Generally speaking, the executive process that we were describing here was to give members an understanding of the process that the government uses to develop the main estimates, which then go in front of Parliament for spending approval. The government has no legal authority to spend without it having been provided for in a vote, so we do have the government contingencies vote, for example.
The fiscal framework may set aside reserves for the government to plan to use funds that hadn't been specifically planned, but, with the exception of TB vote 5, no such plans or changes in the fiscal framework can actually give effect to spending without coming before Parliament through either main or supplementary estimates.
