New Delhi: DMK chief M. Karunanidhi's wife Dayalu Ammal Monday pleaded before a court here that she is suffering from dementia and cannot defend herself and sought discharge in a 2G-related money laundering case.
The 84-year-old Ammal also sought permanent exemption from personal appearance on medical grounds.
Ammal's counsel told Special CBI Judge O.P. Saini that she was in an unsound state of mind and was "unable to recognise anybody except close relatives and that too erratically".
He said that in such a condition, when a person is unable to converse or understand the complexities of the case, she couldn't defend herself.
The court posted for July 2 to examine witnesses.
