The Lobbying Act is clear in that the burden is placed on those who are engaging in lobbying activities to register. The act provides for investigatory powers by the Commissioner of Lobbying to investigate situations where it comes to light that someone who should have been registered has not registered.
It also provides for a penalty regime that includes fairly substantial fines in the event that someone violates the provisions of the Lobbying Act. But again, the Lobbying Act is very much about putting the burden on those who are engaging in lobbying activities to identify.
