We have one financial system for the whole of government at a very summarized level. So if you look at the financial statements in the public accounts, there's one financial system to produce that.
There is information that is much more detailed that is contained in each department's financial system. Each department runs their own financial system, and it provides the common data necessary for the government's financial statements at a very high level, but there is additional detail in each department. So it is more complex than that, yes.
But your point does hold that if a department is looking to exceed the money voted by Parliament, it needs to come back to Parliament to get more money, and that is why we have supplementary estimates, to augment the money that was voted by Parliament in the Appropriation Act that was linked to the main estimates.
