Minister challenging the victory of BJP leader Suvendu Adhikari from Nandigram. The court, though, imposed a cost of Rs 5 lakh on Banerjee as fine. Justice Chanda said when the case had first come up before him on June 18, no request was made for his recusal. The petitioner had already written to the Acting Chief Justice of the HC on June 16 requesting him to reassign the case to another court but no clue was given to the Bench regarding the letter, Justice Chanda said in his 13-page order.
