Hon MICHAEL WOOD (Minister of Transport): Just responding to a few of the queries that have come through from members. The first is from Mr Brown, who raised a series of questions around the regulation-making powers in respect to the maximum charges under the scheme. They'll be determined by the Minister and set through secondary legislation. The legislation itself doesn't set specific parameters on what the maximum or minimums for those should be, but, as we're discussing, the criteria by which the Minister must determine those are set in the legislation. I think that's the appropriate way to take this forward, bearing in mind that those criteria point the Minister of the day to a range of quite real-world factors, including the supply of clean vehicles, the market response, the need to have a balance within the scheme between incomings and outgoings. So, for example, if a Minister chose to set very high fees that brought in a lot of revenue, that would imbalance the scheme and the obligation under—I think, is it clause 5—is to ensure the scheme is balanced. So those sort of controls will be there as well as broader questions of political acceptability when the Minister of the day sets those levels.
