Here is a live case, (which I have guided for quite some time)
which shows how the spouse of Expired employees are cheated.
Average Basic Pay: Rs. 6252 (in 2002 when employee died))
Amount payable at 156% : Rs.249212
Family Pension Payable per month: Rs. 2958
Pension arrears payable upto Sep 2010: Rs.31682
Now the spouse has shell out Rs.217530 (249212-31682) and get pension of Rs.2958 per month.
When the spouse will get back her principal?
