I would like to ask the Minister to check with officials if my assessment of the current tax law is correct, because this is a significant departure in principle from what we are doing. Now, we shouldn't be surprised by that. We've heard a lot in terms of departures from principles, and the non-deductibility of interest expenditure, which the Government signalled today and which they're going to do a lot of work on, is an egregious breach of those principles where taxable income should be gross income less legitimate expenses. An interest expense is legitimate, according to the Government, in every other circumstance but the gaining of income by the offering of residential property rentals.
