The Karnataka High Court has issued notices to former chief minister B S Yediyurappa and others including his son B Y Vijayendra, who is BJP state unit vice president, to appear before it on August 17 in a case alleging corruption in a housing project. The notices were issued on a petition by activist T J Abraham who alleged that Yedyurappa and others, including son and relatives, received kickbacks from a contractor to restart a stalled housing project of the Bangalore Development Authority.
