The CBI today moved the Supreme Court seeking cancellation of the bail granted bail to B Ramalinga Raju,tainted founder of Satyam Computers,by the Andhra Pradesh High Court in the Rs 14,000 crore scam case. The probe agency has challenged the High Court decision contending that Raju,who was the chairman of the company,may influence the witnesses majority of whom are his former employees. The High Court on August 18 had allowed Rajus bail on the ground that all other accused in the case including his brother Rama Raju,former Satyam CFO V Srinivas and three others former IT company employees G Ramakrishna,Venkatapathi Raju and Ch Srisailam were granted bail by it. T Srinivas,Satyams auditor was granted bail by the Supreme Court. However,the CBI contended that there cannot be any parity between Raju and others as far as the seriousness of the case is concerned. . parity can not be claimed by the respondent (Raju) that he is on par with T Srinivas who was granted bail by the Supreme Court on February 4,2010. Parity could be claimed only if the roles of two persons (Raju and Srinivas) are similar or identical, the CBI said in its petition while appealing against the bail granted to Raju on furnishing two personal bonds of Rs 20 lakh each. The probe agency,in its petition filed by advocate Arvind K Sharma submitted that the roles of Srinivas and Raju was quite different in the scam and the latter could not be granted bail on that criteria. Over Rajus health the CBI submitted that "his condition is improving" and he is "showing positive response to the treatment" and hence the bail should be cancelled.
