Yes it does. I don't have an analysis, but I look at this from two perspectives. From the departmental perspective we are positioned to provide information to serve parliamentarians' needs for decision-making when they need and want it. So that is not a big issue, aside from the workload, etc.
From the decision-makers and parliamentarians, the main estimates' tabling date is mandatory by the Standing Orders, whereas the budget timeline is not necessarily mandatory. So the budget could be tabled in February, March, or another time. If there is a need to have the budget at a different time from votes on the estimates but to have a more complete picture at the time of voting on the estimates, the budget could move to a different time.
There are other options you could consider, such as starting the year with interim supply, as we do now, and then voting later in the year once parliamentarians have a more complete picture, including on budgetary items. This will have impacts, of course, but the benefit would be a streamlining of the supplementary estimates exercise. Instead of having three you may need to have one or two, because a vote has occurred on a much more complete picture after the main estimates or after entering supply.
