Satyam Computer Services Limited founder B Ramalinga Raju got a temporary reprieve on Tuesday as his petition against the CBI conducting lie detector test (polygraph test) and brain mapping (F300 testing) on him and two others was referred to a division bench of the AP high court. On July 9, the XIV additional chief metropolitan magistrate allowed the CBI to conduct the forensic tests but the high court stayed the order admitting Raju's petition.
