The NSICOP's process is really parallel to any parliamentary process. There are statutory rights to obtain information, but the parliamentarians who are members of that committee are bound by their clearance and the Security of Information Act. There is also the exception relating to parliamentary privilege.
So we are still in the realm of parliament, of government, that is, parliamentary privileges do not apply. A member of the NSICOP could not rise in the House to disclose information. An exception is provided.
