Jeevan, here I am assuming that you want to file an RTI application or complain to CIC and keep it anonymous because you are in some manner related to the public authority. In this case you can simply get the application filed by someone else familiar to you. Complaint to CIC, if required, can be filed by the same person. The other person can ask for any information even if it relates to you.
Am sorry, but don't you think by being Anon, I can ask more questions fearlessly and without any worry that some goons will be sent after me by the person who I may be 'exposing'? I am very confused. Thanks.
