It's very hard for us to second-guess the department on costs for some of these bills. They are accountable for preparing the cost estimates based on the guide that we require them to use. Also, their chief financial officers sign off on the costs. If they cannot identify a cost in some cases, they will not be signing a document saying that this is going to cost x millions of dollars and we're going to need funding for it.
We have to take their word for those cost estimates, since they are accountable. They've done their calculations. They have done their analysis. We will see later on if there is a problem because they have underestimated the costs. Then they will certainly have to come to us, and we will have a look at that point. But it is not in their interests to underestimate the costs. If they underestimate the costs, there won't be any funding for it.
