"In the charge sheet, Sasikala, Illavarasi and Sudhakaran have been mentioned as benamigars (benami holders) and hence, A-1 - Jayalalithaa - has no obligation to explain the acquirement of such properties. Those cannot be her properties," L Nageswara Rao said.
The submissions were made before Justice C R Kumaraswamy who is hearing appeals filed by Jayalalithaa and three others challenging their conviction in the case.
The special bench, set up at the direction of the Supreme Court on December 18 to decide Jayalalithaa's plea in three months, is holding day-to-day hearing.
He also argued that the three others should not be tried under Prevention of Corruption Act as they were not public servants and hence they should be tried under Benami Transactions (Prohibition) Act, 1988.
