Mr. David Silke:

Our lens was very much on what could happen in the context of RPZ legislation finishing at the end of this year. We had a very short time for implementation. We identified five issues, the first of which was the data required for a reference or points-based system. The second issue was the complexity of those and the time it would take to explain them and get them into common knowledge. The third issue related to disputes. We felt that maybe it could initially lead to a lot of disputes. The fourth issue related to compliance. Several other countries have had problems in relation to compliance with these systems. The final issue, which is the biggest one, is that it would be quite difficult to decide what a market rent is, on which a reference rent would be based.
