Arguably, if there was a constitutional impediment, that could equally apply to the levy. If the levy can apply to land, I do not see why it cannot apply to vacant properties. It may be something we need to look at. I have not thought it out fully or put down an amendment, but it is something we should look at and consider. I am certainly going to do so. If there is any way to have a measure to push buildings and houses which are not being used back into use for those who need them, we should consider including it in the Bill.
