Did the PIO give you detailed reasons as to why he thinks Sec 8 (1)(g) and Sec 11 are applicable in the present case ?
If there is any denial of information by the PIO under Sec 8 , he must justify as to how the matter on hand is covered by the exemption. Just quoting the Section number or quoting the section "ad-verbatim" is not enough.
We get regular evasive replies like this. . However it is a good input to fight it out with PIO to ask him to explain how it comes under Section 8 clauses.
