On my last appearance, I talked mainly about proof of identity. An address is shown for people on the registry. Now you are saying that that address is not adequate, that we need proof that the person actually lives at that address.
It is true that changes could have been made to the register. The person could be at the right address and say that that is in fact where he or she lives. People in the polling station should then require that the individual provide proof of this. The person could then say that he or she has no such document, but does have an I.D. card. That is a problem.
I do not think there is an easy solution to it. I think that you should look into it and that the new Chief Electoral Officer should have an opportunity to work on that with you.
