Special NIA Court on Father Stan Swamy
After the arrest, NIA had produced Stan Swamy before Special NIA Court and had filed a charge sheet against him. The Special Court had found that Father Stan Swamy is one of the prime accused in the riot case. As a result, the court had refused his bail application many times. While refusing bail to Stan Swamy last time, the court had said that prima facie Swamy had hatched a "serious conspiracy" with members of a banned Maoist organisation to create unrest in the country and to overthrow the Government.
Special judge DE Kothalikar had said in his order that based on the material on record, it seemed Swamy was a member of a banned Maoist organisation.
"Prima facie it can be gathered that the applicant alongwith other members of the banned organisation hatched a serious conspiracy to create unrest in the entire country and to overpower the Government, politically and by using muscle power," judge Kothalikar had said in his order.
"The material placed on record thus prima facie denote that the applicant was not only the member of banned organisation CPI (Maoist) but he was carrying out activities further in the objective of the organisation which is nothing but to overthrow the democracy of the nation," the order had read.
