There is something to verify, because if a public office holder met with a lobbyist, he or she knows they've met with the lobbyist and can verify if that meeting was reported merely by going to the lobbyist registrar's website, where it would be posted. If it is not posted, then the public office holder would have the responsibility to contact the registrar to ensure that it was posted and that the registration of that meeting was carried out.
The job of the public office holder is not only to verify the accuracy of what the lobbyist reports, but also to point out any omissions. If I met with an association of Canadian fishers and they did not post it on the website, I would be responsible to correct the record and ensure that it did get posted.
