Mining baron Gali Janardhana Reddy, who is out on bail, cannot campaign in Karnataka's Ballari for the May 12 election, the Supreme Court said today. Janardhana Reddy was barred from Ballari as a condition for his release on bail in 2015. The court today rejected his request for a 10-day reprieve from the ban to campaign for his brother Somasekhara Reddy, a BJP candidate in Ballari, as well as cast his vote in the election next Saturday.
