The next point I want to raise: clause 42E, and this could have been interrogated more in the select committee stage. How assessments are to be calculated—got the old formula, A minus B times C minus D equals E. Fair to say, that level of mathematics was not probably my strength, although it was a very good school and the Hon Damien O'Connor, I'm sure, would agree with me on that. But what it says, under B, is the distance covered by RUC licences that the RUC collector considers would have been reasonable to purchase for the RUC vehicle during the temporary reduction period. I suppose we can look at that in the committee of the whole House stage, but it would have been good to interrogate that more in the select committee stage. What does it mean when it says, "reasonable to purchase"? I think we don't have much detail around that because it's not actually in the formula. And what will be the criteria that our RUC collectors—this role, RUC monitors; more bureaucrats by the sounds of it—will be assessing what was reasonable to order.
