Chandan,
In the First Appeal, please argue that if
PIO was not clear about Items 3,4 & 5 of your
RTI Application, he could have asked for clarification or asked you to come and inspect the records/files.
Please ask for inspection of all relevant files, records, memos, etc. on this subject.
For items 6 & & you can argue in the First Appeal that since you are an "affected" party, you can ask for reasons under Sec 4(1)(d) of the
RTI Act.
