p.esakkimuthu,
When AA gave a order to
PIO to furnish the information, did he specify something like "within XX days" or "immediately" or "urgently" or anything else ?
I read the relevant portions of the act several times but things are not clear.
My personal opinion is that a total of 45 days can be allowed for
PIO to reply from the date of the first appeal.
If reply is not received within 45 days, you can complain to the
CIC or
SIC as may relevant in the particular case.
