Can I request information from any Member of Parliament?

No, only public authorities and members of parliament who are Ministers are subject to the Act.  The Act defines a Minister as a person responsible for the administration of an agency and it is information in their possession that can be requested. A Minister is more than a member of the back bench and has a specific area, or specific areas of responsibility as a member of Cabinet. You can request information from Ministers, but you cannot request information from other Government members or members of the Opposition.
