In a civil case filed by 'A' against 'B', 'A' stated in petition that 'A' came to know from one of the relatives of 'B' that 'B' was suffering from mental problems.
So, Can the 'B' file a defamation case agianst 'A'?
If so, can 'A' simple escape by putting the blame on the relative of 'B'?
If 'A' don't have any evidence of either 'B' had mental problems or the relative of 'B' told 'A' that 'B' had such problems, who will be convicted?
