Additional District Sessions Judge R Shanmuganadhan set aside the order of Judicial Magistrate-I O, convicting Kalyanasundaram and two others and sentencing them to two years imprisonment in January this year, saying the prosecution had failed to prove the charges and also that the submitted documents were forged.
The prosecution case was that Kalyanasundaram, elected on an AINRC ticket from Lawspet, had allegedly entered into a criminal conspiracy with Aadhavan, a teacher in a government school, and Rajinikanth, a clerk in Education Department, and used forged documents to appear for the exam in September 2011 in Tindivanam.
He was dropped from the Rangasamy-led ministry as soon as the trial had commenced in 2012.
