Eminent citizens including historian Romila Thapar Wednesday told the Supreme Court that the case against five activists arrested in Koregaon-Bhima case was cooked up in the name of former Delhi University Professor G N Saibaba who is serving life sentence for Maoist links. Thapar and other noted personalities, who have filed plea against the arrest of the five activists, said the case was based on 13 letters, which are in the public domain, either written or received by one Comrade Prakash, whom a lower court has said is actually Saibaba and now serving life sentence after his conviction. A bench of Chief Justice Dipak Misra and Justices A M Khanwilkar and D Y Chandrachud was told how a person currently in jail could write or receive letters. The entire case is cooked up and based on 13 letters which are in public domain. Out of 13 letters, 6-7 letters are written or received by one Comrade Prakash. G N Saibaba is actually comrade Prakash which is reflected in the trial court order. He was convicted on March 7, 2017 and is in jail. Then how can a person in jail write or receive letter, senior advocate Abhishek Manu Singhvi, appearing for Thapar and others, said. He said all intrinsic evidences were being cooked up in the name of a person who is in jail and hence the court should order an SIT probe or a probe monitored by it. Additional Solicitor General Tushar Mehta, appearing for Maharashtra government, referred to the order of trial court which convicted Saibaba and said the court had recorded that Saibaba had changed his name from Prakash to Chetan after his earlier alias was exposed to the public. Countering Singhvis contention, Mehta said that in the letters, the name Prakash refers to the chief communicator of banned organisation CPI (Maoist), and not Saibaba. The plea by Thapar and economists Prabhat Patnaik and Devaki Jain, sociology professor Satish Deshpande and human rights lawyer Maja Daruwala has sought an independent probe into the arrests and the immediate release of the five activists. The Maharashtra police had arrested the rights activists on August 28 in connection with an FIR lodged following a conclave – Elgaar Parishad – held on December 31 last year that had later triggered violence at Koregaon-Bhima village. Prominent Telugu poet Rao was arrested on August 28 from Hyderabad, while activists Gonsalves and Ferreira were nabbed from Mumbai, trade union activist Sudha Bharadwaj from Faridabad in Haryana and civil liberties activist Navlakha from Delhi. In March last year, Saibaba was awarded life sentence by a trial court in Maharashtra for his links with the Maoists. The court had also found former JNU student Hem Mishra and four others guilty of waging war against the country and supporting the ideology of the CPI (Maoist).
