The Supreme Court on Friday refused to entertain a public interest litigation (PIL) seeking a probe by the Central Bureau of Investigation (CBI) into the incident which led to West Bengal Chief Minister Mamata Banerjee injuring her leg..A Bench headed by Chief Justice of India SA Bobde asked the petitioners to approach the Calcutta High Court and granted liberty for the same, whereupon the petitioners withdrew the plea. ."It (Mamata Banerjee's leg injury) could be staged. She is shaking her legs," Advocate Vivek Narayan Sharma appearing for the petitioner contended. "Go to Calcutta High Court, allowed to withdraw with liberty to approach Calcutta High Court," CJI Bobde replied..The plea filed by three practicing lawyers said that such incidents of election violence were leading to a sustained campaign against senior officers of the Election Commission. It, therefore, sought an independent probe into the incident and also sought framing of guidelines to handle such incidents in the future. .The petitioners prayed for enhancement punishment for poll violence as well as the establishment of a temporary body to deal with election violence and to punish perpetrators..Story to be updated.
